Resource and Reserve Estimates

None of the Company’s properties have Mineral Reserves. Disclosure about the Company’s exploration properties in this Annual Report on Form 20-F uses the term “Mineral Resources”, “Measured Mineral Resources”, “Indicated Mineral Resources” and “Inferred Mineral Resources”, which are Canadian geological and mining terms as defined in accordance with National Instrument 43-101 (“NI 43-101”), standards of disclosure for mineral projects of the Canadian Securities Administrators, set out in the Canadian Institute of Mining (CIM)(“CIM”) Standards. These terms are not defined in the U.S. Securities and Exchange Commission (SEC)(“SEC”) Industry Guide 7,Description of Property by Issuers Engaged or to be engaged in Significant Mining Operations, and are normally not permitted to be used in reports and registration statements filed with the SEC. Accordingly, information contained in this Annual Report on Form 20-F containcontains descriptions of our mineral deposits that may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.

Cautionary Note to U.S. Readers concerning estimates of Measured Mineral Resources and Indicated Mineral Resources:This Annual Report on Form 20-F may use the terms “Mineral Resources,” “Measured Mineral Resource” and “Indicated Mineral Resource.” The Company advises U.S. investors that while such terms are recognized and permitted under Canadian regulations, the SEC does not recognize them. U.S. investors are cautioned not to assume that any part or all of the Mineral Resources in these categories will ever be converted into Mineral Reserves.

Cautionary Note to U.S. Readers concerning estimates of Inferred Mineral Resources:This Annual Report on Form 20-F may use the term “Inferred Mineral Resource.” The Company advises U.S. investors that while such a term is recognized and permitted under Canadian regulations, the SEC does not recognize it. “Inferred Mineral Resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules estimates of Inferred Mineral Resources may not form the basis of feasibility or other economic studies. U.S. investors are cautioned not to assume that any part of all of the Inferred Mineral Resources exist, or is economically or legally mineable.

RISK FACTORS

Investing in common stock of Quaterra Resources Inc. (the “Company” or Quaterra”) involvesThe Company’s securities should be considered a high degree of risk. Before deciding to purchase, hold or sell the Company’s common stock, youhighly speculative investment and investors should carefully consider all of the risks described below in addition to the cautionary statements and risks described elsewhere and the other information contained in this 20-F anddisclosed in the Company’s Canadian and U.S. regulatory filings prior to making an investment in the Company.

Resource exploration and development is a speculative business, characterized by a number of significant risks including, among other filings with securities regulatory authorities. The risks and uncertainties described belowthings, unprofitable efforts resulting not only from the failure to discover mineral deposits but also from finding mineral deposits, which, though present, are notinsufficient in quantity and/or quality to return a profit from production. Without limiting the foregoing, the following risk factors should be given special consideration when evaluating an investment in the Company’s only ones.securities. Additional risks and uncertainties not presentlycurrently known to Quaterrathe Company, or that Quaterrathe Company currently deems immaterial, may also impair the Company’s business operations. If any of these known or unknown risks or uncertainties actually occurs with material adverse effects on Quaterra, the Company’s business, financial condition, results of operations and/or liquidity could be seriously harmed, which could cause the Company’s actual results to vary materially from recent results or from the Company’s anticipated future results. In addition, the trading price of the Company’s common stock could decline due to any of these known or unknown risks or uncertainties, and you could lose all or part of your investment.

The Company may not have sufficient fundsrequire additional funding to complete further exploration programs.

The Company does not generate operating revenue and must finance exploration activity by other means, such as selling assets, raising funds through the continued sale of non-core assets, optioning certain property interests, such as the Yerington project copper assets to Freeport McMoran, the outright sale of properties, and finally, the issuance of debt and/or equity. The Company cannot provide any assurance that additional funding will be available for further exploration of the Company’s projects or to fulfill anticipated obligations under existing property agreements.

The consolidated audited financial statements have been prepared on a going concern basis, which assumes thatFailure to obtain necessary financing could result in delay or postponement of further exploration and development, and the Company will be able to realize its assets and discharge its liabilities in the normal course of business. The abilityproperty interests of the Company to continue as a going concernwith the possible dilution or loss of such interests. Further, financing will depend upon the success of exploration programs and meet its commitments as they become due, including completion of the exploration and development of its mineral properties, is dependent on the Company’s ability to obtain the necessary funding. Two sale transactions totaling US$9 million (Nieves and the sale of residual United States mineral properties to Freeport McMoRan Mineral Properties, Inc.) occurred in the fourth quarter 2014. With the closing of these transactions, management believes the Company has sufficient fundsgeneral market conditions for the next full year of operations.natural resources.

The Company has a history of losses and expectsanticipates to incur losses for the foreseeable future.

The Company has incurred losses during eachhad a history of losses. None of the reporting periods. Company’s properties are currently in production, and there is no certainty that the Company will succeed in placing any of its properties into production in the near future, if at all.

Quaterra expects to continue to incuranticipates continued losses unless andfor the foreseeable future until such time as one or more of the properties enterenters into commercial production and generategenerates sufficient revenues to fund the Company’s continuing operations. The Company had a positive working capital of $3,754,387 at December 31, 2014.

Future equity transactions could cause dilution of present and prospective shareholders.

Historically, the Company has financed operations through private placementsthe sale of common equity shares. Insecurities including convertible into equity securities or sale of its mineral interests. The Company may issue additional equity securities in order to finance future operations and development efforts, the Company may raise funds through the issue of common shares, the issuance of securities convertible into common shares through private placements or public offerings, or the sale of assets. The common shares in these financings often are sold at a discount to market prices, and the exercise price of the warrants sometimes is at or may be lower than market prices.efforts. The Company cannot predict the size and terms of future issuesissuances of common sharesequity securities or the issue of securities convertible into common shares or the effect, if any, that issues and sales of the Company’s common shares will have on the market price of its common shares.debt instruments. Any transaction involving the issue of common shares,equity securities or securities or convertible into common shares, could result in dilution, possibly substantial, to present and prospective holders of common shares, either at the time of the financing or subsequently when restrictions if any expire and the common shares are resold into the public markets.security holders. Similarly, the Company cannot predict the value of any asset sale nor its effect on the market price of its common shares.

The Company’s exploration programs may not result in a commercial mining operation.

Mineral exploration involves significant risk because few properties that are explored contain bodies of ore that would be commercially economic to develop into producing mines. Quaterra’s mineral properties are without a known body of commercial ore and the proposed programs are an exploratory search for ore. The Company cannot provide any assurance that current exploration programs will result in any commercial mining operation. If the exploration programs do not result in the discovery of commercial ore, the Company will be required to acquire additional properties and write-off all investments in existing properties.

The Company does not have Proven Mineral Reserves or Probable Mineral Reserves.

The Company has not established the presence of any Proven Mineral Reserves or Probable Mineral Reserves (as such terms are defined in National Instrument 43-101 of the Canadian Securities Administrators)NI 43-101) at any of Quaterra’s mineral properties. The Company cannot provide any assurance that future feasibility studies will establish Proven Mineral Reserves or Probable Mineral Reserves at Quaterra’s properties. The failure to establish Proven Mineral Reserves or Probable Mineral Reserves could restrict the Company’s ability to successfully implement its strategies for long-term growth.

Mineral resource estimates are subject to updates which may differ from prior estimates and adversely affect the value of the Company’s properties.

The estimating of mineralization is a subjective process and the accuracy of estimates is a function of the quantity and quality of available data, the accuracy of statistical computations, and the assumptions used and judgments made in interpreting engineering and geological information. There is significant uncertainty in these Mineral Resource estimates, and the actual deposits encountered and the economic viability of mining a deposit may differ significantly from our estimates. From time to time, Quaterra obtains updated resource estimates and technical reports related to the Company’s mineral properties.

The Company’s future business and financial condition are dependent upon resource prices.

Resource prices have fluctuated widely, particularly in recent years, and are affected by numerous factors beyond the Company’s control. These include international economic and political trends, inflation, currency exchange fluctuations, interest rates, global or regional consumption patterns, speculative activities and increased production due to new and improved extraction and production methods. These factors may negatively affect the marketability of any ore or minerals discovered at, and extracted from, Quaterra’s properties. If, because of a sustained decline in prices, financing werewas not available to meet cash operating costs, the feasibility of continuing operations would be evaluated and if warranted, would be discontinued.

3

The Company’s common share price has been and may continue to be subject to volatility.

U.S. and Canadian securities markets in recent years have experienced high levels of price and volume volatility, and the market price of securities of many companies have experienceexperienced wide fluctuationfluctuations in price which have not necessarily been related to the operating performance for underlying assets values or prospects of such companies. Factors unrelated to Quaterra’s financial performance or prospects include macroeconomic developments in North America and globally, and market perceptions of the attractiveness of particular industries. The Company’s share price, financial condition, and results of operations are all also likely to be significantly affected by short-term changes in copper, gold, and silver prices. Continual fluctuations in metal prices may occur. As a result of any of these factors, the market price of the Company’s shares at any given point in time may be subject to wide swings unrelated to any direct action by Quaterra’s operations.

Some of the Company’s directors and officers may have conflicts of interest due to their involvement with other natural resource companies.

Some the Company’s directors and officers are directors or officers of other natural resource or mining-related companies and these associations may give rise to conflicts of interest from time to time. As a result of these conflicts of interest, Quaterra may miss the opportunity to participate in certain transactions, which may have a material, adverse effect on the Company’s financial position.

- 9 -

The Company may experience difficulty attracting and retaining qualified management to grow Quaterra’s business.

The Company is dependent on the services of key executives including the Chief Executive Officer and other highly skilled and experienced executives and personnel focused on advancing corporate objectives as well as the identification of new opportunities for growth and funding. Due to the Company’s relatively small size, the loss of these persons or the Quaterra’s inability to attract and retain additional highly skilled employees required for activities may have a material adverse effect on the Company’s business and financial condition.

The Company may be limited in its ability to manage growth.

Should the Company be successful in its efforts to develop mineral properties or to raise capital for such development or for the development of other mining ventures, it may experience significant growth in operations. Any expansion of the Company’s business would place demands on management, operational capacity, and financial resources. The Company anticipates that it will need to recruit qualified personnel in all areas of operations. There can be no assurance that Quaterra will be effective in retaining current personnel or attracting and retaining additional qualified personnel, expanding operational capacity or otherwise managing growth. The failure to manage growth effectively could have a material adverse effect on the Company’s business, financial condition and results of operations.

Environmental and other regulatory requirements may limit the Company’s operations and increase expenses.

The Company’s operations are subject to environmental regulations promulgated by various Canadian, U.S., and Mexican government agencies. Claims and current and future operations will be governed by laws and regulations governing mineral concession acquisition, prospecting, development, mining, production, exports, taxes, labor standards, occupational health, waste disposal, toxic substances, land use, environmental protection, mine safety and other matters. Companies such as ours that engage in exploration activities often experience increased costs and delays in production and other schedules as a result of the need to comply with applicable laws, regulations and permits. Issuance of permits for Quaterra’s exploration activities is subject to the discretion of government authorities, and the Company may be unable to obtain or maintain such permits. Permits required for future exploration or development may not be obtainable on reasonable terms or on a timely basis. Existing and possible future laws, regulations and permits governing operations and activities of exploration companies, or more stringent implementation thereof, could have a material adverse impact and cause increases in capital expenditures or require abandonment or delays in exploration.

4

Operating hazards associated with mining may expose the Company to liability.

Mining operations generally involve a high degree of risk, including hazards such as fire, explosion, floods, structural collapses, industry accidents, unusual or unexpected geological formations. Operationsconditions, power outages, cave-ins, inclement weather, and mechanical equipment failure in which the Company has an interest are subject to all the hazardsCompany’s operations. These and risks normally incidental to exploration, development and production of minerals, any of which couldothers may result in work stoppages, damage to or destruction of mines and other producing facilities, damage to or loss of life and property, environmental damage and possible legal liability for any or all damage or loss. The Company currently does not maintain standard insurance policies on Quaterra’s properties. The Company may become subject to liability for cave-ins and other hazards for which cannot be fully insured or against which

Safety measures implemented by the Company may elect not be able to insure where premium costs are disproportionateobtain insurance to cover these risks at economically feasible premiums or at all. Insurance against certain environmental risks is not generally available to the Company’s perception ofCompany or to other companies within the relevant risks. For example, the Company is not currently covered by any form of political risk insurance or any form of environmental liability insurance. The payment of such insurance premiums and the incurring of such liabilities would reduce the funds available for exploration activities.mining industry.

The Company’s properties may be subject to uncertain title

The acquisition of title to resource properties or interest therein is a very detailed and time consuming process. Title to and the area of resource concessions may be disputed. The Company has investigated title to all of its mineral properties and, to the best of the Company’s knowledge, title to all of Quaterra’s properties are in good standing.

- 10 -

The properties may be subject to prior, and in some cases, not fully ascertainable unregistered agreements or transfers, and title may be affected by undetected defects. Title may be based upon interpretation of a country’s laws, which laws may be ambiguous, inconsistently applied and subject to reinterpretation or change.

Enforcement of judgments or bringing actions outside the United States against the Company and its directors and officers may be difficult.

Quaterra is organized under the law of and headquartered in British Columbia, Canada, and several of the Company’s directors and officers are not citizens or residents of the U.S. In addition, a substantial part of the Company’s assets are located outside the U.S. and Canada. As a result, it may be difficult or impossible for one to (a) enforce in courts outside the U.S. judgments against the Company and a majority of Quaterra’s directors and officers, obtained in U.S. courts based upon the civil liability provisions of U.S. federal securities laws or (b) bring in courts outside the U.S. an original action against the Company and its directors and officers to enforce liabilities based upon such U.S. securities laws.

On January 1, 2011, the Company entered into an option agreement with North Exploration LLC to acquire 41 mining claims in White Pine County, Nevada, known as Butte Valley property. The Company could earn a 100% interest in the claims by making staged payments totaling US$1 million. The Company had an option at any time to purchase the property for the difference between US$1 million and the sum of amounts previously paid or if the full amounts had been paid under the above the sum of US$1. The property was subject to 2.5% NSR upon commencement of commercial production of which 1% could be bought down for US$1 million. On October 2, 2012, Quaterra sold the Butte Valley porphyry copper prospect to Freeport-McMoRan Mineral Properties Inc. (FMMP). FMMP paid Quaterra US$2 million, with a contingent acquisition bonus of US$1 million possible in the future if FMMP acquired certain additional designated properties in the area. The bonus was subsequently paid on July 29, 2013. Quaterra also retained the right, if and when FMMP completed a positive feasibility study, to elect to have either a 30% working interest in the project or a 2% NSR royalty. Please see the note for October 3, 2014, below for subsequent developments.

On February 7, 2011, Quaterra completed a private placement of 3,293,407 units for gross proceeds of US$6.0M (C$5,994,000) received from Goldcorp of Vancouver, B.C., pursuant to the 2010 Goldcorp-Quaterra Investment Framework Agreement (“IFA”). Each unit consisted of one common share and one-half of one share purchase warrant with an exercise price of $2.27 per full warrant expiring February 7, 2013.

On April 27, 2011, Quaterra completed the purchase of the Yerington property from Arimetco, Inc. Assets purchased include 4.2 square miles of patented claims and fee mineral properties centered on the former Anaconda open pit copper mine including 8,600 acre feet per year of water rights. This property, together with 9.3 and 13.2 square miles of unpatented claims at Yerington and nearby MacArthur respectively, provides the Company with a significant land position in the center of an historic copper camp. Quaterra has paid the remaining cash acquisition cost and has released 250,000 common shares of the Company stock previously issued and under escrow.

On May 12, 2011, pursuant to its January 1, 2011 option, Quaterra announced its acquisition of the Butte Valley porphyry copper prospect, located in White Pine County, Nevada. The property consists of approximately 45 square miles of mineral rights obtained by optioning and staking a total of 1,483 unpatented U.S. lode claims. The property was subsequently sold to FMMP in 2014 as mentioned above.

On May 26, 2011, the Company entered into a mining lease with an option to purchase agreement with Majuba Mining Ltd. to earn an interest in certain unpatented mining claims in Lyon County, Nevada, for US$1.61 million.

The project is subject to 3% NSR upon commencing commercial production of which 1% can be bought for US$1,500,000. Subsequently, the work commitment has been extended to August 1, 2016.

On June 15, 2011, the Company entered into an option agreement with Nevada Alaska Mining Co., Inc. to acquire a 100% interest in certain mining claims in Esmeralda County, Nevada for US$1 million over ten years. A 2% NSR was required upon commercial production. The agreement was terminated on May 27, 2014, and the property returned to the lessee with no further obligation for Quaterra.

On July 4, 2011, Quaterra announced that it had finalized an option agreement with La Cuesta International, Inc. (LCI) to acquire a 100% interest in the Microondas prospect located in Zacatecas State, Mexico, about 17 kilometers south-southeast of Rio Grande. Quaterra had the right to earn a 100% interest in the property by making semi-annual lease/preproduction payments and paying a 1% Net Smelter Return royalty (“NSR”) payment that was capped at US$5 million. A portion of the property carried an uncapped 2% NSR royalty. Quaterra, at its option, could issue to LCI 20,000 common shares or its cash equivalent on or before June 12, 2012. The claims were dropped in April 2014 and the agreement terminated. The property was returned to the lessees with no further obligation for Quaterra.

On October 20, 2011, Quaterra added two properties to the Goldcorp IFA: El Calvo gold, located in the central Mexican state of San Luis Potosi, and Microondas gold-silver, located in Zacatecas State, Mexico.

GENERAL DEVELOPMENT OF THE BUSINESS

The Yerington Projects, Nevada

Quaterra’s Yerington Projects – located in the historic Yerington Copper District, about 70 miles southeast of Reno, Nevada, consist of the Yerington pit oxide-sulfide deposit previously mined by the Anaconda Mining Company; the MacArthur oxide and sulfide deposits; the Bear porphyry copper deposit; and a number of untested exploration targets. Quaterra’s 51-square-mile land package is situated in a mining-friendly jurisdiction with a history of copper production and good infrastructure. It also owns valuable water rights in the district.

The location of the Company’s Yerington project is provided on the following maps.

a.Yerington Deposit – Nevada, USA

The Yerington deposit refers to the former Anaconda mine site, a large partially mined porphyry copper system that includes the Yerington mine and a portion of the Bear copper deposits. The Anaconda Company conducted open pit mining from 1953 to 1978, producing 1.75 billion pounds of copper from first oxide, and later, sulfide ores. The Atlantic Richfield Company bought the Anaconda Company in 1977 and terminated work on the site shortly thereafter.

Acquisition and Staking of Claims

The Yerington Pit property totals approximately 11 square miles. The project mineral rights consist of 2,768 acres of fee mineral properties and patented mining claims as well as 201 unpatented lode and placer claims totaling 4,153 acres on lands administered by the BLM. The total reflects the transfer of 345 claims of the MacArthur Deposit from Quaterra Alaska Inc. to SPS in August 2015.

On May 1, 2007, SPS received the bankruptcy court approval for the acquisition of certain assets of Arimetco Inc. (“Arimetco”) in the Yerington Mining District, subject to completion of due diligence. The purchase price comprised $500,000 cash, 250,000 of the Company’s common shares and a 2% net smelter return royalty capped at $7.5 million dollars on production from any claims owned by the Company in the Yerington Pit and MacArthur Deposit mine areas.

SPS purchased the Yerington Mine properties along with the appurtenant ground water rights from the Arimetco bankruptcy court in April 2011. This included private land, patented claims, and 23 unpatented mining claims related to the Yerington Mine. The acquisition followed three years of due-diligence studies and negotiations with state and federal agencies and the receipt of Bona Fide Prospective Purchaser (“BFPP”) letters from the U.S. Environmental Protection Agency (“EPA”), the Nevada Division of Environmental Protection (“NDEP”) and the US Bureau of Land Management (“BLM”) to protect SPS from liability emanating from activities of the former mine owners and operations.

11

SPS purchased the Anaconda mine and MacArthur Deposit mine properties along with the appurtenant ground water rights in 2011. SPS owns approximately 8,600 acre-feet/yr of primary ground water rights that have senior priority standing. These water rights are specifically permitted for mining and milling and have significant value. Primary ground water in Mason Valley, Nevada has sold for $3,000 per ac-ft.

Private properties related to the Arimetco acquisition are located in Township 13 North, Range 25 East in Sections 4, 5, 8, 9, 16, 17, and 21, and patented claims are located within Township 13 North, Range 25 East in Sections 16, 17, 19-21, 31-33 and in Township 13 North, Range 24 East in Sections 22-27 and 36. An additional 434 unpatented claims in Sections 1, 2, 11-13, 23-26, 35, and 36 Township 13 North, Range 24 East and in Sections 4-9, 16-21, and 30 Township 13 North, Range 25 East, and in Sections 1, 2 Township 12 North, Range 24 East Mount Diablo Base & Meridian were staked prior to or subsequent to the acquisition by SPS.

Expenditures to Date

Acquisition and exploration costs incurred by the Company for the Yerington Pit to December 31, 2017 were $13.27 million (2016 - $10.65 million) of which $3.20 million was funded by Freeport Nevada.

Location, Access and Infrastructure

The Yerington Mine property is located near the geographic center of Lyon County, Nevada, USA, along the eastern flank of the Singatse Range. The property centers on the historical Anaconda open pit mine, flanked on the west by Weed Heights, Nevada (a small private community; the original company town of Anaconda) and on the east by the town of Yerington, Nevada. The property is easily accessed from Yerington by a network of paved roads that were used as principal transportation and access routes during the former operating period of the mine. SPS controls approximately 8,600 acre feet of groundwater rights and the Yerington Pit contains an estimated 40,000 acre feet of water. Power is currently on-site and a new substation is being constructed a quarter mile to the South. Nevada Energy operates a 226 Megawatt natural gas fueled power plant within ten miles of the site. Power for future mining operations is expected to be readily available. Topographic coverage is on US Geological Survey “Yerington” and “Mason Butte” 7.5’ topographic quadrangles. The nearest major city is Reno, Nevada, approximately 80 miles to the northwest.

History

Recorded production in the Yerington mining district dates back to 1883 (Moore, 1969) as prospectors were attracted to and investigated colorful oxidized copper staining throughout the Singatse Range. Knopf (1914) reported that oxidized copper cropped out at the historic Nevada-Empire mine located above the south center of the present-day Yerington open pit. Knopf does not show or reference other mines or prospects that are underlain by the Yerington open pit footprint, as gravel and alluvial cover obscure bedrock over an approximate 0.75 -mile radius around the Nevada-Empire Mine.

During the 1940s, Anaconda, at that time one of world’s major copper producers, outlined a 60 million-ton resource over the Yerington Pit. During the early 1950s, the US government, citing the need for domestic copper production, offered “start-up” subsidies to Anaconda to open a copper mine in the Yerington district. Anaconda sank two approximately 400-foot-deep shafts in the present-day open pit and drove cross cuts to obtain bulk samples of oxidized rock for metallurgical study. Anaconda began operating the Yerington Pit in 1952 and mined continuously through 1978, producing approximately 1.744 billion pounds of copper from an ore body that contained 162 million tons averaging 0.54% Cu. Approximately 104 million tons of this total were oxidized copper ore that was “vat-leached” with sulfuric acid in 13,000-ton cement vats on a seven day leach cycle. Sulfide ores were concentrated on site in a facility that was dismantled and sold following termination of mining in 1979.

12

In 1976, all assets of Anaconda, including the Yerington Pit, were purchased by the Atlantic Richfield Company (ARCO) which in 1979 shut down dewatering pumps in the pit and closed the Yerington Pit due to low copper prices. In 1982, ARCO sold the entire Yerington Pit complex and Weed Heights town site to Mr. Don Tibbals of Yerington, Nevada, who scrapped the plant and equipment. At closure, before dewatering pumps were shut off, the Yerington Pit plan hosted a pre-stripped, non NI 43-101 compliant historic “reserve” of 98 million tons averaging 0.36% Cu containing approximately 696 million pounds of copper (K. L. Howard, Jr., Anaconda Internal Memo, 1979) within the ultimate pit design. The estimate was prepared from a geologic section calculation using a 0.2 %TCu cut-off grade. A qualified person has not done sufficient work to classify these historic estimates as a current mineral resource and Quaterra does not treat them as such. Although the 1979 estimate contained no classification for measured, indicated, or inferred resources as defined by NI 43-101, the total estimate compares favorably to a Tetra Tech NI 43-101 compliant independent resource estimate completed in February 2012. An additional 22.8 million tons of material containing 136.8 million pounds copper was identified adjacent to the pit in this historic estimate. The K. L. Howard, Jr., Anaconda Internal Memo (1979) addressing this material is considered reliable because it cites mine reconciliation calculations and geologic projections from drill holes using a 0.2% Cu grade cutoff in an internal Anaconda memo by T. Leigh to W.C. Norem (1979).

In 1989, Arimetco purchased the mine property from Tibbals, commissioned a 50,000-pound-per-day solvent extraction/electrowinning plant, and began heap leaching “sub-grade” dump rock stripped from the Yerington Pit by Anaconda. Arimetco also added an unknown tonnage of “vat leach tailings” (minus 3/8 inch oxidized tailings leached during Anaconda’s operation) to some heap leach pads (“HLP's”) as well as trucking oxidized ore from the MacArthur Deposit located approximately five miles north of the Yerington Pit site. Arimetco produced some 95 million pounds of copper from 1989 to 1999 before declaring bankruptcy due to low copper prices and abandoning the property.

Soil and groundwater contamination, alleged to stem from the former mining operations at Yerington, have been identified on the property. As a result, a portion of the property acquired by SPS in 2011 is now under the jurisdiction of the EPA. Liability for the contamination on site is the responsibility of a third party which is actively engaged in remedial investigation and remediation activities under the supervision of the U.S. Environmental Protection Agency (“EPA”).

In order to establish SPS’s position and rights, the acquisition by SPS of the Arimetco properties required a series of rigorous environmental, legal, and technical due diligence studies. The Chambers Group Inc. and Golder Associates Inc. completed a Phase 1 Environmental Site Assessment Report to allow SPS to establish liability protection as a Bona Fide Prospective Purchaser (“BFPP”). Prior to closing on the property, SPS received letters from the NDEP, BLM and the USEPA indicating the post-closing requirements then applicable to the Yerington Pit site for SPS to maintain its defense to liability as a BFPP regarding the activities of the former mine owners and operators.

In September 2012, SPS reached a voluntary agreement with the EPA to participate in upgrading the system that manages fluids from the historic mining operation at the Yerington mine site. In exchange for SPS’s participation in this work, the Company obtained a site-wide ‘Covenant Not to Sue’ for the contamination left at the site by former owners and operators of the historic mine operations.

The agreement provides for immediate environmental improvements to the site and allows SPS to continue exploration at the site while working cooperatively with the EPA, Nevada Division of Environmental Protection (“NDEP”) and the community. The Agreement’s ‘Covenant Not to Sue’ strengthens SPS’s ‘Bona Fide Prospective Purchaser Defense’ against liability resulting from the contamination at the site prior to SPS’s purchase.

The first phase of the fluid management project was completed in Q4 of 2012. The Company co-funded the repairs to the on-site fluid management system (“FMS”) by the EPA as well as the relining of one of the system ponds. During Phase 2 of the project, the Company completed a study of the FMS to determine what additional repairs or other modifications are necessary to ensure that the system is capable of handling the fluids from the former mine operations for a period of five years. The Study was completed by the Company’s contractor in June 2013. EPA decided not to implement the five-year capacity alternative recommended in the Study. Rather, EPA decided to build new ponds to address the FMS capacity issues.

13

The Company decided not to fund construction of the additional ponds. Rather, the Company agreed to provide property at the site to construct the new ponds.

In September 2014, SPS submitted to EPA a Final Report that documented the work SPS performed under the EPA Agreement. On January 7, 2015, the EPA issued a Notice of Completion to SPS confirming that the obligations of the Work to Be Performed and the Payment of Response Costs sections of the Settlement Agreement had been met. With the issuance of the Notice of Completion, SPS believes it does not have further obligations under the Agreement, except for those as a landowner and as a Bona Fide Prospective Purchaser.

In December 2015, the EPA sent a request to the Nevada Governor seeking the State’s support for listing the Anaconda-Yerington Mine Site on the EPA National Priorities List (“NPL”). EPA has been considering an NPL listing as a mechanism to provide federal funds for remediation of contamination of the site left by former owners Arimetco Inc. This portion of the Site is referred to as Operable Unit 8 (OU8) and is an unfunded liability due to Arimetco’s bankruptcy. The Governor responded to the EPA noting that the State will not object to the initiation of the listing process.

On September 9, 2016, via publication in the Federal Register, the EPA proposed 10 new sites for NPL listing. The Anaconda Copper Mine in Yerington Nevada was one of those ten sites proposed for listing. EPA proposed to list the entire Site despite the fact that there is a responsible party, Atlantic Richfield Company, which has and continues to perform its obligations at the Site. SPS has a ‘Covenant Not to Sue’ with the EPA, and believes it qualifies for the ‘Bona Fide Prospective Purchaser Defense’ to CERCLA liability. The existing contamination at the Site, other than that for which EPA seeks the listing is the responsibility of the Atlantic Richfield Company that has been working with EPA to study the contamination, design remedial activities and implement remediation at the Site. SPS’s work program at the Bear deposit was not affected by the EPA proposed listing of the Site. Also, SPS does not believe that an NPL listing precludes advancing mineral exploration and development at the Site. Only the Yerington mine site falls within the area of the proposed NPL listing; the Company’s other targets in the district occur outside the area of the proposed listing.

In July 2017, NDEP made a formal request to EPA to defer the listing of the Site on the NPL. Since the original request, NDEP, EPA and Atlantic Richfield have worked toward a deferral of the listing process noted above. In support of a deferral action NDEP and EPA are negotiating the terms of a Deferral Agreement, NDEP and Atlantic Richfield are negotiating the terms of an Interim Administrative Order on Consent, and Atlantic Richfield and NDEP are negotiating a Statement of Work for a Site-Wide Remedial Investigation and Feasibility Study. These documents have not yet been provided in final form. As recently as January 2018, NDEP corresponded with EPA to address concerns noted by EPA as to the Interim Administrative Order on Consent. Neither Quaterra nor SPS have direct involvement in the negotiation of these documents but support the deferral process.

The Company is negotiating an agreement with Atlantic Richfield that will provide the framework for how the two entities will work together on the Site allowing Atlantic Richfield to complete its remedial activities and the Company to move forward with its development of the Site.

Geology and Mineralization

The Yerington Pit property includes both the Yerington deposit (the “Yerington Deposit”) and a portion of the Bear Deposit which represent two of three known porphyry copper deposits in the Yerington copper district. The porphyry systems are hosted in middle Jurassic intrusive rocks of the Yerington Batholith. Unless noted otherwise, the following discussions refer to the Yerington Deposit.

Mineralized porphyry dikes associated with three phases of intrusive activity related to the Yerington Batholith form an elongate body of mineralization that extends 6,600 feet along a strike of N118°E. The mineralization has an average width of 2,000 feet and has been defined by drilling to an average depth of 250 feet below the Yerington Pit bottom at the 3,800-ft elevation. Because of the economic constraints of low copper prices at the time, many of the 792 historic Anaconda drill holes used in the SPS study were stopped in mineralization and very few were drilled below the 3,400-ft level where the porphyry system remained largely unexplored.

14

Only four historic holes have actually explored the deep vertical projection of copper mineralization in the pit. Three of the holes were drilled along a single N-S oriented section through the center of the pit. According to M. T. Einaudi in an internal 1970 Anaconda report, the deep drilling program defined a series of nested, concave upward, grade shells that are elongated down the N 70° dip of the dikes with the 0.2% Cu zone extending to approximately the 2,600-ft level; an overall dip distance of 2,200 feet. Although the program encountered an increasing ratio of pyrite to chalcopyrite, there was no indication of a “barren core”, the porphyry dikes showed a “remarkable continuity” down dip and molybdenum mineralization became more abundant with increasing depth.

Secondary oxide copper formed much of the upper Yerington Deposit. Chrysocolla was the dominant copper oxide mineral, occurring as fracture coatings and fillings to a depth of approximately 400 feet below the surface. Below the 4,100-ft level, chalcopyrite is the dominant copper sulfide mineral with minor bornite primarily hosted in A-type quartz veins in the older porphyry dikes. The un-mined mineralized material below the current pit bottom is primarily of chalcopyrite mineralization.

Exploration and Drilling Results

Exploration work on the Yerington Pit project commenced with a technical review of all available historical information relating to mineralization in and around the Yerington Pit. A huge inventory of Anaconda data was available at the Anaconda Collection – American Heritage Center, University of Wyoming at Laramie. Approximately 10,000 pages of drill hole records from the library were scanned. The records included drill hole lithology, assays, and/or survey coordinates for almost 800 drill holes. Although some holes contained only lithologic or assay summary information, 892 holes contained adequate detailed assay, hole location and orientation information to be used in a resource estimation. Core from historical drilling left on site by Anaconda was photographed, described and selected intervals from 45 Anaconda core holes were shipped to Skyline Labs for re-assay.

Information obtained from the review of historical information was used to guide a two-pronged program of drilling during the last half of 2011. A total of 21,887 feet were drilled in 42 holes. The core holes and four RC holes were drilled to twin Anaconda core holes, while the remaining RC holes were targeted for expansion of mineralization laterally and below historic drill intercepts along the perimeter of the Yerington Pit to support a NI 43-101 compliant resource estimate and technical report.

The data review and drilling results of the 2011 program clearly indicated that mineralization at Yerington is open to depth and along strike. Many of the historic holes in the pit were stopped in mineralization. Drill hole intercepts along the western edge of the pit are some of the best in the SPS database. Twin hole SP-04, drilled by SPS at the northwest end of the pit, intercepted 524.5 feet averaging 0.35%TCu starting at a depth of 228 feet including 88 feet of 0.69%TCu at a depth of 265 feet. Exploration hole SP-36, located along south central margin of the pit intercepted 95 feet averaging 0.28% TCu at a depth of 230 feet. Details of the 2011 drilling program are in the NI 43-101 technical report for the Yerington Pit project completed by Tetra Tech, Inc. of Golden, Colorado (“Tetra Tech”) in February 2012 (the “Yerington Technical Report”).

A drilling program to sample residuals (historic dumps and tailings) at the Yerington Pit site was completed in September 2012. A total of 9,585 feet of sonic drilling in 95 holes have provided material for the characterization of the vat leach tails, heap leach pads, and the W-3 sub-grade waste dump. Selected samples were sent to Metcon Labs in Tucson, Arizona for metallurgical testing. These residuals have been historically estimated to total 124 million tons of mineralized material. The residuals are referenced in the MacArthur Deposit PEA and the Yerington Technical Report, as “mineralized material” and therefore are neither an NI 43-101 compliant resource nor a historical resource. Additional details regarding the residuals are described in the Yerington Technical Report. The residuals are not included in the resource estimate at the Yerington Pit site or in the MacArthur Deposit PEA or resource estimate at the MacArthur Deposit site.

Sampling, Analysis and Security of Samples

Tetra Tech’s review of sample preparation, handling, analyses, and security procedures for the Yerington drilling and sampling program has determined that the Company’s current practices meet NI 43-101 and CIM defined requirements.

Samples taken during the period from 1952 to 1979, when Anaconda operated the Yerington Pit, including samples used for the determination of mine head grades, lithology, densities, and metallurgical performance were determined by Tetra Tech to be representative of the deposit. While no details are available regarding Anaconda’s exact assaying protocol and quality control during the period the Yerington Pit copper mine was operating, public records of profit and cost confirmed that the techniques and procedures implemented conformed to industry standards for that era.

SPS explored the Yerington Pit copper property with both RC and diamond core drilling methods. The drilling program was supervised in the field by the project geologist for monitoring recovery, proper sample handling and accuracy in labeling. Approximately 4,300 samples were collected during the 2011 program and shipped for sample analyses. The samples were analyzed for total copper (TCu), gold, and a 47-element trace element package. Samples representing oxide mineralization and acid soluble sulfide copper were also analyzed for acid soluble copper and for ferric sulfate soluble copper. Rock quality designations (“RQD”) and magnetic susceptibility measurements were taken on all core which was photographed following geologic logging.

The RC samples are collected in a conventional manner via a cyclone and standard wet splitter, placed in cloth bags that are pre-marked by SPS personnel at five-foot intervals and include a numbered tag inserted into a plastic bag bearing the hole number and footage interval. Collected samples, weighing approximately 15 to 20 pounds each, are wire tied and then loaded onto a ten-foot trailer with wood bed allowing initial draining and drying. Each day SPS personnel or the drillers at the end of their shift, haul the samples to SPS’s secure sample preparation warehouse in Yerington, Nevada where the samples are dried, loaded on plastic lined pallets, weighed, and trucked by Skyline Assayers and Laboratories (“Skyline”) personnel to Skyline’s sample preparation facility in Battle Mountain, Nevada. A chain of custody form accompanies all shipments from Yerington to Battle Mountain. Once Skyline preps each sample in its Battle Mountain facility, approximately 50-gram sample pulps are air-freighted to Skyline’s analytical laboratory in Tucson, Arizona for analyses and assay.

Samples from the core drilling program are handled in a similar manner. Core samples with a diameter of approximately 2.75 -inches (HQ) are placed in wax-impregnated, ten-foot capacity cardboard boxes and delivered to SPS’s secure sample warehouse in Yerington, Nevada by the drill crew following each 12-hour shift. The core is logged by a SPS geologist who marks appropriate sample intervals (one to nominal five feet) with colored flagging tape. Lines are marked along the length of core with red wax crayons to indicate where the core piece should be sawed. Each core box, bearing a label tag showing drill hole number, box number, and box footage interval, is then photographed. RQD, magnetic susceptibility, and recovery measurements are taken. Core is then loaded on a pallet, shrink wrapped, and secured with wire bands for trucking by Skyline personnel to Skyline’s sample preparation facility in Battle Mountain, Nevada. The core is sawed in half by Skyline personnel, one half designated for sample preparation/assay, the second half placed in its core box for return to SPS. Chain of custody procedures for core shipments picked up by Skyline at the SPS core shed follow the format for RC samples.

Drilling samples from the Yerington Pit project were analyzed by Skyline in Tucson, Arizona, which is accredited by the American Association for Laboratory Accreditation (A2LA - certificate no. 2953.01) and by ISO17025-compliant ALS Minerals Laboratories in Sparks, Nevada. SPS implements a quality assurance and quality control assay protocol whereby either one blank or one standard is inserted with every ten samples into the assay stream. Rejects from the previously analyzed samples are sent to ALS Minerals in Reno, Nevada for check assays.

Mineral Resources

Tetra Tech completed a NI 43-101 compliant independent resource estimate and technical report update for the mineralization in and around the historic Yerington Pit titled“NI 43-101 Technical Report Mineral Resource UpdateYerington Copper Project Lyon County, Nevada” and dated January 3, 2014 (effective November 20, 2013), which supersedes its previous report completed in February 2012 (the “Updated Yerington Technical Report”). The Updated Yerington Technical Report is based upon an additional 232 historic Anaconda holes unavailable when the previous report was completed. The current resource now includes over 800 boreholes.

16

These additional holes are well distributed throughout the deposit and provided infill and extensional information to the previously used data, allowing upgrades in classification, improved grade estimate and a new resource definition.

The increases to the February 2012 resource are as follows. Using a 0.12% TCu copper cutoff, measured and indicated oxide and chalcocite resources increased 28% in tons, 9% in grade, and 37% in pounds of contained copper while the inferred resource increased 5% in tons, 14% in grade, and 21% in contained copper. Using a 0.15% TCu copper cutoff, the primary measured and indicated resources increased 12% in tons, 12% in grade, and 25% in contained copper while the inferred resource increased 4% in tons, 11% in grade, and 13% in contained copper.

Using a cutoff grade of 0.12%, the Yerington Pit’s measured and indicated acid-soluble oxide/chalcocite mineralization includes a measured and indicated resource of 23.5 million tons averaging 0.25% TCu (118 million pounds of copper) and an inferred resource of 25.9 million tons of 0.23% TCu (118 million pounds of copper). Using a cutoff of 0.15% TCu, the measured and indicated primary copper resource contains 105 million tons averaging 0.30% TCu (633 million pounds of copper) and an inferred primary copper resource of 128 million tons of 0.23% TCu (600 million pounds of copper).

Cutoff grades of 0.12% and 0.15% for the oxide/chalcocite and sulfide mineralization, respectively, were used in the Updated Yerington Technical Report based on benchmarking of the Yerington Deposit to similar deposits using open pit mining. The cutoff values are representative of grades and recoveries used in calculating the mineral resources for the preliminary economic assessment for the Company’s adjacent MacArthur Copper Project, which is described in a NI 43-101 technical report filed in January of 2014 using an effective date for the resource calculation of May 2012. The MacArthur study indicates that using the cutoff grades in the report, the project has reasonable prospects for economic extraction of mineralization. The Yerington and MacArthur deposits are adjacent, geologically similar and have similar grade continuity. Open pit mining methods are proposed for both deposits. They will use similar metallurgical processes. The cutoff grades are based on similar costs, metal prices and mining/metallurgic parameters. The benchmark values applied to the Yerington Project from the MacArthur project are:

The following table summarizes the resource estimates contained in the Updated Yerington Technical Report, including changes from the previous report prepared in February of 2012:

The results of the 2013 NI 43-101 compliant resource estimate compare favorably to the estimates of copper remaining in and around the Yerington Pit after the mine shut down (K.L. Howard, Jr., Anaconda Internal Memo, 1979). The 1979 estimate contained no classification for measured, indicated, or inferred, so direct comparison can only be made when considering all classes of the current estimate, but was reported at 121 million tons with an average grade of 0.34% TCu.

The 1979 estimate cited approximately 84% of the total contained copper (696 million pounds of copper in 97.8 million tons with an average grade of 0.356% Cu) as being within the original Anaconda pit design, suggesting that a significant portion of the Yerington Pit resource may be mined without a pushback or major changes to the upper walls of the Anaconda pit.

The current Tetra Tech resource estimate is based upon SPS’s 2011 drilling as well as 792 historic drill holes taken from approximately 10,000 scanned pages of assay and/or geologic data which were reviewed and digitally recorded by SPS personnel and from 57 Anaconda cross sections in use at the time of mine closure. The digital data entry was validated by Tetra Tech against historic sections and was considered to be compliant, based upon results of 18 twin holes and 5,446 feet of core from Anaconda holes which were assayed by SPS. The twinned drill intercepts statistically confirmed that the new compliant data support use of the historical data, as did the new core assays which were well within the expected norms for corroborating the old with new data.

The Tetra Tech resource estimate is included with a description of the project history, geology, mineralization, sampling procedures, and laboratory Quality Assurance/Quality Control procedures. The Updated Yerington Technical Report is available at www.sedar.com.

2017 Drill Program

In March 2017, Quaterra and SPS commenced drilling at Yerington with the area in and around the historic Yerington pit as the primary focus. The drill program was funded by option payments by Freeport Nevada.

Hole YM-041A-17, drilled at - 55 degrees, intersected 561.7 feet averaging 0.20% copper, including several narrower intercepts with plus 0.30% copper. Hole YM-042-17, also drilled at - 55 degrees, collared in the pit about 1,000 feet further west, intersected a similar but lower grade interval averaging 0.12% copper. Hole YM-043-17, drilled at - 55 degrees, intersected 1,269.5 feet averaging 0.15% copper. Hole YM-045-17, also drilled at - 55 degrees, collared in the pit about 900 feet further east, intersected several thinner intervals with grades ranging to 0.55% copper, including a shallow oxide zone Hole YM-044-17, drilled on the northwest rim of the Yerington pit at - 50 degrees, intersected several narrow zones of mineralization averaging less than 0.2% copper.

*Drill intercepts are based on actual core lengths and may not reflect the true width of mineralization

Drilling extended sulfide mineralization from 600 to 800 feet below the currently defined resource identified at the Yerington pit across a strike length of 4,400 feet. The absence of higher-grade mineralization in widely spaced holes decreases the likelihood that better grades over appreciable widths exist at greater depth below the pit.

Mineralization, primarily chalcopyrite, is hosted in a quartz monzonite-quartz monzonite porphyry complex and occurs as sheeted veins and vein swarms that are steeply dipping and strike northwesterly parallel to the long axis of the pit. Copper grades are directly related to vein intensity and spacing, which vary markedly over short distances.

Quality assurance and control

Drilling included both reverse circulation (RC) and core, contracted to Layne Christensen Company, Chandler, Arizona, which provided both drill rigs. Core samples were either sawed or split by SPS personnel in Yerington, Nevada, and shipped to Bureau Veritas Minerals NA – Inspectorate America Corporation, an ISO certified assaying/geochemistry facility, in Reno, Nevada, for sample preparation. Gold analyses are assayed in Bureau Veritas’ lab in Reno using their “FA430” procedure (fire assay with atomic absorption finish) with a 5 ppb Au detection limit. Prepared pulps are shipped to Bureau Veritas’ lab in Vancouver, B.C., Canada, for analysis using their “MA 300” procedure for 35 element ICP-ES analysis. Commercially prepared standards and blanks are inserted by SPS at 50-foot intervals to insure precision of results as a quality control measure. SPS has a chain of custody program to ensure sample security during all stages of sample collection, cutting, shipping, and storage.

20

SPS also engaged a reverse circulation (RC) drill rig in the program. RC samples were shipped to the Bureau Veritas Minerals NA facility in Reno, Nevada, for sample preparation and analyses following the same procedure and protocol, including inserted blanks and standards, as that of the core samples described above.

Future Work Plans

Quaterra believes the Yerington Pit project has potential for additional copper resources. Historic and current drilling data indicate that horizontal and vertical limits to the mineralization at the Yerington Pit have not yet been found. Additional exploration and in-fill drilling is planned to both expand and upgrade the current NI 43-101 compliant copper resources of the project.

Acquisition and Staking of Mineral Claims

The MacArthur propertyDeposit consists of 897 unpatented lode claims totaling approximately 18,533 acres on lands administered by the US Bureau of Land Management (“BLM”). The total reflects the addition of 345 claims transferred from Quaterra’s wholly owned subsidiary, Singatse Peak Services LLC (SPS) to Quaterra Alaska’s MacArthur project in July 2012.BLM. A significant number of the claims arewere held by means of a mineral lease with an option to purchase, executed with North Exploration LLC (“North”) on August 27, 2005, and subsequently amended. The agreement gives Quaterra the right to purchase the claims from North Exploration LLC (“North”) by making 3 annual payments of $524,000 (option balance) plus interest at the rate of 6% per annum by January 15, 2013. The second of these three annual paymentsoption was paid January 11, 2012. The third payment was renegotiated on December 14, 2012 to defray the final option balance by making a $100,000 payment plus $31,440 in interest prior to January 15, 2013 to extend the lease and option to January 15, 2014. The final payment was subsequently spilt and delayed to July 1, 2014 for US$212,000 with the payment of $36,940 interest to be paid on March 31, 2014exercised and the reaming US$212,000 plus interest by January 15, 2015. (The final payment of $212,000 plus interest to North was made on February 10, 2015)2015. Quaterra’s purchase is subject to a two percent Net Smelter Return (NSR)2% NSR royalty, with a royalty buy down option1% of which may be purchased for $1,000,000, to purchase one percent of the NSR, leaving a perpetual one percent1% NSR.

Location, Access and Infrastructure

The MacArthur Copper ProjectDeposit is located near the geographic center of Lyon County, Nevada, USA, along the northeastern flank of the Singatse Range approximately seven miles northwest of the town of Yerington, Nevada. The project is accessible from Yerington by approximately five miles of paved roads and two miles of maintained gravel road. A 100-foot wide gravel haul road that accessed the MacArthur open pit copper mine during the 1990s leads 53.5 miles south to the Yerington Mine.Mine Site. Beyond the MacArthur Deposit pit area are several existing historic two-track dirt roads that provide access throughout the property. Topographic coverage is on US Geological Survey “Mason Butte” and “Lincoln Flat” 7.5’ topographic quadrangles. The nearest major city is Reno, Nevada approximately 7580 miles to the northwest.

History

ThePrior to 1989, the MacArthur project has been the subject of explorationDeposit was explored and drillingdrilled by several operators who have contributed to the current database of more than 740 holes totaling approximately 282,000 feet. During the late 1940s, Consolidated Copper Mines attracted the interest of the US Bureau of Mines to conduct 7,680 feet of trenching in 1948 and followed up with the completion of eight core holes for 3,414 feet in 1950.early 1970s, The Anaconda Company (“Anaconda”) began investigations at MacArthur including 33 shallow drill holes during 1955, 1956, and 1957. In 1963, Bear Creek Mining Company (“Bear Creek”) optioned claims and drilled at least fourteen air rotary holes, the deepest to 663 feet. At least four holes for 1,237 feet were drilled to satisfy claim staking location work. During 1967 to 1968, The Superior Oil Company optioned the claims formerly held by Bear Creek and drilled eleven holes as rotary pre-collar, core finish, for 13,116 feet testing the concept that a deep primary sulfide-bearing porphyry copper ore shell might underlie the MacArthur oxide mineralization heretofore tested no deeper than 663 feet. During the early 1970s, Anaconda conducted an extensive trenching and rotary drilling program consisting of more than 280 rotary holes totaling approximately 56,000 feet over and adjacent to the present day MacArthur Deposit pit.

Metech Pty. Ltd., of Perth, Australia was commissioned to prepare an ore reserve and mining planning study ofArimetco purchased the MacArthur depositproperty in 1989 The Metech study initiated the purchase of the Anaconda Yerington district properties by Arimetco International (“Arimetco”). Arimetcoand mined a total of six million tons at an estimated grade of 0.36 % total copper using open pit methods from the MacArthur depositDeposit in the period of 1995 to 1998. Due to financial difficulties resulting primarily from the low price of copper, Arimetco sought protection under Chapter 11 of the U. S.U.S. bankruptcy Code in January 1997 and suspended all operations in 2000. After Arimetco’s departure, the mining claims over the deposit were allowed to expire. No consistent, large-scale mining has occurred on the site.lapse.

Quaterra acquired the MacArthur propertyDeposit in August 2005. The acquisition was motivated by Quaterra’s belief in the potential of the property to host aan oxide copper deposit capable of sustaining a large run-of-mine heap leach operation using a solution extraction/electrowinning (SXEW) process for low cost production. The Company initiated exploration drilling in April 2007 and by November 2011, completed a total of 204,700 feet of drilling in 401 holes on the property. The drilling program has defined a widespread blanket of acid soluble copper oxide and chalcocite mineralization above primary copper mineralization that is believed to be the fringesfringe or top of a major copper porphyry system.

Geology

The MacArthur copper depositDeposit forms part of the Yerington mining district which includes at least three large, porphyry copper deposits (Yerington, Ann Mason, Bear), as well as two large iron-oxide copper gold (IOCG) deposits (Pumpkin Hollow, and Minnesota). Mineralization ranges from disseminated porphyry copper occurrences to skarn, limestone replacement, and vein type deposits.

The Yerington area is underlain by early Mesozoic volcanic and sedimentary rocks now exposed along uplands in the Singatse Range in the west and the Wassuk Range to the east. These Mesozoic rocks were intruded by two Middle Jurassic batholiths, an older granodiorite (Yerington Batholith) and younger quartz monzonite (Bear Quartz Monzonite) that comprise the majority of outcropping rocks in the district. The batholiths were themselves intruded by another Middle Jurassic quartz monzonite event moderately to steeply north dipping quartz-biotite-hornblende porphyry dike swarms, associated with copper mineralization, striking north-northwesterly across the entire mining district. The Mesozoic section is overlain by Early to Middle Tertiary volcanics deposited ash flow tuffs prior to the advent of normal faulting associated with Late Tertiary basin-and-range extension that displaced and tilted all of the above-mentioned rocks. These faults dip east and are curved, concave upward, so that the dip of the fault flattens eastward. Net displacements are in an east-west direction. The geologic section is completed by post-faulting conglomerates and alluvium.

At the MacArthur Deposit, the older granodiorite underlies most of the northern and western parts of the Company’s claim block. Along the east part of the claim, block quartz monzonite is dominant and underlies the MacArthur Deposit pit. In bench walls at the MacArthur Pit,Deposit pit, the quartz monzonite hosts conspicuous light brown limonite alteration banding (averaging 4 to 6 per foot) sub-parallel to the steeply north dipping, west-northwest trending quartz porphyry dikes. Along the eastern portions of the property, including the eastern third of the MacArthur pit, quartz monzonite assumes a light gray color due to widespread sodic-calcic alteration. A “border-phase quartz monzonite” commonly lies at the contact between the granodiorite and the quartz monzonite. The border-phase quartz monzonite is finer-grained than the quartz monzonite and has more abundant potassium feldspar.

Quartz porphyry dikes that host a large portion of the primary copper mineralization at Anaconda’s Yerington mine are associated with all copper occurrences in the district. The porphyry dikes at the MacArthur Deposit are classified by dominate mafic minerals into quartz biotite porphyry and quartz hornblende porphyry, each subdivided further based on composition and alteration. Dikes contain feldspar crystals and either hornblende or biotite crystals set in an aphanitic matrix. The structures are typically ridge-formers with widths to 50 feet, dip steeply to the north, and follow a penetrative north-northwest (S60°E to S80°E) structural fabric. Narrow (<10 feet) fine grained, post porphyry andesite dikes follow the same NNW structural fabric.

Both Jurassic and Tertiary age andesite dikes in the walls of the MacArthur Pit can be traced from bench to bench and projected across the pit floors. The Jurassic dikes are commonly very fine grained, plagioclase-bearing porphyries that pinch and swell as they fill fractures and intrude the hornblende and biotite quartz porphyry dikes. Tertiary hornblende andesite dikes are similar, but coarser grained than the Jurassic andesite dikes, containing abundant, acicular, black hornblende phenocrysts and occasionally plagioclase phenocrysts. Mid-Tertiary ash flow tuff units unconformably overlay the Mesozoic intrusive rocks in the southeast and western margins of the property.

Mineralization

The MacArthur depositDeposit is part of a large, partially defined porphyry copper system that has been complicated by complex faulting and possible post-mineral tilting. Events leading to the current geometry and distribution of known mineralization includeinclude: 1) emplacement of primary porphyry copper mineralization; 2) supergene enrichment resulting in the formation of a widespread, tabular zone of secondary chalcocite mineralization below outcrops of totally oxidized rocks called a leached cap; and 3) oxidation of outcropping and near-surface parts of this chalcocite blanket, as well as oxidation of the primary porphyry sulfide system coupled with partial remobilization of copper to form the upper zone of oxide copper now exposed in the MacArthur Deposit pit and throughout the MacArthur property.Deposit. Oxide, chalcocite, and primary copper mineralization onat the MacArthur propertyDeposit is hosted in both granodiorite and quartz monzonite, and in lesser amounts within quartz biotite-hornblende (monzonite) porphyry dikes, all of middle Jurassic age. Oxide copper is also hosted in northwest striking andesite dikes less than one to ten feet wide with contacts forming favorable loci for mineralization. Andesite dikes make up less than approximately one to two percent of the host rocks on the property. Fracturing and ground preparation supplied the passage ways for the copper to migrate.

24

Copper oxide minerals are exposed throughout Quaterra’sthe MacArthur property,Deposit, particularly in MacArthurthe pit walls as primarily green and greenish-blue chrysocolla CuSiO3.2H20 along with black neotocite, aka copper wad (Cu, Fe, Mn) SiO2, azurite Cu3(OH2)(CO3) and malachite Cu2(OH2)CO3, while tenorite (CuO) was identified with the electron microprobe (Schmidt, 1996). Copper-enriched limonite was identified by Anaconda as the mineral delafossite (CuFeO2). Chalcocite has been identified in drill holes below the MacArthur Deposit pit and in drilling throughout the property. The sulfides digenite (Cu9S5) and covellite (CuS) have been identified petrographically in drill cuttings from the western part of the property. The oxide copper mineralization is strongly fracture controlled, coating joint and fracture surfaces and within shears and faults. Both green and black copper oxides are frequently found on 1-51 to 5 millimeter fractures, as coatings and selvages and may be mixed with limonite. The fractures trend overall N60°W to N80°W (bearing 300° to 280° azimuth) and generally dip to the north. Limited turquoise is found on the property, mainly in one- to five-millimeter veinlets. On a minor scale, oxide copper mineralization replaces feldspar phenocrysts in the igneous host units, favoring andesite.

A significant amount of chalcocite has been intersected in drillholes. Chalcocite is seen on drill chips or drill core coating pyrite and chalcopyrite as weak to strong coatings and is strongest when occurring around the MacArthur Deposit fault. Chalcopyrite is present as disseminations and veinlets, with or without chalcocite. As much of the historic drilling was stopped at shallow (<400 foot) depths, the scope and extent of chalcopyrite mineralization have not been fully defined.

Both copper oxide and chalcocite mineralization occur over approximately 9,000 feet east-west by 4,500 feet north-south. Copper oxides are structurally controlled coating fractures, joint surfaces, and developed as green or black “streaks” within shears and faults over several feet. Chalcocite may similarly be seen as grayish “streaks” within shears. Oxide mineralization exhibits a generally flat-lying geometry extending with good continuity 150 feet below surface and less continuously up to 600 feet below surface. Chalcocite mineralization generally occurs as flat-lying zones 50 feet or more in thickness, mixed with or below oxide mineralization.

Primary chalcopyrite mineralization occurs irregularly with chalcocite and as porphyry style disseminations or as veinlets in quartz monzonite associated with potassic alteration below both the oxide and chalcocite mineralization. Quaterra’s drilling program in the Gallagher area has delineated a zone of chalcopyrite mineralization that extends over a north-south distance of 2,500 feet. The primary sulfide zone has a defined width of 500 feet and extends to a depth of approximately 650 feet.

Porphyry copper style sulfide mineralization below the low-angle MacArthur Deposit fault zone at the North Porphyry Target has been defined over a distance of 2,500 feet between holes QM-68 and QM-164. Veinlet and disseminated primary chalcopyrite mineralization intercepted at a depth of 485 feet in QM-68 assayed 1.19% copper over a thickness of 110 feet. The same zone in QM-70 averaged 0.82% copper over a thickness of 60 feet at a depth of 420 feet and correlates to a thickness of 15 feet averaging 1.20% at a depth of 770 feet in hole QM-72. QM-100 intersected the sulfide mineralization with 0.58% copper over 65 feet. Approximately 1,000 feet to the north, hole QM-164 intercepted 64 feet of disseminated chalcopyrite mineralization in sodic altered granodiorite averaging 1.31% copper at a depth of 1,673 feet. The intercept includes a high-grade zone of 29 feet averaging 2.21% . Mineralized zones within potassic halos in holes QM-165 to the west and in QM-163 to the east are consistent with those that could fringe a porphyry copper center.

Exploration and Drilling Results

Quaterra acquired the digitized Anaconda exploration and drilling data package in August 2006 and commenced a review of the deposit geology and mineralization model using Datamine software. The data was used to assess the required drilling and sampling to complete a technical report on the MacArthur ProjectDeposit with the objective of preparing a NI 43-101 compliant resource estimate.

25

The lateral zonation of supergene copper minerals visible at the surface, a possible chalcocite blanket to the north of the pit, and a large, pervasive phyllic alteration zone to the north and west of the mine workings, all suggested to Quaterra that the MacArthur depositDeposit could have a potential for growth; both in the form of copper oxides and as primary sulfides in a related porphyry system.

In April 2007, the Company commenced a drilling program to twin approximately 10% of the shallow holes that defined the previously explored copper oxide mineralization at the MacArthur Deposit and to identify extensions of copper oxide and chalcocite mineralization in the vicinity of the open pit. The 20-month drilling program totaled 80,100 feet in 173 holes including 23,900 feet of core in 49 holes and 56,200 feet of reverse circulationRC drilling in 124 holes. The drilling successfully targeted a deeper chalcocite zone in step-out holes from the pit, expanded the known oxide mineralization, and encountered a large, underlying tabular blanket of mixed oxide-chalcocite mineralization that overlies primary chalcopyrite mineralization verified by deeper drillholesdrill holes in the western and northern margins of the drilled area.

Drilling on the MacArthur projectDeposit was suspended through most of 2009 pending receipt of a Plan of Operations (POO)(“POO”) drilling permit. On October 28th 28, 2009,the Company received the approval of the MacArthur Deposit POO and the BLM Record of Decision with a Finding of No Significant Impact (FONSI).Impact. The POO environmental assessment anticipates a total surface disturbance of 200 acres as a result of drilling activities throughout much of the project area.

Quaterra initiated a second phase of reverse circulationRC and deep core drilling in early December 2009. Completed in August 2010, the program tested the northern extension to higher grade acid soluble copper mineralization on 500 foot centers northwest of the pit in-filled on 500 ft centers an undrilled area west of the pit. In the southern Gallagher area, the program confirmed a band of continuous near surface oxide mineralization ranging in thickness from 15 to 60 feet over a distance of 1,900 feet between holes QM-155 and 156.

Three deep holes tested IPRsurface IP/resistivity (“IPR”) anomalies to the north and northwest of the MacArthur Deposit pit where earlier drill holes intersected ore grade porphyry copper style sulfide mineralization below the low-angle MacArthur Deposit fault zone over a strike length of 1,000 feet. Hole QM-100, located 1,400 feet north of QM-68, intercepted porphyry-style chalcopyrite/biotite-chlorite veining at a depth 1,203 feet that assayed 0.58% copper over a thickness of 65 feet below the shallow-dipping MacArthur fault zone. QM-109, spotted on an IPR anomaly, failed to reach projected depth due to fractured, caving ground while QM-99 intersected massive pyrite impregnated breccia and scattered zones of secondary biotite and chlorite alteration; common elements of a porphyry system.

A total of 81,650 feet were drilled in 153 holes including 69,890 feet in 147 RC holes and 11,760 feet in 6 core holes during the 2011 drilling program. The program had the twin goals of enlarging and upgrading the status of the inferred resources through step-out and infill drilling and exploring for primary sulfide mineralization related to a copper porphyry system at depth.

The infill program encountered high grades of continuous chalcocite and copper oxide mineralization in zones averaging 40 feet or more in thickness along the western and northern margins of the deposit in the area referred to as the “Ridge Zone”. To test the high-angle mineralized structures that form an important component of the acid-soluble copper deposit, the program was completed on 250-foot centers in areas with higher grade potential and encountered some of the highest grades and best intercepts of acid soluble copper mineralization ever drilled on the property. Hole QM-187, drilled 2,000 feet north of the MacArthur Deposit pit, intersected 90 feet of predominantly chalcocite mineralization averaging 1.66% total copper (TCu) starting at a depth of 310 feet. This intercept includes 40 feet assaying 3.49% TCu. Hole QM-180 along the northwestern margin of the zone intercepted 40 feet averaging 1.37% TCu at a depth of 360 feet.

Exploration for a deep porphyry system at the MacArthur Deposit intercepted one of the best primary copper intercepts yet identified on the project with hole QM-164 intersecting 64 feet of disseminated chalcopyrite mineralization in sodic altered granodiorite averaging 1.31% TCu at a depth of 1,673 feet. The intercept includes a high-grade zone of 29 feet averaging 2.21% TCu. QM-164 also intercepted a shallower zone of both vein and disseminated chalcopyrite at a depth of 685 feet that averages 0.34% TCu over a thickness of 96.5 feet. QM-164 extended the mineralized zone identified in QM-100 a distance of 1,000 feet to the north where it remains open for extension.

Geophysics

Quaterra Resources contracted three surveys at the MacArthur projectDeposit in 2011 and 2012. A borehole geophysical survey and a surface IP/resistivity (IPR)an IPR survey werewas carried out by Zonge International (“Zonge”) in 2011. A detailed helicopter magnetic survey was flown by Geosolutions Pty. Ltd. (“Geosolutions”) in 2012. These surveys supplement previous geophysical work on the propertyMacArthur Deposit that includes: a 2009 IPR survey carried out by Zonge; a 2007 helicopter magnetic survey carried out by EDCON-PRJ; a series of historic aeromagnetic surveys (1966 to 1975) available in analog form from the Anaconda Archives;Anaconda’s archives; and a series of historic IPR surveys (1963 – 1964) carried out by Kennecott Exploration Services/Company (“Kennecott”), Bear Creek Mining Company and Superior Oil.

The mineralized system at the MacArthur Deposit has an anomalous IP and resistivity response first detected in the Kennecott and Superior Oil IPR surveys in the 1960’s. The Quaterra 2009 and 2011 IPR surveys confirmed the reliability of the earlier surveys and further defined the depth extent of the IP anomalies. The 2009 and 2011 Quaterra surveys confirmed that the 1963-64 Kennecott data is of good quality and is useful for mapping anomalous IP zones within the upper 1,000-1,2001,000 to 1,200 feet from the surface. Below this depth, the older data cannot effectively resolve the bottom of the IP anomalies nor determine if any of the anomalies extend to great depths.

The 2009 and 2011 data sets show this increased depth of exploration is important. Portions of the IP response are flat lying with limited depth extent. However both the 2009 and 2011 surveys have identified anomalous IP responses with depth extent in excess of 2000 feet and possibly feeder zones of the near surface zones. In 2011, two borehole IP surveys were run that demonstrate Quaterra’s ability to explore for deep sulfide responses below the depth of exploration of surface techniques. The modern data maps subtle low resistivity features which are interpreted to be porphyry alteration systems and have identified anomalous IP responses that extend under post-mineral volcanic cover to the north and west of the main MacArthur Deposit system. These buried anomalies are high priority drill targets.

Two high resolution helicopter magnetic surveys were flown over the MacArthur projectDeposit in 2007 (EDCON-PRJ) and 2012 (Geosolutions). The modern, high-resolution data has a broad frequency bandwidth and will be used for 3D modeling and exploring beneath the magnetic volcanic cover.

Sampling, Analysis and Security of Samples

Quaterra has explored the MacArthur propertyDeposit with both reverse circulation (RC)RC and diamond core drilling methods. Reverse circulationRC holes were drilled by Diversified Drilling LLC, Missoula, Montana, USA, DeLong Construction Inc., Winnemucca, Nevada, USA and by Leach Drilling Inc., Silver Springs, Nevada, USA. During 2007-2008 the core drilling was contracted to Kirkness Diamond Drilling of Dayton, Nevada, USA and Kirkness Brothers Diamond Drilling (aka KB Drilling Co, Inc) of Carson City, Nevada, USA. Major Drilling America, Inc., Salt Lake City, Utah, conducted core drilling during 2009-2010. Core drilling during 2011 was contracted to Ruen Drilling Inc, Clark Fork, Idaho, USA. The RC crews ran one 10-1210 to 12 hour shift per day; the core drill crews operated 24 hours per day.

The MacArthur Deposit drilling program is supervised in the field by the project geologist for monitoring recovery, proper sample handling and accuracy in labeling. Drill core (HQ diameter) and reverse circulationRC samples are delivered from the drilling rigs to the core and sample storage facility in Yerington by the drillers at the end of each 12 hour shift for logging and sampling by the project geologists.

At the core storage/logging facility, core is photographed, measured, core recovery calculated, and the rock types, alteration minerals, textural features, structures, veining, and mineralized zones documented. Sample intervals on the first three holes were fixed at five feet. In subsequent drill holes the sample intervals are taken at each of the core runs marked by the driller’s blocks. Exceptions are where full recovery occurs in numerous, short core runs in intervals less than about 6 feet, or where the geologists visually selected sample intervals based on rock type or structure. Sample intervals are measured and marked with permanent marker, orange ribbon and aluminum tag that is stapled to the core tray showing the sample number. Where the core sample is coherent a line is drawn with permanent marker along the stick so that it is sawn in half perpendicular to the “grain” in order to get a representative split. The core is stored on pallets to be picked up by the analytical laboratory.

- 21 -27

When core from the projectMacArthur Deposit arrives at the laboratory, it is split, using a core saw, into halves and one half of each interval is placed into a sample bag that is marked with the sample number. The sample is then dried, crushed to –10-10 mesh, rotary split to 1,000 grams, pulverized to –150-150 mesh, and split to 350 gram pulps. The pulps are assayed for total copper using a 2 gram-3 acid volumetric ore grade atomic-absorption (AA) spectroscopy analysis. The solution from the total Cu analysis is assayed by inductively coupled plasma (ICP) spectrometry for 34 elements. The acid soluble copper oxide (asCu) content of the sample is then analyzed by using a weak, sulfuric acid solution leach of a 1 gram pulp. The acid leachable copper sulfide content is analyzed by using ambient temperature concentrated sulfuric acid and hydrated ferric sulphate to determine Ferric Sulfate Soluble Copper (FSCu) content. Internal quality assurance and quality control procedures include the insertion of standards and duplicates into the sample sequences. Rejects from the previously analyzed samples are also sent to another accredited laboratory for check analyses. The remaining half core is placed back into the core box in its original position and the core boxes are returned to the Yerington core storage/logging facility by the laboratory truck, where it is then stacked and stored in order and by hole number. Reject and pulps are also returned with the core to the Yerington facility for archiving.

American Assay Laboratories (AAL) located in Sparks, Nevada (“AAL”) prepared and assayed samples from the MacArthur Deposit drilling program in 2007. AAL is ISO/IEC 17025 certified and participates in CANMET, PTP MAL certification analyses twice a year and in GEOSTATS, SMA, and IOAG testing twice a year. Core samples from subsequent programs have been prepared and analyzed by ISO17025 compliant ALS Chemex Laboratories in Sparks, Nevada (“ALS Chemex”) and Skyline Assayers and Laboratories (Skyline) in Tucson, Arizona.Arizona (“Skyline”).

The MacArthur reverse circulationDeposit RC drilling program is supervised in the field by the project geologist for sample accuracy, proper handling and accuracy in labeling. Methods and procedures for splitting and packaging of samples are conducted such that the quality of the sample splitting meets or exceeds standards required under NI 43-101 and a chain of custody starts with the drillers collecting, splitting and bagging of RC drill cuttings.

For logging of drilled lithologies, a continuous chip sample is collected in a plastic chip tray over five foot intervals and stored for logging by the project geologists. A 5/16 continuous split of five footfive-foot sample intervals is collected for assaying from 5.2 inch diameter drill holes through a wet splitter mounted on the rig. The samples are placed in sample bags and transported from the drilling rig to the Company’s storage facility in Yerington at the end of each 12-hour shift. The samples are then inventoried by Company personnel, dried, placed on pallets, wrapped in plastic and shipped via United Parcel Service to the Skyline laboratory in Tucson, Arizona for sample preparation and assaying. Rejects and pulps are returned to the Yerington facility for archiving.

Skyline Assayers & Laboratories is accredited by the American Association for Laboratory Accreditation (A2LA - certificate no. 2953.01) in the Chemical field of Testing. Skyline is a recognized industry leader for all types of base metal, ferrous and non-ferrous analysis including high quality ore-grade assays, sequential copper analyses of ores, and umpire assays of metallurgical products. The Tucson laboratory has provided analytical service to the copper mining industry for over 70 years.

At Skyline, the RC samples are crushed to plus 75% passing a -10 mesh, split and pulverized at the Skyline laboratories for assay using analytical techniques as described for the core drilling program. Internal quality assurance and quality control procedures include the insertion of standards into the sample sequences. Rejects from the previously analyzed samples are sent to ALS Chemex Laboratories in Sparks, Nevada for check assays.

Mineral Resources

Tetra Tech completed an updated National Instrument (“NI”)NI 43-101 compliant independent resource estimate for the MacArthur PEADeposit preliminary economic assessment (the “MacArthur Deposit Resource Estimate”) titled “MacArthur“MacArthur Copper Project – Amended NI 43-101 Technical Report Preliminary Economic Assessment, Lyon County, Neveda,Nevada, USA” and dated January 17, 2014 (effective date May 23, 2012). At a 0.12% cutoff, the tonnage of the measured oxide and chalcocite resourcewas 71,82971.8 million tons at 0.218% copper containing 313 million lbs. of copper, the indicated oxide and chalcocite resourcewas 87,26487.3 million tons at 0.208% copper containing 362 million lbs. of copper, and the inferred oxide and chalcocite resource was 243.4 million tons at 0.201% copper containing 979.5 million lbs. of copper.

- 22 -

MacArthur’sThe MacArthur Deposit’s indicated sulfide resource at a 0.15% cutoff is 1.1 million tons averaging 0.292% copper containing 6.4 million pounds of copper and the inferred sulfideresource was 134.9 million tons averaging 0.283% copper containing 764 million lbs. of copper.

²All estimated resources are shown using a 0.12% and 0.15% copper cutoff for oxide and sulfide respectively
³Minor rounding errors may occur
⁴Amended NI 43-101 Technical Report Preliminary Economic Assessment - Issue date: 17 January 2014 Effective Date: 23 May 2012

Tetra Tech used 0.12% Cu (or TCu) as the base case cutoff grade for the leachable resource while applying a base case a 0.15% Cu cutoff grade for the primary sulfide resources. Both of these values are believed representative of actual operating cutoff grades in use as of the date of this report. It is the conclusion of Tetra Tech that the MacArthur Mineral Resources meet current CIM definitions for classified resources.

The updated mineral resource estimate was generated using drill hole sample assays results and the interpretation of a geologic model which relates to the spatial distribution of copper in the MacArthur deposit. Interpolation characteristics have been defined based on geology, drill hole spacing and geostatistical analysis of the data. A block size of 25 feet by 25 feet by 20 feet and an assay composite length of 10 feet were defined to best reflect both the drill hole spacing and current geologic model.

The database provided by Quaterra contained the pertinent drill hole and assay information for the MacArthur Copper deposit. The database contained 737 drill holes of which 676 drill holes from Quaterra and Anaconda (sometimes referred to as the Metech holes) were used. The 61 holes removed included holes with limited or no information on the assays (Pangea Gold 1991, Superior, USBM 1952, Anaconda 1955-57), and six Quaterra holes outside the model limits. Of the 676 holes used, there are 280 Anaconda (Metech) RC holes and 396 Quaterra holes (58 core and 338 RC holes). These drill holes traversed 257,895 feet, producing 51,258 total copper sample assay values at a nominal five feet in length. The variables available in the database are for total copper from Quaterra and Anaconda intervals, and acid-soluble copper, a limited number of ferric sulfate soluble (QLT) copper assays and a very limited number of cyanide leach copper assays from Quaterra holes.

- 23 -

A total of 22 (21 directional and a omni-directional) variograms were calculated using MicroModel® for each MinZone within each area. The program searches along each direction for data pairs within a 12.5 -degree window angle and five-feet tolerance band. All experimental variograms are inspected so that spatial continuity along a primary, secondary and tertiary direction can be modeled. Each variogram model was then validated using the “jackknifing” method. This method sequentially removes values and then uses the remaining composites to krige the missing value using the proposed variogram.

To classify the total copper resources Tetra Tech used an approach that takes into account the spatial distribution of the drilling, the distance to the nearest data points used to estimate a block, and finally the relative kriging error generated by the estimate. Tetra Tech has found this approach to be very robust and provide highly reproducible results.

Metallurgy

The MacArthur ProjectDeposit has a long history of metallurgical testing from 1976 through 2011 including bottle roll and column leach testing and full-scale heap leach operations. Anaconda performed the first test work in 1976 and multiple subsequent owners continued test work through 2011. The most comprehensive test work was performed by Quaterra during 2010 and 2011. Quaterra contracted METCON Research of Tucson, Arizona to run a substantial number of bottle roll leach tests along with 32 column leach tests, on samples from 27 large diameter (PQ) size core drill holes. These drill holes are generally representative of the MacArthur ProjectDeposit mineral resources. The test work, both historic and that most recently performed, shows the mineralized material is amenable to standard heap leaching with good copper extraction.

Considering both recent and historical test work, along with information from previous mining operations at the MacArthur site, the design basis for the M3 MacArthur Copper Project May 23, 2012 Preliminary Economic Assessment (PEA) considers a ROM heap leach operation with processing of the pregnant leach solution (PLS) through traditional solvent extraction / electrowinning (SX/EW). Copper extraction is predicted to range between 60 and 70 percent depending on material type. Acid consumption projections range between 30 and 35 pounds of acid per ton of material. The historic MacArthur Pit contains 133 million tons of oxide material which is predicted to yield 70% copper extraction with acid consumption of 30 pounds of acid per ton of material leached. Material from the MacArthur pit is predominately mined and processed over the first 7 years of operation.

The leach pad will be constructed using an HDPE liner system meeting Nevada requirements (NR 455). Conventional solvent extraction will be used. Electrowinning will include permanent mother blank stainless steel technology and harvesting of Grade A copper cathode on a 7 day pull schedule. All process facilities will incorporate proven industry standard designs and equipment.

The Qualified Person for the metallurgical portion of the MacArthur Copper Project PEADeposit Resource Estimate is Dr. Richard Jolk of Tetra Tech.

Preliminary Economic Assessment

M3 Engineering & Technology Corp. (“M3”) of Tucson, Arizona (“M3”) completed a preliminary economic assessment (“PEA”) for the MacArthur projectDeposit on May 23, 2012 and titled “MacArthur“MacArthur Copper Project – Amended NI 43-101 Technical Report Preliminary Economic Assessment Lyon County, Neveda,Nevada, USA” (the “MacArthur Deposit PEA”). The MacArthur Deposit PEA was amended and restated on January 27, 2014. The study concluded that the project has potential for development as a large-scale copper oxide heap leach operation that would provide long-term cash flows for a relatively modest capital outlay.

A PEA should not be considered to be a pre-feasibility or feasibility study as the economics and technical viability of the Project have not been demonstrated at this time. Mineral resources that are not mineral reserves do not have demonstrated economic viability .viability. A PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too geologically speculative at this time to have economic considerations applied to them to be categorized as Mineral Reserves. Thus, there is no certainty that the production profile concluded in the MacArthur Deposit PEA will be realized. Actual results may vary, perhaps materially.

The MacArthur Deposit PEA set out the following key project parameters:

Mine operating costs were provided by Independent Mining Consultants Inc. (“IMC”) of Tucson, Arizona (“IMC”), based on an average 41,000 ton per day mine plan.

The project financials were enhanced by including in the above cash flows a sulfuric acid plant at the site compared to purchasing and transporting acid to the site. An on-site acid plant provides more long term certainty for the highest operating cost item (sulfuric acid), reduces the requirement for purchased electric power, and would leverage future consolidation and development of other oxide deposits in the District.

The SX/EW capital cost estimate was prepared based on recent M3 in-house information of similar SX/EW facilities. It includes the heap leach pads, SX/EW facility and tank farm based on a design flow rate of 10,400 gal/min. Additional upfront capital costs were included for mining equipment and infrastructure improvements (power, water, roads) needed at the site. Capital costs are considered accurate to -20% to +25%.

The Qualified Person for the preliminary economic assessmentMacArthur Deposit PEA is Mr. Rex Henderson with M3. The Qualified Person for the mining portion of the reportMacArthur Deposit PEA is Herb Welhener of IMC. The NI43-101 MacArthur Copper Project may 23, 20132012 PEA is available at www.sedar.com.

Future Plans

The results of the PEA are being used to determine what additional drilling will be required to bring the project to a prefeasibility status and to evaluate the potential to integrate the MacArthur resource into a larger operation that includes the Yerington Copper resource. This stage of a project generally includes additional infill and condemnation drilling, metallurgical testing and geotechnical work as well as environmental studies, permitting and engineering.

Some of the options being considered to add additional value to the project include:

In August 2014, as part of the Freeport Nevada Option Agreement, the MacArthur projectDeposit was transferred intoto SPS, a wholly owned subsidiary of Quaterra Alaska.Alaska Inc.

Acquisition and StakingOn January 10, 2018, Quaterra announced that it has initiated preparation of Claimsa comprehensive prefeasibility study at MacArthur. In November 2017, Quaterra approached M3 to review opportunities to optimize the near-term production potential at MacArthur as laid out in the 2012 PEA.

The Yerington Copper project property totals approximately 11 square miles. The project mineral rights consist of 2,768 acres of fee mineral properties2012 PEA identified several areas for potential improvement, including additional metallurgical work and patented mining claims as well as 201 unpatented lode and placer claims totaling 4,153 acres on lands administered by the US Department of Interior, Bureau of Land Management (BLM). The total reflects the transfer of 345 claims from Quaterra’s wholly owned subsidiary, Singatse Peak Services LLC (SPS)focused resource drilling. In addition, M3’s review indicated that it may be more economic to Quaterra Alaska’s MacArthur project in July 2012.

On May 1, 2007, SPS received the bankruptcy court approval for the acquisition of certain assets of Arimetco, Inc. (Arimetco) in the Yerington Mining District, subject to completion of due diligence. The purchase price comprised US$500,000 cash, 250,000 of the Company’s common shares and a 2% net smelter return royalty capped at US$7.5 million dollars on production from any claims owned by the Company in the Yerington and MacArthur mine areas.

Private land, patented claims, and 23 unpatented mining claims related to the Yerington Copper project were acquired by SPS from the Arimetco bankruptcy court in April, 2011. The acquisition followed three years of due-diligence studies and negotiations with state and federal agencies and the receipt of Bona Fide Prospective Purchaser (BFPP) letters from the US Environmental Agency (EPA), the Nevada Division of Environmental Protection (NDEP) and the BLM to protect SPS from liability emanating from activities of the former mine owners and operations.

Singatse Peak Services (SPS) purchased the Anaconda Mine and MacArthur Mine properties along with the appurtenant ground water rights in 2011. SPS owns a total of 8,621 acre-feet/yr of primary ground water rights which have senior priority standing. The purchased water rights are primary ground water rights specifically permitted for mining and milling. These water rights have significant value. Recent sales of primary ground water in Mason Valley Nevada have sold for over $3,000 per ac-ft.

Private properties related to the Arimetco acquisition are located in Township 13 North, Range 25 East in Sections 4, 5, 8, 9, 16, 17, and 21, and patented claims are located within Township 13 North, Range 25 East in Sections 16, 17, 19, 21, 31, and 32 and in Township 13 North, Range 24 East in Sections 22-25 and 36. An additional 434 unpatented claims in Sections 1, 2, 11-13, 22- 27, 35, and 36 Township 13 North, Range 24 East and in Sections 4- 9, 16- 21, and 30-32 Township 13 North, Range 25 East, Mount Diablo Base & Meridian were staked prior to or subsequent to the acquisition by SPS.

Expenditures to Date

Acquisition costs incurred by the Company to December 31, 2014 were $3,902,149 (net of recovery under the Option Agreement) (2013 - $3,368,518) and exploration expenditures were $7,358,911 (2013 - $7,047,920) for a total of $ 10,571,676 after accounting for recoveries allocated to the property recied from Freeport McMoRan Nevada LLC under the option agreement (2013 - $10,416,438).

Location, Access and Infrastructure

The Yerington Copper Property is located near the geographic center of Lyon County, Nevada, USA, along the eastern flank of the Singatse Range. The property centers on the historical Yerington open pit mine, flanked on the west by Weed Heights, Nevada (a small private community; the original company town of The Anaconda Company) and on the east by the town of Yerington, Nevada. The property is easily accessed from Yerington by a network of paved roads that were used as principal transportation and access routes during the former operating period of the Yerington Mine. SPS controls approximately 8,600 acre feet of groundwater rights and the Yerington pit contains an estimated 37,000 acre feet of water. Power is available on site at the Yerington Mine area. Nevada Energy operates a 30 million kW propane-fired, electrical generating power plant within ten miles of the site. The power infrastructure at the Yerington Mine site is expected to be readily available for a future mining operation due to the historical mine operations at the site. Topographic coverage is on US Geological Survey “Yerington” and “Mason Butte” 7.5’ topographic quadrangles. The nearest major city is Reno, Nevada, approximately 80 miles to the northwest.

History

Recorded production in the Yerington mining district dates back to 1883 (Moore, 1969) as prospectors were attracted to and investigated colorful oxidized copper staining throughout the Singatse Range. Knopf (1914) reported that oxidized copper cropped out at the historic Nevada-Empire mine located above the south center of the present-day Yerington open pit. Knopf does not show or reference other mines or prospects that are underlain by the Yerington open pit footprint, as gravel and alluvial cover obscure bedrock over an approximate 0.75 -mile radius around the Nevada-Empire Mine.

Information is sparse for the period from Knopf’s reporting in 1914 until World War II, although it is likely that lessees worked the Nevada-Empire during spikes in the copper price. Private reports (Hart, 1915 and Sales, 1915) describe ore shipments and planned underground exploration from a northwest striking, southwest dipping structure at the historic Montana-Yerington Mine area located approximately one mile west of the present-day Yerington pit.

During the 1940s, The Anaconda Company (Anaconda), at that time one of world’s major copper producers, outlined a 60 million-ton resource over the Yerington pit. During the early 1950s, the US government, citing the need for domestic copper production, offered “start-up” subsidies to Anaconda to open a copper mine in the Yerington district. Anaconda sank two approximately 400-foot-deep shafts in the present-day open pit and drove cross cuts to obtain bulk samples of oxidized rock for metallurgical study. Anaconda began operating the Yerington Mine in 1952 and mined continuously through 1979, producing approximately 1.744 billion pounds of copper from an ore body that contained 162 million tons averaging 0.54% Cu. Approximately 104 million tons of this total were oxidized copper ore that was “vat-leached” withbuy sulfuric acid in 13,000-ton cement vats on a seven day leach cycle. Sulfide ores were concentrated on site in a facility that was dismantled and sold following termination of mining in 1979.

In 1976, all assets of The Anaconda Company, including the Yerington Mine, were purchased by the Atlantic Richfield Company (ARCO) which in 1979 shut down dewatering pumps in the pit and closed the Yerington Mine due to low copper prices. In 1982, ARCO sold the entire Yerington Mine complex and Weed Heights town site to Mr. Don Tibbals of Yerington, Nevada, who scrapped the plant and equipment. At closure, before dewatering pumps were shut off, the Yerington mine plan hosted a pre-stripped, non NI 43-101 compliant historic “reserve” of 98 million tons averaging 0.36% Cu containing approximately 696 million pounds of copper (K. L. Howard, Jr., Anaconda Internal Memo, 1979) within the ultimate pit design. The (Howard, 1979) estimate was prepared from a geologic section calculation using a 0.2 %TCu cut-off grade. A qualified person has not done sufficient work to classify these historic estimates as a current mineral resource and Quaterra does not treat them as such. Although the 1979 estimate contained no classification for measured, indicated, or inferred resources as defined by NI 43-101, the total estimate compares favorably to a Tetra Tech NI43-101 compliant independent resource estimate completed in February 2012. An additional 22.8 million tons of material containing 136.8 million pounds copper was identified adjacent to the pit in this historic estimate. The (Howard, 1975) memo addressing this material is considered reliable because it cites mine reconciliation calculations and geologic projections from drill holes using a 0.2% Cu grade cut-off in an internal Anaconda memo by T. Leigh to W.C. Norem (1979).

In 1989, Arimetco Inc. (Arimetco) purchased the mine property from Tibbals, commissioned a 50,000-pound-per-day solvent extraction/electrowinning plant, and began heap leaching “sub-grade” dump rock stripped from the Yerington pit by Anaconda. Arimetco also added an unknown tonnage of “vat leach tailings” (minus 3/8 inch oxidized tailings leached during Anaconda’s operation) to some heap leach pads (HLP's) as well as trucking oxidized ore from the MacArthur property located approximately five miles north of the Yerington mine site. Arimetco produced some 95 million pounds of copper from 1989 to 1999 before declaring bankruptcy due to low copper prices and abandoning the property.

Soil and groundwater contamination, alleged to stem from the former mining operations at Yerington, have been identified on the property. As a result, a portion of the property acquired by SPS in 2011 is now under the jurisdiction of the EPA. Liability for the contamination on site is the responsibility of a third party which is actively engaged in remedial investigation and remediation activities under the supervision of the EPA.

In order to establish SPS’s position and rights, the acquisition by SPS of the Arimetco properties required a series of rigorous environmental, legal, and technical due diligence studies. The Chambers Group Inc. and Golder Associates Inc. completed a Phase 1 Environmental Site Assessment Report to allow SPS to establish liability protection as a bona fide prospective purchaser (BFPP). Prior to closing on the property, SPS received letters from the Nevada Department of Environmental Protection (NDEP), US Bureau of Land Management (BLM) and the USEPA indicating the post-closing requirements then applicable to the Site for SPS to maintain its defense to liability as a BFPP regarding the activities of the former mine owners and operators.

In September 2012, SPS entered into a voluntary agreement with the U.S. Environmental Protection Agency (EPA) to participate in upgrading the system which manages fluids from the historic mining operation at the Yerington mine site. In exchange for SPS's participation in this work, the Company obtained a site-wide 'Covenant Not to Sue' for the contamination left at the site by former owners and operators of the historic mine operations.

The agreement provides for immediate environmental improvements to the site and allows SPS to continue exploration at the site while working cooperatively with the EPA, Nevada Department of Environmental Protection and the community. The Agreement's 'Covenant Not to Sue' strengthens SPS's 'Bona Fide Prospective Purchaser Defense' against liability resulting from the contamination at the site prior to SPS's purchase.

The first phase of the fluid management project was completed in Q4 of 2012. The Company co-funded the repairs to the on-site fluid management system (FMS) by the EPA as well as the relining of one of the system ponds. During Phase 2 of the project, the Company completed a study of the FMS to determine what additional repairs or other modifications are necessary to ensure that the system is capable of handling the fluids from the former mine operations for a period of five years. The Study was completed by the Company’s contractor in June 2013. EPA decided not to implement the five-year capacity alternative recommended in the Study. Rather, EPA decidedmarket than to build now pondsan acid plant to address the FMS capacity issues.process purchased sulfur. The Company decided not to fund construction of the additional ponds. Rather, the Company agreed to provide property at the site to construct the new ponds.

In September 2014, SPS submitted to EPA a Final Report that documented the work SPS performed under the EPA Agreement. SPS incurred costs of US$93,254 during calendar year 2014 which included the final payment to the EPA for the Work to Be Performed and Payment of Response Costs as defined in the Agreement. On January 7, 2015, the EPA issued a Notice of Completion to SPS confirming that the obligations of the Work to Be Performed and the Payment of Response Costs sections of the Settlement Agreement had been met. With the issuance of the Notice of Completion, SPS believes it does not have further obligations under the Agreement, except for those as a landowner and as a BFPP.

Geology and Mineralization

The Yerington property includes both the Yerington Deposit (Yerington Mine) and a portion of the Bear Deposit which represent two of three known porphyry copper deposits in the Yerington copper district. The porphyry systems are hosted in middle Jurassic intrusive rocks of the Yerington Batholith. Unless noted otherwise, the following discussions refer to the Yerington Deposit

Mineralized porphyry dikes associated with three phases of intrusive activity related to the Yerington Batholith form an elongate body of mineralization that extends 6,600 feet along a strike of N118ºE. The mineralization has an average width of 2,000 feet and has been defined by drilling to an average depth of 250 feet below the Yerington Mine pit bottom at the 3,800-ft elevation. Because of the economic constraints of low copper prices at the time, many of the 792 historic Anaconda drill holes used in the SPS study were stopped in mineralization and very few were drilled below the 3,400-ft level where the porphyry system remains nearly unexplored.

Only four historic holes have actually explored the deep vertical projection of copper mineralization in the pit. Three of the holes were drilled along a single N-S oriented section through the center of the pit. According to M. T. Einaudi in an internal 1970 Anaconda report, the deep drilling program defined a series of nested, concave upward, grade shells that are elongated down the N 70º dip of the dikes with the 0.2% Cu zone extending to approximately the 2,600-ft level; an overall dip distance of 2,200 feet. Although the program encountered an increasing ratio of pyrite to chalcopyrite, there was no indication of a “barren core”, the porphyry dikes showed a “remarkable continuity” down dip and molybdenum mineralization became more abundant with increasing depth.

The orientation of the Yerington Deposit is due to mid-Tertiary extensional faulting that rotated the near vertically-emplaced batholith 60° to 90° westerly. The west to east dilation-displacement positioned the porphyry copper deposit on its side, resulting in a cross section of the of the porphyry system visible in the pit with its top toward the west end. Mining has revealed an alteration geometry displaying the original pyrite-rich cap (present-day leached sericite-limonite on the west end of the Yerington pit, grading downward easterly to quartz-sericite-pyrite alteration and potassic alteration in the central portion of the pit, continuing to a soda-flooded root zone at the eastern end).

Secondary oxide copper formed much of the upper Yerington Deposit. Chrysocolla was the dominant copper oxide mineral, occurring as fracture coatings and fillings to a depth of approximately 400 feet below the surface. Below the 4,100-ft level, chalcopyrite is the dominant copper sulfide mineral with minor bornite primarily hosted in A-type quartz veins in the older porphyry dikes. The un-mined mineralized material below the current pit bottom is primarily of chalcopyrite mineralization.

Exploration and Drilling Results

Exploration work on the Yerington Copper project commenced with a technical review of all available historical information relating to mineralization in and around the Yerington pit. A huge inventory of Anaconda data was available at the Anaconda Collection – American Heritage Center, University of Wyoming at Laramie. Approximately 10,000 pages of drill hole records from the library were scanned. The records included drill hole lithology, assays, and/acid plant represented $65.4 million or survey coordinates for almost 800 drill holes. Although some holes contained only lithologic or assay summary information, 892 holes contained adequate detailed assay, hole location and orientation information to be used in a resource estimation. Core from historical drilling left on site by Anaconda was photographed, described and selected intervals from 45 Anaconda core holes were shipped to Skyline Labs for re-assay.

- 28 -

Information obtained from the review of historical information was used to guide a two-pronged program of drilling during the last half of 2011. A total of 21.887 feet were drilled in 42 holes. The core holes and four RC holes were drilled to twin Anaconda core holes, while the remaining RC holes were targeted for expansion of mineralization laterally and below historic drill intercepts along the perimeter of the Yerington pit to support a NI 43-101 compliant resource estimate and technical report.

The data review and drilling results of the 2011 program clearly indicated that mineralization at Yerington is open to depth and along strike. Many of the historic holes in the pit were stopped in mineralization. Drill hole intercepts along the western edge of the pit are some of the best in the SPS database. Twin hole SP-04, drilled by SPS at the northwest end of the pit, intercepted 524.5 feet averaging 0.35%TCu starting at a depth of 228 feet including 88 feet of 0.69%TCu at a depth of 265 feet. Exploration hole SP-36, located along south central margin of the pit intercepted 95 feet averaging 0.28% TCu at a depth of 230 feet. Details of the 2011 drilling program are in the NI 43-101 compliant technical report for the Yerington Copper Project completed by Tetra Tech, Inc. of Golden, Colorado in February 2012.

A drilling program to sample residuals (historic dumps and tailings) at the Yerington site was completed in September 2012. A total of 9,585 feet of sonic drilling in 95 holes have provided material for the characterization of the vat leach tails, heap leach pads, and the W-3 sub-grade waste dump. Selected samples were sent to Metcon Labs in Tucson, Arizona for metallurgical testing. These residuals have been historically estimated to total 124 million tons of mineralized material. The residuals are referenced in the MacArthur PEA and the Yerington Mine 43-101 Resource reports, as “mineralized material” and therefore are neither a NI 43-101 compliant resource nor a historical resource. Additional details regarding the residuals are described in the NI 43-101 Technical Reports. The residuals are not included in the resource estimate at the Yerington site or in the PEA or resource estimate at the MacArthur site.

Sampling, Analysis and Security of Samples

Tetra Tech’s review of sample preparation, handling, analyses, and security procedures for the Yerington drilling and sampling program has determined that the Company’s current practices meet NI 43-101 and CIM defined requirements.

Samples taken during the period from 1952 to 1979, when Anaconda operated the Yerington Mine, including samples used for the determination of mine head grades, lithology, densities, and metallurgical performance were determined by Tetra Tech to be representative of the deposit. While no details are available regarding Anaconda’s exact assaying protocol and quality control during the period the Yerington copper mine was operating, public records of profit and cost confirmed that the techniques and procedures implemented conformed to industry standards for that era.

SPS explored the Yerington Mine Copper property with both RC and diamond core drilling methods. The drilling program was supervised in the field by the project geologist for monitoring recovery, proper sample handling and accuracy in labeling. Approximately 4,300 samples were collected during the 2011 program and shipped for sample analyses. The samples were analyzed for total copper (TCu), gold, and a 47-element trace element package. Samples representing oxide mineralization and acid soluble sulfide copper were also analyzed for acid soluble copper and for ferric sulfate soluble copper. Rock quality designations (RQD) and magnetic susceptibility measurements were taken on all core which was photographed following geologic logging.

The RC samples are collected in a conventional manner via a cyclone and standard wet splitter, placed in cloth bags that are pre-marked by SPS personnel at five-foot intervals and include a numbered tag inserted into a plastic bag bearing the hole number and footage interval. Collected samples, weighing approximately 15 to 20 pounds each, are wire tied and then loaded onto a ten-foot trailer with wood bed allowing initial draining and drying. Each day SPS personnel or the drillers at the end of their shift, haul the samples to SPS’s secure sample preparation warehouse in Yerington, Nevada where the samples are dried, loaded on plastic lined pallets, weighed, and trucked by Skyline Assayers & Laboratories (Skyline) personnel to Skyline’s sample preparation facility in Battle Mountain, Nevada. A chain of custody form accompanies all shipments from Yerington to Battle Mountain. Once Skyline preps each sample in its Battle Mountain facility, approximately 50-gram sample pulps are air-freighted to Skyline’s analytical laboratory in Tucson, Arizona for analyses and assay.

- 29 -

Samples from the core drilling program are handled in a similar manner. Core samples with a diameter of approximately 2.75 -inches (HQ) are placed in wax-impregnated, ten-foot capacity cardboard boxes and delivered to SPS’s secure sample warehouse in Yerington, Nevada by the drill crew following each 12-hour shift. The core is logged by a SPS geologist who marks appropriate sample intervals (one to nominal five feet) with colored flagging tape. Lines are marked along the length of core with red wax crayons to indicate where the core piece should be sawed. Each core box, bearing a label tag showing drill hole number, box number, and box footage interval, is then photographed. Rock quality designations (RQD), magnetic susceptibility, and recovery measurements are taken. Core is then loaded on a pallet, shrink wrapped, and secured with wire bands for trucking by Skyline personnel to Skyline’s sample preparation facility in Battle Mountain, Nevada. The core is sawed in half by Skyline personnel, one half designated for sample preparation/assay, the second half placed in its core box for return to SPS. Chain of custody procedures for core shipments picked up by Skyline at the SPS core shed follow the format for RC samples.

Drilling samples from the Yerington Copper Project were analyzed by Skyline in Tucson, Arizona, which is accredited by the American Association for Laboratory Accreditation (A2LA - certificate no. 2953.01) and by ISO17025-compliant ALS Minerals Laboratories in Sparks, Nevada. SPS implements a quality assurance and quality control assay protocol whereby either one blank or one standard is inserted with every ten samples into the assay stream. Rejects from the previously analyzed samples are sent to ALS Minerals in Reno, Nevada for check assays.

Mineral Resources

Tetra Tech, Inc. of Golden, Colorado completed a NI 43-101 compliant independent resource estimate and technical report update for the mineralization in and around the historic Yerington Mine titled “NI 43-101 Technical Report Mineral Resource Update Yerington Copper Project Lyon County, Nevada” and dated January 3, 2014 (effective November 20, 2013), which supersedes its previous report completed in February 2012. The updated resource is based upon an additional 232 historic Anaconda holes unavailable when the previous report was completed. The current resource now includes over 800 boreholes.

These additional holes are well distributed throughout the deposit and provided infill and extensional information to the previously used data, allowing upgrades in classification, improved grade estimate and a new resource definition.

The increases to the February 2012 resource are as follows. Using a 0.12% TCu copper cutoff, measured and indicated oxide and chalcocite resources increased 28% in tons, 9% in grade, and 37% in pounds of contained copper while the inferred resource increased 5% in tons, 14% in grade, and 21% in contained copper. Using a 0.15% TCu copper cutoff, the primary measured and indicated resources increased 12% in tons, 12% in grade, and 25% in contained copper while the inferred resource increased 4% in tons, 11% in grade, and 13% in contained copper.

Using a cutoff grade of 0.12%, the Yerington Mine’s measured and indicated acid-soluble oxide/chalcocite mineralization includes a measured and indicated resource of 23.5 million tons averaging 0.25% TCu (118 million pounds of copper) and an inferred resource of 25.9 million tons of 0.23% TCu (118 million pounds of copper). Using a cutoff of 0.15% TCu, the measured and indicated primary copper resource contains 105 million tons averaging 0.30% TCu (633 million pounds of copper) and an inferred primary copper resource of 128 million tons of 0.23% TCu (600 million pounds of copper).

The updated tons, grades, and pounds are presented in the table below as well as the percent increase from the February 2012 resource estimate.

⁴ NI 43-101 Technical Report, Feb. 17, 2012

Based on benchmarking of the Yerington Deposit to similar deposits, Tetra Tech has determined that reasonable base case cutoff grades for the leachable (oxide/chalcocite) SX/EW recoverable copper and for flotation recoverable primary sulfide resources are 0.12% TCu and 0.15% TCu, respectively.

The results of the 2013 NI 43-101 compliant resource estimate compare favorably to the estimates of copper remaining in and around the Yerington pit after the mine shut down (K.L. Howard, Jr., Anaconda Internal Memo, 1979). The 1979 estimate contained no classification for measured, indicated, or inferred, so direct comparison can only be made when considering all classes of the current estimate, but was reported at 121 million tons with an average grade of 0.34% TCu.

The 1979 estimate cited approximately 84% of the total contained copper (696pre-production capital costs of $232.7 million poundsin the 2012 PEA.

Following the review and a final evaluation, Quaterra intends engaging M3 to complete a prefeasibility study in order to add more certainty to the economic potential of copper in 97.8 million tonsMacArthur with an average grade of 0.356% Cu)a view towards advancing the project toward development. Specifically, as being within the original Anaconda pit design, suggesting that a significant portionpart of the Yerington resource may be mined without a pushback or major changesprefeasibility study M3 and others will focus on:

Quaterra has also engaged Independent Mining Consultants to update the upper walls of the Anaconda pit.

The current Tetra TechMacArthur mineral resource estimate is based upon SPS's 2011 drilling as well as 792 historic drill holes taken from approximately 10,000 scanned pages of assay and/or geologic data which were reviewed and digitally recorded by SPS personnel and from 57 Anaconda cross sections in use atincorporating the time of mine closure. The digital data entry was validated by Tetra Tech against historic sections and was considered to be compliant, based upon results of 18 twin holeswork completed since the 2012 PEA, re-evaluate the assumptions in the 2012 PEA, and 5,446 feet of core from Anaconda holes which were assayed by SPS. The twinned drill intercepts statistically confirmed thatidentify additional opportunities to enhance the new compliant data support use ofmine plan. Quaterra will have to raise additional funds to complete the historical data, as did the new core assays which were well within the expected norms for corroborating the old with new data.prefeasibility study.

The Tetra Tech resource estimate is included with a description of the project history, geology, mineralization, sampling procedures, and laboratory Quality Assurance/Quality Control procedures. The NI 43-101 Technical Report is available at www.sedar.com. The Qualified Person for the Yerington Copper Project resource estimate and the technical report is Rex Clair Bryan, Ph.D., Sr. Geostatistician for Tetra Tech, Golden Colorado.

Future Work Plans

Quaterra believes the Yerington Copper Project has potential for significant additional copper resources. Historic and current drilling data indicate that horizontal and vertical limits to the mineralization at the Yerington Mine have not yet been found. Additional exploration and in-fill drilling is planned to both expand and upgrade the current NI 43-101 compliant copper resources of the project.

- 31 -30

Future drilling will target the pit area below the 3,000 feet level (elevation) where only four deep historic holes (D158, D152, D174, and V2-28-33) have actually explored the deep vertical projection of mineralization. Three of five holes drilled along a N-S oriented section through the pit during the period of 1969 to 1970 defined a series of nested, concave upward, grade shells that are elongated down the N 70º dip of the dikes with the 0.2% Cu zone extending to approximately the 2,600 level; an overall dip distance of 2,200 feet. Although the program encountered an increasing ratio of pyrite to chalcopyrite, there was no indication of a “barren core”, and the porphyry dikes showed a “remarkable continuity” down dip. The drilling data also established a 250 to 500 foot thick zone of fracture hosted and disseminated molybdenum mineralization that wraps around the sulfide zone near the chalcopyrite/ chalcopyrite-pyrite transition. IP geophysics in the pit area is also being considered to target deep holes to explore this keel of the Yerington porphyry system.

A review of historic information and additional metallurgical testing is planned for both the residuals and core from sulfide mineralized zones below the pit and oxide copper mineralization in the vicinity of the mine. The test results will be used in an economic assessment of the property and an assessment of the merits of a possible integration of the MacArthur and Yerington operations.

c. Bear Deposit

A portion of the Bear deposit lies on the northeast portion of the Yerington Mine property that was acquired with the SPS purchase of Arimetco’s assets from bankruptcy court. In December 2013, Quaterra announced the signing of four option agreements totaling 1,305 acres of private land north and east of the Yerington Mine Site that covers additional portions of the Bear copper deposit.Deposit. In May 2015, the Company entered into an option agreement to acquire a fifth property covering approximately 1,020 acres of additional private land covering a portion of the Bear Deposit. Under the terms of the five option agreements, Quaterra (now SPS) has an exclusive right to exploreacquire these parcelsproperties with all mineral rights and has an option to purchase the properties, surfacecertain water rights, and supplemental storage water rights.to explore these parcels.

The Bear depositDeposit was discovered in 1961 by Anaconda condemnation drilling in the sulfide tailings disposal area and was further delineated in the 1960s and 1970s. Currently the deposit is open in several directions and has never been consolidated under a single owner. A part of Quaterra’s recently acquired acreage was not previously accessible for exploration and is adjacent to the highest grade mineralization discovered during previous exploration of the area.

Historical information compiled for the Bear Deposit includes 126,400 feet of drilling in 49 drill holes that define a mineralized system covering an area of at least two square miles. The portion controlled by Anaconda in the 1960s covered approximately 25% of this area and includes an estimated 500 million tons of mineralized material averaging 0.40% copper (Dilles and Proffett, 1995). The Bear Deposit tonnage and grade estimate is historic in nature. A qualified person has not done sufficient work to classify this historic estimate as a current mineral resource and Quaterra does not treat it as such. In order to do so, this estimate will have to be confirmed by additional drilling.

The Bear depositDeposit is a large porphyry copper system that occurs below 500 to 1,000 feet of valley fill and volcanic rocks of Tertiary age. Mineralization occurs predominantly in quartz monzonite, border phase quartz monzonite, and quartz monzonite porphyry dikes of Jurassic age. There does not seem to be any relation between the Jurassic rock type and the sulfide occurrence. Copper mineralization occurs most commonly as chalcopyrite with minor bornite within platings and veinlets of fresh feldspar and shreddy biotite. No copper oxide mineralization is present and only minor occurrences of chalcocite have been noted. Molybdenite is a common sulfide within the deposit, usually occurring with the best copper mineralization. However, only about 20% of the historic core samples have been analyzed for molybdenite and more studies are necessary to better understand its average grade and distribution.

The deposit is displaced by the gently east-dipping normal fault known as the Bear fault. The fault is defined by strongly sheared dark clay gouge with andesite and sulfide fragments. On the western part of the deposit the mineralization occurs within the foot wall of the fault while to the east the mineralization occurs deeper within the hanging wall.

The Bear projectDeposit is a high priority because of its very large size, historic drilling and potential for higher grades than district averages. Molybdenum could also represent a by-product credit. Exploration to expand and upgrade the historic Bear Deposit resource into a compliant NI 43-101 resource is a high priority.

- 32 -

Acquisition and exploration costs incurred by the Company for the Bear Deposit to December 31, 20142017 were $496,519 (2013$8.51 million (2016 - $340,646) and exploration expenditures were $17,879 (2013 - $12,366) for a total of $514,398 (2013 - $353,012). There were no acquisition or exploration expenditures at the Bear Deposit prior to 2013.

Nieves Silver Project, Mexico

On December 29, 2104, the Company closed the sale of its 50% interest in the Nieves silver property in Zacatecas State, Mexico, to joint-venture partner Blackberry Ventures I, LLC (“Blackberry”), for US$4 million. Under the terms of the agreement, Quaterra will receive four payments over 15 months of US$1 million each, with each payment earning Blackberry an additional 12.5% interest in the project. All costs for maintaining and exploring the property will be the sole responsibility of Blackberry, with no dilution to Quaterra, through the end of 2015 or until Blackberry completes the acquisition, whichever is earlier. Upon closing, Blackberry will become the operator of the Nieves project. In the event that Blackberry subsequently sells the project, Quaterra will receive 5% of the future net sale price. In addition, Quaterra has agreed to transfer its Americas claims in Durango State, Mexico, adjacent to Hecla Mining’s San Sebastian project, to Blackberry.

As at March 26, 2015, the Company owned 37.5% of this project.

Property Description and Acquisition

The Nieves Project is located in the Francisco R. Murguía Municipality of the Zacatecas Mining District near the southeastern boundary of the Sierra Madre Occidental Physiographic Province in central Mexico. The Property is located approximately 150 km northwest of the state capital of Zacatecas and 90 km north of the mining community of Fresnillo. The property consists of 18 concessions covering approximately 12,064.1 ha. The concessions are registered in the name Minera Cerro Gregorio, as of August 5, 2011, a Mexican company wholly owned by Quaterra. The Nieves Property is jointly owned by Quaterra (50%) and Blackberry Ventures 1, LLC. (“Blackberry”) (50%).

Kennecott Exploration Company (“Kennecott”) acquired the Nieves property on January 16th, 1995, through an option agreement with Mexican concessionaires by making specified option payments over five years, and advance minimum royalty payments. On March 13th, 1998, Kennecott transferred its rights under the Nieves option to Western Copper Holdings Ltd. (“Western”) in consideration for an uncapped 2% NSR on certain core concessions and a 1% NSR on others. Western assigned its rights to the Nieves Project to Quaterra on March 26, 1999. The Nieves concessions are subject to a maximum 3% NSR to the original concession holders, which the Company may purchase at any time for US$2 million. Kennecott’s royalties on the property were later sold to Royal Gold Inc. on January 24, 2007.

On April 10th, 2003, Quaterra completed a limited partnership financing with Blackberry Ventures 1, LLC (Blackberry), whereby Blackberry could earn a 50% interest in the Property by funding two exploration programs of US$750,000 each. The initial payment of US$750,000 received in the 2003 Fiscal Year was expended on a 5,300-meter drill program on the Nieves Property. During the 2004 Fiscal Year, Blackberry elected to continue by advancing a further US$750,000 towards a follow-up drill program completed in May 2005, thereby earning a 50% interest in the Property. The partners signed a joint venture agreement in 2006 and have jointly contributed to all exploration costs subsequently incurred.

There are no known significant environmental liabilities related to the current exploration of the Nieves Property. The areas of primary mineral exploration are generally flat-lying, sparsely populated with a few cultivated areas and the remaining land area used for the periodic grazing of livestock. Minimal rehabilitation measures such as stabilizing slopes and planting local flora in areas of disturbance is usually sufficient to satisfy the ecological authorities, the Instituto de Investigaciones Forestales, Agricolas y Pecuarias (“INIFAP”), a government office based in Calera, Zacatecas.

There is little to no surface water for exploration or mining activities but an abundance of ground water exists and the ownership of mineral rights generally allows access to ground water as needed. There are no significant factors or risks that may affect access, title, or the right or ability to perform work on the property. Exploration drilling has been conducted under a permit issued by the Secretaria de Medio Ambiente y Recursos Naturales (SEMARNAT). The permit expired on October 15, 2012, but may be renewed by application.

Since inception to December 31, 2014, the Company had incurred $736,136 (net of recovery) (2013 - $1,754,434) for acquisition costs and $2,009,224 (net of impairment) (2013 - $4,811,803) for exploration expenditures giving a total of $2,745,360 (2013 - $6,566,237) for its interest in Nieves. The Company’s joint venture partner, Blackberry JV had spent, US$7,275,019 (2013 - $7,024,128) including the Company’s administration fee, for its 62.5% interest in Nieves.

Location, Access and Infrastructure

Exploration activities are coordinated from the small town of Nieves (now re-named Francisco R. Murguia) where an office and a house is maintained. Subsequent to the of Quaterra’s 50% share of Nieves to Blackberry as detailed above, Blackberry is responsible for all costs of the office and exploration activities, and is operator of the project. The town of Nieves is accessed via a 17-kilometer paved road from Highway 49. The nearest major population and service centre to Nieves is the mining town of Fresnillo located 90 km to the south. Fresnillo has a population of approximately 75,000 and services the Fresnillo Mine operated by Peñoles. Fresnillo offers a professional work force experienced in mining and related activities in addition to most other supplies and services. International airports are located within approximately a three hour drive of the property in the city of Zacatecas to the south, and in Torreõn (Coahuila State) to the north. Road access is excellent with the main paved highway to Nieves running along the northern portion of the property. A network of dirt roads and trails provide access to the historical mining operations and extend southward to all areas of the property. Drill and access roads can be built easily as most of the Nieves Property is flat-lying with only a few dry creek beds.

The Nieves property lies within the Mexican Altiplano or Mesa Central region. This region is flanked to the west by the Sierra Madre Occidental and to the east by the Sierra Madre Oriental mountain ranges. The Altiplano is dominated by broad alluvium filled plains between rolling to rugged mountain ranges and hills reaching up to 3,000m above mean sea level and average elevations in valleys of approximately 1,700m. Elevations on the Nieves property range from 1,900m. to 2,000m. The terrain is generally flat-lying with a prominent north-south trending ridge along the eastern portion of the property with moderate to vertical slopes. There is very little human habitation on the property, with only a few widely scattered farm houses, although the town of Nieves directly borders the property to the northeast.

The La Quinta field office, as well as core logging, cutting and storage facilities are located on the Nieves Property. Other infrastructure in the area includes: (1) a power line adequate to support a small mill (eg. 100 tonnes per day), (2) a spur of the main Zacatecas rail line that connects the city of Rio Grande, located 18 km to the south, and (3) operating smelters in San Luis Potosi (copper and zinc, approximately 350 km to the south) and in Torreõn, Coahuila state (Peñoles lead-zinc smelter, approximately 200 km north).

History

The first discovery on the area covered by the Nieves Property was the Santa Rita Vein in 1560 by Spanish explorers. Soon after in 1574 the Concordia vein was discovered. The Santa Rita and Concordia-San Gregorio-Dolores veins were the focus of mining by the Spanish and Mexican miners until 1880 when an English company, the Mexican Rosario Mining Company, and two Californian companies, the Almaden Mining Company and the Concordia M. and M. Company, worked in the area. These companies worked primarily on the Concordia vein while a small independent miner Gonzáles Piñera worked concurrently on the San Gregorio vein. Prior to the 1910 revolution, which halted all production in the Nieves District, total ore production in the District was estimated at 50,000 tonnes. The only production reported is from the Concordia Mine where 5,414 tonnes at a grade of 4,065 g/t silver were produced.

Between 1910 and 1978 several companies attempted to de-water, sample, and re-open the historical workings in the Concordia and Santa Rita mines, and were largely unsuccessful. The Santa Rita vein and refurbished mill and flotation plant were purchased by Fomento Minero in 1978; they operated the mine until 1987. Fomento Minero also sank three shafts and deepened a historic shaft along the Concordia-San Gregorio vein system during the 1970’s. The flotation mill was capable of running 100 tonnes/day during this time and was fed 50% tailings and 50% ore with an average head grade of 130 g/t silver, 2% lead, 2.4% zinc and 2.5% antimony, according to Consejo Recursos Minerales. Today, all that remains on the site are the building foundations, abandoned shafts and power lines.

In the early 1990’s, a group of Mexican concessionaires assembled a land position that Kennecott optioned on January 16th, 1995. Exploration work completed by Kennecott included geologic mapping, surface sampling, geophysical surveying and reverse circulation (RC) drilling of the Gregorio North, California and Orion West veins. The drilling intersected several zones of significant silver mineralization hosted by two distinct styles of mineralization. Drill hole NV08 in the California area intercepted two separate 2m intervals of high-grade silver vein mineralization that returned assay values of 367 g/t and 795 g/t silver at depths of 108m and 116m, respectively. In contrast, drill hole NV03 intersected a large low-grade zone of silver mineralization at a depth of 180m depth that averaged 82 g/t silver over 28m. Drill hole NV03 also encountered a high-grade silver vein at 148m depth that returned 254 g/t silver over 2m. Drill hole NV06 also encountered a large zone of low-grade silver mineralization that returned 67 g/t silver over 68m.

After acquiring the Nieves option from Kennecott in 1998, Western Copper drilled 5 RC holes testing the California vein system. The holes were drilled in the area around hole NV08. Western Copper also twinned hole NV08 and reproduced similar assay values for the intercepts reported by Kennecott including 890 g/t silver over 1.0m in drill hole WCNV01. Holes drilled to intercept mineralization below drill hole NV08 returned assay values of 841 g/t silver over 0.45m, 109 g/t silver over 0.8m, and 1,081 g/t silver over 0.35m in drill hole WCNV04.

Systematic drilling began after Quaterra bought the property from Western Copper in 1999. Since Kennecott imitated exploration drilling in 1995, a total of 61,608 meters have been drilled in 205 holes, all but thirteen$7.51 million) of which were completed during the Quaterra/Blackberry earn-in and JV.

Geology

The Nieves Property lies on the western flank of the Central Altiplano in Mexico, just east of the Sierra Madre Occidental ranges. Basement rocks underlying the western Altiplano are a Mesozoic assemblage of marine sedimentary and submarine volcanic rocks belonging to the Guerrero Terrane that sit unconformably on Precambrian continental rocks.

The late Cretaceous to early Tertiary Laramide Orogeny folded and thrust faulted the basement rocks throughout area and preceded the emplacement of mid-Tertiary plutons and related dykes and stocks. Unconformably overlying the Mesozoic basement rocks in the western Altiplano are units from the late Cretaceous to Tertiary, Sierra Madre Occidental magmatic arc. These rocks consist of a “lower volcanic complex” comprising an assemblage of late Cretaceous to Tertiary volcanic, volcaniclastic, conglomerate, and limestone rocks unconformably overlain$7.51 million was funded by a Tertiary “upper volcanic supergroup” of caldera related, rhyolite ash-flow tuffs and flows. Eocene to Oligocene intrusions occur throughout the Altiplano and are related to the later felsic volcanic event. A final stage of NE-SW extensional tectonics accompanied by major strike-slip fault movement during the Miocene developed much of the basin and range topography currently exhibited in the area. Subsequent erosion of the ranges has covered most of the valleys.

The Mesozoic section on the Nieves property is represented by a thick sequence of fine laminar grey to dark green argillite beds up to 1m thick belonging to the late Cretaceous Caracol Formation which is host to silver mineralization on the property. The argillite beds are more abundant to the south in the Santa Rita area and to the west in the Concordia area. The Mesozoic section is isoclinally folded with an axial plane cleavage. Fold axes strike east-northeast to east and beds strike east-west and dip steeply south to near vertical.

Tertiary clastic rocks unconformably overlie the Caracol Formation on the east side of the Nieves Property. The shallow dipping Tertiary clastic section includes a 1 to 10 meter thick conglomerate composed of rounded to sub-rounded limestone boulders in a sandstone groundmass. Above the limestone conglomerate there is up to 130m of conglomeratic sandstone with thin bands of calcareous conglomerate. Overlying the conglomerate is 40 meter to 50 meter of Tertiary volcanic rocks composed of rhyodacitic to andesitic welded tuff. A thin 1.5 to 2 meter unit of grey to dark grey basalt occurs above the tuff and is in turn overlain by at least 56m of porphyritic rhyolite flows striking north-northwest and dipping northeast. These flows underlie a prominent north trending ridge on the east side of the Nieves property and are the host rock for manganese-calcite veins and breccia mineralization previously exploited by local miners.

The oldest structures on the Nieves Property are the folds which affect the Mesozoic argillite beds. These structures are likely related to compression during the Laramide Orogeny in the Cretaceous. Thrust faults are also common features of structures attributed to the Laramide Orogeny and several have been suspected to occur on the Nieves Property. Post-Laramide structures affected both the Mesozoic Caracol Formation sedimentary rocks and the Tertiary volcanic and sedimentary rocks. These structures include: (1) faults that strike 330º to 000º and dip moderately northeast to east with east plunging slicken-sides, (2) faults that strike 170º to 180º and dip steeply to the west, and (3) major vein structures that strike 240º to 270º and dip 60º to 90º to the south.

Mineralization

Silver mineralization on the Nieves Property is classified as low-sulphidation epithermal mineralization and is the primary exploration target. Epithermal silver veins are the dominant type of deposit within the Altiplano Region of Mexico that includes world-class examples such as Pachuca, Zacatecas, Fresnillo, and Guanajuato. The closest example is the Fresnillo deposit, located 90 km to the south of the Nieves Property. The Fresnillo deposit includes mantos and chimneys, stockworks, disseminated mineralization, and veins that show vertical mineralogical zonation. Typically in these veins, the high-grade silver (gold) zone is constrained in elevation within the vein structure to up to 500 meters vertically, or between 180 meters and 750 meters depths below which the veins becomes dominated by base-metal sulfides and progressively lower in precious metal content.

The most economically significant mineralization at Nieves occurs in anastomosing carbonate-quartz-sulphide vein systems and stockworks that have been defined over a total strike length of 3.8 kilometers by 54,814 meters of drilling in 187 holes. The system develops to a maximum true width of in excess of 200 meters and has a proven down dip extent of approximately 525 meters.

The carbonate-quartz-sulphide veins contain the best grades of silver, gold, lead and zinc. They consist of calcite that is partially to totally replaced by grey to white, chalcedonic, fine-grained quartz veins and veinlets. Individual veins are from centimetres to 1.5 meters wide with up to 50% sulphide minerals. Sulphides include pyrite, stibnite, sphalerite, galena, chalcopyrite and the silver sulphosalt freibergite, as well as minor proustite, pyrargyrite, and jamesonite.

The central and most important of the three vein systems is the Concordia-San Gregorio-Dolores system which includes both the La Quinta and Gregorio North zones. Mineralization along the Concordia-San Gregorio-Dolores vein has a known total strike length of 1,300 meters and a true width up to 100 meters. The mineralized zone in the Gregorio North area is approximately 1,200 meters long and up to 200 meters wide. The La Quinta and Gregorio North zones are the subject of the August 9, 2012 Caracle Creek 43-101 compliant resource estimate but only the La Quinta zone is included in a proposed open pit as shown in the October 31, 2012 preliminary economic assessment.

The attitude and size of the mineralized zones along the Santa Rita zone to the south and California vein system to the north are not well understood at this stage of exploration. Drilling along the Santa Rita system suggests that the mineralized zone is at least 750 meters long and may be up to 340 meters wide. The mineralized zone along the California vein system is at least 550 meters long and may be up to 130 meters wide.

Recent drilling has expanded the size of mineralized zones along all vein systems and additional drilling may significantly enhance the resources and economics of the project. Many of the vein systems are open along strike and all remain open to depth. Because some zones could be terminated along strike by late vertical fault structures, the discovery of strike extensions to the Nieves vein systems will only require continued drilling guided by the promising results of surface geophysical surveys.Freeport Nevada.

Exploration and Drilling Results

Exploration between 2003On August 13, 2015, the Company commenced a five to seven-hole exploration drilling program at the Bear Deposit funded by Freeport Nevada. The drilling program was designed to assess historic assay results and 2010determine geological controls for higher-grade mineralization. A magneto telluric (MT) geophysical survey was also carried out over the Bear Deposit target area to assist in the drill site selection. Assays from the three holes completed in 2015 were released sequentially on November 17, December 23, 2015 and February 8, 2016. (Please see press releases at www.quaterra.com issued on those dates for details).

Highlights fromHole B-048 include an intercept of 1,157.5 feet of 0.42% copper containing 123.6 feet of higher grade mineralization beginning at 2,588.5 feet averaging 1.07% copper, 0.03% molybdenum, 0.036ppm gold, and 0.9ppm silver.Hole B-049, drilled vertically to a depth of 3,635 feet, intercepted 1,138 feet (407.9 meters) of 0.26% copper beginning at a depth of 1,588 feet. Higher-grade mineralization, although present, is restricted to narrow zones varying from 3.0 to 5.5 feet in width. This hole extends an already large mineralized system an additional 770 feet to the north.Hole B-050, drilled vertically to a depth of 3,838 feet, intercepted 521.9 feet (159.1 meters) of 0.36% copper beginning at a depth of 2,429.2 feet. Included within this interval is 279.3 feet (85.1 meters) of 0.44% copper starting at 2,491.4 feet. A 6.1 -foot (1.9 -meter) interval of massive pyrite-magnetite-chalcopyrite skarn starting at 2,330.5 feet averages 1.91% copper, 0.22 ppm gold and 5.7 ppm silver.

Three additional holes were drilled in 2016, and results were released on April 6, 2016, May 24, 2016, and June 9, 2016. (Please see press releases at www.quaterra.com issued on those dates for details).

Hole B-051, drilled vertically to a depth of 3,878 feet, intercepted 1,483.3 feet (452.1 meters) of 0.26% copper beginning at a depth of 2,191.2 feet. Included within this interval is 1,213.8 feet (370.0 meters) of 0.30% copper starting at 2,191.2 feet. Several narrower intervals contain > 0.40% copper with anomalous gold and molybdenum. Hole B-051 is a significant step-out. The nearest holes are B-049, approximately 1,150 feet to the west and historic hole B-22, about 1,300 feet to the southwest.

The thickness of the mineralized intercept in B-051 is larger than those in the three previous holes of the drilling program. Bornite also is more common than in previous SPS holes, occurring with chalcopyrite and molybdenite in quartz-sulfide veins, veinlet swarms and stockworks. The quartz-sulfide veins appear to correlate with higher gold and molybdenum values found in B-051 compared to the three previous drill holes. The interval 3,253 to 3278 feet averaged 0.43% copper, 182 ppm molybdenum and 0.12 ppm gold over 25 feet; the interval 2,218 to 2,241.9 feet averaged 445 ppm molybdenum over 23.9 feet.

Hole B-052, drilled vertically to a depth of 3,468 feet, intercepted two zones of 0.4% copper, the first of 43 feet (13.1 meters) with 201 ppm molybdenum starting at 2,508 feet and another of 29 feet (8.8 meters) starting at 2,667 feet. Overall, the hole intercepted 666.2 feet (203.1 meters) of 0.14% copper mineralization beginning at a depth of 2,081.3 feet.

The lower copper and gold grades, combined with a higher pyrite/chalcopyrite ratio, indicate that hole B-052 was drilled in a more distal part of the system. Additional drilling will be necessary to test this concept as Bear mineralization remains open in three directions.

Hole GHH-001, the sixth and final drill-hole of the program, is located in Ground Hog Hills about 6,000 feet south of previous SPS holes. It was drilled vertically to a depth of 2,017.5 feet and cased for possible future deepening. Sporadic zones of copper mineralization were intersected which are interpreted as an extension of Bear mineralization to the north.

The entire six-hole exploration drilling program, which commenced in August 2015, totaled 20,274.5 feet. The five holes at Bear, including twin hole B-048, totaled 18,257 feet. Results from Hole B-048 supported historic assays from Hole 23B drilled in 1966 by QuaterraAnaconda. Drilling results from holes B-049 to B-052 were successful in extending the Bear mineralization an additional 2,000 feet north-northeast by 3,000 feet northwest-southeast, with the average mineralized intercept in these four step-out holes averaging approximately 1,000 feet in thickness. The Bear system remains open in three directions. Copper mineralization is overlain by ubiquitous propylitic alteration with moderate to strong phyllic alteration, often laced with tourmaline veining and Blackberry included air photograph interpretation, surface sampling, geologic mapping,flooding. Significantly higher grades, if present, will most likely be found where quartz monzonite is cut by quartz monzonite porphyry dikes as occurs at the nearby Yerington mine. The Bear porphyry copper deposit currently covers more than two geophysical surveys, six drill programssquare miles.

Quality assurance and control

Core samples were either sawed or split by SPS personnel in Yerington, Nevada, and shipped to Bureau Veritas Minerals NA – Inspectorate America Corporation (“Bureau Veritas”), an ISO certified assaying/geochemistry facility, in Reno, Nevada for sample preparation. Gold analyses are assayed in Bureau Veritas’ lab in Reno using their “FA430” procedure (fire assay with atomic absorption finish) with a 5 ppb Au detection limit. Prepared pulps are shipped to Bureau Veritas’ lab in Vancouver, B.C., Canada, for analysis using their “MA 300” procedure for 35 element ICP-ES analysis. Commercially prepared standards and blanks are inserted by SPS at 50-foot intervals to insure precision of results as a quality control measure. SPS has a chain of custody program to ensure sample security during all stages of sample collection, cutting, shipping, and storage.

d.Groundhog copper project, Alaska

The Groundhog copper project is a 40,000-acre property situated in an established copper porphyry belt situated 200 miles southwest of Anchorage, Alaska. It is located on State of Alaska claims covering the northern extension of a 10-kilometer wide north-northeast trending structural zone that hosts a number of porphyry copper-gold prospects, including the large Pebble porphyry copper, gold and molybdenum project, which is approximately three 43-101 independent technical reports, twomiles south of which include 43-101 compliant resource estimates, all prepared by Caracle Creek International Consulting Inc.the Groundhog claim boundary.

Acquisition and Staking of Toronto, Ontario (“Caracle Creek”).Claims

In April 2011,2017, Quaterra contracted Mira Geosciencesigned a lease agreement with Chuchuna Minerals Company (“Chuchuna”), an Alaska corporation, giving Quaterra an option to invert ground magnetic data frompurchase a 90% interest in the Nieves Property. The results indicated that the geophysics model was poorly constrained dueGroundhog copper prospect. Quaterra committed to insufficient data particularly along the western edge of the magnetic low anomaly. In December 2011, Zonge International (Zonge) was contracted to conduct additional ground magnetometer surveying along 14 N-S lines with a spacing of 200m between lines. The survey extended the magnetic low an additional 1200 meters westfunding $1 million for a total E-W length of 2200m.

In June and July 2011, Zonge conducted IPR surveys along nine lines that indicated that several of the vein systems including the Santa Rita, Dolores, Nino and Orion veins extended to the western edge of the existing survey coverage. The coverage was extendedexploration in the first quarter of 2012, with a survey consisting of six lines totalling 28.4 line-kilometers, of vector CSAMT and CSIP and nine follow-up lines of pole-dipole IPR totalling 16.5 line-kilometers. The six lines of vector CSAMT/CSIP were spaced 400 meters apart and covered 1,000 hectares westyear of the main veinsagreement, and a minimum of $500,000 in each of the following four years. Quaterra can earn its 90% interest in Groundhog by providing a total of $5 million in funding for exploration over five years, and by paying Chuchuna a lump sum of $3 million by the end of the fifth year. Quaterra has no obligation to exercise its option and can terminate the agreement at its discretion annually. Chuchuna will be the operator of the project and will plan, implement and manage exploration field programs as set out in a budget and work plan approved by Quaterra.

If Quaterra exercises its option to acquire 90% of Groundhog, Chuchuna and Quaterra will enter into a joint venture agreement. Chuchuna will retain a 10% interest in the areaproperty carried to production, and a net smelter returns (NSR) royalty of 1.75% . Within the first ten years Quaterra may purchase 50% of the enigmatic magnetic low.NSR royalty by paying Chuchuna $25 million.

- 36 -Location and Access

The geophysical anomalies were followed up by surface mapping and sampling. The most interesting area identified to date is West Santa Rita, where the mapping identified two groups of narrow, sub-parallel two to 30 centimeters wide calcite-quartz veinlets, some of which contain strong gold and silver mineralization. Gold values range from nil to 8.11 g/t over 0.2 meters and silver values range from nil up to 253 g/t over 0.4 meters. Outcrop in the area is sparse but at least one sample from a fault zone coinciding with the anomalous IP zone defining the Nino vein is anomalous in gold and silver.

Quaterra and Blackberry completed two more phases of drilling (VII and VIII) between March 2010 and October 2011, consisting of 73 drill holes and totalling 18,547 meters. Most of the drilling concentrated on the Concordia-Dolores-San Gregorio vein system, but significant amount of drillingproperty is located in the CaliforniaBristol Bay region of southwest Alaska, 300 km (186 mi) southwest of Anchorage within the Lake and Santa Rita vein systems as well.

The drill program was successful at increasing the size of known mineralized zones along all the major vein systems. Mineralization along the Concordia vein system was extended an additional 400 meters, to a total of approximately 1,300 meters. The length of known mineralization along the California vein system was increased to a total of approximately 550 meters and it remains open to the east. Phase VII and VIII drill programs were successful in doubling the strike length of the Gregorio North mineralized zone locatedPeninsula Borough. It lies 27 km (16 mi) north of the San Gregorio vein, extending the strike lengthvillage of Iliamna and 10km (6 mi) west of the mineralized zonevillage of Nondalton. The southern portion of the claim group is accessible by ATV but the majority of the property is best accessed by helicopter. The general location of the Groundhog property is provided on the following map.

Property Status

The Groundhog property currently consists of 283 State of Alaska 160-acre claims (45,280 acres 18,324 ha) immediately to approximately 1200 meters. A totalthe northeast (3 miles) of 15 drill holes systematically tested the Santa Rita veinPebble porphyry copper-gold deposit. The claims lie within a 78,240-acre prospective area of interest.

History

During the 1980s and 1990s COMINCO explored the area north of Iliamna Lake and discovered several porphyry copper and epithermal gold prospects. Northern Dynasty Minerals Ltd. acquired the COMINCO properties in the early 2000s and began an aggressive exploration program that resulted in the discovery of the large and high-grade Pebble East Cu-Au-Mo deposit in 2006. By 2004 Liberty Star, Full Metal Minerals and Alaska Earth Sciences had become active in the area and over 1,000 state claims were staked.

The Groundhog property was staked by Alaska Earth Sciences Inc. (“AES”) in late 2004 and early 2005 consisting of 489 160-acre claims for Greg Ellis, a private investor. Kennecott Exploration (a subsidiary of RioTinto) optioned the Groundhog property from 2009 to 2013 from AES. Kijik Corporation (an Alaskan native corporation) and AES formed Chuchuna Minerals Co. (“Chuchuna”) which created a joint venture to explore the Groundhog property in 2016. In April 2017, Quaterra entered into an agreement with Chuchuna to acquire 90% interest in the Groundhog project.

Regional Geology

The Groundhog property is located in the Kahiltna Terrane near the northeast trending, crustal-scale Lake Clark fault system over 500 meters along strike,that separates the Kahiltna Terrane to the northwest and the total length of mineralization was extended to approximately 750 m and remains openPeninsular Terrane to the west.southeast. The Kahiltna is characterized by a Jurassic-Cretaceous flysch sequence of andesitic turbidites deposited in a basinal setting. Tectonic activity since the Cretaceous has been controlled by a compressional system due to northwest dipping subduction of the Pacific plate below the North American plate. The flysch sequence is intruded by various Cretaceous and early Tertiary plutons such as the nearby Kaskanak batholiths and the multi-phased intrusive corridor and is uncomfortably overlain by Tertiary volcanics and sediments. Displacements along major dextral strike-slip and thrust faults within the Lake Clark fault system have accommodated most of the compressional stress. Late northeast and northwest-striking Tertiary normal and graben faults are common on the property. The area has been glaciated with a variety glacial-fluvio deposits present in many areas.

34

In the Pebble and Groundhog area the older basement units are gently folded Jurassic-Cretaceous andesitic argillite, siltstone, graywacke with some diorite and gabbro sills. A variety of Cretaceous intrusions occur in a northeast trending structural corridor which extends onto the Groundhog property. Older intrusions (98-96Ma) have an alkali affinity and are comprised of biotite pyroxenite, monzosyenite, and monzonite. Subalkalic granodiorite intrusions (91-89 Ma) include the Kaskanak Batholith which is genetically related to the Cu-Au-Mo mineralization at Pebble.

Property Geology

Geologic mapping and geochemical sampling of the Groundhog claim block has been completed by AES geologists in 2005-2007, KEX geologists 2010-2012, and AES geologists in 2017. A variety of geophysical surveys were completed in 2006, 2007, 2010, 2011, and 2017 by various geophysical contractors.

Jura-Cretaceous Meta-Sedimentary and Intrusive Rocks

The oldest unit exposed on the property is the Kahiltna flysch, a meta-sedimentary basement flysch sequence of fine-grained, thinly-bedded siltstone, mudstone and massive greywacke. The sediments are regionally metamorphosed from greenschist to low amphibolite facies with some contact metamorphism near mafic intrusions. Some andesitic flows are interbedded with the sediments which are andesitic in composition. The Kahiltna flysch is intruded by some intermediate to mafic intrusive bodies a few kilometers in length. These intermediate to mafic bodies are mainly composed of fine- to medium-grained gabbro with subordinate pyroxenite and diorite-granodiorite.

Three main strongly magnetic bodies from south to north on the Groundhog property are the Alpha, Beta, and Gamma anomalies. The Alpha anomaly is a late Jurassic (U-Pb date 149.2 Ma) medium-grained banded ophitic gabbro. The Beta anomaly is a Late Cretaceous (U-Pb date 98.2 Ma) medium-grained biotite granodiorite. The Gamma anomaly is a very poorly exposed fine-grained magnetite-rich massive gabbro of unknown age.

Quartz-feldspar veinlets containing pyrite and traces of chalcopyrite along with locally abundant epidote-carbonate-pyrite veinlets are found at several locations at the Alpha and Beta anomalies.

Tertiary Volcanics

Tertiary volcanic rocks are the most common and best intersections include 149 g/t Agexposed units on the property and 0.11 g/t Au over 31.25 m, which includes 6320 g/t Agoccupy the higher elevation areas encompassing most of Groundhog Mountain. It consists of a post-mineral sequence of volcanic flows and 1.82 g/t Au over 0.25 meters in drill hole QTA123 alongtuffaceous beds of various compositions that can be subdivided into intermediate volcanic rocks, intermediate tuffaceous rocks, mafic volcanic rocks, rhyolite tuff and volcanic breccias. A medium- to fine-grained light-colored diorite is present extending northeast from Groundhog Mountain.

Structural Setting

Deformation on the Concordia West vein, 104 g/t Ag over 19 meteres, including 6410 g/t Ag over 0.1 meters and 5960 g/t over 0.1 meters in drill hole QTA137 alongGroundhog property is dominated by late brittle faults that cut the California vein, and 152.2 g/t Ag and 0.12 g/t Au over 57 meters in drill hole QTA144Tertiary volcanics. The Jura-Cretaceous sedimentary package is regionally known to be affected by broad open folding. The basement sediments generally dip north 60-70 degrees, but dip to the south 35-60 degrees in the Concordia West area.vicinity of the Alpha anomaly. The Tertiary stratigraphy well exposed on Groundhog Mountain is upright and tilted about 10 degrees to the south-southwest.

Most faults on the property have been interpreted from airborne magnetic data acquired in 2010. Two major sets of faults have been interpreted, one striking northeast and the other striking west-northwest. The northwest structures appear to be cut by the northeast faults. Extending major faults from the Pebble property combined with IP data observations, the northeast faults appear to be southeast dipping normal faults. Fault breccias have been observed in Groundhog Mountain Tertiary volcanics.

Exploration and Drilling Results

The resultsobjectives of the 2017 reconnaissance drilling program were to determine the subjectsource of a fourth technical reportnumerous IP anomalies identified by historic and 2017 surveys and to confirm the third NI 43-101 compliant independent resource estimate prepared for the Nieves project by Caracle Creek titled “Nieves Project From 43-101 Technical Report Preliminary Economic Assessment Zacatecas, Mexico” and dated October 31, 2012. The most recent estimate, dated August 9, 2012, was incorporated into the October 31, 2012 preliminary economic assessment (“PEA”) for the Nieves project by M3 Engineering & Technology Corp. (“M3”) of Tucson, Arizona.

During preparationprospectiveness of the PEA, Quaterra tested the strike extension of mineralization at Nieves with eightarea for porphyry copper mineralization. Four widely-spaced core holes totaling 3,060 meters. Hole QTA 190 was collared4,073 feet – the first ever drilled on the property – were drilled to test an induced polarization (IP) anomalyanomalies over an area approximately six miles north-south by three miles east-west.

The holes targeted only the southernmost of three magnetic anomalies that have been defined on the Orion vein,property by historic surveys and 26.1 kilometers of new IP completed by Zonge International in June and July this year:

Drill results confirm that pyrite is the source of all IP anomalies tested and will be an effective tool for exploring the project’s large land position; and that intrusive rocks similar to those at Pebble were intersected in Holes 3 and 4 and extend well into the Groundhog land block. IP surveying to date has defined a two-kilometer westward extension of the Gregorio vein. The hole intersected 0.8 meters of 1,865 grams per tonne (g/t) silver (54.5 oz/ton) which is part of a larger vein interval starting at 243.6 meters averaging 341 g/t silver (10.0 oz/ton). Holes QTA 191 and QTA 192, drilled 200 meters west and east of QTA 190, intersected 0.85 meters of 289 g/t silver and 1.1 meters of 284 g/t silver respectively. The new zone islarge sulfide anomaly(s) open laterally and at depth.depth whose ultimate extent and source will be determined by additional surveys and deeper drilling. Data compilation and analysis will be completed prior to finalizing 2018 work plans.

Three holes (QTA 185-187) tested coincident IP and geochemical gold anomalies on the western extension of the Santa Rita vein. Holes QTA 186 and QTA 187 intersected 5.1 -meter intervals averaging 0.7 g/t gold and 0.55 g/t gold respectively. The gold anomalies may represent the upper levels of deeper and as yet undiscovered silver mineralization.

Wildcat holes QTA 188 and QTA 189, drilled two kilometers further west from holes QTA 185-187 to test anomalous vein occurrences, did not intersect significant mineralization.

Sampling, Analysis and Security of Samples

Quaterra and Blackberry have drilled 192 holes on the Nieves property. All but 10 holes completed by Quaterra in 1999-2000 were core holes. Major Drilling of Mexico S.A. de C.V. was the drill contractor for drill programs completed during 1999 to 2006 and B.D.W. International Drilling of Mexico S.A. de C.V. has been the drilling contractor since 2006.

Drill hole orientations are generally perpendicular to the strike of the overall structural trend of the vein(s) targeted. HQ (63.5 mm) was the standard drill core diameter. NQ (47.6 mm) was used locally as an extension (a tail) where drill conditions were difficult. Drill hole locations are surveyed using a RTK Trimble (model R8), double frequency GPS with precision to 1 cm. Down-hole survey readings were recorded on average approximately every 50 or 100m depending on the length of the hole using an Eastman Single Shot instrument. Survey results have been corrected for magnetic declination (+9º).

Core samples were collected from the drill site and brought to the core storage facility on the Nieves Property for logging and sampling by the project or assistant geologists on a daily basis. The drill core is washed and core recovery estimated. Rock types, alteration minerals, textural and structural features, veining, and mineralized zones are documented. Sample intervals are measured, marked with permanent marker, and given a sample number and sample tag by the geologists. From this point, technicians core saw the core into halves where one half of each interval is placed with the sample tag into a sample bag and marked with the sample number. The other half is placed back into the core box in its original position and the core boxes are then stacked on racks and stored in order and by hole number in their core storage facility. Where the veins are coherent they are sawed in half perpendicular to the “grain” to get a representative split. Samples are placed into individualand sealed in heavy plastic bags marked withinto two- to three-meter samples by AES personnel. The samples were then sealed into two foot by three foot rice bags and shipped by a uniquecommercial air carrier from Nondalton, Alaska, to Anchorage, Alaska. In Anchorage the samples were picked up by AES personnel who then inserted sample identification number and withblanks from a sample tag placed into the bag. Sample ID numbers and meterages are also written on the core trays.

Samples arelocal rock quarry approximately every tenth sample. The samples were then packaged into sealed sacks and takenshipped by Quaterra employees to ALS Chemex Laboratories in Guadalajara for preparation. No employees, officers, directors or associates of Quaterra or Blackberry JV are involved in the preparation of the samples.

Standard and blank samples are also included with the primary core samples for analysis. Standards are inserted directly into the sample sequence with a frequency of ~ 1 in 50. Blanks are inserted directly into the sample sequence with a frequency of ~ 1 in 25. The final prepared samples are shippedLynden Transport trucks to the ALS laboratoryUSA’s Prep Laboratory in Vancouver, Canada for analysis. AllFairbanks, Alaska, where they were crushed, pulverized and split. ALS then shipped a split of the samples to their Reno Nevada analytical lab where they were analyzed using a 41 element ICP method (ME-ICP41), in addition to analyzing goldby ME-MS41 ultra trace Aqua Regia ICP-MS and silver by standardAu-AA23 (Au 30g fire assay (ME-GRA21)with AA finish, 0.005 ppm Au detection limit). Lead and zinc values over 10,000 ppm and silver values over 100 ppm were re-assayed by atomic-absorption methods (ME-OG62). The Company is unaware of any known drilling, sampling or recovery factors that could materially impact the accuracy and reliability of the results. The Company believes the sampling procedure is appropriate for the type of mineralization being assayed such thatALS routinely inserts about 15 duplicate samples, are representative and there is no sampling bias.

ALS Chemex is an ISO 9001:2008, ISO 17025:2005 and Standard Council of Canada accredited laboratory with preparation and analytical laboratories operating in over 16 countries. Samples are sent to ALS Chemex in Guadalajara for preparation using their PREP-32 procedure. Upon receipt samples are dried, weighed and crushed. Two hundred and fifty grams of material is split and pulverized to at least 85% passing 75 microns. Reject material is retained at ALS Chemex in Guadalajara.

Samples were analyzed using fire assay – gravimetric finish method in addition to ICP. Silver was analyzed with two methods including aqua regia digest and a combination of ICP-AES (Inductively Coupled Plasma – Atomic Emission Spectroscopy) finish and fire assay and gravimetric finish. Gold was analyzed with fire assay and gravimetric finish. The rest of the elements were analyzed with aqua regia digestion and ICP-AES finish. In the aqua regia digest and ICP-AES finish, the samples are digested in aqua regia in a graphite heating block. After cooling, the solution is diluted to 12.5 ml with deionized water, mixed and analyzed by ICP-AES. The results are corrected for inter-element spectral interferences. In the fire assay and gravimetric finish, the samples are decomposed with fire assay fusion, during which the sample is fused with a mixture of lead oxide, sodium carbonate, borax, silica and other reagents to produce a lead button, which is cupelled to remove the lead. The remaining gold and silver bead is separated in dilute nitric acid, annealed and weighed as gold. Silver is determined by the difference in weights.

Futures plans

Previous geologic, geochemical, and geophysical studies conducted on the sample sequences were not utilizedproperty by Quaterraa major international mining company, have identified a number of large, high priority, magnetic and Blackberry JV during initial phases of exploration. Routine analysis of standard reference material (standards) began in 2007 with the insertion of a commercially prepared standard. Duplicate sampling began in 2008, and continued through the 2011 drill program. Duplicate samples were packaged and shipped using the same security protocols as the primary drill core samples and submitted to Skyline Assayers & Laboratories (“Skyline”) in Tucson, Arizona. Skyline is ISO 17025 accredited including analyses for Au and Ag by fire assay (including gravimetric methods), whichinduced polarization (IP) targets. It is the method of analyses used for the submitted samples.

A review of the Nieves data in the October 16, 2012 M3 technical report concluded that the data quality is adequate at this stage of the projectintention to evaluate these, and can be used in 3D modelling for the purpose of resource estimation. The quality control review indicates that there were no major problems in the core shack such as sample mix ups or contamination. The slightly high failure rate of core duplicates is probably an indication of the nature of the ore that is characterizedother targets identified by narrow veinlets.

The failure rates of external standard (KM2653) are high for silver, but this is due to the different analytical methodmore recent work by Chuchuna, by mapping, sampling, additional IP and not the poor quality of the data, which is suggested by the performance of the laboratory standards. Also, silver analyzed with the ME-ICP41 method is slightly biased high and silver analyzed with the ME-GRA21 method is slightly biased low, but these biases are not always consistent with the laboratory standard, suggesting that the problem is with the external standard. In the previous phases silver was analyzed with the same methods and a commercially available certified standard (CDN-SE-1) was used and performed well for silver. Recommendations for future programs include the use of an external standard with a similar certified value as the silver grades at Nieves that is certified for the same analytical method and has similar matrix.

The average gold value in phases at Nieves is 0.058 g/t including all data and 0.22 g/t including only data above the detection limit. The quality of the Au assay data is considered adequate to include Au in the resource calculation at this stage of the project, especially because the grade of Au is fairly low and it is not the main commodity at Nieves. Also, Au analyzed with ICP-OES and gravimetric method is comparable. Recommendations for future programs include using fire assay and instrument finish (AAS or ICP) for Au assays and that a certified standard with a low grade value, same analytical method and similar matrix is inserted and that the frequency of the quality control samples be increased to include one standard, one blank and one core duplicate with every twenty samples.

Metallurgical Testing

Preliminary metallurgical testwork on the composite sample from the Nieves property was completed in June 2010 by G & T Metallurgical Services Ltd. Approximately 100 kg of coarse crush material was composited from reject core material from selected intervals in 12 holes drilled through the La Quinta mineralization in 2009-2010. The sample was determined to contain ~ 79 g/t Ag (theoretical grade of 83 g/t Ag). Freibergite was the major silver phase present in the sample. Ore hardness tests indicated that the sample was moderately soft with a Bond work index of 10.8 kWh/tonne. Open circuit floatation tests showed that ~ 86% of the Ag can be recovered into a final concentrate with a grade of ~ 2.3 kg/tonnes Ag. Rougher tests suggested that Ag recovery was relatively independent of primary grind size between 67 and 104µm K80. Additional testwork was recommended to investigate coarser primary grind sizes. Rougher tests also indicated that silver recovery could also be increased by using a collector such as EROPHINE 3418A which would increase the selectivity of Ag over pyrite. Open circuit cleaner tests suggest that regrinding the rougher concentrate to 20µm K80 had no significant benefit on silver metallurgy. However, increasing the pH of the cleaner circuit to 10 significantly improved the Ag grade in the final concentrate. For the purposes of the preliminary economic assessment, design parameters of 86% silver recovery with a final concentrate grade of 2,300 g/t were used.

Mineral Resource Estimate

Caracle Creek completed an updated NI43-101 independent mineral resource estimate for the Nieves project in June 2012. A summary of the resource estimate within the Concordia and San Gregorio vein systems using a reporting cut-off grade of 15 g/t Ag is shown below:

1 Reported at a cut-off grade of 15 g/t Ag. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
2 Tonnes have been rounded to the nearest 10,000.
3 Ag grade has been rounded to one (1) significant digit.

- 39 -

4 Au grade has been rounded to two (2) significant digits.
5 Ounces have been rounded to nearest 100. One (1) troy ounce = 31.103 grams.

The mineral resource is based on drilling information as of June 22, 2012. The database includes collars, assays, survey and lithology information from 8 drill holes from programs of previous operators between 1995 and 1996, 10 drill holes drilled by Quaterra between 1999 and 2000, as well as 174 drill holes drilled by Quaterra and Blackberry between 2004 and 2012. The estimation used geostatistical block modeling methods constrained by a mineralised wireframe. GEMCOM’s GEMS resource modeling software V.6.3 was used to generate the block model and perform the grade estimation. Grades for Ag & Au were estimated using the inverse distance method of interpolation. The mineral resources were classified according to the CIM Standard Definition for Mineral Resources and Mineral Reserves (December 2005) guidelines and reported in accordance with the Canadian Securities Administrators National Instrument 43-101.

The mineralized domains were constructed primarily from the Ag grade assay data. The La Quinta mineralized domain was defined using 99 drill holes and 5072 samples. The Gregorio North mineralized domain was defined using 25 drill holes and 1729 samples. The drill holes were drilled in a sectional pattern with a drill hole spacing ranging from 20 - 100 meters, in the La Quinta area, and 20 - 175 meters in the Gregorio North area. The mineralized domain was projected 100 meters beyond the last drill hole. Due to the potential for bulk open pit mining, a grade cut-off was not used when constructing the mineralized domain. However, if the last assay in the interval was less than 0.1 g/t Au, then it was not included in the mineralized domain unless it had a significant Ag grade component of 10 g/t Ag. The estimation parameters set for the mineral resources were not allowed to interpolate through un-sampled intervals. An Ag value of 0.1 g/t (Half Detection Limit) was assigned to the missing intervals.

The Qualified Person responsible for the updated Nieves project resource estimate is Jason Baker, P. Eng., of Caracle Creek. Zsuzsanna Magyarosi Ph.D., also of Caracle Creek, is the Qualified Person responsible for the QA/QC evaluation. Doris M. Fox M.Sc., P. Geo,, also of Caracle Creek, is the Qualified Person responsible for the site visit and sampling procedures.

Preliminary Economic Assessment

M3 Engineering & Technology Corp. (“M3”) of Tucson, Arizona used the Caracle Creek mineral resource estimate to complete a preliminary economic assessment (“PEA”) for the Nieves project October 31, 2012 and titled “Nieves Project Form 43-101 Technical Report Preliminary Economic Assessment Zacatecas, Mexico”. The PEA was amended and restated on January 7, 2014 in a document titled “Nieves Project Form 43-101 Technical Report Preliminary Economic Assessment Zacatecas, Mexico”. The study concluded that the project has potential for development as an open pit silver mine that would produce 55.5 million ounces of silver over 10-year mine life.

A PEA should not be considered to be a pre-feasibility or feasibility study as the economics and technical viability of the Project have not been demonstrated at this time. Mineral resources that are not mineral reserves do not have demonstrated economic viability. A PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too geologically speculative at this time to have economic considerations applied to them to be categorized as Mineral Reserves. Thus, there is no certainty that the production profile concluded in the PEA will be realized. Actual results may vary, perhaps materially.

The PEA set out the following key project parameters:

- 40 -

The mine plan for the Nieves project is an open pit that straddles the Concordia vein and includes three pit phases. A 35.4 -million tonne mineralized zone would be mined at a rate of 10,000 tonnes per day resulting in a 10-year mine life and at a 5.4:1 (waste to ore) strip ratio. The pit includes 28.3 million tonnes of higher grade material averaging 65 g/t silver and 0.045 g/t gold (at a cutoff of 30.5 g/t silver); and 7.1 million tonnes of lower grade material averaging 24 g/t silver (at a cutoff of 21.3 g/t silver). The San Gregorio zone was not included in the mine plan but may become viable with additional drilling.

The financial analysis is based on a silver price of $27 per ounce and a gold price of $1,300 per ounce, rounded numbers which are both less than the SEC-recommended three-year historical price through the end of August. The analysis includes deductions for all royalty payments and a contingency of 20%. No credits are assumed for lead or zinc. Sensitivities were run for the price of silver, operating cost and initial capital cost.

The Qualified Person for the preliminary economic assessment is Joshua Snider P.E. with M3 Engineering & Technology Corp., Tucson, Arizona. The Qualified Person for the mining portion of the PEA is Jeffery Choquette P.E. of Butte, Montana, and for metallurgy Thomas L. Drielick P.E. M3 Engineering & Technology Corp., Tucson, Arizona.

The PEA emphasizes that additional exploration and drilling could both expand the current pit and upgrade the San Gregorio inferred resource which was not included in this study. The San Gregorio inferred resource includes 16.3 million ounces of silver and 48,300 ounces of gold using a cutoff of 15 grams. Vein systems to the north and south of the pit also have potential for additional resources.

Herbert Gold Project, Alaska

The Herbert gold project is an early stage, partially drill-tested, high-grade, gold mineralized mesothermal quartz vein system in the historic Juneau Gold Belt of southeast Alaska. The project consists of 91 unpatented lode claims located 30 kilometers north of Juneau and 42 kilometers south of Coeur Alaska's new Kensington gold mine. The property covers six parallel vein structures exposed at the toe of a retreating glacier.

Mineralization consists of mesothermal quartz-carbonate-gold-base metal veins similar to those in other historic mines in the district. Four principal veins have been identified, which from south to north include the Floyd, Deep Trench, Main, and Goat veins. Minor veins include the North, Ridge and Lake veins. The principal veins strike N80E and dip steeply to the north. The cumulative strike length of all mapped veins at present is over 3,700 meters.

Quaterra (35%) and Grande Portage (65%) formed joint venture for the further exploration and development of the property with each party bearing its proportionate share of costs. Grande Portage is the operator of the Herbert gold project.

A total of 127 diamond drill holes and four trenches have investigated the Herbert Gold Property since its discovery in 1986. The 2012 drilling campaign was designed to upgrade the previously identified inferred resources to indicated resources and to test extensions of mineralization in the Main and Deep Trench veins as well as new targets in the Goat and Ridge veins.

The results of the 2012 drilling program were included in the database used by D.G. DuPre & Associates for an NI 43-101-compliant resource estimate released in a document titled “Technical Report on the Herbert Gold Property Juneau District, Southeast Alaska” and dated April 10, 2013. The updated estimate contains an indicated resource of 821,100 tonnes grading 6.91 grams per tonne gold (gpt) containing 182,400 ounces of gold in the Deep Trench and Main veins. The resource was calculated using a base case cut-off of 2 gpt. The Deep Trench and five veins that have had limited drill testing contain an inferred resource of 51,600 tonnes grading 7.73 gpt gold for a total of 12,800 ounces of gold. The mineralization is open at depth and along strike.

Herbert Gold Project
Mineral Resource Estimate

The estimate classifies resources according to proximity to the sample locations as required by NI 43-101, according to the CIM Definition Standards for Mineral Resources and Mineral Reserves. Three dimensional models were constructed from a series of cross sections for each of eight different zones. Some areas of the Main vein provided multiple options for correlations that were permissive by geology and sample geochemistry. These correlations were corrected and modified as supported by surface mapping and geology. The Deep Trench vein was remarkable in the simplicity and consistency of a very planar orientation of the correlations.

An Inverse Distance Squared (ID2) method using a block model approximately 8m x 1.5m x 6m was applied to the Main and Deep Trench veins. Smaller solids (such as the Deep Trench Vein Hanging Wall) were modeled using smaller block sizes down to 2m x 2m x 2m. Blocks required a minimum of 3 and a maximum of 12 composites within a 180m x 18m x 180m search ellipsoid, oriented parallel to the vein. Statistical studies showed that capping or averaging was not indicated. The resource remains open in multiple directions along these defined veins.

D.R. Webb P. Geol. is the Qualified Person responsible for the reserve and resource calculations while D.G. Dupre P. Geo. is the Qualified Person responsible for all other aspects of the Technical Report.

No drilling was performed during 2013. All wooden drilling platforms were dismantled and flown to an offsite location as specified in the operating permit. The third year of baseline environmental water studies was completed.

Although the 2014 Operating Plan was approved by the US Forest Service on February 27, 2014, the joint venture elected not to drill due to a lack of funds. The Company is currently in the process of monetizing non-core assets, including its 35% interest in the Herbert project. In the event that Grande Portage elects to drill before Quaterra has monetized its interest, the Company will be subject to dilution if it elects not to participate.

Acquisition costs incurred to December 31, 2014, were $164,031 and exploration expenditures were $1,595,062 for a total of $1,759,093 for its 35% interest. Acquisition costs incurred to December 31, 2013 were $150,615 and exploration expenditures were $1,579,962 for a total of $1,730,577 for its 35% interest.

The information in this section is presented in accordance with International Financial Reporting Standards, (“IFRS”) as issued by International Accounting Standards Board. The following is a discussion of our financial condition and results of operations for the fiscal years ended December 31 and should be read in conjunction with our consolidated financial statements included in Item 17 of this annual report.

Critical Accounting Estimates

The accounting estimates believed to require the most difficult, subjective or complex judgments, and which are the most critical to our reporting of results of operations and financial position, which are not limited to, are as follows:

Mineral Properties

We capitalize all costs related to the acquisition and explorationImpairment of mineral properties on a property by property basis, net of recoveries until such time as these mineral properties are placed into commercial production, sold or abandoned. If commercial production is achieved from a mineral property, the related deferred costs will be amortized prospectively on a unit-of-production basis over the estimated life

The assessment of the ore reserves. Ifimpairment indicators involves the application of a mineral property is abandoned,number of significant judgments and estimates to certain variables including metal price trends, plans for properties, and the related deferred costs are written down and expensed. From time to time, we may acquire or dispose of all or part of the mineral property interests under the terms of property option agreements. As such options are exercisable entirely at the discretion of the optionee, option payments are recorded as property costs or recoveries when paid or received.

Long-lived assets, such as equipment and deferred exploration, are reviewed for impairment at each reporting period or more frequently as economic events indicate that the carrying amount of an asset may not be recoverable.

On an ongoing basis, we evaluate each mineral property for potential impairment based on results obtained to date to determine the nature of exploration other assessment and development work, if any, that is warranted in the future and the potential for recovery of the deferred costs. If there is little prospect of future work on a property being carried out within a three-year period from completion of previous activities, the deferred costs relatedevaluation to that property are written down to the estimated amount recoverable unless there is persuasive evidence that an impairment allowance is not required.

Stock-based Compensation Expense

From time to time, we may grant share purchase options to directors, officers, employees and consultants. We use the Black-Scholes option pricing model to estimate the fair value for these options. This model, and other models which are used to value options, require inputs such as expected volatility, expected life to exercise and interest rates. Changes to any of these inputs could cause a significant change in the stock-based compensation expense charged in a period.date.

Fair value of derivative liabilities

The fairFair value of derivative liabilities that are not traded in an active market is determined by using a valuation technique. Management makes estimates and utilizes assumptions in determining the fair value for share-based payments, warrants and the (gain) loss on the revaluation of the derivative liability;liability in determining inputs to be used for the Black-Scholes option pricing model.

Income Taxes

Income tax comprises current and deferred tax. Income tax isThe critical judgments that the Company’s management has made in the process of applying the Company’s accounting policies, apart from those involving estimations, that have the most significant effect on the amounts recognized in net income (loss), exceptthe Company’s consolidated financial statements are related to the extent related to items recognized directly in equity or in other comprehensive loss.

Deferred tax is recognized in respecteconomic recoverability of temporary differences arising between the tax basesmineral properties and the assumption of assetsno material restoration, rehabilitation and liabilities and their carrying amounts in the consolidated financial statements. Deferred tax is determined on a non-discounted basis using tax rates and laws that have been enacted or substantively enacted by the reporting date and are expected to apply when the deferred tax asset or liability is settled. Deferred tax assets are recognized to the extent that it is probable that the assets can be recovered.environmental exposure.

2017 versus 2016

During the year ended December 31, 2017, the Company’s net loss was $1.242 million compared to $1.865 million and $3.104 million for the comparative periods of 2016 and 2015, respectively. Both years ended December 31, 2017 and 2016 were impacted by non-cash fair value calculations on derivative liabilities and gains or losses on disposal of assets.

The Company evaluates the carrying value of its assets at the end of each reporting period or upon a triggering event that may identify an impairment of a property’s value. During the year ended December 31, 2017, all properties were active with mineral claims and/or earn-in option payments made up to date. Despite the fact that Freeport Nevada terminated its Yerington assets Option Agreement in September 2017, the Company believes in the economic potential of its wholly owned Yerington assets and has determined to carry on exploration programs. No impairment was recorded for the year ended December 31, 2017.

During the year ended December 31, 2017, the Company spent $1.51 million in Groundhog including 4,073 feet drilling.

38

Under the Option Agreement, all SPS operating expenses including its U.S. personnel were covered by funds provided by Freeport Nevada. Since the third quarter of 2017, the Company has expensed those costs in the profit and loss resulting in a higher personnel cost in 2017.

In July 2016, the Company sold the Herbert Gold property for 1.18 million shares of Grande Portage, and recognized a $1.48 million impairment during the year ended December 31, 2016. In November 2017, Grande Portage delivered an additional 760,464 of its common shares to the Company at a market value of $185,742 pursuant to the property sale agreement.

On June 30, 2016, the Company concluded the sale of its 50% indirect interest in the Nieves silver property in Zacatecas State, Mexico, to its joint-venture partner Blackberry Ventures I, LLC. Legal fees related to the completion of this transaction resulted in a higher professional fees in 2016.

Overall, the general administrative expense of $1.53 million in 2017 was comparable to the same period in 2016 of $1.34 million. Higher personnel cost was offset by reduced professional costs; higher investor relations and communication represented the Company’s marketing and fund raising efforts.

On February 28, 2017, the Company’s shares had achieved a closing price of C$0.12 or more for 10-consecutive trading days on the TSXV, and in accordance with the terms of the convertible notes issued on July 2, 2014, the principal of the notes was automatically deemed to have been converted to shares at a rate of C$0.10 per share. The $79,973 interest portion due on some of the notes was paid in shares with the remaining interest of $53,315 paid in cash. A total of 7,489,898 shares were issued to settle the convertible notes.

As a result, a $100,000 loss on the settlement of the convertible notes was recorded during the year ended December 31, 2017, resulting from the difference between the market price of the shares issued and the conversion rate.

As at December 31, 2017, derivative liability was $587,100 compared to $938,580 at December 31, 2016. 5,721,100 warrants expired unexercised on January 2, 2018.

Interest expense (net) was primarily related to the $85,558 interest accretion on the convertible and 5% interest, compounded daily, on the $500,000 loan payable to Freeport Nevada due September 6, 2018.

2016 versus 20132015

For the year ended December 31, 2014 (“2014”),2016, the Company reportedincurred a net loss of $2,484,716 compared$1.86 million (2015 – $3.1 million). Both years were significantly affected by the non-cash fair value calculations on derivative liabilities in addition to a net lossthe write-down of $28,917,916 for prior year, the differences aremineral properties and disposal of assets in 2016.

Excluding non-cash items, general administrative expenses decreased by $0.45 million mainly due to the impairments for mineral propertiesreduction in personnel costs which were partially offset by higher administration and general office expense due to the expensed insurance premium paid in 2016.

Professional fees decreased as a result of decreased legal fees related to the Stage 2 election under the Option Agreement with Freeport Nevada during 2015. Personnel costs were lower in 2016 due to the management change in the United Statessecond half of 2015. Higher consulting costs in 2015 was related to consulting services for corporate development and central Mexico plus unrealized non cashimplementation of financing and communication strategies.

Certain warrants, including those denominated in a currency other than the Company’s functional currency are deemed to be a derivative liability and must be valued at fair value on each reporting date. Any fair value changes are recorded to profit and loss. Due to the fluctuation of the Company’s share price, a $0.45 million gain on derivative liabilities and gain on disposalwas recorded in 2016 (2015 - $1.2 million loss).
