DIFFERENCES IN UNITED STATES AND CANADIAN REPORTING PRACTICES

Financial Information

All financial information in this annual report is prepared in accordance with International Financial Reporting Standards ("IFRS"), as issued by International Accounting Standards Board ("IASB"). IFRS differs in some respects from accounting principles generally accepted in the United States, ("U.S. GAAP"), and thus our financial statements may not be comparable to financial statements of United States companies.

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") Standards. These terms are not defined in the U.S. Securities and Exchange Commission ("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 in this Annual Report on Form 20-F contains 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 NoteThe SEC has adopted final rules, that become effective on February 25, 2019, to replace SEC Industry Guide 7 with new mining disclosure rules under Regulation S-K of the U.S. Readers concerningSecurities Act (the "SEC Modernization Rules"). The new rules replace the historical property disclosure requirements included in SEC Industry Guide 7. As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of Measured Mineral Resources"measured mineral resources", "indicated 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,"inferred mineral resources". In addition, the SEC does not recognize them.has amended its definitions of "proven mineral reserves" and "probable mineral reserves" to be substantially similar to international standards. The SEC Modernization Rules are mandatory for U.S. investors are cautioned not to assume that any partreporting companies beginning with the first fiscal year commencing on or all of the Mineral Resources in these categories will ever be converted into Mineral Reserves.after January 1, 2021.

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.

EMERGING GROWTH COMPANY STATUS

The Company is an "emerging growth company" as defined in section 3(a) of the U.S. Securities Exchange Act of 1934 (as amended by the U.S. Jumpstart Our Business Startups Act (the "JOBS Act"), enacted on April 5, 2012), and the Company will continue to qualify as an "emerging growth company" until the earliest to occur of: (a) the last day of the fiscal year during which the Company has total annual gross revenues of $1,000,000,000 (as such amount is indexed for inflation every five years by the SEC) or more; (b) the last day of the fiscal year of the Company following the fifth anniversary of the date of the first sale of common equity securities of the Company pursuant to an effective registration statement under the U.S. Securities Act of 1933, as amended; (c) the date on which the Company has, during the previous three-year period, issued more than $1,000,000,000 in non-convertible debt; or (d) the date on which the Company is deemed to be a 'large accelerated filer', as defined in Rule 12b-2 of the U.S. Securities Exchange Act of 1934, as amended. The Company expects that it will continue to qualify as an emerging growth company for the foreseeable future.

The following table sets forth our selected consolidated financial data for the five years ended December 31, 20192020 which has been derived from the consolidated financial statements that have been prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by International Accounting Standards Board ("IASB").IFRS. This information should be read in conjunction with our consolidated financial statements included in Item 17 of this annual report.

Not applicable.

The Company's securities should be considered a highly speculative investment and investors should carefully consider all of the information disclosed 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 things, unprofitable efforts resulting not only from the failure to discover mineral deposits but also from finding mineral deposits, which, though present, are insufficient 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 securities. Additional risks not currently known to the Company, or that the Company currently deems immaterial, may also impair the Company's operations.

The Company may require 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 optioning certain property interests, selling certain water rights, and 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.

Failure to obtain necessary financing could result in delay or postponement of further exploration and development, and the property interests of the Company with the possible dilution or loss of such interests. Further, financing will depend upon the success of exploration programs and general market conditions for natural resources.

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

The Company has had a history of losses. None of the 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 anticipates continued losses for the foreseeable future until one or more of the properties enters into commercial production and generates sufficient revenues to fund the Company's continuing operations.

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

Historically, the Company has financed operations through the sale of equity securities 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 cannot predict the size and terms of future issuances of equity securities or debt instruments. Any transaction involving the issue of equity securities or securities convertible into common shares, could result in dilution, possibly substantial, to present and prospective 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 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 was not available to meet cash operating costs, the feasibility of continuing operations would be evaluated and if warranted, would be discontinued.

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 experienced wide fluctuations 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 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 of 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.

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 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 U.S. 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 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.

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 conditions, power outages, cave-ins, inclement weather, and mechanical equipment failure in the Company's operations. These and others 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.

Safety measures implemented by the Company may not be able to obtain insurance to cover these risks at economically feasible premiums or at all. Insurance against certain environmental risks is not generally available to the Company or to other companies within the 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.

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. 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.

TheClimate change-related risks may have a negative impact on the Company's operations, may be negatively impacted by the COVID-19 outbreak.financial position and market performance. 

The current outbreakMany governments and regulatory bodies have introduced or are contemplating regulatory changes in response to the potential impacts of climate change. These changes may create more stringent regulatory obligations, which may result in increased costs for the Company's operations. Further, these changes could also lead to new and/or more extensive monitoring and reporting requirements.

In addition, the physical risks of the novel coronavirus (COVID-19) that was first reported from Wuhan, China in December 2019,physical climate change, including temperature and precipitation shifts and more frequent and severe extreme weather events, will affect the stability and effectiveness of infrastructure and equipment, environmental protection and site closure practices, and the spreadavailability of this virus could continue to have a material adverse effect on global economic conditions whichtransportation routes. Climate change may adverselyalso impact our business. The World Health Organization declared a global emergency on January 30, 2020 with respect to the outbreakstability and characterized it as a pandemic on March 11, 2020.  Casescost of COVID-19 have been reported in 213 countries, areas or territories as of April 27, 2020, including China, the United States, Canada,water and countries in the European Union.  The extent to which the coronavirus impacts demand for commodities, including copper, will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the coronavirus and the actions to contain the coronavirus or treat its impact, among others. Moreover, the actual and threatened spread of the coronavirus globally could continue to negatively impact stock markets and adversely impact our ability to raise capital. Any of these developments, and others, could have a material adverse effect on our business.energy supplies.

The Company is a mineral exploration company engaged in the acquisition, exploration and development of copper projects currently in Nevada and Alaska, United States. The Company considers itself to be an advanced exploration stage company. The amounts shown as mineral properties represent acquisition and exploration costs incurred to date, less amounts recovered and/or written off, and do not necessarily represent present or future values. The underlying value of mineral properties and related capitalized costs are dependent on the existence of economically recoverable reserves, securing and maintaining title and beneficial interest in the properties, and obtaining necessary financing.

Three Year History

During the three-year period under review, the Company hadhas carried out exploration and development programs at its Yerington, Nevada copper properties, acquiredproperties; completed a ZTEM survey and filed an interest in a new copperindependent technical report on its Groundhog copper-gold property in Southwest Alaska,Alaska; and discontinued operations at other propertiesacquired the Butte Valley porphyry copper-gold prospect in other jurisdictions. Accordingly, a number of option agreements were terminated and properties were sold or returned to optionors as more particularly set out below.White Pine County, Nevada. Details of relevant agreements and operations are set out hereunder as "Part A - Yerington" and "Part B - Other Properties".

PART A - YERINGTON

Yerington Nevada Copper Project

Water rights sales

On September 17, 2018, the Company announced that its wholly-owned subsidiary Singatse Peak Services, LLC ("SPS") had entered into a purchase and sale agreement to sell certain primary ground water rights associated with its copper property in Yerington, Nevada, to Desert Pearl Farms LLC ("Desert Pearl"), a Yerington-based company involved in agriculture in the district, for $6.26 million.

On March 3, 2019, the Company closed the water rights sale for a final value of $6.02 million after adjusting for a small correction to one of the original permits. After the sale, the Company retained approximateapproximately 6,700 acre-feet per year of primary ground watergroundwater permitted for mining on its 51-square-mile Yerington property.

On December 19, 2019, the Company announced SPS had entered into two separate purchase and sale agreements to sell certain further primary ground water rights associated with its Yerington property to Desert Pearl and Desert Hills Dairy, LLC, two unrelated limited liability companies based in Yerington, for $1.88 million. TheBoth sales will close when the State of Nevada Division of Water Resources (NDWR) approves an application to change the manner of use of the water rights from mining and milling to agricultureclosed separately in one case, and to commercial in the other and their place of use; and title is transferred to the purchasers. Once the sale has closed,July 2020, with SPS will retainretaining about 6,000 acre-feet per year of primary ground watergroundwater permitted for mining. In addition to these primary ground water rights, SPS also has decree, supplemental and storage water rights associated with options it holds on private land over the property's Bear deposit.

Freeport Agreements

On June 16, 2014, the Company, through SPS, announced the entering into of a Membership Interest and Option Agreement (the "Option Agreement") with Freeport-McMoRan Nevada LLC ("Freeport Nevada") which set out the terms for due diligence and exploration of the Company's Yerington Assets, including the MacArthur oxide and sulfide deposits (the "MacArthur Deposit"); the Yerington pit oxide-sulfide deposit previously mined by the Anaconda Company (the "Yerington Pit"); the Bear porphyry copper deposit (the "Bear Deposit") and all other properties that SPS and Quaterra control in the Yerington District. On September 11, 2017, Freeport Nevada terminated the Option Agreement and retains no interest in the Yerington Assets.

Details of the Option Agreement, prior to termination, are summarized as follows:

Yerington Ancillary Agreements

In December 2013,February 24, 2021, the Company announced the signing of four exclusive explorationa purchase and option agreements totaling 1,305 acres of private land north and east of the Yerington Mine Site (formerly the Anaconda Mine Site) that covers portions of the Bear Deposit. In May 2015, the Company entered into an optionsale agreement to acquire a fifth property covering approximately 1,020 acressell certain primary groundwater rights to Desert Pearl for $2.91 million. $1.0 million was received on March 5, 2021.  The balance will be paid when the deal closes later this year. Once the sale has closed, SPS will retain about 5,000 acre-feet per year of additional private land covering a portion of the Bear Deposit. Under the terms of the five option agreements, Quaterra (now SPS) has the exclusive right to acquire these properties with all mineral rights and certain water rights, and to explore these parcels.primary groundwater permitted for mining.

PART B - OTHER PROPERTIES

Butte Valley, Nevada

On December 10, 2019, the Company announced two option agreements to purchase a 100% interest in the Butte Valley project located in north-central White Pine County, Nevada. The total purchase price for the two options is $850,000 paid in annual tranches over a five-year period ending in 2024 ($100,000 paid to date). A royalty is payable when production begins, which will be 1% if all buy-down options are exercised.

Butte Valley consists of 678 unpatented mining claims, and hostscovering an extensive porphyry copper-gold system discovered in the 1960s below approximately 2,000 feet of gravel and a mining-friendly state with well-developed infrastructure. Itgravity slide block. The property was last explored in 1979. During 2020 the Company has compiled all available historic data, including 15 drill hole logs and assays, several geophysical surveys and a number of geologic reports. Butte Valley fits the Company's acquisition profile and provides an opportunity to acquire a strategic land position in a mining-friendly state on reasonable terms with no onerous long-term financial obligations.

Groundhog, Alaska

On April 25, 2017, the Company announced it had signed a lease agreement with Chuchuna Minerals Company ("Chuchuna"), giving it the option to acquire a 90% interest in the Groundhog copper prospect, a 40,000-acre property, later expanded to 54,880 acres, situated on an established copper porphyry belt 200 miles southwest of Anchorage, Alaska.

Pursuant to the lease agreement, asfurther amended, on July 11, 2019, the Company agreed to fund a minimum of $1.0 million for exploration in 2017 ($1.5 million funded), and a minimum of $500,000 in each of the following years.years (total $2.5 million funded). Quaterra can earn its 90% interest in Groundhog by providing a total of $5 million in funding for exploration over sixseven years, and by paying Chuchuna a lump sum of $3 million by the end of the sixthfinal year. The Company has no obligation to exercise its option and can terminate the agreement at its discretion annually.

During 2019, the Company completed a 1,664 line kilometer ZTEM and magnetic survey covering 165 square miles of the Groundhog property. The survey identified 19 targets that are worthy of follow-up. A limited geologic reconnaissance program over the strongest ZTEM anomalies did not identify any significant geochemical anomalies, due primarily to thick overburden and scarce outcrop.

In May 2020, the Company filed an independent technical report on Groundhog which supports its assessment that the property has potential to host copper-gold mineralization similar to the nearby Pebble deposit.

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

Herbert Gold Project, Alaska

On July 14, 2016, Quaterra announced the sale of its remaining 35% participating interest in the Herbert Glacier project, Alaska, to its joint venture partner Grande Portage Resources Ltd. ("Grande Portage"). On closing, Grande Portage issued to Quaterra 1,182,331 common shares. After being issued additional shares in a financing, Quaterra now holds 1,942,795 common shares of Grande Portage. Grande Portage will also pay Quaterra $250,000 within 90 days of receipt of a feasibility report for the property or in event of a change of control or sale. Grande Portage assumed any and all obligations related to Quaterra's participating interest under the JV agreement.

Finance and Equity issuances

On January 21, 2019, the Company closed a non-brokered private placement by issuing 3,000,000 common shares at CAD 0.05 per share for gross proceeds of CAD 150,000.

On August 29 and September 20, 2018, the Company announced the closing of a non-brokered private placement in tranches by issuing secured convertible debentures for gross proceeds of $550,000 and CAD 550,000. The convertible debentures havehad a maturity date of 18 months from issuance, and bearbore a 10% interest rate per annum. Repayment of outstanding principal and interest arewere secured by a general security interest over the assets of the Company.

The convertible debentures arewere convertible into units of the Company at a price of $0.05 or CAD 0.065 per unit in the first 12 months, and $0.075 or CAD 0.10 thereafter until the maturity date. Each unit consistsconsisted of a common share and a warrant. Each warrant will entitleentitling the holder to acquire an additional common share at a price of $0.05 or CAD 0.065 for a period of four years from the closing of the private placement. The convertible debentures arewere subject to certain acceleration clauses.

In August 2019, Quaterra issued 11,769,230 units pursuant to conversions of convertible debentures having an aggregate principal amount of US$550,000$550,000 and C$CAD 50,000.  Quaterra converted the interest portion of US$44,507$44,507 due on some of the convertible debentures into 1,077,066 shares and paid the remaining $13,012 of interest in cash.

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

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 Mine property totals approximately 11 square miles. The project mineral rights consist of 2,768 acres of fee simple mineral properties and patented mining claims as well as 208 unpatented lode and placer claims totaling 4,298 acres on lands administered by the BLM.

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.

SPS owns approximately 6,7005,000 acre-feet/year of primary ground water rights that have senior priority standing. These water rights are specifically permitted for mining and milling and have significant value. Based on the price set at the close of its recent sale of water rights to a large agricultural concern in Yerington, these rights could be valued at about $20$15 million. In December 2019 the Company announced that SPS had negotiated the sale of further primary ground water rights to two unrelated entities for $1.88 million. The sales will close when the State of Nevada Division of Water Resources (NDWR) approves an application to change the manner and place of use of the water rights. Once the sale has closed, SPS will retain about 6,000 acre-feet per year of primary ground water permitted for mining and milling. In addition to these primary ground water rights, SPS also has decree, supplemental and storage water rights associated with options it holds on private land over the property's Bear deposit.

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 441 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, 28, 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, 20192020 were $5.187$3.569 million (2018(2019 - $10.578$5.187 million) net of recovery from water rights salesales and option payments made 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 6,700 acre feet5,000 acre-feet of groundwater rights and the Yerington Pit contains an estimated 45,000 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 Megawatt226-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.

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 an independent resource estimate completed by Tetra Tech under NI 43-101 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 cut-off 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 previously under the jurisdiction of the EPA is now being managed by the NDEP, a division of the Nevada Department of Conservation and Natural Resources. 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 NDEP.

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 complete one of the requirements necessary 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, NDEP and the community. The EPA/SPS 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 the fourth quarter 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.

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 was 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 was a responsible party for the operable units other than OU8, Atlantic Richfield Company, which had 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 related to OU 8 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 negotiated the terms of a Deferral Agreement, NDEP and Atlantic Richfield negotiated the terms of an Interim Administrative Order on Consent, and Atlantic Richfield and NDEP negotiated a Statement of Work for a Site-Wide Remedial Investigation and Feasibility Study.

In February 2018, the EPA and NDEP signed an agreement that transferred oversight responsibility for remediation of the Yerington mine site from the federal government to the state of Nevada. The deferral agreement requires that the responsible party fund and undertake remedial investigations, feasibility studies and cleanup of the Yerington site consistent with CERCLA standards. The cleanup, which is being overseen by NDEP, must be protective of human health, protective of ecological health, give preference for solutions that are durable over the long term, and will comply with all federal requirements as defined in CERCLA, the NCP and EPA guidance, and any more stringent state requirements.

On June 3, 2019, the Company announced that SPS had entered into an agreement with Atlantic Richfield that outlines 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. The ARC-SPS Agreement is part of a state-regulated, privately-funded solution to long-standing environmental issues associated with previous mining activity at the Anaconda Copper Mine site. SPS has complied with the terms of the agreement as required to date.

The agreement memorializes the Parties' commitments concerning cooperation, access, property rights, liabilities, federal land acquisition, and ensures preservation of SPS's property and mineral rights. The Agreement also contains covenants not to sue and indemnification provisions between the Parties.

Of particular note, the ARC-SPS agreement will:

• ● Further reduce SPS's risks regarding environmental liabilities at the Yerington site associated with past mining prior to SPS's acquisition in 2011. This includes both the former Anaconda mining operations and the former Arimetco area known as OU8, previously an unfunded liability. ARC has agreed to design, build, operate and fund the remedy for the Arimetco portion of the Site as well as to implement a CERCLA-protective remedy for the Site.

• ● Provide SPS with the opportunity to consolidate its land position at Yerington with the possible conversion of certain BLM mining claims into private land transferred to SPS at nominal cost without attached liability for previous mining activity.

• ● Dovetail with more comprehensive plans by government agencies to transfer oversight of the Yerington mine site from federal to state jurisdiction under NDEP.

• ● Assist in creating a simpler path for mine cleanup and development by way of private land ownership and state oversight.

The ARC-SPS agreement is one part of a larger set of agreements being negotiated among ARC, the EPA, NDEP and the BLM, to permanently address the impacts from previous mining activities by the Anaconda Mining Company and Arimetco Inc. at Yerington. ARC has continued its remediation activities at the site under previous orders by NDEP and the EPA. Once arrangements are completed, it will finalize cleanup of the Yerington site consistent with Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") standards. The cleanup is being overseen by NDEP.

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 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 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.

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.

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 the 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 an independent resource estimate and technical report update under NI 43-101 for the mineralization in and around the historic Yerington Pit 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 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.

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 estimateestimation 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:

¹Independent qualified person, Dr. Rex Bryan, prepared and supervised the preparation of these mineral resources.
²All estimated resources are shown using a 0.12% and 0.15% copper cutoff for oxide and sulfide respectively
³ Effective date November 20, 2013

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.

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.

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 isare planned to both expand and upgrade the current copper resources of the project prepared under NI 43-101 subject to financing and the lift of COVID-19 related restrictions in Nevada.

b. MacArthur Deposit, Nevada

Acquisition and Staking of Mineral Claims

The MacArthur Deposit consists of 897 unpatented lode claims totaling approximately 18,533 acres on lands administered by the BLM. A significant number of the claims were 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 option was exercised and the final payment of $212,000 plus interest to North was made on February 10, 2015. Quaterra's purchase is subject to a 2% NSR royalty, 1% of which may be purchased for $1,000,000, leaving a perpetual 1% NSR. The agreement with North is in good standing.

Expenditures to Date

Acquisition and exploration costs incurred by the Company for the MacArthur Deposit to December 31, 20192020 were $18.504$18.828 million (2018(2019 - $18.218$18.504 million) net of option payments made by Freeport Nevada.

Location, Access and Infrastructure

The MacArthur Deposit 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 3.5 miles south to the Yerington 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 80 miles to the northwest.  The following maps provide information on the location of the MacArthur Deposit.

History

Prior to 1989, the MacArthur Deposit was explored and drilled by several operators who have contributed to the current database of more than 740 holes totaling approximately 282,000 feet. During the early 1970s, The Anaconda Company ("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.

Arimetco purchased the property in 1989 and mined a total of six million tons at an estimated grade of 0.36 % total copper using open pit methods from the MacArthur Deposit 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. bankruptcy Code in January 1997 and suspended all operations in 2000. After Arimetco's departure, the mining claims over the deposit were allowed to lapse.

Quaterra acquired the MacArthur Deposit in August 2005. The acquisition was motivated by Quaterra's belief in the potential of the property to host an 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 fringe or top of a major copper porphyry system.

Geology

The MacArthur Deposit 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 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.

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.

Mineralization

The MacArthur Deposit 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 include: 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 Deposit. Oxide, chalcocite, and primary copper mineralization at the MacArthur Deposit 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.

Copper oxide minerals are exposed throughout the MacArthur Deposit, particularly in the 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 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 Deposit with the objective of preparing a NI 43-101 compliant resource estimate.

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 Deposit 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 RC 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 drill holes in the western and northern margins of the drilled area.

Drilling on the MacArthur Deposit was suspended through most of 2009 pending receipt of a Plan of Operations ("POO") drilling permit. On October 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. 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 RC 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 and 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 surface 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 was 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 contracted three surveys at the MacArthur Deposit in 2011 and 2012. A borehole geophysical survey and an IPR survey was 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 MacArthur 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 Anaconda's archives; and a series of historic IPR surveys (1963 - 1964) carried out by Kennecott Exploration 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 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 Deposit 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 Deposit with both RC and diamond core drilling methods. RC 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 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 RC 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.

When core from the MacArthur 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 mesh, rotary split to 1,000 grams, pulverized to -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 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 in Tucson, Arizona ("Skyline").

The MacArthur Deposit 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-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 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 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 independent resource estimate under NI 43-101 for the MacArthur Deposit preliminary economic assessment (the "MacArthur Deposit Resource Estimate") titled "MacArthur Copper Project - Amended NI 43-101 Technical Report Preliminary Economic Assessment, Lyon County, 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 resource was 71.8 million tons at 0.218% copper containing 313 million lbs. of copper, the indicated oxide and chalcocite resource was 87.3 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.

The 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 sulfide resource was 134.9 million tons averaging 0.283% copper containing 764 million lbs. of copper.

The Qualified Person for the updated MacArthur Deposit resource estimate is Dr. Rex Clair Bryan of Tetra Tech.

Metallurgy

The MacArthur Deposit 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 Deposit 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.

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

Preliminary Economic Assessment

M3 Engineering & Technology Corp. of Tucson, Arizona ("M3") completed a preliminary economic assessment for the MacArthur Deposit on May 23, 2012 and titled "MacArthur Copper Project - Amended NI 43-101 Technical Report Preliminary Economic Assessment Lyon County, 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. 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. 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 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 MacArthur Deposit PEA is Mr. Rex Henderson with M3. The Qualified Person for the mining portion of the MacArthur Deposit PEA is Herb Welhener of IMC. The 2012 PEA is available at www.sedar.com.

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

Future Plans

On January 10, 2018, Quaterra announced that it has initiated preparation of a 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 2012 PEA identified several areas for potential improvement, including additional metallurgical work and focused resource drilling. In addition, M3's review indicated that it may be more economic to buy sulfuric acid in the market than to build an acid plant to process purchased sulfur. The acid plant represented $65.4 million or 28% of the total pre-production capital costs of $232.7 million in the 2012 PEA.

Following the review and a final evaluation, and depending on the availability of funds, Quaterra intends completing a prefeasibility study in order to further de-risk MacArthur, and add more certainty to its economic potential. Specifically, as part of the prefeasibility study there will be, among others, an investigation of:

• ● Updating the resource model and optimizing the mine plan.

• ● Reducing initial capital costs by eliminating the acid plant.

• ● Ways to improve copper recovery by testing various crush sizes to replace the original plan to use Run-of-Mine (ROM) material. The new metallurgical test work program will help define the ultimate recovery, acid consumption, and leach cycle for ROM and crushed ore as well as optimal leach pad parameters. Bulk leach tests of copper oxide material are included in the test work plan.

  ● Evaluating the cost-recovery trade-offs of leaching ROM material compared with crushed material.

Quaterra has also engaged Independent Mining Consultants ("IMC") of Tucson, Arizona, to update the MacArthur mineral resource estimate by incorporating the results of work completed since the 2012 PEA, re-evaluate the assumptions in the 2012 PEA, and identify additional opportunities to enhance the mine plan.

On October 21, 2019, Quaterra announced the results of sequential copper analysis at MacArthur. Sequential copper analysis ("Seq-Cu") is a semi-quantitative technique to determine the total amount of soluble (leachable) copper present in drill samples. Actual recoverable copper will be a percentage of the soluble amount, and will depend on a number of factors including particle size, permeability and pH of the leach pad. The Seq-Cu is useful in defining the geologic, mineralogic, and metallurgical types and zones of oxidation commonly associated with porphyry-type copper deposits.

The Seq-Cu analysis work was completed by Skyline Assayers & Laboratories, Inc. of Tucson, Arizona. Evaluation of the results has been undertaken by IMC and Process Engineering LLC ("PE") also of Tucson. IMC will incorporate the data into a resource block model and mine plan in order to further de-risk the MacArthur Project and advance the project towards a prefeasibility study. 

The Seq-Cu assay work included 298 pulps from reverse circulation and drill core samples from drilling completed from 2008 to 2012. The sequential assay results provide a total copper (% TCu), acid (H₂SO₄) soluble copper (% asCu), and cyanide soluble (% CNCu) copper values. Copper Solubility (%) is calculated by the equation [(% asCu + % CNCu)/% TCu] x 100. Copper solubility provides an initial indication of how amenable the material is to heap leaching. Metallurgical testing (column leach testing) is required to assess the level of copper recovery that may be achieved in the oxide and transition zones of the deposit.

Pulps were selected to geographically and mineralogically represent the initial phases of the current mine plan. Of the 298 samples, 165 of the samples were taken from the oxide zone and 133 were taken from the transitional (chalcocite, oxide, and minor chalcopyrite) zone. The samples taken from the oxide zone average 74.5% solubility and those from the transitional zone average 79.9% solubility.  The solubility of all of the samples averages 77.1% (please see Table 1 below).  Geographically, samples from the main MacArthur pit area have the highest solubility, averaging 78.6% while those from the northern portion of the deposit average 74.4% solubility (Table 2 below). The accompanying map shows the location of the samples within the deposit area.

Quaterra has engaged IMC and PE to further evaluate the results of the Seq-Cu work with respect to the advancement of the MacArthur Project towards prefeasibility. In the near term, the Seq-Cu data will be incorporated into the resource block model to evaluate changes to the mining sequence in order to optimize project economics. As well, a plan for additional drilling will be developed to acquire fresh samples for column test work that will provide further definition of the copper recoverability from heap leaching. The initial column tests will represent areas in the deposit that will be mined during the early years of the mine schedule.

QA/QC for Seq-Cu results

Pulps were prepared from reverse circulation and core drilling from 2008 to 2012 by Skyline Assayers & Laboratories, Inc., an ISO certified assaying/geochemistry facility, in Tucson, Arizona.  During this span, pulps were returned to Quaterra and placed in a secure location. For the sequential copper analysis, Quaterra returned the pulps to Skyline where they were re-blended using their "SP-16" procedure. The samples were then analyzed for total copper and sequential copper using their "SEA-Cu" and "SEA-CuSEQ" procedures, respectively. The "SEA-Cu" procedure has a 0.01% detection limit, while the "SEA-CuSEQ" has a 0.005% detection limit. Skyline used commercially prepared standards that were placed into their sample stream and analyzed multiple duplicates to insure precision of results as a quality control measure. Quaterra has a chain of custody program to ensure sample security during all stages of sample collection, cutting, shipping, and storage.

c. Bear Deposit, Nevada

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 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 acquire these properties with all mineral rights and certain water rights, and to explore these parcels.

The Bear Deposit 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 Deposit 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 Deposit 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 resource under NI 43-101 is a high priority.

Acquisition and exploration costs incurred by the Company for the Bear Deposit to December 31, 20192020 were $1.267$1.460 million (2018(2019 - $1.012$1.267 million) net of option payments made by Freeport Nevada.

Exploration and Drilling Results

On 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 determine 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 from Hole 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 Anaconda. 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 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 square 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 54,880-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 miles south of the Groundhog claim boundary.

Acquisition and Staking of Claims

Quaterra signed a lease agreement dated April 20, 2017, asfurther amended, on July 11, 2019, with Chuchuna Minerals Company ("Chuchuna"), an Alaska corporation, giving Quaterra an option to purchase a 90% interest in the Groundhog copper prospect. Quaterra committed to funding $1 million for exploration in the first year of the agreement, and a minimum of $500,000 in each of the following fiveseven years. Quaterra can earn its 90% interest in Groundhog by providing a total of $5 million in funding for exploration over sixseven years, and by paying Chuchuna a lump sum of $3 million by the end of the sixthfinal 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 property carried to production, and a net smelter returns (NSR) royalty of 1.75%. Within the first ten years Quaterra may purchase 50% of the NSR royalty by paying Chuchuna $25 million.

Location and Access

The property is located in the Bristol Bay region of southwest Alaska, 300 km (186 mi) southwest of Anchorage within the Lake and Peninsula Borough. It lies 27 km (16 mi) north of the village of Iliamna and 10km (6 mi) west of the village 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 343 State of Alaska 160-acre claims (54,880 acres or 22,209 hectares) immediately to the northeast (3 miles) of the Pebble 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. More claims were staked in 2019, bringing the total to 343.

Regional Geology

The Groundhog property is located in the Kahiltna Terrane near the northeast trending, crustal-scale Lake Clark  fault system that separates the Kahiltna Terrane to the northwest and the Peninsular Terrane to the 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.

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 exposed units on the property and occupy the higher elevation areas encompassing most of Groundhog Mountain. It consists of a post-mineral sequence of volcanic flows and tuffaceous 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 Groundhog property is dominated by late brittle faults that cut the Tertiary 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 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.

Geophysics

Geophysical work undertaken on the property includes the following:

• ● Airborne Magnetic Survey (USGS 2001, KEX 2010).

• ● CSAMT/IP Survey  (AES 2006-7).

• ● Magnetotelluric Survey  (KEX 2010).

• ● Reconnaissance IP survey/Dipole-dipole IP Surveys  (KEX 2011, AES 2017).

Exploration and Drilling Results

The objectives of the 2017 reconnaissance drilling program were to determine the source of numerous IP anomalies identified by historic and 2017 surveys and to confirm the prospectiveness of the area for porphyry copper mineralization. Four widely-spaced core holes totaling 4,073 feet - the first ever drilled on the property - were drilled to test induced polarization (IP) anomalies 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 property by historic surveys and 26.1 kilometers of new IP completed by Zonge International in June and July this year:

• Hole 3/3A, drilled to a depth of 1,178 feet (S65E at -70 degrees), encountered strong propylitically altered Jurrasic-age gabbro-pyroxenite-basalt basement rocks in the entire hole from 0 to 1,178 feet. The strongly altered and pyritized core was uniformly anomalous in copper (25 to 612 ppm) with scattered anomalous molybdenum (trace to 177 ppm) and gold (trace to 827 ppb). The hole did not penetrate the full extent of the IP anomaly. The strong alteration and anomalous copper, molybdenum, and gold suggest that the hole may be above or adjacent to a porphyry copper system.

• Hole 4, collaredapproximately six miles south of Hole 3,encountered variably pyritized and silicified multi-phase intrusive porphyry rocks over its entire 985-foot length (S45E at -77 degrees). The dominant rock was a crowded quartz-plagioclase-potassium feldspar porphyry intruded by a more altered and mineralized feldspar porphyry, both of which were intruded by a late unmineralized intrusive breccia. The strongly altered and pyritized porphyritic rocks contain weakly anomalous copper and zinc values.
• Holes 1 and 2, drilled approximately three miles apart midway between Holes 3 and 4, intersected weak sulfide mineralization currently interpreted as Tertiary epithermal mineralization and syngenetic pyrite, respectively.

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 large sulfide anomaly(s) open laterally and at depth whose ultimate extent and source will be determined by additional surveys and deeper drilling. Data compilation and analysis will be completed and drill permits secured prior to finalizing further work plans.

Quality assurance and control

Core drilling was contracted to AES which completed four BTW core holes with a Discovery 1 drill rig. Core samples were sawed in half and sealed in heavy plastic bags into 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 commercial air carrier from Nondalton, Alaska, to Anchorage, Alaska. In Anchorage the samples were picked up by AES personnel who then inserted sample blanks from a local rock quarry approximately every tenth sample. The samples were then shipped by Lynden Transport trucks to the ALS USA's Prep Laboratory in Fairbanks, 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 by ME-MS41 ultra trace Aqua Regia ICP-MS and Au-AA23 (Au 30g fire assay with AA finish, 0.005 ppm Au detection limit). ALS routinely inserts about 15 duplicate samples, blanks, and standards with each sample shipment.

2019 exploration

During August and September 2019, Geotech of Ontario, Canada, completed a 1,664 line kilometer ZTEM and magnetic survey covering 165 square miles of the Groundhog property. A review of the data resulted in the selection of 19 targets that were ranked using ZTEM responses from similar porphyry systems, including the Pebble Project porphyry copper, gold and molybdenum deposit, which lies about five kilometers to the southwest of Groundhog. Targets were picked along a resistivity slice at 400-meters in depth from a 2D inversion. Eight top-ranked targets were selected that compare favorably in size and intensity to the ZTEM responses of other mineralized systems in Central and North American mining districts. An additional 11 target anomalies were identified that were less similar to other known deposits.

The combined interpretation of all of the geophysical data collected on the Groundhog property to date leads to grouping the ZTEM targets into two areas: the northwest sector associated with the Alpha magnetic anomaly and the southeast sector, an extension of the ZG fault zone area trending northeastward from Pebble. Additional IP and drilling will be required to evaluate these anomalies, but the timing and scope of such programs has yet to be determined. Chuchuna has expanded its land position based on ZTEM results.

A limited geologic reconnaissance program of the strongest ZTEM survey targets did not identify any significant geochemical anomalies, due primarily to thick overburden and scarce outcrop. Traverses in Groundhog Creek and White Rock Creek discovered pyritic, argillically altered crystalline igneous dike rocks of uncertain relationship with the Tertiary cover rocks. Argillically altered and pyritized volcanic rocks and gabbros were also sampled in the northern part of the White Rock Creek Canyon. Geologic work - including an IP line and a shallow drill hole in 2017 at the Alpha anomaly in the northern part of the ZTEM survey area - found areas of strong to pervasive propylitic alteration, with veined and weakly mineralized (anomalous copper to 0.18%, Mo 0.01%, Au 0.8 ppm) basalt/gabbro/pyroxenite.

ZTEM is a geophysical method that measures changes in resistivity. Because IP response (sulfides) are often associated with changes in resistivity related to various alteration types, the large area covered by the ZTEM survey will facilitate interpretation of wide-spaced ground IP lines that could result in the identification of one or more blind sulfide systems.

2020 exploration

In May 2020 the Company filed an independent technical report on Groundhog which supports its assessment that the property has potential to host copper-gold mineralization similar to the nearby Pebble deposit. The report recommends that continuing exploration efforts should focus on refining targets defined by existing geophysical surveys. Specifically, the ZTEM survey completed in September 2019 should be subjected to additional data processing (3D modeling) and integration with the existing ground-based IP surveys in order to assist in prioritizing potential drill targets.

Future plans

Previous geologic, geochemical, and geophysical studies conducted on the property by a major international mining company, identified a number of large, high priority, magnetic and induced polarization (IP) targets. It is the intention to evaluate these, and other targets identified by more recent work by Chuchuna, by mapping, sampling, additional IP and drilling.

On August 22, 2019, the Company entered into an option agreement with North Exploration, LLC, to earn a 100% interest in 600 unpatented mining claims in White Pine County, Nevada, for $600,000 over five years. North Exploration will retain a 2.5% NSR, of which 1% can be purchased for $1,000,000. A further 0.5% NSR can be purchased within the first ten years for $5,000,000.

On December 3, 2019, the Company entered another option agreement with Nevada Select Royalty, Inc., to purchase a 100% interest in 78 unpatented claims associated with the Butte Valley project, for $250,000 over five years. Nevada Select Royalty will retain a 2% NSR, of which 1% can be purchased by Quaterra for $10,000,000.

It is anticipated that the extensive data compilation of historic data completed during 2020 will be helpful in attracting a joint venture partner to drill a number of targets identified by this work.

Acquisition and exploration costs incurred by the Company for the Butte Valley to December 31, 2020 were $0.387 million (2019 - $0.186 million).

None.

The information in this section is presentedderived from the Company's consolidated financial statements, which have been prepared 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:

Impairment of mineral properties

The assessment of the impairment indicators involves the application of a number of significant judgments and estimates to certain variables including metal price trends, plans for properties, and the results of exploration and evaluation to date.

Fair value of derivative liabilities

Fair 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 in determining inputs to be used for the Black-Scholes option pricing model.

The 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 the Company's consolidated financial statements are related to the economic recoverability of the mineral properties, liquidity risk and the assumption of no material restoration, rehabilitation and environmental exposure.

2020 versus 2019

For the year ended December 31, 2020, the Company incurred a loss of $983,000 compared to $1,711,000 for the prior year. Significant differences in the comparative amounts were mainly caused by the changes in interest and accretion expense on convertible notes, the non-cash share-based compensation, and an unrealized gain (loss) on the marketable securities.

General administrative costs mainly comprise salaries, rent, investor relations, insurance, regulatory and general office costs required to maintain a publicly listed company in Canada. The scale and nature of the Company's corporate and administrative activity have remained relatively consistent over the periods presented.

The Company also spent $167,000 on the preliminary evaluation of several exploration prospects.

Interest expense of $72,000 in 2020 (2019 - $206,000) was primarily related to the convertible notes which were fully settled in 2020.

The Company holds 1,942,795 common shares of Grande Portage Resources Ltd. (trading symbol "GPG" at TSX-V). These shares are revalued at each reporting date based on the market closing price. The Company recorded an unrealized gain of $476,000 in 2020 compared to a $9,000 gain in 2019.

In August 2020, the Company settled CAD 500,000 (2019 - $550,000 and CAD 50,000) of the convertible notes by issuing 1,000,000 units (2019 - 11,769,300 units) and by making a CAD 499,233 cash payment, including interest. Each unit consisted of one common share and one share purchase warrant exercisable at CAD 0.065 until August 28, 2022. A $26,000 loss (2019 - $13,000 loss), resulting from the difference between the market price of the shares issued and the conversion rate, was recorded in the consolidated statements of loss and comprehensive loss. 

2019 versus 2018

For the year ended December 31, 2019, the Company incurred a loss of $1.711 million compared to $1.419 million for the year ended December 31, 2018. Significant differences in the comparative amounts were mainly caused by the interest and accretion expenses on convertible notes, the non-cash fair value calculation of share-based compensation, and an unrealized gain (loss) on the marketable securities.

General administrative costs are mainly comprised of salaries, rent, investor relations, insurance, regulatory and general office costs required to maintain a publicly listed company in Canada. The scale and nature of the Company's corporate and administrative activity havehas remained relatively consistent over the periods presented. The Company engaged a few consulting firms to assist the Company in expanding communications  through focused marketing, distribution and research. 

The Company assesses for any indication of impairment at each reporting date or upon a triggering event that may identify impairment of a property's value. The carrying amount of the Company's mineral properties represent mineral property costs net of recoveries and write-downs to date and does not necessarily reflect present or future values.

The fact the Company successfully sold a portion of the water rights associated with the Yerington property for gross proceeds of $6.02 million demonstrated that the potential value of the water rights alone supports the recoverability of the Company's mineral properties in Yerington.

As per the Company's accounting policy, proceeds from the water rights sale are recorded as a reduction of the carrying value of the mineral properties. To date, all mineral claims and option payments have been maintained in good standing; no impairment was recorded for the years ended December 31, 2019, and 2018.

Interest expense was primarily related to the interest on convertible notes, loans to Freeport Nevada and loans due to Dr. Thomas Patton.

The Company holds 1,942,795 common shares of Grande Portage Resources Ltd. The Company recorded an unrealized gain reflecting the changes in the market value of these shares of $9,000 during 2019 and a $130,000 loss for 2018. 

In August 2019, $550,000 and CAD 50,000 of the convertible notes were converted into 11,769,230 units consisting of one common share and one share purchase warrant. As a result, a loss resulting from the difference between the market price of the shares issued and the conversion rate was recorded in the statement of income (loss) and comprehensive income (loss). 

2018 versus 2017

For the year ended December 31, 2018, the Company incurred a loss of $1.419 million compared to $1.273 million for the year ended December 31, 2017. Losses related the marketable securities have been reclassified retrospectively from other comprehensive income (loss) to deficit upon the adoption of IFRS 9 effective January 1, 2018.  Significant differences in the comparative amounts were mainly caused by the unrealized loss on the marketable securities, the non-cash fair value calculation on share based payments, interest expenses on convertible notes, plus a onetime respective gain and loss recognized from the disposal of non-core asset and debt settlement in 2017.

Administration and office are mainly comprised of salaries, rent, insurance and general office expenses in addition to other costs related to operating a publicly listed company in Canada. The scale and nature of the Company's corporate and administrative activity has remained relatively consistent over the periods presented.

Under the option agreement with Freeport Nevada, all SPS operating expenses including its salaries for U.S. personnel and certain executive officers were funded by Freeport Nevada. For presentation purposes, these costs were presented in previous periods as part of mineral property expenditures with an associated recovery from Freeport Nevada for no net impact on mineral property carrying values. Since the termination of the option agreement, all personnel costs are expensed in the profit and loss resulting in a higher personnel cost in 2018.

Interest expense was primarily related to the interest on convertible notes, loans and extension fee paid to Freeport Nevada on the $500,000 borrowed in May 2015.

The Company holds 1,942,795 common shares of Grande Portage Resources Ltd. Of those shares, 760,464 were issued to the Company in 2017 resulting in a gain on disposal of assets of $185,742.  The Company recorded an unrealized loss reflecting the change in the market value of these shares of $129,848 during 2018 year end ($31,324 - 2017). 

The Company assesses for any indication of impairment at each reporting date or upon a triggering event that may identify an impairment of a property's value. The carrying amount of the Company's exploration and evaluation assets represent mineral property costs net of recoveries and write-downs to date and does not necessarily reflect present or future values.

The fact the Company successfully sold a portion of the water rights within Yerington property for gross proceeds of $6.02 million demonstrated that the water rights alone support the recoverability of certain of the Company's mineral properties. As per the Company's accounting policy, proceeds from the water rights sale are recorded as a reduction of the carrying value of the related mineral properties.To date all mineral claims and option payments have been maintained in good standing, no impairment was recorded for the years ended December 31, 2018 and 2017.

During the year ended December 31, 2018, the Company spent $0.11 million on Groundhog. Excess exploration expenditures from 2017 were carried forward to meet the required $500,000 minimum expenditures in 2018.

On March 16, 2017, the Company issued 7,489,898 common shares to settle the principal and certain interest on a debt entered into in July 2014. As a result, a $100,000 loss was recorded for the 2017 year end resulting from the difference between the market price of the shares issued and the conversion rate of the debt.

The Company is an exploration stage company that has not earned any production revenue. Its operation hasoperations have been dependent mainly on funding from Freeport Nevada, proceeds from salesthe sale of some of its assetswater rights in the last few years and the limited issuance of convertible notes.without diluting shareholders' value.

The Company had cash and cash equivalents of $1.81 million$701,000 on December 31, 2019 (20182020 (2019 - $0.05 million)$1,812,000). The increase in cash and cash equivalents of $1.76 million$1,111,000 decrease was mainly due to the $5.68 million$1,411,000 cash invested in proceedsmineral properties, $1,181,000 spent on general administration costs and $381,000 to repay the convertible notes, net of $1,868,000 received from the water rights sale after the cash invested in mineral properties of $1.9 million, spent in operating activities of $1.62 million and financing activities of $0.4 million.

During the year endedannounced on December 31, 2019, cash flow used in operating activities was $1.44 million before non-cash items and changes in working capital. The Company's average monthly cash burn rate was $0.12 million, and management expects a similar expenditure range in 2020. 

Net cash used in financing activities of $0.4 million consists of the net proceeds received from the private placement closed in January19, 2019, and closed during 2020.

In 2020, the 400,000 stock options exercised. The total proceeds are offset byCompany made mineral property option payments and paid all mineral claim fees, focused on the loan repayments made in March 2019 to Freeport Nevada and the Company's Chairman, Thomas Patton.

Net cash provided in investing activities reflects the $5.68 million in net proceeds of the water rights sale received in March 2019, partially offset by cash invested in the mineral properties of $1.9 million comprising of property maintenance,MacArthur pre-feasibility study preparation on MacArthur, theand Groundhog geophysical survey on Groundhog, the acquisition of Butte Valley, andplus ongoing environmental monitoring at Yerington.

The Company has entered into severalis required to pay a combined $753,000 in mineral property agreements, under which the Company is obliged, at its discretion,options and work commitment in 2021 (Bear $193,000, Wassuk $300,000, Butte Valley $100,000, and Groundhog $160,000), plus mineral claim fees, to maintain good standing of theseits mineral properties in good standing.

outstanding debt. With existing working capital and expected additional proceeds from the secondthird water rights sale, the Company believes it can sustain its operations for the next 12 months.

We do not have a research and development policy, nor do we hold any patents, licenses, or other intellectual property.

Mineral property expenditures can vary from quarter to quarter depending when option payments are due and the stage of the exploration program. For example, drilling may slow down for a period of time when results are analyzed, resulting in lower costs during that period.

We have had no revenue from mining operations since our inception. Income was generated through management fees on certain properties and interest earned on banker's acceptance investments.

None.

During the year ended December 31, 2020 the Company was charged CAD 90,000. Manex is located at the same address as the Company at Suite 1100, 1199 West Hastings Street, Vancouver, British Columbia, V6E 3T5. We believe the terms of the Manex Agreement are similar to that which would be obtainable from an unrelated party. 

On June 1, 2019, The Company entered into an investor communication service agreement with Advocate Services Ltd. ("Advocate"), another private company controlled by the Corporate Secretary. The monthly rate was CAD 4,000 for the first three months and CAD 5,000 thereafter. The Company paid CAD 60,000 for such services in 2020. Either party can terminate this service agreement at any time with 30-days written notice.

Incorporation

We are governed by notice of articles dated May 11, 2017,February 4, 2021, and articles dated June 21, 2018 (the "Articles"). Our Articles are on file with the Office of the British Columbia Registrar of Companies under Certificate of Incorporation No. BC0446713. Under the provisions of the Business Corporations Act (BC), we have the capacity and the rights, powers, and privileges of an individual of full capacity. There are no restrictions in our Articles on the business that we can carry on or the powers we can exercise.

Powers and Functions of the Directors

Under Article 17, a director is obligated to disclose a potential interest in a contract or transaction being considered by us, and may not vote on a contract or transaction with a disclosable interest, but the director shall be counted in the quorum at the meeting of the Board of Directors at which the contract or transaction is approved.

Under Article 13, the Board of Directors may, in the absence of an independent quorum, vote compensation to themselves.

Under Article 8, there are no limitations on borrowing powers exercisable by our Board of Directors.

There are no provisions in our Articles for the retirement or non-retirement of a director under an age limit.

There is no requirement in our Articles for a director to hold any of our common shares.

Rights and Restrictions Attached to the Common Shares

Our common shares rank equally as to dividend rights, voting rights, profits, and liquidation rights. The common shares are not subject to redemption or sinking fund provisions, liability to further capital calls, nor any provisions discriminating against any existing or prospective holder of such shares as a result of such shareholder owning a substantial number of shares.

Alteration of Share Rights

Subject to the Business Corporations Act (BC), our Articles provide that an ordinary resolution is required to change the rights of common shares, and must be (a) passed at a general meeting by a simple majority of the voting common shareholders; or (b) consented to in writing by a majority of not less than 2/3 of the voting common shareholders.

Annual General Meetings

Articles 10 and 11 of our Articles, together with applicable corporate and securities laws, contain the conditions governing the manner in which annual and extraordinary general meetings of shareholders are called, including notice, proxy solicitation, and quorum requirements. Annual general meetings are called and scheduled upon decision by the Board of Directors. The Board of Directors may convene an extraordinary general meeting of the shareholders. Holders of common shares may not requisition an extraordinary meeting of the shareholders. All meetings may be attended by registered shareholders or persons who hold powers of attorney or proxies given to them by registered shareholders.

Foreign Ownership Limitation

Our Articles do not contain limitations on the rights of non-residents, foreigners, or other groups to own common shares.

Change of Control

There are no provisions in our Articles that would have the effect of delaying, deferring or preventing a change in control, or that operate only with respect to a merger, acquisition or corporate restructuring involving us or any of our subsidiaries.

Share Ownership Reporting Obligation

Our Articles do not containscontain provisions governing the threshold above which shareholder ownership must be disclosed.

Differences between Canadian and U.S. Law

The securities laws of the Province of British Columbia require disclosure of shareholdings by (i) persons who are our directors or senior officers; and (ii) a person who has direct or indirect beneficial ownership of, control or direction over, or a combination of direct or indirect beneficial ownership of and control or direction over our securities carrying more than 10% of the voting rights attached to all of our outstanding voting securities.

The threshold of share ownership percentage requiring disclosure of ownership is higher in the home jurisdiction of British Columbia than the U.S. where U.S. securities law prescribes a 5% threshold for ownership disclosure.

Capital Changes

There are no conditions imposed by our Articles governing changes in our share capital that are more stringent than is required by law.

We have not entered into any material contracts other than in the ordinary course of business and other than those described in Item 4. - "Information on the Company" or elsewhere in this annual report.

There currently are no laws, decrees, regulations, or other legislation in Canada that restrict the export or import of capital, or impose foreign exchange controls or affect the remittance of interest, dividends, or other payments to non-resident holders of our common shares, other than the withholding tax requirements described under Subsection E - "Taxation" below. Canada has no system of exchange controls.

There are no limitations imposed by Canadian laws or our Articles on the right of non-resident to hold our common shares, other than as provided by the Investment Canada Act, as amended (the "Act"), as amended by the North American Free Trade Agreement Implementation Act (Canada), and the World Trade Organization (WTO) Agreement Implementation Act. The Act requires notification and, in certain cases, advance review and approval by the Government of Canada of the acquisition by a "non-Canadian" of "control of a Canadian business", all as defined in the Act. Generally, the threshold for review will be higher in monetary terms for a member of the WTO or NAFTA.

Certain Canadian Federal Income Tax Consequences

The discussion under this heading summarizes the principal Canadian federal income tax consequences of acquiring, holding and disposing of shares of common shares for a shareholder who is not a resident of Canada but is a resident of the United States and who will acquire and hold a corporation's common shares as capital property for the purposes of the Income Tax Act (Canada) (the "Canadian Tax Act"). This summary does not apply to a shareholder who carries on business in Canada through a "permanent establishment" situated in Canada or performs independent personal services in Canada through a fixed base in Canada if the shareholder's holding is effectively connected with such permanent establishment or fixed base. This summary is based on the provisions of the Canadian Tax Act and the regulations thereunder and on an understanding of the administrative practices of Canada Customs & Revenue Agency, and takes into account all specific proposals to amend the Canadian Tax Act or regulations made by the Minister of Finance of Canada as of the date hereof.

This discussion is general only and is not, nor is it intended to provide a detailed analysis of the income tax implications of any particular shareholder's interest. Investors are advised to obtain independent advice from a shareholder's own Canadian and U.S. tax advisors with respect to income tax implications pertinent to their particular circumstances. The provisions of the Canadian Tax Act are subject to income tax treaties to which Canada is a party, including the Canada-United States Income Tax Convention (1980), as amended (the "Convention").

Dividends on Common Shares and Other Income

Under the Canadian Tax Act, a non-resident of Canada is generally subject to Canadian withholding tax at the rate of 25 percent on dividends paid or deemed to have been paid to him or her by a corporation resident in Canada. The corporation is responsible for the withholding of tax at the source. The Convention limits the rate to 15 percent if the shareholder is a resident of the United States and the dividends are beneficially owned by and paid to such shareholder and to 5 percent if the shareholder is also a corporation that beneficially owns at least 10 percent of the voting stock of the payor corporation.

The amount of a stock dividend (for tax purposes) would generally be equal to the amount by which the paid up or stated capital of the corporation had increased by reason of the payment of such dividend. The corporation will furnish additional tax information to shareholders in the event of such a dividend. Interest paid or deemed to be paid on the corporation's debt securities held by non-Canadian residents may also be subject to Canadian withholding tax, depending upon the terms and provisions of such securities and any applicable tax treaty.

The Convention generally exempts from Canadian income tax dividends paid to a religious, scientific, literary, educational or charitable organization or to an organization constituted and operated exclusively to administer a pension, retirement or employee benefit fund or plan, if the organization is a resident of the United States and is exempt from income tax under the laws of the United States.

Dispositions of Common Shares

Under the Canadian Tax Act, a taxpayer's capital gain or capital loss from a disposition of a common share is the amount, if any, by which his or her proceeds of disposition exceed (or are exceeded by, respectively) the aggregate of his or her adjusted cost base of the share and reasonable expenses of disposition. The capital gain or loss must be computed in Canadian currency using a weighted average adjusted cost base for identical properties. The capital gains net of losses included in income since October 17, 2000 is 50%. The amount by which a shareholder's capital loss exceeds the capital gain in a year may be deducted from a capital gain realized by the shareholder in the three previous years or any subsequent year, subject to certain restrictions in the case of a corporate shareholder.

Under the Canadian Tax Act, a non-resident of Canada is subject to Canadian tax on taxable capital gains, and may deduct allowable capital losses realized on a disposition of "taxable Canadian property." Common shares of a corporation will constitute the taxable Canadian property of a shareholder at a particular time if the shareholder used the shares in carrying on business in Canada, or if at any time in the five years immediately preceding the disposition, 25% or more of the issued shares of any class or series in the capital stock of the corporation belonged to one or more persons in a group comprising the shareholder and persons with whom the shareholder and persons with whom the shareholder did not deal at arm's length and in certain other circumstances.

The Convention relieves United States residents from liability for Canadian tax on capital gains derived on a disposition of shares, unless: (i) the value of the shares is derived principally from "real property" in Canada, including the right to explore for or exploit natural resources and rights to amounts computed by reference to production; (ii) the shareholder was resident in Canada for 120 months during any period of 20 consecutive years preceding, and at any time during the 10 years immediately preceding, the disposition and the shares were owned by him when he ceased to be resident in Canada; or (iii) the shares formed part of the business property of a "permanent establishment" that the holder has or had in Canada within the 12 months preceding the disposition.

Certain United States Federal Income Tax Consequences

The following is a discussion of material United States federal income tax consequences generally applicable to a U.S. Holder (as defined below) of our common shares. This discussion does not cover any state, local or foreign tax consequences. This discussion is based upon the sections of the Internal Revenue Code of 1986, as amended ("the Code"), Treasury Regulations, published Internal Revenue Service ("IRS") rulings, published administrative positions of the IRS and court decisions that are currently applicable, any or all of which could be materially and adversely changed, possibly on a retroactive basis, at any time. In addition, the discussion does not consider the potential effects, both adverse and beneficial, or recently proposed legislation which, if enacted, could be applied, possibly on a retroactive basis, at any time.

U.S. Holders

As used herein, a U.S. Holder includes a holder of common shares who is a citizen or resident of the United States, a corporation (or an entity which has elected to be treated as a corporation under Treasury Regulations created or organized in or under the laws of the United States or of any political subdivision thereof, any estate other than a foreign estate (as defined in the Code) or, a trust subject to the primary supervision of a court within the United States and control of a United States fiduciary as described in the Code. This summary does not address the tax consequences to, and U.S. Holder does not include, persons subject to special provisions of federal income tax law, such as tax-exempt organizations, qualified retirement plans, financial institutions, insurance companies, real estate investment trusts, regulated investment companies, broker-dealers, non-resident alien individuals, persons or entities that have a "functional currency" other than the U.S. dollar, shareholders who hold common shares as part of a straddle, hedging or conversion transaction, and shareholders who acquired their common shares through the exercise of employee stock options or otherwise as compensation for services. This summary is limited to U.S. Holders who own common shares as capital assets. This summary does not address the consequences to a person or entity holding an interest in a shareholder or the consequences to a person of the ownership, exercise or disposition of any options, warrants or other rights to acquire common shares.

Distribution on Common Shares

U.S. Holders receiving dividend distributions (including constructive dividends) with respect to common shares are required to include in gross income for United States federal income tax purposes the gross amount of such distributions equal to the U.S. dollar value of such distributions on the date of receipt (based on the exchange rate on such date), to the extent that the corporation has current or accumulated earnings and profits, without reduction for any Canadian income tax withheld from such distributions. Such Canadian tax withheld may be credited, subject to certain limitations, against the U.S. Holder's United States federal income tax liability or, alternatively, may be deducted in computing the U.S. Holder's United States federal taxable income (see more detailed discussion at "Foreign Tax Credit" below). To the extent that distributions exceed current or accumulated earnings and profits of the corporation, they will be treated first as a return of capital up to the U.S. Holder's adjusted basis in the common shares and thereafter as gain from the sale or exchange of the common shares. Dividend income will be taxed at marginal tax rates applicable to ordinary income while preferential tax rates for long-term capital gains are applicable to a U.S. Holder which is an individual, estate or trust. There are currently no preferential tax rates for long-term capital gains for a U.S. Holder which is a corporation.

In the case of foreign currency received as a dividend that is not converted by the recipient into U.S. dollars on the date of receipt, a U.S. Holder will have a tax basis in the foreign currency equal to its U.S. dollar value on the date of receipt. Gain or loss may be recognized upon a subsequent sale of other disposition of the foreign currency, including the exchange for U.S. dollars.

Dividends paid on the common shares of a corporation will not generally be eligible for the dividends received deduction provided to corporations receiving dividends from certain United States corporations. A U.S. Holder which is a corporation may, under certain circumstances, be entitled to a 70% deduction of the United States source portion of dividends received from a corporation (unless the corporation qualifies as a "foreign personal holding company" or a "passive foreign investment company", as defined below) if such U.S. Holder owns shares representing at least 10% of the voting power and value of the corporation. The availability of this deduction is subject to several complex limitations which are beyond the scope of this discussion.

Foreign Tax Credit

A U.S. Holder who pays (or has withheld from distributions) Canadian income tax with respect to the ownership of common shares may be entitled, at the option of the U.S. Holder, to either a deduction or a tax credit for such foreign tax paid or withheld. Generally, it will be more advantageous to claim a credit because a credit reduces United States Federal income taxes on a dollar-for-dollar basis, while a deduction merely reduces the taxpayer's income subject to tax. This election is made on a year-by-year basis and applies to all foreign income taxes (or taxes in lieu of income tax) paid by (or withheld from) the U.S. Holder during the year. There are significant and complex limitations which apply to the credit, among which is the general limitation that the credit cannot exceed the proportionate share of the U.S. Holder's United States income tax liability that the U.S. Holder's foreign source income bears to his/her or its worldwide taxable income. The various items of income and deduction must be classified into foreign and domestic sources. Complex rules govern this classification process. In addition, this limitation is calculated separately with respect to specific classes of income such as "passive income", "high withholding tax interest", "financial services income", "shipping income", and certain other classifications of income. Dividends distributed will generally constitute "passive income" or, in the case of certain U.S. Holders, "financial services income" for these purposes. The availability of the foreign tax credit and the application of the limitations on the credit are fact specific and holders and prospective holders of common shares of should consult their own tax advisors regarding their individual circumstances.

For individuals whose entire income from sources outside the United States consists of qualified passive income whose total amount of creditable foreign taxes paid or accrued during the taxable year does not exceed $300 ($600 in the case of a joint return) and for whom an election is made under section 904(j), the limitation on credit does not apply.

Disposition of Common Shares

A U.S. Holder will recognize gain or loss upon the sale of common shares equal to the difference, if any, between (i) the amount of cash plus the fair market value of any property received, and (ii) the tax basis in the common shares. Preferential tax rates apply to long-term capital gains of U.S. Holders which are individuals, estates, or trusts. This gain or loss will be capital gain or loss if the common shares are capital assets in the hands of the U.S. Holder, which will be a short-term or long-term capital gain or loss depending upon the holding period of the U.S. Holder. Gains and losses are netted and combined according to special rules in arriving at the overall capital gain or loss for a particular tax year. Deductions for net capital losses are subject to significant limitations. For U.S. Holders which are not corporations, any unused portion of such net capital loss may be carried over to be used in later tax years until such net capital loss is thereby exhausted, but individuals may not carry back capital losses. For U.S. Holders which are corporations (other than corporations subject to Subchapter S of the Code), an unused net capital loss may be carried back three years from the loss year and carried forward five years from the loss year to be offset against capital gains until such net capital loss is thereby exhausted.

Foreign Personal Holding Company

If at any time during a taxable year more than 50% of the total combined voting power or the total value of the our outstanding shares is owned, actually or constructively, by five or fewer individuals who are citizens or residents of the United States and 60% (50% after the first tax year) or more of our gross income for such year was derived from certain passive sources, then we would be treated as a "foreign personal holding company." In that event, U.S. Holders that hold common shares would be required to include in gross income for such year their allocable portions of such passive income to the extent we do not actually distribute such income.

We do not believe we currently have the status of a "foreign personal holding company". However, there can be no assurance that we will not be considered a foreign personal holding company for any future taxable year.

Passive Foreign Investment Company

As a foreign corporation with U.S. Holders, we potentially could be treated as a passive foreign investment company ("PFIC"), as defined in Section 1297 of the Code, depending upon the percentage of our income which is passive, or the percentage of our assets which are held for the purpose of producing passive income. We believe we currently are a PFIC.

The rule governing PFICs can have significant tax effects on U.S. Holders of foreign corporations. These rules do not apply to non-U.S. Holders. Section 1297 of the Code defines a PFIC as a corporation that is not formed in the United States and, for any taxable year, either (i) 75% or more of its gross income is "passive income", which includes interest, dividends and certain rents and royalties or (ii) the average percentage, by fair market value (or, if the corporation is a controlled foreign corporation or makes an election, by adjusted tax basis), of its assets that produce or are held for the production of "passive income" is 50% or more. The taxation of a US Holder who owns stock in a PFIC is extremely complex and is therefore beyond the scope of this discussion. U.S. Holders should consult with their own tax advisors with regards to the impact of these rules.

Controlled Foreign Corporation

If more than 50% of the voting power of all classes of our common shares entitled to vote is owned, actually or constructively, by citizens or residents of the United States, United States partnerships, corporations, or estates or trusts other than foreign estates or trusts, each of whom own actually or constructively own 10% or more of the total combined voting power of all classes of our capital stock ("United States Shareholders"), then we would be a "controlled foreign corporation" (CFC). We do not believe we currently are a CFC.

The CFC classification would affect many complex results, one of which is that certain income of a CFC would be subject to current U.S. tax. The United States generally taxes United States Shareholders of a CFC currently on their pro rata shares of the Subpart F income of the CFC. Such United States Shareholders are generally treated as having received a current distribution out of the CFC's Subpart F income and are also subject to current U.S. tax on their pro rata shares of the CFC's earnings invested in U.S. property. The foreign tax credit described above may reduce the U.S. tax on these amounts. In addition, under Section 1248 of the Code, gain from the sale or exchange of shares by a U.S. Holder of common shares of a corporation which is or was a United States Shareholder at any time during the five-year period ending with the sale or exchange is treated as ordinary income to the extent of earnings and profits of the corporation (accumulated only while the shares were held by the United States Shareholder and while the corporation was a CFC attributable to the shares sold or exchanged). If a foreign corporation is both a PFIC and a CFC, the foreign corporation generally will not be treated as a PFIC with respect to the United States Shareholders of the CFC. This rule generally will be effective for taxable years of United States Shareholders beginning after 1997 and for taxable years of foreign corporations ending with or within such taxable years of United States Shareholders. The PFIC provisions continue to apply in the case of a PFIC that is also a CFC with respect to the U.S. Holders that are less than 10% shareholders.

PART II

None.

Effective June 21, 2018, in accordance with the vote of shareholders at the 2018 Annual General Meeting, we adopted a rights plan applicable to our common shares (the "Rights Plan"). This Rights Plan replaced an earlier shareholder rights plan dated June 12, 2013. The Rights Plan will remain in effect until termination of the annual meeting of shareholders in 2021 unless the shareholders vote by ordinary resolution at that meeting to ratify and confirm the Rights Plan. 

The purpose of the Rights Plan is to ensure, to the extent possible, that all shareholders are treated equally and fairly in connection with any take-over bid or similar proposal to acquire our common shares. Take-over bids may be structured in such a way as to be coercive or discriminatory in effect, or may be initiated at a time when it will be difficult for our Board of Directors to prepare an adequate response. Such offers may result in shareholders receiving unequal or unfair treatment, or not realizing the full or maximum value of their investment in us.

The Rights Plan discourages the making of any such offers by creating the potential of significant dilution to any offeror who does so. This potential is created through the issuance to all shareholders of contingent rights to acquire additional common shares of the Company at a significant discount to then prevailing market prices, which could, in certain circumstances, become exercisable by all shareholders other than an offeror and its associates, affiliates and joint actors.

An offeror can avoid that potential by making an offer that either: (i) qualifies as a "Permitted Bid" under the Rights Plan, and therefore meets certain specified conditions (including a minimum deposit period of 105 days) which aim to ensure that all shareholders are treated fairly and equally; or (ii) does not qualify as a "Permitted Bid" but is negotiated with and has been exempted by our Board of Directors from the application of the Rights Plan in light of the opportunity to bargain for agreed terms and conditions to the offer that are believed to be in the best interests of shareholders.

Disclosure Controls and Procedures

Our management carried out an evaluation, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the fiscal year covered by this report. Based on the evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2019,2020, our disclosure controls and procedures were effective.

Management's Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting ("ICFR") as such term is defined in Rule 13a-15(f) or Rule 15d-15(f) promulgated under the Exchange Act. Management (under the supervision and with the participation of the Chief Executive Officer and the Chief Financial Officer) assessed the effectiveness of our ICFR as of December 31, 2019,2020, using the framework set forth in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO 2013 framework). Based on this assessment, our management concluded that our ICFR were effective as of December 31, 2019.2020.

This annual report does not include an attestation report of our registered public accounting firm regarding our ICFR. Our management's report was not subject to attestation by our registered independent public accounting firm because we are not an accelerated filer or large accelerated filer and exempt as an Emerging Growth Company.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting during the fiscal year ended December 31, 20192020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Our Board of Directors has determined that Terrence Eyton is an "audit committee financial expert", as defined in Item 16A(b) of Form 20-F, serving on the Audit Committee of the Company as within the criteria prescribed under SEC.

We have adopted a Code of Business Conduct and Ethics for all our directors, officers, and employees. It includes a Code of Ethical Conduct for Financial Managers that applies to our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. The Code of Business Conduct and Ethics is available in the Governance section of our website at www.quaterra.com. All applicable amendments to and waivers of the Code of Business Conduct Ethics governing our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions will be posted on our website and furnished to the SEC on Form 6-K.

The Company will provide to any person without charge, upon request via email at info@quaterra.com, a copy of the Code of Business Conduct and Ethics.

The following table shows the aggregate fees billed to us by our independent auditor PricewaterhouseCoopers LLP for 20192020 and 2018,2019, in each of the last two fiscal years.

Audit fees are the aggregate fees billed by the Company's independent auditor for the audit of the Company's annual consolidated financial statements, reviews of interim consolidated financial statements and attestation services that are provided in connection with statutory and regulatory filings or engagements.

Audit-related fees are fees charged by the Company's independent auditor for assurance and related services that are reasonably related to the performance of the audit or review of financial statements and are not reported under "Audit Fees".

Tax fees are fees for professional services rendered by the Company's independent auditors for tax compliance and tax advice on actual or contemplated transactions.

The Audit Committee recommends to the Board of Directors the external auditor to perform audit, review, and attestation services. The Audit Committee pre-approves all non-audit services provided by our external auditors, and pre-approved the tax fees and the all other fees listed in the table above.
