Disclosure Of Detailed Information About Basis Of Presentation [Abstract]
BASIS OF PRESENTATION [Text Block]	2. These consolidated financial statements have been prepared in accordance with and using accounting policies in full compliance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB") and Interpretations of the International Financial Reporting Interpretations Committee ("IFRIC"), effective for the Company's year ended December 31, 2020. The Board of Directors approved the consolidated financial statements for issue on February 25, 2021. The preparation of consolidated financial statements requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates. On March 31, 2020, the Mexican government declared a national health emergency with extraordinary measures due to the COVID 19 pandemic. Numerous health precautions were decreed, including the suspension of non essential businesses, with only essential services to remain open. As at March 31, 2020 mining did not qualify as an essential service so for the protection of the Company's staff, employees, contractors and communities, the Company suspended its three mining operations in Mexico as of April 1, 2020 as mandated by the Mexican government. The Company retained essential personnel at each mine site during the suspension period to maintain safety protocols, environmental monitoring, security measures and equipment maintenance. Non essential employees were sent home to self-isolate and stay healthy, while continuing to receive their base pay. The suspension of activities ceased in May 2020, when mining was declared an essential business by the Mexican government. The Company implemented plans to minimize the risks of the COVID-19 virus, both to employees and to the business. At each site, Endeavour is following government health protocols and is closely monitoring the pandemic with local health authorities. The Company has posted health advisories to educate employees about the COVID-19 symptoms, best practices to avoid contracting and spreading the virus, and procedures to follow if symptoms are experienced. The Company's long term business could be significantly adversely affected by the effects of the COVID 19 pandemic. The Company cannot accurately predict the impact COVID 19 will have on third parties' ability to meet their obligations with the Company, including due to uncertainties relating to the ultimate geographic spread of the virus, the severity of the disease, the duration of the outbreak, and the length of travel and quarantine restrictions imposed by governments of affected countries. In particular, the continued spread of COVID 19 globally could materially and adversely impact the Company's business including without limitation, employee health, limitations on travel, the availability of industry experts and personnel, on-going restrictions to mining and processing operations and drill programs, and other factors that will depend on future developments beyond the Company's control. In addition, the COVID-19 pandemic could adversely affect the economies and financial markets of many countries (including those in which the Company operates), resulting in an economic downturn that could negatively impact the Company's operating results and ability to raise capital. As of December 31, 2020, the Company held $61.1 million in cash and $70.4 million in working capital, the COVID-19 global pandemic is dynamic and given COVID-19 virus cases continue to rise at a significant rate across Mexico and globally, any future restrictions could have a material effect on the Company's financial position. Management believes there is sufficient working capital to meet the Company's current obligations, however the ultimate duration and severity of the COVID-19 pandemic is uncertain and could impact the financial liquidity of the Company. The Company may be required to raise additional funds through future debt or equity financings in order to carry out its business plans. These consolidated financial statements are presented in the Company's functional currency of US dollars and include the accounts of the Company and its wholly owned subsidiaries: Endeavour Management Corp., Endeavour Gold Corporation S.A. de C.V., EDR Silver de Mexico S.A. de C.V.

Disclosure Of Significant Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES [Text Block]	3. The accounting policies below have been applied consistently to all years presented and by all subsidiaries in the group and no material accounting standards were adopted during the year. The Company has changed its presentation of concentrate treatment and refining costs of sales to presenting as a reduction in revenue. The prior period amounts have also been reclassified. (a) The functional and reporting currency of the Company and its subsidiaries is the US dollar. Transactions in currencies other than an entity's functional currency are recorded at the rates of exchange prevailing on the transaction dates. Monetary assets and liabilities that are denominated in foreign currencies are translated at the rates prevailing at each reporting date. Non-monetary assets and liabilities denominated in foreign currencies that are measured at fair value are retranslated to the functional currency at the exchange rate at the date the fair value was determined. Non-monetary items that are measured in terms of historical costs in a foreign currency are not retranslated. Foreign currency translation differences are recognized in profit or loss. (b) The preparation of consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies, the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and judgments are based on management's knowledge of the relevant facts and circumstances at the time, having regard to prior experience, and are continually evaluated. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. Actual results could differ materially from those estimates. Significant areas requiring the use of management judgment relate to the determination of mineralized reserves and resources, plant and equipment useful lives, estimating the fair values of financial instruments and derivatives, impairment of non-current assets, reclamation and rehabilitation provisions, recognition of deferred tax assets, valuations in business combinations and assumptions used in determining the fair value of share-based compensation. Significant areas requiring the use of management estimates relate to the valuation of accounts receivable, inventory, mineral property, plant and equipment, impairment of non-current assets, provision for reclamation and rehabilitation, share capital and income taxes. Critical judgments and estimates in applying policies that have the most significant effect on the amounts recognized in the consolidated financial statements include the following: Determination of ore reserves and resources Judgments about the amount of product that can be economically and legally extracted from the Company's properties are made by management using a range of geological, technical and economic factors, history of conversion of mineral deposits to proven and probable reserves as well as data regarding quantities, grades, production techniques, recovery rates, production costs, commodity prices and exchange rates. This process may require complex and difficult geological judgments to interpret the data. The Company uses qualified persons (as defined by the Canadian Securities Administrator's National Instrument 43-101) to compile this data. Changes in the judgments surrounding reserves and resources may impact the carrying value of mineral properties, plant and equipment (Note 10), reclamation and rehabilitation provisions (Note 14), recognition of deferred income tax amounts (Note 23), and depreciation, depletion and amortization (Note 8,9,10). Estimating the quantity and /or grade of reserves and resources requires the size, shape and depth of ore bodies or fields to be determined by analyzing geological data such as drilling samples. Following this, the quantity of ore that can be extracted in an economical manner is calculated using data regarding the life of mine plans and forecast sales prices (based on current and long-term historical average price trends). Changes in estimates can be the result of estimated future production differing from previous forecasts of future production, expansion of mineable ore through exploration activities, differences between estimated and actual costs of mining and differences in the commodity price used in the estimation of mineable ore. Review of asset carrying values and assessment of impairment (accounting policy Note 3h) Management applies significant judgment in assessing each cash-generating unit and assets for the existence of indicators of impairment or impairment reversal at the reporting date. Internal and external factors are considered in assessing whether indicators are present that would necessitate impairment testing. Significant assumptions regarding commodity prices, operating costs, capital expenditures and discount rates are used in determining whether there are any indicators of impairment. These assumptions are reviewed regularly by senior management and compared, when applicable, to relevant market consensus views. If an indicator of impairment ore reversal exists, the asset's recoverable amount is estimated. The recoverable amount is the greater of fair value less costs of disposal and value in use. The determination of fair value less costs of disposal and value in use requires management to make estimates and assumptions about expected production and sales volumes, metal prices, ore tonnage and grades, recoveries, operating costs, future capital expenditures and appropriate discount rate for future cash flows. The estimates and assumptions are subject to risk and uncertainty, and as such there is the possibility that changes in circumstances will alter these projections, which may impact the recoverable amount of the assets. In such circumstances, some or all of the carrying value of the assets may be further impaired or the impairment charge reduced with the impact recorded in profit or loss. Achievement of commercial production (accounting policy Note 3g). Once a mine reaches the operating levels intended by management, depreciation of capitalized costs begins. Significant judgment is required to determine when certain of the Company's assets reach this level. Management considers several factors including: completion of a reasonable period of commissioning; consistent operating results achieved at a pre-determined level of design capacity and indications exist that this level will continue; mineral recoveries at or near expected levels; and the transfer of operations from development personnel to operational personnel has been completed. Estimation of the amount and timing of reclamation and rehabilitation costs (accounting policy Note 3j) Accounting for restoration requires management to make estimates of the future costs the Company will incur to complete the reclamation and rehabilitation work required to comply with existing laws, regulations and agreements in place at each mining operation and any environmental and social principles the Company is in compliance with. The calculation of the present value of these costs also includes assumptions regarding the timing of reclamation and rehabilitation work, applicable risk-free interest rate for discounting those future cash flows, inflation and foreign exchange rates and assumptions relating to probabilities of alternative estimates of future cash flows. Actual costs incurred may differ from those amounts estimated. Also, future changes to environmental laws and regulations could increase the extent of reclamation and rehabilitation work required to be performed by the Company. Increase in future costs could materially impact the amounts charged to operations for reclamation and rehabilitation. Taxes (Note 23) Judgment is required in determining the recognition and measurement of deferred income tax assets and liabilities on the balance sheet. In the normal course of business, the Company is subject to assessment by taxation authorities in various jurisdictions. These authorities may have different interpretations of tax legislation or tax agreements than those applied by the Company in computing current and deferred income taxes. These different interpretations may alter the timing or amounts of taxable income or deductions. Final taxes payable and receivable are dependent on many factors, including outcomes of tax litigation and resolution of disputes. The resolution of these uncertainties may result in adjustments to the Company's tax assets and liabilities. Management assesses the likelihood and timing of taxable earnings in future periods in recognizing deferred income tax assets. Estimates of future taxable income are based on forecasted cash flows using life of mine projections and the application of existing tax laws in each jurisdiction. To the extent that future cash flows and taxable income differ significantly from estimates, the ability of the Company to realize the net deferred income tax assets recorded at the balance sheet date could be impacted. In addition, future changes to tax laws could limit the ability of the Company to obtain tax deductions in future periods from deferred income tax assets. Deferred income tax assets are disclosed in Note 23. Inventory (Note 6) In valuing inventories at the lower of cost and net realizable value, the Company makes estimates in determining the net realizable price and in quantifying the contained metal in finished goods and work in progress. (c) Cash and cash equivalents consist of deposits in banks and highly liquid investments with an original maturity at the date of the purchase of no more than ninety days, or that are readily convertible into cash. (d) Marketable securities include investments in shares of companies and other investments capable of reasonably prompt liquidation. Share investments are measured at fair value through profit and loss and carried at fair value. Unrealized gains and losses are recognized in profit or loss. (e) Work-in-process inventories, including ore stockpiles, are valued at the lower of production cost and net realizable value, after an allowance for further processing costs. Finished goods inventory, characterized as doré bars or concentrate, is valued at the lower of production cost and net realizable value. Materials and supplies are valued at the lower of cost and replacement cost. Similar inventories within the consolidated group are measured using the same method, and the reversal of previous write-downs to net realizable value is required when there is a subsequent increase in the value of inventories. (f) Intangible assets are initially recognized at cost if acquired externally, or at fair value if acquired as part of a business combination and have a useful life of greater than one year. Intangible assets which have finite useful lives are measured at cost less accumulated amortization and accumulated impairment. Intangible assets that are assessed as having a finite useful life are amortized over their useful life on a straight-line basis from the date they become available for use and are tested for impairment if indications exist that they may be impaired. The useful life is determined using the period of the underlying contract or the period over which the intangible asset can be expected to be used. (g) Mineral properties, plant and equipment are stated at cost less accumulated depreciation, depletion and accumulated impairment losses. The cost of mineral properties, plant and equipment items consists of the purchase price, any costs directly attributable to bringing the asset to the location and condition necessary for its intended use and an initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located. Mineral properties include direct costs of acquiring properties (including option payments) and costs incurred directly in the development of properties once the technical feasibility and commercial viability has been established. Development costs relating to specific properties are capitalized once management determines a property will be developed. A development decision is made based upon consideration of project economics, including future metal prices, reserves and resources, and estimated operating and capital costs. Capitalization of costs incurred, and proceeds received from the sale of goods produced during the testing phase ceases when the property is capable of operating at levels intended by management. Exploration and evaluation costs are those costs required to acquire a mineral property and determine commercial feasibility. These costs include costs to establish an initial mineral resource and determine whether inferred mineral resources can be upgraded to measured and indicated mineral resources and whether measured and indicated mineral resources can be converted to proven and probable reserves. The Company recognizes acquisition costs for exploration and evaluation properties as assets when acquired as part of a business combination or asset purchase. All other exploration and evaluation costs are expensed as incurred until the technical feasibility and commercial viability of the property has been established and a development decision has been made. Capitalized exploration and evaluation costs for a project are classified as such until the project demonstrates technical feasibility and commercial viability. Upon demonstrating technical feasibility and commercial viability, and subject to an impairment analysis, capitalized exploration and evaluation costs are transferred to mineral property costs within mineral properties, plant and equipment. Technical feasibility and commercial viability generally coincide with the establishment of proven and probable reserves; however, this determination may be impacted by management's assessment of certain modifying factors. Where an item of plant and equipment comprises major components with different useful lives, the components are accounted for as separate items of plant and equipment and amortized separately over their useful lives. Plant and equipment are recorded at cost and amortized using either the straight-line method at rates varying from 5% to 30% annually or amortized on a units of production method, based on proven and probable reserves. The accumulated costs of mineral properties that are developed to the stage of commercial production are amortized using the units of production method, based on proven and probable reserves (as defined by National Instrument 43-101). The Company conducts an annual assessment of the residual balances, useful lives and depreciation methods being used for mineral properties, plant and equipment and any changes arising from the assessment are applied by the Company prospectively. (h) The Company's tangible assets are reviewed for indications of impairment or reversal of a previous impairment at each financial statement date. If an indicator of impairment or reversal exists, the asset's recoverable amount is estimated. An impairment loss is recognized when the carrying amount of an asset, or its cash-generating unit, exceeds its recoverable amount. A cash-generating unit is the smallest identifiable group of assets that generates cash flows that are largely independent of the cash flows from other assets or groups of assets. Impairment losses are recognized in profit and loss for the period. The recoverable amount is the greater of fair value less costs of disposal and value in use. In assessing value in use, the 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. For an asset that does not generate largely independent cash inflows, the recoverable amount is determined for the cash-generating unit to which the asset belongs. An impairment loss is reversed if there is an indication that there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset's carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized. Management periodically reviews the carrying values of its exploration and evaluation assets with internal and external mining related professionals. A decision to abandon, reduce or expand a specific project is based upon many factors including general and specific assessments of reserves, forecast future metal prices, forecast future costs of exploring, developing and operating a producing mine, expiration term and ongoing expense of maintaining leased mineral properties and the general likelihood that the Company will continue exploration. The Company does not set a pre-determined holding period for properties with unproven reserves. However, properties which have not demonstrated suitable mineral concentrations at the conclusion of each phase of an exploration program are re-evaluated to determine if future exploration is warranted and their carrying values are recoverable. If any area of interest is abandoned or it is determined that its carrying value cannot be supported by future production or sale, the related costs are recognized in profit or loss in the period of abandonment or determination that the carrying value exceeds its fair value. The amounts recorded as mineral properties represent costs incurred to date and do not necessarily reflect present or future values. (i) Effective January 1, 2019, at inception of a contract, the Company assesses whether a contract is or contains a lease. A contract is or contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Company recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of use asset is initially measured at cost, which is composed of: The amount of the initial measurement of the lease liability Any lease payments made at or before the commencement date Any indirect costs incurred An estimate of costs to dismantle and remove the underlying asset or to restore the site on which the asset is located Less any incentives received from the lessor The right-of-use asset is depreciated using the straight-line method from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term. Estimated useful lives of right-of-use assets are determined on the same basis as those of property and equipment. The lease liability 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. Lease payments included in the measurement of the lease liability are composed of: Fixed payments, including in-substance fixed payments Variable lease payments that depend on an index or rate, initially measured using the index or rate as at the commencement date Amounts expected to be payable under a residual value guarantee; and The exercise price under a purchase option that the Company is reasonably certain to exercise, lease payments in an optional renewal period if the Company is reasonably certain to exercise an extension option, and penalties for early termination of a lease unless the Company is reasonably certain not to terminate early. The lease payments exclude variable payments which are dependent on external factors other than an index or a rate. These variable payments are recognized directly in profit or loss. The lease liability is remeasured when there is a change in future lease payments arising from a change in an index or rate, if there is a change in the Company's estimated amount expected to be 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 liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use asset or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero. The Company has elected not to recognize right-of-use assets and lease liabilities for short-term leases that have a lease term of 12 months or less and leases of low-value assets. The lease payments associated with these leases are expensed on a straight-line basis over the lease term. (j) The Company recognizes provisions for statutory, contractual, constructive or legal obligations associated with the decommissioning and reclamation of mineral properties, plant and equipment, when those obligations result from the acquisition, construction, development or normal operation of the assets. A liability is recognized at the time environmental disturbance occurs and the resulting costs are capitalized to the corresponding asset. The provision for reclamation and rehabilitation obligations is estimated using expected cash flows based on engineering and environmental reports prepared by third-party industry specialists and is discounted at a pre-tax rate specific to the liability. The capitalized amount is amortized on the same basis as the related asset. In subsequent periods, the liability is adjusted for any changes in the amount or timing of the estimated future cash costs, changes in the discount or inflation rates and for the accretion of discounted underlying future cash flows. The unwinding of the effect of discounting the provision is recorded as a finance cost in profit or loss for the period. (k) Revenue is generated from the sale of refined silver and gold or from the sale of these metals contained in doré or concentrate. Revenue for doré is recorded in the consolidated statement of comprehensive income gross of treatment and refining costs paid to counterparties under the terms of the sales agreements. Revenue for concentrate is recorded in the consolidated statement of comprehensive income net of treatment and refining costs paid to counterparties under the terms of the sales agreements. Revenue is recognized when control of the metal is transferred to the customer in an amount that reflects the consideration the Company expects to receive in exchange for the metals. In determining whether the Company has satisfied its performance obligation, it considers the indicators of the transfer of control, which include but are not limited to, whether: the Company has a present right to payment; the customer has a legal title to the asset; the Company has transferred physical possession of the asset to the customer; and the customer controls the risks and rewards of ownership of the asset. Revenue from metals in doré The refiners who receive doré from the Company refine the materials on the Company's behalf. The refiners transfer the refined product to our customers according to the Company's instructions. Refined metals are sold at spot prices with sales proceeds collected upon or within several days of the completion of the sales transaction. Revenue from sale of doré is recognized at the time a metal sale is executed and the Company has irrevocably directed the refiner to deliver the refined metal to the customer. Revenue from metals in concentrate Metals in concentrate are sold under pricing arrangements where final prices are determined by market prices subsequent to the date of sale. Revenue from the sale of concentrates is provisionally priced at the date control transfers. On transfer, the Company recognizes revenue on a provisional basis based on current prices and at each period end, re-estimated prices based on forward market prices for the estimated month of settlement. The final selling price is subject to movements in metal prices up to the final settlement date. Revenue is initially recognized based on the estimated mineral content then adjusted to final settlement adjustments. Final settlement periods range from two to six months after delivery of the product. Variations between the sales price recorded at the initial recognition date and the actual final sales price at the settlement date, caused by changes in market metal prices, results in an embedded derivative in the related trade accounts receivable. For each reporting period until final settlement, forward market prices are used to record revenue. The embedded derivative is recorded at fair value each period until final settlement occurs, with changes in fair value classified as an adjustment to revenue. (l) The Company has a share option plan and performance share unit plan which are described in Note 15(c) and Note 15(d) respectively. Equity-settled share-based payment awards to employees are measured by reference to the fair value of the equity instruments granted and are charged over the vesting period using the graded vesting method. The amount recognized as an expense is adjusted to reflect the actual number of share options for which the related service and vesting conditions are met. Equity-settled share-based payment awards to non-employees are measured at the fair value of the goods or services received as the goods or services are received, unless that fair value cannot be measured reliably, in which case they are measured by reference to the fair value of the equity instrument. The offset is credited to contributed surplus. Consideration received on the exercise of stock options is recorded as share capital and the related contributed surplus is transferred to share capital. For those options that expire or are forfeited after vesting, the amount previously recorded in contributed surplus is transferred to deficit. Share-based compensation expense relating to cash-settled awards, including deferred share units and share appreciation rights which are described in Note 15(e) and Note 15(f), is recognized over the vesting period of the units based on the fair market value of the units. As these awards will be settled in cash, the expense and liability are adjusted each reporting period for changes in the fair value. (m) Income tax expense (recovery) comprises current and deferred tax. It is recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or other comprehensive income. Current tax comprises the expected tax payable or receivable on the taxable income or loss for the year and any adjustments to the tax payable or receivable in respect of previous years. The amount of current tax payable or receivable is the is the best estimate of the tax amount expected to be paid or received that reflects uncertainty relate to income taxes, if any. It is measured using tax rates enacted or substantively enacted at the reporting date. Current tax also includes any tax arising from dividends. The Company follows the asset and liability method of accounting for deferred income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and tax losses carried forward. Deferred tax assets and liabilities are measured using substantively enacted or enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in profit or loss in the period that includes the substantive enactment date. Deferred tax assets are recognized to the extent their recovery is considered probable based on their term to expiry and estimates of future taxable income. 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; such reductions are reversed when the probability of future taxable profits improve. (n) Basic earnings per share is computed by dividing the net earnings (loss) available to common shareholders by the weighted average number of shares (o) On a business combination, the acquisition method of accounting is used, whereby the purchase consideration is allocated to the identifiable assets, liabilities and contingent liabilities (identifiable net assets) based on fair value at the date of acquisition. When the cost of acquisition exceeds the fair values attributable to the Company's share of identifiable net assets, the difference is treated as purchased goodwill. If the fair value attributable to the Company's share of the identifiable net assets exceeds the cost of acquisition, the difference is immediately recognized in the profit or loss. Incremental costs related to acquisitions are expensed as incurred. Determination of the fair value of assets acquired and liabilities assumed and resulting goodwill, if any, requires that management make estimates based on the information provided by the acquiree. Changes to the provisional values of assets acquired and liabilities assumed, deferred income taxes and resulting goodwill, if any, will be adjusted when the final measurements are determined (within one year of the acquisition date). When purchase consideration is contingent on future events, the initial cost of the acquisition recorded includes an estimate of the fair value of the contingent amounts expected to be payable in the future. Changes to the estimated fair value of contingent consideration subsequent to the acquisition date are recorded in profit or loss. (p) The Company recognizes financial assets and financial liabilities on the date the Company becomes party to the contractual provisions of the instruments. On initial recognition, all financial assets and financial liabilities are recorded at fair value, net of attributable transaction costs, except for financial assets and liabilities classified as fair value through profit and loss ("FVTPL"). Transaction costs of financial assets and liabilities classified as FVTPL are expensed in the period in which they are incurred. A financial asset is derecognized either when the Company has transferred substantially all the risks and rewards of ownership of the financial assets or when cash flows expire. A financial liability is derecognized when the obligation specified in the contract is discharged, cancelled or expired. On initial recognition, the Company classifies and measures financial assets as either fair value through profit and loss ("FVTPL"), fair value through other comprehensive income ("FVTOCI") or amortized cost. Subsequent measurement of financial assets depends on the classifications of such assets. The basis of classification depends on an entity's business model and the contractual cash flows of the financial asset. Amortized cost Financial assets that meet the following conditions are measured subsequently at amortized cost: The financial asset is held within a business model whose objective is to hold financial assets in order to collect contractual cash flows, and The contractual terms of the financial asset provide cash flows on specified dates that are solely payments of principal and interest on the principal amount outstanding The amortized cost of a financial asset is the amount at which the financial asset is measured at initial recognition minus the principal repayments, plus the cumulative amortization using the effective interest method of any difference between the initial amount and the maturity amount, adjusted for any loss allowance. Interest income is recognized using the effective interest method. Fair value through other comprehensive income Financial assets that meet the following conditions are measured subsequently at amortized cost: The financial asset is held within a business model whose objective is achieved by both collecting the contractual cash flows and selling financial assets, and The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding Investments in equity instruments at FVTOCI are initially recognized at fair value. Subsequently, they are measured at

The fair values of Level 1 marketable securities are determined based on a market approach reflecting the closing price of each particular security at the reporting date. The closing price is a quoted market price obtained from the exchange that is the principal active market for the particular security, being the market with the greatest volume and level of activity for the assets. For Level 2 marketable securities, where there is not yet an active market for the securities as a listing on an exchange is pending, the fair value is determined based on the most recent observable transaction for those securities. Changes in fair value of marketable securities are recognized in profit or loss.

(i) Cerro Marquez - Las Palcas In October 2016, the Company entered into an option agreement with Minera Cerro Marquez to acquire 100% interest in the Las Palcas project in Santiago, Chile for a total of $2.5 million to be paid over a four year period with the final payment of $2.3 million due in October 2020. The interest is subject to a net smelter return ("NSR") royalty of 2% with the Company entitled purchase the royalty for $1.2 million for each 1% of the NSR. In October 2020, the Company signed an addendum agreement and paid $0.2 to defer the final payment to October 2021. The addendum also extended by one year the Company's commitment to spend $1.5 million on exploration expenses in the property within forty-eight months from the date of the option agreement. Aida Properties In July 2018, the Company entered into an option agreement to acquire 100% interest in the Aida properties: Patricia II, Patricia III and SLM Ignacia located in Chile for a total of $3.2 million to be paid over a five year period. The properties are subject to a 2% NSR with the right to buy the NSR for each of the properties for $2.0 million. Payments totaling $0.4 million for 2018 and 2019 have been made but the 2020 payment has been postponed until the Company receives certain permits. Paloma Properties In December 2018, the Company signed an option agreement to acquire up to a 70% interest in the Paloma project in Antofagasta province, Chile. The Company can acquire its initial 51% interest by paying $0.75 million and spending $5.0 million over five years with the final payment due in 2023, followed by a second option to acquire 70% by completing a Preliminary Economic Assessment and a Preliminary Feasibility Study. The property is subject to a 2% NSR. (j) The Company has entered into other non-material option agreements on exploration properties in Mexico and Chile. Management believes the Company has diligently investigated rights of ownership of all its mineral properties to a level which is acceptable by prevailing industry standards with respect to the current stage of development of each property in which it has an interest and, to the best of its knowledge, all agreements relating to such ownership rights are in good standing. However, all properties may be subject to prior claims, agreements or transfers, and rights of ownership may be affected by undetected defects.

Disclosure Of Impairment Of Non Current Assets [Abstract]
IMPAIRMENT OF NON-CURRENT ASSETS [Text Block]	11. IMPAIRMENT OF NON-CURRENT ASSETS The recoverable amounts of the Company's CGUs, which include mining properties, plant and equipment are determined at the end of each reporting period, if impairment indicators are identified. In previous years, commodity price declines, changes in tax legislation and a reduction in reserves and resources led the Company to determine there were impairment indicators and assessed the recoverable amounts of its CGUs. The recoverable amounts were based on each CGUs future cash flows expected to be derived from the Company's mining properties and represent each CGUs value in use. The cash flows were determined based on the life-of-mine after-tax cash flow forecast which incorporates management's best estimates of future metal prices, production based on current estimates of recoverable reserves and resources, exploration potential, future operating costs and non-expansionary capital expenditures discounted at risk adjusted rates based on the CGUs weighted average cost of capital. At December 31, 2020, the Company recognized a $2,576 reversal of a previous impairment of the Guanaceví Mine. An increase in the reserve and resource estimate and increase in precious metal prices were considered to be indicators of an impairment reversal. The updated Guanaceví mine plan, with updated assumptions and estimates, calculated on a discounted cash flow basis using a 6.1% discount rate, resulted in significantly higher cash flows compared to the Company's previous estimates. Accordingly, the Company reversed the 2013 Guanaceví CGU impairment, limited to the carrying amount had no impairment been recognized in prior periods, net of depletion and amortization which would have been recognized in prior periods. At December 31, 2020, the Company recognizes an impairment of the El Compas Mine Project. A decrease in the resource estimate as at December 31, 2020 was considered to be an indicator of an impairment. The carrying value related to the El Compas CGU, excluding working capital and reclamation provision, was $5,972 which was greater than its estimated recoverable amount of $2,972, calculated on a discounted cash flow basis using a 6.1% discount rate. The Company considers use of its internal discounted cash flow economic models as a proxy for the calculation of fair value in use. Based on the above assessment, the Company recorded an impairment charge related to the El Compas CGU of $3,000. The recoverable amounts of the Guanaceví and El Compas mines were determined based on their value in use, estimated utilizing a discounted cash flow model using a 6.1% discount rate. Assumptions used to determine the recoverable amounts of the CGUs include metal prices, changes in the amount of recoverable reserves and resources, production costs, future capital expenditures and discount rates. The discounted cash flow models are a Level 3 measurement in the fair value hierarchy. For a discounted cash flow model, any modest decrease in any one key assumption in isolation could cause the estimated recoverable amount to be less than or equal to the net carrying value.

Provision For Reclamation And Rehabilitation [Abstract]
PROVISION FOR RECLAMATION AND REHABILITATION [Text Block]	14. PROVISION FOR RECLAMATION AND REHABILITATION The Company's environmental permit requires that it reclaim certain land it disturbs during mining operations. Significant reclamation and closure activities include land rehabilitation, decommissioning of buildings and mine facilities, ongoing care and maintenance and other costs. Although the ultimate amount of the reclamation and rehabilitation costs to be incurred cannot be predicted with certainty, the total undiscounted amount of probability weighted estimated cash flows required to settle the Company's estimated obligations is $2,555 for the Guanaceví mine, $2,174 for the Bolañitos mine, $5,132 for the El Cubo mine and $167 for the El Compas development project. The timing of cash flows has been estimated based on the mine lives using current reserves and the present value of the probability weighted future cash flows. The model assumes a risk-free rate specific to the liability of 2.25% for Guanaceví and Bolañitos, and 6.2% for El Cubo and El Compas and with an estimated inflation rate of 2.0% for Guanaceví and Bolañitos and 4.0% for El Cubo and El Compas.

The weighted-average fair values of stock options granted and the assumptions used to calculate the related compensation expense have been estimated using the Black-Scholes Option Pricing Model with the following assumptions: Year Ended Year Ended Weighted-average fair value of option in CAN$ $1.02 $1.57 Risk-free interest rate 1.08% 1.75% Expected dividend yield 0% 0% Expected stock price volatility 61% 64% Expected option life in years 3.82 3.83 Option pricing models require the input of highly subjective assumptions. The expected life of the options considered such factors as the average length of time similar option grants in the past have remained outstanding prior to exercise, expiry or cancellation and the vesting period of options granted. Volatility was estimated based on average daily volatility based on historical share price observations over the expected term of the option grant. Changes in the subjective input assumptions can materially affect the estimated fair value of the options. The Company amortizes the fair value of stock options on a graded basis over the respective vesting period of each tranche of stock options awarded. As at December 31, 2020, the unvested share option expense not yet recognized was $637 (December 31, 2019 - $524) which is expected to be recognized over the next 21 months.

Under the PSU plan, vested PSUs are redeemable, at the election of the Board of Directors in its discretion, for Common Shares , a cash payment equal to the market value of a Common Share as of the redemption date, or a combination of cash and Common Shares. The PSUs granted are subject to a performance payout multiplier between 0% and 200% based on the Company's total shareholder return at the end of a three-year period, relative to the Company's total shareholder return peer group. The maximum number of common shares authorized for issuance from treasury under the PSU plan is 2,000,000. Year Ended Year Ended December 31, 2020 December 31, 2019 Number of units Number of units Outstanding, beginning of year 1,219,000 616,000 Granted 882,000 603,000 Cancelled (296,000 ) — Outstanding, end of period 1,805,000 1,219,000 There were 882,000 PSUs granted during the year ended December 31, 2020 (December 31, 2019 - 603,000).

INCOME TAXES [Text Block]	23. INCOME TAXES (a) Tax Assessments Minera Santa Cruz y Garibaldi SA de CV ("MSCG"), a subsidiary of the Company, received a MXN 238 million assessment on October 12, 2010 by Mexican fiscal authorities for failure to provide the appropriate support for certain expense deductions taken in MSCG's 2006 tax return, failure to provide appropriate support for loans made to MSCG from affiliated companies, and deemed an unrecorded distribution of dividends to shareholders, among other individually immaterial items. MSCG immediately initiated a Nullity action and filed an administrative attachment to dispute the assessment. In June 2015, the Superior Court ruled in favour of MSCG on a number of the matters under appeal; however, the Superior Court ruled against MSCG for failure to provide appropriate support for certain deductions taken in MSCG's 2006 tax return. In June 2016, the Company received a MXN 122.9 million ($6,200) tax assessment based on the June 2015 ruling. The 2016 tax assessment comprised of MXN 41.8 million owed ($2,100) in taxes, MXN 17.7 million ($900) in inflationary charges, MXN 40.4 million ($2,000) in interest and MXN 23.0 million ($1,200) in penalties. The 2016 tax assessment was issued for failure to provide the appropriate support for certain expense deductions taken in MSCG's 2006 tax return and failure to provide appropriate support for loans made to MSCG from affiliated companies. The MXN 122.9 million assessment includes interest and penalties. If MSCG agrees to pay the tax assessment, or a lesser settled amount, it is eligible to apply for forgiveness of 100% of the penalties and 50% of the interest. The Company filed an appeal against the June 2016 tax assessment on the basis certain items rejected by the courts were included in the new tax assessment, and a number of deficiencies exist within the assessment. Since issuance of the assessment interest charges of MXN 9.1 million ($500) and inflationary charges of MXN 13.7 million ($700) has accumulated. Included in the Company's consolidated financial statements, are net assets of $595, including $42 in cash, held by MSCG. Following the Tax Court's rulings, MSCG is in discussions with the tax authorities with regards to the shortfall of assets within MSCG to settle its estimated tax liability. An alternative settlement option would be to transfer the shares and assets of MSCG to the tax authorities. As of December 31, 2020, the Company's income tax payable includes an allowance for transferring the shares and assets of MSCG amounting to $595. The Company continues to assess MSCG's settlement options based on on-going court proceedings and discussion with the tax authorities. The Company continues to assess that it is probable that its appeal should prevail, and the maximum estimated exposure is the amount of the above allowance. Compania Minera Del Cubo SA de CV ("Cubo"), a subsidiary of the Company, received a MXN 58.5 million ($2,900) assessment in 2019 by Mexican fiscal authorities for alleged failure to provide the appropriate support for depreciation deductions taken in the Cubo 2016 tax return and denied eligibility of deductions of certain suppliers. The tax assessment consists of MXN 24.1 million ($1,200) for taxes, MXN 21.0 million ($1,100) for penalties, MXN 10.4 million ($500) for interest and MXN 3.0 million ($100) for inflation. At the time of the tax assessment the Cubo entity had and continues to have sufficient loss carry forwards which would be applied against the assessed difference of taxable income. The Mexican tax authorities did not consider these losses in the assessment. Due to the denial of certain suppliers for income tax purposes in the Cubo assessment, the invoices from these suppliers have been assessed as ineligible for refunds of IVA paid on the invoices. The assessment includes MXN 14.7 million ($700) for re-payment of IVA (value added taxes) refunded on these supplier payments. In the Company's judgement the suppliers and invoices meet the necessary requirements to be deductible for income tax purposes and the recovery of IVA. The Company has filed an administrative appeal related to the 2016 Cubo Tax assessment. Cubo has provided a lien on certain El Cubo mining concessions during the appeal process. Since issuance of the assessment interest charges of MXN 9.9 million ($500) and inflationary charges of MXN 1.6 million ($100) has accumulated. The Company continues to assess that it is probable that its appeal will prevail, and no provision is required in respect of the Cubo assessment.

FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS [Text Block]	24. FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS (a) Financial assets and liabilities As at December 31, 2020, the carrying and fair values of the Company's financial instruments by category are as follows: Fair value through profit or loss Amortized Carrying Fair value $ $ $ $ Financial assets: Cash and cash equivalents — 61,083 61,083 61,083 Other Investments 4,767 — 4,767 4,767 Trade and other receivables 8,755 11,389 20,144 20,144 Total financial assets 13,522 72,472 85,994 85,994 Financial liabilities: Accounts payable and accrued liabilites 6,389 21,375 27,764 27,764 Loans payable — 9,672 9,672 9,672 Total financial liabilities 6,389 31,047 37,436 37,436 Fair value measurements Fair value hierarchy 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 and volatility measurements used to value option contracts), 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. Level 1: Other investments are comprised of marketable securities. When there is an active market are determined based on a market approach reflecting the closing price of each particular security at the reporting date. The closing price is a quoted market price obtained from the exchange that is the principal active market for the particular security. As a result, $4,270 of these financial assets have been included in Level 1 of the fair value hierarchy. Deferred share units are determined based on a market approach reflecting the Company's closing share price. Level 2: The Company determines the fair value of the embedded derivatives related to its trade receivables based on the quoted closing price obtained from the silver and gold metal exchanges. Other investments are comprised of marketable securities. When there is not an active market as a listing on an exchange is pending, the fair value is determined based on the most recently observable transaction for those securities. As a result, $497 of these financial assets have been included in Level 2 of the fair value hierarchy. Level 3: The Company has no assets or liabilities included in Level 3 of the fair value hierarchy There were no transfers between levels 1, 2 and 3 during the year ended December 31, 2020. Assets and liabilities as at December 31, 2020 measured at fair value on a recurring basis include: Total Level 1 Level 2 Level 3 $ $ $ $ Financial assets: Investments 4,767 4,270 497 — Trade and other receivables 20,144 11,389 8,755 — Total financial assets 24,911 15,659 9,252 — Financial liabilities: Deferred share units 6,389 6,389 — — Total financial liabilities 6,389 6,389 — — (b) Financial Instrument Risk Exposure and Risk Management The Company is exposed in varying degrees to a variety of financial instrument related risks. The Board approves and monitors the risk management process. The types of risk exposure and the manner in which such exposures are managed is outlined as follows: Credit Risk The Company is exposed to credit risk on its bank accounts and accounts receivable. Credit risk exposure on bank accounts is limited through maintaining the Company's balances with high-credit quality financial institutions, maintaining investment policies, assessing institutional exposure and continual discussion with external advisors. Value added tax ("IVA") receivables are generated on the purchase of supplies and services to produce silver and gold, which are refundable from the Mexican government. Trade receivables are generated on the sale of concentrate inventory to reputable metal traders. The carrying amount of financial assets represents the Company's maximum credit exposure. Below is an aged analysis of the Company's receivables: Carrying Gross Carrying Gross amount impairment amount impairment December 31, 2020 December 31, 2019 Less than 1 month $ 10,629 $ — $ 10,048 $ — 1 to 3 months 7,491 — 4,083 — 4 to 6 months 239 — 1,109 — Over 6 months 4,512 — 9,758 151 Total accounts receivable $ 22,871 $ — $ 24,998 $ 151 At December 31, 2020, 75% of the receivables that were outstanding greater than one month were comprised of IVA and tax receivables in Mexico (December 31, 2019 - 93%) and 23% of the receivables outstanding greater than one month are pending finalizations of concentrate sales. At December 31, 2020, an impairment loss of $nil relates to IVA receivable claims from prior years written off during the year (December 31, 2019 - $151). Liquidity Risk Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they come due. We manage our liquidity risk by continually monitoring forecasted and actual cash flows. We have in place a planning and budgeting process to help determine the funds required to support our normal operating requirement and development plans. We aim to maintain sufficient liquidity to meet our short term business requirements, taking into account our anticipated cash flows from operations, our holdings of cash and cash equivalents, and our committed and anticipated liabilities. The following table summarizes the remaining contractual maturities of the Company's financial liabilities and operating and capital commitments at December 31, 2020: Less than 1 to 3 4 to 5 Over 5 1 year years years years Total $ $ $ $ $ Accounts payable and accrued liabilities 27,764 27,764 Income taxes payable 3,038 3,038 Loans payable 3,582 5,598 492 9,672 Lease liabilities 173 287 247 387 1,094 Provision for reclamation and rehabilitation — 4,673 1,978 2,225 8,876 Capital expenditure commitments 955 955 Operating leases 135 219 219 283 856 Total contractual obligations 35,647 10,777 2,936 2,895 52,255 Market Risk Significant market related risks to which the Company is exposed consist of foreign currency risk, commodity price risk and equity price risk. Foreign Currency Risk The US dollar equivalents of financial assets and liabilities denominated in currencies other than the US dollar as at December 31 st December 31, 2020 December 31, 2019 Canadian Dollar Mexican Peso Canadian Dollar Mexican Peso Financial assets $ 9,383 $ 18,920 $ 923 $ 21,301 Financial liabilities (8,512 ) (14,036 ) (3,562 ) (12,098 ) Net financial assets (liabilities) $ 871 $ 4,884 $ (2,639 ) $ 9,203 Of the financial assets listed above, $3,192 (2019 - $25) represents cash and cash equivalents held in Canadian dollars and $4,590 (2019 - $3,140) represents cash held in Mexican Pesos. The remaining cash balance is held in US dollars. As at December 31, 2020, with other variables unchanged, a 5% strengthening of the US dollar against the Canadian dollar would reduce net earnings by $41 due to these financial assets and liabilities. As at December 31, 2020, with other variables unchanged, a 5% strengthening of the US dollar against the Mexican peso would decrease net earnings by $233 due to these financial assets and liabilities.

Disclosure Of Significant Accounting Policies [Abstract]
Currency Translation [Policy Text Block]	(a) The functional and reporting currency of the Company and its subsidiaries is the US dollar. Transactions in currencies other than an entity's functional currency are recorded at the rates of exchange prevailing on the transaction dates. Monetary assets and liabilities that are denominated in foreign currencies are translated at the rates prevailing at each reporting date. Non-monetary assets and liabilities denominated in foreign currencies that are measured at fair value are retranslated to the functional currency at the exchange rate at the date the fair value was determined. Non-monetary items that are measured in terms of historical costs in a foreign currency are not retranslated. Foreign currency translation differences are recognized in profit or loss.
Use of estimates and judgments [Policy Text Block]	(b) The preparation of consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies, the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and judgments are based on management's knowledge of the relevant facts and circumstances at the time, having regard to prior experience, and are continually evaluated. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. Actual results could differ materially from those estimates. Significant areas requiring the use of management judgment relate to the determination of mineralized reserves and resources, plant and equipment useful lives, estimating the fair values of financial instruments and derivatives, impairment of non-current assets, reclamation and rehabilitation provisions, recognition of deferred tax assets, valuations in business combinations and assumptions used in determining the fair value of share-based compensation. Significant areas requiring the use of management estimates relate to the valuation of accounts receivable, inventory, mineral property, plant and equipment, impairment of non-current assets, provision for reclamation and rehabilitation, share capital and income taxes. Critical judgments and estimates in applying policies that have the most significant effect on the amounts recognized in the consolidated financial statements include the following: Determination of ore reserves and resources Judgments about the amount of product that can be economically and legally extracted from the Company's properties are made by management using a range of geological, technical and economic factors, history of conversion of mineral deposits to proven and probable reserves as well as data regarding quantities, grades, production techniques, recovery rates, production costs, commodity prices and exchange rates. This process may require complex and difficult geological judgments to interpret the data. The Company uses qualified persons (as defined by the Canadian Securities Administrator's National Instrument 43-101) to compile this data. Changes in the judgments surrounding reserves and resources may impact the carrying value of mineral properties, plant and equipment (Note 10), reclamation and rehabilitation provisions (Note 14), recognition of deferred income tax amounts (Note 23), and depreciation, depletion and amortization (Note 8,9,10). Estimating the quantity and /or grade of reserves and resources requires the size, shape and depth of ore bodies or fields to be determined by analyzing geological data such as drilling samples. Following this, the quantity of ore that can be extracted in an economical manner is calculated using data regarding the life of mine plans and forecast sales prices (based on current and long-term historical average price trends). Changes in estimates can be the result of estimated future production differing from previous forecasts of future production, expansion of mineable ore through exploration activities, differences between estimated and actual costs of mining and differences in the commodity price used in the estimation of mineable ore. Review of asset carrying values and assessment of impairment (accounting policy Note 3h) Management applies significant judgment in assessing each cash-generating unit and assets for the existence of indicators of impairment or impairment reversal at the reporting date. Internal and external factors are considered in assessing whether indicators are present that would necessitate impairment testing. Significant assumptions regarding commodity prices, operating costs, capital expenditures and discount rates are used in determining whether there are any indicators of impairment. These assumptions are reviewed regularly by senior management and compared, when applicable, to relevant market consensus views. If an indicator of impairment ore reversal exists, the asset's recoverable amount is estimated. The recoverable amount is the greater of fair value less costs of disposal and value in use. The determination of fair value less costs of disposal and value in use requires management to make estimates and assumptions about expected production and sales volumes, metal prices, ore tonnage and grades, recoveries, operating costs, future capital expenditures and appropriate discount rate for future cash flows. The estimates and assumptions are subject to risk and uncertainty, and as such there is the possibility that changes in circumstances will alter these projections, which may impact the recoverable amount of the assets. In such circumstances, some or all of the carrying value of the assets may be further impaired or the impairment charge reduced with the impact recorded in profit or loss. Achievement of commercial production (accounting policy Note 3g). Once a mine reaches the operating levels intended by management, depreciation of capitalized costs begins. Significant judgment is required to determine when certain of the Company's assets reach this level. Management considers several factors including: completion of a reasonable period of commissioning; consistent operating results achieved at a pre-determined level of design capacity and indications exist that this level will continue; mineral recoveries at or near expected levels; and the transfer of operations from development personnel to operational personnel has been completed. Estimation of the amount and timing of reclamation and rehabilitation costs (accounting policy Note 3j) Accounting for restoration requires management to make estimates of the future costs the Company will incur to complete the reclamation and rehabilitation work required to comply with existing laws, regulations and agreements in place at each mining operation and any environmental and social principles the Company is in compliance with. The calculation of the present value of these costs also includes assumptions regarding the timing of reclamation and rehabilitation work, applicable risk-free interest rate for discounting those future cash flows, inflation and foreign exchange rates and assumptions relating to probabilities of alternative estimates of future cash flows. Actual costs incurred may differ from those amounts estimated. Also, future changes to environmental laws and regulations could increase the extent of reclamation and rehabilitation work required to be performed by the Company. Increase in future costs could materially impact the amounts charged to operations for reclamation and rehabilitation. Taxes (Note 23) Judgment is required in determining the recognition and measurement of deferred income tax assets and liabilities on the balance sheet. In the normal course of business, the Company is subject to assessment by taxation authorities in various jurisdictions. These authorities may have different interpretations of tax legislation or tax agreements than those applied by the Company in computing current and deferred income taxes. These different interpretations may alter the timing or amounts of taxable income or deductions. Final taxes payable and receivable are dependent on many factors, including outcomes of tax litigation and resolution of disputes. The resolution of these uncertainties may result in adjustments to the Company's tax assets and liabilities. Management assesses the likelihood and timing of taxable earnings in future periods in recognizing deferred income tax assets. Estimates of future taxable income are based on forecasted cash flows using life of mine projections and the application of existing tax laws in each jurisdiction. To the extent that future cash flows and taxable income differ significantly from estimates, the ability of the Company to realize the net deferred income tax assets recorded at the balance sheet date could be impacted. In addition, future changes to tax laws could limit the ability of the Company to obtain tax deductions in future periods from deferred income tax assets. Deferred income tax assets are disclosed in Note 23. Inventory (Note 6) In valuing inventories at the lower of cost and net realizable value, the Company makes estimates in determining the net realizable price and in quantifying the contained metal in finished goods and work in progress.
Cash and cash equivalents [Policy Text Block]	(c) Cash and cash equivalents consist of deposits in banks and highly liquid investments with an original maturity at the date of the purchase of no more than ninety days, or that are readily convertible into cash.
Marketable securities [Policy Text Block]	(d) Marketable securities include investments in shares of companies and other investments capable of reasonably prompt liquidation. Share investments are measured at fair value through profit and loss and carried at fair value. Unrealized gains and losses are recognized in profit or loss.
Inventories [Policy Text Block]	(e) Work-in-process inventories, including ore stockpiles, are valued at the lower of production cost and net realizable value, after an allowance for further processing costs. Finished goods inventory, characterized as doré bars or concentrate, is valued at the lower of production cost and net realizable value. Materials and supplies are valued at the lower of cost and replacement cost. Similar inventories within the consolidated group are measured using the same method, and the reversal of previous write-downs to net realizable value is required when there is a subsequent increase in the value of inventories.
Intangible assets [Policy Text Block]	(f) Intangible assets are initially recognized at cost if acquired externally, or at fair value if acquired as part of a business combination and have a useful life of greater than one year. Intangible assets which have finite useful lives are measured at cost less accumulated amortization and accumulated impairment. Intangible assets that are assessed as having a finite useful life are amortized over their useful life on a straight-line basis from the date they become available for use and are tested for impairment if indications exist that they may be impaired. The useful life is determined using the period of the underlying contract or the period over which the intangible asset can be expected to be used.
Mineral properties, plant and equipment [Policy Text Block]	(g) Mineral properties, plant and equipment are stated at cost less accumulated depreciation, depletion and accumulated impairment losses. The cost of mineral properties, plant and equipment items consists of the purchase price, any costs directly attributable to bringing the asset to the location and condition necessary for its intended use and an initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located. Mineral properties include direct costs of acquiring properties (including option payments) and costs incurred directly in the development of properties once the technical feasibility and commercial viability has been established. Development costs relating to specific properties are capitalized once management determines a property will be developed. A development decision is made based upon consideration of project economics, including future metal prices, reserves and resources, and estimated operating and capital costs. Capitalization of costs incurred, and proceeds received from the sale of goods produced during the testing phase ceases when the property is capable of operating at levels intended by management. Exploration and evaluation costs are those costs required to acquire a mineral property and determine commercial feasibility. These costs include costs to establish an initial mineral resource and determine whether inferred mineral resources can be upgraded to measured and indicated mineral resources and whether measured and indicated mineral resources can be converted to proven and probable reserves. The Company recognizes acquisition costs for exploration and evaluation properties as assets when acquired as part of a business combination or asset purchase. All other exploration and evaluation costs are expensed as incurred until the technical feasibility and commercial viability of the property has been established and a development decision has been made. Capitalized exploration and evaluation costs for a project are classified as such until the project demonstrates technical feasibility and commercial viability. Upon demonstrating technical feasibility and commercial viability, and subject to an impairment analysis, capitalized exploration and evaluation costs are transferred to mineral property costs within mineral properties, plant and equipment. Technical feasibility and commercial viability generally coincide with the establishment of proven and probable reserves; however, this determination may be impacted by management's assessment of certain modifying factors. Where an item of plant and equipment comprises major components with different useful lives, the components are accounted for as separate items of plant and equipment and amortized separately over their useful lives. Plant and equipment are recorded at cost and amortized using either the straight-line method at rates varying from 5% to 30% annually or amortized on a units of production method, based on proven and probable reserves. The accumulated costs of mineral properties that are developed to the stage of commercial production are amortized using the units of production method, based on proven and probable reserves (as defined by National Instrument 43-101). The Company conducts an annual assessment of the residual balances, useful lives and depreciation methods being used for mineral properties, plant and equipment and any changes arising from the assessment are applied by the Company prospectively.
Impairment of Non-Current Assets [Policy Text Block]	(h) The Company's tangible assets are reviewed for indications of impairment or reversal of a previous impairment at each financial statement date. If an indicator of impairment or reversal exists, the asset's recoverable amount is estimated. An impairment loss is recognized when the carrying amount of an asset, or its cash-generating unit, exceeds its recoverable amount. A cash-generating unit is the smallest identifiable group of assets that generates cash flows that are largely independent of the cash flows from other assets or groups of assets. Impairment losses are recognized in profit and loss for the period. The recoverable amount is the greater of fair value less costs of disposal and value in use. In assessing value in use, the 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. For an asset that does not generate largely independent cash inflows, the recoverable amount is determined for the cash-generating unit to which the asset belongs. An impairment loss is reversed if there is an indication that there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset's carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized. Management periodically reviews the carrying values of its exploration and evaluation assets with internal and external mining related professionals. A decision to abandon, reduce or expand a specific project is based upon many factors including general and specific assessments of reserves, forecast future metal prices, forecast future costs of exploring, developing and operating a producing mine, expiration term and ongoing expense of maintaining leased mineral properties and the general likelihood that the Company will continue exploration. The Company does not set a pre-determined holding period for properties with unproven reserves. However, properties which have not demonstrated suitable mineral concentrations at the conclusion of each phase of an exploration program are re-evaluated to determine if future exploration is warranted and their carrying values are recoverable. If any area of interest is abandoned or it is determined that its carrying value cannot be supported by future production or sale, the related costs are recognized in profit or loss in the period of abandonment or determination that the carrying value exceeds its fair value. The amounts recorded as mineral properties represent costs incurred to date and do not necessarily reflect present or future values.
Leases [Policy Text Block]	(i) Effective January 1, 2019, at inception of a contract, the Company assesses whether a contract is or contains a lease. A contract is or contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Company recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of use asset is initially measured at cost, which is composed of: The amount of the initial measurement of the lease liability Any lease payments made at or before the commencement date Any indirect costs incurred An estimate of costs to dismantle and remove the underlying asset or to restore the site on which the asset is located Less any incentives received from the lessor The right-of-use asset is depreciated using the straight-line method from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term. Estimated useful lives of right-of-use assets are determined on the same basis as those of property and equipment. The lease liability 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. Lease payments included in the measurement of the lease liability are composed of: Fixed payments, including in-substance fixed payments Variable lease payments that depend on an index or rate, initially measured using the index or rate as at the commencement date Amounts expected to be payable under a residual value guarantee; and The exercise price under a purchase option that the Company is reasonably certain to exercise, lease payments in an optional renewal period if the Company is reasonably certain to exercise an extension option, and penalties for early termination of a lease unless the Company is reasonably certain not to terminate early. The lease payments exclude variable payments which are dependent on external factors other than an index or a rate. These variable payments are recognized directly in profit or loss. The lease liability is remeasured when there is a change in future lease payments arising from a change in an index or rate, if there is a change in the Company's estimated amount expected to be 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 liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use asset or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero. The Company has elected not to recognize right-of-use assets and lease liabilities for short-term leases that have a lease term of 12 months or less and leases of low-value assets. The lease payments associated with these leases are expensed on a straight-line basis over the lease term.
Provision for Reclamation and Rehabilitation [Policy Text Block]	(j) The Company recognizes provisions for statutory, contractual, constructive or legal obligations associated with the decommissioning and reclamation of mineral properties, plant and equipment, when those obligations result from the acquisition, construction, development or normal operation of the assets. A liability is recognized at the time environmental disturbance occurs and the resulting costs are capitalized to the corresponding asset. The provision for reclamation and rehabilitation obligations is estimated using expected cash flows based on engineering and environmental reports prepared by third-party industry specialists and is discounted at a pre-tax rate specific to the liability. The capitalized amount is amortized on the same basis as the related asset. In subsequent periods, the liability is adjusted for any changes in the amount or timing of the estimated future cash costs, changes in the discount or inflation rates and for the accretion of discounted underlying future cash flows. The unwinding of the effect of discounting the provision is recorded as a finance cost in profit or loss for the period.
Revenue recognition [Policy Text Block]	(k) Revenue is generated from the sale of refined silver and gold or from the sale of these metals contained in doré or concentrate. Revenue for doré is recorded in the consolidated statement of comprehensive income gross of treatment and refining costs paid to counterparties under the terms of the sales agreements. Revenue for concentrate is recorded in the consolidated statement of comprehensive income net of treatment and refining costs paid to counterparties under the terms of the sales agreements. Revenue is recognized when control of the metal is transferred to the customer in an amount that reflects the consideration the Company expects to receive in exchange for the metals. In determining whether the Company has satisfied its performance obligation, it considers the indicators of the transfer of control, which include but are not limited to, whether: the Company has a present right to payment; the customer has a legal title to the asset; the Company has transferred physical possession of the asset to the customer; and the customer controls the risks and rewards of ownership of the asset. Revenue from metals in doré The refiners who receive doré from the Company refine the materials on the Company's behalf. The refiners transfer the refined product to our customers according to the Company's instructions. Refined metals are sold at spot prices with sales proceeds collected upon or within several days of the completion of the sales transaction. Revenue from sale of doré is recognized at the time a metal sale is executed and the Company has irrevocably directed the refiner to deliver the refined metal to the customer. Revenue from metals in concentrate Metals in concentrate are sold under pricing arrangements where final prices are determined by market prices subsequent to the date of sale. Revenue from the sale of concentrates is provisionally priced at the date control transfers. On transfer, the Company recognizes revenue on a provisional basis based on current prices and at each period end, re-estimated prices based on forward market prices for the estimated month of settlement. The final selling price is subject to movements in metal prices up to the final settlement date. Revenue is initially recognized based on the estimated mineral content then adjusted to final settlement adjustments. Final settlement periods range from two to six months after delivery of the product. Variations between the sales price recorded at the initial recognition date and the actual final sales price at the settlement date, caused by changes in market metal prices, results in an embedded derivative in the related trade accounts receivable. For each reporting period until final settlement, forward market prices are used to record revenue. The embedded derivative is recorded at fair value each period until final settlement occurs, with changes in fair value classified as an adjustment to revenue.
Share-based payments [Policy Text Block]	(l) The Company has a share option plan and performance share unit plan which are described in Note 15(c) and Note 15(d) respectively. Equity-settled share-based payment awards to employees are measured by reference to the fair value of the equity instruments granted and are charged over the vesting period using the graded vesting method. The amount recognized as an expense is adjusted to reflect the actual number of share options for which the related service and vesting conditions are met. Equity-settled share-based payment awards to non-employees are measured at the fair value of the goods or services received as the goods or services are received, unless that fair value cannot be measured reliably, in which case they are measured by reference to the fair value of the equity instrument. The offset is credited to contributed surplus. Consideration received on the exercise of stock options is recorded as share capital and the related contributed surplus is transferred to share capital. For those options that expire or are forfeited after vesting, the amount previously recorded in contributed surplus is transferred to deficit. Share-based compensation expense relating to cash-settled awards, including deferred share units and share appreciation rights which are described in Note 15(e) and Note 15(f), is recognized over the vesting period of the units based on the fair market value of the units. As these awards will be settled in cash, the expense and liability are adjusted each reporting period for changes in the fair value.
Income taxes [Policy Text Block]	(m) Income tax expense (recovery) comprises current and deferred tax. It is recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or other comprehensive income. Current tax comprises the expected tax payable or receivable on the taxable income or loss for the year and any adjustments to the tax payable or receivable in respect of previous years. The amount of current tax payable or receivable is the is the best estimate of the tax amount expected to be paid or received that reflects uncertainty relate to income taxes, if any. It is measured using tax rates enacted or substantively enacted at the reporting date. Current tax also includes any tax arising from dividends. The Company follows the asset and liability method of accounting for deferred income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and tax losses carried forward. Deferred tax assets and liabilities are measured using substantively enacted or enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in profit or loss in the period that includes the substantive enactment date. Deferred tax assets are recognized to the extent their recovery is considered probable based on their term to expiry and estimates of future taxable income. 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; such reductions are reversed when the probability of future taxable profits improve.
Earnings per share [Policy Text Block]	(n) Basic earnings per share is computed by dividing the net earnings (loss) available to common shareholders by the weighted average number of shares
Business combinations [Policy Text Block]	(o) On a business combination, the acquisition method of accounting is used, whereby the purchase consideration is allocated to the identifiable assets, liabilities and contingent liabilities (identifiable net assets) based on fair value at the date of acquisition. When the cost of acquisition exceeds the fair values attributable to the Company's share of identifiable net assets, the difference is treated as purchased goodwill. If the fair value attributable to the Company's share of the identifiable net assets exceeds the cost of acquisition, the difference is immediately recognized in the profit or loss. Incremental costs related to acquisitions are expensed as incurred. Determination of the fair value of assets acquired and liabilities assumed and resulting goodwill, if any, requires that management make estimates based on the information provided by the acquiree. Changes to the provisional values of assets acquired and liabilities assumed, deferred income taxes and resulting goodwill, if any, will be adjusted when the final measurements are determined (within one year of the acquisition date). When purchase consideration is contingent on future events, the initial cost of the acquisition recorded includes an estimate of the fair value of the contingent amounts expected to be payable in the future. Changes to the estimated fair value of contingent consideration subsequent to the acquisition date are recorded in profit or loss.
Financial Instruments [Policy Text Block]	(p) The Company recognizes financial assets and financial liabilities on the date the Company becomes party to the contractual provisions of the instruments. On initial recognition, all financial assets and financial liabilities are recorded at fair value, net of attributable transaction costs, except for financial assets and liabilities classified as fair value through profit and loss ("FVTPL"). Transaction costs of financial assets and liabilities classified as FVTPL are expensed in the period in which they are incurred. A financial asset is derecognized either when the Company has transferred substantially all the risks and rewards of ownership of the financial assets or when cash flows expire. A financial liability is derecognized when the obligation specified in the contract is discharged, cancelled or expired. On initial recognition, the Company classifies and measures financial assets as either fair value through profit and loss ("FVTPL"), fair value through other comprehensive income ("FVTOCI") or amortized cost. Subsequent measurement of financial assets depends on the classifications of such assets. The basis of classification depends on an entity's business model and the contractual cash flows of the financial asset. Amortized cost Financial assets that meet the following conditions are measured subsequently at amortized cost: The financial asset is held within a business model whose objective is to hold financial assets in order to collect contractual cash flows, and The contractual terms of the financial asset provide cash flows on specified dates that are solely payments of principal and interest on the principal amount outstanding The amortized cost of a financial asset is the amount at which the financial asset is measured at initial recognition minus the principal repayments, plus the cumulative amortization using the effective interest method of any difference between the initial amount and the maturity amount, adjusted for any loss allowance. Interest income is recognized using the effective interest method. Fair value through other comprehensive income Financial assets that meet the following conditions are measured subsequently at amortized cost: The financial asset is held within a business model whose objective is achieved by both collecting the contractual cash flows and selling financial assets, and The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding Investments in equity instruments at FVTOCI are initially recognized at fair value. Subsequently, they are measured at fair value, with gains and losses arising from changes from initial recognition recognized in OCI. Designation at FVTOCI is not permitted if the equity investment is held for trading or if it is contingent consideration recognized by an acquirer in a business combination. Fair value through profit and loss By default, all other financial assets are measured at FVTPL. The Company, at initial recognition, may also irrevocably designate a financial asset as measured at FVTPL if doing so eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise from measuring assets or liabilities or recognizing the gains or losses on them on a different basis. Financial assets measured at FVTPL are measured at fair value at the end of each reporting period, with any fair value gains or losses recognized in profit or loss to the extent that they are not part of a designated hedging relationship. Determination of fair value is further described in Note 24. Financial liabilities and equity Debt and equity instruments are classified as either financial liabilities or as equity in accordance with the substance of the contractual arrangement and the definitions of a financial liability and an equity instrument. An equity instrument is any contract that evidences a residual interest in the assets of the Company after deducting all its liabilities. Equity instruments issued by the Company are measured at the proceeds received, net of direct issue costs. Financial liabilities that are not contingent consideration of an acquirer in a business combination, held for trading or designated as FVTPL, are measured at amortized cost using the effective interest method. The Company's financial instruments are recognized as: Assets Cash and cash equivalents Amortized cost Trade and other receivables (other than derivatives) Amortized cost Trade receivables (derivative component) FVTPL Other investments FVTPL Liabilities Accounts payable and accrued liabilities Amortized cost Loans payable Amortized cost Performance share units and Deferred share units FVTPL
Accounting standards adopted during the year [Policy Text Block]	(q) On May 14, 2020, the International Accounting Standard Board (IASB) published a narrow scope amendment to IAS 16 Property, Plant and Equipment - Proceeds before Intended Use. The amendment prohibits deducting from the cost of property, plant and equipment amounts received from selling items produced while preparing the asset for its intended use. Instead, amounts received will be recognized as sales proceeds and the related costs in profit or loss. The effective date is for annual periods beginning on or after January 1, 2022. The Company is assessing the effect of the narrow scope amendment on its consolidated financial statements. On August 27, 2020, the IASB published "Interest Rate Benchmark Reform - Phase 2" 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 periods beginning on or after January 1, 2021, with earlier application permitted. The Company does not anticipate that the adoption will have a material impact on its consolidated financial statements as the Company is not engaged in hedging activities and as at December 31, 2021 only had $2.0 million in equipment loans whose terms will require a replacement with an alternative benchmark rate.
