BASIS OF PREPARATION
BASIS OF PREPARATION	2. BASIS OF PREPARATION Statement of compliance and basis of presentation These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board ("IASB"). These consolidated financial statements have been prepared on a historical cost basis except for financial instruments classified as fair value through profit or loss (“FVTPL”), which are stated at their fair value. Management is actively managing the effects of an outbreak of the novel coronavirus (“COVID-19”) at its Brucejack Mine subsequent to year end, including the impact on the Company’s operations and its liquidity. The impact of the outbreak of COVID-19 is uncertain, and COVID-19 could have a significant impact on production, financial results and liquidity if the Company or its suppliers or customers are not able to maintain operations. As at December 31, 2020, the Company has available liquidity of $335,104 which includes cash and cash equivalents of $174,753 and the undrawn portion of the revolving facility of $160,351. Refer to note 23 for further discussion about the COVID-19 outbreak. These consolidated financial statements were authorized for issue by the Board of Directors on February 25, 2021.

SIGNIFICANT ACCOUNTING POLICIES
SIGNIFICANT ACCOUNTING POLICIES	3. SIGNIFICANT ACCOUNTING POLICIES Basis of consolidation These consolidated financial statements include the financial statements of the Company and the entities controlled by the Company, its subsidiaries, listed in the following table: Name of subsidiary Place of Proportion of Principal activity Pretium Exploration Inc. BC, Canada 100% Operates the Brucejack Mine 0890696 BC Ltd. BC, Canada 100% Holds real estate in Stewart, BC Control is defined as the exposure, or rights, to variable returns from involvement with an investee and the ability to affect those returns through power over the investee. Power over an investee exists when the Company has existing rights that give the Company the ability to direct the activities that significantly affect the investee’s returns. This control is generally evidenced through owning more than 50% of the voting rights or currently exercisable potential voting rights of a subsidiary’s share capital. The financial statements of subsidiaries are included in the consolidated financial statements from the date that control commences until the date that control ceases. Intercompany balances and transactions, including any unrealized income and expenses arising from intercompany transactions, are eliminated in preparing the consolidated financial statements. Foreign currency translation Functional and presentation currency Items included in the financial statements of each consolidated entity are measured using the currency of the primary economic environment in which the entity operates (the “functional currency”). The functional currency of the Company and its subsidiaries is the United States dollar (“USD”), which is also the Company’s presentation currency. References to “$” or “USD” are to United States dollars, while references to “C$” or “CAD” are to Canadian dollars. Transactions and balances Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions or valuations where items are re-measured. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at period end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the statement of earnings (loss) for the year. Financial instruments Financial assets – Classification Financial assets are classified at initial recognition as either: measured at amortized cost, FVTPL or fair value through other comprehensive income (“FVOCI”). The classification depends on the Company’s business model for managing the financial assets and the contractual terms which give rise to the cash flows. For assets measured at fair value, gains and losses will either be recorded in earnings (loss) or other comprehensive income (“OCI”). For investments in debt instruments, this will depend on the business model for which the investment is held. For investments in equity instruments that are not held for trading, this will depend on whether the Company has made an irrevocable election at the time of initial recognition to account for the equity investment at FVOCI. The Company reclassifies debt investments when and only when its business model for managing those assets changes. Financial assets – Measurement At initial recognition, the Company measures a financial asset at its fair value plus, in the case of a financial asset not at FVTPL, transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at FVTPL are expensed in the statement of earnings (loss). Financial assets with embedded derivatives are considered in their entirety when determining whether their cash flows are solely payment of principal and interest. Subsequent measurement of debt instruments depends on the Company’s business model for managing the asset and the cash flow characteristics of the asset. There are three measurement categories into which the Company classifies its debt instruments: · Amortized cost – Assets that are held for collection of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortized cost. A gain or loss on a debt investment that is subsequently measured at amortized cost and is not part of a hedging relationship is recognized in earnings (loss) when the asset is derecognized or impaired. Interest income from these financial assets is included in interest and finance income using the effective interest rate method. · FVOCI – Assets that are held for collection of contractual cash flows and for selling the financial assets, where the assets cash flows represent solely payments of principal and interest, are measured at FVOCI. Movements in the carrying amount are taken through OCI, except for the recognition of impairment gains or losses, interest income and foreign exchange gains and losses which are recognized in earnings (loss). When the financial asset is derecognized, the cumulative gain or loss previously recognized in OCI is reclassified from equity to earnings (loss) and recognized in other gains (losses). Interest income from these financial assets is included in interest and finance expense using the effective interest rate method. Foreign exchange gains and losses are presented in foreign exchange gain (loss) and impairment expenses in other expenses. · FVTPL – Assets that do not meet the criteria for amortized cost or FVOCI are measured at FVTPL. A gain or loss on a debt investment that is subsequently measured at FVTPL and is not part of a hedging relationship is recognized in earnings (loss) and presented net in the statement of earnings (loss) within other gains (losses) in the period in which it arises. Changes in the fair value of financial assets at FVTPL are recognized in gain (loss) on financial instruments at fair value in the statement of earnings (loss) as applicable. Cash and cash equivalents and restricted cash Cash and cash equivalents comprise cash holdings in business and savings accounts held at major financial institutions with an original maturity date of three months or less. Restricted cash is held at major financial institutions as collateral for reclamation bonds. Cash and restricted cash are classified at amortized cost. Interest income is recognized by applying the effective interest rate method. Receivables and other The Company’s trade receivables result from sales transactions in accordance with IFRS 15, Revenue from Contracts with Customers and contain provisional pricing arrangements. These trade receivables are classified as FVTPL with the gain (loss) included in revenue. Accounts payable and accrued liabilities and debt Accounts payable and accrued liabilities, the debt portion of the convertible notes and the senior secured loan facility are recognized initially at fair value, net of any directly attributable transaction costs. Subsequent to initial recognition these financial liabilities are held at amortized cost using the effective interest method. Derivatives Derivative instruments, including embedded derivatives in financial liabilities or non-financial contracts, such as the offtake obligation, and non-hedge derivatives, such as foreign exchange contracts, are recorded at FVTPL and, accordingly, are recorded on the statement of financial position at fair value. Fair values for derivative instruments are determined using valuation techniques, with assumptions based on market conditions existing at the statement of financial position date. Changes in fair value at each reporting date are included in the statement of earnings (loss) as gain (loss) on financial instruments at fair value. Inventories Ore stockpiles, in-circuit and finished metal inventory (gold and silver) are valued at the lower of weighted average production cost and net realizable value. Production costs include the cost of raw materials, direct labour, mine-site overhead expenses and applicable depreciation and depletion of mineral properties, plant and equipment. Net realizable value is calculated as the estimated price at the time of sale based on prevailing and long-term metal prices less estimated future production costs to convert the inventories into saleable form and estimated costs to sell. Ore stockpile inventory represents mined ore on the surface or underground that is available for further processing. In-circuit inventory represents material in the mill circuit that is in the process of being converted into a saleable form. Finished metal inventory represents gold and silver doré and concentrate located at the mine, in transit to customers and at refineries. Materials and supplies inventories are valued at the lower of weighted average cost and net realizable value. Replacement costs of materials and spare parts are generally used as the best estimate of net realizable value. Any write-downs of inventory to net realizable value are recorded within cost of sales in the statement of earnings (loss). If there is a subsequent increase in the value of inventory, the previous write-downs to net realizable value are reversed up to cost to the extent that the related inventory has not been sold. Mineral properties Mineral properties are measured at cost less accumulated depletion and accumulated impairment losses. Mineral properties include the fair value attributable to mineral reserves and mineral resources acquired in a business combination or asset acquisition, mine development costs and previously capitalized exploration and evaluation costs. Upon commencement of production, a mineral property is depleted using the unit-of-production method. Unit-of-production depletion rates are determined using gold ounces mined over the estimated proven and probable mineral reserves of the mine. Development costs incurred during production The Company incurs development costs to build new raises and ramps (vertical development) that enable the Company to physically access ore underground. The time over which these costs will be incurred depends on the mine life. These underground development costs are capitalized as incurred. Capitalized underground development costs incurred to enable access to specific areas of the mine and which only provide an economic benefit over a specific period of mining are depleted using a unit-of-production method determined using gold ounces mined over the estimated proven and probable mineral reserves in that particular area of the mine. Plant and equipment Plant and equipment are measured at cost less accumulated depreciation and accumulated impairment losses. The initial cost of an asset is comprised of its purchase price or construction cost, any costs directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management and the estimated future cost of dismantling and removing the asset at the end of its useful life. The purchase price or construction cost is the fair value of consideration to acquire the asset. Depreciation of plant and equipment commences when the asset has been fully commissioned and is available for its intended use. A majority of mine and site infrastructure assets, including buildings, roads and transmission lines are depreciated using a unit-of-production method over the life of mine. Depreciation is determined using gold ounces mined over the estimated proven and probable mineral reserves of the mine. The Company reviews estimated proven and probable mineral reserves annually and when facts and circumstances indicate that a review should be performed. Changes to estimated proven and probable mineral reserves are accounted for prospectively. Depreciation of other assets, including those ancillary to the mine are calculated using the straight-line method to allocate cost over the estimated useful lives, as follows: Asset class Estimated useful life Mine and mill equipment 5 - 13 years Light vehicles 3 - 5 years Office and computer equipment 3 - 5 years Leasehold improvements Term of lease When significant components of an asset have different useful lives, depreciation is calculated on each separate component. Each asset or component’s estimated useful life has due regard to both its own physical life limitations and the present assessment of economically recoverable mineral reserves of the Brucejack Mine. Depreciation methods and estimated useful lives and residual values are reviewed annually and when facts and circumstances indicate that a review should be performed. Changes in estimates are accounted for prospectively. Expenditures on major maintenance or repairs includes the cost of an asset’s replacement parts and overhaul costs. Where an asset or part of an asset is replaced, and it is probable that future economic benefits associated with the item will be available to the Company, the expenditure is capitalized and the carrying amount of the item replaced is derecognized. Similarly, overhaul costs associated with major maintenance are capitalized and depreciated over their useful lives where it is probable that the future economic benefits will be available and any remaining carrying amounts of the cost of previous overhauls are derecognized. All other costs are expensed as incurred. An item of plant and equipment is derecognized upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. Any gain or loss arising on disposal of the asset, determined as the difference between the net disposal proceeds and the carrying amount of the asset, is recognized in the statement of earnings (loss). Construction in progress Costs recorded for assets under construction are capitalized as construction in progress. On completion, the cost of construction is transferred to the appropriate category of mineral properties, plant and equipment. No depreciation is recorded until the assets are substantially complete and available for their intended use. Borrowing costs Borrowing costs that are directly attributable to the acquisition, construction or production of an asset that takes a substantial period of time to prepare for its intended use are capitalized as part of the cost of the asset. Capitalization of borrowing costs begins when there are borrowings, and activities commence to prepare an asset for its intended use. Capitalization of borrowing costs ends when substantially all activity necessary to prepare a qualifying asset for its intended use are complete. When proceeds of project-specific borrowings are invested on a temporary basis, borrowing costs are capitalized net of any investment income. Exploration and evaluation expenditures Exploration and evaluation expenditures include the costs of acquiring licenses and costs associated with exploration and evaluation activity. Exploration and evaluation expenditures are capitalized. Mineral property acquisition costs are capitalized. Exploration and evaluation costs incurred before the Company has obtained the legal rights to explore an area are expensed. Once the technical feasibility and commercial viability of the extraction of mineral reserves or mineral resources from a particular mineral property has been determined, expenditures are reclassified to mineral properties within mineral properties, plant and equipment. The establishment of technical feasibility and commercial viability of a mineral property is assessed based on a combination of factors, including: · The extent to which mineral reserves or mineral resources as defined in National Instrument 43‑101, Standards of Disclosure for Mineral Projects (“NI 43-101”) have been identified through a feasibility study or similar document; · The results of optimization studies and further technical evaluation carried out to mitigate project risks identified in the feasibility study; · The status of environmental permits; and · The status of mining leases or permits. Exploration and evaluation assets are tested for impairment immediately prior to reclassification to mineral properties. Effective January 1, 2021, management will adopt a change to its accounting policy related to exploration and evaluation expenditures. Refer to note 5 of these consolidated financial statements for further details. Mineral interests Mineral interests consist of acquired royalty interests pursuant to purchase agreements on exploration and evaluation stage projects. Mineral interests are recorded at cost. Mineral interests are subsequently measured at cost less accumulated depletion and accumulated impairment losses, if any. Mineral exploration tax credits Mineral exploration tax credits on eligible mineral exploration expenditures incurred are treated as a reduction of capitalized mineral properties, plant and equipment. The credits are recorded as a receivable when the amount is reliably measurable, and it is considered probable that the tax credit will be recovered. Impairment of non-financial assets The carrying amounts of assets included in mineral properties, plant and equipment are reviewed for impairment whenever facts and circumstances suggest that the carrying amounts may not be recoverable. If there are indicators of impairment, the recoverable amount of the asset is estimated in order to determine the extent of any impairment. Where the asset does not generate cash flows that are independent from other assets, the recoverable amount of the cash generating unit ("CGU") to which the asset belongs is determined. The recoverable amount of an asset or CGU is determined as the higher of its fair value less costs of disposal (“FVLCD”) and its value in use. An impairment loss exists if the asset's or CGU's carrying amount exceeds the recoverable amount and is recorded as an expense immediately. Fair value is the price that would be received from selling an asset in an orderly transaction between market participants at the measurement date. Costs of disposal are incremental costs directly attributable to the disposal of an asset. Future cash flows are estimated using the following significant assumptions: mineral reserves and mineral resources, production profile, operating costs, capital costs, commodity prices, foreign exchange rates and discount rates. All inputs used are those that an independent market participant would consider appropriate. Value in use is determined as the present value of the future cash flows expected to be derived from continuing use of an asset or cash generating unit in its present form. These estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset or cash generating unit for which estimates of future cash flows have not been adjusted. Tangible assets that have been impaired in prior periods are tested for possible reversal of impairment whenever events or changes in circumstances indicate that the impairment has reversed. If the impairment has reversed, the carrying amount of the asset is increased to its recoverable amount, but not beyond the carrying amount that would have been determined had no impairment loss been recognized for the asset in the prior periods. A reversal of an impairment loss is recognized into earnings (loss) immediately. Leases At the inception of a contract, the Company assesses whether a contract is, or contains, a lease based on whether the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset, the Company assesses whether: · The contract involves the use of an identified asset, either explicitly or implicitly, including consideration of supplier substitution rights; · The Company has the right to obtain substantially all the economic benefits from the use of the asset throughout the period of use; and · The Company has the right to direct the use of the asset. The right of use ("ROU") asset is initially measured based on the initial amount of the lease obligation plus any initial direct costs incurred less any lease incentives received. The assets are depreciated to the earlier of the end of the useful life of the ROU asset or the lease term using either the straight-line or units-of-production method depending on which method more accurately reflects the expected pattern of consumption of the future economic benefits. The lease term includes periods covered by an option to extend if the Company is reasonably certain to exercise that option. The ROU asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease obligation. The lease obligation is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company's incremental borrowing rate. Generally, the Company uses its incremental borrowing rate as the discount rate. The lease obligation is measured at amortized cost using the effective interest method and remeasured when there is a change in future lease payments. Future lease payments can arise from a change in an index or rate, if there is a change in the Company's estimate of the expected payable under a residual value guarantee, or if the Company changes its assessment of whether it will exercise a purchase, extension or termination option. When the lease obligation is remeasured, a corresponding adjustment is made to the carrying amount of the ROU asset, or is recorded to the statement of earnings (loss) if the carrying amount of the ROU asset has been reduced to zero. Decommissioning and restoration provision The Company has provisions for decommissioning and restoration costs which include the dismantling and demolition of infrastructure and the removal of residual materials and remediation of disturbed areas. Decommissioning and restoration costs are a normal consequence of mining and a majority of decommissioning and restoration expenditures are expected to be incurred at the end of the life of mine. Decommissioning and restoration costs are estimated and discounted to their net present value and capitalized to the carrying amount of the related asset along with the recording of a corresponding liability, as soon as the obligation to incur such costs arises. The discount rate used to calculate the net present value is a pre-tax rate of similar maturity that reflects current market assessment of time value of money and the risks specific to the liability. Each period the Company reviews cost estimates and other assumptions used in the valuation of the provision to reflect events, changes in circumstances and new information available. The liability is adjusted each reporting period for the unwinding of the discount, changes to the current market-based discount rate and for the amount or timing of the underlying cash flows needed to settle the provision. Share capital Common shares are classified as equity. Transaction costs directly attributable to the issue of common shares and share options are recognized as a deduction from equity, net of any tax effects. Revenue recognition The Company produces doré and concentrates which contain both gold and silver. The doré is further processed to produce refined metals for sale. The concentrates are sold to traders in concentrate form. The Company’s performance obligations relate primarily to the delivery of mine production in refined or concentrate form to its customers. Revenue is recognized when control is transferred to the customer. Control transfers when a product is delivered to the customer, the customer has full discretion over the product and there is no unfulfilled obligation that could affect the customer’s acceptance of the product. Control over the refined gold or silver produced from doré is transferred to the customer and revenue recognized upon delivery to the customer’s bullion account. For shipment of doré, approximately 95% - 99% of the estimated contained gold is available to be delivered to the customer's bullion account within approximately 10 days of arrival at the refinery. The balance of the contained gold is delivered to the customer's bullion account following the final processing outturn. The contained silver is sold following the final processing outturn. Control over gold and silver bearing concentrates is transferred to the customer and revenue recognized when the concentrates are loaded or available for loading onto the vessel at the port of discharge. Revenue from concentrate sales are recognized net of treatment costs and refining charges. Revenue is recognized at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring the product to the customer. Sales of refined gold are recorded at the spot price on the date of delivery to the customer’s bullion account with payment received on the same day. Sales of silver are recorded at the spot price on the date of sale. Concentrate sales are recorded at the provisional price based on the estimated forward price to the date of final settlement. The final purchase price for these gold concentrate sales will be the average price for a period of time following the bill of lading date depending on the customer. Adjustments are made in subsequent periods to the customer receivables for these sales transactions based on movements in market prices prior to final pricing. As a result, concentrate sales receivables are fair valued and adjusted each period to reflect forward market prices to the estimated settlement date. These changes in fair value are included in revenue on the statement of earnings (loss). The Company receives payment for 90% – 92.5% of the value of each concentrate shipment 5 – 15 days after the loading of the material at the port of discharge. A final payment for 8.5% - 10% of the value of each sale is received upon completion of final assays and final pricing based on a defined pricing period. Revenue recognition under the offtake agreement (2019) Under the offtake agreement, the Company was required to deliver gold equivalent to 100% of production up to 7,067,000 ounces (note 10). Refined gold and silver were delivered directly to the offtakers and recorded at the spot price on the date of delivery. The final purchase price to be paid under the offtake agreement was, at the purchaser’s option, a market referenced gold price in USD per ounce during a defined pricing period after the date of each sale. The difference between the spot price on the date of sale and the price paid by the purchaser reflected the settlement of a portion of the offtake obligation previously recorded on the statement of financial position. The Company received payment for 90% of the value of each gold sale within 2 days of the date of sale. A final payment for 10% of the value of each gold sale, taking into account the purchaser’s pricing option, was received on the 7 th day after the date of sale. The Company repurchased 100% of the offtake agreement on September 30, 2019 eliminating the Company’s obligation to deliver gold to the holders of the offtake agreement. Share-based payments Share options Options granted to employees under the Company’s equity settled share-based option plan are measured at fair value at the date of grant. Fair value is determined using the Black-Scholes option pricing model, which relies on estimates of the risk-free interest rate, expected share price volatility, future dividend payments and the expected average life of the options. The fair value determined at the grant date is recognized as an expense over the vesting period in accordance with the vesting terms and conditions (graded vesting method), with a corresponding increase in contributed surplus in equity. Restricted share units (“RSU’s”) RSU’s are granted to employees of the Company and are expected to be settled in cash. The fair value of a RSU is estimated based on the quoted market price of the Company’s common shares. The initial fair value of the liability is calculated as of the grant date and is recognized as share-based compensation expense in the statement of earnings (loss) on a graded vesting basis over the vesting period. Subsequently, at each reporting date and on settlement, the liability is re-measured with any changes in fair value recorded to the statement of earnings (loss) Performance share units (“PSU’s”) PSU’s are granted under the Company’s RSU Plan and are expected to be settled in cash. The number of units to be issued on the vesting date will vary from 0% to 200% of the number of PSU’s granted, depending on the achievement of performance criteria set by the Board of Directors. Vesting, and therefore the liability, is based on the estimated probability of achieving the performance criteria. The fair value of a PSU is estimated based on the quoted market price of the Company's common shares price and the number of PSU's estimated to be issued is dependent upon the estimated probability of achieving the performance criteria. The initial fair value of the liability is calculated as of the grant date and is recognized as share-based compensation expense over the vesting period in accordance with the vesting terms and conditions. Subsequently, at each reporting date and on settlement, the liability is re-measured with any changes in fair value recorded to the statement of earnings (loss). Deferred share units (“DSU’s”) DSU’s are granted to independent directors of the Company and are settled in cash when the individual ceases to be a director of the Company, either voluntarily or involuntarily. DSU’s vest immediately on the grant date. The fair value of a DSU reflects the value of a Company common share based on the quoted market price. The initial fair value of the liability is calculated as of the grant date and is recognized as share-based compensation expense. Subsequently, at each reporting date and on settlement, the liability is re-measured with any changes in fair value recorded to the statement of earnings (loss). Income and mining taxes Income taxes include Canadian federal and provincial income taxes. Provincial mining taxes represent Canadian provincial taxes levied on mining operations. To the extent these taxes are determined based on a measure of taxable earnings, they are also accounted for as income taxes. Income tax is recognized in earnings (loss) except to the extent that it relates to items recognized directly in equity, in which case it is recognized in equity. Current tax expense is the expected tax payable on the taxable earnings for the year, using tax rates enacted or substantively enacted at year end, adjusted for amendments to tax payable with regards to previous years. Deferred tax is provided for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Temporary differences are not provided for the initial recognition of assets or liabilities that affect neither accounting nor taxable earnings. The amount of deferred tax provided is based on the expected manner of realization or settlement of the carrying amount of assets and liabilities, using tax rates at the end of the reporting year applicable to the year of expected realization. A deferred tax asset is recognized only to the extent that it is probable that future taxable earnings will be available against which the asset can be utilized. Contingent liabilities Contingent liabilities are possible obligations whose existence will only be confirmed by future events not wholly within the control of the Company. Contingent liabilities are disclosed unless the possibility of an outflow of economic resources is considered remote. Earnings (loss) per share The Company presents basic earnings (loss) per share data, calculated by dividing the earnings (loss) attributable to common shareholders of the Company by the weighted average number of common shares outstanding during the year. Diluted earnings (loss) per share is determined by adjusting the earnings (loss) attributable to common shareholders and the weighted average number of common shares outstanding for the effects of all dilutive potential common shares.

CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS
CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS	4. CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS The preparation of financial statements requires the use of accounting estimates. It also requires management to exercise judgment in the process of applying its accounting policies. Estimates and judgments are regularly evaluated and are based on management’s experience and other factors, including expectations about future events that are believed to be reasonable under the circumstances. The following discusses the most significant accounting judgments and accounting estimates that the Company has made in the preparation of the financial statements that could result in a material effect in the next twelve months on the carrying amounts of assets and liabilities. Key accounting policy judgment Impairment of mineral properties, plant and equipment The application of the Company’s accounting policy for impairment of mineral properties, plant and equipment requires judgment to determine whether indicators of impairment exist. The review of impairment indicators includes consideration of both external and internal sources of information, including factors such as market and economic conditions, metal prices and forecasts, capital expenditure requirements, future operating costs and production volumes. Management has assessed impairment indicators for the Company’s mineral properties, plant and equipment and has concluded that no impairment indicators exist as of December 31, 2020. As at March 31, 2020, management assessed impairment indicators for the Company's mineral properties, plant and equipment and concluded that due to a decrease in the estimated total contained ounces in the updated mineral reserves of the Brucejack Mine, an indicator of impairment existed. Refer to note 8c for further details related to the impairment assessment. Impairment of exploration and evaluation assets The application of the Company’s accounting policy for impairment of exploration and evaluation assets requires judgment to determine whether indicators of impairment exist including factors such as the period for which the Company has the right to explore, expected renewals of exploration rights, whether substantive expenditures on further exploration and evaluation of resource properties are budgeted and evaluation of the results of exploration and evaluation activities up to the reporting date. Management assessed impairment indicators for the Company’s exploration and evaluation assets and has concluded that no impairment indicators exist as of December 31, 2020. Sources of estimation uncertainty Mineral reserves and mineral resources The Company estimates its mineral reserves and mineral resources based on information compiled and reviewed by qualified persons as defined in accordance with NI 43-101 requirements. The estimation of mineral reserves and mineral resources requires judgment to interpret available geological data, select an appropriate mining method and establish an extraction schedule. It also requires assumptions about future commodity prices, exchange rates, production costs, capital costs and recovery rates. There are uncertainties inherent in estimating mineral reserves and mineral resources and assumptions that are valid at the time of estimation and may change significantly when new information becomes available. New geological data as well as changes in the above assumptions may change the economic status of mineral reserves and may, ultimately, result in the mineral reserves being revised. The changes in the proven and probable mineral reserves announced on March 9, 2020 impacted the calculation of depreciation and depletion expense beginning in the first quarter of 2020. Recoverable amount of the Brucejack Mine At March 31, 2020, the Company identified an indicator of impairment for the Brucejack Mine CGU. For the impairment assessment completed at March 31, 2020, the recoverable amount of the Brucejack Mine CGU was determined based on the FVLCD method using the discounted cash flow model. The estimates used by management in arriving at the recoverable amount are subject to various risks and uncertainties and include the following estimates: mineral reserves, production profile, operating costs, capital costs, commodity prices, foreign exchange rates and discount rate. Changes in estimates could affect the expected recoverability of the Brucejack Mine. Refer to note 8c for further details related to the impairment assessment.

NEW ACCOUNTING STANDARDS AND RECENT PRONOUNCEMENTS	5. NEW ACCOUNTING STANDARDS AND RECENT PRONOUNCEMENTS New accounting standards, amendments and interpretations not yet adopted The following standards, amendments and interpretations have been issued but are not yet effective: · The IASB issued an amendment to IAS 16, Property, Plant and Equipment to prohibit the deducting from mineral properties, plant and equipment amounts received from selling items produced while bringing an asset into the location and condition necessary for it to be capable of operating in the manner intended by management. The amendment will require sales proceeds and related costs to be recognized in the statement of earnings (loss). The amendment is effective for annual reporting periods beginning on or after January 1, 2022, with earlier application permitted. This amendment is not expected to have a material impact on the Company. · The IASB issued " Interest Rate Benchmark Reform - Phase 2 (Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16) " with amendments that address issues that might affect financial reporting after the reform of an interest rate benchmark, including its replacement with alternative benchmark rates. The amendments are effective for annual reporting periods beginning on or after January 1, 2021. This amendment is not expected to have a material impact on the Company. There are no other IFRS standards or International Financial Reporting Interpretations Committee interpretations that are not yet effective or early adopted that are expected to have any impact on the Company. Accounting policy changes not yet adopted Effective January 1, 2021, the Company will adopt a voluntary change in its accounting policy for exploration and evaluation expenditures. The Company will recognize these costs as exploration and evaluation expenses in the statement of earnings (loss) in the period incurred until management concludes the technical feasibility and commercial viability of a mineral deposit. Costs that represent the acquisition of rights to explore a mineral deposit will continue to be capitalized. Prior to January 1, 2021, all exploration and evaluation expenditures were capitalized as exploration and evaluation assets. Management believes this change in accounting policy will result in a preferable policy that is better aligned with IFRS, with respect to what constitutes an asset and more consistent with its peer group. The Company will adopt the change in accounting policy retrospectively and restate balances for comparative periods. The Company will reclassify all post acquisition exploration and evaluation expenditures that have been capitalized to mineral properties, plant and equipment prior to the demonstration of technical feasibility and commercial viability. Initial acquisition costs of the Brucejack Mine and the Snowfield Property (“Snowfield”) are unaffected by the change in policy. The change in policy will materially affect the opening deficit and accumulated other comprehensive loss as of January 1, 2019, mineral properties, exploration and evaluation assets, depreciation and depletion included in inventories, cost of sales, loss on sale of exploration and evaluation asset and deferred income taxes. The Company is still in the process of quantifying the impact of the change in accounting policy for each of the periods affected.

(b) Exploration and evaluation assets Exploration and evaluation assets consist of regional drilling and exploration work on the Bowser Claims and the Porphyry Potential Deep Drilling Project. Sale of Snowfield On December 4, 2020, the Company sold Snowfield to KSM Mining ULC ("KSM"), a wholly owned subsidiary of Seabridge Gold Inc. Under the terms of the property purchase agreement, consideration received by the Company comprised of the following: · $100,000 in cash, which was received on December 16, 2020; · a 1.5% net smelter royalty in respect of all production from Snowfield; and · a $20,000 contingent cash payment payable within 6 months following the earlier of: o commencement of commercial production from Snowfield, or any part of Snowfield; and o the announcement by KSM (or a parent company) of the completion of a bankable feasibility study which includes production of mineral reserves from Snowfield. KSM is entitled to deduct and offset $15,000 of the contingent cash payment against amounts payable to the Company under the net smelter royalty. Due to uncertainty of commencement of commercial production from Snowfield or completion of a bankable feasibility study including Snowfield, the Company has determined the fair values of the net smelter royalty and contingent cash payment to be negligible amounts. At the time of sale, the carrying amount of Snowfield was $232,149. As a result, the transaction resulted in a loss on sale of exploration and evaluation asset in the amount of $132,149 which is recorded in the statement of earnings (loss). (c) Impairment assessment of Brucejack Mine At March 31, 2020, the Company reviewed impairment indicators for the Brucejack Mine and concluded there was an indicator of impairment due to a decrease in the estimated total contained ounces in the updated mineral reserves. In accordance with the Company’s accounting policy and IFRS, the recoverable amount was assessed as the higher of its value in use or FVLCD. The recoverable amount was determined based on the FVLCD method using the discounted cash flow model. The Brucejack Mine CGU includes mineral properties, plant and equipment, construction in progress, ROU assets, decommissioning and restoration provision and working capital. The carrying amount of the CGU at March 31, 2020 was $1,221,048. In arriving at FVLCD, discounted cash flows were estimated using the following significant assumptions: (a) the latest mineral reserves; (b) production profile, operating costs and capital costs from the latest detailed life of mine plan; (c) a gold price of $1,550 per ounce; (d) a silver price of $17.00 per ounce; (e) a foreign exchange rate of C$1.00:US$0.760; and (f) a real discount rate of 5.5%. The Company’s assessment of FVLCD exceeded the carrying amount of the Brucejack Mine CGU and as a result, no impairment loss was recognized in the statement of earnings (loss). (d) ROU assets As at December 31, 2020, the Company’s ROU assets consisted of the following: ROU asset ROU asset ROU asset Mobile equipment Buildings Other Total Cost Balance - January 1, 2019 $ 10,213 $ 2,509 $ 57 $ 12,779 Additions 2,136 3,115 1,245 6,496 Transfer from construction in progress to ROU assets 25 — — 25 Balance - December 31, 2019 $ 12,374 $ 5,624 $ 1,302 $ 19,300 Accumulated depreciation and depletion Balance - January 1, 2019 $ 42 $ — $ — $ 42 Depreciation and depletion 4,247 1,032 96 5,375 Balance - December 31, 2019 $ 4,289 $ 1,032 $ 96 $ 5,417 Net book value - December 31, 2019 $ 8,085 $ 4,592 $ 1,206 $ 13,883 Cost Balance - December 31, 2019 $ 12,374 $ 5,624 $ 1,302 $ 19,300 Additions 399 65 213 677 Transfer from construction in progress to ROU assets 39 — — 39 Lease modifications (425) — (57) (482) Balance - December 31, 2020 $ 12,387 $ 5,689 $ 1,458 $ 19,534 Accumulated depreciation and depletion Balance - December 31, 2019 $ 4,289 $ 1,032 $ 96 $ 5,417 Depreciation and depletion 4,108 1,151 139 5,398 Lease modifications — — (27) (27) Balance - December 31, 2020 $ 8,397 $ 2,183 $ 208 $ 10,788 Net book value - December 31, 2020 $ 3,990 $ 3,506 $ 1,250 $ 8,746 The Company is a party primarily to lease contracts for mining related mobile equipment and buildings.

The loan facility consisted of a $250,000 senior secured amortizing non-revolving credit facility (the “term facility”) and a $230,000 senior secured revolving credit facility (the “revolving facility”). In 2019, the Company reduced the size of the revolving facility to $200,000 as required by the terms of the loan facility. The loan facility is secured by substantially all of the assets of the Company and its subsidiaries. The term of the loan facility is four years, maturing on December 18, 2022. The undrawn portion of the loan facility at December 31, 2020 was $160,351 with $1,649 (C$2,100) used for a letter of credit supporting a reclamation deposit requirement. Each borrowing under the term and revolving facilities is available by way of USD London Inter-Bank Offered Rate (“LIBOR”) loans or USD base rate loans. The revolving facility is also available in Canadian prime loans, bankers’ acceptances, bankers’ acceptance equivalent loans, and letters of credit. Borrowings comprising USD LIBOR loans bear interest at LIBOR plus an applicable margin of 2.5% to 3.5% based on the Company’s net leverage ratio. Borrowings comprising USD base rate loans bear interest at the administrative agent’s base rate plus an applicable margin of 1.5% to 2.5% based on the Company’s net leverage ratio. For the year ended December 31, 2020, $12,839 (2019 – $24,056) of interest expense was expensed as interest and finance expense in the statement of earnings (loss). The term facility is required to be repaid in equal installments of principal until maturity. The Company has paid four quarterly installments on the term facility in the aggregate amount of $66,667 (2019 – 50,000), reducing the outstanding balance on the term facility to $133,333 as at December 31, 2020. During the second quarter of 2020, to increase available liquidity due to COVID-19, the Company drew down $16,000 of the available revolving facility. During the fourth quarter of 2020, the Company made a voluntary principal repayment on the revolving facility in the amount of $160,000 reducing the outstanding balance on the revolving facility to $38,000 as at December 31, 2020. Any amounts due under the revolving facility are required to be repaid in full on the maturity date. Any unused portion of the revolving facility is subject to an annual standby fee. Unamortized transaction costs associated with the term facility were $3,243 (2019 – $3,243) and the revolving facility were $4,639 (2019 – $4,639). The transactions costs have been recorded as a loan discount and will be amortized over the term of the loan. For the year ended December 31, 2020, $3,788 (2019 – $1,989) of amortization of the loan facility transaction costs were expensed to interest and finance expense in the statement of earnings (loss). The effective interest rate for the loan facility as at December 31, 2020 is 3.6%. The Company is subject to financial covenants under the terms of the loan facility including a minimum interest coverage ratio, a maximum leverage ratio, a minimum tangible net worth covenant and a minimum liquidity covenant. As at December 31, 2020, the Company was compliant with all financial and non-financial covenants. (b) On February 14, 2017, the Company completed an offering of $100,000 aggregate principal amount of unsecured convertible senior subordinated notes due 2022 (the “Notes”) which mature on March 15, 2022 and bear an interest rate of 2.25% per annum, payable semi-annually in arrears on March 15 and September 15 of each year. The Notes are convertible into common shares of the Company at a fixed conversion rate, subject to certain anti-dilution adjustments. In addition, if certain fundamental changes as defined in the note indenture occur, holders of the Notes may be entitled to an increased conversion rate. The Notes are convertible into common shares of the Company at an initial conversion rate of 62.5 common shares per $1 principal amount of Notes converted, representing an initial conversion price of $16.00 per common share. The Company may redeem all or part of the Notes for cash, but only if the last reported sale price of the Company’s common shares for 20 or more trading days in a period of 30 consecutive trading days exceeds 130% of the conversion price. The redemption price will equal to the sum of (a) 100% of the principal amount of the notes to be redeemed and (b) accrued and unpaid interest, if any, to the redemption date. The Company is required to offer to purchase for cash all of the outstanding Notes upon a fundamental change, at a purchase price in cash equal to 100% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest, if any, to the fundamental change purchase date. At initial recognition, the net proceeds of the Notes were bifurcated into its debt and equity components of $71,685 and $24,110 ($17,603 net of deferred tax) respectively. The fair value of the debt portion was estimated using a discounted cash flow model method based on an expected life of five years and a discount rate of 8.6%. The debt portion has been classified a financial liability at amortized cost and is recorded net of transaction costs and accreted over the expected life using the effective interest rate of 7.8%. For the year ended December 31, 2020, $5,584 (2019 – $5,568) of accretion of convertible notes was expensed as interest and finance expense in the statement of earnings (loss). (c) Offtake obligation In September 2015, the Company entered into an agreement pursuant to which it would deliver 100% of refined gold up to 7,067,000 ounces. The final purchase price to be paid by the purchaser would be, at the purchaser's option, a market referenced gold price in USD per ounce during a defined pricing period before and after the date of each sale. The Company had the option to reduce the offtake obligation by up to 75% by paying $13 per ounce effective December 31, 2019 on the then remaining undelivered gold ounces. On September 15, 2019, the Company entered into an agreement with the holders of the offtake obligation to repurchase 100% of the outstanding obligation effective September 30, 2019. In exchange, the Company agreed to pay the holders of the offtake obligation $13 per ounce for 100% of the refined gold remaining to be delivered under the offtake agreement, equating to $82,416. Under the terms of the agreement, the Company paid $62,416 on September 30, 2019 and $20,000 on November 30, 2019. For the year ended December 31, 2019, the Company delivered 234,378 ounces of gold under the offtake agreement. Of the amount settled, the Company physically delivered 158,268 ounces from doré production and purchased 76,110 ounces to satisfy delivery of gold produced from concentrate sales. The settlement of the gold ounces resulted in a decrease in the offtake obligation to the date of repurchase of $3,068. Until the repurchase of the offtake agreement on September 30, 2019, the offtake obligation was recorded at fair value at each statement of financial position date. For the year ended December 31, 2019, the change in fair value of the offtake obligation to the date of repurchase was a fair value loss of $15,415.

DECOMMISSIONING AND RESTORATION PROVISION	11. DECOMMISSIONING AND RESTORATION PROVISION (a) Reclamation bonds The Company has $55 of restricted cash (2019 - $54) in the form of Guaranteed Investment Certificates as security deposits with various government agencies in relation to decommissioning and restoration provisions of the Brucejack Mine. In support of the closure plan for the Brucejack Mine, the Company holds total surety bonds of C$31,700 in favour of the Ministry of Energy and Mines. (b) Decommissioning and restoration provision The Company has a liability for remediation of current and past disturbances associated with the exploration, development and production activities at the Brucejack Mine. The decommissioning and restoration provision is as follows: For the year ended December 31, December 31, 2020 2019 Opening balance $ 21,239 $ 18,947 Change in amount and timing of cash flows 2,812 (133) Change in discount rate 1,643 2,028 Accretion of decommissioning and restoration provision 262 446 Settlement of decommissioning and restoration provision — (49) Ending balance $ 25,956 $ 21,239 For the year ended December 31, 2020, the provision increased due to an increase in estimated costs to reclaim the Brucejack Mine and a decrease in the discount rate. The Company used an inflation rate of 1.6% (2019 – 1.7%) and a discount rate of 0.9% (2019 – 1.5%) in calculating the estimated provision. The liability for retirement and remediation on an undiscounted basis before inflation is $24,618 (C$31,344) (2019 - $21,086 (2019 – C$27,386)). Most of the expected expenditures to settle the decommissioning and restoration provision are anticipated to commence in 2033 after the end of the current mine life.

Such options can be exercisable for a maximum of five years from the date of grant. The exercise price of each share option is set by the Board of Directors at the time of grant but cannot be less than the then market price of common shares. The following table summarizes the changes in share options for the year ended December 31: 2020 2019 Weighted Weighted average average Number of exercise price Number of exercise price share options (in CAD) share options (in CAD) Outstanding, January 1, 3,468,310 $ 10.01 4,562,919 $ 9.47 Granted — — 140,000 14.07 Exercised (2,031,747) 8.85 (1,209,709) 8.39 Forfeited (308,022) 11.50 (19,800) 12.97 Expired (192,439) 12.38 (5,100) 12.97 Outstanding, December 31, 936,102 $ 11.53 3,468,310 $ 10.01 For options exercised during the year, the related weighted average share price at the time of exercise was C$13.59 (2019 – C$14.89).

The following are the weighted average assumptions employed to estimate the fair value of options granted for the year ended December 31, 2020 and 2019 using the Black-Scholes option pricing model: For the year ended December 31, December 31, 2020 2019 Risk-free interest rate N/A 1.43 % Expected volatility N/A 55.21 % Expected life N/A 5 years Expected dividend yield N/A Nil Option pricing models require the input of subjective assumptions including the expected price volatility and expected option life. Changes in these assumptions would have had a significant impact on the initial fair value calculation. (d) RSU's The Company has adopted a RSU plan to allow the Board of Directors to grant its employees and consultants, non-transferable share units based on the value of the Company’s share price at the date of grant. The awards have a graded vesting schedule over a three-year period and can be either cash or equity settled upon vesting at the discretion of the Board of Directors. The associated compensation cost is recorded in share-based compensation expense. The following table summarizes the changes in RSU’s for the year ended December 31: 2020 2019 Weighted Weighted Number of average fair Number of average fair RSU's value (in CAD) RSU's value (in CAD) Outstanding, January 1, 404,523 $ 14.44 741,886 $ 11.31 Granted 463,971 11.99 — — Settled (231,235) 14.32 (297,062) 13.54 Forfeited (224,894) 14.91 (40,301) 12.87 Outstanding, December 31, 412,365 $ 14.55 404,523 $ 14.44 At December 31, 2020, a liability of $2,535 (2019 – $2,887) was included in accounts payable and accrued liabilities. For the year ended December 31, 2020, $2,074 (2019 – $4,556) was expensed in the statement of earnings (loss) as share-based compensation expense. (e) PSU’s PSU’s are granted to senior management under the RSU plan. The PSU’s vest at the end of the third year and the number of units to be issued on the vesting date will vary from 0% to 200% of the number of PSU’s granted, depending on the achievement of performance criteria. The awards can be settled in cash or equity upon vesting at the discretion of the Board of Directors. The following table summarizes the changes in PSU’s for the year ended December 31: 2020 2019 Weighted Weighted Number of average fair Number of average fair PSU's value (in CAD) PSU's value (in CAD) Outstanding, January 1, 166,085 $ 14.44 166,085 $ 11.31 Granted 222,860 12.21 — — Settled (9,665) 14.71 — — Forfeited (278,308) 14.96 — — Outstanding, December 31, 100,972 $ 14.55 166,085 $ 14.44 At December 31, 2020, a liability of $231 (2019 – $924) was included in accounts payable and accrued liabilities. For the year ended December 31, 2020, due to forfeited PSU's in the year, a recovery of $678 (2019 – expense of $667) was recorded in the statement of earnings (loss) as share-based compensation expense. (f) DSU’s The Company has adopted a DSU plan for independent directors of the Company. Pursuant to the plan, eligible directors can elect to receive all or part of their total cash compensation in the form of DSU’s. The number of DSU’s granted to an eligible director is determined by dividing the portion of the compensation to be paid in DSU’s by the fair market value of the Company’s common shares on the grant date. In addition, the Board may, at its discretion, grant additional DSU’s to plan participants. Each eligible director will be required to hold DSU’s received until the eligible director ceases to be a director of the Company, following which the DSU’s will be settled in cash. The following table summarizes the changes in DSU’s for the year ended December 31: 2020 2019 Weighted Weighted Number of average fair Number of average fair DSU’s value (in CAD) DSU’s value (in CAD) Outstanding, January 1, 156,825 $ 14.45 117,587 $ 11.57 Granted 103,184 12.51 39,238 12.36 Outstanding, December 31, 260,009 $ 14.59 156,825 $ 14.45 At December 31, 2020, a liability of $2,980 (2019 – $1,745) was included in accounts payable and accrued liabilities. For the year ended December 31, 2020, $1,097 (2019 – $683) was expensed in the statement of earnings (loss) as share-based compensation expense. (g) Earnings (loss) per share The calculation of diluted earnings (loss) per share was based on earnings (loss) attributable to ordinary shareholders and the weighted-average number of shares outstanding after adjustments for the effect of potential dilutive shares. For the years ended December 31, 2020 and 2019, potential share issuances arising from the exercise of share options and the settlement of RSU’s and PSU's in common shares were included in the calculation of diluted weighted average shares outstanding as well as their impact on earnings (loss) attributable to shareholders of the Company. Potentially dilutive shares associated with the convertible notes, share options, RSU's and PSU's were not included in the diluted earnings (loss) per share calculation as their effect was anti-dilutive. The following table summarizes the calculation of basic and diluted earnings (loss) per share: For the year ended December 31, December 31, 2020 2019 Net (loss) earnings for the year $ (38,438) $ 40,917 Basic weighted average number of common shares outstanding 186,412,795 184,731,109 Effective impact of dilutive securities: Share options — 972,815 RSU's — 27,402 Diluted weighted average number of common shares outstanding 186,412,795 185,731,326 (Loss) earnings per share Basic $ (0.21) $ 0.22 Diluted $ (0.21) $ 0.22

FINANCIAL RISK MANAGEMENT

FINANCIAL RISK MANAGEMENT	12 Months Ended
	Dec. 31, 2020
FINANCIAL RISK MANAGEMENT
FINANCIAL RISK MANAGEMENT	19. FINANCIAL RISK MANAGEMENT Financial risk management The Company has exposure to a variety of financial risks: market risk (including currency risk, interest rate risk and commodity price risk), credit risk and liquidity risk from its use of financial instruments. This note presents information about the Company’s exposure to each of these risks, the Company’s objectives, policies and processes for measuring and managing risk, and the Company’s management of capital. Risk management is the responsibility of management and is carried out under the oversight of and policies approved by, the Board of Directors. Material risks are monitored and are regularly discussed with the Audit Committee and the Board of Directors. (a) Market risk Market risk is the risk that changes in market prices, such as foreign exchange rates, interest rates and commodity prices will affect the Company’s cash flows or value of its financial instruments. (i) Currency risk The Company is subject to currency risk on financial instruments which are denominated in currencies that are not the same as the functional currency of the entity that holds them. Exchange gains and losses would impact earnings (loss). The Company is exposed to currency risk through cash and cash equivalents, receivables and other excluding trade receivables, restricted cash and accounts payable and accrued liabilities which are denominated in CAD. The following table shows the impact on pre-tax earnings (loss) of a 10% change in the USD:CAD exchange rate on financial assets and liabilities denominated in CAD, as of December 31, 2020, with all other variables held constant: Impact of currency rate change on pre-tax earnings (loss) 10% increase 10% decrease Cash and cash equivalents $ 1,943 $ (1,943) Receivables and other, excluding trade receivables 178 (178) Restricted cash 5 (5) Accounts payable and accrued liabilities (5,869) 5,869 In addition to currency risk from financial instruments, a majority of the Company’s mine production costs, capital expenditures and corporate administrative costs are incurred in CAD. Consequently, fluctuations in the USD exchange rate against the CAD increases the volatility of cost of sales and corporate administrative costs. In 2020, the Company hedged a portion of its exposure to currency fluctuations using forward contracts. For the year ended December 31, 2020, the change in fair value of non-hedge derivatives resulted in a gain on financial instruments at fair value of $377 (2019 - nil). The Company has no foreign exchange forward contracts as of December 31, 2020. (ii) Interest rate risk The Company is subject to interest rate risk with respect to its investments in cash and cash equivalents. The Company’s current policy is to invest cash at floating rates of interest and cash reserves are to be maintained in cash and cash equivalents in order to maintain liquidity, while achieving a satisfactory return for shareholders. Fluctuations in interest rates when cash and cash equivalents mature impact interest income earned. The Company is subject to interest rate risk with respect to its loan facility. Interest rates associated with this facility are based on LIBOR and the administrative agents' base rate which fluctuate based on market conditions. The following table shows the impact on pre-tax earnings (loss) of a 1% change in interest rates on financial assets and liabilities as of December 31, 2020, with all other variables held constant: Impact of interest rate change on pre-tax earnings (loss) 1% increase 1% decrease Cash and cash equivalents $ 917 $ (917) Loan facility (315) 315 (iii) Commodity price risk The Company is subject to commodity price risk from fluctuations in the market prices for gold and silver. Commodity price risks are affected by many factors that are outside the Company’s control including global or regional consumption patterns, the supply of and demand for metals, speculative activities, the availability and costs of metal substitutes, inflation and political and economic conditions. The financial instruments impacted by commodity prices are trade receivables. Price adjustments are made in subsequent periods to the customer receivables for concentrate sales transactions based on movements in market prices prior to final settlement. As a result, concentrate sales receivables are fair valued and adjusted each period to reflect forward market prices to the estimated settlement date. For the years ended December 31, 2020 and 2019, the Company has not hedged the price of any commodity. The following table shows the impact of pre-tax earnings (loss) from changes in the fair values of financial instruments with a 10% change in gold and silver commodity prices. The impact of a 10% movement in commodity prices as of December 31, 2020, with all other variables held constant, is as follows: Impact of price change on pre-tax earnings (loss) 10% increase 10% decrease Trade receivables $ 9,677 $ (9,677) (b) Credit risk Credit risk is the risk of potential loss to the Company if the counterparty to a financial instrument fails to meet its contractual obligations. The Company's credit risk is primarily attributable to its financial assets including cash and cash equivalents, trade receivables and restricted cash. The carrying amount of financial assets represents the maximum credit exposure: December 31, December 31, 2020 2019 Cash and cash equivalents $ 174,753 $ 23,174 Trade receivables 8,377 6,210 Restricted cash 55 54 $ 183,185 $ 29,438 The Company limits its exposure to credit risk on financial assets through investing its cash and cash equivalents and restricted cash with high-credit quality financial institutions. Management believes the risk of loss related to these deposits to be low. The Company regularly evaluates changes in the status of its counterparties. The Company is exposed to credit risk through its trade receivables, which are principally with internationally recognized counterparties. The Company sells its refined gold on spot contracts to financial institutions in Canada and its concentrates to trading companies. The Company sells its silver to refineries located in Canada and other jurisdictions and trading companies. The Company has had limited instances of default from its counterparties. The Company regularly evaluates the counterparties to which it sells its product. The Company is not economically dependent on a limited number of customers for the sale of its gold and silver as its products can be sold through numerous world-wide commodity markets and traders. As at December 31, 2020, the Company has $8,377 (2019 – $6,210) receivables related to its gold and silver revenue. As these receivables are measured at FVTPL, expected credit losses are incorporated into the estimate of fair value. (c) Liquidity risk Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company manages liquidity risk by monitoring actual and projected cash flows and matching the maturity profile of financial assets and liabilities. Cash flow forecasting is performed regularly to ensure that there is sufficient liquidity in order to meet short-term business requirements, after taking into account cash flows from operations and our holdings of cash and cash equivalents. Cash and cash equivalents are currently invested in business and savings accounts with financial institutions of high credit quality which are available on demand. To the extent there is not sufficient liquidity in the form of cash and cash equivalents to meet obligations or to mitigate the impact of potential risks such as COVID-19, the Company will consider drawing on the revolving portion of the loan facility (to the extent available), or by securing additional debt and/or equity funding. The Company has issued surety bonds and letters of credit to support future decommissioning and restoration provisions. The Company’s financial obligations consist of accounts payable and accrued liabilities and long-term debt consisting of the loan facility and convertible notes. The maturity of financial liabilities as at December 31, 2020 is as follows: More than 1 year 2-3 years 4-5 years 5 years Total Principal repayments on loan facility $ 66,667 $ 104,667 $ — $ — $ 171,334 Convertible notes — 100,000 — — 100,000 Accounts payable and accrued liabilities 57,532 — — — 57,532 Interest payments on loan facility (1) 3,885 2,052 — — 5,937 Lease obligations 5,320 3,755 292 — 9,367 Interest on convertible notes 2,250 1,114 — — 3,364 RSU liability 1,634 1,132 — — 2,766 $ 137,288 $ 212,720 $ 292 $ — $ 350,300 (1) Interest payments on the loan facility represent management’s estimate based on current LIBOR and the Company’s projected applicable margin in accordance with the terms of the loan facility. Capital management The Company’s objectives in the managing of capital are to safeguard the ability to continue as a going concern and provide financial capacity to meet its strategic objectives. Management monitors the amount of cash and cash equivalents, debt instruments and equity in the capital structure and adjusts the capital structure, as necessary, to support the exploration, development and operation of its Brucejack Mine and projects. The capital structure of the Company consists of debt instruments and equity attributable to common shareholders, comprising of issued share capital, other reserves and deficit. To maintain or adjust the capital structure, the Company may issue new shares, issue new debt, acquire or dispose of assets to facilitate the management of its capital requirements. The Company prepares detailed annual budgets and cash flow forecasts for mining, development and corporate activities that are approved by the Board of Directors. Forecasts are regularly reviewed and updated for changes in circumstances to facilitate capital allocation, investment and financing decisions. Fair value estimation The Company’s financial assets and liabilities are measured and recognized according to a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities and the lowest priority to unobservable inputs. The three levels of fair value hierarchy are as follows: Level 1: Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices). Level 3: Inputs for the asset or liability that are not based on observable market data The carrying values of cash and cash equivalents, non-trade receivables and other, restricted cash and accounts payable and accrued liabilities approximate their fair values due to the short-term maturity of these financial instruments. The carrying value of the loan facility approximates fair value due to the floating rate basis of the interest charges and insignificant changes in credit risk. The carrying value of the debt portion of convertible note approximates its fair value. The following tables present the Company’s financial assets and liabilities by level within the fair value hierarchy. It does not include fair value information for financial assets and financial liabilities not measured at fair value if the carrying amount is a reasonable approximation of fair value.

CONTINGENCIES
CONTINGENCIES	22. CONTINGENCIES The Company is involved in various claims, litigation and other matters in the ordinary course and conduct of business. Some of these pending matters may take a number of years to resolve. While it is not possible to determine the ultimate outcome of such actions at this time, and inherent uncertainties exist in predicting such outcomes, it is the Company’s belief that the ultimate resolution of such actions is not reasonably likely to have a material adverse effect on its consolidated financial position or results of operations. (a) Canadian class action On October 29, 2013, David Wong, a shareholder of the Company, filed a proposed class action claim (the "Wong Action") against the Company, Robert Quartermain (a director, and the President and CEO of the Company at such time) and Snowden Mining Industry Consultants Ltd. (“Snowden”). The Wong Action was filed in the Ontario Superior Court of Justice. The Wong Action alleges that the price of the Company's shares on the TSX and NYSE suffered a significant drop in value following the announcement on October 9, 2013 of the resignation of Strathcona Mineral Services Ltd. (“Strathcona”), the consultant responsible for overseeing and reporting on the 10,000-tonne bulk sample, and the announcement of Strathcona’s reasons for resigning on October 22, 2013. The Wong Action claims C$60,000 in general damages on behalf of a class of persons who acquired the Company’s securities between July 23, 2013 and October 21, 2013. Snowden is no longer a defendant in the Wong Action. The plaintiff in the Wong Action brought a motion for leave to commence an action under the secondary market provisions in Part XXIII.1 of the Ontario Securities Act. The motion was heard on May 29 and 30, 2017. The Court allowed the plaintiff’s motion on July 20, 2017. The Company was denied leave to appeal this decision. The Company and Robert Quartermain consented to, and on January 23, 2019 the Court granted, an order certifying the Wong Action as a class proceeding pursuant to the Class Proceedings Act (Ontario). In 2020, the plaintiff brought a motion to amend the statement of claim to plead additional misrepresentations. On July 22, 2020, the Court refused to permit these new allegations. The plaintiff appealed this refusal to the Court of Appeal for Ontario, and subsequently abandoned this appeal on February 18, 2021. On December 7 and 8, 2020, the Court heard the Company’s and Robert Quartermain’s motion for summary judgment to dismiss the Wong Action and the plaintiff’s cross-motion for summary judgment to allow the Wong Action. On February 2, 2021 the Court allowed the defendants’ motion for summary judgment, dismissed the plaintiff’s cross-motion for summary judgment, and dismissed the Wong Action. The Court ruled that the Company did not make a misrepresentation in its continuous disclosure and that, in any event, the defendants were relieved of liability on the basis that they conducted a reasonable investigation pursuant to section 138.4(6) of the Ontario Securities Act. The plaintiff has until March 4, 2021 to appeal the Court’s decision. The Company believes that the allegations made against it in the Wong Action are meritless and it will continue to vigorously defend them, although no assurance can be given with respect to the ultimate outcome. The Company has not accrued any amounts for this action. (b) United States class action Two putative class action complaints were filed against the Company and certain of its officers in the United States District Court for the Southern District of New York, one on September 7, 2018 and the other on October 19, 2018. The complaints were filed on behalf of an alleged class of all persons and entities who purchased or acquired shares of the Company between July 21, 2016 and September 6, 2018, and relate to public disclosures of the Company made between July 2016 and September 2018 regarding the Brucejack Mine. On April 8, 2019, the United States District Court for the Southern District of New York issued an order granting Aurico Gold Fund LP’s motion to consolidate the two cases under the case caption "In re Pretium Resources, Inc. Securities Litigation" (the “Aurico Action”), appoint itself as lead plaintiff, and approve lead plaintiff’s selection of counsel. On June 21, 2019, the plaintiffs in the Aurico Action filed a Consolidated Amended Class Action Complaint. The Company retained legal counsel in connection with these matters and on August 27, 2019, filed its memorandum of law in support of its motion to dismiss the Aurico Action. The plaintiffs filed their opposition to the Company's motion to dismiss on October 28, 2019 and the Company filed its reply brief on December 10, 2019. On February 27, 2020, the District Court granted the Company's motion to dismiss the Aurico Action but allowed the plaintiffs to move for leave to amend their complaint within 30 days of the order. The plaintiffs in the Aurico Action filed their motion to amend their complaint on March 30, 2020. The Company's memorandum of law in opposition to the plaintiff's motion for leave to amend complaint was filed on April 13, 2020 and the plaintiffs filed their reply memorandum on April 20, 2020. On July 9, 2020, the District Court denied the plaintiffs' motion to amend their complaint. The deadline for the plaintiffs to appeal the District Court's dismissal of the motion to amend their complaint passed in August 2020 without an appeal being filed. As a result, this matter is now concluded. (c) Construction claims On April 24, 2017, Bear Creek Contracting Ltd. (“Bear Creek”) filed a Notice of Civil Claim against the Company (the “Bear Creek Action”) alleging that the Company owes Bear Creek C$14,563 in general damages in connection with work undertaken at the Brucejack Mine transmission line. The Bear Creek Action was filed in the Supreme Court of BC. The Company filed a Response to Civil Claim on July 31, 2017, opposing all of the claims and allegations made. Notices of Civil Claim have also been filed by Blue Max Drilling Inc. (April 24, 2017), More Core Diamond Drilling Services Ltd. (March 27, 2017), and Lakelse Air Ltd. (February 23, 2018) who were subcontractors working under Bear Creek. Responses to Civil Claim have been filed in those actions and the claims are understood to be subsumed in the amount claimed by Bear Creek. In October 2020, the Supreme Court of BC partially allowed an application from Bear Creek to add parties to the Bear Creek Action and amend its pleadings, including with respect to the Company. The Company is of the view that any liability it may have is within the limits of the lien holdback it continues to hold in trust with respect to these claims. The Company believes that all other allegations made against it in the Bear Creek Action, and the other actions, are meritless and will vigorously defend the matter, although no assurance can be given with respect to the ultimate outcome of such proceedings. The Company has not accrued any amounts for any of the actions.

SUBSEQUENT EVENTS	23 . SUBSEQUENT EVENTS On February 10, 2021, a COVID-19 outbreak was verbally declared at the Brucejack Mine by the BC Northern Health Medical Health Officer. To protect the health and safety of the Company’s workforce and local communities, the Company implemented enhanced outbreak protocols which included restrictions on travel to and from the Brucejack Mine camp while site wide testing was conducted and an assessment by BC Northern Health could be completed. At the Brucejack Mine camp, 453 tests were conducted and based on those results, it was determined that the large majority of positive cases were restricted to a limited cluster. On February 17, 2021, it was announced that travel restrictions had been lifted with additional protocols and procedures developed in collaboration with local indigenous partners and BC Northern Health. These protocols include rigorous testing of all employees and contractors. Throughout the outbreak, mine and mill production continued. The Company is assessing the potential impact on operations and will continue to closely monitor the situation and provide updates as appropriate. Currently, the Company is managing cases of COVID-19 among employees and contractors at the Brucejack Mine. All are in isolation, remain in good health and have exhibited limited symptoms. In partnership with BC Northern Health, contact tracing was undertaken to determine the potential for additional exposures. Close contacts, identified through the tracing process, have been notified and moved into isolation. Isolation protocols will remain in effect for the duration established by BC Northern Health, with regular monitoring for COVID-19 symptoms. The Company established COVID-19 management plans and implemented enhanced protocols and preventative measures to mitigate the spread of COVID-19 at the onset of the pandemic to protect the well-being of its employees, contractors, their families, local communities and other stakeholders. The Company continues to follow the stringent COVID-19 infection prevention guidance and directives of federal, provincial and regional authorities in respect of general and mine site-specific protocols and is working in close partnership with its medical service provider and BC Northern Health.

SIGNIFICANT ACCOUNTING POLICIES
Basis of consolidation	Basis of consolidation These consolidated financial statements include the financial statements of the Company and the entities controlled by the Company, its subsidiaries, listed in the following table: Name of subsidiary Place of Proportion of Principal activity Pretium Exploration Inc. BC, Canada 100% Operates the Brucejack Mine 0890696 BC Ltd. BC, Canada 100% Holds real estate in Stewart, BC Control is defined as the exposure, or rights, to variable returns from involvement with an investee and the ability to affect those returns through power over the investee. Power over an investee exists when the Company has existing rights that give the Company the ability to direct the activities that significantly affect the investee’s returns. This control is generally evidenced through owning more than 50% of the voting rights or currently exercisable potential voting rights of a subsidiary’s share capital. The financial statements of subsidiaries are included in the consolidated financial statements from the date that control commences until the date that control ceases. Intercompany balances and transactions, including any unrealized income and expenses arising from intercompany transactions, are eliminated in preparing the consolidated financial statements.
Foreign currency translation	Foreign currency translation Functional and presentation currency Items included in the financial statements of each consolidated entity are measured using the currency of the primary economic environment in which the entity operates (the “functional currency”). The functional currency of the Company and its subsidiaries is the United States dollar (“USD”), which is also the Company’s presentation currency. References to “$” or “USD” are to United States dollars, while references to “C$” or “CAD” are to Canadian dollars. Transactions and balances Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions or valuations where items are re-measured. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at period end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the statement of earnings (loss) for the year.
Financial instruments	Financial instruments Financial assets – Classification Financial assets are classified at initial recognition as either: measured at amortized cost, FVTPL or fair value through other comprehensive income (“FVOCI”). The classification depends on the Company’s business model for managing the financial assets and the contractual terms which give rise to the cash flows. For assets measured at fair value, gains and losses will either be recorded in earnings (loss) or other comprehensive income (“OCI”). For investments in debt instruments, this will depend on the business model for which the investment is held. For investments in equity instruments that are not held for trading, this will depend on whether the Company has made an irrevocable election at the time of initial recognition to account for the equity investment at FVOCI. The Company reclassifies debt investments when and only when its business model for managing those assets changes. Financial assets – Measurement At initial recognition, the Company measures a financial asset at its fair value plus, in the case of a financial asset not at FVTPL, transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at FVTPL are expensed in the statement of earnings (loss). Financial assets with embedded derivatives are considered in their entirety when determining whether their cash flows are solely payment of principal and interest. Subsequent measurement of debt instruments depends on the Company’s business model for managing the asset and the cash flow characteristics of the asset. There are three measurement categories into which the Company classifies its debt instruments: · Amortized cost – Assets that are held for collection of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortized cost. A gain or loss on a debt investment that is subsequently measured at amortized cost and is not part of a hedging relationship is recognized in earnings (loss) when the asset is derecognized or impaired. Interest income from these financial assets is included in interest and finance income using the effective interest rate method. · FVOCI – Assets that are held for collection of contractual cash flows and for selling the financial assets, where the assets cash flows represent solely payments of principal and interest, are measured at FVOCI. Movements in the carrying amount are taken through OCI, except for the recognition of impairment gains or losses, interest income and foreign exchange gains and losses which are recognized in earnings (loss). When the financial asset is derecognized, the cumulative gain or loss previously recognized in OCI is reclassified from equity to earnings (loss) and recognized in other gains (losses). Interest income from these financial assets is included in interest and finance expense using the effective interest rate method. Foreign exchange gains and losses are presented in foreign exchange gain (loss) and impairment expenses in other expenses. · FVTPL – Assets that do not meet the criteria for amortized cost or FVOCI are measured at FVTPL. A gain or loss on a debt investment that is subsequently measured at FVTPL and is not part of a hedging relationship is recognized in earnings (loss) and presented net in the statement of earnings (loss) within other gains (losses) in the period in which it arises. Changes in the fair value of financial assets at FVTPL are recognized in gain (loss) on financial instruments at fair value in the statement of earnings (loss) as applicable. Cash and cash equivalents and restricted cash Cash and cash equivalents comprise cash holdings in business and savings accounts held at major financial institutions with an original maturity date of three months or less. Restricted cash is held at major financial institutions as collateral for reclamation bonds. Cash and restricted cash are classified at amortized cost. Interest income is recognized by applying the effective interest rate method. Receivables and other The Company’s trade receivables result from sales transactions in accordance with IFRS 15, Revenue from Contracts with Customers and contain provisional pricing arrangements. These trade receivables are classified as FVTPL with the gain (loss) included in revenue. Accounts payable and accrued liabilities and debt Accounts payable and accrued liabilities, the debt portion of the convertible notes and the senior secured loan facility are recognized initially at fair value, net of any directly attributable transaction costs. Subsequent to initial recognition these financial liabilities are held at amortized cost using the effective interest method. Derivatives Derivative instruments, including embedded derivatives in financial liabilities or non-financial contracts, such as the offtake obligation, and non-hedge derivatives, such as foreign exchange contracts, are recorded at FVTPL and, accordingly, are recorded on the statement of financial position at fair value. Fair values for derivative instruments are determined using valuation techniques, with assumptions based on market conditions existing at the statement of financial position date. Changes in fair value at each reporting date are included in the statement of earnings (loss) as gain (loss) on financial instruments at fair value.
Inventories	Inventories Ore stockpiles, in-circuit and finished metal inventory (gold and silver) are valued at the lower of weighted average production cost and net realizable value. Production costs include the cost of raw materials, direct labour, mine-site overhead expenses and applicable depreciation and depletion of mineral properties, plant and equipment. Net realizable value is calculated as the estimated price at the time of sale based on prevailing and long-term metal prices less estimated future production costs to convert the inventories into saleable form and estimated costs to sell. Ore stockpile inventory represents mined ore on the surface or underground that is available for further processing. In-circuit inventory represents material in the mill circuit that is in the process of being converted into a saleable form. Finished metal inventory represents gold and silver doré and concentrate located at the mine, in transit to customers and at refineries. Materials and supplies inventories are valued at the lower of weighted average cost and net realizable value. Replacement costs of materials and spare parts are generally used as the best estimate of net realizable value. Any write-downs of inventory to net realizable value are recorded within cost of sales in the statement of earnings (loss). If there is a subsequent increase in the value of inventory, the previous write-downs to net realizable value are reversed up to cost to the extent that the related inventory has not been sold.
Mineral properties	Mineral properties Mineral properties are measured at cost less accumulated depletion and accumulated impairment losses. Mineral properties include the fair value attributable to mineral reserves and mineral resources acquired in a business combination or asset acquisition, mine development costs and previously capitalized exploration and evaluation costs. Upon commencement of production, a mineral property is depleted using the unit-of-production method. Unit-of-production depletion rates are determined using gold ounces mined over the estimated proven and probable mineral reserves of the mine.
Development costs incurred during production	Development costs incurred during production The Company incurs development costs to build new raises and ramps (vertical development) that enable the Company to physically access ore underground. The time over which these costs will be incurred depends on the mine life. These underground development costs are capitalized as incurred. Capitalized underground development costs incurred to enable access to specific areas of the mine and which only provide an economic benefit over a specific period of mining are depleted using a unit-of-production method determined using gold ounces mined over the estimated proven and probable mineral reserves in that particular area of the mine.
Plant and equipment	Plant and equipment Plant and equipment are measured at cost less accumulated depreciation and accumulated impairment losses. The initial cost of an asset is comprised of its purchase price or construction cost, any costs directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management and the estimated future cost of dismantling and removing the asset at the end of its useful life. The purchase price or construction cost is the fair value of consideration to acquire the asset. Depreciation of plant and equipment commences when the asset has been fully commissioned and is available for its intended use. A majority of mine and site infrastructure assets, including buildings, roads and transmission lines are depreciated using a unit-of-production method over the life of mine. Depreciation is determined using gold ounces mined over the estimated proven and probable mineral reserves of the mine. The Company reviews estimated proven and probable mineral reserves annually and when facts and circumstances indicate that a review should be performed. Changes to estimated proven and probable mineral reserves are accounted for prospectively. Depreciation of other assets, including those ancillary to the mine are calculated using the straight-line method to allocate cost over the estimated useful lives, as follows: Asset class Estimated useful life Mine and mill equipment 5 - 13 years Light vehicles 3 - 5 years Office and computer equipment 3 - 5 years Leasehold improvements Term of lease When significant components of an asset have different useful lives, depreciation is calculated on each separate component. Each asset or component’s estimated useful life has due regard to both its own physical life limitations and the present assessment of economically recoverable mineral reserves of the Brucejack Mine. Depreciation methods and estimated useful lives and residual values are reviewed annually and when facts and circumstances indicate that a review should be performed. Changes in estimates are accounted for prospectively. Expenditures on major maintenance or repairs includes the cost of an asset’s replacement parts and overhaul costs. Where an asset or part of an asset is replaced, and it is probable that future economic benefits associated with the item will be available to the Company, the expenditure is capitalized and the carrying amount of the item replaced is derecognized. Similarly, overhaul costs associated with major maintenance are capitalized and depreciated over their useful lives where it is probable that the future economic benefits will be available and any remaining carrying amounts of the cost of previous overhauls are derecognized. All other costs are expensed as incurred. An item of plant and equipment is derecognized upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. Any gain or loss arising on disposal of the asset, determined as the difference between the net disposal proceeds and the carrying amount of the asset, is recognized in the statement of earnings (loss).
Construction in progress	Construction in progress Costs recorded for assets under construction are capitalized as construction in progress. On completion, the cost of construction is transferred to the appropriate category of mineral properties, plant and equipment. No depreciation is recorded until the assets are substantially complete and available for their intended use.
Borrowing costs	Borrowing costs Borrowing costs that are directly attributable to the acquisition, construction or production of an asset that takes a substantial period of time to prepare for its intended use are capitalized as part of the cost of the asset. Capitalization of borrowing costs begins when there are borrowings, and activities commence to prepare an asset for its intended use. Capitalization of borrowing costs ends when substantially all activity necessary to prepare a qualifying asset for its intended use are complete. When proceeds of project-specific borrowings are invested on a temporary basis, borrowing costs are capitalized net of any investment income.
Exploration and evaluation expenditures	Exploration and evaluation expenditures Exploration and evaluation expenditures include the costs of acquiring licenses and costs associated with exploration and evaluation activity. Exploration and evaluation expenditures are capitalized. Mineral property acquisition costs are capitalized. Exploration and evaluation costs incurred before the Company has obtained the legal rights to explore an area are expensed. Once the technical feasibility and commercial viability of the extraction of mineral reserves or mineral resources from a particular mineral property has been determined, expenditures are reclassified to mineral properties within mineral properties, plant and equipment. The establishment of technical feasibility and commercial viability of a mineral property is assessed based on a combination of factors, including: · The extent to which mineral reserves or mineral resources as defined in National Instrument 43‑101, Standards of Disclosure for Mineral Projects (“NI 43-101”) have been identified through a feasibility study or similar document; · The results of optimization studies and further technical evaluation carried out to mitigate project risks identified in the feasibility study; · The status of environmental permits; and · The status of mining leases or permits. Exploration and evaluation assets are tested for impairment immediately prior to reclassification to mineral properties. Effective January 1, 2021, management will adopt a change to its accounting policy related to exploration and evaluation expenditures. Refer to note 5 of these consolidated financial statements for further details.
Mineral interests	Mineral interests Mineral interests consist of acquired royalty interests pursuant to purchase agreements on exploration and evaluation stage projects. Mineral interests are recorded at cost. Mineral interests are subsequently measured at cost less accumulated depletion and accumulated impairment losses, if any.
Mineral exploration tax credits	Mineral exploration tax credits Mineral exploration tax credits on eligible mineral exploration expenditures incurred are treated as a reduction of capitalized mineral properties, plant and equipment. The credits are recorded as a receivable when the amount is reliably measurable, and it is considered probable that the tax credit will be recovered.
Impairment of non-financial assets	Impairment of non-financial assets The carrying amounts of assets included in mineral properties, plant and equipment are reviewed for impairment whenever facts and circumstances suggest that the carrying amounts may not be recoverable. If there are indicators of impairment, the recoverable amount of the asset is estimated in order to determine the extent of any impairment. Where the asset does not generate cash flows that are independent from other assets, the recoverable amount of the cash generating unit ("CGU") to which the asset belongs is determined. The recoverable amount of an asset or CGU is determined as the higher of its fair value less costs of disposal (“FVLCD”) and its value in use. An impairment loss exists if the asset's or CGU's carrying amount exceeds the recoverable amount and is recorded as an expense immediately. Fair value is the price that would be received from selling an asset in an orderly transaction between market participants at the measurement date. Costs of disposal are incremental costs directly attributable to the disposal of an asset. Future cash flows are estimated using the following significant assumptions: mineral reserves and mineral resources, production profile, operating costs, capital costs, commodity prices, foreign exchange rates and discount rates. All inputs used are those that an independent market participant would consider appropriate. Value in use is determined as the present value of the future cash flows expected to be derived from continuing use of an asset or cash generating unit in its present form. These estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset or cash generating unit for which estimates of future cash flows have not been adjusted. Tangible assets that have been impaired in prior periods are tested for possible reversal of impairment whenever events or changes in circumstances indicate that the impairment has reversed. If the impairment has reversed, the carrying amount of the asset is increased to its recoverable amount, but not beyond the carrying amount that would have been determined had no impairment loss been recognized for the asset in the prior periods. A reversal of an impairment loss is recognized into earnings (loss) immediately.
Leases	Leases At the inception of a contract, the Company assesses whether a contract is, or contains, a lease based on whether the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset, the Company assesses whether: · The contract involves the use of an identified asset, either explicitly or implicitly, including consideration of supplier substitution rights; · The Company has the right to obtain substantially all the economic benefits from the use of the asset throughout the period of use; and · The Company has the right to direct the use of the asset. The right of use ("ROU") asset is initially measured based on the initial amount of the lease obligation plus any initial direct costs incurred less any lease incentives received. The assets are depreciated to the earlier of the end of the useful life of the ROU asset or the lease term using either the straight-line or units-of-production method depending on which method more accurately reflects the expected pattern of consumption of the future economic benefits. The lease term includes periods covered by an option to extend if the Company is reasonably certain to exercise that option. The ROU asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease obligation. The lease obligation is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company's incremental borrowing rate. Generally, the Company uses its incremental borrowing rate as the discount rate. The lease obligation is measured at amortized cost using the effective interest method and remeasured when there is a change in future lease payments. Future lease payments can arise from a change in an index or rate, if there is a change in the Company's estimate of the expected payable under a residual value guarantee, or if the Company changes its assessment of whether it will exercise a purchase, extension or termination option. When the lease obligation is remeasured, a corresponding adjustment is made to the carrying amount of the ROU asset, or is recorded to the statement of earnings (loss) if the carrying amount of the ROU asset has been reduced to zero.
Decommissioning and restoration provision	Decommissioning and restoration provision The Company has provisions for decommissioning and restoration costs which include the dismantling and demolition of infrastructure and the removal of residual materials and remediation of disturbed areas. Decommissioning and restoration costs are a normal consequence of mining and a majority of decommissioning and restoration expenditures are expected to be incurred at the end of the life of mine. Decommissioning and restoration costs are estimated and discounted to their net present value and capitalized to the carrying amount of the related asset along with the recording of a corresponding liability, as soon as the obligation to incur such costs arises. The discount rate used to calculate the net present value is a pre-tax rate of similar maturity that reflects current market assessment of time value of money and the risks specific to the liability. Each period the Company reviews cost estimates and other assumptions used in the valuation of the provision to reflect events, changes in circumstances and new information available. The liability is adjusted each reporting period for the unwinding of the discount, changes to the current market-based discount rate and for the amount or timing of the underlying cash flows needed to settle the provision.
Share capital	Share capital Common shares are classified as equity. Transaction costs directly attributable to the issue of common shares and share options are recognized as a deduction from equity, net of any tax effects.
Revenue recognition	Revenue recognition The Company produces doré and concentrates which contain both gold and silver. The doré is further processed to produce refined metals for sale. The concentrates are sold to traders in concentrate form. The Company’s performance obligations relate primarily to the delivery of mine production in refined or concentrate form to its customers. Revenue is recognized when control is transferred to the customer. Control transfers when a product is delivered to the customer, the customer has full discretion over the product and there is no unfulfilled obligation that could affect the customer’s acceptance of the product. Control over the refined gold or silver produced from doré is transferred to the customer and revenue recognized upon delivery to the customer’s bullion account. For shipment of doré, approximately 95% - 99% of the estimated contained gold is available to be delivered to the customer's bullion account within approximately 10 days of arrival at the refinery. The balance of the contained gold is delivered to the customer's bullion account following the final processing outturn. The contained silver is sold following the final processing outturn. Control over gold and silver bearing concentrates is transferred to the customer and revenue recognized when the concentrates are loaded or available for loading onto the vessel at the port of discharge. Revenue from concentrate sales are recognized net of treatment costs and refining charges. Revenue is recognized at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring the product to the customer. Sales of refined gold are recorded at the spot price on the date of delivery to the customer’s bullion account with payment received on the same day. Sales of silver are recorded at the spot price on the date of sale. Concentrate sales are recorded at the provisional price based on the estimated forward price to the date of final settlement. The final purchase price for these gold concentrate sales will be the average price for a period of time following the bill of lading date depending on the customer. Adjustments are made in subsequent periods to the customer receivables for these sales transactions based on movements in market prices prior to final pricing. As a result, concentrate sales receivables are fair valued and adjusted each period to reflect forward market prices to the estimated settlement date. These changes in fair value are included in revenue on the statement of earnings (loss). The Company receives payment for 90% – 92.5% of the value of each concentrate shipment 5 – 15 days after the loading of the material at the port of discharge. A final payment for 8.5% - 10% of the value of each sale is received upon completion of final assays and final pricing based on a defined pricing period. Revenue recognition under the offtake agreement (2019) Under the offtake agreement, the Company was required to deliver gold equivalent to 100% of production up to 7,067,000 ounces (note 10). Refined gold and silver were delivered directly to the offtakers and recorded at the spot price on the date of delivery. The final purchase price to be paid under the offtake agreement was, at the purchaser’s option, a market referenced gold price in USD per ounce during a defined pricing period after the date of each sale. The difference between the spot price on the date of sale and the price paid by the purchaser reflected the settlement of a portion of the offtake obligation previously recorded on the statement of financial position. The Company received payment for 90% of the value of each gold sale within 2 days of the date of sale. A final payment for 10% of the value of each gold sale, taking into account the purchaser’s pricing option, was received on the 7 th day after the date of sale. The Company repurchased 100% of the offtake agreement on September 30, 2019 eliminating the Company’s obligation to deliver gold to the holders of the offtake agreement.
Share-based payments	Share-based payments Share options Options granted to employees under the Company’s equity settled share-based option plan are measured at fair value at the date of grant. Fair value is determined using the Black-Scholes option pricing model, which relies on estimates of the risk-free interest rate, expected share price volatility, future dividend payments and the expected average life of the options. The fair value determined at the grant date is recognized as an expense over the vesting period in accordance with the vesting terms and conditions (graded vesting method), with a corresponding increase in contributed surplus in equity. Restricted share units (“RSU’s”) RSU’s are granted to employees of the Company and are expected to be settled in cash. The fair value of a RSU is estimated based on the quoted market price of the Company’s common shares. The initial fair value of the liability is calculated as of the grant date and is recognized as share-based compensation expense in the statement of earnings (loss) on a graded vesting basis over the vesting period. Subsequently, at each reporting date and on settlement, the liability is re-measured with any changes in fair value recorded to the statement of earnings (loss) Performance share units (“PSU’s”) PSU’s are granted under the Company’s RSU Plan and are expected to be settled in cash. The number of units to be issued on the vesting date will vary from 0% to 200% of the number of PSU’s granted, depending on the achievement of performance criteria set by the Board of Directors. Vesting, and therefore the liability, is based on the estimated probability of achieving the performance criteria. The fair value of a PSU is estimated based on the quoted market price of the Company's common shares price and the number of PSU's estimated to be issued is dependent upon the estimated probability of achieving the performance criteria. The initial fair value of the liability is calculated as of the grant date and is recognized as share-based compensation expense over the vesting period in accordance with the vesting terms and conditions. Subsequently, at each reporting date and on settlement, the liability is re-measured with any changes in fair value recorded to the statement of earnings (loss). Deferred share units (“DSU’s”) DSU’s are granted to independent directors of the Company and are settled in cash when the individual ceases to be a director of the Company, either voluntarily or involuntarily. DSU’s vest immediately on the grant date. The fair value of a DSU reflects the value of a Company common share based on the quoted market price. The initial fair value of the liability is calculated as of the grant date and is recognized as share-based compensation expense. Subsequently, at each reporting date and on settlement, the liability is re-measured with any changes in fair value recorded to the statement of earnings (loss).
Income and mining taxes	Income and mining taxes Income taxes include Canadian federal and provincial income taxes. Provincial mining taxes represent Canadian provincial taxes levied on mining operations. To the extent these taxes are determined based on a measure of taxable earnings, they are also accounted for as income taxes. Income tax is recognized in earnings (loss) except to the extent that it relates to items recognized directly in equity, in which case it is recognized in equity. Current tax expense is the expected tax payable on the taxable earnings for the year, using tax rates enacted or substantively enacted at year end, adjusted for amendments to tax payable with regards to previous years. Deferred tax is provided for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Temporary differences are not provided for the initial recognition of assets or liabilities that affect neither accounting nor taxable earnings. The amount of deferred tax provided is based on the expected manner of realization or settlement of the carrying amount of assets and liabilities, using tax rates at the end of the reporting year applicable to the year of expected realization. A deferred tax asset is recognized only to the extent that it is probable that future taxable earnings will be available against which the asset can be utilized.
Contingent liabilities	Contingent liabilities Contingent liabilities are possible obligations whose existence will only be confirmed by future events not wholly within the control of the Company. Contingent liabilities are disclosed unless the possibility of an outflow of economic resources is considered remote.
Earnings (loss) per share	Earnings (loss) per share The Company presents basic earnings (loss) per share data, calculated by dividing the earnings (loss) attributable to common shareholders of the Company by the weighted average number of common shares outstanding during the year. Diluted earnings (loss) per share is determined by adjusting the earnings (loss) attributable to common shareholders and the weighted average number of common shares outstanding for the effects of all dilutive potential common shares.
