Disclosure of interim financial reporting [text block] [Abstract]
Basis of preparation	2. Basis of preparation A. Statement of compliance 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 financial statements were authorized for issuance by the Board of Directors of the Company on March 23, 2021. B. Basis of consolidation (i) Subsidiaries Subsidiaries are entities over which the Company has control. Control over an entity exists when the Company is exposed or has rights to returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date on which control ceases. Business acquisitions are accounted for using the acquisition method whereby acquired assets and liabilities are recorded at fair value as of the date of acquisition with the excess of the purchase consideration over such fair value being recorded as goodwill and allocated to cash generating units. Non-controlling interest in an acquisition may be measured at either fair value or at the non-controlling interest’s proportionate share of the fair value of the acquiree’s net identifiable assets. If the fair value of the net assets acquired exceeds the purchase consideration, the difference is recognized immediately as a gain in the consolidated statement of operations and comprehensive loss. Where a business combination is achieved in stages, previously held non-controlling equity interests in the acquiree are re-measured at acquisition-date fair value and any resulting gain or loss is recognized in the consolidated statement of operations and comprehensive loss or other comprehensive income, as appropriate. Acquisition related costs are expensed during the period in which they are incurred, except for the cost of debt or equity instruments issued in relation to the acquisition which is included in the carrying amount of the related instrument. Certain fair values may be estimated at the acquisition date pending confirmation or completion of the valuation process. Where provisional values are used in accounting for a business combination, they may be adjusted retrospectively during the measurement period. However, the measurement period will not exceed one year from the acquisition date. (ii) Associates An associate is an entity over which the Company has significant influence but not control nor joint control. Significant influence is presumed to exist where the Company has between 20% and 50% of the voting rights but can also arise where the Company has less than 20% if influence is exerted over policy decisions that affect the entity. The Company’s share of the net assets and net income or loss of associates is accounted for in the consolidated financial statements using the equity method of accounting.

Disclosure of significant accounting policies [text block] [Abstract]
Significant accounting policies	3. Significant accounting policies The significant accounting policies used in the preparation of these consolidated financial statements are described below. A. Basis of measurement The consolidated financial statements have been prepared on the historical cost basis, except certain financial instruments described in note “L”, which are measured at fair value. B. Translation of foreign currencies These consolidated financial statements are presented in Canadian dollars, which is the Company’s, and each of its subsidiaries’, functional currency. Foreign currency transactions are translated into Canadian dollars using the exchange rates prevailing at the dates of the transactions or valuation where items are re-measured. Foreign exchange gains and losses resulting from the settlement of such transactions are recognized in the consolidated statement of operations and comprehensive loss. Monetary assets and liabilities of the Company denominated in a foreign currency are translated into Canadian dollars at the rate of exchange at the statement of financial position date. Non-monetary assets and liabilities are translated at historical rates. Revenues and expenses are translated at average exchange rates prevailing during the period. Exchange gains and losses are included in the determination of profit or loss for the year. C. Critical accounting judgments and estimation uncertainty In applying the Company’s accounting policies in conformity with IFRS, management is required to make judgments, estimates and assumptions about the carrying amounts of certain assets and liabilities. These estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Actual results may differ from these estimates. (i) Critical accounting judgments The following are the critical judgments that the Company has made in the process of applying the Company’s accounting policies and that have the most significant effect on the amounts recognized in the consolidated financial statements (refer to appropriate accounting policies for details). Mineral reserves and resources To calculate reserves and resources, the Company uses assumptions and evaluates technical, economic and geological conditions for each ore body. Measured grade of the ore and geotechnical considerations can have a significant effect on the carrying value of mineral properties and therefore the recoverability of costs. Future market prices for gold and copper and other commodities are also factored into valuation models. Changes to these factors can affect the recoverability of mineral properties and impairment. Impairment of assets When the Company has judged that an indication of impairment exists, such as a significant or prolonged decline in the fair value of an investment in marketable securities or an indication that the carrying amount of the mineral interest exceeds its estimated recoverable amount, the investment value or carrying value is written down to fair value or recoverable amount and the loss is recognized in the statement of operations and comprehensive loss. Also, the Company performs an impairment test if the period for which the Company has the right to explore within the project has expired during the period or will expire in the near future and is not expected to be renewed. Asset retirement obligations When the Company has judged that a constructive or legal obligation exists for reclamation and rehabilitation activities on mineral claims disturbed, an estimate of future costs is recognized as an expense on the statement of operations and comprehensive loss. (ii) Key sources of estimation uncertainty Mineral properties The recoverability of the carrying value of mineral properties and associated deferred exploration expenses is based on market conditions for minerals, underlying mineral resources associated with the properties and future costs that may be required for ultimate realization through mining operations or by sale. The Company is in an industry that is dependent on a number of factors including environmental, legal and political risks, the existence of economically recoverable reserves, the ability of the Company and its subsidiaries to obtain necessary financing to complete the development, and future profitable production or the proceeds of disposition thereof. Asset retirement obligations The provision for asset retirement obligations is the best estimate of the present value of the future costs of reclaiming the environment that has been subject to disturbance through exploration activities or historical mining activities. The Company uses assumptions and evaluates technical conditions for each project that have inherent uncertainties, including changes to laws and practices and changes in the status of the site from time-to-time. The timing and cost of the rehabilitation is also subject to uncertainty. For the Closed Sites, these changes, if any, and changes in discount rates are charged directly to the consolidated statement of operations and comprehensive loss. The periodic unwinding of the discount is recognized in earnings as accretion expense included in finance costs in the consolidated statement of operations and comprehensive loss. Share based payments The factors affecting stock-based compensation include estimates of when stock options and restricted share units might be exercised share price volatility and the assessment of the probability and timing of those instruments that have non-market performance vesting criteria. The timing for exercise of options is out of the Company’s control and will depend upon a variety of factors, including the market value of the Company’s shares and financial objectives of the share-based instrument holders. The Company uses historical data to determine volatility in accordance with appropriate fair value methodology. However, the future volatility is uncertain, and the model has its limitations. Deferred Income taxes The Company has operations in Canada and the United States and files corporate tax returns in each. Deferred tax liabilities are estimated for tax that may become payable in the future. Future payments could be materially different from our estimated deferred tax liabilities. We have deferred tax assets related to non-capital losses and other deductible temporary differences. Deferred tax assets are only recognized to the degree that it shelters tax liabilities or when it is probable that there will be sufficient taxable income in the future to recover them. Contingencies The Company funds certain of its exploration expenditures, from time-to-time, with the proceeds from the issuance of flow-through shares and renounces, to subscribers, the expenditures which it determines to be Canadian Exploration Expenses (“CEE”). The Canada Revenue Agency (“CRA”) has disputed the eligibility of certain types of expenditures within the years 2014 to 2016. The Company strongly disagrees with their position and intends to fully defend the Company’s tax filings. No provision has been recorded related to the contingent taxes if the Company does not consider it probable that there will ultimately be an amount payable. D. Mineral interests Mineral resource properties are carried at cost. The Company considers exploration and development costs and expenditures to have the characteristics of property and equipment and, as such, the Company capitalizes all exploration costs, which include acquisition costs, advance royalties, holding costs, field exploration and field supervisory costs and all costs associated with exploration and evaluation activities relating to specific properties as incurred, until those properties are determined to be economically viable for mineral production. General and administrative costs are only included in the measurement of exploration and evaluation costs where they are related directly to activities in a particular area of interest. The fair value of any recoveries from the disposition or optioning of a mineral property is credited to the carrying value of mineral properties. Once a project has been established as commercially viable and technically feasible, related development expenditures are capitalized. This includes costs incurred in preparing the site for mining operations. Capitalization ceases when the mine is capable of operating as intended by management. The actual recoverable value of capitalized expenditures for mineral properties and deferred exploration costs will be contingent upon the discovery of economically viable reserves and the Company’s financial ability at that time to fully exploit these properties or determine a suitable plan of disposition. When a decision is made to proceed with development in respect of a particular area of interest, the relevant exploration and evaluation asset is tested for impairment, reclassified to development properties, and then amortized over the life of the reserves associated with the area of interest once mining operations have commenced. E. Leasing arrangements Leases are recognized as a right-of-use (“ROU”) asset and a corresponding liability at the date at which the leased asset is available for use by the Company. Each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease period. The ROU asset is depreciated over the shorter of the asset's useful life and the lease term on a straight-line basis. Payments associated with short-term leases and leases of low-value assets are recognized on a straight-line basis as an expense in profit or loss. Short-term leases are leases with a lease term of 12 months or less. F. Impairment and reversal of impairment (i) Financial assets Financial assets measured at amortized cost are reviewed for impairment at each reporting date to determine whether there is any objective evidence of impairment. A financial asset is considered to be impaired if objective evidence, that can be estimated reliably, indicates that one or more events have had a negative effect on the estimated future cash flows of that asset. An impairment charge in respect of a financial asset measured at amortized cost is calculated as the difference between its carrying amount and the present value of the estimated future cash flows discounted at the original effective interest rate. A prior period impairment charge is reviewed for possible reversal of impairment whenever an event or change in circumstance indicates the impairment may have reversed. If it has been determined that the impairment has reversed, the carrying amount of the asset is increased to its recoverable amount to a maximum of the carrying amount that would have been determined had no impairment charge been recognized in prior periods. Impairment charge reversals are recognized in the Consolidated Statement of Operations and Comprehensive Loss. (ii) Non-financial assets The carrying value of the Company's mineral interests is assessed for impairment when indicators of such impairment exist. Indicators may include the loss of the right to explore in the area; the Company deciding not to continue exploring or incur substantial additional expenditures on the project; or it is determined that the carrying amount of the project is unlikely to be recovered by its development or sale. If any indication of impairment exists, an estimate of the asset's recoverable amount is calculated to determine the extent of the impairment loss, if any. The recoverable amount is determined as the higher of the fair value less costs of disposal for the asset and the asset's value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted. Impairment is determined on an asset by asset basis, whenever possible. If it is not possible to determine impairment on an individual asset basis, then impairment is considered on the basis of a cash generating unit (“CGU”). CGUs represent the lowest level for which there are separately identifiable cash inflows that are largely independent of the cash flows from other assets or other group of assets. If the carrying amount of the asset exceeds its recoverable amount, the asset is impaired, and an impairment loss is charged immediately to comprehensive loss within the statement of operations and comprehensive loss so as to reduce the carrying amount to its recoverable amount. An assessment is made at each reporting date as to whether there is any indication that previously recognized impairment losses may no longer exist or may have decreased. If such indication exists, the Company makes an estimate of the recoverable amount. A previously recognized impairment loss is reversed only if there has been a change in the estimates used to determine the asset's recoverable amount since the last impairment loss was recognized. If this is the case, the carrying amount of the asset is increased to its recoverable amount. The increased amount cannot exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset in prior years. Such reversal is recognized in the statement of operations and comprehensive loss. G. Reclamation liabilities Provisions for environmental restoration are recognized when: (i) the Company has a present legal or constructive obligation as a result of past exploration, development or production events; (ii) it is probable that an outflow of resources will be required to settle the obligation; (iii) and the amount can be reliably estimated. Provisions do not include obligations which are expected to arise from future disturbance. Provisions are measured at the present value of the expenditures expected to be required to settle the obligation incorporating risks specific to the obligation using a pre-tax rate that reflects current market assessments of the time value of money. When estimates of obligations are revised, the present value of the changes in obligations is recorded in the period by a change in the obligation amount and a corresponding adjustment to the mineral interest asset. The amortization or ‘unwinding’ of the discount applied in establishing the net present value of provisions due to the passage of time is charged to the statement of operations and comprehensive loss in each accounting period. The ultimate cost of environmental remediation is uncertain and cost estimates can vary in response to many factors including changes to the relevant legal requirements, the emergence of new restoration techniques or experience at other mine sites. The expected timing of expenditure can also change, for example in response to changes in ore reserves or production rates. As a result, there could be significant adjustments to the provisions for restoration and environmental cleanup, which would affect future financial results. Funds on deposit with third parties provided as security for future reclamation costs are included in reclamation deposits on the statement of financial position. H. Income taxes Income tax expense comprises current and deferred tax. Current and deferred tax are recognized in profit or loss except to the extent that it relates to a business combination or items recognized directly in equity. Current tax is the expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted at the reporting date, and any adjustment to tax payable in respect of previous years. Deferred tax is recognized using the asset and liability method, providing for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax is measured at the rates that are expected to be applied to temporary differences when they reverse, based on the laws that have been enacted or substantively enacted by the reporting date. Deferred tax is not recognized for the following temporary differences; the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss, and differences relating to investments in subsidiaries and jointly controlled entities to the extent that it is probable that they will not reverse in the foreseeable future where the timing of the reversal of the temporary differences can be controlled by the parent. In addition, deferred tax is not recognized for taxable temporary differences arising on the initial recognition of goodwill which is not deductible for tax purposes. A deferred tax asset is recognized only to the extent that it is probable that future taxable profits will be available against which the asset can be utilized. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefit will be realized. The Company has certain non-monetary assets and liabilities for which the tax reporting currency is different from its functional currency. Any translation gains or losses on the remeasurement of these items at current exchange rates versus historic exchange rates that give rise to a temporary difference is recorded as a deferred tax asset or liability. I. Stock-based compensation (options and restricted share units) The Company applies the fair value method for stock-based compensation and other stock-based payments. The fair value of options is valued using the Black Scholes option-pricing model and other models for the two-tiered options and restricted share units as may be appropriate. The grant date fair value of stock-based payment awards granted to employees is recognized as an employee expense, with a corresponding increase in equity, over the period that the employees unconditionally become entitled to the awards. The amount recognized as an expense is adjusted to reflect the number of awards for which the related service and non-market vesting conditions are expected to be met, such that the amount ultimately recognized as an expense is based on the number of awards that meet the related service and non-market performance conditions at the vesting date (Note 12). The Company reviews estimated forfeitures of options on an ongoing basis. J. Flow-through shares The Company finances a portion of its exploration activities through the issuance of flow-through common shares. The tax deductibility of qualifying expenditures is transferred to the investor purchasing the shares. Consideration for the transferred deductibility of the qualifying expenditures is often paid through a premium price over the market price of the Company’s shares. The Company reports this premium as a liability on the statement of financial position and the balance is reported as share capital. At each reporting period, and as qualifying expenditures have been incurred, the liability is reduced on a proportionate basis and income is recognized in the statement of operations and comprehensive loss. K. Net profit (loss) per common share Basic profit (loss) per common share is computed based on the weighted average number of common shares outstanding during the year. The Company uses the treasury stock method for calculating diluted earnings per share which assumes that stock options and RSUs with an exercise price lower than the average quoted market price were exercised at the later of the beginning of the year, or time of issue. Stock options with an exercise price greater than the average quoted market price of the common shares and RSUs are not included in the calculation of diluted profit (loss) per share as the effect is anti-dilutive. L. Financial instruments The Company recognizes financial assets and financial liabilities on the date the Company becomes a party to the contractual provisions of the instruments. A financial asset is derecognized either when the Company has transferred substantially all the risks and rewards of ownership of the financial asset or when cash flows expire. A financial liability is derecognized when the obligation specified in the contract is discharged, canceled or expired. Certain financial instruments are recorded at fair value in the consolidated statement of financial position. Refer to note 13 on fair value measurements. Non-derivative financial instruments Non-derivative financial instruments are recognized initially at fair value plus attributable transaction costs, where applicable for financial instruments not classified as fair value through profit or loss. Subsequent to initial recognition, non-derivative financial instruments are classified and measured as described below. Financial assets at fair value through profit or loss Cash and cash equivalents and short-term deposits are classified as financial assets at fair value through profit or loss and are measured at fair value. Cash equivalents are short-term deposits with maturities of up to 90 days at the date of purchase. Short-term deposits consist of investments with maturities from 91 days to one year at the date of purchase. Convertible notes receivable are recorded at fair value through profit or loss. Financial assets at amortized cost Trade and other receivables and are classified as and measured at amortized cost using the effective interest rate method, less impairment losses, if any. Financial assets at fair value through other comprehensive income The Company’s investments in equity marketable securities are designated as financial assets at fair value through other comprehensive income and are recorded at fair value on the trade date with directly attributable transaction costs included in the recorded amount. Subsequent changes in fair value are recognized in other comprehensive income. Non-derivative financial liabilities Accounts payable and accrued liabilities are accounted for at amortized cost, using the effective interest rate method. M. Accounting pronouncements New and amended standards and interpretations issued and effective: Adoption of Definition of a Business (Amendments to IFRS 3) The Company has adopted the amendments to IFRS 3 for the first time in the current year. The amendments clarify that while businesses usually have outputs, outputs are not required for an integrated set of activities and assets to qualify as a business. To be considered a business an acquired set of activities and assets must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. The amendments remove the assessment of whether market participants are capable of replacing any missing inputs or processes and continuing to produce outputs. The amendments also introduce additional guidance that helps to determine whether a substantive process has been acquired. The amendments introduce an optional concentration test that permits a simplified assessment of whether an acquired set of activities and assets is not a business. Under the optional concentration test, the acquired set of activities and assets is not a business if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar assets. The amendments are applied prospectively to all business combinations and asset acquisitions for which the acquisition date is on or after January 1, 2020. The amendments were applied to the Company's acquisition of 3 Aces gold project and Snowfield property, where the Company concluded that the acquired set of activities and assets was not a business. Refer to Note 8 for further details. New accounting standards issued but not yet effective: Amendments to IAS 16 - Property, Plant and Equipment: Proceeds before Intended Use The IASB issued an amendment to IAS 16, Property, Plant and Equipment to prohibit the deducting from property, plant and equipment amounts received from selling items produced while preparing an asset for its intended use. Instead, sales proceeds and its related costs must be recognized in profit or loss. The amendment will require companies to distinguish between costs associated with producing and selling items before the item of property, plant and equipment is available for use and costs associated with making the item of property, plant and equipment available for its intended use. The amendment is effective for annual periods beginning on or after January 1, 2022, with earlier application permitted. The amendments apply retrospectively, but only to assets brought to the location and condition necessary for them to be capable of operating in the manner intended on or after the beginning of the earliest period presented in the financial statements in which the Company first applies the amendments. The Company does not expect the adoption of this pronouncement to have a material impact on its consolidated financial statements. Other pronouncements have been issued by the IASB that are not mandatory for the current period and have not been early adopted. These pronouncements are not expected to have a material impact on the Company's consolidated financial statements upon adoption.

The vendor maintains a 1% net smelter royalty interest on the project, subject to maximum aggregate royalty payments of $4.5 million. The Company is obligated to purchase the net smelter royalty interest for the price of $4.5 million in the event that a positive feasibility study demonstrates a 10% or higher internal rate of return after tax and financing costs. In July 2009, the Company agreed to acquire various mineral claims immediately adjacent to the KSM property for further exploration and possible mine infrastructure use. The acquired claims were subject to a 4.5% net smelter royalty. In January 2019, the Company issued 100,000 common shares at $17.30 per common share, for total fair value of $1.7 million, to the holder of the net smelter return royalty on the claims and fully extinguished the royalties on those claims. The total fair value of the common shares was recorded to the mineral interest at KSM project. In 2011 and 2012, the Company completed agreements granting a third party an option to acquire a 2% net smelter royalty on all gold and silver production sales from KSM for a payment equal to the lesser of $160 million or US$200 million. The option is exercisable for a period of 60 days following the announcement of receipt of all material approvals and permits, full project financing and certain other conditions for the KSM Project. During 2019, as part of a cooperative and benefit agreement between the Company and the Tahltan Nation, the Company issued 50,000 common shares with a fair value of $18.63 per common share, for a total fair value of $0.9 million. In December 2020, the company purchased the Snowfield property from Pretium Resources Inc. The Snowfield property, located in the same valley that hosts KSM's Mitchell deposit, was purchased for US$100 million ($127.5 million) in cash, a 1.5% net smelter royalty on Snowfield property production, and a conditional payment of US$20 million, payable following the earlier of (i) commencement of commercial production from Snowfield property, and (ii) announcement by the Company of a bankable feasibility study which includes production of reserves from the Snowfield property. US$15 million of the conditional payment can be credited against future royalty payments. b) Courageous Lake In 2002, the Company purchased a 100% interest in the Courageous Lake gold project from Newmont Canada Limited and Total Resources (Canada) Limited for US$2.5 million. The Courageous Lake gold project consists of mining leases located in Northwest Territories of Canada. c) Iskut On June 21, 2016, the Company purchased 100% of the common shares of SnipGold Corp. which owns the Iskut Project, located in northwestern British Columbia. d) Snowstorm In 2017, the Company purchased 100% of the common shares of Snowstorm Exploration LLC which owns the Snowstorm Project, located in northern Nevada. On the acquisition date, the Company issued 700,000 common shares, with a fair value of $14.39 per share and 500,000 common share purchase warrants with a fair value of $6.55 per common share purchase warrant for a combined fair value of $13.3 million. The common share purchase warrants are exercisable for four years from the date of acquisition, at $15.65 per share. In addition, the Company has agreed to make a conditional cash payment of US$2.5 million if exploration activities at the Snowstorm Project result in defining a minimum of five million ounces of gold resources compliant with National Instrument 43-101 and a further cash payment of US$5.0 million on the delineation of an additional five million ounces of gold resources. In 2019, the Company purchased the Goldstorm Project in northern Nevada from Mountain View Gold Corp. in exchange for 25,000 common shares of the Company at a fair value of $21.11 per common share for a total fair value of $0.5 million. e) 3 Aces In 2020, the Company acquired a 100% interest in the 3 Aces gold project in the Yukon, Canada from Golden Predator Mining Corp through the issuance of 300,000 common shares valued at $6.6 million. Should the project attain certain milestones, including the confirmation of a National Instrument 43-101 compliant mineral resource of 2.5 million ounces of gold and upon confirmation of an aggregate mineral resource of 5 million ounces of gold, the Company will potentially pay an additional $2.25 million. f) Grassy Mountain In 2013, the Company sold 100% of interest in the Grassy Mountain Project with a net book value of $771,000 retained within mineral properties, related to the option to either receive, at the discretion of the Company, a 10% net profits interest royalty or a $10 million cash payment. Settlement is due four months after the later of: the day that the Company receives a feasibility study on the project; and the day that the Company is notified that permitting and bonding for the mine is in place. The current owner of the Grassy Mountain Project is Paramount who completed a feasibility study in 2020 but they have not notified the Company that permitting and bonding for the mine is in place.

The Company recorded a $3.6 million provision within non-trade payables and accrued expenses on the consolidated statements of financial position as at December 31, 2016. In 2017 the Company filed an objection to the reassessment with the appeals division of the tax authorities and paid one-half of the accrued balance while the objection is reviewed. In early 2019, the Company received a decision from the appeals division that the Company’s objection was denied, and the Company filed a notice of appeal with the British Columbia Supreme Court. The Attorney General of Canada replied to the facts and arguments in the Company’s Notice of Appeal and stated its position that the Company’s expenditures did not qualify for the BCMETC program. As at December 31, 2020, the Company is in the discovery process with the Department of Justice and will continue to move the appeal process forward as expeditiously as possible. The Company intends to continue to fully defend its position. As at December 31, 2020, the Canada Revenue Agency (CRA) has withheld $2.0 million of HST credits due to the Company that would fully cover the residual balance, including interest, should the Company be unsuccessful in its challenge.

As at December 31, 2020, the undiscounted future cash outflows are estimated at $6.2 million (December 31, 2019 – $7.0 million) primarily over the next two years. The discount rate used to calculate the present value of the reclamation obligations was 0.2% at December 31, 2020 (1.7% - December 31, 2019). Offsetting the increase in the present value of the liability, for the decreasing discount rate, is a comparable decrease in reported and anticipated inflation rates. For the year ended December 31, 2020, reclamation disbursements amounted to $0.8 million (2019 - $1.3 million). In 2020, the Company placed $5.2 million on deposit with a financial institution pledged as security for the Fish Habitat Offsetting Plan obligation at KSM. As at December 31, 2020, the Company has placed a total of $6.8 million (December 31, 2019 - $1.3 million) on deposit with financial institutions or with government regulators that are pledged as security against reclamation liabilities.

Shareholders’ equity	12. Shareholders’ equity The Company is authorized to issue an unlimited number of preferred shares and common shares with no par value. No preferred shares have been issued or were outstanding at December 31, 2020 or December 31, 2019. The Company manages its capital structure and makes adjustments to it, based on the funds available to the Company, in order to support the acquisition, exploration and development of mineral properties. The Board of Directors does not establish quantitative return on capital criteria for management, but rather relies on the expertise of the Company's management to sustain future development of the business. The properties in which the Company currently has an interest are in the exploration stage, as such the Company is dependent on external financing to fund its activities. In order to carry out the planned exploration and pay for administrative costs, the Company will spend its existing working capital and raise additional amounts as needed. Management reviews its capital management approach on an ongoing basis and believes that this approach, given the relative size of the Company, is reasonable. There were no changes in the Company's approach to capital management during 2020. The Company considers its capital to be share capital, stock-based compensation, warrants, contributed surplus and deficit. The Company is not subject to externally imposed capital requirements. a) Equity financings During the fourth quarter of 2019, the Company entered into an agreement with two securities dealers, for an At-The-Market offering program, entitling the Company, at its discretion, and from time to time, to sell up to US$40 million in value of common shares of the Company.

The effective date of the renouncement was December 31, 2018. At the time of issuance of the flow-through shares, $0.8 million premium was recognized as a liability on the consolidated statements of financial position with the balance recorded as share capital. During 2019, $5.1 million of qualifying exploration expenditures were incurred and the entire $0.8 million premium was recognized through other income on the consolidated statement of operations and comprehensive loss. b) Warrants As part of the acquisition agreement of Snowstorm Exploration LLC in June 2017, the Company issued 500,000 common share purchase warrants exercisable for four years at $15.65 per share, which are still outstanding as at December 31, 2020. c) Stock options and Restricted share units The Company provides compensation to directors and employees in the form of stock options and Restricted Share Units (“RSU”s).

At the end of the second quarter of 2019, shareholders approved the 408,000 options granted to the board members, and the fair value was re-estimated, at the time, resulting in an additional $0.4 million fair value to be recognized over the estimated service period. During the second quarter of 2019, the shareholders also approved the grant of 50,000 five-year options to a new board member, with an exercise price of $17.72 and fair value of $0.4 million. The options granted to board members and senior management vested in December 2020 upon the acquisition of the Snowfield property and $1.6 million of the fair value of these options, not previously expensed, was charged to the statement of operations and comprehensive loss on an accelerated basis to match the change in the estimate of the service period. In October 2018, 50,000 five-year options with an exercise price of $16.94, to purchase common shares of the Company, with a grant-date fair value of $0.4 million, were granted to a new Board member. These options also vested in December 2020 upon the acquisition of the Snowfield property and $0.1 million of the fair value of these options, not previously expensed, was charged to the statement of operations and comprehensive loss on an accelerated basis, to match the change in the estimated service period. During 2020, the Company did not grant any new options. The fair value of the options granted in 2019 was estimated on the dates of grant using a Black Scholes option-pricing model with the following assumptions: 2019 Dividend yield Nil Expected volatility 54% Risk-free rate of return 1.40% Expected life of options 5 year In December 2020, the Board granted 135,450 RSUs. Of these, 28,000 RSUs were granted to the board members, 80,300 RSUs were granted to members of senior management, and the remaining 27,150 RSUs were granted to other employees of the Company. The fair value of the grants, of $3.4 million, was estimated as at the grant date will be amortized over the expected service period of the grants. The expected service period of approximately four months from the date of the grant was dependent on certain corporate objectives being met. As at December 31, 2020, $0.5 million of the fair value of the grants was amortized. In December 2019, the Board granted 139,600 RSUs. Of these, 32,500 RSUs were granted to the board members, 74,200 RSUs were granted to members of senior management, and the remaining 32,900 RSUs were granted to other employees of the Company. The fair value of the grants, of $2.4 million, was estimated as at the grant date to be amortized over the expected service period of the grants. The expected service period of approximately six months from the date of the grant was dependent on certain corporate objectives being met. During the second quarter 2020, all 139,600 RSUs were vested. Of the $2.4 million total fair value of the RSUs, $0.3 million was amortized in December 2019, and the remaining $2.1 million was amortized during first half of 2020. Subsequent to December 31, 2020, 354,668 options were exercised for proceeds of $3.9 million. d) Basic and diluted net loss per common share For the years ended December 31, 2020 and 2019, basic and diluted net loss per common share are computed by dividing the net loss for the period by the weighted average number of common shares outstanding for the year. The potential effect of stock options, RSUs and warrants has been excluded from the calculation of diluted loss per common share as the effect would be anti-dilutive. At December 31, 2020, there was a total of 2,611,691 stock options and 135,450 RSUs outstanding (December 31, 2019 – 3,003,150 and 139,600 respectively).

Fair Value of Financial Assets and Liabilities	13. Fair value of financial assets and liabilities Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy establishes three levels to classify the inputs to valuation techniques used to measure fair value. Level 1: Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Inputs are quoted prices in markets that are not active, quoted prices for similar assets or liabilities in active markets, inputs other than quoted prices that are observable for the asset or liability (for example, interest rate and yield curves observable at commonly quoted intervals, forward pricing curves used to value currency and commodity contracts, volatility measurements used to value option contracts and observable credit default swap spreads to adjust for credit risk where appropriate), or inputs that are derived principally from or corroborated by observable market data or other means. Level 3: Inputs are unobservable (supported by little or no market activity). The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. The Company’s financial assets and liabilities as at December 31, 2020 and December 31, 2019 are cash and cash equivalents, short-term deposits, accounts receivable, marketable securities, convertible notes receivable and accounts payable. Other than investments and convertible notes receivable, the carrying values approximate their fair values due to the immediate or short-term maturity of these financial instruments and are classified as a Level 1 measurement. The Company’s equity investments are measured at fair value based on quoted market prices and are classified as a level 1 measurement. The convertible notes receivable are measured at fair value and are classified as a level 3 measurement. The Company's financial risk exposures and the impact on the Company's financial instruments are summarized below: Credit Risk The Company's credit risk is primarily attributable to short-term deposits, convertible notes receivable, and receivables included in amounts receivable and prepaid expenses. The Company has no significant concentration of credit risk arising from operations. The short-term deposits consist of Canadian Schedule I bank guaranteed notes, with terms up to one year but are cashable in whole or in part with interest at any time to maturity, for which management believes the risk of loss to be remote. Management believes that the risk of loss with respect to financial instruments included in amounts receivable and prepaid expenses to be remote. Liquidity Risk The Company's approach to managing liquidity risk is to ensure that it will have sufficient liquidity to meet liabilities when due. As at December 31, 2020, the Company had a cash and cash equivalents of $17.5 million and short-term deposits of $19.9 million (2019 - $8.8 million and $4.1 million, respectively) for settlement of current financial liabilities of $5.4 million (2019 - $4.7 million). The short-term deposits consist of Canadian Schedule I bank guaranteed deposits and are cashable in whole or in part with interest at any time to maturity. The Company's financial liabilities primarily have contractual maturities of 30 days and are subject to normal trade terms. The Company’s ability to fund its operations and capital expenditures and other obligations as they become due is dependent upon market conditions. As the Company does not generate cash inflows from operations, the Company is dependent upon external sources of financing to fund its exploration projects and on-going activities. If required, the Company will seek additional sources of cash to cover its proposed exploration and development programs at its key projects, in the form of equity financings and from the sale of non-core assets. Refer to note 12 for details on equity financings. Market Risk (a) Interest Rate Risk The Company has no interest-bearing debt. The Company's current policy is to invest excess cash in Canadian bank guaranteed notes (short-term deposits). The short-term deposits can be cashed in at any time and can be reinvested if interest rates rise. (b) Foreign Currency Risk The Company's functional currency is the Canadian dollar and major purchases are transacted in Canadian and US dollars. The Company funds certain operations, exploration and administrative expenses in the United States on a cash call basis using US dollar cash on hand or converted from its Canadian dollar cash. Management believes the foreign exchange risk derived from currency conversions is not significant to its operations and therefore does not hedge its foreign exchange risk. As at December 31, 2020, $10.1 million of cash and cash equivalents and $0.5 million of accounts payable and accrued liabilities are denominated in US dollars. (c) Investment Risk The Company has investments in other publicly listed exploration companies which are included in investments. These shares were received as option payments on certain exploration properties the Company owns or has sold. In addition, the Company holds $3.6 million in a gold exchange traded receipt that is recorded on the consolidated statements of financial position in investments. The risk on these investments is significant due to the nature of the investment but the amounts are not significant to the Company.

The Company has funded certain of its exploration expenditures, from time-to-time, with the proceeds from the issuance of flow-through shares and renounced, to subscribers, the expenditures which it determined to be CEE. The notice disputes the eligibility of certain types of expenditures previously audited and approved as CEE by the CRA. The Company strongly disagrees with the notice and responded to the CRA auditors with additional information for their consideration. In 2020, the CRA auditors responded to the Company’s submission and, although accepting additional expenditures as CEE, reiterated that their position remains largely unchanged and subsequently issued reassessments to the Company reflecting the additional CEE expenditures accepted and $2.3 million of Part Xll.6 tax owing. The Company has been made aware that the CRA has reassessed certain investors who subscribed for flow-through shares in 2013 and will reassess other investors with reduced CEE deductions. The Company’s and investors’ reassessments will be appealed to the courts. The Company has indemnified the investors that subscribed for the flow-through shares. The potential tax indemnification to the investors is estimated to be $11.0 million, plus $2.2 million potential interest. No provision has been recorded related to the tax, potential interest, nor the potential indemnity as the Company and its advisors do not consider it probable that there will ultimately be an amount payable. Subsequent to the year end, $2.4 million was deposited with the Receiver General, on behalf of certain investors in return for their agreement to object to their respective assessments and agreement to repay the Company with any and all recoveries upon the successful resolution of the Company’s successful appeal.

Accounting Policies [Abstract]
Basis of measurement	A. Basis of measurement The consolidated financial statements have been prepared on the historical cost basis, except certain financial instruments described in note “L”, which are measured at fair value.
Translation of foreign currencies	B. Translation of foreign currencies These consolidated financial statements are presented in Canadian dollars, which is the Company’s, and each of its subsidiaries’, functional currency. Foreign currency transactions are translated into Canadian dollars using the exchange rates prevailing at the dates of the transactions or valuation where items are re-measured. Foreign exchange gains and losses resulting from the settlement of such transactions are recognized in the consolidated statement of operations and comprehensive loss. Monetary assets and liabilities of the Company denominated in a foreign currency are translated into Canadian dollars at the rate of exchange at the statement of financial position date. Non-monetary assets and liabilities are translated at historical rates. Revenues and expenses are translated at average exchange rates prevailing during the period. Exchange gains and losses are included in the determination of profit or loss for the year.
Critical accounting judgments and estimation uncertainty	C. Critical accounting judgments and estimation uncertainty In applying the Company’s accounting policies in conformity with IFRS, management is required to make judgments, estimates and assumptions about the carrying amounts of certain assets and liabilities. These estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Actual results may differ from these estimates. (i) Critical accounting judgments The following are the critical judgments that the Company has made in the process of applying the Company’s accounting policies and that have the most significant effect on the amounts recognized in the consolidated financial statements (refer to appropriate accounting policies for details). Mineral reserves and resources To calculate reserves and resources, the Company uses assumptions and evaluates technical, economic and geological conditions for each ore body. Measured grade of the ore and geotechnical considerations can have a significant effect on the carrying value of mineral properties and therefore the recoverability of costs. Future market prices for gold and copper and other commodities are also factored into valuation models. Changes to these factors can affect the recoverability of mineral properties and impairment. Impairment of assets When the Company has judged that an indication of impairment exists, such as a significant or prolonged decline in the fair value of an investment in marketable securities or an indication that the carrying amount of the mineral interest exceeds its estimated recoverable amount, the investment value or carrying value is written down to fair value or recoverable amount and the loss is recognized in the statement of operations and comprehensive loss. Also, the Company performs an impairment test if the period for which the Company has the right to explore within the project has expired during the period or will expire in the near future and is not expected to be renewed. Asset retirement obligations When the Company has judged that a constructive or legal obligation exists for reclamation and rehabilitation activities on mineral claims disturbed, an estimate of future costs is recognized as an expense on the statement of operations and comprehensive loss. (ii) Key sources of estimation uncertainty Mineral properties The recoverability of the carrying value of mineral properties and associated deferred exploration expenses is based on market conditions for minerals, underlying mineral resources associated with the properties and future costs that may be required for ultimate realization through mining operations or by sale. The Company is in an industry that is dependent on a number of factors including environmental, legal and political risks, the existence of economically recoverable reserves, the ability of the Company and its subsidiaries to obtain necessary financing to complete the development, and future profitable production or the proceeds of disposition thereof. Asset retirement obligations The provision for asset retirement obligations is the best estimate of the present value of the future costs of reclaiming the environment that has been subject to disturbance through exploration activities or historical mining activities. The Company uses assumptions and evaluates technical conditions for each project that have inherent uncertainties, including changes to laws and practices and changes in the status of the site from time-to-time. The timing and cost of the rehabilitation is also subject to uncertainty. For the Closed Sites, these changes, if any, and changes in discount rates are charged directly to the consolidated statement of operations and comprehensive loss. The periodic unwinding of the discount is recognized in earnings as accretion expense included in finance costs in the consolidated statement of operations and comprehensive loss. Share based payments The factors affecting stock-based compensation include estimates of when stock options and restricted share units might be exercised share price volatility and the assessment of the probability and timing of those instruments that have non-market performance vesting criteria. The timing for exercise of options is out of the Company’s control and will depend upon a variety of factors, including the market value of the Company’s shares and financial objectives of the share-based instrument holders. The Company uses historical data to determine volatility in accordance with appropriate fair value methodology. However, the future volatility is uncertain, and the model has its limitations. Deferred Income taxes The Company has operations in Canada and the United States and files corporate tax returns in each. Deferred tax liabilities are estimated for tax that may become payable in the future. Future payments could be materially different from our estimated deferred tax liabilities. We have deferred tax assets related to non-capital losses and other deductible temporary differences. Deferred tax assets are only recognized to the degree that it shelters tax liabilities or when it is probable that there will be sufficient taxable income in the future to recover them. Contingencies The Company funds certain of its exploration expenditures, from time-to-time, with the proceeds from the issuance of flow-through shares and renounces, to subscribers, the expenditures which it determines to be Canadian Exploration Expenses (“CEE”). The Canada Revenue Agency (“CRA”) has disputed the eligibility of certain types of expenditures within the years 2014 to 2016. The Company strongly disagrees with their position and intends to fully defend the Company’s tax filings. No provision has been recorded related to the contingent taxes if the Company does not consider it probable that there will ultimately be an amount payable.
Mineral interests	D. Mineral interests Mineral resource properties are carried at cost. The Company considers exploration and development costs and expenditures to have the characteristics of property and equipment and, as such, the Company capitalizes all exploration costs, which include acquisition costs, advance royalties, holding costs, field exploration and field supervisory costs and all costs associated with exploration and evaluation activities relating to specific properties as incurred, until those properties are determined to be economically viable for mineral production. General and administrative costs are only included in the measurement of exploration and evaluation costs where they are related directly to activities in a particular area of interest. The fair value of any recoveries from the disposition or optioning of a mineral property is credited to the carrying value of mineral properties. Once a project has been established as commercially viable and technically feasible, related development expenditures are capitalized. This includes costs incurred in preparing the site for mining operations. Capitalization ceases when the mine is capable of operating as intended by management. The actual recoverable value of capitalized expenditures for mineral properties and deferred exploration costs will be contingent upon the discovery of economically viable reserves and the Company’s financial ability at that time to fully exploit these properties or determine a suitable plan of disposition. When a decision is made to proceed with development in respect of a particular area of interest, the relevant exploration and evaluation asset is tested for impairment, reclassified to development properties, and then amortized over the life of the reserves associated with the area of interest once mining operations have commenced
Leasing arrangements	E. Leasing arrangements Leases are recognized as a right-of-use (“ROU”) asset and a corresponding liability at the date at which the leased asset is available for use by the Company. Each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease period. The ROU asset is depreciated over the shorter of the asset's useful life and the lease term on a straight-line basis. Payments associated with short-term leases and leases of low-value assets are recognized on a straight-line basis as an expense in profit or loss. Short-term leases are leases with a lease term of 12 months or less.
Impairment and reversal of impairment	F. Impairment and reversal of impairment (i) Financial assets Financial assets measured at amortized cost are reviewed for impairment at each reporting date to determine whether there is any objective evidence of impairment. A financial asset is considered to be impaired if objective evidence, that can be estimated reliably, indicates that one or more events have had a negative effect on the estimated future cash flows of that asset. An impairment charge in respect of a financial asset measured at amortized cost is calculated as the difference between its carrying amount and the present value of the estimated future cash flows discounted at the original effective interest rate. A prior period impairment charge is reviewed for possible reversal of impairment whenever an event or change in circumstance indicates the impairment may have reversed. If it has been determined that the impairment has reversed, the carrying amount of the asset is increased to its recoverable amount to a maximum of the carrying amount that would have been determined had no impairment charge been recognized in prior periods. Impairment charge reversals are recognized in the Consolidated Statement of Operations and Comprehensive Loss. (ii) Non-financial assets The carrying value of the Company's mineral interests is assessed for impairment when indicators of such impairment exist. Indicators may include the loss of the right to explore in the area; the Company deciding not to continue exploring or incur substantial additional expenditures on the project; or it is determined that the carrying amount of the project is unlikely to be recovered by its development or sale. If any indication of impairment exists, an estimate of the asset's recoverable amount is calculated to determine the extent of the impairment loss, if any. The recoverable amount is determined as the higher of the fair value less costs of disposal for the asset and the asset's value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted. Impairment is determined on an asset by asset basis, whenever possible. If it is not possible to determine impairment on an individual asset basis, then impairment is considered on the basis of a cash generating unit (“CGU”). CGUs represent the lowest level for which there are separately identifiable cash inflows that are largely independent of the cash flows from other assets or other group of assets. If the carrying amount of the asset exceeds its recoverable amount, the asset is impaired, and an impairment loss is charged immediately to comprehensive loss within the statement of operations and comprehensive loss so as to reduce the carrying amount to its recoverable amount. An assessment is made at each reporting date as to whether there is any indication that previously recognized impairment losses may no longer exist or may have decreased. If such indication exists, the Company makes an estimate of the recoverable amount. A previously recognized impairment loss is reversed only if there has been a change in the estimates used to determine the asset's recoverable amount since the last impairment loss was recognized. If this is the case, the carrying amount of the asset is increased to its recoverable amount. The increased amount cannot exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset in prior years. Such reversal is recognized in the statement of operations and comprehensive loss.
Reclamation liabilities	G. Reclamation liabilities Provisions for environmental restoration are recognized when: (i) the Company has a present legal or constructive obligation as a result of past exploration, development or production events; (ii) it is probable that an outflow of resources will be required to settle the obligation; (iii) and the amount can be reliably estimated. Provisions do not include obligations which are expected to arise from future disturbance. Provisions are measured at the present value of the expenditures expected to be required to settle the obligation incorporating risks specific to the obligation using a pre-tax rate that reflects current market assessments of the time value of money. When estimates of obligations are revised, the present value of the changes in obligations is recorded in the period by a change in the obligation amount and a corresponding adjustment to the mineral interest asset. The amortization or ‘unwinding’ of the discount applied in establishing the net present value of provisions due to the passage of time is charged to the statement of operations and comprehensive loss in each accounting period. The ultimate cost of environmental remediation is uncertain and cost estimates can vary in response to many factors including changes to the relevant legal requirements, the emergence of new restoration techniques or experience at other mine sites. The expected timing of expenditure can also change, for example in response to changes in ore reserves or production rates. As a result, there could be significant adjustments to the provisions for restoration and environmental cleanup, which would affect future financial results. Funds on deposit with third parties provided as security for future reclamation costs are included in reclamation deposits on the statement of financial position.
Income taxes	H. Income taxes Income tax expense comprises current and deferred tax. Current and deferred tax are recognized in profit or loss except to the extent that it relates to a business combination or items recognized directly in equity. Current tax is the expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted at the reporting date, and any adjustment to tax payable in respect of previous years. Deferred tax is recognized using the asset and liability method, providing for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax is measured at the rates that are expected to be applied to temporary differences when they reverse, based on the laws that have been enacted or substantively enacted by the reporting date. Deferred tax is not recognized for the following temporary differences; the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss, and differences relating to investments in subsidiaries and jointly controlled entities to the extent that it is probable that they will not reverse in the foreseeable future where the timing of the reversal of the temporary differences can be controlled by the parent. In addition, deferred tax is not recognized for taxable temporary differences arising on the initial recognition of goodwill which is not deductible for tax purposes. A deferred tax asset is recognized only to the extent that it is probable that future taxable profits will be available against which the asset can be utilized. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefit will be realized. The Company has certain non-monetary assets and liabilities for which the tax reporting currency is different from its functional currency. Any translation gains or losses on the remeasurement of these items at current exchange rates versus historic exchange rates that give rise to a temporary difference is recorded as a deferred tax asset or liability.
Stock-based compensation (options and restricted share units)	I. Stock-based compensation (options and restricted share units) The Company applies the fair value method for stock-based compensation and other stock-based payments. The fair value of options is valued using the Black Scholes option-pricing model and other models for the two-tiered options and restricted share units as may be appropriate. The grant date fair value of stock-based payment awards granted to employees is recognized as an employee expense, with a corresponding increase in equity, over the period that the employees unconditionally become entitled to the awards. The amount recognized as an expense is adjusted to reflect the number of awards for which the related service and non-market vesting conditions are expected to be met, such that the amount ultimately recognized as an expense is based on the number of awards that meet the related service and non-market performance conditions at the vesting date (Note 12). The Company reviews estimated forfeitures of options on an ongoing basis.
Flow-through shares	J. Flow-through shares The Company finances a portion of its exploration activities through the issuance of flow-through common shares. The tax deductibility of qualifying expenditures is transferred to the investor purchasing the shares. Consideration for the transferred deductibility of the qualifying expenditures is often paid through a premium price over the market price of the Company’s shares. The Company reports this premium as a liability on the statement of financial position and the balance is reported as share capital. At each reporting period, and as qualifying expenditures have been incurred, the liability is reduced on a proportionate basis and income is recognized in the statement of operations and comprehensive loss.
Net profit (loss) per common share	K. Net profit (loss) per common share Basic profit (loss) per common share is computed based on the weighted average number of common shares outstanding during the year. The Company uses the treasury stock method for calculating diluted earnings per share which assumes that stock options and RSUs with an exercise price lower than the average quoted market price were exercised at the later of the beginning of the year, or time of issue. Stock options with an exercise price greater than the average quoted market price of the common shares and RSUs are not included in the calculation of diluted profit (loss) per share as the effect is anti-dilutive.
Financial instruments	L. Financial instruments The Company recognizes financial assets and financial liabilities on the date the Company becomes a party to the contractual provisions of the instruments. A financial asset is derecognized either when the Company has transferred substantially all the risks and rewards of ownership of the financial asset or when cash flows expire. A financial liability is derecognized when the obligation specified in the contract is discharged, canceled or expired. Certain financial instruments are recorded at fair value in the consolidated statement of financial position. Refer to note 13 on fair value measurements. Non-derivative financial instruments Non-derivative financial instruments are recognized initially at fair value plus attributable transaction costs, where applicable for financial instruments not classified as fair value through profit or loss. Subsequent to initial recognition, non-derivative financial instruments are classified and measured as described below. Financial assets at fair value through profit or loss Cash and cash equivalents and short-term deposits are classified as financial assets at fair value through profit or loss and are measured at fair value. Cash equivalents are short-term deposits with maturities of up to 90 days at the date of purchase. Short-term deposits consist of investments with maturities from 91 days to one year at the date of purchase. Convertible notes receivable are recorded at fair value through profit or loss. Financial assets at amortized cost Trade and other receivables and are classified as and measured at amortized cost using the effective interest rate method, less impairment losses, if any. Financial assets at fair value through other comprehensive income The Company’s investments in equity marketable securities are designated as financial assets at fair value through other comprehensive income and are recorded at fair value on the trade date with directly attributable transaction costs included in the recorded amount. Subsequent changes in fair value are recognized in other comprehensive income. Non-derivative financial liabilities Accounts payable and accrued liabilities are accounted for at amortized cost, using the effective interest rate method.
Accounting pronouncements	M. Accounting pronouncements New and amended standards and interpretations issued and effective: Adoption of Definition of a Business (Amendments to IFRS 3) The Company has adopted the amendments to IFRS 3 for the first time in the current year. The amendments clarify that while businesses usually have outputs, outputs are not required for an integrated set of activities and assets to qualify as a business. To be considered a business an acquired set of activities and assets must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. The amendments remove the assessment of whether market participants are capable of replacing any missing inputs or processes and continuing to produce outputs. The amendments also introduce additional guidance that helps to determine whether a substantive process has been acquired. The amendments introduce an optional concentration test that permits a simplified assessment of whether an acquired set of activities and assets is not a business. Under the optional concentration test, the acquired set of activities and assets is not a business if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar assets. The amendments are applied prospectively to all business combinations and asset acquisitions for which the acquisition date is on or after January 1, 2020. The amendments were applied to the Company's acquisition of 3 Aces gold project and Snowfield property, where the Company concluded that the acquired set of activities and assets was not a business. Refer to Note 8 for further details. New accounting standards issued but not yet effective: Amendments to IAS 16 - Property, Plant and Equipment: Proceeds before Intended Use The IASB issued an amendment to IAS 16, Property, Plant and Equipment to prohibit the deducting from property, plant and equipment amounts received from selling items produced while preparing an asset for its intended use. Instead, sales proceeds and its related costs must be recognized in profit or loss. The amendment will require companies to distinguish between costs associated with producing and selling items before the item of property, plant and equipment is available for use and costs associated with making the item of property, plant and equipment available for its intended use. The amendment is effective for annual periods beginning on or after January 1, 2022, with earlier application permitted. The amendments apply retrospectively, but only to assets brought to the location and condition necessary for them to be capable of operating in the manner intended on or after the beginning of the earliest period presented in the financial statements in which the Company first applies the amendments. The Company does not expect the adoption of this pronouncement to have a material impact on its consolidated financial statements. Other pronouncements have been issued by the IASB that are not mandatory for the current period and have not been early adopted. These pronouncements are not expected to have a material impact on the Company's consolidated financial statements upon adoption.

The Company recorded a $3.6 million provision within non-trade payables and accrued expenses on the consolidated statements of financial position as at December 31, 2016. In 2017 the Company filed an objection to the reassessment with the appeals division of the tax authorities and paid one-half of the accrued balance while the objection is reviewed. In early 2019, the Company received a decision from the appeals division that the Company’s objection was denied, and the Company filed a notice of appeal with the British Columbia Supreme Court. The Attorney General of Canada replied to the facts and arguments in the Company’s Notice of Appeal and stated its position that the Company’s expenditures did not qualify for the BCMETC program. As at December 31, 2020, the Company is in the discovery process with the Department of Justice and will continue to move the appeal process forward as expeditiously as possible. The Company intends to continue to fully defend its position. As at December 31, 2020, the Canada Revenue Agency (CRA) has withheld $2.0 million of HST credits due to the Company that would fully cover the residual balance, including interest, should the Company be unsuccessful in its challenge.

[1]	During 2016, upon the completion of an audit of the application by tax authorities of the British Columbia Mineral Exploration Tax Credit (“BCMETC”) program, the Company was reassessed $3.6 million, including accrued interest, for expenditures that the tax authority has categorized as not qualifying for the BCMETC program. The Company recorded a $3.6 million provision within non-trade payables and accrued expenses on the consolidated statements of financial position as at December 31, 2016. In 2017 the Company filed an objection to the reassessment with the appeals division of the tax authorities and paid one-half of the accrued balance while the objection is reviewed. In early 2019, the Company received a decision from the appeals division that the Company’s objection was denied, and the Company filed a notice of appeal with the British Columbia Supreme Court. The Attorney General of Canada replied to the facts and arguments in the Company’s Notice of Appeal and stated its position that the Company’s expenditures did not qualify for the BCMETC program. As at December 31, 2020, the Company is in the discovery process with the Department of Justice and will continue to move the appeal process forward as expeditiously as possible. The Company intends to continue to fully defend its position. As at December 31, 2020, the Canada Revenue Agency (CRA) has withheld $2.0 million of HST credits due to the Company that would fully cover the residual balance, including interest, should the Company be unsuccessful in its challenge.
