About our business
Eldorado is one of the world’s lowest cost gold producers, with new mines, robust margins and a strong balance sheet. Our international expertise in mining, finance and project development places us in a strong position to grow in value and deliver superior returns for our shareholders as we create and pursue new opportunities in gold and other resources.
Our goal is to produce approximately 1.5 million ounces of gold annually by 2015. Our strategy is to actively pursue growth opportunities by discovering deposits through grassroots exploration projects and acquiring advanced exploration, development or low-cost production assets with a focus on Brazil, China, Greece, Turkey and the surrounding regions, preferably with the potential for increased mineral resources.
All of our mining and operations comply with local and international environmental standards. We implement practices described in our environmental impact assessment and feasibility studies to maintain compliance.
We employ approximately 5,348 people and contractors worldwide, with the majority from the local communities near our operations. We invest in education programs and we partner with local communities to create new opportunities for economic development.
As of December 31, 2011, we had hourly workers, contractors and permanent employees in six countries. We also engage a number of contractors to work on specific projects. The table shows the approximate number of personnel working at our operations and those acquired through European Goldfields by country at December 31, 2011.
Turkey | 1,308 |
China | 3,199 |
Brazil | 301 |
Greece | 407 |
Canada | 44 |
Romania | 89 |
Total | 5,348 |
Most of our employees are unionized. The labour agreement at Kişladağ is valid for a three-year term and was renewed on December 31, 2009. Union membership at Tanjianshan is voluntary with most hourly workers included and using individual Bargaining Agreements. Collective Bargaining agreements are in force at the rest of the operations except for Efemçukuru. Efemçukuru is currently in the process of formalizing the collective bargaining agreement. This should be concluded early in 2012. We consider the employee relations to be good.
We work to maintain a good safety record by investing in environmental, health and safety training at our operations, and measure our results by tracking the number of lost-time incidents (LTI), and their frequency per million man hours worked (LTIFR). This year we significantly strengthened the safety group in our Chinese operations where the safety culture can still improve. That being said, our Chinese statistics are showing LTIFR rates similar to our other operating jurisdictions. Extra information will be available when Eldorado publishes its first sustainability report in the 2011 annual report. This information will also be available on the Eldorado website.

The table below shows our LTI performance for 2011.
Total hours worked | Lost-time incidents (LTI) | Lost-time incident frequency rate (LTIFR) | ||
Turkey | Kişladağ | 2,167,875 | 4 | 1.85 |
Efemçukuru | 1,623,752 | 5 | 3.08 | |
China | Tanjianshan | 1,699,551 | 3 | 1.76 |
Jinfeng | 3,356,510 | 5 | 1.49 | |
White Mountain | 2,389,810 | 5 | 2.09 | |
Eastern Dragon | 857,124 | 0 | 0.00 | |
Brazil | Vila Nova | 713,780 | 5 | 7.00 |
Total | 12,808,902 | 27 | 2.11 |
We had an overall lost-time incident rate of 2.11 this year, which compares favourably with industry benchmarks in Canada and Australia. In addition, Eastern Dragon, Vila Nova and White Mountain employees all completed a full year without any lost-time incidents (the five incidents at each of White Mountain and Vila Nova were all attributed to contractors). Vila Nova’s higher rate was mainly due to a high contractor turnover and low contractor skills.
For further information please see page 9 of our 2011 annual report.
Industry factors that affect our results
Gold market and price
Gold is used mainly for product fabrication and investment. It is traded on international markets. The London AM price fixing for gold on December 31, 2011 was $1,574.50 per ounce.
Foreign currency exposure
All of our revenues from gold sales are denominated in US dollars, while the majority of our operating costs are denominated in the local currencies of the countries we operate in. We monitor the economic environment, including foreign exchange rates, in these countries on an ongoing basis.
The table below shows the foreign exchange gains/(losses) realized in the last three financial years:
As at December 31 | |
2011 | $5,367,000 |
2010 | ($2,712,000) |
2009 (Canadian GAAP) | $2,966,000 |
Gold hedging
We monitor and consider the use of a variety of hedging techniques to mitigate the impact of downturns in the gold market.
As of the date of this AIF, we do not have any gold or currency hedges. Our future hedging activities will depend on an ongoing assessment of the gold market, our hedging strategy, financing restrictions and other factors.
2011 Annual information form 7
An overview of our business
Exploration | Our exploration programs include a blend of mine drilling, advanced stage projects and grassroots programs. Most of our exploration programs are in the countries in which we operate China, Turkey, Greece, Brazil and Romania and are conducted through our regional exploration offices. Our generative exploration and business development teams actively pursue new early-stage project opportunities both within our focus jurisdictions and new regions. |
Mining and milling | Ore and waste are removed from deposits by underground and open pit mining methods. The ore is then treated to extract gold. The waste is placed on an engineered dump for subsequent rehabilitation. The ore is treated using different methods depending on its metallurgy and grade. This may include heap leaching, crushing, milling, flotation, roasting, bacterial leaching and carbon-in-leach methods for gold extraction. |
Refining and sales �� | The gold doré produced at Kişladağ is refined to market delivery standards by Valcambi SA in Switzerland and various refineries in Turkey. Gold doré from our Chinese operations is sold to a variety of local refiners. The prices received for the doré are based on the Shanghai Gold Exchange and the spot price. Iron ore is sold on the spot market to Chinese or European interests through various agents. |
Except as otherwise noted, Norman Pitcher, P. Geo., our Chief Operating Officer, is the Qualified Person under NI 43-101 responsible for preparing and supervising the preparation of the scientific or technical information contained in this AIF and verifying the technical data disclosed in this document relating to Kişladağ, Efemçukuru and Jinfeng.

1 We calculate costs according to the Gold Institute Standard. |

3 Cash operating costs and total cash cost are non-IFRS measures. See page 9 of the MD&A for more information. |
2011 Annual information form 9
How we measure our costs
Costs are calculated using the standard developed by The Gold Institute, a worldwide association of suppliers of gold and gold products of leading North American gold producers.
The Gold Institute stopped operating in 2002, but its standard is still widely used in North America to report cash costs of production. Adoption of the standard is voluntary, so you may not be able to compare the costs reported here to those of other companies.
Cash operating costs
Cash operating costs include the costs of operating the site, including mining, processing and administration. They do not include royalties and production taxes, amortization, reclamation costs, financing costs or capital development (initial and sustaining) and exploration costs.
Cash operating costs are divided by ounces sold to arrive at cash operating cost per ounce of production.
Total cash cost
Total cash cost is cash operating costs, plus royalties and production taxes and off-site administration costs.
Cash flow from operations before changes in non-cash working capital
We use cash flow from operations (or operating activities) before changes in non-cash working capital to supplement our consolidated financial statements, and calculate it by not including the period to period movement of non-cash working capital items, like accounts receivable, advances and deposits, inventory, accounts payable and accrued liabilities.
This is a non-IFRS measure, which we believe provides a better indication of our cash flow from operations and may be meaningful in evaluating our past performance or future prospects. It is not meant to be a substitute for cash flow from operations (or operating activities), which we calculate according to IFRS.
Since there is no standard method for calculating non-IFRS measures, they are not a reliable way to compare us against other companies. Non-IFRS measures should be used with other performance measures prepared in accordance with IFRS
Production outlook, guidance and estimates are forward-looking information
Our production outlook, guidance and estimates are forward-looking information (see page 1). We made several assumptions when they were developed and actual results and events may be significantly different from what we currently expect due to the risks associated with our business.
Assumptions
● | future events |
● | economic, competitive and regulatory conditions |
● | financial market conditions |
● | future business decisions, including, without limitation, a continuation of existing business operations as they substantially currently exist. |
Risks
● | global and local economic conditions |
● | pricing and cost factors |
● | unanticipated events or changes in current development plans, execution of development plans, future operating results, financial conditions or other aspects of our business |
● | unfavorable regulatory developments that could cause actual events and results to vary significantly from what we expect |
10 Eldorado Gold Corporation
Environmental Policy
Eldorado has implemented in 2011 an environmental policy which states that the Company and its subsidiaries are committed to protecting all aspects of the natural environment of the areas in which we work. This is a core value of Eldorado Gold and applies to all elements of the mining cycle including exploration, development and operations.
To address this protection, Eldorado and its subsidiaries will:
● | Comply with all applicable environmental regulations and international best practices |
● | Share environmental performance with local communities, government agencies and stakeholders |
● | Provide the necessary training, equipment and systems to our employees and contractors to address the protection of the environment and the most efficient use of non-renewable resources |
● | Design and operate facilities that are based on the efficient and economic use of energy and materials and the protection of the environment |
● | Identify, evaluate, manage and audit scientifically the potential impact of our projects from inception through to closure. |
This policy is placed on notice boards on all of our operations. Eldorado’s properties are routinely inspected by regulatory staff along with local community members to determine that the properties are in compliance with applicable laws and regulations as well as the company’s Environmental Policy and standards. Eldorado also has closure plans for all of its operations. This allows us to properly budget for the costs associated with implementing the required closure provisions are properly budgeted for.
Health and Safety Policy
In 2011, Eldorado also implemented a health and safety policy. The health and safety of our employees and local stakeholders is a core value of Eldorado Gold. Central to that value is our commitment to provide our employees with both a safe working environment and the skills necessary to perform their tasks in a safe manner.
To achieve these goals, Eldorado and its subsidiaries will:
● | Promote safety as a core value within all levels of the organization |
● | Provide adequate safety and job training to all employees so that the risks associated with any task are understood and mitigated |
● | Comply with all applicable health and safety regulations and international best practices |
● | Set up effective safety management systems at all mine sites so that health and safety goals can be set and results measured and evaluated |
● | Promote a health and safety culture where all employees and contractors understand and take responsibility for their own safety and that of their fellow workers. |
This policy is also placed on notice boards on all of our operations as well as being made available on Eldorado’s website. Also, in 2010, Eldorado implemented an Environmental, Health and Safety (EH&S) Committee comprising selected members of the Board of Directors. Their task is to oversee the environmental, health and safety policies. They also monitor the EH&S initiatives undertaken by the Company and to focus on any specific EH&S issues or initiatives.
Corporate Responsibility
For us, being a responsible corporate citizen means investing in infrastructure, economic development and health and education in the communities where we operate so that we can enhance the lives of those who work and live there.
Over the past decade, we have operated mines in Mexico, Brazil, Turkey and China. We continue to grow our operations in Turkey, China, Brazil, Greece and Romania. We are proud of our record of
2011 Annual information form 11
implementing industry best practices that minimize environmental impacts while maximizing social and economic benefits.
Responsibility throughout the Life of the Mine
Exploration
During exploration, while we conduct geological surveys and sampling to determine the existence and location of an ore deposit, we initiate dialogue and meet with local community members to identify their main social and environmental concerns and to better understand their needs.
Development
During the development stage, we complete a feasibility study that outlines the economics, optimal mining method and mineral recovery process for the project, including closure considerations. We conduct extensive environmental testing and studies to establish baseline data and characteristics for air, water, soil and biodiversity. All this information becomes part of the Environmental Impact Assessment (EIA) that we file with the appropriate authorities.
We also begin infrastructure development initiatives that include improving roads, building sewage systems and drilling water wells, according to the needs of the communities.
Construction and training
We make it a priority to hire local residents, training all employees and instructing construction contractors in the best environmental, health and safety practices, procedures and controls. Based on our dialogue with the local community, we identify gaps in skills, provide on-the-job training and work with local technical schools and universities to enhance their mining-specific programs to help increase prospects of employment.
Mining and processing
All our mining operations comply with local and international environmental standards. We implement the practices described in our EIA to mitigate any potential environmental impact of a mine's construction and operation.
Consultation with local communities continues throughout the mining and processing cycle. As part of our commitment to protecting the environment, we continually monitor the quality of air, water and soil. We also implement programs to preserve biodiversity, monitor noise and dust levels and implement waste reduction and recycling programs throughout our operations.
To ensure a healthy and safe work environment, our employees are trained on an ongoing basis, both in theory and in practice. These training programs have helped to minimize accidents and occupational illnesses.
We employ more than 5,000 employees and contractors worldwide, the majority of whom are from the local communities near our operations. The competitive salaries and benefits we pay our employees and contractors improve their families' standard of living.
In addition to creating jobs in local communities, we promote many sustainable economic development initiatives. Since the life of any mine is limited, we encourage and work with local communities to create new opportunities for economic development.
Reclamation and closure
During the mine's operation, we conduct research to establish best reclamation practices. These reclamation activities are concurrent with mine operations to the extent possible. Financial provision is made for closure costs that will occur.
12 Eldorado Gold Corporation
Once a mine is no longer profitable to operate, we close the mine site and conduct reclamation activities so that the environment can successfully transition to a productive ecosystem.
We have an excellent record on mining closure and reclamation. In October 2000, we were the first company to receive a final full regulatory environmental release from the Mexican government for reclamation activities at our La Trinidad mine near Rosario, Mexico. The former mine became a lake capable of supporting fish.
As part of our continued move to enhance corporate responsibility, Eldorado is publishing information in its first sustainability report, is in discussions on the Cyanide Code (Code) and with the International Cyanide management Institute to be a signatory and has completed the Carbon Disclosure Project (CDP) Questionnaire for 2012.
Sustainability Report
We are pleased to report that the first Sustainability Report will be published in the Annual Report in 2012. This report follows the Global Reporting Initiative (GRI) format and will be published to a Level ‘C’. The Global Reporting Initiative (GRI) is a generally accepted framework for reporting on an organization’s economic, environmental and social performance. The GRI Reporting Framework contains general and sector-specific content for reporting an organization’s sustainability performance.
International Cyanide Management Code
The Cyanide Code is an industry voluntary program for gold mining companies. It focuses exclusively on the safe management of cyanide and cyanidation of mill tailings and leach solutions. Companies that adopt the Code must have their mining operations that use cyanide to recover gold audited by an independent third party to determine the status of Code implementation. Those operations that meet the Code requirements can be certified. A unique trademark symbol can then be utilized by the certified operation. Audit results are made public to inform stakeholders of the status of cyanide management practices at the certified operation.
The objective of the Code is to improve the management of cyanide used in gold mining and assist in the protection of human health and the reduction of environmental impacts.
Eldorado intends to become a signatory to the Cyanide Code in 2012 and to nominate all of its cyanide-using operations. While there are issues in certain jurisdictions with regard to the legal requirements involved in purchasing and using cyanide, Eldorado will require that as a minimum, all of its operations are working to best practices with regard to cyanide and will persuade our suppliers and transporters to join us in becoming signatories also.
Carbon Disclosure Project
The Carbon Disclosure Project is an independent not-for-profit organization aiming to create a lasting relationship between shareholders and corporations regarding the implications for shareholder value and commercial operations presented by climate change. Eldorado intends to submit its first report in 2012. While the data initially presented maybe be of limited value, it will form a baseline for future reports.
Climate Change Risks
Climate change refers to any changes in climate over time that are directly or indirectly attributable to human activity. This includes changes such as weather patterns, increased frequency of extreme weather events, temperatures, sea levels and water availability. We recognize that climate change is an international and community concern which may affect our business and operations directly or indirectly as described below.
2011 Annual information form 13
Increased Regulation
Governments at all levels are moving towards enacting legislation to address climate change such as requirements to reduce emission levels and increase energy efficiency. Where legislation has already been enacted, regulation regarding emission levels and energy efficiency are becoming more stringent. Costs associated with meeting these requirements can be offset by increased energy efficiency and technological innovation. However, there is no assurance that compliance with such regulation will not have an adverse effect on our results of operation and financial condition.
Sea Level Rise
Our current operations are not directly threatened by predictions of rising sea levels. However, changes in sea levels could have indirect effects on our operations such as potentially affecting any necessary ocean transportation or shipping facilities. This could then have an indirect effect on our operations.
Extreme Weather Events
Extreme weather events (such as prolonged drought, increased periods of snow and increased frequency and intensity of storms) have the potential to disrupt our operations and the transport routes we use. Where appropriate, our facilities have developed emergency plans for managing extreme weather conditions; however, extended disruptions to supply lines could result in interruption to production which may adversely affect our results of operations and financial condition.
Resource Shortages
Our facilities depend on regular and steady supplies of consumables (diesel, reagents etc.) to operate efficiently. In the event that the effects of climate change cause prolonged disruption to the delivery of essential commodities, our production efficiency may be reduced which may have adverse effects on our results of operations and financial condition.
Competition
We compete with other mining companies for acquiring mineral claims, permits, concessions and other mineral interests as well as for recruiting and retaining qualified employees. There is significant competition for the limited number of gold acquisition opportunities and, as a result, we may be unable to acquire attractive gold mining properties on terms we consider acceptable.

About the property
Kişladağ is in a rural area in west-central Turkey, between the city of Izmir (180 km to the west on the Aegean coast) and Ankara (the capital city, 350 km to the northeast).
The site is 35 km southwest of the city of Uşak (population 173,000) near the village of Gümüşkol. It sits approximately 1,000 metres above sea level in gently rolling hills.
Other economic activity in the area is a mixture of subsistence farming and grazing. A 5.3 km access road connects the site to the highway between Ulubey and Eşme.
Employees are mostly from the region.
Supplies and services are accessed from the city of Uşak. The site is serviced by a water well field with a 13 km water pipeline, and a 25 km power transmission line.
Climate
The area has a temperate climate. The average annual rainfall of 425 mm, occurs mostly during the winter months.
Operations
As of the date of this AIF, Kişladağ has been operating for nearly six years. Commercial production was temporarily interrupted from August 2007 to March 2008. See litigation, below, for more information.
Kişladağ is a large tonnage, low grade operation. The ore is amenable to heap leach and, while recoveries are lower than they would be if conventional carbon-in-leach was used, this is the most efficient method for treatment of the ore.
The open pit is mined using a standard drill and blast, truck and shovel mining process. The mine and the crusher operate 24 hours a day, seven days a week. A Turkish mining contractor provides ancillary services such as hauling run of mine ore to the leach pad.
Ore is processed in a standard heap leach facility using the following process:
● | crushing and screening in a three-stage plant |
● | transporting the crushed ore on two overland conveyors, and placing it on the heap leach pad using a radial stacker. The heap leach pad has a two-part liner system consisting of a layer of compacted low permeability clay soil, and a 2 mm thick high density polyethylene/low density polyethylene (HPDE/LDPE) synthetic liner. The designed stack height is 60 metres, placed in 10 metre high lifts |
● | leaching the crushed ore using a diluted cyanide solution applied by drip emitters |
● | recovering the gold in a carbon adsorption facility (ADR plant) that uses a standard Zadra process including pressure stripping, electro winning and smelting. |
The final product is a gold doré bar which can be processed to 99.999% purity in domestic or offshore refineries.
2011 Annual information form 17
The crushing and screening plant was upgraded in 2011 when new equipment was installed to allow an increase of throughput to 12.5 million tonnes per year. The expanded plant was commissioned in Q1 2011 and has performed above expectation.
During 2011 Eldorado announced the results of the Kişladağ Expansion Study. This study envisions the expansion of the crushing and screening plant with the installation of a parallel process circuit to handle an additional 12.5 million tonnes of ore per year. This new plant will also include three stages of crushing and screening. Scalping of fines from the ore will be incorporated in the new circuit using a similar design to the recent changes incorporated in the Phase III expansion of the existing circuit. A stand-alone overland conveying and stacking system will be installed to transport ore to an expanded leach pad. Additional capacity for solution processing and gold recovery will require construction of a new ADR plant and corresponding process ponds. Low grade ROM ore will be trucked directly from the mine to a dedicated leach pad. Metallurgical recoveries of 66% for crushed ore and 40% for ROM ore have been used and reflect operating results and metallurgical test work to date.
The current truck and shovel fleet will continue to be utilized through the fleet’s expected operating life. In addition, a fleet of larger trucks and loading equipment will be introduced during the expansion phase. This larger equipment will be equipped for electric operation to reduce operating costs. Quotations have been received from various suppliers of selected equipment to establish the overall capital cost of the mine fleet. This has included costing of support equipment and installation of a trolley assist distribution system for truck haulage.
Life of Mine Production and cost estimates
● | production: In 2011, 12.4 million tonnes of ore were placed on the pad. The expansion is expected to be operational in Q3 2014 and the expansion anticipates a crushed ore production of 25 Mtpa along with approximately 8 Mtpa of ROM ore also placed on the leach pads. |
● | gold production: 450,000 ounces per year for the remaining life of the mine. This includes 2012 and 2013 at 240,000 to 300,000 ounces while the expansion is being completed. |
● | cash operating cost: Life of mine cash costs are expected to be between $430 and $450 per ounce. |
Forecast gold production for 2012 is 285,000 to 295,000 ounces at a cash cost of $385 to $395 per ounce. Capital costs for 2012 are expected to be $175 million, most of which is to be used for mining equipment and infrastructure associated with the expansion.
Corporate tax for businesses in Turkey is currently 20%.
Production taxes in Turkey are assessed at 2% of gold revenues net of processing and selling costs.
Unit costs are expected to increase as the pit deepens. We expect the cost for processing and mine support to remain constant for the rest of the mine life, except in response to changes in costs that affect the entire gold mining industry, such as the cost of fuel and reagents, the cost of labour, exchange rates and inflation.
Environment
The environmental impact assessment study was submitted to the Ministry of Environment and Urbanization in January 2003, and the environmental positive certificate was issued in June of that year.
The environmental impact assessment identified several socio-economic effects of mine development, and identified measures that can be used to avoid or minimize potential environmental impacts.
An environmental monitoring program was implemented in 2005 that monitors air quality, surface water and groundwater, and provides reports to the relevant government agencies. The program also monitors noise and blast vibration, and the storage and disposal of waste and hazardous waste.
A mine reclamation plan was submitted in August 2008.
18 Eldorado Gold Corporation
Site remediation began in 2007, re-establishing tree cover in certain areas of the project site and studying cover system designs for capping the leach pad and rock dumps. This work has been supported by an investigation of the different plant, shrub and tree species suitable for local propagation, which we’re carrying out in our greenhouse. This work will be ongoing over the life of the mine.
In 2010, an engineered store and release capping system was placed on a limited area of the dump, as part of the annual rock dump reclamation activities.
At the end of 2011, another EIA was being prepared for submission in 2012. This EIA will cover the expanded operation allowing the treatment of 25 Mtpa through the crushing circuit.
Exploration
Tüprag discovered the Kişladağ deposit in the late 1990’s during a regional grassroots exploration program focusing on Late Cretaceous to Tertiary volcanic centres in western Turkey. It selected the prospect area on the basis of Landsat-5 images that had been processed to enhance areas of clay and iron alteration, followed by regional stream sediment and soil sampling programs. Preliminary soil sampling programs identified a broad 50 ppb Au anomaly within a poorly exposed area now known to directly overlie the porphyry deposit.
Early exploration of the deposit area included excavation of trenches to better characterize the soil anomaly, and ground geophysical surveys including IP-resistivity, magnetics, and radiometrics.
To date, there have been over 128,200 metres of diamond core and reverse circulation drilling at the Kişladağ project. Most of this has focused on resource definition drilling of the known deposit and exploration drilling in nearby areas. We have completed detailed geological mapping of the deposit and surrounding region, and definition and modeling of alteration zonation in the deposit area.
In 2011, our exploration program included over 10,000 metres of diamond drilling focused on condemnation work in areas of planned additional leach pad and waste rock dump sites. We also executed geophysical programs (IP) and soil geochemical surveys northeast and west of the Kişladağ deposit. In 2012 we will drill test key geophysical anomalies and carry out additional geophysical programs further to the west and north of the deposit.
Geology and mineralization
Geological setting
Kişladağ is a porphyry-style gold deposit located in one of several mid- to late-Tertiary volcanic complexes in western Turkey.
The deposit is centred on a series of overlapping Miocene sub-volcanic alkalic porphyry intrusions of quartz syenite to quartz monzonite composition. These intrusions and broadly coeval volcaniclastic rocks formed within and overlying a basement of schist and gneiss along the northeast margin of an uplifted terrane known as the Menderes Massif.
We have identified four major phases of the intrusive system, based on the intensity of alteration and mineralization, cross-cutting relationships and textural differences. These are listed from oldest to youngest and all are similar in composition:
● | Intrusion 1 has a slightly elliptical shape measuring approximately 800 metres across in plan view, and is cut by the younger intrusions |
● | Intrusion 2a is restricted to the southeast portion of the deposit area along the margin of Intrusion 1, and forms a roughly vertical cylinder body approximately 250 to 300 metres across |
● | Intrusion 2 occurs as two separate stocks each approximately 150 to 200 metres across, one in the centre of the deposit in the core of Intrusion 1, and the other on the northwestern margin of intrusion |
● | Intrusion 3 forms a semi-cylindrical stock near the centre of Intrusion 1, and extends westward into an elongate, steeply dipping to vertical dyke striking east-west |
Contacts between the intrusions are defined by chilled margins, and older intrusive units commonly occur as xenoliths in younger units.
2011 Annual information form 19
The mineralized intrusions at Kişladağ are enclosed within lithologically varied, volcanic and volcaniclastic strata. These strata dip outward from the deposit core, and display rapid facies changes from massive lavas and coarse poorly stratified units proximal to the porphyry centre, to finer well-stratified volcaniclastic strata interfingering with lacustrian sedimentary rocks in surrounding coeval sedimentary basins.
There has been relatively little structural modification to the deposit and surrounding Tertiary rocks. Lithologic contacts are primarily intrusive or depositional, with no documented major fault offsets. The deposit and adjacent rocks do, however, contain a high density of joints and low-displacement brittle fractures. Most of these are only a few metres to a few tens of metres in length, and have negligible displacement.
Alteration consists of a potassic core with K-feldspar, biotite, pyrite and quartz plus or minus magnetite, overprinted at higher levels and along the margins by an argillic zone, characterized by clay, sericite and chlorite. These zones are partially overlapped by an advanced argillic lithocap, and by an outer quartz and tourmaline zone.
Mineralization
Gold mineralization at Kişladağ occurs within zones of sulphide and quartz stockworks, and disseminated to fracture controlled sulphides. Pyrite is the dominant sulphide mineral, averaging around 4% in the primary mineralized zone, with trace amounts of molybdenum, zinc, lead, and copper. Highest gold grades occur in Intrusion 1, in multiphase quartz sulphide stockworks and zones of mottled to pervasive silicification. Intrusions 2 and 2a have economic gold values, albeit lower than in Intrusion 1, whereas grades in Intrusion 3 are negligible.
Oxidation extends to a depth of 30 to 80 metres on the southern side of the deposit, and 20 to 50 metres on the northern side of the deposit. Limonite and geothite are the most abundant oxide minerals. There is no supergene enrichment within the oxidized zone.
Drilling
Exploration drilling was completed at Kişladağ in several drilling campaigns between 1998 and 2011, with about 65% of the drilling during the period 2007 to 2010. Approximately 96,600 metres of diamond drilling, and 31,600 metres of reverse circulation drilling have been completed. All diamond drilling was done with wire line core rigs of mostly HQ size (63.5mm core diameter). Drillers placed drill core into wooden core boxes, each holding about four metres of core.
Project geologists systematically collected geological and geotechnical data from the core, and photo-graphed all core (wet) before sampling. Specific gravity measurements were obtained approximately every five metres.
The entire length of each core was cut in half with a diamond saw. One half was submitted for assay and one half retained for reference on site. Core recovery in the mineralized units was excellent, usually between 95% and 100%.
Sampling and analysis
Core samples are prepared at our preparation facility in Çanakkale in northwestern Turkey by inserting a Standard Reference Material (SRM), a duplicate and a blank sample into the sample stream at every eighth sample.
The samples were then shipped to ALS Chemex Analytical Laboratory in North Vancouver. The samples were assayed for gold by 30 g fire assay with an atomic absorption finish, and for other elements using fusion digestion and inductively coupled plasma spectroscopy (ICP) analysis.
Data verification
A review of the entire drillhole database since production started in 2006 has been done, and checked against the original assay certificates and survey data. Any discrepancies have been corrected and incorporated into our resource database. The mined portions of the resource model have been reconciled to production and agreement was excellent.
In our opinion, the Kişladağ deposit assay database is accurate and precise enough to estimate resources.

Technical report
The information in this AIF is partly based on the scientific and technical data in the Kişladağ technical report: Technical Report for Kişladağ Gold Mine, Turkey, by Stephen Juras, Ph.D., P. Geo.; Richard Miller, P. Eng.; and Paul Skayman, MAusIMM, all of Eldorado and qualified persons under NI 43-101.
The report is dated March 15, 2010, and effective January 2010. It’s available on SEDAR (www.sedar.com). There are a number of other technical reports on Kişladağ, also available on SEDAR.
Litigation
Litigation by certain third parties was brought against Tüprag and the Turkish Ministry of the Environment and Forests. The parties were seeking to cancel the positive environmental certificate for Kisladag on the basis of alleged threats to the environment and deficiencies in the environmental impact assessment.
In 2007, a lower administrative court ruled in our favour. The plaintiff appealed that decision and on July 19, 2007, the Sixth Department of Council of State ordered the mine to be shut down pending a decision on the case.
We shut the mining operations down on August 18, 2007, except for activities approved by the Turkish authorities related to sound environmental practices. The mine remained closed for the rest of that year.
On February 6, 2008, the Sixth Department of the High Administrative Court in Ankara, decided that the expert reports prepared for the Lower Administrative Court were not sufficient to make either a positive or negative decision on the merits of the case, and referred the matter for rehearing before the Lower Administrative Court.
On February 28, 2008, the Ministry of Environment and Forestry and Tüprag (as co-defendant) filed an appeal requesting that the court reconsider this decision and rule on the merits of the case. This appeal was denied. The matter was then referred to the Lower Administrative Court, which named an expert panel to review the environmental impact assessment and prepare a report.
On March 6, 2008, we reopened the mine and resumed production.
On October 13, 2010 the lower Administrative court issued a decision in the case that was unanimously in favour of the project. The plaintiff appealed the decision to the High Administrative Court in Ankara, where the file was reviewed. On December 7, 2011 The High Administrative Court issued its decision in favour of the project.
We are confident in both the methodology of the EIA and Tüprag's compliance with all procedural steps taken to obtain the environmental positive certificate.

About the property
Efemçukuru is in Izmir Province near the coast of western Turkey, about 20 km from Izmir, the provincial capital.
The site is 2 km north of the village of Efemçukuru (population approximately 500). It sits approximately 580 to 720 metres above sea level in hilly terrain. Vegetation is mainly mature pine trees with sparse undergrowth covering the hillsides.
Economic activity in the area is a mixture of subsistence farming and grazing. We mainly access supplies and services from the city of Izmir. Several paved and unpaved roads connect the village with other local population centres.
Employees are mostly drawn from the local region.
Power has been provided by a dedicated transmission line from the Urla substation approximately 20 km away. Mine infrastructure includes administration buildings, a concentrator, a filtration plant; tailings and waste rock impound areas. Concentrate is being treated at Kişladağ.
Climate
The area has hot and dry summers and warm and rainy winters with limited snowfall. Temperatures range between 30ºC in summer and 0ºC in winter with an annual average of approximately 17ºC. Average annual precipitation is 750 mm.
Operations
Efemçukuru is a high grade underground deposit with the gold occurring as free gold closely associated with sulphides. The ore is mined using conventional mechanized cut and fill along with some opportunity for longhole mining methods.
The ore is processed through a milling circuit followed by flotation to produce a concentrate and a gravity circuit. The gravity concentrate is refined to doré on site. As part of our operating agreement, we transport the flotation concentrate to Kişladağ, where it is being treated at a dedicated cyanide leach plant. The flotation tailings are filtered and either placed back underground as paste fill or placed in a lined tailings facility.

Environment
The environmental impact assessment study (EIA) was submitted to the Ministry of Environment and Urbanization in 2005, and the environmental positive certificate was issued in September of that year.
The environmental impact assessment identified several socio-economic effects of mine development, and identified measures that can be used to avoid or minimize potential environmental impacts.
An environmental monitoring program has been ongoing since 2005. The program includes regular monitoring of air quality, surface water and groundwater quality and provides reports to the relevant government agencies. Since the beginning of construction at the site, the program has also monitored noise and blast vibration, and the storage and disposal of waste and hazardous waste.
Site remediation was initiated in 2011 following completion of construction with the removal of the temporary construction site facilities and reclamation of the area for agricultural use. The rock dump will be prepared for reclamation as well with all final slope faces covered and seeded. Concurrent reclamation will be carried out as outlined in the mine reclamation plan, which formed part of the EIA process.
24 Eldorado Gold Corporation
Exploration
Shallow pits and underground workings along the auriferous veins, now overgrown by mature stands of forest, indicate that mining activity at Efemçukuru dates back at least several centuries.
Modern exploration began in 1992, when Tüprag recognized the exploration potential of the area while conducting reconnaissance work in western Turkey. Between 1992 and 1996, Tüprag conducted ground magnetic surveys, rock chip and soil sampling, geological mapping and a 6,000 metre diamond drilling program focusing primarily on the Kestane Beleni vein. This work identified high-grade gold mineralization in three separate zones: the south ore shoot, the middle ore shoot and the north ore shoot.
Infill drilling in 1997 and 1998 provided an initial resource estimate for the south and middle ore shoots, and a prefeasibility study was completed in 1999. Additional drilling programs from 2006 to 2010 with stepouts to deeper levels and along strike, significantly increased the resources estimate and provided a resource estimate for the north ore shoot. Drilling in 2011 focused on a new zone along strike from the north ore shoot, referred to as the Northwest Extension, and on the nearby Kokarpinar Vein.
The Kokarpinar vein is parallel to and east of the Kestane Beleni vein. We have drilled widely spaced exploration holes and obtained potentially economic grades from both surface samples and drillhole intercepts. Drilling to date does not support a resource estimate.
Soil and rock chip geochemical survey programs have been carried out as well as detailed geological mapping. The soil geochemistry surveys have identified several zones with multi-element anomalies. These anomalies are especially strong over the Kestane Beleni vein and the central part of the Kokarpinar vein.
We plan to continue exploring the Kestane Beleni vein at depth and along strike, as well as the subparallel Kokarpinar vein.
Geology and mineralization
Geological setting
The Efemçukuru epithermal vein deposit is at the western end of the Izmir-Ankara Suture Zone, a major regional structure that extends northeast and then east from Izmir for almost 800 km.
The deposit area is underlain by an Upper Cretaceous to Paleocene volcano-sedimentary sequence that has been regionally deformed and metamorphosed to greenschist facies. Adjacent to the mineralized veins, this sequence is dominated by phyllitic metasedimentary rocks, which have been subjected to a moderate to strong hornfels overprint in part of the deposit area. Numerous felsic (rhyolitic) dykes that predate the mineralized veins cut the phyllite sequence. These felsic dykes have steep dips, occur in a number of strike orientations, and aside from minor late faults, have not been significantly deformed.
Minor variably oriented faults cut the phyllite sequence, but none have significant displacement. The most continuous faults mapped to date coincide with the mineralized veins, and appear to have controlled vein emplacement.
Mineralization
Intermediate sulphidation mineralization at Efemçukuru is contained within the Kestane Beleni and Kokarpinar veins. The current resources and reserves are contained only in the Kestane Beleni vein. Both veins strike northwesterly (320°-340°), dip 60°E to 70°E, and can be traced on surface for strike lengths of over a kilometre. The veins commonly have faults with post-mineral movement along either hangingwall or footwall contacts, or within the veins themselves.
The Kestane Beleni vein’s three ore shoots (south, middle and north) differ slightly in strike and dip orientation, but the vein and the fault zone is continuous between them. All three are infilled by a combination of multi-stage breccias and layered veins with crustiform and colloform banded textures. Gangue minerals are dominated by quartz, rhodonite and rhodochrosite. Associated sulphides include pyrite, pyrrhotite, chalcopyrite, sphalerite and galena, which are oxidized at shallow levels. Most of the gold is very fine (2.5 to 50 microns), occurring as free grains in quartz and carbonate, and as inclusions in sulphide minerals. Lower grade mineralized stockworks occur peripheral to the ore shoots, and are most strongly developed in hangingwall rocks.
2011 Annual information form 25
Drilling
Drilling campaigns were conducted between 1992 and 1997, and from August 2006 to 2011. To date 285 core holes have been drilled totaling 47,500 metres, and 59 reverse-circulation holes totaling 5,000 metres.
All diamond drilling was done with wire line core rigs of mostly HQ size (63.5mm). Drillers placed the core into wooden core boxes. Each box held about four metres of core.
Geological and geotechnical data was collected from the core, and photographed (wet) before sampling. Core recovery in the mineralized units was very good.
The core library is kept in storage facilities near the site.
Sampling and analysis
A five foot or ten foot single tube core barrel is used to collect samples. Sample intervals from 0.1 metres to 1.6 metres were selected by the geologist and marked in the core boxes. We then cut individual samples using a diamond rock saw.
After initial crushing, each sample was split to approximately one kilogram, and then pulverized and split again into two 200 g pulps. One of these was shipped to the analytical laboratory and the other, with the approximately one kilogram of pulp reject, was put into storage.
The core samples were prepared at our preparation facility in Çanakkale in northwestern Turkey by inserting a Standard Reference Material (SRM), a duplicate and a blank sample into the sample stream at every eighth sample.
Samples were shipped to ALS Chemex Analytical Laboratory in North Vancouver. These were assayed for gold by 30 g fire assay with an atomic absorption finish (with a gravimetric finish re-assay for samples returning initial values greater than 8 g/t), and for other elements using fusion digestion and inductively coupled plasma spectroscopy (ICP) analysis.
Data verification
The database used to estimate the 2009 mineral resource was checked against the original source data. We checked survey and assay data and corrected any discrepancies before entering them into the resource database. Newer data entered directly into the database was also periodically compared to original electronic certificates (assays), down hole measurements and collar survey data.
In our opinion, the Efemçukuru deposit assay database is accurate and precise enough to estimate resources.
Technical report
The information in this AIF is partly based on the scientific and technical data in the Efemçukuru technical report: Technical Report on the Efemçukuru Project, Scott Cowie, BE (Mining), LLB, MAusIMM, Tetra Tech Australia Pty. Ltd. and Stephen Juras, Ph.D., P. Geo., qualified persons under NI 43-101.
The report is dated August 17, 2007 and is available on SEDAR (www.sedar.com).
Litigation
In 2004, certain third parties filed litigation against Tüprag and the Ministry of Energy and Natural Resources. The parties are seeking to cancel the mineral license for Efemçukuru on the basis of an alleged threat to the water quality in the local catchment area.
Turkey's Lower Administrative Court issued a negative decision, delaying the start of mining activities at Efemçukuru. The High Administrative Court overturned the decision in 2005, referred the case back to the Lower Administrative Court, and our mining license was re-issued.
The Lower Administrative Court formed a new expert committee to review the case. The majority of experts were in favour of the project and on June 15, 2007, the court ruled unanimously in favour of the project.

The decision was appealed to the High Administrative Court, and the decision was overturned on March 31, 2008. Tüprag appealed this decision. On March 10, 2009, the appeal was refused, and the case referred back to the Lower Administrative Court.
The lower court formed a new expert committee to review the case and on June 2, 2011, the Court unanimously ruled in favour of the project. The plaintiffs have exercised their right to appeal the case to the 8th department of the High Administrative Court where the case is now under consideration.
On January 26, 2009, the High Administrative Court delivered a positive decision in a case brought by certain third parties seeking to cancel the Environmental Positive Certificate for Efemçukuru issued by the Ministry of Energy and Natural Resources. The unsuccessful litigants have appealed this decision to the High Administrative Court requesting that its decision be reconsidered, which decision is pending.
We believe that chances of a reversal are very low. We are confident in both the methodology of the environmental assessment report and Tüprag's compliance with all procedural steps taken to obtain the Environmental Positive Certificate.
On August 18, 2011, certain parties filed litigation against the "Izmir Province Special Administration", seeking to cancel the "Trial Operation Permit" for Efemçukuru on the basis that the Efemçukuru Mining License and the Environmental Positive Opinion are unlawful. Tüprag has become a co-defendant in this case. The lower court is processing the case and is expected to name an expert committee to review the file.
We believe that we will successfully defend this litigation. If we do not succeed, our ability to operate Efemçukuru may be adversely affected, which may adversely affect our production and revenue.

Accrued royalties are transferred quarterly, directly to accounts Qinghai and Dachaidan have designated, as long as the related tax authorities approve. We paid approximately $8.2 million in royalties in 2011 related to Tanjianshan. |
About the property
Tanjianshan is in Qinghai Province in northwest China, 80 km northwest of Dachaidan in the Haixi Prefecture. Qinghai is a relatively large province with a population of approximately 5.3 million.
The nearest centres are Dunhuang, Gansu Province (265 km to the north by road) and Ge’ermu (260 km to the south by road).
The site is in the rugged Saishiteng Mountains, which have 45° to 50° slopes. The camp and mill sit 3,200 metres above sea level. The main resource is between 3,300 and 3,550 metres above sea level. There is almost no vegetation in the area.
A main highway between Dunhuang, Ge’ermu and Dachaidan passes within 12 km of the plant site. The road has been recently upgraded, is in good condition and provides year-round access. There are regular flights from Xining, the provincial capital, to Ge’ermu throughout the year and frequent flights between Beijing and Dunhuang during tourist season.
The only permanent river in the area, the Aolao, is approximately two km to the east. Water is pumped to a tank close to the plant and used to supply water to the plant and the process water tank. The water is treated for drinking.
Climate
The area has a dry continental climate with low rainfall, high evaporation and generally clear skies. Winters are long and summers short, with a large daily variance in temperature.
The average annual temperature is 1.6ºC and average annual rainfall is 87 mm. The temperature ranges from a high of 21ºC (in July and August) to a low of -15ºC (in January). Rainfall is highest in June and July, at 40 mm. There is little or no precipitation in November, December and January.
2011 Annual information form 31
The highest temperature on record is 29.9ºC on July 15, 1971 and the lowest is -32.3ºC on January 18, 1973. Winds are frequent and strong from the west and northwest averaging 8.6 km/h and peaking at 70 km/h.
Operations
The deposits are mined using a conventional open pit process carried out by a mining contractor. Mining at the Qinlongtan pit terminated in 2009. The ore is processed differently, depending on which pit it comes from. Qinlongtan ore was primarily free-milling with a small sulphide component that contained gold. Jinlonggou ore is predominantly refractory and requires an oxidation step (roasting). Roasting was selected over other alternatives mainly because of cost and because it is a common technology in China for treating refractory ores.
● | ore is crushed in a single stage crushing circuit and transported to a mill feed bin/stockpile, and then fed through a single stage SAG mill |
● | material from the Qinlongtan deposit was fed through a conventional carbon-in-leach circuit, the tailings were floated and the sulphide material removed for further treatment |
● | material from the Jinlonggou deposit is fed through a flotation circuit and then dewatered. The flotation tails are then treated through a conventional carbon-in-leach circuit |
● | the flotation concentrates are blended for an optimal sulphur grade and then fed to a two-stage roasting circuit |
● | the calcine product from the roaster is reground to break down agglomerates, and then leached in a carbon-in-leach circuit |
● | the tailings from the carbon-in-leach circuit are treated through a detoxification circuit to remove cyanide and to precipitate the remaining arsenic into a stable compound, and placed in the tailings management facility |
● | off-gas from the roaster passes through a cooling/cleaning circuit and an acid plant and the recovered sulphuric acid is sold |
● | the gold is recovered in a carbon adsorption facility (ADR plant) that uses a standard Zadra process including pressure stripping, electro winning and smelting |
The final product is a gold doré bar suitable for processing to 99.999% purity in domestic or offshore refineries.
The tailings management facility is a hillside tailings impoundment about one kilometre downstream from the plant. It has a maximum height of about 40 metres and uses a combination of downstream and centreline construction to minimize risk. The tailings dam is lined with an HDPE liner. The facility is designed to be nil discharge: all free water is returned to the treatment plant during operation.
Life of Mine Production and cost estimates
● | production: 1 million tonnes per year, at an average of 2,700 tonnes milled per day |
● | gold doré average of 110,000 ounces per year at a metallurgical recovery rate of 80.4% |
● | cash operating cost: $455 per ounce |
Forecast production for 2012 is 100,000 to 110,000 ounces at $445 - $460 an ounce. Capital costs for 2012 are expected to be $10 million.
The cost for mining is expected to increase slightly as the Jinlonggou pit deepens and mining of the 323 pit starts.
The cost for processing and mine support is expected to remain constant for the rest of the mine life, except in response to changes in the costs of inputs that affect the entire gold mining industry including, among other things diesel and reagents, labour, exchange rates and inflation.
Environment
SGS completed a draft environmental impact assessment for Tanjianshan in July 2005. BGRIMM completed an official Chinese version, and it was approved in April 2007. Tanjianshan is in a remote desert region, so it does not have the same number of environmental issues that sites in more arable parts of the country may face. There is very little wildlife or vegetation, and no permanent agricultural enterprises. The biggest issues are land use, water use from the nearby Aolao River and process
32 Eldorado Gold Corporation
discharges of sulfur dioxide and carbon dioxide gas, domestic sewage and tailings. Land that is disturbed in the process of gold mining must be purchased or leased from the government depending on effects to the land.
The EIA gives us the right to source all process and domestic water from the Aolao River. We built a small pond to facilitate water recovery, and were required to purchase the area of grassland it disturbed.
The gas scrubbing system that treats off-gas from the roaster meets strict SO2 discharge requirements, and we have a monitoring system installed at the site. Our current output is approximately 149mg/N.m3, well below recent environmental target reviews, which capped total SO2 discharge at 400mg/N.m3. The plant emission limit is 960mg/N.m3. Similar restrictions apply for CO2 emissions.
Water quality on the site is strictly controlled. The only discharge stream is treated sewage, which is discharged as class I water (the general discharge standard for sewage water). This is cleaner than the water in the river upstream of Tanjianshan site, which is class III (environmental quality standards for surface water). Excess water from the tailings dam pond is evaporated during the summer with the help of water cannons and spray evaporators.
Golder Associates in Melbourne designed the tailings dam, and BGRIMM transcribed the detailed engineering drawings to meet Chinese standards. The dam design was formally accepted in 2008, and final tailings accumulation RL is 3199 metres above sea level and 40 metres high. The dam uses a combination of downstream and centreline construction. It is double lined for zero permeability: first with a geo-membrane and then by 1.0 mm HDPE solid welded plastic. We have an ongoing water monitoring program upstream and downstream from the site, and all results are within required limits.
Exploration
Qinghai discovered gold at Jinlonggou during uranium exploration in 1989.Systematic soil and rock chip sampling and geological mapping over the exploration licenses and surrounding area, subsequently led to the discovery of high grade gold mineralization at Qinlongtan. At Jinlonggou, the Qinghai team generated exploration data in 29 surface drilled core holes, underground development on three levels, and extensive surface sampling in trenches, shallow pits or shafts on section lines 30 metres apart.
Subsequent exploration programs at Tanjianshan were completed by Sino Gold (1999 – 2003), Afcan Mining (2003 – 2005) and Eldorado (2005 – present). These programs have included geological mapping, underground and surface sampling and reverse circulation and diamond core drilling at the Jinlonggou and Qinlongtan deposits and several prospects. Aside from the two main deposits, the most significant mineral occurrences defined by this drilling are the Xijingou and 323 deposits.
Recent exploration (2009 – 2011) has employed shallow, grid based RC drilling to sample bedrock beneath the broad covered areas between the Qinlongtan and Jinlonggou deposits. This drilling has led to the discovery of the 323 deposit, named after the discovery hole. The 323 deposit was drilled on sections spaced at 50 metres during the late 2009 and 2010 field seasons, culminating in an inferred resource announced in late 2010. Exploration of the deposit in 2011 focused on the infill drilling on sections spaced at 25 metres.
Geology and mineralization
Geological setting
The Tanjianshan project area is underlain mainly by Proterozoic rocks of the Wandonggou Group. These rocks include sequences of carbonaceous phyllite to schist, dolomitic and limestone carbonate units, and chloritic plus or minus amphibolitic phyllite to schist of probable metavolcanic origin. Voluminous gabbroic to dioritic dykes and sills intrude these stratified units.
Rocks throughout the project area have been subject to multiple phases of ductile deformation, overprinted by brittle faulting. There is moderate to strong foliation in most units, striking parallel to the regional northwesterly structural fabric. Folds are common at the outcrop scale, and less common at the map scale.
Mineralization
The Tanjianshan project area contains significant gold resources at the Jinlonggou deposit, the newly-discovered 323 deposit and at the previously mined Qinlongtan and Xijingou deposits. The style of mineralization, structural controls and host units vary between these deposits.
2011 Annual information form 33
At Qinlongtan, ore was mined from a planar zone 5 to 10 metres wide (14 metres at its widest) dipping 50-80º eastward. The zone was mined for approximately 600 metres along strike and over 300 metres down dip. Gold was hosted in distinctive white silty dolomite, usually associated with fine-grained pyrite and arsenopyrite. The mineralized zone is localized within and along the margins of a narrow brittle to brittle/ductile fault zone, which is subparallel to or shallowly inclined to lithologic layering in adjacent units. Just below the present pit bottom, this controlling fault zone and the mineralized zone bend to a subvertical orientation. High gold grades remain in the bottom of the pit, and have been encountered in drillholes beneath the pit floor.
At the Jinlonggou deposit, host rocks consist of both carbonaceous phyllite and intermediate composition dykes. The phyllitic host rocks are dark grey to black, and contain a well-developed foliation and common crenulations and small scale folds. Chiastolite porphyroblasts are abundant. There are two intrusive rock types, diorite and quartz-feldspar porphyry, within the limits of the mineralization, and the diorite hosts a significant portion of the ore at Jinlonggou. At shallow levels of the deposit, both intrusive rock units occur as steeply (60°- 70°) southwest dipping, southeast striking, thin dykes. At deeper levels, they form multiple sheeted, sub horizontal sills, and are volumetrically more significant.
The Jinlonggou deposit is roughly bowl-shaped, about 500 metres in diameter and extending up to 240 metres below surface. At shallow levels, the mineralized zones are moderately to steeply dipping tabular zones distributed in phyllite next to faults and fracture zones. At deeper levels, diorite and phyllite host gently dipping mineralized zones.
The 323 deposit occurs in a lithologic setting similar to that of the Qinlongtan deposit. Host rocks vary from a fine-grained dolomitic meta-siltstone to a meta-sandstone with fine grained disseminated and clotted pyrite, capped by carbonaceous phyllite. The high grade zones commonly contain a moderate to strong overprint of ankerite and dolomite. Mineralization occurs in at least three separate stratigraphically and structurally controlled lenses.
Drilling
Initial exploration by Qinghai in the 1990s included 29 surface drilled core holes. Since that time, Sino Gold, Afcan Mining, and Eldorado have all carried out resource definition drilling at the Jinlonggou, Qinlongtan and 323 deposits, and other exploration drilling in the Tanjianshan project area.
There were six drilling campaigns between 2003 and 2008 to support resource models for the Jinlonggou deposit. A total of 310 core holes were drilled totaling over 38,300 metres.
Drilling campaigns at Xijingou and the 323 deposit between 2006 and 2010 totaled 66 core holes covering 13,400 metres at Xijingou, and 162 core holes for over 29,700 metres at the 323 deposit. The 2011 drilling program included an additional 10,300 metres in 58 core holes.
All diamond drilling was done with wire line core rigs of mostly HQ size. Drillers placed each core into composite core boxes. Each box held about four metres of core.
Geological and geotechnical data were collected from the core, and it was photographed wet before sampling. The core was sampled by sawing it in half with a diamond saw. Core recovery in the mineralized units was very good.
The core is stored in storage facilities near the site.
Sampling and analysis
Samples collected during core drilling used either a 1.5 metre or a 3 metre single tube core barrel. Sample intervals from 0.2 metres to 2.0 metres were selected by the geologist and marked in the core boxes. Individual samples were then cut using a diamond rock saw. One-half of the sawn core was bagged and sent for preparation at Eldorado’s preparation facility at Tanjianshan. After initial crushing, the sample was split to retain approximately one kilogram for pulverization. After pulverizing, the sample was split again to create two 200 g pulps. One 200 g pulp was shipped to the analytical laboratory and the second 200 g pulp, together with the approximately one kilogram of pulp reject, was put into storage.
34 Eldorado Gold Corporation
A Standard Reference Material (SRM) sample, a duplicate sample and a blank sample were inserted into the sample stream at about every eighth sample prior to shipment to the ALS analytical laboratory in Guangzhou, China. All samples were assayed for gold by 30 or 50 g charge fire assay with an atomic absorption finish.
Data verification
The database supporting the TJS resource models was reviewed in detail. Checks were made to original data certificates with any discrepancies corrected prior to use in updates to the resource estimate.
Results to date have shown excellent agreement between Jinlonggou mined production and the Jinlonggou resource model (the model supporting all of the mineral reserves at TJS and most of its measured and indicated resources).
In our opinion, the resource databases for the Jinlonggou, Xijingou and 323 Zone deposits are sufficiently free of error to be adequate for estimation of the respective mineral resources.
These data are also, in our opinion, accurate and precise enough for resource estimation.

About the property
Jinfeng is in Guizhou Province in southern China, 180 km southwest of Guiyang, the provincial capital, and 68 km southeast of Zhenfeng County centre, in the Qianxinan Prefecture.
There are four administrative villages in the Jinfeng area: Bai Ni Tian, Shi Zhu, Tinshan and Niluo. Populations range from 500 to 1,200 people. The nearest large population centre is Lannigou village, which is approximately 1.6 km from the mine and 1.9 km from the flotation tailings storage facility.
The mine is connected to the provincial highways by an 84 km sealed “Class 4” access road built and maintained by the provincial government.
Water is pumped to the plant from the Luofan River through a 3 km pipeline.
Electrical power is supplied by a 42 km long, 110kV electric power line from Zhenfeng, which is connected to the provincial electrical grid. A 22 km feeder line from Ceheng was added on April 25, 2009 to double the power supply feed.
The Jinfeng site also has two tailings storage facilities, waste storage and a metallurgical plant onsite.
2011 Annual information form 37
Climate
Guizhou Province is in the subtropical monsoon zone, which has a humid climate with hot summers and mild winters. The mine is designed to operate all year, although seasonal heavy rainfall may interrupt open-pit mining for several days per year. The average annual rainfall is 1,200 mm, which falls primarily from May to August. The temperature ranges between 6°C and 30°C, with a yearly average of 19°C.
Operations
We are currently mining from both the open pit and the underground mine (where the material is too deep to be mined by open pit methods). In 2012, we plan to mine 350,000 tonnes of ore from the open pit and 520,000 tonnes from the underground mine. Concurrently, the open pit mine will mine 10 million tonnes of waste to prepare for the next stage and the underground mine will advance its capital developments in order to ramp up the future production. Any shortfall in mill throughput capacity will be made up from existing stockpiles.
We use a standard truck and shovel process for the open pit, blasting on 5 metre benches in the ore and on 10 metre benches for bulk waste. We have been digging ore and waste on 2.5 metre flitches since July 2010 to reduce mining dilution and ore loss, and to protect bench walls.
In the underground mine, we use a cut and fill method, with mining equipment designed for areas that can be as narrow as four metres wide. Mined areas are backfilled with crushed waste, tailings and cement.
The process plant is designed to optimize gold recovery and minimize the cost of production. The process includes primary crushing, SAG, ball milling, bulk flotation, thickening, BIOX® and neutralization, carbon-in-leach, AARL elution and tailings detoxification. Tailings from flotation and leaching are kept in separate storage facilities to prevent biocides from getting back into the process water circuit.
Jinfeng ore is refractory in nature, with most of the gold encapsulated in sulphide minerals, so the gold is not easily dissolved using a conventional carbon-in-leach circuit. The processing plant uses BIOX® technology, which treats the sulphide minerals and exposes the gold before carbon-in-leach (CIL) processing, and ensures recovery is economic. The process was selected as the most efficient oxidation and extraction method for this ore type. Roasting and pressure oxidation were also considered as alternative methods of treatment.
Plant capacity is 1.5 million tonnes of ore per year. Budgeted recovery for 2012 is 84%.
Life of Mine Production and cost estimates
● | production: 1.5 to 1.0 million tonnes (depending on open pit operation) per year |
● | gold doré: average of 120,000 to 165,000 ounces per year (depending on open pit operation) at a metallurgical recovery rate of 85% |
● | cash operating cost: $700 to $800 per ounce |
Mining of the open pit stopped in the second quarter 2011 pending completion of the acquisition of land required for a planned cutback. It is expected that the land purchase will be completed in 2012.
Forecast production for 2012 is 120,000-125,000 ounces at a cash operating cost of $675-693 an ounce. Capital costs in 2012 are expected to be $50 million.
We expect the unit cost for mining to increase as the percentage of production from the underground mine increases. The cost for processing and mine support is expected to remain constant for the rest of the mine life, except in response to changes in the costs of inputs that affect the entire gold mining industry including among other things: the cost of diesel and reagents, the cost of labour, exchange rates and inflation.
Environment
Jinfeng’s environmental impact assessment report was completed in July 2004 and approved by Guizhou Province Environmental Protection Bureau in September of that year. Guizhou Province issued the final environmental project approval in December 2008. The environment impact assessment report identified a number of environmental risks and defined a number of measures to avoid or minimize potential environmental impacts.
An environment management system covering water management, air management, general monitoring and waste management was developed for the mine operation. Jinfeng discharges 2,078 cubic metres per day of tailings wastewater from the carbon-in-leach circuit to Luofan River, and is required to keep the
38 Eldorado Gold Corporation
level of Weak Acid Dissociable (WAD) Cyanide tailings wastewater from carbon-in-leach circuit below 0.5ppm.
Before preproduction, the local environment around Jinfeng was investigated. An environment monitoring plan was developed in the production phase to address the potential impacts of the mine operation on air quality, noise, surface water and groundwater.
The local government approved a Rehabilitation Plan and a Mining Environment Comprehensive Treatment Report in 2009 (a regulatory requirement).
Jinfeng developed a surface remediation plan and began remediation in the construction phase, starting in 2006. As of the end of 2011, we had finished surface remediation of 130,000 m2, and stockpiled approximately 590,000 m3 of topsoil for further remediation. We will be collecting some soil from the Longtan hydroelectric dam project near Luofan River for use at Jinfeng.
Jinfeng has also built a nursery for seedling cultivation of some local plants and uses these seedlings in site remediation.
Jinfeng tailings have been shown to be net acid generating. The carbon-in-leach tailings are expected to have a residual sulphide content of about 0.5 to 1% (estimated acid generation potential of 15 to 30 kgH2SO4/tonne) with no neutralization buffering capacity since they have been acid leached. We have since decided to filter the carbon-in-leach tailings before placing them in the tailings dam. The carbon-in-leach tailings are placed by trucks, and spread and compacted by excavators and dozers. The placed tailings have no free water and will not generate leachate. We have also established a monitoring well network to monitor the groundwater chemistry under both the flotation and carbon-in-leach dams. The wells are sampled monthly and are showing no signs of reduced pH under the carbon-in-leach dam.
The small scale waste rock column tests have shown a propensity to leach arsenic. We have monitoring wells in place around the waste dump and have not noted elevated arsenic levels. We will continue to monitor the arsenic levels in the wells and if arsenic reaches an unacceptable level, remediation in the form of water treatment may be necessary.
Exploration
The Jinfeng deposit was discovered by the Guizhou 117 Brigade in the early 1980s during follow-up of regional stream sediment surveys, which identified strongly anomalous gold and arsenic values in the deposit area. Systematic subsequent exploration work included geological mapping, surface trenching, diamond drilling and excavation of a number of exploration adits.
After acquiring the project in 2001, Sino Gold completed detailed infill drilling of the deposit, and began reconnaissance exploration activities in the surrounding region.
Current exploration activities are focused on extending the known underground resource down-dip and down-plunge through underground and surface drilling, as well as identifying additional resources in satellite bodies near the surface.
Geology and mineralization
Geological setting
Jinfeng is in China’s Golden Triangle, on the southwest margin of the Precambrian Yangtze Craton. The Golden Triangle encompasses an area with more than 200 gold occurrences and deposits hosted within Paleozoic and lower Mesozoic carbonate and siliciclastic sedimentary rocks. The Jinfeng region has gone through several periods of both extensional and contractional deformation, resulting in complex faults and fold interference patterns.
The sedimentary succession near the Jinfeng deposit is Paleozoic limestone, overlain by Lower Triassic limestone and Middle Triassic turbiditic sedimentary rocks. The deposit is along the northeast margin of the Laizishan dome, a major feature formed at the intersection of northeast-striking and northwest-striking regional anticlines, and is hosted by Triassic calcareous sandstones and shales, mostly in and immediately adjacent to a series of interconnected major faults and fault zones (the F3, F2 and F6 faults).
2011 Annual information form 39
Mineralization
The orebody is a Carlin-like, sediment-hosted, structurally controlled gold deposit with some replacement style mineralization, contained within and adjacent to a series of intersecting faults. The mineralized zone is over 1200 metres in strike length, has a vertical extent of up to 1,100 metres and is typically 10 to 50 metres wide.
The deposit can be divided into three major domains, defined on the basis of controlling faults systems:
● | mineralized zones along the F3 fault, and where the F3 fault intersects with the F7 fault |
● | mineralized zones along the F2 fault |
● | mineralization on a number of narrow faults in the F6 fault zone in the Rongban portion of the deposit. |
Mineralization has been explored on the F3 and F7 faults to 1100 metres vertically below surface. Most of the mineralization is on the F3 fault. The ore includes disseminated pyrite, arsenical pyrite, and arsenopyrite, which replace the shale and sandstone of the Middle Triassic Xuman Formation in the fault zones and in the immediately adjacent wall rocks. Gold occurs in the rims of fine-grained pyrite and arsenopyrite grains and is very finely distributed through the deposit. Elevated mercury, arsenic, and antimony are associated with the gold.
Drilling
Data supporting the Jinfeng mineral resource is drawn from HQ and NQ diameter diamond drill holes drilled from surface locations and underground headings.
Since Sino Gold acquired the project in 2001, considerable infill drilling of the deposit and the reconnaissance exploration drilling in the surrounding region have been conducted. Since 2001, approximately 490 exploration drill holes, or 197,000 metres, have been drilled to delineate the resource and to test additional targets on the property. The deepest drilling intercepted strong gold mineralization and intense alteration at more than 1,000 metres in depth. In addition, about 680 infill drill holes, or 66,000 metres, were drilled for underground production purposes since 2008, when the underground mine operation started.
Another phase of exploration drilling began in 2010, drilling 567 holes totaling 20,500 metres, mainly from underground platforms. In 2011, an additional 16,200 metres of underground exploration drilling (60 drill holes) and 11,700 metres of surface exploration drilling (35 holes) were completed.
In 2012, 79 exploration drill holes, or 25,000 metres, are planned for both surface and underground to further delineate the orebodies and to test new targets. 110 infill drill holes, or 14,000 metres, are to be drilled in approximately a 10 by 20 metre pattern for production purposes.
In the future, there will be similar drilling programs as in 2012 in order to further delineate the deep resources, test new targets and infill-drill the deposit areas for ongoing productions.
Drillers placed the core into labeled plastic core trays at the drill rig, and marked them before they were brought to the core shed facilities. Geological and geotechnical data were collected from the core and transferred to the project drill database. Core recovery in the mineralized zones was very good, averaging 91%.
Sampling and analysis
Sample intervals averaging 1.0 metre were selected by the geologist and marked in the core boxes. These were then sawn in half with a diamond saw. One half was submitted for assay and one half retained for reference on site. Sample intervals from underground preproduction holes were sampled in their entirety.
After initial crushing, the samples were pulverized to pass minus 200 mesh. A 200 gm split was set aside for analysis. Prior to analysis, quality control samples, a Standard Reference Material (SRM), a duplicate sample and a blank sample were inserted into the sample stream at about every twenty-fifth sample.
Samples were analyzed by the Jinfeng mine laboratory using standard AAS-Graphite Furnace assaying after Aqua Regia digestion and hydrofluoric acid treatment to completely liberate all trace constituents from silicate mineral matrices. We also sent about 5% to 10% of the samples to the ALS facility in Guangzhou for third party quality monitoring.

Data verification
Monitoring of the control samples, using our quality assurance and quality control program, and the third party laboratory results, showed all data were in control during the preparation and analytical processes.
Another form of verification is the reconciliation to production of mined portions of the resource model. Results to date have shown very good agreement between mined and milled production and the long-term mineral resource model.
In our opinion, these observations demonstrate that the data gathered and measured for the purposes of estimating the gold grades at the Jinfeng gold mine are verified.
In our opinion, the Jinfeng deposit assay database is accurate and precise enough to support mineral resource estimation.

About the property
White Mountain is in Jilin Province in northeast China, 230 km southeast of Changchun.
The site is in the Longgamp Mountains about 8 km west of the city of Baishan. There are two topographic areas: the low mountain area and the valley basin. Vegetation is mainly natural secondary forest.
The site is 2 km from a Class 1 highway that connects Baishan and Changchun. Flights to many domestic and international cities are available from Changchun Longjia International Airport. There is a large labour pool in the area and both mechanical and electrical maintenance are provided locally.
There is plenty of surface water in the area, from the Diaoshuishe and Dabanshigouhe branches of the Huihe River and the Huijiang River. The Diaoshuishe branch is the main water source for the operation. The pipeline is buried to prevent freezing in the winter.
The mine is connected to the 66kV Jiangbei Electrical Substation approximately 4 km from the site.
The tailings storage facility is about 600 metres west of the site in a steep sided valley. The mill is situated where the Zhengjiangon Creek and the larger Zhenshumengoa River meet.
Climate
The area is in the north temperate climate zone. It has annual average precipitation of 350 to 1,000 mm, 60% of which falls from June to August. The temperature ranges from - 42.2 C to 36.5 C, with an annual average temperature of 4.6 C.
Operations
We use a sub-level open stoping mining method where the orebody is thicker than 10 metres and steeper than 55 degrees, and a benching method in narrower areas. The processing plant is a standard carbon-in-leach plant.
We have based the production schedule on metallurgical testing that identified two types of ore: non-refractory (approximately 90% of the ore) and refractory (approximately 10%). Recoveries are nominally 85% for non-refractory and 65% for refractory ore.
2011 Annual information form 43
Since the refractory component is a small percentage of the overall orebody we have chosen to use a standard carbon-in-leach plant. Because of the refractory component, recoveries can be variable based on where we are mining in any month. Late in 2011, a caustic pre-treatment process was commissioned to enhance recovering in sulfide ores. Initial results have been successful and this process is expected to raise overall recovery by 1% to 2% and in sulphide ores by 5 to 10%.
Life of Mine Production and cost estimates
● | production: 700,000 tonnes per year |
● | gold doré: 71,000 ounces per year at a metallurgical recovery rate of 80.3% |
● | cash operating cost: $530 per ounce |
Capital costs in 2011 were $17 million for underground development and infrastructure, processing upgrades and exploration. Capital costs for 2012 are expected to be $15 million.
Forecast production for 2012 is 75,000 to 80,000 ounces at a cash operating cost of $535 - $550 an ounce. The cost for processing and mine support is expected to remain constant for the rest of the mine life, except in response to changes in the costs of inputs that affect the entire gold mining industry including, among other things: the cost of diesel and reagents, the cost of labour, exchange rates and inflation.
Environment
White Mountain has had an exemplary environmental record and operates under high environmental standards and facility designs.
Extensive testing of nearby streams resulted from an event in 2009 in which a small group of farmers blocked our road, alleging pollution of water in a nearby creek. This testing confirmed no pollution. We now have the approval of the Environmental Protection Bureau to discharge treated water.
White Mountain has a good relationship with the surrounding community and local government. This is bolstered with our “Four Party Joint Office” consisting of the company, government, Jilin University, and Community representatives.
Exploration
The Chinese Provincial exploration brigade carried out preliminary exploration in the White Mountain area from the late 1990s until 2003, when Sino Gold acquired an interest in the project through a joint venture. Preliminary exploration work by the Chinese Brigade included geological mapping, soil geochemistry, trenching, and excavation of two adits and completion of three drillholes.
After the deposit was discovered in late 2004, Sino Gold drilled over 84,000 metres over a three year period. Recent exploration has focused on drilling stepout holes along strike and downdip on the main orebody. In addition, early-stage exploration programs comprising mapping, soil sampling, trenching, and drilling are ongoing on several nearby prospects with geological characteristics similar to the White Mountain deposit.
Geology and mineralization
Geological setting
The White Mountain deposit is located adjacent to a regional northeast-striking fault zone that separates Archean craton from a sequence of Phanerozoic sedimentary rocks. Gold mineralization is known to occur over at least a 6 km strike length of the fault zone, primarily hosted in the younger stratigraphic sequence.
Most of the White Mountain deposit occurs along a southeast dipping (40-50°) contact between marl and dolomite and overlying quartzites historically referred to as the F100 fault. This contact terminates updip against the northeast striking F120 fault which dips 70-80° to the southeast. It records significant movement and juxtaposes the hanging wall sequence against a sequence of folded shale and fine-grained sandstone in the footwall.
44 Eldorado Gold Corporation
The deposit is thickest and has highest grades where the controlling contact intersects the F102 fault, and within a few hundred metres downdip of this intersection. Mineralization extends over a strike length of approximately 1,400 metres, and to between 100 and 600 metres downdip from the intersection with F102.
Mineralization
Gold mineralization at White Mountain occurs within and adjacent to a silicified hematitic breccia zone and is associated with pyrite, hematite, and barite. The breccia is localized along the quartzite - dolomite contact, and the thickness of the strongly mineralized zone ranges between ten and twelve metres. The deposit remains open along strike to the northeast and at depth.
Drilling
The data supporting the mineral resources is drawn from diamond drill holes of NQ diameter, drilled from surface locations and underground headings. Surface drilling includes a total of 326 holes covering 106,570 metres, generally in a 40 by 50 metre grid over the deposit. Underground drilling includes a total of 749 holes covering 54,320 metres in a 15 by 10 metre pattern.
Drillers placed the core into labeled plastic core trays at the drill rig, and marked them before they were brought to the core shed facilities.
Geological and geotechnical data were collected from the core and transferred to the project drill database. Core recovery in the mineralized zones was higher than 95%.
Samples were selected at one metre intervals. The core was cut in half with a diamond saw. Half was sent for analysis and the other half returned to the core tray.
Surface core samples were dispatched to the sample preparation facilities operated by Geological Brigade 606 – Non-Ferrous Metallic and Geological Exploration Bureau of Jilin Province in Tonghua city. Underground samples were processed at the mine site sample preparation facility.
Sampling and analysis
After initial crushing, the samples were pulverized to pass minus 20 mesh. A 300 g sample was then pulverized to minus 200 mesh and poured into kraft bags. Core samples were prepared by inserting a Standard Reference Material (SRM), a duplicate sample and a blank sample into the sample stream at every twentieth sample.
Until 2010, all surface samples were analyzed at Northwest Non-ferrous Metals Geology Institute at Xi’an in Shaanxi province, where samples were assayed using standard AAS-Graphite Furnace assaying after Aqua Regia digestion and hydrofluoric acid treatment to completely liberate all trace constituents from silicate mineral matrices. Since 2010, we have sent the surface samples to the ALS analytical laboratory in Guangzhou, which used fire assaying methods. Underground samples are analyzed at site.
Data verification
Xi’an Lab analyses of resource and reserve drilling phases was reviewed and early analyses (2004 to 2006) found to be precise but variably accurate. However, much of the deposit covered by these older data has been re-drilled as part of ongoing underground grade control drilling. The underground data are supported by quality control and quality assurance samples which showed that all data were in control throughout the preparation and analytical processes. The same control was demonstrated for samples sent to ALS.
Another form of verification is the reconciliation to production of mined portions of the resource model. Results to date have shown good agreement between mined and milled production and the long-term mineral resource model.
In our opinion, these observations demonstrate that the data gathered and measured for the purposes of estimating the gold grades at the White Mountain gold mine are verified.

This area is known as EL53. |
Permits | The following permits are required: • project permit approval • mining license • forestry permit (tree removal) • gold operating permit |
Royalties | We are required to pay royalties to state and local authorities. We are negotiating the amounts and will finalize the arrangement after we receive all permits. |
About the property
Eastern Dragon is in Heilongjiang Province in northern China, approximately 425 km north of the provincial capital Harbin, and 45 km southeast of the town of Xunke. Xunke is 70 km from Heihe city, 118 km from Sunwu county town and 120 km from Yichin city in Wuyiling district.
There is road and rail access from Harbin to Sunwu and Yichin. A sealed highway just a few kilometres from the site connects Heihe to Xunke. There are flight connections between Heihe and Harbin and from Harbin to other cities in China, including Beijing.
The deposit is 200 to 280 metres above sea level, in an area of rolling hills that are farmed in the summer or dedicated to forestry. The lower lying areas are suitable sites for mine infrastructure, tailings and waste disposal, subject to government approval. An 8 km road from the highway to the project area passes through farmland and forested areas, and is unsealed over the last half.
There is a 35kV power substation 8 km from the site. Water can be sourced from the Kubin River, 1.2 km to the north of the deposit. Coal is available from the Heilongjiang Hegang coal mine. Basic building materials can be sourced from Heihe and other materials from Harbin.
Climate
The area has relatively long winters and short, hot summers. Average annual rainfall is 430 mm. It generally is covered in snow from mid-October to April.
Operations
Eastern Dragon will start out as a small open-pit mine, and then become an underground operation.
The proposed open pit has been designed to minimize land use, and we expect it to have enough volume to store all of the tailings from the underground operation.
A total of $24.3 million was spent on construction at the Eastern Dragon project in 2011. During the year site buildings were enclosed and major mechanical and electrical phases were completed. In November construction was suspended pending receipt of permitting required to complete development of the mine. This includes constructions of the tailings and storage facilities as well as the open pit and rock dump areas.
The contractor should begin development of the underground mine in July 2014, as long we receive the project permit. We expect construction and ramp-up to full production to take approximately two years: three months for portal work, fifteen months to develop the decline to 125 metres elevation at an advance rate of 60 metres per month, and three to six months for ore sill development and other preproduction activities.
48 Eldorado Gold Corporation
Underground ore production should begin at lower rates in July 2013, and reach peak production of 1,000 tonnes per day at the end of 2013. We have to mine two underground bench stopes concurrently, at a vertical advance rate of approximately 30 metres per year, to meet this production level.
The Eastern Dragon ore is high grade (7.71 g/t Au and 71 g/t Ag), and it is amenable to cyanide leach with high recoveries for both gold and silver. The process plant is designed to treat 450 tonnes of ore per day initially and will increase to 1,000 tonnes per day as part of a planned expansion.
We are using conventional equipment and processes:
● | run of mine ore is crushed in a two-stage crushing circuit and then milled in a single stage ball mill |
● | the ore is leached with cyanide and thickened |
● | the thickener overflow is fed to a carbon-in-column (CIC) circuit, which removes most of the silver from the circuit |
● | the thickener underflow is leached again with cyanide in a normal carbon-in-leach circuit. This, combined with the pre-leach and the CIC, ensures the highest possible recoveries of gold and silver. |
● | loaded carbon from the two circuits is then combined and eluted to recover the precious metals |
● | after we have recovered the gold and silver, the tailings from carbon-in-leach circuit are thickened. The overflow is recycled, and the underflow is forwarded to a cyanide destruction circuit and then dewatered using filter presses to produce a filter cake suitable for dry stock tailings disposal. During the first two years of operation, tailings will be impounded in an interim tailings dump. After open pit mining stops, these will be moved to the mine’s open pit. |
Life of Mine Production and cost estimates
● | production: 450 tonnes per day for 12 to 24 months, followed by 1,000 tonnes per day, or 360,000 tonnes per year thereafter. |
● | gold doré: 80,000 ounces per year at a metallurgical recovery rate of 90% |
● | silver: 580,000 ounces per year at a metallurgical recovery rate of 80% |
● | cash operating cost: $176 per ounce gold (after silver credits, calculated using a silver price of $35 per ounce) |
Forecast production for 2012 is 25,000 to 30,000 ounces at a cash operating cost of $65 – $80 an ounce. Capital costs for 2012 are expected to be $45 million.
Environment
We are developing environmental management programs and procedures, including environmental monitoring, tailings storage facility operation, site rehabilitation, water management and hydrocarbon management. Site rehabilitation will begin during the construction stage.
The local Land and Resource Bureau will require a mine closure bond as financial assurance. This will be returned in stages as rehabilitation is completed.
Exploration
The Eastern Dragon deposit was discovered in 1998, after the Heilongjiang 707 Brigade identified mineralized quartz vein float during a regional geological survey and 1:200,000 mapping program. Between 1999 and 2002, the 707 Brigade completed geological mapping, soil and stream sediment sampling programs, extensive trenching, gradient array resistivity and ground magnetic surveys, excavation of underground exploration adits and over 8,900 metres of diamond drilling. This work outlined an initial resource on the Lode 5 vein deposit, and identified several other vein targets in surrounding areas.
Recent exploration includes induced polarization and ground magnetic geophysical surveys in 2009 and 2010, as well as additional prospecting and sampling. Drilling in 2009 extended known mineralization 200 metres to the north and 75 metres to the south along strike. Assays confirmed that the northern extension contains several high-grade mineralized zones near the surface.
2011 Annual information form 49
Geology and mineralization
Geological setting
Eastern Dragon sits above a basement granitic intrusive complex, composed of medium grained granodiorite and adamellite of probable Triassic age. These are unconformably overlain by a Cretaceous volcanic, volcaniclastic and sedimentary sequence of intermediate to locally felsic composition. The northern part of the deposit underlies a post-mineralization sequence of weakly-consolidated Tertiary alluvial and colluvial sandstone and conglomerate up to 25 metres thick.
The epithermal veins at Eastern Dragon occur along roughly north-south striking, subvertical faults that cut and displace the basement rocks and overlying Cretaceous strata, but are overlapped by Tertiary sedimentary rocks. Displacement on these faults does not appear to be more than a few tens of metres.
Mineralization
Eastern Dragon is a low sulfidation, epithermal vein deposit. Most of the defined resource is confined to a single vein (Lode 5), that has been traced over a strike length of approximately one kilometre north-south. The mineralized part of Lode 5 averages around 6 metres wide, and is steeply dipping to subvertical.
The vein is infilled mainly with colloform and crustiform banded quartz, often pseudomorphing bladed calcite. Breccia textures are common. Paragenetically late quartz plus chlorite plus pyrite overprints the banded quartz veins, and is associated with lower gold grades. The veins are enveloped in a clay and sericite alteration zone, grading outward to chlorite alteration of matic minerals in host rock.
Drilling
The 707 Brigade completed 45 diamond drill holes totaling 8,903 m from 1998 to 2002.
In 2008, Sino Gold carried out several hundred check assays, including diamond drilling and channel sampling, to extend, infill and check the work done to date. Drilling completed by Sino Gold totals 133 holes covering 29,000 metres. All diamond drilling was done with diamond drill rigs of NQ to HQ size. Drill lines are from 25 to 50 metres apart. Drill holes are typically 30 to 50 metres apart, and are inclined to the east and west, from about 45 degrees to almost vertical.
Collars were located by detailed surveys. Down hole surveying was routinely done at 30 metre intervals and at the end of the hole, mostly using an Eastman down hole survey tool.
Drillers placed the core into recycled plastic core trays at the drill rig, and marked them before they were brought to the core shed facilities.
Geological and geotechnical data were collected from the core and transferred to the project drill database. All core was photographed before sampling.
Samples were selected at one metre intervals. The core was cut in half with a diamond saw. Half was sent for analysis and the other half returned to the core tray. Core recovery in barren and mineralized zones was higher than 95%.
We keep the core library in storage facilities on site.
Sampling and analysis
After initial crushing, each sample was pulverized to pass minus 200 mesh. About 80 g of the pulverized sample was sent to Intertek (Beijing) and SGS (Tianjin), and assayed for both gold and silver using fire assay with an atomic absorption finish.
Core samples were prepared by inserting a standard and duplicate control sample into the sample stream at every tenth sample. Blank samples were not inserted, although some standards used were of such low values that they were effectively blanks. A third party laboratory was used in all campaigns.
About 5 to 10% of the samples were sent to the ALS facility in Brisbane and later to the ALS facility in Guangzhou. Samples were analyzed by fire assaying methods.
The specific gravity was measured for 424 samples, using the weight difference in air and when submerged in water. The average specific gravity for Lode 5 was 2.55.
Metallurgical sampling test work has been carried out on three composite samples:
50 Eldorado Gold Corporation
● | one from surface trenches, carried out by 707 Brigade and tested at Changchun Gold Research Institute |
● | a mix of surface trenches and adit channel sampling, carried out by 707 Brigade and tested at the Jilin Gold Research Institute |
● | a mix of surface and adit samples plus selected drill core, carried out by Heihe and tested at Beijing General Research Institute for Mining and Metallurgy |
The two programs carried out by 707 Brigade included evaluating gold recovery by flotation, gravity and leaching, and included evaluation of carbon-in-leach, resin-in-pulp and leach/zinc cementation leaching options.
The more recent program by Heihe included leaching test work, evaluating a flotation/carbon-in-leach option and test work for partial recovery of precious metals from solution onto carbon using columns.
Standard analytical methods were used and duplicate tests were carried out for all major tests. Leach recoveries for gold from all three programs were higher than 94%.
Data verification
A review of earlier quality assurance and quality control data showed that samples from the 707 Brigade were in control during preparation and analytical processes. Data from the 2009 and 2010 drill campaigns and the third party laboratory check assays were also in control.
In our opinion, the Eastern Dragon deposit assay database is accurate and precise enough to estimate resources.
Litigation
There are currently no known material litigation matters or outstanding actions against Eastern Dragon or Heihe Rockmining Limited relating to Eastern Dragon.

Regional review
Brazil
We have a long history of operating in Brazil, dating back to 1996, when we acquired the Sao Bento Mine and other exploration assets from Gencor. We sold the Sao Bento Mine to AngloGold in 2008, but retained Sao Bento’s key management and exploration executives, who have since been responsible for discovering, developing and operating the Vila Nova Iron Ore Mine, advancing Tocantinzinho towards a feasibility study and construction decision, and evaluating new opportunities in the gold and mineral sectors of Brazil.
Properties
We currently have one operation and one development project in Brazil:
● | Vila Nova – iron ore mine |
● | Tocantinzinho – gold development project |
Other exploration
Our exploration programs in Brazil focus on our existing projects in the Tapajos region of Para state, and on project generation opportunities elsewhere in Brazil. In addition to the Tocantinzinho development project, we are presently exploring at our nearby Agua Branca and Piranhas projects.

About the property
The 1,475 hectare Vila Nova property sits 175 km west of Macapá, the capital of Amapá State, in northeastern Brazil. The majority of workers are drawn from the local region.
The site is mostly flat, with small slopes and dense vegetation. The nearby Vila Nova River, which flows through the property, is used for water supply.
To support mining, processing and transportation, maintenance shops, accommodations, water and electrical supply, crushing and screening facilities, a spiral circuit and a tailings dam have been built.
The tailings dam is made of compacted earth from the surrounding areas. The first phase of construction will support four years of operation. A second phase will raise the crest of the dam to contain all tailings generated during the mine’s nine year life.
Processed iron ore is sent by rail to the port for shipping. The Public Port CDSA is operated by the Santana Port Authority. A second private port is operated by Anglo Ferrous do Brazil. The two ports are on the north bank of the Amazon River, in the town of Santana, approximately 18 km upstream from Macapá. All shipments have been sent through the Anglo Ferrous port. There are no plans to use the public facility at this time.
Climate
The site is in a tropical rainforest region. Annual rainfall is 2,300 mm, and 85% of this falls in the rainy season (December to June). The annual temperature ranges from 230 C to 350 C. Relative humidity is 95%.
Operations
The Vila Nova Iron ore deposit is 5 - 40 metres thick and 1,800 metres along strike. The ore body is subvertical, with hanging and footwall made up of weathered schist. It is well-suited for open pit mining using small mine equipment.
The mine is a standard open pit that produces two products: lump ore and sinter fines. It uses hydraulic excavators and highway-type haul trucks with conventional rock boxes.
54 Eldorado Gold Corporation
Trial mining and processing was conducted in June 2010 to test plant performance and logistic systems. The initial monthly production rate for 2011 was 55,000 tonnes of run of mine ore, yielding 45,000 wet metric tonnes of finished product. Approximately 50 percent of this is lump ore and 50 percent sinter fines.
High grade phosphorus ore from the upper benches is stockpiled and later blended with low grade phosphorus ore. Waste rock is placed onto a dump 2.5 km from the pit. In 2011, the strip ratio was 3:2:1 and for 2012 the strip ratio is planned to be 7:1. During 2011, we had a contract with Anglo Ferrous to transport iron ore to Santana by railway, and provide ship loading in the Anglo Ferrous port. We completed eleven shipments of lump and sinter in 2011 and all material was sold on the spot market. Currently negotiations are underway for a five year contract with Anglo Ferrous. This longer contract is precipitated by the need to increase the rolling stock on the existing rail line. It is expected that this contract will be signed early in 2012.
Production and cost estimates
● | production of finished products: |
2012: 535,000 dry metric tonnes
2013: 535,000 dry metric tonnes
● | operating costs: approximately $75 per dry tonne of lump ore and sinter fines for the life of mine |
There is provision to increase the production rate at Villa Nova with modest capital requirements. However, at the end of 2011, the iron ore spot price was not supportive of such investment. This will be reviewed moving forward. Capex to date is $46.7 million.
The maximum general corporate tax rate in Brazil is 34%. Due to its location, however, Vila Nova qualifies for a reduced tax rate of 15.25%.
Environment
On July 29, 2011, Amapá State’s environmental agency granted transference of the operating environmental license which is valid for one year.
We have implemented an environmental sampling program to monitor the pH, oils and chemical elements in the water and effluent, to make sure the operation is not contaminating the adjacent water systems. Every four months, we send a report with the results to Amapa State’s SEMA Environmental Agency.
Once the mine is closed, we will re-vegetate the pit, tailings dam and the waste dump and plant regional trees.
Geology and mineralization
Geological setting
The deposit is a steeply dipping outcropping hematite body, 5 - 40 metres thick, that trends approximately north-south with a narrower fold limb extending to the northwest.
Mineralization
The resource contains massive and laminated hematite with minor intercalations of schist in the central and southern part of the ore body and softer more granular hematite in the north, particularly north of the Vila Nova River where it becomes interspersed with iron rich schist (itabirite).
Drilling
From 2005 to 2007, we carried out topographic and geological mapping, surface sampling, diamond drilling, chemical analyses of surface and drill core samples, metallurgical characterization testing and review of mineral resources and reserves.
49 diamond drill holes for a total of 4,194 metres were drilled. Of these, 31 (2,951 metres) were in the portions of the deposit where mineral resources were estimated. Drilling was by wireline method with H-size equipment. Drill core samples ranged from 4.0 to 5.5 metres in length (40 percent equal to 5.0 metres). Trench samples excavated in Bacabal South were 5.0 metres.
Core samples were cut longitudinally with a diamond rock saw. One half was stored in special treated wood core boxes and the other half used for analysis.
2011 Annual information form 55
Standard logging and sampling conventions were used: the core was photographed before being sampled, and logged in detail onto paper logging sheets. This information was entered into the project database. Core recovery was very good to excellent.
Sampling and analysis
We placed the samples in reinforced plastic bags, boxed them, and sent them to two laboratories for chemical analysis: the SGS-GEOSOL facility in Belo Horizonte, Brazil and the ALS Chemex laboratory facility in Vancouver, Canada.
The following elements were analyzed: Al2O3, BaO, CaO, Cr2O3, Fe2O3, MgO, MnO, P2O5, K2O, SiO2, Na2O, SrO and TiO2 (to a detection limit of 0.01%). Ferrous Fe and LOI were also measured. Samples also underwent material characterization analysis.
Data verification
For quality control, we monitored two sets of duplicate data: regularly submitted coarse reject duplicates, and submissions to a second laboratory. Results show good reproducibility and no bias in the assay process.
Before modeling, we verified assay, collar coordinate and down hole survey data in the Vila Nova database against source data, and did not find any significant discrepancies.
In our opinion, the Vila Nova database is accurate and precise enough to estimate resources.
Technical report
The information in this AIF is partly based on the scientific and technical data in the Vila Nova technical report: Technical Report on Vila Nova Iron Ore Project, by Roberto Costa, Roberto Costa Engenharia Ltda, and Stephen Juras, Ph.D., P.Geo. of Eldorado, qualified persons under NI 43-101.
The report is dated July 31, 2007. It’s available on SEDAR www.sedar.com.

About the property
Geological setting
The Tocantinzinho project is located in the State of Pará in Northern Brazil, in the Tapajós region. It is estimated that the Tapajós historically has produced up to 30 million ounces of gold from artisanal miners exploiting both alluvial and sapprolite hosted gold.
Exploration
Artisanal miners have been active at the Tocantinzinho project since the 1980’s but the bedrock potential of the area was not fully recognized until diamond drilling was completed by Brazauro, beginning in 2003. Brazauro continued exploration of the property until Eldorado optioned the project in 2009. Drilling of the main deposit area, conducted first by Brazauro and subsequently by Eldorado, has defined a body of disseminated mineralization measuring over 700 metres in strike length by up to 180 metres wide. The deposit has been drilled to maximum depth of 400 metres below surface to date, and remains open at depth.
Exploration outside of the main deposit area is directed towards identifying drilling targets that might yield satellite mineralized bodies. To date, this work has included airborne magnetic and radiometric surveys, IP surveys, collection of outcrop and channel samples (mainly from artisanal workings), and extensive grid-based soil sampling programs. Geochemical and geophysical anomalies identified by these means are typically followed up with detailed infill soil sampling programs, and testing with either power auger drilling, reverse circulation drilling or diamond drilling.
Geological setting
The Tocantinzinho project lies within the Tapajós gold district, in the south-central part of the Amazon Craton. The district is dominantly underlain by granitic rocks of Paleoproterozoic age.
The oldest mapped rocks are gneiss, schist, and metagranite of the Cuiu-Cuiu complex (2,011-2,033 Ma), which are intruded by granite and granodiorite of the Parauari Suite (1,957-1,997 Ma), tonalite, diorite and granodiorite of the Tropas Suite (1,898 -1,907 Ma), and granite and granodiorite of the Creporizão Suite (1,853- 1,893 Ma). Extrusive volcanic rocks of the Bom Jardim, Salustiano, and Aruri Formations (1,853
2011 Annual information form 57
1,900 Ma) cut or overlie all of these units. Alkaline granites of the Maloquinha Suite (1,870-1,882 Ma) are widespread and intrude all older rock units.
Gold mineralization is found throughout the Tapajos district. In addition to Tocantinzinho, known deposits include Cuiu-Cuiu , Palito, Ouro Roxo, São Jorge, Sucuri ,V3-Botica, Bom Jardim, Doze de Outubro, and
Mamoal.
Many of the known gold occurrences in the Tapajos, including Tocantinzinho, are along a northwest trending regional lineament known as the Tocantinzinho Trend. The trend is readily visible in regional topographic data, satellite images and airborne geophysical data. The Tocantinzinho deposit is elongate in this same northwest orientation and is interpreted to be spatially controlled, at least in part, by this regional-scale structure.
The most widespread igneous rocks in the immediate area of Tocantinzinho are the granites and quartz-monzonites of the Parauari Suite. Much of the gold mineralization encountered to date is hosted by coarse grained, pink to grey syenogranite to monzogranite, with distinctive amoeba shaped quartz grains. This is known locally as salami and smoky granite.
Mineralization
The Tocantinzinho deposit is an elongate northwest-trending body, measuring approximately 180 metres wide x 700 metres long. It is a bulk-tonnage, sheeted to stockwork quartz vein deposit, hosted in granitic rocks of the Parauari Intrusive Suite. Gold is associated with hairline to 4 cm quartz veinlets in altered granites, and in aplite and pegmatite phases of the intrusive suite.
The mineralized zone has two types of veins and veinlets: an earlier sheeted quartz-chlorite vein system with associated pyrite, and younger veins of gray quartz with pyrite, generally with chlorite and carbonate and variable but small quantities of chalcopyrite, galena, sphalerite and native gold. The overall sulfide content of the gold-bearing zone varies from one to three percent.
The mineralized granites are cut by unmineralized andesite dykes, the largest of which widens upward and caps mineralization in the northwestern portions of the deposit. Andesite exists in other parts of the deposit as a series of northwest-striking dykes that are interpreted to have fed the larger andesite body. Both mineralized granites and unmineralized andesites are cut by post-mineral rhyolite dykes.
Drilling
Drilling campaigns, all from surface, were carried out by Brazauro between 2004 and 2008, and Eldorado since 2008. A total of 49,000 meters in 175 core holes were drilled for exploration and resource infill purposes through 2010. Additional drilling for metallurgical information (1500 metres in 5 core holes) and geotechnical information (1460 meters in 6 core holes) was also conducted. In 2011, 58 additional exploration drillholes were completed, totaling 17,400 metres, at targets peripheral to the main deposit area. All diamond drilling was done with wire line core rigs using NQ and HQ size coring.
Drill holes collars were located using a total station instrument. All drill holes were drilled at inclinations ranging from 47° to 83°, along 40° to 220° azimuths. Down-hole surveys deviation (azimuth and inclination) were taken approximately every 60 meters using the Reflex EZ Shot instrument.
Geology and geotechnical data were collected from the core and it was photographed before sampling.
Core recovery in the mineralized units was very good.
The core is stored in storage facilities near the site.
Sampling and analysis
Sample intervals from 0.2 meters to 2.0 meters were selected by the geologist and marked in the core boxes. Individual samples were then cut using a diamond rock saw. One-half of the sawn core was bagged and sent for sample preparation and analysis to SGS Geosol (Brazauro) and ALS Laboratory group facilities in Brazil.
After initial crushing, the sample was split to retain approximately one kilogram for pulverization. After pulverizing, the sample was split again to create 250 to 300 g pulps. A Standard Reference Material (SRM) sample, a duplicate sample and a blank sample were inserted into the sample stream at about
58 Eldorado Gold Corporation
every tenth sample. All samples were assayed for gold by 30 g charge fire assay with an atomic absorption finish.
Data verification
Monitoring of the quality control and quality assurance samples showed all data were in control throughout the preparation and analytical processes.
The database supporting the Tocantinzinho resource model was reviewed in detail. Checks were made to original data certificates with any discrepancies corrected prior to use in resource estimation.
In our opinion, the resource database for the Tocantinzinho deposit is sufficiently free of error to be adequate for estimation of the respective mineral resources. These data are also, in our opinion, accurate and precise enough for resource estimation.
Development
In 2009, Brazauro advised Eldorado that we had met our commitment to spend $9.5 million on exploration and development under the earn-in arrangement with Brazauro. Eldorado has since acquired 100% of the securities of Brazauro.
Work has focused on engineering studies covering the process plant, mine design, tailings management facilities (TMF), and other significant infrastructure installations, including power and access options. This work has led to compilation of a pre-feasibility study and report issued in July, 2011. Results of the pre-feasibility study are summarized below.

About the property
Perama Hill is in the eastern Thrace region of northern Greece, in a rural area 25 km west-northwest of Alexandropoulos and 20 km south of Sappes.
Most workers will come from the local region. Supplies and services will come mainly from Alexandropoulos.
Topography includes rolling hills ranging from 250 to 300 metres above sea level. Sparse vegetation includes small oak trees and Mediterranean thorn and scrub bushes. A stand of black pines north of the project is part of the Black Pine Forest.
Access to the project is currently by farm tracks from Perama village, which is at the end of a 4 km long asphalt road from the main Thessaloniki/Alexandropoulos Highway. Future access will be through a new
7 km Egnatia highway service road.
Climate
The region is in a Mediterranean climate zone, with warm, dry summers and mild winters. The mean annual rainfall is 557 mm.
Operations
Conventional open pit mining will be used at Perama Hill.
The pit will operate one 8-hour shift 5 days per week. The crushing circuit will operate16 hours per day, 7 days per week. The mining and crusher loading operation will not run 24 hours per day because of its proximity to the local village. The processing plant will operate 24 hours per day.
The mine will use six 33 tonne trucks and two matching backhoes. A front-end loader will be used for the ore stockpile at the crusher.
The process plant will use water from recycled sources, a local borehole as well as surface runoff where possible.
The tailings management facility will have a structural fill embankment and filtered tailings, and be close to the open pit. It will be lined with an impermeable HDPE membrane.
Metallurgical test work, including studies of crushed composite drill core samples, has been carried out on hard and soft material, and on a composite representative of the ore. The results indicate that the material is all non-refractory and a standard carbon-in-leach circuit can be used for gold extraction.
Based on this testing, Aker Solutions E&C Ltd. (now Jacobs Engineering) designed a three-stage crushing circuit followed by a single stage ball mill, operating in closed circuit with hydro cyclones.

Environment
We are in the process of obtaining an environmental permit license.
This process is initiated by submitting a Preliminary Environmental Impact Assessment (PEIA) study to the Ministry of Environment (MOE), which acts as the lead agency in the permitting process. The MOE carries out a detailed review of the environmental impact study, coordinates input from the Ministries of Agriculture, Culture, Development, and Health, and manages a public consultation process that involves a series of public meetings. At the same time, the MOE establishes environmental terms of reference that define the environmental criteria the mine will operate under. Once these have been reviewed and finalized in an Environmental Impact Assessment (EIA) report, the MOE will approve the environmental impact study, followed by approval from the five ministries.
In October 2000, Perama Hill’s preliminary environmental impact study was submitted by Frontier Resources Limited to the MOE. Also in that year, petitions were filed against the MOE to annul the Pre-Approval Act, which established the framework for Perama Hill’s environmental impact study. On August 18, 2008 the 5th Session of the Conseil d’Etat accepted the petition for annulment and invalidated the Pre-Approval Act, which invalidated the environmental impact study.
In 2009, Eldorado submitted a new preliminary environmental impact assessment (PEIA) under the amended Pre-Approval Act. This assessment describes the environment and the Perama Hill project, and includes an evaluation and assessment of the project’s environmental impacts (landscape and visual, soil, land cover, surface water and ground water). Approval for the PEIA was received from the MOE on February 21st, 2012, this represents a major milestone in the permitting process as it marks the acceptance of the project by all ministries. The next step in the process is the submission and approval of the Environmental Impact Assessment (EIA) study. This study addresses the terms of reference issued by the ministry arising from the PEIA review. Following approval of the EIA, a series of construction and operations related permits will be applied to the project leading to start of production at the mine.
Exploration
Gold mineralization was discovered in the Perama Hill area in 1994 during follow-up prospecting of areas identified during a reconnaissance BLEG sampling program. Early exploration programs in the project area included soil and stream sediment geochemical surveys, and channel sampling over exposed stockwork zones. This work identified two centres of mineralization, corresponding to the Perama Hill deposit and the Perama South prospect.
Reverse circulation and diamond drilling were completed over both zones between 1996 and 1998, totaling 17,586 metres. An additional 1,866 metres of infill reverse circulation drilling was completed in 2000. No significant exploration work has been completed on the property since that time.
2011 Annual information form 63
Geology and mineralization
Geological setting
The property is on the eastern margin of the north-south trending Early Tertiary graben, which is covered by the Sappes alluvial plain 15 km north of the deposit.
The graben is infilled with intermediate to felsic ignimbrites and epiclastic rocks, andesitic hyaloclastites, and debris flow breccias, intercalated with fossiliferrous limestones, marls, and sandstones of Cenozoic age (25-35 Ma). The adjacent horst blocks are a combination of lower to middle greenschist facies meta-volcanic and meta-sedimentary rocks of various Mesozoic ages.
The dominant structural feature in the area, the East Graben Fault, juxtaposes the Cenozoic sequence against strongly deformed Mesozoic meta-volcanic rocks. Following east-west extension and associated graben development, the area was overprinted by a phase of transpression with sinistral movement and uplift.
The deposit is hosted by volcaniclastic sandstone that overlies andesitic volcanic breccias. The sandstone is thickly bedded to massive and contains crossbedding, wood fragments and fossils. The andesites are composed of dominantly in-situ and reworked hyaloclastite, with intercalated andesitic conglomerate beds and thinly bedded reworked ash tuff.
Mineralization
Perama Hill is a high sulphidation epithermal disseminated gold deposit, overprinted by banded quartz-chalcedony, barite, and pyrite stockwork veins and veinlets. The deposit extends 750 metres north-south, and up to 300 metres east-west. It ranges from 15 to 20 metres thick at the flanks to up to 125 metres thick at the centre. The eastern margin is marked by the East Graben Fault.
Approximately 80% of the gold mineralization at Perama Hill occurs in the sandstone unit, where gold is disseminated and associated with very fine-grained pyrite and telluride minerals. Mineralized sandstones display pervasive silicification, and contain cavities and voids filled with barite or kaolinite. The remaining 20% of the system occurs in veins that cut the underlying andesite.
The deposit has been deeply oxidized. Oxidation extends roughly to the sandstone/volcanic breccia contact, allowing a thickness of more than 100 metres of oxide mineralization in the centre of the deposit. This limit diminishes laterally to 15 to 20 metres at the deposit margins.
Drilling
There were drilling campaigns on the Perama property in 1996, 1997, 1998 and in 2000.
In total, 75 diamond drill holes were drilled, (9,093 metres), and 137 RC holes were drilled, (9,116 metres). Collars of all holes were surveyed at the end of each drilling phase. Only some of the deeper diamond holes were surveyed for downhole deviation, but since almost all the drill holes were less than 100 metres long, deviation was not expected to be a significant factor.
Sampling and analysis
The core and reverse circulation chip samples were transported to the TGM sample preparation facility located near the town of Sappes, where the core and chips were logged for geology and geotechnical information, and then photographed (core only).
The core was marked in 1 metre intervals and sample tickets were placed at the end of each interval. The core was then cut in half with a diamond rock saw. One half of this material was returned to the core box.
The reverse circulation samples were collected in 1 metre intervals and split to get a 1 kg sample. This sample was split in half again to produce a duplicate.
Samples were sent to the SGS-FILAB laboratory in France for analysis, where they were:
● | pulverized with a ring mill to 90% less than 150 mesh |
● | fire assayed for gold using a 30 g sample size |
● | sent for 32 element ICP analysis. |

Samples were controlled by a quality assurance and quality control program, which included inserting blank and Standard Reference Material (SRM) samples into the sample stream, and preparing duplicate samples for analysis in a later sample batch. At the end of each phase, pulp samples were forwarded to Australian Laboratory Services of Perth, Australia, to check gold assays. The analyses were found to display acceptable precisions but showed an approximate 5% low bias in samples from the core drilling programs.
Data verification
All the assay values supporting the Perama Hill mineral resource estimates have been concluded to be in control. The low bias observed during parts of the diamond drill campaign is believed to have minimal impact on the mineral resource estimates. In places, the gold grade estimate may be slightly understated.
The data in the database that was used to estimate the mineral resource has been verified by checking it against original assay certificates. In our opinion, the Perama Hill database is accurate and precise enough to estimate resources.

About the property
The Stratoni project is located in the Chalkidiki Peninsula, Northern Greece. The properties comprise a group of granted mining licenses, covering 317km2, approximately 100 km east of Thessaloniki, which is the second largest city in Greece and is served by its own airport. It is readily accessible by car and bus, and the road network in the area is among the best in Northern Greece. The mine lies 3.5km west-northwest of the Company-owned port and loading facility at Stratoni village, along a paved road in a river valley that rises to the west to a maximum elevation of some 600 metres above sea level. The area is centred on coordinates 474000E and 4488000N of the Hellenic Geodetic Reference System HGRS ’80, Ellipsoid GRS80, (approximately Latitude 40° 36’ and Longitude 23°50’).
The Stratoni project itself is located within mining concessions numbered F12, F15, F16, F17 and OP25 which collectively have an area of 38km2. All mineralization and mine infrastructure relevant to the Stratoni operation and discussed below lies within the boundaries of these concessions. No expenditure is required to keep the permits. No royalty is payable on future production. In addition to the concessions, the Company also owns the land containing the entire surface infrastructure associated with the mine.
The area is well served by main power supplies via the Public Power Corporation. Communications by telephone and broadband are good and Hellas Gold has a backup microwave phone and data link at Stratoni. There is sufficient water available to support the operation from creeks, re-circulated clean water from milling operations and high groundwater levels.
The mine site comprises mine offices and change house, railed access into the mine and trackless decline portal, tailings facility, mill and flotation plant, laboratory and port facility.
Climate
The Chalkidiki Peninsula climate is generally mild with limited rainfall. Over 300 days or around 3,000 hours of sunshine are recorded on average annually. Average temperatures fluctuate little during the year. The lowest temperatures occur during December to February and range between 3.5°C to 19°C, while highest temperatures occur during summer months and range between 23°C and 34°C. Temperatures below 0°C are limited to the mountainous areas. Operations continue all year round.
The area is wooded with oak, beech and pine being the principal species, while inland there are vineyards and farmlands. The main farming products are wine, honey, olives and olive oil.

Operations
Mining is a combination of transverse and longitudinal cut-and-fill with rock breaking by conventional drill and blast. This mining method is ideally suited to the high-grade orebody as it minimizes dilution and maximises recovery of high-grade ore, allowing headings to change direction with changing ore geometry. The Government’s Ministry of Industry has approved this mining method.
A main ramp has been driven in the footwall down to the 126 metres level and up to the 296 metres level. Access crosscuts to intersect the orebody are driven from the main ramp. Access to the mine is via two trackless declines and one tracked adit. The lower decline connects between the lower part of the main ramp at 140 metres and the surface at 220 metres was finished in 2008. An upper decline connects the 296 metres and the 360 metres levels at surface and was finished in 2009. Production in ore commences after the access crosscut where the ramp reaches the footwall of the orebody, usually midway along its strike length. The stope development heading is usually 4.0 metres x 4.0 metres. This may be adjusted to allow for pinching and swelling. Ore is removed from the stope after blasting using load haul dump machines. The ore is tipped into the orepass system alongside the main ramp or in the lower areas directly into the dump trucks. A loading bay is developed if logistically necessary. The stoped area is then barricaded and fill is poured via 120 millimetre and 150 mm pipes from surface at a rate of approximately 40 cubic metres per hour. Tight fill is essential for safe operation in drift and fill mining.
Previous mining has generated considerable experience with the ground conditions and the rockmass physical and geotechnical characteristics. Support to the drives is on a 1.5 metres grid pattern utilising 2.1 metres Swellex bolts with additional shotcrete or steel arch support where required. Support to the slashed area is implemented as required.
The Stratoni concentrator plant is currently operating on a campaign basis five days a week at a rate of approximately 40 t/h of ROM ore from the Mavres Petres mine. Lead, silver and zinc recoveries of 92%, 83% and 92%, respectively, are achieved. The grade of the bulk lead/silver concentrate is typically 70% Pb with 1,641 g/t Ag; the zinc concentrate contains 49% Zn. The crushing facility is capable of crushing up to 750,000 DMT per annum and as a consequence is currently only operating for one third of the available time. The ore is dry-crushed to minus 20mm size and is conveyed to a fine ore bin. Ore is then wet ground to 80% minus 212 microns in a conventional rod mill/ball mill circuit. The flotation scheme is operated in the differential mode. Lead is floated first and the zinc minerals are subsequently recovered from the lead circuit tailing. Standard reagents and pH control are used in the flotation circuit to achieve production of the two concentrates. A 13 metres diameter thickener and a 1metre diameter by 4 disc filter are used to dewater lead concentrate. Two 10 metres diameter thickeners and a 1metre diameter by 5 disc filter are used to dewater zinc concentrate. The lead and zinc concentrates are weighed and conveyed to storage sheds awaiting shipment to the smelter.
The sludge from the water treatment plant is currently disposed with the fine flotation tailings in the Chevalier settling ponds as filter cake produced from a filter press commissioned by Hellas Gold in 2008. The combined capacity of the two lined tailings ponds is sufficient for the current life of mine when using the filter presses.
The lead and zinc concentrates produced from Stratoni Operations are sold pursuant to off-take agreements entered into in July 2011 for the sale of 22,000 wet metric tonnes (wmt) of lead concentrate and 43,000 wmt of zinc concentrate from September 2011 through February 2013. In addition, Hellas Gold agreed in April 2007 to sell to Silver Wheaton (Caymans) Ltd. all of the silver metal to be produced from ore extracted during the mine-life within an area of some 7 km² around its zinc-lead-silver Mavres Petres mine, up to 15 million oz., or 20 million oz. if additional silver is processed through the Stratoni mills from areas other than the current producing mine. The Company receives 90% of payment on shipment with the balance paid on final invoice.
68 Eldorado Gold Corporation
On-going water pumping, treatment and backfilling at Stratoni are conducted in accordance with the company’s commitments under its environmental permit. Currently mine water is directed to the water treatment plant at Madem Lakkos, with additional water treatment capacity at a second water treatment plant located next to the mill at Stratoni. In the extremely unlikely event of emergency water storage being insufficient, soda ash is stocked at the mill for manual addition at the Emergency Water Storage Pond. This would bring the pH to greater than 6 and the water quality suitable for temporary discharge directly to watercourses following local consent. The strategy is to reduce rainwater entering the mine through the old sub-level caved areas. This is achieved by backfilling old mining voids compacting surface areas above and using pipes and channels to direct surface run-off water away from old mining sites.
Exploration
There is a long history of mining in the project area. Ancient mining reached a peak during the time of Phillip II and Alexander the Great. The lead-rich ores from the Madem Lakkos mine at Stratoni were smelted for silver. It has been estimated, from the volume of ancient slags that about 1Mt of ore were extracted during this period. It is believed that the Stratoni mine continued in production through the Roman, Byzantine and Turkish periods.
The Hellenic Fertiliser Company carried out extensive programs of surface and underground drilling in order to define orebody dimensions and to explore the area around them. Partial logs are available for this work but none of the original cores are available in labelled boxes, none of the holes were surveyed and no assays, certifiable or otherwise have been found. It is believed that ore was identified solely by visual assessment of the core. Where available, the partial logs of this work have been entered into the database but only in order to guide exploration work and for use in the modelling of major geological units. After 1996, TVX conducted an intense programme of drilling as detailed in the “Drilling” section below.
Underground sampling of the orebody has been carried out since 2007 and these data have been included in the current mineral resource.
There had been no historic exploration in the Stratoni area using geophysical or geochemical techniques prior to 2007.
Airborne geophysical surveys using magnetic, radiometric, and electromagnetic techniques were completed for the European Goldfields in late 2007. Interpretation indicates conductors to the west of current mineral reserves at Mavres Petres and to the northwest of the mined out Madem Lakkos deposit.
Geology and mineralization
Geological Setting
The tectonic structure of Greece consists of elongated tectono-magmatic terranes which represent successive episodes of subduction. One such terrane is the Serbo-Macedonian massif which hosts the Stratoni deposit. The Stratoni mine mineralization is classed as lead-zinc-silver carbonate replacement type mineralization, with pyrite, galena and sphalerite as the main ore minerals. The entire current mineral resources of the Stratoni mine are contained within the Mavres Petres ore body which consists of an east-west lens of Lead-Zinc - Silver mineralization and is generally strata bound within a marble horizon adjacent to the Stratoni Fault. The mined out Madem Lakkos mine mineralization lies to the east of and is similar to that at Mavres Petres and occurs in the axis of an antiform within a lower series of marbles. It is noted that there has been no significant exploration of the marbles of either the upper or lower horizons between the two known deposits which lie some 2 km apart. The massive sulphide mineralization has a relatively simple mineralogy, and the most abundant ore minerals are pyrite, sphalerite, galena, arsenopyrite and chalcopyrite.
2011 Annual information form 69
Mineralization
The Stratoni polymetallic ore consists of stratabound replacement mineralization hosted within marble horizons and may be termed a distal skarn. The mineralized zone is often referred to as the Stratoni-Piavitsa belt, and the total sulphide content of this belt prior to mining has been estimated at 25 Mt. The deposits consist of massive sulphide carbonate and aplite replacement, restricted to two marble horizons, interlaid with biotite gneiss and schist.
The massive sulphide mineralization has a relatively simple mineralogy; the most abundant ore minerals are pyrite, sphalerite, galena, arsenopyrite and chalcopyrite. The dominant exploited minerals historically have been pyrite, sphalerite and galena. The ore is also gold bearing; gold is mostly associated with the arsenian pyrite and arsenopyrite. Quartz, calcite and minor rhodochrosite form the gangue minerals.
The Mavres Petres orebody is some 500 metres in strike length, between 100 metres and 340 metres in dip extent. The true width is on average 25 metres. The strike of the orebody is close to east west and the dip is 30° to the south. The Mavres Petres orebody shows an average gold grade of around 4 g/t to 6 g/t. Its presence is strongly associated with arsenical pyrite and arsenopyrite, which appears to be a different stage of mineralization within the matrix of hydrothermal breccias or in veins cutting the lead-zinc sulphides. The gold mineralization is not coincident with the massive sulphide mineralization. The gold is completely refractory and not considered to be of any economic value.
Drilling
The drillhole data used in the mineral resource estimations of the Mavres Petres orebody was from work carried out by previous owners, TVX, and from more recent drilling carried out by Hellas Gold. Prior to 1996, 84 surface and 132 underground holes were drilled in Mavres Petres, with 19 surface and 129 underground holes drilled in Madem Lakkos. The vast majority of these holes could not be validated, and concerns regarding their true position and recorded assays resulted in their exclusion from the estimation. After 1996, 332 drill holes were drilled by TVX into the Mavres Petres orebody, all BQ or NQ size. Only the drillholes with collar surveys, and intersections within 50 metres of the collar were used in the estimation. Holes with intersections beyond 50 metres were used to assist interpretation. After 1999, downhole survey of holes by Sperry Sun camera was standard practice on all holes longer than 50 metres. Collar surveys were picked up by total station survey. All surveys in the drillhole database were corrected for magnetic declination. Hellas Gold has completed 119 drillholes and continues to survey holes greater than 50 metres length.
Core is logged on the basis of lithology, all sulphides are logged as BPG (blende, pyrite, galena), mixed ore (pyrite > blende/galena) and pyritic ore. Lithologies logged were gneiss of various types, marble and aplite. Structural as well as minor geotechnical information was also logged. The orebody at Mavres Petres is drilled on nominal 25 metres spacing and is open down dip and along strike to the west. The drill orientation with respect to ore is highly variable since most of the holes were drilled in fans from mine infrastructure close to the orebody. Angles to the strike and dip of the orebody range from perpendicular, where drill widths represent true widths, to as low as 30 degrees where drill widths can represent twice the true widths.
Sampling and analysis
Core
Ore intervals are sampled to honour lithologic contacts, using regular 1 metre sample interval where possible. A total of some 3,400 samples have been collected. Sampling typically extends 3 metres into the adjacent waste rock. Internal waste units are sampled individually provided they are greater than 0.75 metres in length. All samples are identified using permanent marker, with a numbered ticket attached to the core box at the start of each sample. Interval location, hole number and date of sampling are recorded for each sample on the ticket books. Additionally, a short description of the sample is reported. Where sampling core with poor recovery, often only one sample is defined between the core interval pickets. In sectors where there is better recovery, but still less than 100%, the real recovered core is proportionally
70 Eldorado Gold Corporation
redistributed in the total interval of the drilling run. Average core recovery in sampled areas is greater than 90%, which is sufficient in the opinion of management.
Channel Sampling
Underground channel sampling of production faces was implemented by European Goldfields as standard practice, for the purpose of grade control. These channel samples have been used in these mineral resource estimations.
Samples honour lithologic contacts and as mining is generally longitudinal, all drifts are sampled by face channels and crosscuts are sampled by sidewall channels. Horizontal samples are taken 1 metre above the floor, which corresponds to the underground geological mapping elevation. Internal waste units are sampled individually providing the interval is greater than 0.75 metre in horizontal width. Vertical samples are taken where there is any form of horizontal zonation evident in the face. For sidewall channels, sampling is regularized to 1 metres intervals, extending 2 metres out into the footwall and hanging wall waste units. Internal waste units, as with face channels are sampled individually. Every third advance is marked for sampling using chip channels of 1 metres length. Samples are taken in a channel which replicates the size of NQ drilling in order to ensure good sample supports. All sample preparation is undertaken at a sample preparation laboratory on site. All samples are subsequently assayed for Ag, Pb and Zn. Sample analysis is via aqua regia and Atomic Absorption Spectroscopy (AAS). Drill samples inside the ore envelope were also assayed for Fe. The primary laboratory used is the mine laboratory in Stratoni, whilst ALS Chemex is the secondary laboratory. The Stratoni laboratory used for primary assays was certified according to the ISO 9002 standard under the scope “Preparation and Chemical Analysis of Geological Mining, Metallurgical and Environmental Monitoring Samples, Certificate No 53987” for data up to 2003 when the operation closed. The ALS Chemex laboratories are certified under ISO 9002 under the same scope as Stratoni.
Following a specific gravity measurement program involving over 600 samples by both volumetric and geometric methods, the decision was taken to use a constant density for massive sulphide of 4.2 g/cm3. Waste has been assigned a SG value of 2.75 g/cm3.
Data verification
QC, since 1999, of assaying in the historic drill holes and underground channels has been undertaken by cross-checking 10% of pulps and 10% of the coarse rejects. QC samples were sent to the ALS Chemex laboratory in Vancouver, Canada and to the ALS Chemex laboratory at Gura Rosiei, Romania. This has showed that the channels and the drill hole samples are comparable datasets and that there is no significant bias in either. The fact that 1 metre sample intervals are used for both the drilling and the channel sampling and that the size (volume) of the channel samples is equivalent to drill core, means that the two sampling media offer equal sample support. There are no significant geological changes within the orebody that need to be considered in sampling, except for discrete waste zones which are sampled and modelled separately. As such, both the drill core samples and the channel samples are seen as representative. The variability of sample orientation due to the nature of the fanned underground drilling and the channel sampling of both side walls and faces within the operation has not proved problematic due to the massive nature of the mineralization. There are no significant dilution effects in the sampling since the contact between mineralised and non-mineralized material is abrupt, generally passing from massive sulphides to either barren marble or gneiss in the footwall of from massive sulphide to fault kaolinite in the hanging-wall.
Mineral Resources and Mineral Reserves Estimates
European Goldfields has adopted both the JORC and the CIM classification of geological mineral resources for reporting purposes which can be viewed as equivalent for these deposits.
No cut-off grade is applied due to the fact that the mineralization is massive and high grade with a sharp contact with unmineralized rock.
2011 Annual information form 71
Variable recovery and dilution values have been assigned for the purpose of updating the Stratoni mineral reserves. These are based on a combination of factors; chiefly, mining method, deposit geometry, sidewall rock conditions, and deposit thickness. These factors resulted in an overall recovery of 95% of designed stopes and an average dilution of 10%.
An economic model has been developed using the above parameters on the mineral reserves alone, with no inclusion of inferred mineral resources and shows an acceptable net present value for the project. Internal rate of return and payback are not applicable as the operation is up and running with no significant capital expenditure required, i.e., there are no negative cash flow years. Taxes are calculated at 24% for 2010 declining to 20% in 2014 and depreciation at a rate of 15%.
The mineral resources and mineral reserves are not affected materially by legal, environmental, title, taxation, socio-economic, marketing or political issues and the Stratoni mine is a fully permitted producing operation at the time of writing this report.

About the property
The Skouries project is located in the Chalkidiki peninsula, Northern Greece, 100 km east of Thessaloniki and 35 km by road from the Stratoni port. The area is centred on coordinates 474000E and 4488000N of the Hellenic Geodetic Reference System HGRS ’80, Ellipsoid GRS80 (approximately Latitude 40° 36’ and Longitude 23°50’).
The Skouries project itself is specifically located within the concessions numbered OP03, OP04, OP20, OP38, OP39, OP40, OP48 and OP57 which collectively have an area of 55.1 km2. The concessions were granted in April 2004 by the Greek state and are valid until 26 March 2026. They can be renewed twice for durations of 25 years each. No royalty is payable on future production. There are no environmental liabilities attached to the property and there are no expenditure commitments.
The area is readily accessible by road. The road network is among the best in northern Greece and a major highway extends to within 25 km of the property.
The area is well served by main power supplies via the Public Power Corporation. Communications by telephone and broadband are good and Hellas Gold has a backup microwave phone and data link at Stratoni. There is sufficient water available to support the operation from creeks, re-circulated clean water from milling operations and high groundwater levels.
Climate
The Chalkidiki Peninsula climate is generally mild with limited rainfall. Over 300 days or around 3,000 hours of sunshine are recorded on average annually. Average temperatures fluctuate little during the year. The lowest temperatures occur during December to February ranging between 3.5°C to 19°C, while highest temperatures occur during summer months ranging between 23°C and 34°C. Temperatures below 0°C are limited to the mountainous areas. Operations can continue all year round.
The area is wooded with oak, beech and pine being the principal species, while inland there are vineyards and farmlands. The main farming products are wine, honey, olives and olive oil.
Operations
Initial production will come from an open pit operation. The underground mine will consist of the orebody below the base of the open pit at 420 metres level (240 metres below surface), followed by a sublevel open stoping (SLOS) mining method commencing below the 30 metres crown pillar down to the minus 105 masl level. The deposit will be accessed from surface by a service decline (“Ramp”) and a production shaft. A number of production levels will be developed from the access ramp. Production levels will be vertically spaced from each other at 25 metres intervals. Each production level will have an auxiliary and permanent ventilation system to provide adequate amounts of fresh air for the safe and efficient execution of mining activities. To allow a smooth transfer of production from open pit to underground without a production gap, the mine accesses, ore handling, crushing and hoisting facilities and dewatering systems will be developed and equipped prior to the start of production. The open pit mine production schedule
74 Eldorado Gold Corporation
has been developed on a planned annual ore production rate of 8.0 Mtpa. An open pit mine operating of 345 days per year consisting of three, eight hour shifts operating 7 days a week is planned, resulting in a daily average ore mining rate of 23,200 tpd.
Some of the excess tailings from the underground mining operation will be mixed with cement and disposed of in the open pit as engineered backfill. This means that mining of the open pit has to be complete before the option of diverting the disposal of tailings away from the Tailings Management Facility (TMF) valley site and in to the open pit can be used.
Underground production commences in Year 7 with pre-production of the underground mine commencing in Year 4. Production averages 4.4 Mtpa over most of the underground mine life. The mine design is based on three operational levels that will be mined simultaneously, accessed by a main ramp, positioned close to the orebody. The base level for each mining horizon will be linked to an exhaust vent raise, creating a main return airway. Intermediate ventilation raises will link each level with the closest main return airway drift. A main intake ventilation raise, close to the main ramp will be one of the three main air intakes (shaft, main ramp and intake ventilation raise).
The process plant and infrastructure design of the project has been based on extensive testwork carried out on samples that were representative of the resource. Technical information was provided by several specialist consultants, world class metallurgical testing facilities and international engineering groups. Outotec of Finland (Outotec), have completed an Engineering Study for the project which included the supply of equipment within their manufacturing range, grinding mills, the flotation equipment, the paste thickeners and the plant control system. In parallel with this, the Athens based engineering contractor, ENOIA, completed a Basic Engineering Study and have started detailed engineering including aspects of the plant and infrastructure outside of Outotec’s scope. ENOIA will provide contract services and controls for all estimate areas of the project working under the direction of Hellas Gold.
The layout of the plant has been optimized over time incorporating many improvements which have resulted in capital cost reductions. Confirmatory geotechnical assessment is scheduled. The process plant is of conventional design comprising surface ore reception facilities and primary crusher, coarse ore stockpile, SAG and ball mill grinding, gold gravity circuit, rougher, cleaning and scavenger flotation stages, filtration and paste thickening of the tailings for disposal. In addition, the infrastructure facilities include the administration block, the workshops, fuel station and welfare facilities as well as power, water and other services. The design will take into account the ore delivery system from the underground phase of mining.

The EIS for the Skouries Mine is covered under the Kassandra Mines Mineral Deposits Project which involves an area of 26,400 ha, in north-eastern Chalkidiki (Macedonia Region). The Kassandra Mines Mineral Deposit Project will be implemented by Hellas Gold, which obtained the mining rights by a contract included in the National Law No. 3220/2004.
2011 Annual information form 75
The proposed Kassandra Mines Mineral Deposit Project includes the following sub-projects pertaining to Skouries:
• Mining Facilities of Skouries, new beneficiation plant and tailing management facility (TMF).
• Port facilities in Stratoni.
‘’ENVECO S.A., Environmental Protection, Management and Economy S.A.’’, under Hellas Gold’s management, has authored the full EIS. The full EIS was prepared principally by the application of:
● | Law 1650/86 - ’The Protection of the Environment from Projects and Activities’, as amended by Law 3010/2002. This incorporates the EU directive on Environmental Impact Assessment (85/337/EEC as amended). |
● | Law JMD107017/06 which is the Greek implementation of the SEA Directive 2001/42/EC. |
The EIS was submitted in July 2010 and was approved in July 2011. The EIS covers all environmental issues for the Project.
Exploration and Development
The European Goldfields has not undertaken any exploration drilling at Skouries. The historical owners, TVX, undertook 72,232 metres of drilling in three phases during 1996, 1997 and 1998. In 1998, TVX also commenced an exploration adit which was suspended during January 1999 after 689 m of development had been completed. The adit was flooded in October 2000.
Geology and mineralization
Geological setting
The Skouries deposit is located within the Serbo-Macedonian massif, which comprises strongly tectonised and metamorphosed Palaeozoic rocks. The massif is locally subdivided into two northwest-trending lithostratigraphic-tectonic units, namely the Vertiskos Formation to the west, which includes amphibolite gneiss flanking biotite schists and interbedded amphibolites, and to the east the underlying Kerdilla Formation, consisting of granitised and migmatised mica gneiss with amphibolite and marble horizons. The units have been intruded by Oligocene sub-alkaline porphyry stocks including the body that hosts the Skouries copper-gold deposit, and are separated by the arcuate Stratoni fault. Foliated leucocratic migmatites, locally termed pegmatites, occur within the Kerdilla Formation.
The Skouries deposit is a typical sub-alkaline copper-porphyry deposit, forming a near-vertical pipe intruded into amphibolite and biotite schist country rock. The alteration zones at Skouries are restricted in extent in contrast to well-developed concentric zones typical of high-level porphyries. The deposit occurs within an elliptical pipe of coarse-grained porphyritic syenite, part of a suite of Oligocene porphyry stocks that intrude the Kerdilla and Vertiskos Formations along a northwest trending belt.
Mineralization
Mineralization is disseminated in nature and typical of a porphyry and it is subvertical in orientation. Mineralization within the potassic zone primarily comprises chalcopyrite veinlets with subordinate bornite (0.1 mm to 5 mm thick) and disseminated chalcopyrite and bornite. Variable amounts of digenite, chalcocite, covellite, molybdenite and pyrite occur together with rare galena and sphalerite. Magnetite occurs both as disseminations and in quartz veinlets. The propylitic zone contains less than 1% disseminated pyrite and rare chalcocite.
Gold mineralization occurs as native gold associated with gangue minerals and ranges in size from a few microns to 160 microns. It also occurs as blebs within sulphides, particularly in bornite and chalcocite. Gold correlates strongly with copper.
An oxide zone occurs from surface to 30 metres to 50 metres depth and includes malachite, cuprite, secondary chalcocite and minor azurite, covellite, digenite and native copper. The main porphyry deposit comprises two high-grade areas, one near surface and a second below 350 metres depth.

Drilling
A total of 72,233 metres of core drilled during the 1996 to 1998 TVX drilling campaign were available for mineral resource estimation. During this period, TVX drilled a total of 111 long surface diamond drillholes using NQ size (47.6 mm core diameter). Holes reached to 800 metres depths. Hole deviation was measured by Sperry Sun every 50 metres depth. Drill runs were 3 metres. Collar co-ordinates were surveyed using total station DMT-410 in the pit area.
Sample Preparation, Analysis and Security of Samples
Sampling and analysis
The mineral resource estimate was carried out using only the TVX diamond drillholes. The drilling grid pattern used was 50 metres by 50 metres. Holes were drilled at an angle of some 60° to the pipe but given the disseminated nature of the porphyry type mineralization, it would be misleading to convert intercepts to true widths on this basis.
After geological and geotechnical logging, diamond drillholes were split lengthwise using a diamond saw. One half was stored for future reference and the other half was sampled at regular 2 m intervals and sent for sample preparation and assaying. Each sample was given an individual sample number and the rock type was coded.
Drillholes SK-08 to SK-30 (15,501 metres) and SOP-1 to SOP-33 (14,932 metres) were prepared at three different laboratories: I.G.M.F at Xanthi, I.G.M.F at Athens and TVX at Stratoni, the latter by TVX personnel. Drillholes SOP-34 to SOP-39 (3,045 metres) were prepared at the Stratoni laboratory by TVX personnel. Drillholes SOP-40 and onwards were prepared at the Skouries sample preparation laboratory located at Madem Lakkos by TVX personnel. Screw top plastic bottles rather than envelopes or plastic bags were used for storing and shipping the samples.
In all cases, gold, total copper, soluble copper with citric and sulphuric acid, and silver assays were done by the ALS-Geolab laboratory in Santiago, Chile that was chosen as the main laboratory. It should be noted that soluble copper assays were generally done for samples within the first 100 metres from the surface. Copper was determined by an aqua regia digest and AAS. Gold was normally assayed on a 50 g sample utilising fire assay with an AAS finish. However, as coarse gold is known to occur in the deposit, a study was conducted utilising screen fire assay using a minus 170 mesh screen and assaying the –170 mesh fraction combined with the results from the retained fraction.
Data verification
QC and quality assurance of sampling are discussed in the Skouries Technical Report (see below); it was concluded that there is no significant sample bias. Sampling was carried out on 2 metres intervals and across geological boundaries which is viewed by the Company as representative given the disseminated nature of the mineralization. Drillhole spacing is on a nominal 50 metres grid which is, in the Company’s opinion, more than sufficient sample support for the disseminated nature of the deposit mineralization.
The QC system used specified duplicate assays by a different laboratory and “blind” coarse reject checks. A size analysis of coarse rejects was done periodically to ensure that the first sample split is done when samples are below 2 mm, which ensures that the total sample preparation error is maintained within acceptable industry standards. Check assays for a large number of samples from Skouries drillholes SK-8 and SK-10 were done at the SGS laboratory in Carcassonne, France.
Mineral Resources and Mineral Reserves Estimates
Scott Wilson has reviewed and revised the Mineral Resource model and defined Mineral Reserve estimates to report the current open pit and underground Mineral Resource and Mineral Reserve estimates. The Mineral Resource NSR model is based on higher Mineral Resource related metal price assumptions. The Mineral Resource and Mineral Reserve estimates conform to the Canadian Institute of Mining’s (CIM) ‘Definitions Standards for Mineral Resources and Mineral Reserves,’ as prepared by the CIM Committee on Mineral Resources and Mineral Reserves on November 27, 2010. In Scott Wilson’s opinion, the Mineral Resource and Mineral Reserves classification results for the Skouries deposit are also in accordance with the Australasian Code (“JORC, 2004”).
2011 Annual information form 77
CIM definitions were followed for Mineral Resources. Mineral Resources were estimated using an Au price of US$1,200 per ounce and a Cu price of US$3.50/lb. Mineral Resources were estimated using a NSR discard cut-off value of €4.29/t for the open pit and a breakeven NSR cut-off value of €19.43/t for the underground.
Measured and Indicated Mineral Resources contained within the Skouries deposit that have been converted into Proven and Probable Mineral Reserves are estimated as of January 2011, in accordance with the CIM definitions. The Mineral Reserves have been used for the SLOS life of mine plan and economic analysis. Mineral Reserves have been estimated assuming an open pit mining method and SLOS method with backfill for the underground operation. The Mineral Resources are inclusive of the Mineral Reserves.
Mineral Reserves were estimated using an Au price of US$1,000 per ounce and a Cu price of US$2.50/ lb. Mineral Reserves were estimated for the open pit using a NSR cut-off value of €4.29/t and the underground using a NSR cut-off value of €19.43/t. Open Pit dilution averages 0% and extraction is estimated to be 100%. Underground dilution averages 3.5% and extraction is estimated at 95%

About the property
The Olympias property is located in the Chalkidiki peninsula, Northern Greece. The project is within a group of granted mining and exploration concessions covering 317 km2, approximately 100 km east of Thessaloniki. The area is centred on coordinates 474000E and 4488000N of the Hellenic Geodetic Reference System HGRS ’80, Ellipsoid GRS80 (approximately Latitude 40° 36’ and Longitude 23°50’). It is readily accessible by road; the road network in the area is among the best in Northern Greece and a major highway has been constructed extending east from Thessaloniki to 15 km north of the property.
80 Eldorado Gold Corporation
The Olympias Project lies 9 km north‐northwest of the company-owned Stratoni port and loading facility, along a paved road along the coast.
The area is wooded with oak, beech and pine being the principal species, while inland there are vineyards and farmlands. The main farming products are wine, honey, olives and olive oil.
Climate
The Chalkidiki Peninsula climate is generally mild with limited rainfall. Over 300 days or around 3,000 hours of sunshine are recorded on average annually. Average temperatures fluctuate little during the year. The lowest temperatures occur during December to February ranging between 3.5°C to 19°C, while highest temperatures occur during summer months and range between 23°C and 34°C. Temperatures below 0°C are limited to the mountainous areas. Operations can continue all year round.
Operations
The Olympias project is a gold‐lead‐zinc‐silver mine on care and maintenance in Northern Greece. The Company has a phased approach to developing the Olympias project:
● | the existing Olympias process plant will be refurbished to process the existing tailings; |
● | the reprocessing of existing tailings whilst refurbishing and developing the existing underground infrastructure; |
● | the processing at Olympias of ore from underground producing gold, lead and zinc concentrates; |
● | a production ramp‐up on completion of the underground connection to a new surface concentrator plant at a brown field site in the nearby Stratoni Valley allowing early rehabilitation of historic stockpiles and infrastructure in the Olympias Valley. |
As part of the phased approach, the rehabilitation of the existing concentrator plant to treat the existing tailings at up to 720,000 tonnes per annum (tpa) has commenced. The underground works are to be refurbished and developed and ROM ore will be processed at the Olympias concentrator once the tailings reserve is depleted. Ore production will reach 400 ktpa producing three concentrates for gold, lead‐silver and zinc respectively. Production will be increased to 700 ktpa to 850 ktpa in year 9 on completion of an 8.5 km decline linking the underground works at Olympias to a new concentrator to be built in the Stratoni valley (the Stratoni Decline). The process at both concentrators is broadly the same with efficiencies of process and most particularly scale incorporated at the newer site. The crushed ore will be transferred to the fine ore bin ahead of the SAG mill and the secondary ball mill. The overflow from the hydro‐cyclones
2011 Annual information form 81
classifier will be directed to the flotation circuit. The flotation section will produce three concentrates, firstly lead/silver; secondly zinc, and thirdly the gold bearing pyrite / arsenopyrite concentrate. Separation of the minerals into the three concentrates is achieved through a combination of pH control and conventional reagents for the depression and activation of the various mineral species. There is no long‐term surface disposal requirement for the coarse tailings as, by removing approximately 20% of the material as fines, the remaining coarse tailings balance the underground backfill requirement. The fine tailings will be filtered and transported as filter cake to the Stratoni Tailings Management Facility (TMF). The facilities at Olympias include a water treatment plant. There is minimal risk associated with the concentrator process as the Olympias plant has operated successfully for many years in the past, producing concentrates within the set metallurgical parameters. The recovery of the lead, silver, zinc and gold to their respective concentrates will be in the range of 90% based on previous operating history at Olympias. It is anticipated that with modern equipment and automated process control, the historical recoveries could be exceeded. Previous mining at Olympias was in the West Orebody. The proposed mining will complete the mining of mineral reserves remaining in these areas, but mainly mining the fully explored down dip extension to the West Orebody and the unexploited East Orebody. There are 13.6 million tonnes (Mt) of proven and probable underground mineral reserves remaining in the Olympias mine which will support a maximum mining rate of approximately 850 ktpa in the later phase. The chosen mining method is drift and fill based on the geotechnical conditions, environmental requirements and it was the method previously used in the mine and is currently used at the Company’s nearby Stratoni operation. It is seen as a low risk method, given the company’s experience in using it, and ensures there is no subsidence due to the use of cemented backfill.
Environment
The EIS was submitted by Hellas Gold in July 2010 and was approved in July 2011. The EIS covers all environmental issues for the project.
Accumulating impact is anticipated only in the Madem Lakkos (Stratoni) brownfield area where the new Olympias concentrator and tailings disposal facility will be constructed. The remainder of the infrastructure components are distant from each other and therefore there will not be any significant accumulating impact on the morphology of the area under study. Impact is of low significance, of local character and much will be non‐permanent and partially reversible. All measures to minimize the anticipated impact will be taken. The Olympias project will benefit the Olympias area by allowing the rehabilitation of the Olympias Valley after approximately eight years of operation.
No significant impact is expected either quantitatively or in quality on the water in the immediate mining and processing areas or those areas within the immediate regional water system. The Olympias project has been designed such that any leakage can be managed and controlled. The overall impacts are assessed as moderately positive due to the rehabilitation of the old tailings ponds and permanent restoration of the valley site when the main processing operations move to Stratoni once full ramp up to 850 kt is achieved.
Exploration
The Hellenic Fertilizer Company carried out extensive programs of surface and underground drilling in order to define orebody dimensions and to explore the area around them. Partial logs are available for this work but none of the original cores are available in labelled boxes, none of the holes were surveyed and no assays, certifiable or otherwise have been found. It is believed that ore was identified solely by visual assessment of the core. Where available, the partial logs of this work have been entered in to the database but only in order to guide exploration work and for use in the modelling of major geological units. After 1996, TVX conducted an intense program of drilling as detailed in the “Drilling” section below.
82 Eldorado Gold Corporation
By February 1999, TVX had completed a drill program comprising 760 holes totalling 91,319 metres. A mineral resource estimation was completed in June 1998 and used in a feasibility study completed by Kvaerner. The project was acquired by European Goldfields (through Hellas Gold) in 2004. No further exploration has been carried out; however checks of original assay certificates against database entries confirm the integrity of the data. Key areas of the orebody have had the interpolation checked and the overall geostatistical parameters have been checked. The mineral resource has also been audited by Behre Dolbear and SRK.
The Olympias orebody is essentially closed at near surface. It is open down plunge at depth and drilling will be considered from underground once development reaches the lower levels of the currently defined orebody.
Geology and mineralization
Geological setting
The tectonic structure of Greece consists of elongated tecto-magmatic belts of variable metamorphic grade which trend northwest to southeast. These broadly coincide with the trend of the main mountain ranges of the country. These zones represent successive episodes of subduction, resulting from the northeast movement of the African Plate during the Tertiary period. The rocks that comprise these orogenic zones consist of gneiss, schist and acid igneous intrusives. These rocks host the mineral deposits of the Kassandra Mining District.
Three main geotectonic units, following the same trend dominate north-eastern Greece; the Rhodope massif to the east, the Serbo-Macedonian massif and the Vardar Zone to the west.
The Serbo-Macedonian massif is sub-divided into two litho-stratigraphic tectonic units, the upper Vertiskos Formation to the south and west, with the Kerdilia Formation to the north and east, which hosts Olympias itself. A faulted contact named the Stratoni Fault separates the two formations.
The Vertiskos Formation is composed mainly of micaschist with intercalation of quartz lenses. It lacks the pegmatite that characterises the Kerdilia Formation. A large less deformed amphibolite is located at the contact between the units.
The Kerdilia Formation is sub-divided into two units; the Upper and Lower. The Lower Unit mostly consists of amphibolite gneiss, with lenses of foliated migmatitic rocks, named as pegmatites (and aplite). The Upper Unit consists mostly of biotite gneiss and schist interlayered with marble horizons, irregular pegmatite lenses and aplite. The marble horizons of the Upper Kerdilia Formation host the ore zones at Olympias. Both the Kerdilia and the Vertiskos rocks were affected by early ductile and later brittle deformation during the mid-Cretaceous to mid-Tertiary. During the early Oligocene the district was subjected to extensional tectonics allowing for the intrusion of a post tectonic/metamorphic suite of plugs and dikes. These intrude both the Vertiskos and the Kerdilia formations and are in the range of syenite/trachyte to dacite. Examples of these post tectonic intrusions include those at the Skouries deposit and Fisoka prospect, both of which host gold-copper porphyry mineralization.
The Kerdilia Formation is separated from the Vertiskos Formation by the Stratoni Fault, an east-west to northwest-southwest striking, southerly dipping structure which is still active and which lies to the south of the Olympias deposit. Recent movement along the fault is normal though it is thought that this was originally a reverse movement fault that placed the Vertiskos on top of the Kerdilia. The Kerdilia Formation comprises a series of biotite, biotite hornblende and leucocratic gneisses, amphibolites and marbles. A greywacke parent is suggested for some of the biotite gneisses and an igneous origin for the remaining biotite, biotite hornblende and leucocratic gneisses and for the amphibolites. Retrograde mineral assemblages in these gneisses and schist indicate a post metamorphic thermal event.
Mineralization
The Olympias mineralization is a massive stratabound polymetallic replacement deposit hosted in the marble-gneiss contact of the Kerdilia Formation. The deposit comprises pyrite, arsenopyrite, sphalerite, galena, tetrahedrite-tenantite, boulangerite and chalcopyrite with secondary cerussite, chalcocite and
2011 Annual information form 83
covellie. Manganese oxides represent alteration of rhodochrosite. Gangue minerals include quartz, calcite, rhodochrosite, feldspar, kaolinite, chlorite, ankerite and graphite. The ore minerals are mainly massive in form. Kaolinisation is the main type of alteration associated with the deposit. Hydrothermal brecciation is common and chloritisation and silicification of host rocks immediately around the mineralised section is frequently observed.
The mineralization occurs within two orebodies. The West Orebody is approximately 250 metres wide and plunges 1500 metres to the southwest. It has been intersected from surface to a depth of 500 metres and is open down plunge. Its width varies between 5m to 15m with dips averaging 30° to 35° east. The East Orebody lies some 150 metres east of the West Orebody has an anticlinal structure, exhibiting axial thickening, with steeper dips toward the peripheries. It dips an average 25° to 30° to the southeast. Its width averages 75 metres and its average thickness is 7 metres. The mineralization has been traced for 600m down plunge.
The Olympias deposit consists of massive sulphide carbonate (marble) and aplite replacement lenses interlaid with biotite gneiss and schist. The rocks of the Upper Kerdilia Formation have been folded and over thrust which has thickened and fractured the marble units. The whole of the formation was then subject to uplift with subsequent gravity collapse of the uplifted block along a series of north-northwest to north-south trending arcuate, listric faults dipping to the east. The majority of the orebody exhibits a north-south strike, with plunge to the south-east. A common feature in the district is the presence of irregular lenses and vein type intrusions of aplite which postdates both the ore and host rocks.
Drilling
Only those holes drilled by TVX since 1996 were utilised for mineral resource estimation purposes as there is no means of validating those drilled by earlier operators. TVX drilled some 760 holes totalling 91,319 metres. Excluding samples with less than 60% recovery, which were eliminated from the mineral resource estimation, the overall recovery averaged 88.6%.
Core was logged on the basis of lithology. All sulphides were logged as blende (sphalerite), pyrite, galena (BPG), mixed ore (where pyrite is dominant) and pyrite/arsenopyrite ore. Lithologies logged were gneiss of various types, marble and aplite. Structural as well as minor geotechnical information was also logged. The orebody at Olympias was drilled on a nominal 25 metres to 45 metres spacing and the orebody is open down dip and along strike to the west. The drill orientation with respect to ore was variable since most of the holes were drilled in fans from mine infrastructure close to the orebody. Angles to the strike and dip of the orebody range from perpendicular, where drill widths represent true widths, to as low as 30° where drill widths can represent twice the true widths. For this reason particular attention was paid to compositing of the 1 metres samples during the mineral resource estimation process. All drilling in the current mineral resource was conducted by TVX but the logs to these drillholes and the sample QC have been validated.
Sampling and analysis
After the core was brought from the underground or the surface drilling rig, geological and geotechnical logging was completed. During this stage, samples were defined by marking ‘from’ and ‘to’ points on the core. A detailed lithological and mineralogical description is given for each sample, which was then summarised in a two digit numeric code.
The sampling interval through the ore zone was 1 metre, except when lithological changes occurred. The sampling interval was adjusted so that different rock types were sampled separately. In general, 5 metres to 10 metres of waste into the hanging wall and footwall was sampled using 2 metres regular intervals and analysis of fully sampled cores has shown that this was sufficient to verify any low grade mineralization in the country rocks around the main zones. This sampling policy led to some 13,500 samples being taken over the 1,500 metres strike of the orebody. No factors were found to have affected the accuracy of the sampling and they have been found to be representative.
84 Eldorado Gold Corporation
After geological mapping and geotechnical logging, samples were defined as described above and the core was split longitudinally by diamond saw. Samples were then placed in labelled plastic bags and sent to the Stratoni laboratory for sample preparation. The remaining half core was stored in a core shed until 2002 and was then containerised and these containers are kept locked on site.
All samples were routinely assayed for gold, silver, lead, zinc and arsenic. Initially, SGS Laboratories in Carcassonne, France were used for gold assays, while the remaining elements were determined at the TVX-Stratoni laboratory in Greece. The Stratoni laboratory used for primary assays was certified according to the ISO 9002 standard under the scope “Preparation and Chemical Analysis of Geological Mining, Metallurgical and Environmental Monitoring Samples, Certificate No 53987” for data up to 2003 which includes all data relating to Olympias. This procedure was followed for the first 2,000 in-fill samples. Approximately 12% of these were sent to the Chemex Laboratories in Canada to be assayed for all five elements as part of the QC procedure. Both assay houses used fire assay with AAS finish on 50gm samples for gold determination. AAS was used for the base metals. Gold showed satisfactory results but silver and lead determined at Stratoni showed high negative bias compared to Chemex, while zinc and arsenic results showed no bias. It was decided to keep the SGS laboratory gold assays for the first 2,000 samples but to re-assay all ore samples for Ag, Pb, Zn and As at Chemex and use Chemex for the remainder of the project.
Data verification
Subsequently, 9% of pulps were submitted on a routine basis to ALS-Geolab in Chile for check assaying. Statistical analysis of check assays for zinc and arsenic were within acceptable standards. Gold assays varied by 2% with Chemex again the more conservative. Some 4% of the coarse rejects were submitted under a different name to the Stratoni sample preparation facility and, following homogenisation, were split using a Jones splitter and a 400gm sample pulverised and split into two. The results from the coarse reject re-assays indicated that the Stratoni preparation facility was operated in accordance with high procedural standards.
Mineral Resources and Mineral Reserves Estimates
No cut-off grade is applied within mineralization lenses due to the fact that the mineralization is massive and high grade with a sharp contact with unmineralized rock. Although certain lenses of mineralization were excluded by TVX as the prevailing metal prices could not justify the cost of development to mine them.
The mineral resources tonnage and grade has been calculated using geostatistical methods within Gemcom mining software. The main steps of the geological estimation process were: construct lithology geological solid models; composite drillhole samples into 1 metre intervals; conduct basic statistics on both the raw and composite assay data sets; conduct geostatistical analysis for each element for each lithology; generate unconstrained three dimensional mineral resource block models; validate the mineral resource block model with primary data.
Previous mining at Olympias was in the West Orebody above the minus 220 metres level. The proposed future mining plan includes completing the mining of mineral reserves remaining in these areas, but mainly mining the fully explored but unexploited East Orebody and the down dip extension to the West Orebody. The geotechnical conditions influence strongly the choice and layout of mining methods.
Based on the current estimates of mineral resources and mineral reserves of the Olympias deposit, the Company believes that there are sufficient mineral reserves currently defined to sustain an approximate 25 year mine life.

In December 2008, the European Commission initiated an investigation into alleged state aid by Greece in favour of Hellas Gold based on an anonymous complaint by an individual. The complaint alleged that in 2003 Hellas Gold received state aid from Greece in respect of non-payment of real estate transfer taxes and legal fees and in respect of the price paid for the former assets of TVX (see “Stratoni Project – History” for details regarding previous ownership of the Hellas Gold assets).
The investigation was in respect of the Greek state’s compliance with its treaty obligations regarding EU competition policy. Hellas Gold itself was not under investigation and its title to the assets it acquired was not under question and is not jeopardised by any ruling respecting this investigation. The underlying premise was that state aid can be (but is not always) incompatible with the Common Market.
A decision of the European Commission of 23 February 2011 concluded that the sale of the mining licenses in 2003 by the Greek state to Hellas Gold was carried out below its real market value and, therefore, involved indirect subsidies in breach of EU state aid rules. The subsidy was calculated by the European Commission at €14 million. The European Commission also asserts that Hellas Gold did not pay transaction taxes amounting to €1.34 million; and on that basis alleges that the total amount to be recovered from Hellas Gold to the Greek state is €15.3 million, plus interest.
Based on the legal, economic and factual elements relied upon by the European Commission in making its finding of state aid in favour of Hellas Gold, the Greek state, European Goldfields Limited and Hellas Gold have each sought to contest the decision on the basis that it is flawed and does not accurately reflect the entire circumstances and issues surrounding the December 2003 acquisition. Proceedings in the European Court have been started and the hearings are expected to commence at the end of 2012.
Arbitration Proceedings
In September 2007, Hellas Gold entered into a contract for the sale of gold pyrites ore to Eureka Mining plc (“Eureka”). Eureka lifted significantly less than the agreed quantity of ore in the timescale specified in the contract, which was subsequently amended. In April 2011, London solicitors acting for Eureka asserted a claim for market loss of $4.34 million plus a claim for “loss of profits” of $15.28 million. The letter also sought repayment of $567,400 charged by Hellas Gold to Eureka for an agreed contractual extension of the lifting period.
Eureka referred the dispute to arbitration under the rules of the International Chamber of Commerce (“ICC”). The ICC Tribunal was constituted in December 2011 and the full hearing will take place in November 2012. The alleged loss of profits claim is now being put forward by Eureka as between $6.8 million and $11.1 million. Hellas Gold SA has served a clear defence denying liability and contending that not only is Hellas Gold SA not in breach but that it is Eureka who were and are in breach of contract, having failed to lift the required contractual quantity.

Licenses, permits and royalties
Mining | Certej exploitation concession: covers 26.7 km2; granted for a period of 20 years, with an initial development-exploitation period of 5 years commencing on the day the concession was gazetted on the 25 January 2000. The Company currently holds, through Deva Gold, an exploration concession for the Baita-Craciunesti area (which is in the process of being converted to an exploitation concession). The Company has recently acquired two prospecting licenses – the Brad and the Deva-Muncel concessions – that collectively cover 475km2 to the northwest and southwest of Certej. The Company is in the process of acquiring the land, through purchase and/or lease, which will contain the surface infrastructure associated with the mine. |
Permits | In March 2007, the Company submitted a TFS to the Romanian government in support of a permit application to develop the project. The TFS was approved in July 2008 and a permit to mine the deposit subsequently granted. As of May 2010, the approval process for the full Zonal Urbanization Plan permit for Certej was concluded with final sign off by the local authorities. An EIS was compiled and submitted to the Romanian authorities in August 2010. On March 9, 2011, with the initiation of the final public consultation process, the Company reached the final stage of the environmental permitting process to obtain the permits for construction and operation of the Certej project. |
About the property
The Certej project is located in the southern part of the Apuseni Mountains in central Romania, some 12km NNE of the regional town of Deva in Hunedoara County. The nearby town of Deva is served by a national road and a railway line from Bucharest. A major river, the Mures, runs within 10 km of the proposed site and 110kVA power lines and water come to within 2 km of the site. Asphalted roads run directly to the deposit. The closest international airport is at Sibiu approx. 109 km towards Bucharest from Deva on the national road E68. International airports are also located at Cluj (180 km) and Timisoara (168 km). A regional airport is also planned for construction near Deva at the existing small airstrip as part of EU accession.
Climate
The climate is mild temperate-continental, with mean temperatures of around 23°C in summer and -3°C in winter. Exploration and mining activities can continue throughout the year. Elevations within the project areas range from 400 metres to over 1,100 metres above sea level but with the hills around the deposit itself reaching a maximum of around 600 metres. Much of the area is hilly with incised valleys. The hills are forested with beech and oak with occasional conifers, particularly at higher elevations. Scattered small rural settlements, associated pasture, and other agricultural land occur at lower elevations, on gentler slopes and in the river valleys. The proposed site for the Certej project itself comprises an area previously used for open pit mining with associated dumps, secondary and tertiary forest and rough pasture. The hills continue to the north, east and west of Certej. The Certej valley drains the project area and the terrain grades into the Mures River alluvial floodplain to the south of the project area.
2011 Annual information form 89
Operations
The deposit extends from surface and will be mined by open pit methods with a strip ratio of 3.1:1. The project will involve the mining and processing of 3.0 million tonnes of ore per annum.
The engineered pit designs were based on Whittle optimization to determine the general pit shape and depth. This comprised a main pit over the east, intermediate and central zones of the orebody and an adjacent smaller pit over the west zone. The final pit depth is approximately 220 metres in the East pit, and approximately 200 metres in the West pit. Optimised pit shells generated by Whittle were used as guidance to detail engineer the pits, including exact ramp positions and bench configuration. Average overall pit slopes including ramps are generally 40° to 60° according to geotechnical conditions but flatten to 30° in some places at the pit rim.
The metallurgical process involves the production of a gold and silver-bearing concentrate utilizing conventional mineral processing technology followed by the production of gold and silver bullion in doré on site by means of the Albion process. The Albion process is a combination of ultra-fine grinding of the concentrate with oxidative leaching at atmospheric pressure. The liberated gold and silver is then recovered as doré by the conventional CIL process.
The process plant will comprise a conventional 9,500 tpd concentrator with crushing, grinding and sulphide flotation unit operations. The refractory gold and silver bearing sulphide flotation concentrate will then be directed to the Albion process plant where the (pyrite sulphide) concentrate will be oxidised and the solid residue will be directed to the CIL and precious metals plant to recover the liberated gold and silver as a doré. The process does not employ autoclaves or rely on bacterial cultures. The residues from the flotation and gold plants will be disposed of in two separate but adjoining, Tailings Management Facilities (TMF).
The project is scheduled to produce an average of 308,000 tonnes of flotation concentrate per annum with high grades between 17 – 19 g/t gold and 80 – 130 g/t silver, depending on the source of the ore in the deposit, with flotation gold and silver recoveries of approximately 90%. The Albion process gold and silver recoveries will be approximately 90% and 85% respectively, resulting in total process gold and silver recoveries in the region of 81% and 77%. The silver recoveries for the west ore type will be slightly lower than the other three zones. This will yield approximately 160,000 oz of gold and 820,000 oz. of silver per year in doré.
Detailed technical and economic studies on Certej culminated with the acceptance of the technical feasibility study (TFS) for the Certej project by the National Agency for Mineral Resources (NAMR) in July 2008. The TFS was further updated to incorporate an optimisation of the tailings facility sites and additional mineral reserves defined from in-pit lower-grade material and existing dumps, announced in January 2009.
Environment
An environmental impact statement was produced in 2007 in accordance with the provisions of the Order of the Ministry of Environment and Water Administration No. 863/2002. This EIS report was produced by a consortium of Romanian agencies and institutes who prepared separate reports for the individual sections of the EIS. Their main findings are;
● | Water: ICIM of Bucharest concluded that by treating the acid rock drainage from the dumps the quality of water in the Hondol and Certej streams would meet all standards required and would improve the Mures River water quality. Water discharged from the TMFs to the local river system would be treated and comply with the admissible values laid down in NPTA 001/2005 and 002/2005. |
● | Wastes: ECOIND of Bucharest defined and categorized all the wastes that would be produced during the three phases of the project: construction, operations and closure. |
90 Eldorado Gold Corporation
● | Air: AMEC (formerly AGRARO) assessed all airborne pollution and dispersion patterns during the project life using various BAT computer models. They stated that the specific management actions would keep the air quality well within admissible levels. |
● | Biodiversity: AMEC found that there were no material risks to flora, fauna and animal life. |
● | Social Impact: Studies on the ‘Social and Economic Environment’ and ‘Ethnic and Cultural Environment’ were produced. They concluded that the project would impact positively on the communities because of population stabilisation and the economic benefits. |
● | Archaeology: 52 archaeological trenches were excavated by the Deva Museum and no prehistorical vestiges have been found in the mine site area. |
● | Risks and Hazards: An analysis by OCON Ecorisc SRL concluded that the use of cyanide, explosives and the TMFs posed the greatest risks but this was very low due to the mitigating measures to be installed. |
An EIS was compiled and submitted to the Romanian authorities in August 2010. On 9 March 2011, with the initiation of the final public consultation process, the Company reached the final stage of the environmental permitting required for the construction and operation of the Certej project.
Exploration
From the 1970s, exploration at Certej continued under the control of the Romanian state companies S.C. Minexfor S.A. and Regia Autonoma a Cuprului Deva or Minvest, and consisted of underground development (adits, drives and cross-cuts), underground diamond and short hole rotary drilling, channel sampling of existing and new underground development, surface rock chip sampling and limited surface diamond drilling. The exploration carried out under Deva Gold ownership can be split into three phases:
● | Exploration managed by consulting company RSG – 2000 to 2003: Exploration was initially conducted by Deva Gold and then from June 2000 to the end of 2003 was managed on behalf of Deva Gold by consultants RSG. The program during this period comprised underground channel sampling of all accessible underground drives and cross cuts, surface channel sampling, limited blast hole sampling and rock chip sampling in the existing open pit on the Central zone. Surface drilling was conducted between January and October 2001. |
● | Additional Consultants – November 2003 to October 2004: Exploration was managed by Deva Gold and consisted of surface reverse circulation (RC) and diamond drilling. This period also saw the involvement of consultants Kvaerner and AMEC Minproc. Kvaerner re-examined the deposit and remodelled the mineral resource in an attempt to define high grade zones based on a series of north-south sections. Whilst the sections cut the overall east-west trend of the orebody, this did not recognize that most of the gold mineralization is hosted by north-south structures and so the resulting calculation understated the mineral resource with an unclassified estimation of some 25 Mt at 2.1 g/t Au. Given the nature of the mineral resource estimation, little can be drawn from the Kvaerner work that followed. |
● | Management by European Goldfields Technical Team: From October 2004, European Goldfields’ management re-examined the deposit data and reports and concluded that, whilst much of the exploration data gathered by RSG of a high quality, neither the deposit controls, particularly higher grade cores to the mineralization, nor its mineralogy and therefore metallurgy were fully understood. In November 2004, the Company commenced a drilling campaign. |
● | Exploration of Existing Dumps: Exploration over the Coranda dumps took place in two phases, with the first phase between 2004-2005, targeting higher-grade oxide material and mineralised Cretaceous strata with vertical RC drill holes. A second exploration phase in 2008 covered the remaining accessible dump areas with vertical RC drill holes and channel lines. |

Geology and mineralization
Geological Setting
The Certej exploitation concession lies within the ‘Golden Quadrilateral’ an area located in the Apuseni Mountains of Transylvania in Romania. This area forms part of the Carpathian-Balkan province of the Tethyan Arc and has historically produced between 20 million ounces (Moz) and 40 Moz of gold. The district hosts numerous known epithermal and mesothermal Ag-Au, Cu-Au and Cu, gold, silver and base metal deposits associated with the Neogene andesitic-dacitic volcanic and sub-volcanic bodies which intrude a variety of lithologies. These rocks are located along three distinct west-northwest trending belts; the Rosia Montana Belt in the north, the Zlatna belt in the centre and the Certej Brad belt, which hosts the Certej deposit, in the south.
The Certej Brad volcanic belt occurs within a major northwest-southeast trending graben which is approximately 20 km long and 10 km wide. The basement in the Certej area on either side of the graben has been mapped as Jurassic basalt. The basalts are commonly spilitically altered on extrusion, resulting in replacement minerals such as carbonate, albite and chlorite. Cretaceous sedimentary rocks within the graben are quartz-rich and are intercalated with black shales. They are interpreted to be of Barremian-Aptian (130Ma to 120Ma) age. Neogene conglomerates, grits, marls and grey shales overlie the Cretaceous sedimentary rocks.
The Certej concession is dominated by extrusive and intrusive andesite. Andesite stocks throughout the area are commonly propylitically altered and surrounded by lenses of extrusive andesite, which blankets the surrounding Neogene sediments. The south-western quarter of the tenement comprises a thicker sequence of Neogene sedimentary rocks. Andesites and associated extrusive are the main host for gold-silver mineralization in the concession with the exception of the Certej deposit.
At the Certej deposit, the sedimentary rock packages are cut by Neogene porphyritic andesites of both intrusive and extrusive origins which have been divided into the ‘Hondol’ and ‘Sacaramb’ types. Both types are of similar age (K-Ar dating gives around 11Ma) and composition except the Sacaramb Andesite contains biotite and is coarser grained. The Baiaga Andesite is interpreted to postdate the Hondol and Sacaramb Andesite and is of similar composition to it, but is typically fine grained. All lithologies are commonly brecciated from crackle type breccias in the andesite to milled polymictic breccias which contain all rock types.
Thrusts and conjugate faulting are the dominant structural elements in the concession area. The Miocene andesites are spatially associated with the intersection of older thrusts and later faults, which are coeval with the andesitic volcanism.
Mineralization
The deposits along the Certej Brad belt are classified as low to medium sulphidation epithermal deposits. The Certej deposit itself formed at mid to shallow crustal, and may be related to a porphyry style system at depth. The deposit is situated within a 2.5 km by 1.5 km magnetic low which is bounded by unaltered biotite andesite to the west, north and east. The magnetic low is likely due to magnetite being replaced by pyrite during hydrothermal alteration. Within the magnetic low, significant gold mineralization has been outlined in a 1,500 metres long zone extending approximately east-west from Dealul Grozii to the NNE-trending Lidia Fault. Within the zone north-northwest trending fault zones, typified by breccias, host disseminated pyrite mineralization.
Drilling
Exploration was initially conducted by Deva Gold and then from June 2000 to the end of 2003 was managed on behalf of Deva Gold by consultants RSG. The program during this period included a surface drilling programme conducted between January and October 2001. In November 2004, a drilling campaign commenced. In total, 647 drill holes totalling 82,812 metres were drilled during the period of European Goldfields’ involvement in the project. Exploration over the Coranda dumps took place in two phases, with the first phase between 2004-2005, targeting higher-grade oxide material and mineralised Cretaceous sedimentary rocks with vertical RC drill holes. A second exploration phase in 2008 covered the remaining accessible dump areas with vertical RC drill holes and channel lines. No drilling information
Sampling and analysis
92 Eldorado Gold Corporation
prior to European Goldfields’ involvement in the project has been used in the estimation of resources due to the lack of quality control when the data were collected. Both RC and diamond drilling methods have been used to define the Certej deposit. Sample weights have been routinely measured for RC drilling on a metre by metre basis as part of the standard RC drilling and sampling procedures. The resultant data has been statistically analysed. Theoretical percentage recoveries have been based on calculating the volume of a hole produced using a 5.25 inch hammer and using a density of 2.4 t/m3 (deposit average) to determine the theoretical sample weight. On this basis, the theoretical weight of a metre sample is 33 kg. RC samples were then sent to the laboratory for drying and pulverising to 85% passing minus 75µm. A 50 g charge is then taken for fire assay analysis by standard industry techniques.
To ensure a high sample quality, stringent data collection QC procedures were applied. The standard QC procedures for the DDH programs included the use of triple tube sample collection in areas of non-optimal ground conditions, the recording of core recovery and the photography of all core prior to sampling. The diamond core was marked off at 1 metre sample intervals and cut lengthways using a diamond saw to produce half-core samples for assay.
Prior to March 2005, all drilling and channel samples were sent to the Gura Rosiei SGS laboratory in Romania. Following March 2005, drillhole and channel samples were submitted to both the Gura Rosiei SGS laboratory in Romania and the Krumovgrad Bulgaria, SGS exploration sample preparation facility, and assayed at the SGS Chelopech laboratory in Bulgaria.
Data verification
The rapid submission of samples from drilling for analysis, and the close scrutiny of procedures by Romanian and expatriate technical staff, provides little opportunity for sample tampering. Equally, given the rigorous umpire assaying via external international laboratories and the regular ‘blind’ submission of international standards to the primary and umpire assay facilities, any misleading analytical data would be readily recognized and investigated.
Reference material for all samples is appropriately retained and stored, including chip trays derived from RC drilling, half-core and photographs generated by DDH, and assay pulps of all submitted samples. Assessment of the data indicates that the assay results are generally consistent with the logged alteration and mineralization, and are entirely consistent with the historical and anticipated tenor of mineralization.
The current QC procedures include the submission of internationally recognized standards, umpire assaying at two internationally recognized laboratories in Canada (ALS Chemex) and Australia (SGS), duplicate and replicate sample analyses and the submission of RC field duplicate samples at a rate of 1:20, with the latter providing a comparison of the total sampling and analytical error.
The accuracy of the gold and silver assay data and the potential for cross contamination of samples during sample preparation has been assessed based on the assay results for the laboratory internal standards and blanks and the Deva Gold submitted Rocklabs standards. RSG considered the gold and silver standards analysed by the SGS Gura Rosiei and Chelopech laboratories are accurate and appropriate for mineral resource estimation studies.
Mineral Resources and Mineral Reserves Estimates
The geology of the Certej locality and deposit is well established and a detailed regional and local model for the mineralization has been put together by European Goldfields and Deva Gold. Detailed drilling, data analysis and modelling have resulted in the development of a robust geological and grade model. The mineral resource estimate is well supported with over 60,000 metres of drilling and 22,000 metres of channel sampling. A notional 0.5 g/t gold lower cut-off grade was used to develop the estimation domain boundaries used to constrain the mineral resource.
2011 Annual information form 93
Geological wire framing and three dimensional modelling of domains has been carried out based on careful mapping of four mineralogical zones, East, Intermediate, Central and West. These have distinct mineralogical signatures and correspondingly distinctive gold deportment. Their boundaries correspond to litho structural features which have also been modelled in three dimensions. Sampling of all of these zones has been representative.
The mineral resources and mineral reserves have been subject to several audits by RSG during the course of the project development. The mineral resources and mineral reserves are categorised to CIM standards.
Analysis has shown that the mineral resource estimation approach using an SMU model calculated using uniform conditioning of ordinarily kriged parent blocks by way of uniform conditioning is valid and a representative way of modelling the Certej mineralization. Comparison of the mineral resource to internally produced polygonal estimates validate the SMU estimate. The mineral resource estimate has been completed several times by RSG with very similar results as well as having been checked internally twice with a less than 3% difference in volume.
Total probable mineral reserves from the open pits are 32.8 Mt at 2.0 g/t for gold and 11.4 g/t for silver, at an approximate gold cut-off grade of 0.8 g/t Au, and 92.2 Mt of waste, for a life of mine strip ratio of 3.1:1 (t:t). 9.7 Mt of waste are used for building roads and pads, 18.7 Mt are used for in-pit dumping in the East pit, and some 63.8 Mt are stored between the North and South dumps. An additional 7.8 Mt of in-pit mineral reserves using a cut-off of 0.6 g/t gold and 14 g/t silver becomes economic to process at $650 per oz. Au and $7.50 per ounce Ag. This lower grade mineral reserve is classified as probable mineral reserve and is expected to be processed at the end of mine life. Existing dumps from historic production contain probable mineral reserves of 6.3Mt at 0.53 g/t Au and 8.9 g/t Ag. This material will be processed at the end of mine life with the lower grade in-pit material. Total mineral reserves of 47 Mt will support a mine life of 16 years.

Properties Acquired from EUROPEAN GOLDFIELDS LIMITED
The table below shows the mineral reserves and resources of the properties acquired through the acquisition of European Goldfields on February 24, 2012. The following is derived from the technical reports filed by European Goldfields and listed under the description of each property. Skouries, Olympias and Certej estimates are as of July, 2011 and Stratoni is as of August 2010. No re-estimates have been done by Eldorado nor have existing estimates been depleted by 2011 production.
The estimation of mineral reserves and mineral resources is a subjective process where the accuracy of any such estimates is a function of the quantity and quality of available data and the assumptions made and judgments used in engineering and geological interpretation, which may be proven to be unreliable. The assumptions and judgments used in such a process may differ, and there is no assurance that if the European Goldfields mineral reserve and mineral resource estimates for Olympias, Skouries, Stratoni and Certej were prepared by Eldorado that the estimates would be the same. Eldorado intends to review the methodology used in preparing the mineral reserve and mineral resource estimates of these European Goldfields properties and update them as appropriate. Accordingly, there is no assurance that the mineral reserve and mineral resource estimates for the European Goldfields properties will not change.
Note that for Olympias and Stratoni all modelled mineralization is economic due to sharp geological contact between mineralized and waste rock and the inherent high grade mineralization.

2011 Annual information form 97
Mineral reserves and resources
Mineral reserves and resources are reported on a 100% basis for each property.
Estimates are based on the definitions adopted by the Canadian Institute of Mining, Metallurgy and Petroleum (you can find the definitions at www.cim.org), and in accordance to the disclosures requirements with Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects (NI 43-101), developed by the Canadian Securities Administrators. As noted above, European Goldfields adopted both JORC and CIM classifications for reporting purposes and other items as equivalent to the European Goldfield property.
About mineral reserves and resources
Estimates of mineral resources include mineral reserves.
A mineral reserve is the part of a measured or indicated mineral resource that can be economically mined, demonstrated by at least a preliminary feasibility study that includes adequate information about mining, processing, metallurgical, economic and other relevant factors that demonstrate (at the time of reporting) that economic extraction can be justified.
Mineral resources are minerals that have reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge. Resources are classified into measured, indicated and inferred.
Mineral resources that have not already been classified as mineral reserves do not have demonstrated economic viability, and there can be no assurance that they will ultimately be converted into mineral reserves.
Understanding estimates
Estimating mineral reserves and resources is a subjective process. Accuracy depends on the quantity and quality of available data and assumptions and judgments made when interpreting it, which may prove to be unreliable.
The cut-off grades for the deposits are based on our assumptions for plant recovery, gold value, mining dilution and recovery, and our estimates for operating and capital costs. We may have to recalculate our estimated mineral reserves and resources based on actual production or the results of exploration.
Fluctuations in the price of gold, production costs or recovery rates can make it unprofitable for us to operate or develop a particular property for a period of time. See page 1 for information about forward-looking information, and page 103 for a discussion of our risk factors.
Estimates are calculated to end of 2011 mining limits and account for ore loss and waste dilution. They are based on the following price assumptions:

Important information for US investors
You will not be able to compare the mineral reserve and resources information in this AIF with similar information from US companies.
The United States Securities & Exchange Commission (SEC) defines a mineral reserve as the part of a mineral deposit that can be economically and legally extracted or produced. It does not recognize the terms measured, indicated and inferred mineral resources (mining terms under NI 43-101), and does not accept them in reports and registration statements.
You should not assume that:
● | the mineral reserves defined in this AIF qualify as reserves under SEC standards |
● | the measured and indicated mineral resources in this AIF will ever be converted to reserves |
● | the inferred mineral resources in this AIF are economically mineable, or will ever be upgraded to a higher category.. |

Notes to the Eldorado Gold mineral reserves and resource estimates
Kişladağ
Modeling
● | used 3D models: lithology models, alteration model, and mineralized or grade shapes |
● | 3D mineralized envelopes, or shells, based on initial outlines derived using Probability Assisted Constrained Kriging (PACK), constrained gold grade interpolation |
● | used a threshold value of 0.20 g/t Au |
● | assays were composited into 5 metre downhole composites |
● | the model was validated by visual inspection, checks for bias and appropriate grade smoothing. |
Grades
● | data analyses demonstrated that the lithologic units within the gold mineralized shell should be treated as separate domains |
● | grades for blocks estimated with a hard boundary between them |
● | distributions do not indicate a problem with extreme gold grades for gold |
● | grades were interpreted by ordinary kriging using a two-pass approach: the first pass required values from a minimum of two holes to interpolate a model grade value |
Mining
● | open pit |
● | designed using Gemcom GEMS software based on a 10 metre bench height with double benching for most pit walls |
● | design based on an optimization using Whittle software |
● | berm width, face angle and bench stack heights vary by sector and rock quality |
● | block model contains expected dilution |
● | and the pit will extend down to a bottom elevation of 370 metres above mean sea level |
Efemçukuru
Modelling
● | create mineralized or grade shapes using new data from the infill drill program and revised structural interpretations of the Kestane Beleni Vein system |
● | 3D shapes based on approximately a 2.0 g/t Au grade threshold and general vein geometry |
● | threshold value was chosen by inspection of histograms and probability curves, and further supported by indicator variography. Areas of narrow or absent above threshold mineralization were included by using a minimum 2 metre interval rule |
the model was validated by visual inspection, checks for bias and appropriate grade smoothing |
Grades
● | extreme grades were examined for gold mainly by histogram and cumulative distribution plots |
● | very high grade outlier assays in the south and middle ore shoots were given a high cap of 200 g/t Au. A 40 g/t Au limit was imposed on north ore shoot assays |
● | an outlier restriction of 35 g/t Au for the south ore shoot and 70 g/t Au for the middle ore shoot (half the original search ranges) prevented over-extrapolation of high grades in areas of less dense drill coverage |
● | assays were composited into 1 metre downhole composites |
● | grades were interpolated by ordinary kriging using a two-pass approach: the first pass required values from at least two holes to interpolate a model grade value |
Mining
● | underground |
● | primary stoping method: cut and fill |
● | for ore widths between 2 and 12 metres: supported mechanized cut and fill |
● | spiral footwall ramps in each of the middle and south ore shoots provide access ore is be hauled by truck to a central ore pass system above the underground crusher before being taken to the surface by conveyor. Paste backfill will be used to fill mined areas |
100 Eldorado Gold Corporation
The mineral resources and mineral reserves lie primarily within the Jinlonggou deposit.
Modelling
● | Jinlonggou block model includes several fault surfaces and mineralized shapes that constrain and control gold grade interpolation |

● | cemented hydraulic back fill is used in mined areas |
Eastern Dragon
Modelling
● | used 3D lode models (#5 and an eastern splay) |
● | drillhole data was prepared as full seam composites containing the true thickness, length averaged values for gold and silver, and gold and silver accumulations (product of grade and thickness) |
● | data analysis showed only limited samples required a top cut (no top cutting was done for silver) |
● | a value of 250 g/t gold was applied to assay data before compositing |
● | the model was validated by visual inspection and checks for bias |
Grades
● | grades were interpolated using ordinary kriging in two dimensions, in 25 metre x 25 metre blocks |
● | interpolation used a two-pass approach: the first pass required four values to interpolate a model grade value |
Mining
open pit:
● | to first mine the upper portion of the deposit |
● | design was constrained by the need to minimize land use in this remote forested region, and by the possible need to use some of the available land as the operation’s tailings impoundment facility underground |
2011 Annual information form 101
● | underground reserves were calculated assuming benching as the main method of extraction using 15 metre spaced sub-levels |
● | ore loss estimated at 5% and dilution estimated at 15% |
Vila Nova
Modelling

Risk Factors
We face a number of risks and uncertainties in our business. Several of them can have a material and adverse effect on our operations and the value of our securities, and we discuss them in this next section.
Financial risks | 103 |
Business and operational risks | 108 |
Risks related to acquisitions | 116 |
Risks related to our common shares | 118 |
Financial risks
Metal price volatility
The profitability of our operations is significantly affected by changes in gold and other metal prices.
The gold and metal price can fluctuate widely and is influenced by many factors beyond our control, including:
● | industrial demand |
● | demand from the jewelry industry |
● | inflation and the expected rate of inflation |
● | strength of the US dollar and other currencies |
● | interest rates |
● | political and economic events (global and regional) |
● | production and cost levels in major gold-producing regions like South Africa and China |
● | speculative activities (causing rapid short-term changes in the price of gold) |
● | official pricing in certain countries |
Between 2006 and the date of this AIF, the price of gold as quoted on the London Bullion Market ranged from a low of $525 to a high of $1,895 per ounce, based on the PM fixing price for gold.
We have used a price range between $850 and $1,250 per ounce Au in the mineral reserve and resource estimates for our Eldorado projects. Using significantly lower gold prices in the reserve calculations and life-of-mine plans, would result in lower mineral reserve and resource estimates, material write-downs of our investment in mining properties and higher amortization, reclamation and closure charges.
If gold prices decline significantly, or decline for an extended period of time, we might not be able to continue our operations, develop our properties, or fulfill our obligations under our permits and licenses, or under our agreements with our partners. This could result in losing our interest in some or all of our properties, or being forced to sell them, which could have a negative effect on our profitability and cash flow.
We currently sell lump iron ore and sinter fines produced at Vila Nova into the Chinese spot market. Spot prices for iron ore fluctuate widely due to the supply and demand factors that influence steel production. At the end of 2008, iron ore spot prices dropped significantly because of the global financial crisis, so we put Vila Nova on care and maintenance. Iron ore prices have since rebounded, and in the fourth quarter of 2010 we re-started trial mining operation at Vila Nova. Vila Nova had high margins for 2011, but if iron ore spot prices drop significantly again, and over a prolonged period of time, we may have to put it back on care and maintenance.
2011 Annual information form 103
Hedging activities
Companies use hedging activities to protect them from fluctuations in the price of gold and other metal, and to minimize the effect that declines in gold and other metal prices can have on results of operations for a period of time.
We currently do not have any gold hedges, but we may hedge in the future. While hedging can protect us from low gold prices, it can also limit the price we can realize on gold that is subject to forward sales and call options (when the market price is higher than the price in a forward sale or call option contract).
We currently do not hedge any other commodity supply, although we may do so from time to time in the future.
We currently do not have any currency hedges. Currency fluctuations can have an adverse effect on our future cash flow, results of operations and financial condition.
Mineral reserve and resource estimates
Mineral reserve and resource estimates are only estimates. We may not realize the levels of gold production indicated.
The proven and probable mineral reserve figures in this AIF are estimates, and may need to be revised based on various factors like:
● | actual production experience |
● | fluctuations in the market price of gold |
● | results of drilling or metallurgical testing |
● | production costs |
● | recovery rates. |
The cut-off grades for the mineral reserves and mineral resources are based on our assumptions (and in the case of European Goldfields property, European Goldfields assumptions) about plant recovery, gold value, mining dilution and recovery, and our estimates (and European Goldfield estimates) for operating and capital costs, which are based on historical production figures. We may have to recalculate our estimated mineral reserve and resources based on actual production or the results of exploration. Fluctuations in the market price of gold, production costs or recovery rates can make it unprofitable for us to develop or operate a particular property for a period of time. If there is a material decrease in our mineral reserve estimates, or our ability to extract the mineral reserves, it could have a material and adverse effect on our future cash flow, results of operations and financial condition.
There are uncertainties inherent in estimating proven and probable mineral reserves and measured, indicated and inferred mineral resources, including many factors beyond our control. Estimating mineral reserves and resources is a subjective process. Accuracy depends on the quantity and quality of available data and assumptions and judgments used in engineering and geological interpretation, which may be unreliable. It is inherently impossible to have full knowledge of particular geological structures, faults, voids, intrusions, natural variations in and within rock types and other occurrences. Failure to identify and account for such occurrences in our assessment of mineral reserves and resource may have a material and adverse effect on our future cash flow, results of operations and financial condition.
There is no assurance that the estimates are accurate, that mineral reserve and resource figures are accurate, or that the mineral reserves or resources can be mined or processed profitably. Mineral resources that are not classified as mineral reserves do not have demonstrated economic viability. You should not assume that all or any part of the measured mineral resources, indicated mineral resources, or an inferred mineral resource will ever be upgraded to a higher category.
Mineral reserve and resource estimate methodology and European Goldfields property
The mineral resources and reserves for Olympias, Skouries, Stratoni, and Certej were prepared by European Goldfields prior to its acquisition by Eldorado and are based on European Goldfields assumptions and estimates. Skouries, Olympias and Certej estimates are as of July, 2011 and Stratoni is as of December, 2010. As of the date hereof, no re-estimates have been done to these estimates and the estimates have not been depleted for 2011 production. There is no assurance that if these mineral
104 Eldorado Gold Corporation
Unless otherwise indicated, the information regarding European Goldfields properties contained in the AIF is based on the scientific and technical data in technical reports prepared for European Goldfields to support the disclosure and other publicly disclosed information of European Goldfields. Furthermore, we have not reviewed in detail the methodology used by European Goldfields in preparing European Goldfields’ mineral reserves and mineral resources included in this AIF and accordingly, there is no assurance that such estimates will not change following our review of the methodology. Although Eldorado has no reason to doubt the accuracy or completeness of the information, there is no assurance that the information will not change and any inaccuracy or material omission in such information could result in unanticipated liabilities or expenses, increase the cost of integrating the companies or adversely affect the operational and development plans of Eldorado and its results of operations and financial condition.
Reporting reserves
There are material differences between the standards and terms used for reporting reserves in Canada and the US.
Mineral reserve and mineral resource estimates for the Kişladağ, Tanjianshan, Jinfeng, White Mountain, Eastern Dragon, Efemçukuru, Perama Hill, Tocantinzinho and Vila Nova include terms that comply with reporting standards in Canada, and certain estimates are based on the reporting requirements of NI 43-101. While the terms mineral resource, measured mineral resource, indicated mineral resource and inferred mineral resource are defined by CIM and must be disclosed according to Canadian securities regulations, the US Securities and Exchange Commission (SEC) does not recognize them under SEC Industry Guide 7 and they are not normally permitted to be used in reports and registration statements filed with the SEC.
Investors should not assume that:
● | any or all of a measured, indicated or inferred resource will ever be upgraded to a higher category or to mineral reserves |
● | any or all of an inferred mineral resource exists or is economically or legally feasible to mine, or will ever be upgraded to a higher category. |
Under Canadian securities regulations, estimates of inferred mineral resources cannot be used as the basis of feasibility or prefeasibility studies.
Other information about our mineral deposits may not be comparable to similar information made public by US domestic mining companies, including information prepared according to Industry Guide 7.
Production and cost estimates
Estimates of total future production and costs for our mining operations are based on our five-year mining plans. These estimates can change, or we might not achieve them, which could have a material and adverse effect on any or all of our future cash flow, results of operations and financial condition.
Our plans are based on our mining experience, reserve estimates, assumptions about ground conditions and physical characteristics of ores (such as hardness and the presence or absence of certain metallurgical characteristics) and estimated rates and costs of production, among other things. Our actual production and costs may be significantly different from our estimates for a variety of reasons, including the risks and hazards discussed above, and:
● | actual ore mined varying from estimates in grade, tonnage and metallurgical and other characteristics |
● | mining dilution |
● | pit wall failures or cave-ins |
● | industrial accidents and environmental incidents |
2011 Annual information form 105
● | equipment failures or not performing to specifications |
● | natural phenomena such as inclement weather conditions, floods, blizzards, droughts, rock slides and earthquakes |
● | encountering unusual or unexpected geological conditions |
● | changes in power costs and potential power shortages |
● | shortages of and timing delays of principal supplies needed for operation, including explosives, fuels, chemical reagents, water, equipment parts and lubricants |
● | litigation |
● | abour availability and other actions by labour at unionized locations |
● | restrictions imposed by government agencies and compliance with government regulations |
● | permitting or licensing issues |
● | political or social activism or unrest |
● | shipping interruptions or delays |
Any of these events could result in damage to mineral properties, property belonging to us or others, interruptions in production, injury or death to persons, monetary losses and legal liabilities. This could cause a mineral deposit to become unprofitable, even if it was mined profitably in the past.
Production estimates for properties not yet in production, or in production and slated for expansion, are based on similar factors (including feasibility studies prepared by our personnel or by third party consultants, in some instances), but it is possible that actual cash operating costs and economic returns will differ significantly from our current estimates. It is not unusual for new mining operations to experience unexpected problems during the start-up phase, and delays in production can often happen.
Any decrease in production, or change in timing of production or the prices we realize for our gold, will directly affect the amount and timing of our cash flow from operations. A production shortfall or any of these other factors would change the timing of our projected cash flows and our ability to use the cash to fund capital expenditures, including spending for our projects.
Infrastructure, energy and other commodities availability and cost
Mining, processing, development and exploration activities depend on adequate infrastructure. Reliable roads, bridges, energy and power sources and water supply are important factors that affect capital and operating costs. If we do not have timely access to adequate infrastructure, there is no assurance that we can start exploiting or developing projects, complete them on a timely basis or at all, that the ultimate operations will achieve the anticipated production volume, or that our construction costs and ongoing operating costs will not be higher than anticipated.
Unusual or infrequent weather phenomena, accidents, sabotage or other events that interfere with the maintaining or providing of adequate infrastructure could also have an adverse effect on our operations and profitability.
Profitability is affected by the market prices and availability of commodities that we use or consume for our operations and development projects. Prices for commodities like diesel fuel, electricity, steel, concrete, and chemicals (including cyanide) can be volatile, and changes can be material, occur over short periods of time and be affected by factors beyond our control. Our operations use a significant amount of energy and depend on suppliers to meet those needs; however, sometimes no alternative source is available. Higher costs for construction materials like steel and concrete, or tighter supplies, can affect the timing and cost of our development projects.
If there is a significant and sustained increase in the cost of certain commodities, we may decide that it is not economically feasible to continue some or all of our commercial production and development activities, and this could have an adverse effect on our profitability.
Higher worldwide demand for critical resources like input commodities, drilling equipment, tires and skilled labour could affect our ability to acquire them and lead to delays in delivery and unanticipated cost increases, which could have an effect on our operating costs, capital expenditures and production schedules.
Further, we rely on certain key third-party suppliers and contractors for equipment, raw materials and services used in, and the provision of services necessary for, the development, construction and
106 Eldorado Gold Corporation
Exploration and development programs
We estimate our current financial resources to be sufficient to support planned exploration and development programs, however, additional capital may be needed for further exploration, development and construction of mineral projects in Brazil, China, Greece, Turkey, Romania and possibly elsewhere. If we decide to proceed to production on a development project, then a significant amount of capital would be needed for project engineering and construction. As a result, the continuing exploration and development of our properties may depend on our ability to obtain financing through joint ventures, debt financing, equity financing or other means. There is no assurance that we will be successful in obtaining such financing at all, or on terms we find acceptable.
Foreign currency
We operate in a number of jurisdictions outside of North America (predominantly Brazil, China, Greece, Turkey and Romania) and incur certain expenses in foreign currencies. We currently receive revenue from operations in US dollars but incur a significant portion of our operating expenses and costs in Canadian dollars, Euro, Lira, Real and RMB, all of which fluctuate in value and are subject to their own country’s political and economic conditions.
We are subject to fluctuations in the exchange rates between the US dollar and these currencies. This can have a material effect on our future cash flow, results of operations and financial condition and lead to higher construction, development and other costs than anticipated. We do not currently hedge currency exchange risks, although we may do so from time to time in the future.
Carrying value of assets
The carrying value of our assets is compared to their estimated fair value to assess how much can be recovered based on current events and circumstances. Our fair value estimates are based on numerous assumptions and the actual fair value could be significantly different than these estimates.
If there are no mitigating valuation factors and we do not achieve our valuation assumptions, or we experience a decline in the fair value of our reporting units, it could result in an impairment charge.
Changes in accounting or financial reporting standards
Changes in accounting or financial reporting standards may have an adverse impact on our financial performance in the future. We have previously reported our financial performance in accordance with Canadian generally accepted accounting principles as set out in the Handbook of the Canadian Institute of Chartered Accountants (“CICA Handbook”). In 2010, the CICA Handbook was revised to require Canadian public companies to adopt IFRS effective January 1, 2011. Accordingly, our financial performance for 2011 and 2010 is reported using IFRS. See our 2011 annual MD&A for information on accounting differences between Canadian GAAP and IFRS.
2011 Annual information form 107
Regulatory requirements
Regulatory requirements have a significant impact on our mining operations, and can have a material and adverse effect on our future cash flow, results of operations and financial condition.
We have operations in a number of jurisdictions outside of North America, mainly in Brazil, China, Greece and Turkey and Romania. The laws in each of these countries are significantly different, and they can change. Mining operations, development and exploration activities are subject to extensive laws and regulations governing among other things:
● | prospecting |
● | development |
● | production |
● | imports and exports |
● | taxes |
● | mineral tenure, land title and land use |
● | labour standards |
● | occupational health |
● | waste disposal |
● | environmental protection and remediation |
● | protection of endangered and protected species |
● | mine safety |
● | toxic substances and other matters |
Mining is subject to potential risks and liabilities associated with pollution and the disposal of waste products from mineral exploration and production. Costs for discovering, evaluating, planning, designing, developing, constructing, operating, closing and remediating our mines and other facilities in compliance with these laws and regulations are significant.
Not complying with applicable laws and regulations can result in enforcement actions that can include corrective measures requiring capital expenditures or the installation of additional equipment, or remedial actions. Parties involved in mining operations may be required to compensate those suffering loss or damage resulting in interruption of mining activities and may face civil or criminal fines or penalties for violating certain laws or regulations.
New laws and regulations, amendments to existing laws and regulations or administrative interpretation, or more stringent enforcement of existing laws and regulations, whether in response to changes in the political or social environment we operate in or otherwise, could have a material and adverse effect on our future cash flow, results of operations and financial condition.
Foreign investments and operations
Most of our activities and investments are in foreign countries including operations and/or exploration and development projects in Brazil, China, Greece, Romania and Turkey.
These investments are subject to risks normally associated with conducting business in foreign countries. Some risks are more prevalent in less developed countries or those with emerging economies, including:
● | uncertain political and economic environments |
● | risks of war and civil disturbances or other risks that can |
● | limit or disrupt a project |
● | restrict the movement of funds |
● | deprive contract rights, or |
● | result in property loss by nationalization or appropriation with or without compensation |
● | risk of adverse changes in laws or policies of particular countries |
● | increases or changes in foreign taxation |
● | delays in or the inability to obtain necessary government permits, approvals and consents |
● | limitations on ownership and repatriation of earnings |
● | possible imposition of foreign membership limits |
● | foreign exchange controls and currency devaluations |
108 Eldorado Gold Corporation
● | import and export regulations, including restrictions on exporting gold |
● | disadvantages of competing against companies from countries that are not subject to Canadian and US laws, including laws relating to corrupt foreign practices and restrictions on the ability to pay dividends offshore |
● | loss from disease and other potential endemic health issues |
● | unfavourable social benefits and labour requirements |
Although we are not currently experiencing any significant or extraordinary problems arising from these risks, there is no assurance that we will not experience them in the future.
China may be considered an example of these risks. We have three mines in China, and one under construction. The Chinese government plays a significant role in regulating the mining industry by instituting industrial policies. It also exercises significant control over the country’s economic growth by allocating resources, controlling foreign currency-denominated obligations, controlling foreign investment and provisions in its Foreign Investment Guidelines for Foreign Investment. China’s significant growth in the past 20 years has been uneven geographically and in different sectors of the economy, and the Chinese government has responded by implementing various measures to control the pace and location of economic growth. These measures can have a material and adverse effect on our results of operations.
Companies with a foreign ownership component operating in China may be operating under a different framework than what is imposed on domestic Chinese companies. The Chinese government currently allows foreign investment in certain mining projects under central government guidelines, but any changes to the guidelines can have a material and adverse effect on our results of operations.
Companies need certain approvals to export gold from China, and there is no assurance we can obtain them. Like most gold producers there, we sell our gold through the Shanghai Gold Exchange, which serves as a spot market for its members since gold is traded at market price and our dore is sold to local refineries. There is no assurance that these prices will continue to reflect international market prices.
Foreign exchange transactions in China (including the repatriation of investment returns and capital) continue to be subject to foreign exchange controls. We can repatriate our profits and dividends in foreign currency but cannot repatriate our capital, unless it has been approved by the Chinese State Administration of Foreign Exchange.
Another example of these risks is Greece. Our acquisition of European Goldfields increased our presence in Greece significantly. In 2011, the Greek economy experienced a severe downturn that is ongoing. In addition, the implementation of a stabilization program agreed to by the Greek government has been the source of protest and civil unrest in the country. The state of the Greek economy has raised concerns about the risks of Greece defaulting on its debt and certain measures are being considered or are being implemented to address the debt situation. This is an unusual position for a Eurozone state member to be in and the long and short term effects of such a position are relatively unknown.
There is no assurance that the current economic situation could not get worse or that Greece does not adopt regulatory or political changes which may negatively affect our current and future operations and plans in Greece.
Permits, licenses and approvals
In countries where we have operations or carry out exploration activities, the mineral rights or certain portions of them are owned by the relevant governments. These governments have entered into contracts with us, or granted permits or concessions that allow us to carry out operations or development and exploration activities there, but government policy could change. Any change that affects our rights to conduct these activities could have a material and adverse effect on our results of operations.
In addition, mineral exploration and mining activities can only be conducted by entities that have obtained or renewed exploration or mining permits and licenses in accordance with the relevant mining laws and regulations. The duration and success of each permitting effort are contingent upon many factors we do not control. In the case of foreign operations, governmental approvals, licenses and permits are, as a practical matter, subject to the discretion of the applicable governments or governmental officials. There may be delays in the review process. There is no guarantee that we will be granted the necessary
2011 Annual information form 109
All mining projects require a wide range of permits, licenses and government approvals and consents. It’s not certain that we’ll be granted these at all, or in a timely manner. If we do not receive them for our mineral projects and mines, or are unable to maintain them, it could have a material and adverse effect on the results of our operations.
Joint venture partners
Mining projects are often conducted through an unincorporated joint venture or an incorporated joint venture company. Joint ventures often require unanimous approval of the parties or their representatives for certain fundamental decisions like an increase (or decrease) in registered capital, a merger, division, dissolution, amendment of the constating documents, and pledge of the joint venture assets, which means that each party to the joint venture has a right to veto any of these decisions, which could lead to a deadlock.
Our interests in Tanjianshan, Jinfeng, White Mountain and Eastern Dragon are through joint venture companies established under and governed by the laws of China. Some of our joint venture partners in China are state-sector entities and, like other state-sector entities and their actions and priorities may be dictated by government or other policies instead of purely commercial considerations.
Exploration efforts
Gold and other metal exploration is highly speculative in nature, involves many risks and is often not productive; there is no assurance that we’ll be successful in our gold exploration efforts.
Our ability to increase mineral reserves is dependent on a number of factors, including the geological and technical expertise of our management and exploration teams, the quality of land available for exploration and other factors. Once gold mineralization is discovered, it can take several years of exploration and development before production is possible, and the economic feasibility of production can change during that time.
Substantial expenditures are required to:
● | carry out drilling to establish proven and probable mineral reserves and determine the optimal metallurgical process to extract the metals from the ore |
● | build mining and processing facilities for new properties. |
There is no assurance that our exploration programs will expand our current mineral reserves or replace them with new mineral reserves. Failure to replace or expand our mineral reserves could have an adverse effect on us.
Costs of development projects
As development projects are uncertain, actual cash operating costs and economic returns can differ significantly from those estimated for a project prior to production.
Mine development projects, including Eastern Dragon, Tocantinzinho, Perama Hill, Skouries, Olympias, and Certej typically require a number of years and significant expenditures during the development phase before production is possible.
Development projects depend on successfully completing feasibility studies and environmental assessments, obtaining the necessary government permits and receiving adequate financing. Economic feasibility is based on several factors including:
● | estimated mineral reserves |
● | anticipated metallurgical recoveries |
● | environmental considerations and permitting |
● | future gold prices |
● | anticipated capital and operating costs for the projects |
● | timely expectation of development plan. |
110 Eldorado Gold Corporation
● | Development projects have no operating history to base estimated future production and cash operating costs on. With development projects in particular, estimates of proven and probable mineral reserves and cash operating costs are largely based on: |
● | interpreting the geologic data obtained from drill holes and other sampling techniques |
● | feasibility studies that derive estimated cash operating costs based on |
● | the expected tonnage and grades of ore to be mined and processed |
● | the configuration of the ore body |
● | expected recovery rates of gold from the ore |
● | estimated operating costs |
● | anticipated climate conditions and other factors. |
It is therefore possible that actual cash operating costs and economic returns will differ significantly from what we estimated for a project before starting production.
Many events could affect the profitability or economic feasibility of a project, including the following, among others:
● | unanticipated changes in grade and tonnage of ore to be mined and processed |
● | unanticipated adverse geotechnical conditions |
● | unanticipated operational problems |
● | unanticipated metallurgical recovery problems |
● | incorrect data on which engineering assumptions are made |
● | costs of constructing and operating a mine in a specific environment |
● | availability of labour |
● | availability and costs of processing and refining facilities |
● | availability of economic sources of power |
● | adequacy of water supply |
● | availability of surface tenure to locate processing and refining facilities |
● | adequate access to the site, including competing land uses (such as agriculture and illegal mining) |
● | unanticipated transportation costs |
● | government regulations (including regulations with respect to prices, royalties, duties, taxes, permitting, restrictions on production, quotas on exportation of minerals, as well as the costs of protection of the environment and agricultural lands) |
● | fluctuations in gold prices |
● | accidents, labour actions and force majeure events |
● | community and non-governmental organizational action. |
It’s not unusual for new mining operations to experience unexpected problems during the start-up phase, and delays can often happen when production begins. In the past, we have adjusted our estimates based on changes to our assumptions and actual results.
Our production and capital and operating cost estimates for development projects are based on certain assumptions. We use these estimates to establish our mineral reserve estimates but our cost estimates are subject to significant uncertainty as described above. Actual results for our projects will likely differ from current estimates and assumptions, and these differences can be material. The experience we gain from actual mining or processing operations can also identify new or unexpected conditions that could reduce production below our current estimates, or increase our estimated capital or operating costs. If actual results fall below our current estimates, it could have a material and adverse effect on our business, results of operations, financial condition and liquidity.
Additional mineral reserves
Because mines have limited lives based on proven and probable mineral reserves, we must continually replace and expand our mineral reserves and any necessary associated surface rights as our mines produce gold.
The ability to maintain or increase annual production of gold and other metals will depend significantly on:
● | our mining operations at Kişladağ, Efemçukuru, Tanjianshan, Jinfeng, White Mountain and Stratoni |
● | our development of Eastern Dragon, Tocantinzinho, Perama Hill, Skouries, Olympias, and Certej |
● | our ability to conduct successful exploration efforts |
2011 Annual information form 111
● | our ability to develop new projects and make acquisitions. |
Operational risks and hazards
Our operations face a number of risks and hazards including among other things:
● | environmental hazards |
● | discharge of pollutants or hazardous chemicals |
● | industrial accidents and injuries |
● | failure of processing and mining equipment |
● | labour disputes and labour shortages |
● | problems or delays in supply |
● | changes in the regulatory environment |
● | unusual or unexpected geologic formations or other geological or grade problems |
● | unanticipated changes in metallurgical characteristics and gold recovery |
● | unanticipated ground or water conditions |
● | cave-ins, pit wall failures, flooding, rock bursts and fire |
● | periodic interruptions due to inclement or hazardous weather conditions |
● | other acts of God |
● | unfavourable operating conditions |
● | bullion losses |
● | our ability to identify additional mineral resources at existing properties. |
These risks could result in damage or destruction of mineral properties or processing facilities, personal injury or death, loss of key employees, environmental damage, delays in mining, monetary losses and possible legal liability. These liabilities can be very costly and could have a material adverse effect on our future cash flow, results of operations and financial condition.
From time to time we may hire contractors and subcontractors for our operations, and there is a risk that they could experience labour disputes or become insolvent, and this could have an adverse effect on our operations and profitability.
In the context of environmental protection permitting, including the approval of reclamation plans, we are required comply with existing laws and regulations and other standards that may entail greater or lesser costs and delays depending on the nature of the activity to be permitted and the interpretation of the laws and regulations implemented by the permitting authority. The failure to obtain or renew certain permits, or the imposition of extensive conditions upon certain permits, could have a material adverse effect on our business, operations and financial condition.
We expend significant resources, to comply with environmental regulations and permitting requirements, and we expect to continue to do so in the future. Failure to comply with applicable environmental laws may result in injunctions, damages, suspension or revocation of permits and imposition of penalties. There can be no assurance that we have been or will be at all times in complete compliance with such laws or permits, that compliance will not be challenged or that the costs of complying with current and future environmental laws and permits will not materially or adversely affect our future cash flow, results of operations and financial condition.
It is possible that future regulatory developments, such as increasingly strict environmental protection laws, regulations and enforcement policies, and claims for damages to property and persons resulting from our operations, could result in additional substantial costs and liabilities, restrictions on or suspension of our activities and delays in the exploration of and development of our properties.
Environmental hazards
There may be environmental hazards at our mines or projects that we are unaware of. We may be liable for any associated losses, or be forced to do extensive remedial cleanup or pay for governmental remedial cleanup, even if the hazards were caused by previous or existing owners or operators of the property, past or present owners of adjacent properties or by natural conditions. The costs of any cleanup could have a material and adverse effect on our operations and profitability.

Financing Risks
We entered into secured credit facilities of up to $280 million with certain lenders in October 2011. For further information on the credit facility, please see “About Eldorado - Key milestones in our history”, see page 4. This credit facility is secured by the shares of SG Resources and Tüprag, wholly owned subsidiaries of the company. This agreement may involve restrictive covenants in certain situations which could limit our operating flexibility going forward.
Furthermore, any drawdown on the credit facilities will introduce interest costs and interest rate risk to Eldorado, as our borrowing costs will fluctuate depending on prevailing interest rates at the time we access the credit facilities, which may have an adverse effect on our future profitability. While neither our articles nor our by-laws limit the amount of indebtedness that we may incur, the level of our indebtedness from time to time could impair our ability to obtain additional financing in the future on a timely basis, or at all, and to take advantage of business opportunities that may arise, thereby potentially limiting our operational flexibility as well as our financial flexibility.
Full compliance at all times
Our activities are subject to extensive federal, provincial, state and local laws and regulations governing environmental protection and employee health and safety. We must obtain government permits and provide associated financial assurance to conduct certain activities. We are also subject to various conditions related to reclamation that are imposed under federal, state or provincial air, water quality and mine reclamation rules and permits.
We have budgeted for future capital and operating expenditures to obtain such permits and maintain compliance with these environmental, health and safety laws, however, any changes to these laws in the future could have an adverse effect on our financial condition, liquidity or results of operations and could delay our ability to obtain such permits.
If these laws are not complied with, we may face injunctions, damages and penalties, or our permits could be suspended or revoked. There is no assurance that we have been, or will be, in compliance with environmental, health and safety laws at all times, that our compliance will not be challenged, or that the cost of complying with current or future laws will not have a material and adverse effect on our future cash flow, results of operations and financial condition.
Insurance
Where practical, a reasonable amount of insurance is maintained against risks in the operation of our business, but coverage has exclusions and limitations. There is no assurance that the insurance will be adequate to cover any liabilities, or that it will continue to be available, and at terms we believe are economically acceptable.
There are some cases where coverage is not available, or we believe it is too expensive relative to the perceived risk.
Competition
We operate in a competitive industry and compete with other, better established companies that have more financial resources, operational experience and technical capabilities than we do. We face strong competition from other mining companies that are acquiring properties that are producing or capable of producing metals.
We may be unable to acquire attractive mining properties, or do so on terms we consider acceptable. This could have a material and adverse effect on our revenues, operations and financial condition.
Key personnel
Eldorado depends on a number of key personnel, including Paul N. Wright, our President and Chief Executive Office, Norman S. Pitcher, our Chief Operating Officer, and Fabiana E. Chubbs, our Chief Financial Officer. We do not have key man life insurance. Employment contracts are in place with each of these executives, however losing any of them could have an adverse effect on our operations.
2011 Annual information form 113
We need to continue implementing and enhancing our management systems and recruiting and training new employees to manage our growth effectively. We have been successful in attracting and retaining skilled and experienced personnel in the past, and expect to be in the future, but there is no assurance that we will be.
Good employee relations
We depend on our workforce to explore for mineral reserves and resources, develop our projects and operate our mines. We have programs to recruit and train the necessary manpower for our operations, and we work hard at maintaining good relations with our workforce to minimize the possibility of strikes, lockouts and other stoppages at our work sites. A prolonged labour disruption at any of our mines or projects could have a material and adverse effect on our overall operations.
Title to our mineral properties
We have investigated title to all of our mineral properties and, to the best of our knowledge title to all of our properties is in good standing. It’s possible, however, that any of our properties may be subject to prior unregistered agreements or transfers, and title may be affected by undetected defects.
There could be valid challenges to the title of any of our properties and, if successful, they could impair development and/or operations at our mines or projects. There is no assurance that title to any of our properties will not be challenged.
New laws and regulations, or amendments to laws and regulations relating to mineral tenure and land title and usage, including expropriations and deprivations of contractual rights, if proposed and enacted, may affect our rights to our mineral properties. There is no assurance that we will be able to operate our properties as currently operated or permitted or that we will be able to enforce our rights with respect to our properties.
Litigation risks
All industries, including the mining industry, are subject to legal claims that are with and without merit.
In addition to the litigation in Turkey (see pages 21 and 26) and the administrative proceedings with the European Commission (see page 86), we are involved in various routine legal and regulatory proceedings. It is unlikely that the final outcome of these routine proceedings will have a material and adverse effect on our financial condition or results of operations; however, defense and settlement costs can be substantial, even for claims that are without merit. Due to the inherent uncertainty of the litigation process and dealings with regulatory bodies, there is no assurance that any legal or regulatory proceeding will be resolved in a manner that will not have a material and adverse effect on our future cash flow, results of operations or financial condition.
Health, Safety and Community Relations and Action
Our operations are subject to various health and safety laws and regulations that impose various duties on our operations relating to, among other things, worker safety and surrounding communities. These laws and regulations also grant the authorities broad powers to, among other things, close unsafe operations and order corrective action relating to health and safety matters. The costs associated with the compliance of such health and safety laws and regulations may be substantial and any amendments to such laws and regulations, or more stringent implementation thereof, could cause additional expenditure or impose restrictions on, or suspensions of, our operations. We have made, and expect to make in the future, significant expenditure to comply with the extensive laws and regulations governing the protection of the environment, waste disposal, worker safety, mine development and protection of endangered and other special status species, and, to the extent reasonably practicable, create social and economic benefit in the surrounding communities.
As a mining business, we may come under pressure in the jurisdictions in which we operate, or will operate in the future, to demonstrate that other stakeholders (including employees, communities surrounding operations and the countries in which they operate) benefit and will continue to benefit from our commercial activities, and/or that we operate in a manner that will minimize any potential damage or disruption to the interests of those stakeholders. We currently maintains good relations with local communities in the areas in which we operate and have a demonstrable track record of promoting community and social relations activities for the benefit of local communities. However, we may face
114 Eldorado Gold Corporation
opposition with respect to our current and future development and exploration projects which could materially adversely affect our business, results of operations and financial condition.
Further, certain non-governmental organizations (NGOs), some of which oppose globalization and resource development, are often vocal critics of the mining industry and its practices, including the use of hazardous substances in processing activities. Adverse publicity generated by such NGOs or others related to extractive industries generally, or our operations specifically, could have an adverse effect on our reputation and financial condition and may impact our relationship with the communities in which we operate. They may install road blockades, apply for injunctions for work stoppage and file lawsuits for damages. These actions can relate not only to current activities but also historic mining activities by prior owners and could have a material, adverse effect on our operations.
We may also be held responsible for the costs of addressing contamination from of current or former activities and could be held liable for exposure to hazardous substances. The costs associated with such responsibilities and liabilities may be significant.
We seek to mitigate this risk by our commitment to operate in a socially responsible manner. However, there can be no guarantee that our efforts in this respect will mitigate this potential risk.
Tax Matters
Our tax residency and the tax residency of our subsidiaries are affected by a number of factors, some of which are outside of our control, including the application and interpretation of the relevant tax laws and treaties. If we or our subsidiaries are ever assessed to a be non-tax resident in the jurisdictions that we or our subsidiaries report or are otherwise assessed, we may be liable to pay additional taxes. In addition, we have entered into various arrangements regarding the sale of mineral product which may be subject to unexpected tax treatment. If such taxes were to become payable, this could have a material adverse effect on our business, results of operations and financial condition.
New laws and regulations or amendments to laws and regulations relating to tax laws or tax agreements with governmental authorities, if proposed and enacted, may affect our current financial condition. There is no assurance that our current financial condition will not change in the future due to such changes.
Risks relating to the global economy
Recent market events and conditions, including disruptions in the international credit markets and other financial systems and deteriorating global economic conditions, could increase the cost of capital or impede our access to capital.
Global financial crisis
The global credit markets have experienced serious disruption beginning in 2007 because of declining residential property values, defaults and delinquencies in the residential mortgage market and a decline in the credit quality of mortgage-backed securities. These problems led to a slowdown in sales in the residential housing market, declining housing prices, delinquencies in non-mortgage consumer credit and general decline in consumer confidence.
Conditions worsened in 2008 and have continued to be volatile, causing a loss of confidence in the broader global credit and financial markets and resulting in the collapse of, and government intervention in, major banks, financial institutions and insurers, creating a climate of greater volatility, less liquidity, widening of credit spreads, a lack of price transparency, higher credit losses and tighter credit conditions. Notwithstanding various actions by governments, concerns about the general condition of the capital markets, financial instruments, banks, investment banks, insurers and other financial institutions caused the broader credit markets to further deteriorate and stock markets to decline substantially.
These disruptions in the credit and financial markets have had a significant, material and adverse effect on a number of financial institutions, and limited access to capital and credit for many companies. Although there has been some recovery, global credit and equity markets remain unstable. Recent economic events in Europe (including Greece) starting in 2011 have created further uncertainty in global financial and equity markets. (See discussion above of Greek economy under “Foreign investments and operations”). There is no certainty that ongoing disruptions and their effects have ended and will not continue to affect the markets. These or similar disruptions could make it more difficult for us to obtain capital and financing for our operations, or increase the cost of it, among other things. If we do not raise
2011 Annual information form 115
capital when we need it, or access it on reasonable terms, it could have a material and adverse effect on our business, financial condition and results of operations.
These and other related factors can lead to lower longer term asset values, which can result in impairment losses. High levels of volatility and market turmoil could have an adverse effect on our operations and the price of our common shares.
Liquidity
We are exposed to liquidity risks in meeting our operating and capital expenditure requirements if we cannot maintain our cash positions, or appropriate financing is not available.
We may be unable to secure loans and other credit facilities in the future, and on terms we believe are favourable.
The current global financial conditions resulted in many financial institutions going into bankruptcy or being rescued by government authorities. Any cash deposits we have with financial institutions are therefore at risk.
Risks related to acquisitions
Impact of acquisitions on our growth and financial condition
We are actively pursuing opportunities to acquire advanced exploration, development and production assets that are consistent with our acquisition and growth strategy. From time to time, we may acquire securities of, or an interest in, companies and we may enter into acquisitions or other transactions with other companies.
Transactions involving acquisitions have inherent risks, including:
● | accurately assessing the value, strengths, weaknesses, contingent and other liabilities and potential profitability of potential candidates |
● | ability to achieve identified and anticipated operating and financial synergies |
● | unanticipated costs |
● | diversion of management attention from existing business |
● | potential loss of our key employees or the key employees of any business we acquire |
● | unanticipated changes in business, industry or general economic conditions that affect the assumptions underlying the acquisition |
● | decline in the value of acquired properties, companies or securities |
● | the possibility that indemnification agreements with sellers (if any) may be unenforceable or insufficient to cover potential liabilities. |
Any of these factors or other risks could result in us not realizing the benefits anticipated from acquiring other properties or companies, and could have a material and adverse effect on our financial condition and our ability to grow.
Completing an acquisition
Although we actively seek acquisition opportunities that fit with our acquisition and growth strategy, we are not certain that we will be able to identify more suitable candidates that are available at a reasonable price, complete any acquisition, or integrate any business into our operations successfully. Acquisitions can involve a number of special risks, circumstances or legal liabilities, which could have a material and adverse effect on our results of operations and financial condition.
Acquisitions may be made by using available cash, incurring debt, issuing common shares or other securities, or any combination of these. This could limit our flexibility to raise capital, to operate, explore and develop our properties and make other acquisitions, and it could further dilute and decrease the trading price of our common shares. When we evaluate a potential acquisition, we cannot be certain that we will have correctly identified and managed the risks and costs inherent in that business.
We have discussions and engage in other activities with possible acquisition targets from time to time, and each of these activities could be in a different stage of development. There is no assurance that any potential transaction will be completed and integrated with our operations successfully. If we do not
116 Eldorado Gold Corporation
successfully manage our acquisition and growth strategy, it could have a material and adverse effect on our business, results of operations and financial condition.
Evaluating the merits or risks
It is possible that shareholders may not have the right to evaluate the merits or risks of any future acquisition, except as required by applicable laws and stock exchange rules.
Integration of European Goldfields
Eldorado acquired European Goldfields with the expectation that the acquisition would result in increased production growth at attractive cash costs to Eldorado. This expectation is partly based on presumed synergies from consolidation and successful construction or expansion of mines at European Goldfields’ development projects.
These anticipated benefits will depend in part on whether the operations, systems, management and cultures of each of European Goldfields and Eldorado can be integrated in an efficient and effective manner and whether the expected bases or sources of synergies do in fact produce the benefits anticipated. Most operational and strategic decisions, and certain staffing decisions, with respect to Eldorado post-acquisition have not yet been made and may not have been fully identified. These decisions and the integration of Eldorado and European Goldfields will present challenges to management, including the integration of systems and personnel of the two companies, and special risks, including possible unanticipated liabilities, significant one-time write-offs or restructuring charges, unanticipated costs and the loss of key employees. There can be no assurance that there will be operational or other synergies realized by Eldorado, or that the integration of Eldorado’s and European Goldfields’ operations, systems, management and cultures will be timely or effectively accomplished, or ultimately will be successful in increasing earnings and reducing costs. In addition, synergies assume certain long-term realized gold and other metal prices. If actual prices are below such assumed prices, this could adversely affect the synergies to be realized.
Expanded Portfolio of Projects
As part of our strategy, we will continue our efforts to develop new projects and will have an expanded portfolio of such projects as a result of our acquisition of European Goldfields. We may not realize the benefits of our newly acquired projects. A number of risks and uncertainties are associated with the development of these types of projects, including political, regulatory, design, construction, labour, operating, technical and technological risks, uncertainties relating to capital and other costs and financing risks.
We may be subject to significant permitting and completion risks and capital cost increases associated with our expanded operations and our expanded portfolio of projects.
If there are significant delays in the permitting or completion of projects and when they commence producing on a commercial and consistent scale, and/or their capital costs are significantly higher than estimated, these events could have a significant adverse effect on our results of operations, cash flow from operations and financial condition.
As a consequence of the European Goldfields acquisition, we will be subject to significant additional capital requirements associated with our expanded operations and expanded portfolio of development projects. Significant permitting and regulatory work remains going forward in order to bring European Goldfields’ exploration and development projects into production. Actual capital costs necessary to develop the projects could be significantly above European Goldfields’ estimates. Such capital cost overruns could have a significant adverse effect on our financial condition.
Reliability of disclosure
Unless otherwise indicated herein, all historical information regarding European Goldfields and the properties that we acquired pursuant to our acquisition of European Goldfields, including financial information and mineral reserves and resources, has been derived from European Goldfields’ publicly disclosed information. Although we have no reason to doubt the accuracy or completeness of European Goldfields’ publicly disclosed information, any inaccuracy or material omission in European Goldfields’ publically disclosed information, including that information contained in this AIF, could result in
2011 Annual information form 117
unanticipated liabilities or expenses, increase the cost of integrating the companies or adversely affect our operational and development plan and our results of operations and financial condition
Furthermore, we have not reviewed in detail the methodology used by European Goldfields in preparing European Goldfields’ mineral reserves and mineral resources included in this AIF and accordingly, there is no assurance that such estimates will not change following our review of the methodology.
Risks related to our common shares
Issuing more equity
Future Acquisitions could be made through the issuance of equity. A number of existing agreements provide for additional issues, and future agreements may as well. Additional funds may be needed for our exploration and development programs and potential acquisitions which could be raised through equity. Issuing more equity securities can substantially dilute the interests of our shareholders. Issuing substantial amounts of our securities, or making them available for sale, could have an adverse effect on the prevailing market prices for our securities. A decline in the market price could hamper our ability to raise additional capital through the sale of securities.
Price and volume fluctuations
The capital markets have experienced a high degree of volatility in the trading price and volume of shares sold over the past few years. Many companies have experienced wide fluctuations in the market price of their securities that have not necessarily related to their operating performance, underlying asset values or prospects. There is no assurance that the price of our securities will not be affected.
In the past, shareholders have instituted class action lawsuits against companies that have experienced volatility in their share price. Class action lawsuits can result in substantial costs and divert management’s attention and resources, which could significantly harm our profitability and reputation.
Shareholders who hold our common shares through Chess Depository Receipts (CDIs) may be subject to additional risks. The CDI market may not be as liquid because there are fewer CDIs listed on the ASX than the number of common shares trading on the TSX and NYSE. This can reduce the volume of CDIs that can be bought and sold on the ASX, and affect the speed of any trading activity. Any reduced liquidity may cause the CDIs to trade at a discount to our shares; however CDI holders can convert their CDIs into common shares and trade them on the TSX and NYSE.
Dividends
While we have initiated a policy of payment dividends on our common shares, there is no certainty as to the amount of any dividend or that any dividend may be declared in the future.
Corporate governance requirements
We comply with corporate governance guidelines and disclosure standards that apply to Canadian companies listed on the TSX, and with corporate governance standards that apply to us as a foreign issuer listed on the NYSE and registered with the SEC in the US.
Although we substantially comply with NYSE’s corporate governance guidelines, we are exempt from certain NYSE and Australian Securities and Investment Commission (ASIC) requirements because we comply with Canadian corporate governance requirements. We may from time to time seek other relief from corporate governance and exchange requirements and securities laws from the NYSE, ASX and other regulators.
Non-Canadian residents who hold our common shares (directly or indirectly through CDIs) may not be aware that our corporate and securities laws may be different than those of the ASIC.
Sarbanes-Oxley Act
We document and test our internal control procedures to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act (SOX). SOX requires management to do an annual assessment of our internal controls over financial reporting, and for our external auditors to conduct an independent assessment of their effectiveness.
118 Eldorado Gold Corporation
Our internal controls over financial reporting may not be adequate, or we may not be able to maintain them as required by SOX. We also may not be able to maintain effective internal controls over financial reporting on an ongoing basis, if standards are modified, supplemented or amended from time to time.
If we do not satisfy the SOX requirements on an ongoing and timely basis, investors could lose confidence in the reliability of our financial statements, and this could harm our business and have a negative effect on the trading price of our common shares or the market value of our other securities.
If we do not implement new or improved controls, or experience difficulties in implementing them, it could harm our operating results or we may not be able to meet our reporting obligations. There is no assurance that we’ll be able to remediate material weaknesses, if any are identified in future periods, or maintain all of the necessary controls to ensure continued compliance. There is also no assurance that we’ll be able to retain personnel who have the necessary finance and accounting skills because of the increased demand for qualified personnel among publicly traded companies.
Our recent acquisitions and any other acquisition we make in the future can pose challenges in implementing the required processes, procedures and controls in the new operations. Any companies we acquire may not have disclosure controls and procedures or internal controls over financial reporting that are as thorough or effective as those required by the securities laws that currently apply to us.
If any of our staff fail to disclose material information that is otherwise required to be reported, no evaluation can provide complete assurance that our internal controls over financial reporting will detect this. The effectiveness of our controls and procedures could also be limited by simple errors or faulty judgments. Continually enhancing our internal controls is important, especially as we expand and the challenges involved in implementing appropriate internal controls over financial reporting will increase. Although we intend to devote substantial time to ensuring ongoing compliance, and incurring the necessary costs associated with this, we are not certain that we will be successful in complying with section 404 of SOX.
If any of the events or risk factors described occurs, it could have a negative effect on our business, financial condition or results of operations, and the market price of our securities could decline and investors could lose all or part of their investment.

Dividend policy
The board established a dividend policy in May 2010 and declared our first dividend of Cdn$0.05 per common share. We expect to pay two dividends per year. Any dividend payment is expected to be derived from a dividend fund calculated on an amount, determined at the discretion of the Directors at the time of any decision to pay a dividend, multiplied by the number of ounces of gold sold by Eldorado in the preceding two quarters. In 2011, the Board amended the dividend policy to provide additional step-ups as the average realized gold price increases.
The amount of the dividend fund will be divided among all the issued Eldorado common shares to yield the dividend payable per share. Accordingly, the calculation of any dividend, if declared, will also be subject to increases or decreases dependent upon, among other things, the past and prevailing gold prices.
On June 18, 2010 we paid an inaugural dividend of Cdn$0.05 per common share. In 2011, we paid semi-annual dividends of Cdn$0.05 per common share on February 25, 2011 and $0.06 per common share on August 26, 2011.

Governance
Management and the board of directors are committed to good governance practices.
We apply the highest standards of legal and ethical conduct, and believe in the importance of full, accurate, clear and timely disclosure, and in communicating openly with all of our stakeholders.
We comply with corporate governance guidelines and disclosure standards that apply to Canadian companies listed on the Toronto Stock Exchange (TSX), and with the corporate governance standards that apply to us as a foreign issuer listed on the New York Stock Exchange (NYSE) and registered with the SEC in the US. Eldorado Chess Depository Interests trade on the Australian Securities Exchange (ASX) under the symbol EAU and the Company complies with the required corporate governance regulations of the Australian Securities and Investment Commission, subject to certain exemptions granted to Eldorado upon the listing of the CDIs.
Ethical business conduct
Our code of business conduct and ethics promotes integrity and deters wrongdoing by setting out the legal, ethical and regulatory standards we follow in all of our activities. The code applies to our directors, officers, employees and contractors and reinforces our unwavering commitment to ethical business conduct. Complying with the code and maintaining high standards of business conduct are mandatory, and the board relies on the oversight of our internal controls to monitor compliance with the code. Our code is available on our SEDAR profile at www.sedar.com.
Our board of directors oversees management, who are responsible for the day to day conduct of our business.
The board is responsible for:
● | acting in good faith in our best interests |
● | exercising care, diligence and skill in carrying out its duties and responsibilities |
● | meeting its obligations under the Canada Business Corporations Act, our articles and our bylaws, and any other relevant legislation and regulations governing our business. |
The board has adopted a written mandate, which is available on our website and which describes its responsibility for stewardship. The board carries out its mandate directly or through its committees, which are composed of 100% independent directors.
Directors
According to our articles and bylaws, we must elect between three and 20 directors at every annual general meeting to serve for a one-year term or until a successor is elected or appointed.
The board has decided that nine directors will be elected to the board in 2012. The CBCA requires at least 25% of our directors to be Canadian residents.

None of our directors or executive officers has personally or is (or has been within the last 10 years) a director or executive officer of any company (including ours) that has become bankrupt, made a proposal under legislation relating to bankruptcy or insolvency, was subject to or instituted any proceedings, arrangement or compromise with creditors, had a receiver, receiver manager or trustee appointed to hold its assets, was subject to any cease trade order or order similar to a cease trade order or any other order that denied the Company access to any exemption under securities laws that was in effect for more than 30 days, has entered into a settlement agreement with a securities regulatory authority, or was subject to other penalties or sanctions imposed by a court or regulatory body relating to securities legislation or that would be likely to be considered by a reasonable shareholder in making an investment decision while the director or executive officer held their position or after ceasing to hold that position but where the order, penalty or sanction related to an event that occurred while they were in that position.
Conflicts of interest
To the best of our knowledge, and other than disclosed in this AIF, we are not aware of any existing or potential conflicts of interest between us or any of our directors or officers, except that some of them serve as directors and officers of other public companies.

Our directors and officers are aware of the laws governing accountability of directors and officers for corporate opportunity. They understand they are required to disclose any conflicts of interest under the CBCA and are expected to govern themselves to the best of their ability according to the laws in effect.
The board takes appropriate measures to exercise independent judgment when considering any transactions and agreements. If a director has a material interest, he excuses himself from the appropriate portions of the board and committee meetings so the directors can discuss the issue openly and candidly.
Material contracts
Other than material contracts described or listed elsewhere in this AIF and those contracts made in the ordinary course of business, we have not entered into any material contracts.
