Significant Accounting Policies [Abstract]
Significant accounting policies [Text Block]	3. Significant accounting policies The accounts policies described in this section were those applied by the Company and/or the JV (see note 8) during the year ended December 31, 2021 and 2020. (a) The Company conducts a portion of its business through joint arrangements where the parties are bound by contractual arrangements establishing joint control and decisions about the activities that significantly affect the returns of the investee require unanimous consent. A joint arrangement is classified as either a joint operation or a joint venture, subject to the terms that govern each investor's rights and obligations in the arrangement. In a joint operation, the investor has rights and obligations to the separate assets and liabilities of the investee and in a joint venture, the investors have rights to the net assets of the joint arrangement. For a joint operation, the Company recognizes its share of the assets, liabilities, revenue, and expenses of the joint arrangement, while for a joint venture, the Company accounts for its investment in the joint arrangement using the equity method. Under the equity method, the Company's investment in a joint venture is initially recognized at cost and subsequently increased or decreased to recognize the Company's share of net earnings or losses of the joint venture, after any adjustments necessary for impairment losses after the initial recognition date. The total carrying amount of the Company's investment in a joint venture also includes any long-term debt interests which in substance form part of the Company's net investment. The Company's share of a joint venture's losses that are in excess of its investment are recognized only to the extent that the Company has incurred legal or constructive obligations or made payments on behalf of the joint venture. The Company's share of net earnings or losses of a joint venture are recognized in net earnings during the period. Dividends and repayment of capital received from a joint venture are accounted for as a reduction in the carrying amount of the Company's investment. Balances between the Company and its joint ventures are not eliminated. At the end of each reporting period, the Company assesses whether there is any objective evidence that an investment in a joint venture is impaired. Objective evidence includes observable data indicating there is a measurable decrease in the estimated future cash flows of the joint venture's operations. When there is objective evidence that an investment is impaired, the carrying amount of such investment is compared to its recoverable amount, being the higher of its fair value less costs of disposal and value-in-use. If the recoverable amount of an investment is less than the carrying amount, the carrying amount is reduced to its recoverable amount and a corresponding impairment loss is recognized in the period in which the relevant circumstances are identified. When an impairment loss reverses in a subsequent period, the carrying amount of the investment is increased to the revised estimate of the recoverable amount to the extent that the increased carrying amount does not exceed the carrying amount that would have been determined had an impairment loss not been previously recognized. A reversal of an impairment loss is recognized in net earnings in the period in which the reversal occurs. Similar to the assessment of impairment for subsidiaries, the Company reviews the mining properties and plant and equipment for a joint arrangement at the cash-generating unit level to determine whether there is any indication that these assets are impaired. (b) Transactions in foreign currencies are initially recorded at the functional currency rate of exchange at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated at the functional currency rate of exchange at the date of the statement of financial position. Foreign exchange gains (losses) are recorded in the consolidated statement of operations and comprehensive income (loss) for the year. Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates as at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value is determined. (c) Cash and cash equivalents consist of cash on hand and short-term investments with original maturity dates of less than ninety days or that are fully redeemable without penalty or loss of interest. (d) Gold on hand, gold in process and stockpiled ore inventories are recorded at the lower of weighted average production cost and net realizable value. Production costs include the cost of raw materials, direct labour, mine-site overhead expenses and applicable depreciation and depletion. Net realizable value is calculated as the estimated price at the time of sale based on prevailing and long-term metal prices less estimated future costs to convert the inventories from their respective states into saleable form less estimated costs to sell. Production costs are included in work-in-process inventory based on current costs incurred up to the point of dore production. The costs of finished goods represent the costs of work-in-process inventories plus applicable treatment costs. The costs of inventories sold during the period are presented as production costs in the statement of operations and comprehensive income (loss) for the period. Additions to the cost of ore stockpiles are based on the related current cost of production for the period, while reductions in the cost of ore stockpiles are based on the weighted-average cost per tonne of ore in the stockpile. Stockpiles are segregated between current and non-current inventories in the consolidated statement of financial position based on the planned period of usage. Supplies and spare parts are valued at the lower of weighted-average cost and net realizable value. Replacement costs of materials and spare parts are generally used as the best estimate of net realizable value. Provisions are recorded to reduce the carrying amount of materials and spare parts inventory to net realizable value to reflect current intentions for the use of redundant or slow-moving items. Provisions for redundant and slow-moving items are made by reference to specific items of inventory. The Company reverses write-downs where there is a subsequent increase in net realizable value and where the inventory is still on hand. (e) (i) Recognition Capitalized costs of mining properties include the following: - - - - - - Stripping costs In open pit mining operations, it is necessary to incur costs to remove overburden and other mine waste materials in order to access the ore from which minerals can be extracted economically. Stripping costs incurred in order to provide initial access to the ore body (referred to as pre-production stripping) are capitalized as incurred. Stripping costs incurred during the production stage of an open pit mine are accounted for as production costs in the consolidated statement of operations and comprehensive income during the period that the stripping costs were incurred, unless these costs provide a future economic benefit. Production phase stripping costs are considered to generate a future economic benefit when (i) it is probable that future economic benefit associated with the stripping activity will flow to the entity; (ii) the entity can identify the component of the ore body for which access has been improved; and (iii) the costs relating to the stripping activity associated with that component can be measured reliably. These costs are capitalized as mineral properties, plant and equipment. Production costs are allocated between inventory produced and the stripping asset based on the volume of waste extracted compared with the expected volume, for a given volume of ore production. Stripping costs incurred and capitalized during the production phase are depleted using the units-of-production method over the proven and probable reserves (ore tonnes) of the component of the ore body to which access has been improved as a result of the specific stripping activity. Management reviews the estimates of the waste and ore in each identified component of operating open pit mines at the end of each financial year, and when events and circumstances indicate that such a review should be made. Deferred stripping assets are written-down to their recoverable amount when their carrying value is not considered supportable. Changes to the estimated identification of components and the associated waste and ore within each component are accounted for prospectively. Exploration and evaluation expenditures Exploration and evaluation expenditures include the costs of acquiring rights to explore, exploratory drilling and related exploration costs incurred on sites without an existing mine and on areas outside the boundary of a known mineral deposit which contain proven and probable reserves. Exploration and evaluation expenditures incurred on a mineral deposit, with the exception of acquisition costs and costs arising from the recognition of an asset retirement provision, are expensed as incurred up to the date of establishing that costs incurred on a mineral deposit are technically feasible and commercially viable. Expenditures incurred on a mineral deposit subsequent to the establishment of its technical feasibility and commercial viability are capitalized and included in the carrying amount of the related mining property. The technical feasibility and commercial viability of a mineral deposit is assessed based on a combination of factors, such as, but not limited to: - - - - Borrowing costs Borrowing costs directly relating to the financing of qualifying assets are added to the capitalized cost of those related assets until such time as the assets are substantially ready for their intended use or sale which, in the case of mining properties, is when they are capable of commercial production. Where funds have been borrowed specifically to finance a project, the amount capitalized represents the actual borrowing costs incurred. Where the funds used to finance a project form part of general borrowings, the amount capitalized is calculated using a weighted average of rates applicable to relevant general borrowings of the Company during the period. Capitalized borrowing costs are depreciated over the life of the related asset. All other borrowing costs are recognized in the consolidated statement of operations and comprehensive income in the year in which they are incurred. Borrowing costs are included as part of interest paid in the statement of cash flows. Depletion Mineral properties in production are depleted on a mine-by-mine basis using the units-of-production method over the mine's estimated proven and probable reserves, with the exception of deferred stripping which is depleted using the unit-of-production method over the reserves that directly benefit from the specific stripping activity and will commence when the mine is capable of operating in the manner intended by management. In the event proven and probable reserves are not identified management will use their best estimate from internally generated information. The Company uses a number of criteria to assess whether the mine is in the condition necessary for it to be capable of operating in a manner intended by management. These criteria include, but are not limited to: - - - - - Mineral properties in development are not depleted. (ii) Recognition The cost of plant and equipment consists of the purchase price, costs directly attributable to the delivery of the asset to the location and the condition necessary for it to be capable of operating in the manner intended by management, including the cost of testing whether these assets are operating in the manner intended by management. Subsequent costs are included in the asset's carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Company and the cost can be measured reliably. Where significant components of an asset have differing useful lives, depreciation is calculated on each separate component. Depreciation Depreciation of an asset begins when it is available for use, i.e. when it is in the location and condition necessary for it to be capable of operating in the manner intended by management. The carrying amounts of plant and equipment are depreciated using either the straight-line or units-of-production method over the shorter of the estimated useful life of the asset or the life of mine. The significant classes of depreciable plant and equipment and their estimated useful lives are as follows: Asset Class Estimated Useful Life Fixed plant & related components and infrastructure Units of production over life of mine Mobile and other mine equipment components 3 to 12 years Computer equipment and software 3 years Right-of-use assets Straight-line over lease term Management reviews the estimated useful lives, residual values and depreciation methods of the Company's plant and equipment at the end of each financial year, and when events and circumstances indicate that such a review should be made. Changes to estimated useful lives, residual values or depreciation methods resulting from such review are accounted for prospectively. Major maintenance and repairs Expenditure on major maintenance and repairs includes the cost of replacement parts of assets and overhaul costs. Where an asset or part of an asset is replaced and it is probable that future economic benefits associated with the item will be available to the Company, that expenditure is capitalized and the carrying amount of the item replaced derecognized. Similarly, overhaul costs associated with major maintenance are capitalized when it is probable that future economic benefits will be available and any remaining carrying amounts of the cost of previous overhauls are derecognized. All other maintenance and repair costs are expensed as incurred. (iii) The carrying amounts of assets included in mineral properties, plant and equipment are reviewed for impairment when events and changes in circumstances indicate that the related carrying amounts may not be recoverable. If any such indication exists, the recoverable amount of the relevant cash-generating unit ("CGU") is estimated in order to determine the extent of impairment. A CGU is the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. The carrying amounts of the CGUs are compared to their recoverable amounts where the recoverable amount is the higher of value-in-use ("VIU") and fair value less costs to sell ("FVLCS"). FVLCS is defined as the amount that would be obtained from the sale of the asset in an orderly transaction between market participants at the measurement date. VIU is determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset in its present form and from its ultimate disposal. The fair value of mine sites is generally determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset, including any expansion prospects. If a reliable estimate of future cash flows cannot be made, then fair value is determined by reference to market prices for comparable assets. If the recoverable amount of an asset (or CGU) is estimated to be less than its carrying amount, the carrying amount is reduced to its recoverable amount. An impairment is recognized immediately in the consolidated statement of operations and comprehensive income. Mineral properties, plant and equipment that have been impaired are tested for possible reversal of the impairment whenever events or changes in circumstances indicate that the impairment may have reversed. When an impairment loss reverses in a subsequent period, the revised carrying amount shall not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset previously, less subsequent depletion and depreciation. Reversals of impairment losses are recognized in the consolidated statements of operations in the period in which the reversals occur. (iv) Upon disposal or abandonment, the carrying amounts of mineral properties and plant and equipment are derecognized and any associated gains or losses are recognized in the consolidated statement of operations and comprehensive income. (f) 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. To assess whether a contract conveys the right to control the use of an identified asset, the Company assesses whether it has the right to obtain substantially all of the economic benefits from and to direct the use of the identified asset. At commencement or on modification of a contract that contains a lease component, the Company allocates the consideration in the contract to each lease component on the basis of its relative stand-alone prices. 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 comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset, or the site on which it is located, less any lease incentives received. The right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the end of the lease term, unless the lease transfers ownership of the underlying asset to the Company by the end of the lease term or the cost of the right-of-use asset reflects that the Company will exercise a purchase option. In that case, the right-of-use asset will be depreciated over the useful life of the underlying asset, which is determined on the same basis as those of property and equipment. In addition, the right-of-use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability. 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. Generally, the Company uses its incremental borrowing rate as the discount rate. The Company determines its incremental borrowing rate by obtaining interest rates from various external financing sources and makes certain adjustments to reflect the terms of the lease and type of the asset leased. Lease payments included in the measurement of the lease liability comprise the following: • fixed payments, including in-substance fixed payments; • variable lease payments that depend on an index or a 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 liability is measured at amortized cost using the effective interest method. It 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 estimate of the amount expected to be payable under a residual value guarantee, if the Company changes its assessment of whether it will exercise a purchase, extension or termination option, or if there is a revised in-substance fixed lease payment. 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 the consolidated statement of operations and comprehensive income if the carrying amount of the right-of-use asset has been reduced to zero. Short-term leases and leases of low-value assets The Company has elected not to recognize right-of-use assets and lease liabilities for leases of low-value assets and short-term leases, including office equipment. The Company recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term. (g) General Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. Where the Company expects some or all of a provision to be reimbursed, for example under an insurance contract, the reimbursement is recognized as a separate asset, but only when the reimbursement is virtually certain. The expense relating to any provision is presented in the consolidated statement of operations and comprehensive income net of any reimbursement. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects where appropriate, the risks specific to the liability. Where discounting is used, the increase in the provision due to the passage of time is recognized as finance expense in the consolidated statement of operations and comprehensive income. Asset retirement provisions An obligation to incur restoration, rehabilitation and environmental costs arises when environmental disturbance is caused by the exploration, development or ongoing production of a mineral property interest. The Company records the estimated present value of future cash flows associated with site reclamation as a liability when the liability is incurred with a corresponding increase in the carrying value of the related assets. Discount rates using a pre-tax, risk-free rate that reflect the time value of money are used to calculate the net present value. The liability is accreted over time to reflect the unwinding of the discount with the accretion expense included in finance costs in the consolidated statement of operations and comprehensive income (loss). Changes in estimates or circumstances include changes in legal or regulatory requirements, increased obligations arising from additional mining and exploration activities, changes to cost estimates, changes to the discount rate and changes to the risk-free interest rates. (h) Revenue is derived from the sale of gold and by-products. Revenue is recognized for contracts with customers when there is persuasive evidence that all of the following criteria are met: - - - - - Revenue from gold and any by-product metals is generally recorded at the time of physical delivery of the refined gold, which is also the date when control of the gold passes to the customer. Revenue from saleable gold produced during the testing phase of production activities, and the cost of producing those items, is recognized in profit or loss. (i) Royalty payments to governments which are based on gross revenue are not considered income taxes and are recognized as an expense in the statement of operations and comprehensive income (loss). (j) (i) Recognition and measurement The Company recognizes a financial asset in its statement of financial position when the Company becomes party to the contractual provisions of the instrument. All financial assets are initially recorded at fair value plus directly attributable transaction costs and classified as either (i) financial assets subsequently measured at amortized cost, (ii) financial assets subsequently measured at fair value through other comprehensive income or (iii) financial assets subsequently measured at fair value through profit or loss. The basis of classification takes into consideration both the Company's business model for managing and the contractual cash flow characteristics of the financial assets. A financial asset is measured at amortized cost if 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 give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. A financial asset is measured at fair value through other comprehensive income if the financial asset is held within a business model whose objective is achieved by both collecting 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. A financial asset is measured at fair value through profit or loss unless it is measured at amortised cost or at fair value through other comprehensive income. Fair value changes in financial assets classified as fair value through profit or loss, if any, are recognized in the consolidated statement of operations and comprehensive income. Derecognition A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is derecognized when: - - (ii) Recognition and measurement All financial liabilities are initially recorded at fair value less transaction costs. All financial liabilities are subsequently measured at amortized cost using the effective interest method, except for: - - - - - Business combinations An entity may, at initial recognition, irrevocably designate a financial liability as measured at fair value through profit or loss when a contract contains one or more embedded derivatives, or when doing so results in more relevant information, because either (a) it eliminates or significantly reduces a measurement or recognition inconsistency (i.e. an accounting mismatch); or (b) a group of financial liabilities or financial assets and financial liabilities is managed and its performance is evaluated on a fair value basis. Fair value changes of financial liabilities classified as fair value through profit or loss, if any, are recognized in the consolidated statement of operations and comprehensive income. (k) The Company has a share option plan and share unit plan which are described in note 11. For share options, the fair value of share-based compensation awards is determined at the date of grant using the Black-Scholes option pricing model. The Company records all share-based compensation for options using the fair value method with graded vesting. Under the fair value method, share-based payments are measured at the fair value of the consideration received or the fair value of the equity instruments issued or liabilities incurred, whichever is more reliably measurable, and are charged over the vesting period to the consolidated statement of operations and comprehensive income. The offset is credited to Equity reserves ratably over the vesting period, after adjusting for the number of awards that are expected to vest. Expenses recognized for forfeited awards are reversed. For awards that are cancelled, any expense not yet recognized is recognized immediately in the statement of operations and comprehensive income. Where the terms of an equity-settled award are modified, as a minimum an expense is recognized as if the terms had not been modified over the original vesting period. In addition, an expense is recognized for any modification which increases the total fair value of the share-based payment arrangement as measured at the date of modification, over the remainder of the vesting period. For cash-settled share-based payments (note 11), the Company measures the goods or services acquired and the liability incurred at the fair value of the liability. The corresponding share-based compensation expense is recognized over the vesting period of the award. As these awards will be settled in cash, the liability is remeasured at fair value at each reporting period and at the date of settlement, with changes in fair value recognized in the consolidated statement of operations and comprehensive income in the period incurred. (l) Income tax on the profit or loss for the periods presented comprises current and deferred income tax. Income tax is recognized in the consolidated statement of operations and comprehensive income except to the extent that it relates to items recognized directly in equity, in which case it is recognized in equity. Current income tax expense is the expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted at period end, adjusted for amendments to tax payable with regards to previous years. Deferred income tax is recognized in respect of unused tax losses, tax credits and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, based on the tax rates that have been substantively enacted at the reporting date. A deferred income tax asset is recognized only to the extent that it is probable that future taxable profits will be available against which the asset can be utilized. To the extent that the Company does not consider it probable that a future income tax asset will be recovered, it does not recognize the asset. Deferred income tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the Company intends to settle its tax assets and liabilities on a net basis. The Company records foreign exchange gains and losses representing the impacts of movements in foreign exchange rates on the tax bases of non-monetary assets and liabilities which are denominated in foreign currencies. Foreign exchange gains and losses relating to the translation of the deferred income tax balance from local statutory accounts to functional currency accounts are included in deferred income tax expense or recovery in the consolidated statement of operations and comprehensive income. (m) Basic income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. The computation of diluted income per share assumes the conversion, exercise or contingent issuance of securities only when such conversion, exercise or issuance would have a dilutive effect on income per share. For this purpose, the treasury stock method is used for the assumed proceeds upon the exercise of stock options that are used to purchase common shares at the average market price during the period.

Changes in accounting standards [Text Block]	4. Changes in accounting standards (a) There were no new standards effective January 1, 2021 that impacted the Company's consolidated financial statements. (b) The following standards and interpretations, which may be applicable to the Company or the JV, have been issued but are not yet effective as of December 31, 2021: Amendment to IAS 16 On May 14, 2020, the IASB amended IAS 16 "Property, Plant and Equipment" to prohibit deducting from the cost of an item of property, plant and equipment any proceeds from selling items produced while bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Instead, an entity recognizes the proceeds from selling such items, and the cost of producing those items, in profit or loss. The amendments are effective for annual periods beginning on or after January 1, 2022 with early adoption permitted. The amendments to IAS 16 will not have a significant impact on the Company's or the JV's accounting policies.

Disclosure of changes in accounting estimates [abstract]
Significant accounting judgements and estimates [Text Block]	5. Significant accounting judgements and estimates The preparation of financial statements in conformity with IFRS requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Management believes the estimates and assumptions used in these consolidated financial statements are reasonable, however, actual results could differ from those estimates and could impact future results of operations and cash flows. The Company considered the impact of the COVID-19 pandemic on the significant judgments and estimates made in these consolidated annual financial statements and determined that the effects of COVID-19 did not have a material impact on the estimates and judgments applied. The accounting judgements and estimates which have the most significant effect on these financial statements and the financial results of the JV are as follows: Judgements Impairment indicators of equity investment in joint venture and MPP&E The Company considers both external and internal sources of information in assessing whether there are any indications that its equity investment in the JV and/or MPP&E are impaired. External sources of information the Company considers include changes in the market, economic and legal environment in which the JV operates that are not within its control and affect the recoverable amount of the Company's equity investment. Internal sources of information the Company considers include the manner in which mineral properties and plant and equipment of the JV are being used or are expected to be used and indications of economic performance of the assets. The judgements are subject to risk and uncertainty; hence, there is the possibility that changes in circumstances will alter these assumptions, which may impact the recoverable amount of the assets. In such circumstances, the carrying value of the Company's equity investment in the JV may be impaired or a prior period's impairment charge reversed with the impact recorded in the consolidated statement of operations and comprehensive income. Estimates Impairment assessments of the equity investment in the JV and MPP&E When facts and circumstances suggest the carrying value of the Company's equity investment in the JV or MPP&E may be impaired, the Company is required to estimate the recoverable amount through a FVLCS or VIU approach. Estimating the recoverable amount requires management to make significant estimates about the future life of mine cash flows of the AGM which may include, but may not be limited to, changes to the current estimates of in-situ ounces, ore tonnes to be mined in future periods, strip ratios, head grades, recovery rates, gold price assumptions, mining costs, processing costs, trucking costs, capital and closure costs, as well as discount rates. When assessing the recoverable amount of a CGU without defined mineral reserves, management may be required to make significant estimates about the fair value of in-situ mineral resources by reference to market rates for comparable assets. When facts and circumstances suggest the carrying value of the JV's mineral interests may be impaired, the same policies and set of assumptions as described above are applied. Mineral reserves Estimates of the quantities of proven and probable mineral reserves form the basis for the JV's life-of-mine plans, which are used for a number of key business and accounting purposes, including: the calculation of depletion expense, the capitalization of stripping costs, the forecasting and timing of cash flows related to the asset retirement provision and impairment assessments, if any. To the extent that these estimates of proven and probable mineral reserves vary, there could be changes in depletion expense, stripping assets, asset retirement provisions and impairment charges recorded. The Company determined it was not in a position to declare mineral reserves for the AGM in its updated National Instrument 43-101 Technical Report (“NI 43-101”), filed on March 29, 2022, with an effective date of February 28, 2022. This change in mineral reserve estimates will be applied prospectively. Depletion of plant and equipment Plant and equipment are depreciated to their estimated residual value over the estimated useful life of the asset. Should the actual useful life of the plant or equipment vary, future depreciation charges may change. Inventory valuation of production costs The JV estimates quantities of ore in stockpiles and in process and the recoverable gold contained in this material in order to determine the cost of inventories and the weighted average costs of finished goods sold during the period. To the extent that these estimates vary, production costs of finished goods may change. Net realizable value of inventory Estimates of net realizable value are based on the most reliable evidence available, at the time that the estimates are made, of the amount that the inventories are expected to realize. In order to determine the net realizable value of gold dore, gold-in-process and stockpiled ore, the JV estimates future metal selling prices, production forecasts, realized grades and recoveries, timing of processing, and future costs to convert the respective inventories into saleable form, if applicable. Reductions in metal price forecasts, increases in estimated future costs to convert, reductions in the number of recoverable ounces, and a delay in timing of processing can result in a write-down of the carrying amounts of the JV's stockpiled ore inventory. Materials and other supplies held for use in the production of inventories are not written down below cost if the finished products in which they will be incorporated are expected to be sold at or above cost. However, to the extent net realizable value of materials and spares must be estimated, replacement costs of the materials and spare parts are generally used as the best estimate of net realizable value. Current and deferred Income taxes In assessing the probability of realizing income tax assets recognized, management makes estimates related to expectations of future taxable income, applicable tax opportunities, expected timing of reversals of existing temporary differences and the likelihood that tax positions taken will be sustained upon examination by applicable tax authorities. Levels of future taxable income are affected by, among other things, market gold prices, production costs, quantities of proven and probable gold reserves, interest rates and foreign currency exchange rates. Where applicable tax laws and regulations are either unclear or subject to varying interpretations, it is possible that changes in these estimates could occur that materially affect the amounts of deferred income tax assets and liabilities recorded in the financial statements. Changes in deferred tax assets and liabilities generally have a direct impact on earnings in the period that the changes occur. Deferred stripping To determine whether stripping costs incurred during the production phase of a mining property relate to reserves and resources that will be mined in a future period and therefore should be capitalized, the JV makes estimates of the stripping activity over the life of the component of reserves and resources which have been made accessible. In addition, judgement is involved when allocating production costs between inventory produced and the stripping asset; the allocation is based on the volume of waste extracted compared with the expected volume, for a given volume of ore production. To the extent that these estimates and judgements change, there could be a change to the amount of production costs which are deferred to the statement of financial position. Asset retirement provisions Provisions for reclamation and closure cost obligations represents management's best estimate of the present value of the future cash outflows required to settle closure cost liabilities. Significant judgements and estimates are required in forming assumptions of future activities, future cash outflows and the timing of those cash outflows. These assumptions are formed based on environmental and regulatory requirements or the Company's environmental policies which may give rise to constructive obligations. The JV's assumptions are reviewed at the end of each reporting period and adjusted to reflect management's current best estimate and changes in any of the above factors can result in a change to the provision recognized by the JV. Changes to these estimates and judgements may result in actual expenditures in the future differing from the amounts currently provided for. Preferred shares The Company holds preferred shares (without a fixed redemption date) in the JV which have been classified as financial assets measured at fair value through profit or loss. As at December 31, 2021, management estimated the fair value of these preference shares by reference to a fair value of the AGM's in-situ mineral resources, plus the carrying value of stockpile inventories and other working capital balances. Several estimates were made to determine the fair value including, but not limited to, mineable resources, recoveries and a dollar per ounce market rate for in-situ mineral resources. Changes in one or more of these assumptions could lead to a materially different fair value estimate of the preferred shares. As at December 31, 2020, management estimated the fair value of these preference shares by discounting the forecast future cash flows from the AGM.

Disclosure Of Transactions Between Related Parties Abstract
Receivable due from related party [Text Block]	6. Receivable due from related party Under the terms of the Joint Venture Agreement (the "JVA") that governs the management of the JV (note 8), the Company remains the manager and operator of the JV and receives an arm's length fee for services rendered to the JV of $6.5 million per annum (originally $6.0 million, but adjusted annually for inflation). During the year ended December 31, 2021, the Company earned a service fee of $5.1 million (year ended December 31, 2020 - $4.9 million). For the year ended December 31, 2021, the service fee was comprised of a gross service fee of $6.3 million less withholding taxes payable in Ghana of $1.2 million (year ended December 31, 2020 - gross service fee of $6.1 million less withholding taxes of $1.2 million). As at December 31, 2021, the Company had a receivable due from the JV in respect of the service fee in the amount of $7.3 million, net of withholding taxes (December 31, 2020 - $2.7 million). Pending regulatory approval in Ghana of the 2021 service fee agreement, the Company expects to collect its service fee receivable in 2022. All transactions with related parties have occurred in the normal course of operations and were measured at the exchange amount agreed to by the parties. All amounts are unsecured, non-interest bearing and have no specific terms of settlement.

Disclosure of financial assets [text block]	7. Financial assets As part of the JV Transaction (note 8), the Company initially subscribed to 184.9 million non-voting fixed redemption price redeemable preferences shares in Shika Group Finance Limited (the "preference shares"), which were issued at a par value of $1 per redeemable share. The preference shares have no fixed redemption date. As these preference shares have no contractual fixed terms of repayment that arise on specified dates, they are measured at fair value through profit or loss at each reporting period-end. The following table summarizes the change in the carrying amount of the Company's preference shares held in the joint venture: December 31, 2021 December 31, 2020 Number of shares $ $ Balance, beginning of year 137,400,000 78,299 108,025 Fair value adjustment for the year - (873 ) 7,774 Redemption of preferred shares during the year (5,000,000 ) (5,000 ) (37,500 ) Balance, end of year 132,400,000 72,426 78,299 As at December 31, 2021, the Company re-measured the fair value of the redeemable preference shares to $72.4 million. Given that the AGM was unable to declare a mineral reserve at the balance sheet date (see Impairment testing in note 8), management's best estimate of the fair value of the preference shares was determined by applying a dollar per ounce (based on a range of market values for similar assets) to the JV's in-situ mineral resources, estimating the net realizable value of stockpiled ore and considering other working capital items (refer to note 8). For the year ended December 31, 2021, the Company recognized a downward fair value adjustment on its preference shares of $0.9 million in finance expense (year ended December 31, 2020 - $7.8 million positive fair value adjustment in finance income). The preference shares are classified as a Level 3 financial asset in the fair value hierarchy.

Investment In Joint Venture [Abstract]
Investment in joint venture [Text Block]	8. On July 31, 2018, the Company completed a transaction (the "JV Transaction") with a subsidiary of Gold Fields Limited ("Gold Fields"), following which: • the Company and Gold Fields each own a 45% economic interest in Asanko Gold Ghana Limited ("AGGL"), which owns the AGM, with the Government of Ghana retaining a 10% free-carried interest in the AGM; • the Company and Gold Fields each own a 50% interest in Adansi Gold Company (GH) Limited ("Adansi Ghana"), which owns a number of exploration licenses; and • the Company and Gold Fields each acquired a 50% interest in the JV entity, Shika Group Finance Limited ("JV Finco"). As the JV is structured within the legal entities of AGGL, Adansi Ghana and JV Finco, the JV represents a joint venture as defined under IFRS 11 - Joint Arrangements, and the Company commenced equity accounting for its interest in the JV effective July 31, 2018. The following table summarizes the change in the carrying amount of the Company's investment in the joint venture: December 31, 2021 December 31, 2020 $ $ Balance, beginning of year 59,159 - Company's share of the JV's net (loss) income for the year (51,528 ) 59,159 Impairment of investment in joint venture (7,631 ) - Balance, end of year - 59,159 Impairment of the AGM On February 25, 2022, the Company announced that recent gold recovery at the AGM had been lower than expected. The Company determined the AGM was not in a position to declare mineral reserves in its updated NI 43-101 filed on March 29, 2022, with an effective date of February 28, 2022. The Company considered these factors to represent an indicator of impairment of the MPP&E of the AGM. In addition, the AGM’s mine plan for 2022 contemplates a temporary deferral of mining activities in Q2 2022 following which only stockpile material will be processed for the balance of 2022. Accordingly, the Company assessed the recoverable amount of the AGM, which was based on management's best estimate of the fair value less cost to sell. Without defined mineral reserves published in a NI 43-101, management was unable to undertake a meaningful discounted cash flow analysis based on Life of Mine cash flows as had been done in previous impairment analyses. Therefore, management estimated the recoverable amount of the AGM by applying a fair value of $25 per ounce to the AGM’s Measured and Indicated resources. The fair value of $25 per ounce was estimated by reviewing market prices for similar assets while also considering risks specific to the AGM asset, including historical reclamation and workforce related costs. Stockpiles were valued based on the estimated selling price less remaining costs to process the ore. The fair value less cost to sell of the AGM CGU (on a 100% basis) was estimated to be $100.7 million. Management's estimate of the fair value of the AGM's MPP&E is classified as Level 3 in the fair value hierarchy. At December 31, 2021, the carrying value of the AGM’s MPP&E was $153.2 million greater than its estimated recoverable amount, therefore an impairment charge on MPP&E in this amount was recognized for the year ended December 31, 2021 (the Company's share of which was $ 68.9 In addition, as a result of lower expected recovery, the AGM also recorded a $22.8 million write-down of stockpile inventory to net realizable value (refer to note 8(ii)). Sensitivity analysis Due to the sensitivity of the recoverable amount to management judgments and estimates, specifically market comparable rates for in-situ mineral resources, as well as unforeseen factors, any significant change in key assumptions and inputs could result in changes in impairment charges to be recorded in future periods. The following table highlights the assumptions and estimates that management believes are most sensitive to estimating the recoverable amount. Any change in these assumptions and estimates could have a material impact on the estimated recoverable amount of the AGM. Assumption Per management's Sensitivity Impact on recoverable amount (100% basis) Increase ($'millions) Decrease ($'millions) Market value of in-situ resources $25/oz +/- $5/oz $14 $14 Impairment testing of Investment in associate recognized by the Company The Company recorded its share of the AGM's losses for the year ended December 31, 2021 of $51.5 million, which reduced the carrying value of the investment in the associate to $7.6 million as at December 31, 2021. Furthermore, as discussed in note 7, the value attributed to the preference shares was $72.4 million (compared to the par value of $132.4 million). The Company's management considered that the above noted impairment considerations identified at the JV level were also applicable to the carrying value of the Company's equity investment in the AGM JV. When considering the capital structure of the JV, specifically the face value of the preference shares, management concluded that the fair value attributed to the preference shares was indicative that no additional value would be available to equity interests in the JV. Accordingly, management estimated the recoverable amount of its equity investment in the JV to be nil at December 31, 2021 and as a result recognized an impairment charge of $7.6 million for the year ended December 31, 2021. Operating and financial results of the JV for the years ended December 31, 2021 and 2020 Summarized financial information for the Company's investment in the JV is outlined in the table below. All disclosures in this note 8 are on a 100% JV basis, unless otherwise indicated. The JV applies the same accounting policies as the Company.

All amounts in the following tables and descriptions are on a 100% basis. (i) Revenue AGGL has an offtake agreement with a special purpose vehicle of RK Mine Finance Trust I ("Red Kite") with the following details (the "Offtake Agreement"): - - - - - - During the year ended December 31, 2021, the AGM sold 216,076 ounces of gold to Red Kite in accordance with the Offtake Agreement (year ended December 31, 2020 - 243,807 ounces). As of December 31, 2021, the AGM has delivered 1,299,256 ounces to Red Kite under the Offtake Agreement. The Offtake Agreement was not affected by the JV Transaction and will remain in effect until all contracted ounces have been delivered to Red Kite or AGGL elects to terminate the Offtake Agreement and pay the associated fee. Included in revenue of the AGM is $0.6 million relating to by-product silver sales for the year ended December 31, 2021 (year ended December 31, 2020 - $0.9 million). (ii) The following is a summary of production costs by nature, on a 100% basis, incurred during the years ended December 31, 2021 and 2020: December 31, 2021 $ December 31, 2020 $ Raw materials and consumables (54,422 ) (54,588 ) Salary and employee benefits (37,449 ) (35,204 ) Contractors (net of deferred stripping costs) (135,244 ) (119,337 ) Change in stockpile, gold-in-process and gold dore inventories (7,825 ) 28,970 Insurance, government fees, permits and other (20,125 ) (17,161 ) Share-based compensation 7 (1,027 ) Total production costs (255,058 ) (198,347 ) During the year ended December 31, 2021, the AGM recognized a $26.4 million downward net realizable value adjustment to the carrying value of its stockpile inventory, of which $19.6 million was recorded as production costs and $6.8 million recorded as depreciation expense. The gold price assumption applied in the net realizable value calculation was $1,835 per ounce, and management estimated future costs of processing the stockpiles based upon historical and projected information. During the year ended December 31, 2020, the AGM recognized a $16.6 million reversal of previously recorded net realizable value adjustments on its stockpile inventory primarily due to an increase in gold prices during the year, of which $7.7 million was credited against production costs and $8.9 million credited against depreciation expense. All of the AGM's concessions are subject to a 5% gross revenue royalty payable to the Government of Ghana. The AGM's Akwasiso mining concession is also subject to an additional 2% net smelter return royalty payable to the previous owner of the mineral tenement, and the AGM's Esaase mining concession is also subject to an additional 0.5% net smelter return royalty payable to the Bonte Liquidation Committee.

The AGM deposits a reclamation deposit in a Ghanaian bank and the reclamation deposit is required to be held until receiving a final reclamation completion certificate from the EPA. The AGM is expected to be released from this requirement 45 days following the third anniversary of the date that the AGM receives a final completion certificate. The reclamation deposit accrues interest and is carried at $1.9 million at December 31, 2021 (December 31, 2020 - $1.9 million). Total security required to be provided to the EPA for the Obotan deposits totals $15.6 million and comprises a reclamation deposit of $4.7 million (including the $1.9 million previously paid) and a bank guarantee of $10.9 million, 50% of which was provided by the Company (note 12). The additional cash reclamation deposit of $2.8 million was paid in Q1 2022.

The PSUs vest in 1/3 increments every twelve months following the grant date for a total vesting period of three years and also contain a performance criterion applied to the number of units that vest on a yearly basis.

The phantom share units represent a financial liability, as they will be settled in cash, and are marked-to-market at each reporting period end and presented in the Statement of Financial Position as a long-term incentive plan liability. For the year ended December 31, 2021, the Company recognized share-based compensation expense of $0.2 million (year ended December 31, 2020 - $0.1 million).

Capital management [Text Block]	19. Capital management The Company's objectives in managing capital are to ensure that the Company has the financial capacity to support its operations with sufficient capability to manage unforeseen operational or industry developments, to ensure the Company has the capital and capacity to support the long-term growth strategies of the JV, and to provide returns for shareholders and benefits for other stakeholders. The Company defines capital that it manages as total shareholders' equity, being a total of $132.8 million as at December 31, 2021 (December 31, 2020 - $198.9 million). The Company is not subject to externally imposed capital requirements or covenants. The Company manages its capital structure and makes adjustments to it in light of general economic conditions, the risk characteristics of the underlying assets and the Company's working capital requirements associated with ongoing operations and corporate development plans. In order to maintain or adjust its capital structure, the Company entered into an ATM agreement (note 10(d)) under which the Company may, at its discretion and from time-to-time during the term of the ATM agreement, sell through the Agents common shares of the Company for aggregate gross proceeds to the Company of up to $50.0 million. As of December 31, 2021, no common shares have been issued under the Offering. The Company does not currently pay out dividends. The Board of Directors reviews and approves any material transactions out of the ordinary course of business, including proposals on acquisitions or other major investments or divestitures, as well as capital and operating budgets. The Company's investment policy is to invest its cash in highly liquid short-term interest-bearing investments with maturities of 180 days or less from the original date of acquisition. The Company has not made any changes to its policies and processes for managing capital during the year.

Financial instruments

Disclosure of detailed information about financial instruments [abstract]
Financial instruments [Text Block]	20. Financial instruments As at December 31, 2021, the Company's financial instruments consist of cash and cash equivalents, receivable due from related party, preferred shares in the JV, accounts payable and accrued liabilities and long-term incentive plan liabilities. The Company classifies cash and cash equivalents, the related party receivable and accounts payable and accrued liabilities as financial assets or liabilities and are measured at amortized cost. The preferred shares in the JV and long-term incentive plan liabilities are measured at fair value through profit or loss and fall within Level 3 of the fair value hierarchy as discussed below. The fair value hierarchy comprises: Level 1 - fair values based on unadjusted quoted prices in active markets for identical assets or liabilities; Level 2 - fair values based on inputs that are observable for the asset or liability, either directly or indirectly; and Level 3 - fair values based on inputs for the asset or liability that are not based on observable market data. There were no transfers between the levels during the years ended December 31, 2021 or 2020. The fair values of all financial assets and liabilities measured at amortized cost approximate their carrying values given their short-term to maturity. The risk exposure arising from these financial instruments is summarized as follows: (a) Credit risk is the risk of an unexpected loss if a customer or the issuer of a financial instrument fails to meet its contractual obligations. The Company is subject to credit risk on the cash and cash equivalent balances held at banks in Canada, South Africa, Isle of Man and Mali. The risk of loss associated with cash investments is considered to be low as the majority of the Company's cash and cash equivalents are held with highly rated banking institutions. As at December 31, 2021, the Company had a receivable due from the JV of $7.3 million (December 31, 2020 - $2.7 million). Credit risk associated with the related party receivable is considered to be low based on the liquidity of available funds of the JV. In addition, the Company is exposed to credit risk on its preferred share investments in the JV (note 7). With respect to the 132.4 million preference shares, credit risk is mitigated by monitoring the financial condition of the JV on a regular basis. The Company's maximum exposure to credit risk in relation to the preferred shares at the reporting date is the carrying value of the financial asset totaling $72.4 million. (b) Liquidity risk encompasses the risk that the Company cannot meet its financial obligations as they fall due. The Company manages liquidity risk through a rigorous planning and budgeting process, which is reviewed and updated on a regular basis, to help determine the funding requirements to support current operations, expansion and development plans, and by managing the Company's capital structure (note 19). By managing liquidity risk, the Company aims to ensure that it will have sufficient liquidity to settle obligations and liabilities as they fall due. Subsequent to the JV Transaction, the Company's only direct source of revenue is the service fee earned as operators of the AGM JV, as any free cash flows generated by AGM are no longer within the Company's exclusive control as the disposition of cash from the JV is governed by the JVA (note 8). However, through a combination of the Company's cash balance, cash flows from its investment in the JV, and the ongoing management fee receipts from the JV (note 6), the Company believes it is in a position to meet all working capital requirements, contractual obligations and commitments as they fall due. The Company's cash flows, however, and its ability to meet working capital requirements and contractual obligations are significantly influenced by the price of gold and the performance of the AGM. The Company aims to manage its liquidity by ensuring that, even in a low gold price environment, it can manage spending and provide adequate cash flow to meet all commitments. As at December 31, 2021, the Company had a cash and cash equivalents balance of $53.5 million (December 31, 2020 - $62.2 million) allowing it to settle current liabilities of $2.6 million (December 31, 2020 - $3.6 million) as they become due. (c) (i) Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. Given the change in methodology to estimate the fair value of the Company's preferred shares in the JV as at December 31, 2021, the Company is not exposed to any material interest rate risks with respect to its preference shares. During the year ended December 31, 2020, with other variables unchanged, a 1% decrease (increase) in the annualized interest rate would have resulted in a $3.6 million increase and $3.4 million decrease to the Company's preferred shares in the JV, respectively, and to the Company's after-tax net income for the year. The Company's cash and cash equivalents earn interest income at variable rates and accordingly future interest income is subject to fluctuations in short-term interest rates. A +/-1% change in short-term interest rates during the year would have resulted in a $0.6 million increase or decrease to the Company's interest income for the year ended December 31, 2021 (year ended December 31, 2020 - $0.6 million increase or decrease). (ii) As at December 31, 2021 and 2020, the Company's exposure to foreign currency risk was limited to the balances presented below. Acronyms of "ZAR" and "XOF" refer to the South African Rand and West African Franc, respectively. December 31, 2021 Foreign currency amount USD Equivalent C$(000s) ZAR (000s) XOF (000s) $ Cash and cash equivalents 2,615 645 21,958 2,130 Receivables 65 - - 51 Accounts payable and accrued liabilities (1,746 ) (379 ) (26,088 ) (1,439 ) Long-term incentive plan liabilities (1,971 ) - - (1,547 ) Lease liability (534 ) - - (419 ) Net exposure to foreign currency (1,571 ) 266 (4,130 ) (1,223 ) December 31, 2020 Foreign currency amount USD Equivalent C$(000s) ZAR (000s) $ Cash and cash equivalents 280 6,954 696 Receivables 37 43 32 Accounts payable and accrued liabilities (1,769 ) (436 ) (1,417 ) Long-term incentive plan liabilities (2,187 ) - (1,715 ) Lease liability (657 ) - (515 ) Net exposure to foreign currency (4,296 ) 6,561 (2,919 ) A +/-10% change in the prevailing exchange rates as at December 31, 2021, with all other variables held constant, would have resulted in a $0.1 million decrease (increase) to the Company's after-tax net income for the year ended December 31, 2021 (year ended December 31, 2020 - $0.3 million decrease (increase) to after tax net income). (iii) Price risk is the risk that future cash flows of a financial instrument will fluctuate because of changes in market prices, other than those arising from currency risk or interest rate risk. Future cash flows from the JV are expected to be received as redemptions of the Company's preference shares in the JV (note 7). Changes in the gold price may impact the fair value of the AGM's in-situ mineral resources. A +/- 10% change in the fair value per ounce of in-situ mineral resources of 2.9 million gold ounces, with all other variables held constant would have resulted in a $7.0 million decrease (increase) to the Company's after-tax net loss for the year ended December 31, 2021.

Significant Accounting Policies [Abstract]
Investments in joint arrangements [text block]	(a) The Company conducts a portion of its business through joint arrangements where the parties are bound by contractual arrangements establishing joint control and decisions about the activities that significantly affect the returns of the investee require unanimous consent. A joint arrangement is classified as either a joint operation or a joint venture, subject to the terms that govern each investor's rights and obligations in the arrangement. In a joint operation, the investor has rights and obligations to the separate assets and liabilities of the investee and in a joint venture, the investors have rights to the net assets of the joint arrangement. For a joint operation, the Company recognizes its share of the assets, liabilities, revenue, and expenses of the joint arrangement, while for a joint venture, the Company accounts for its investment in the joint arrangement using the equity method. Under the equity method, the Company's investment in a joint venture is initially recognized at cost and subsequently increased or decreased to recognize the Company's share of net earnings or losses of the joint venture, after any adjustments necessary for impairment losses after the initial recognition date. The total carrying amount of the Company's investment in a joint venture also includes any long-term debt interests which in substance form part of the Company's net investment. The Company's share of a joint venture's losses that are in excess of its investment are recognized only to the extent that the Company has incurred legal or constructive obligations or made payments on behalf of the joint venture. The Company's share of net earnings or losses of a joint venture are recognized in net earnings during the period. Dividends and repayment of capital received from a joint venture are accounted for as a reduction in the carrying amount of the Company's investment. Balances between the Company and its joint ventures are not eliminated. At the end of each reporting period, the Company assesses whether there is any objective evidence that an investment in a joint venture is impaired. Objective evidence includes observable data indicating there is a measurable decrease in the estimated future cash flows of the joint venture's operations. When there is objective evidence that an investment is impaired, the carrying amount of such investment is compared to its recoverable amount, being the higher of its fair value less costs of disposal and value-in-use. If the recoverable amount of an investment is less than the carrying amount, the carrying amount is reduced to its recoverable amount and a corresponding impairment loss is recognized in the period in which the relevant circumstances are identified. When an impairment loss reverses in a subsequent period, the carrying amount of the investment is increased to the revised estimate of the recoverable amount to the extent that the increased carrying amount does not exceed the carrying amount that would have been determined had an impairment loss not been previously recognized. A reversal of an impairment loss is recognized in net earnings in the period in which the reversal occurs. Similar to the assessment of impairment for subsidiaries, the Company reviews the mining properties and plant and equipment for a joint arrangement at the cash-generating unit level to determine whether there is any indication that these assets are impaired.
Foreign currency translation [Policy Text Block]	(b) Transactions in foreign currencies are initially recorded at the functional currency rate of exchange at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated at the functional currency rate of exchange at the date of the statement of financial position. Foreign exchange gains (losses) are recorded in the consolidated statement of operations and comprehensive income (loss) for the year. Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates as at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value is determined.
Cash and cash equivalents [Policy Text Block]	(c) Cash and cash equivalents consist of cash on hand and short-term investments with original maturity dates of less than ninety days or that are fully redeemable without penalty or loss of interest.
Inventories [Policy Text Block]	(d) Gold on hand, gold in process and stockpiled ore inventories are recorded at the lower of weighted average production cost and net realizable value. Production costs include the cost of raw materials, direct labour, mine-site overhead expenses and applicable depreciation and depletion. Net realizable value is calculated as the estimated price at the time of sale based on prevailing and long-term metal prices less estimated future costs to convert the inventories from their respective states into saleable form less estimated costs to sell. Production costs are included in work-in-process inventory based on current costs incurred up to the point of dore production. The costs of finished goods represent the costs of work-in-process inventories plus applicable treatment costs. The costs of inventories sold during the period are presented as production costs in the statement of operations and comprehensive income (loss) for the period. Additions to the cost of ore stockpiles are based on the related current cost of production for the period, while reductions in the cost of ore stockpiles are based on the weighted-average cost per tonne of ore in the stockpile. Stockpiles are segregated between current and non-current inventories in the consolidated statement of financial position based on the planned period of usage. Supplies and spare parts are valued at the lower of weighted-average cost and net realizable value. Replacement costs of materials and spare parts are generally used as the best estimate of net realizable value. Provisions are recorded to reduce the carrying amount of materials and spare parts inventory to net realizable value to reflect current intentions for the use of redundant or slow-moving items. Provisions for redundant and slow-moving items are made by reference to specific items of inventory. The Company reverses write-downs where there is a subsequent increase in net realizable value and where the inventory is still on hand.
Mineral properties, plant and equipment ("MPP&E") [Policy Text Block]	(e) (i) Recognition Capitalized costs of mining properties include the following: - - - - - - Stripping costs In open pit mining operations, it is necessary to incur costs to remove overburden and other mine waste materials in order to access the ore from which minerals can be extracted economically. Stripping costs incurred in order to provide initial access to the ore body (referred to as pre-production stripping) are capitalized as incurred. Stripping costs incurred during the production stage of an open pit mine are accounted for as production costs in the consolidated statement of operations and comprehensive income during the period that the stripping costs were incurred, unless these costs provide a future economic benefit. Production phase stripping costs are considered to generate a future economic benefit when (i) it is probable that future economic benefit associated with the stripping activity will flow to the entity; (ii) the entity can identify the component of the ore body for which access has been improved; and (iii) the costs relating to the stripping activity associated with that component can be measured reliably. These costs are capitalized as mineral properties, plant and equipment. Production costs are allocated between inventory produced and the stripping asset based on the volume of waste extracted compared with the expected volume, for a given volume of ore production. Stripping costs incurred and capitalized during the production phase are depleted using the units-of-production method over the proven and probable reserves (ore tonnes) of the component of the ore body to which access has been improved as a result of the specific stripping activity. Management reviews the estimates of the waste and ore in each identified component of operating open pit mines at the end of each financial year, and when events and circumstances indicate that such a review should be made. Deferred stripping assets are written-down to their recoverable amount when their carrying value is not considered supportable. Changes to the estimated identification of components and the associated waste and ore within each component are accounted for prospectively. Exploration and evaluation expenditures Exploration and evaluation expenditures include the costs of acquiring rights to explore, exploratory drilling and related exploration costs incurred on sites without an existing mine and on areas outside the boundary of a known mineral deposit which contain proven and probable reserves. Exploration and evaluation expenditures incurred on a mineral deposit, with the exception of acquisition costs and costs arising from the recognition of an asset retirement provision, are expensed as incurred up to the date of establishing that costs incurred on a mineral deposit are technically feasible and commercially viable. Expenditures incurred on a mineral deposit subsequent to the establishment of its technical feasibility and commercial viability are capitalized and included in the carrying amount of the related mining property. The technical feasibility and commercial viability of a mineral deposit is assessed based on a combination of factors, such as, but not limited to: - - - - Borrowing costs Borrowing costs directly relating to the financing of qualifying assets are added to the capitalized cost of those related assets until such time as the assets are substantially ready for their intended use or sale which, in the case of mining properties, is when they are capable of commercial production. Where funds have been borrowed specifically to finance a project, the amount capitalized represents the actual borrowing costs incurred. Where the funds used to finance a project form part of general borrowings, the amount capitalized is calculated using a weighted average of rates applicable to relevant general borrowings of the Company during the period. Capitalized borrowing costs are depreciated over the life of the related asset. All other borrowing costs are recognized in the consolidated statement of operations and comprehensive income in the year in which they are incurred. Borrowing costs are included as part of interest paid in the statement of cash flows. Depletion Mineral properties in production are depleted on a mine-by-mine basis using the units-of-production method over the mine's estimated proven and probable reserves, with the exception of deferred stripping which is depleted using the unit-of-production method over the reserves that directly benefit from the specific stripping activity and will commence when the mine is capable of operating in the manner intended by management. In the event proven and probable reserves are not identified management will use their best estimate from internally generated information. The Company uses a number of criteria to assess whether the mine is in the condition necessary for it to be capable of operating in a manner intended by management. These criteria include, but are not limited to: - - - - - Mineral properties in development are not depleted. (ii) Recognition The cost of plant and equipment consists of the purchase price, costs directly attributable to the delivery of the asset to the location and the condition necessary for it to be capable of operating in the manner intended by management, including the cost of testing whether these assets are operating in the manner intended by management. Subsequent costs are included in the asset's carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Company and the cost can be measured reliably. Where significant components of an asset have differing useful lives, depreciation is calculated on each separate component. Depreciation Depreciation of an asset begins when it is available for use, i.e. when it is in the location and condition necessary for it to be capable of operating in the manner intended by management. The carrying amounts of plant and equipment are depreciated using either the straight-line or units-of-production method over the shorter of the estimated useful life of the asset or the life of mine. The significant classes of depreciable plant and equipment and their estimated useful lives are as follows: Asset Class Estimated Useful Life Fixed plant & related components and infrastructure Units of production over life of mine Mobile and other mine equipment components 3 to 12 years Computer equipment and software 3 years Right-of-use assets Straight-line over lease term Management reviews the estimated useful lives, residual values and depreciation methods of the Company's plant and equipment at the end of each financial year, and when events and circumstances indicate that such a review should be made. Changes to estimated useful lives, residual values or depreciation methods resulting from such review are accounted for prospectively. Major maintenance and repairs Expenditure on major maintenance and repairs includes the cost of replacement parts of assets and overhaul costs. Where an asset or part of an asset is replaced and it is probable that future economic benefits associated with the item will be available to the Company, that expenditure is capitalized and the carrying amount of the item replaced derecognized. Similarly, overhaul costs associated with major maintenance are capitalized when it is probable that future economic benefits will be available and any remaining carrying amounts of the cost of previous overhauls are derecognized. All other maintenance and repair costs are expensed as incurred. (iii) The carrying amounts of assets included in mineral properties, plant and equipment are reviewed for impairment when events and changes in circumstances indicate that the related carrying amounts may not be recoverable. If any such indication exists, the recoverable amount of the relevant cash-generating unit ("CGU") is estimated in order to determine the extent of impairment. A CGU is the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. The carrying amounts of the CGUs are compared to their recoverable amounts where the recoverable amount is the higher of value-in-use ("VIU") and fair value less costs to sell ("FVLCS"). FVLCS is defined as the amount that would be obtained from the sale of the asset in an orderly transaction between market participants at the measurement date. VIU is determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset in its present form and from its ultimate disposal. The fair value of mine sites is generally determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset, including any expansion prospects. If a reliable estimate of future cash flows cannot be made, then fair value is determined by reference to market prices for comparable assets. If the recoverable amount of an asset (or CGU) is estimated to be less than its carrying amount, the carrying amount is reduced to its recoverable amount. An impairment is recognized immediately in the consolidated statement of operations and comprehensive income. Mineral properties, plant and equipment that have been impaired are tested for possible reversal of the impairment whenever events or changes in circumstances indicate that the impairment may have reversed. When an impairment loss reverses in a subsequent period, the revised carrying amount shall not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset previously, less subsequent depletion and depreciation. Reversals of impairment losses are recognized in the consolidated statements of operations in the period in which the reversals occur. (iv) Upon disposal or abandonment, the carrying amounts of mineral properties and plant and equipment are derecognized and any associated gains or losses are recognized in the consolidated statement of operations and comprehensive income.
Leases [Policy text block]	(f) 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. To assess whether a contract conveys the right to control the use of an identified asset, the Company assesses whether it has the right to obtain substantially all of the economic benefits from and to direct the use of the identified asset. At commencement or on modification of a contract that contains a lease component, the Company allocates the consideration in the contract to each lease component on the basis of its relative stand-alone prices. 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 comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset, or the site on which it is located, less any lease incentives received. The right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the end of the lease term, unless the lease transfers ownership of the underlying asset to the Company by the end of the lease term or the cost of the right-of-use asset reflects that the Company will exercise a purchase option. In that case, the right-of-use asset will be depreciated over the useful life of the underlying asset, which is determined on the same basis as those of property and equipment. In addition, the right-of-use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability. 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. Generally, the Company uses its incremental borrowing rate as the discount rate. The Company determines its incremental borrowing rate by obtaining interest rates from various external financing sources and makes certain adjustments to reflect the terms of the lease and type of the asset leased. Lease payments included in the measurement of the lease liability comprise the following: • fixed payments, including in-substance fixed payments; • variable lease payments that depend on an index or a 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 liability is measured at amortized cost using the effective interest method. It 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 estimate of the amount expected to be payable under a residual value guarantee, if the Company changes its assessment of whether it will exercise a purchase, extension or termination option, or if there is a revised in-substance fixed lease payment. 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 the consolidated statement of operations and comprehensive income if the carrying amount of the right-of-use asset has been reduced to zero. Short-term leases and leases of low-value assets The Company has elected not to recognize right-of-use assets and lease liabilities for leases of low-value assets and short-term leases, including office equipment. The Company recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term.
Provisions [Policy Text Block]	(g) General Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. Where the Company expects some or all of a provision to be reimbursed, for example under an insurance contract, the reimbursement is recognized as a separate asset, but only when the reimbursement is virtually certain. The expense relating to any provision is presented in the consolidated statement of operations and comprehensive income net of any reimbursement. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects where appropriate, the risks specific to the liability. Where discounting is used, the increase in the provision due to the passage of time is recognized as finance expense in the consolidated statement of operations and comprehensive income. Asset retirement provisions An obligation to incur restoration, rehabilitation and environmental costs arises when environmental disturbance is caused by the exploration, development or ongoing production of a mineral property interest. The Company records the estimated present value of future cash flows associated with site reclamation as a liability when the liability is incurred with a corresponding increase in the carrying value of the related assets. Discount rates using a pre-tax, risk-free rate that reflect the time value of money are used to calculate the net present value. The liability is accreted over time to reflect the unwinding of the discount with the accretion expense included in finance costs in the consolidated statement of operations and comprehensive income (loss). Changes in estimates or circumstances include changes in legal or regulatory requirements, increased obligations arising from additional mining and exploration activities, changes to cost estimates, changes to the discount rate and changes to the risk-free interest rates.
Revenue from contracts with customers [Text Block]	(h) Revenue is derived from the sale of gold and by-products. Revenue is recognized for contracts with customers when there is persuasive evidence that all of the following criteria are met: - - - - - Revenue from gold and any by-product metals is generally recorded at the time of physical delivery of the refined gold, which is also the date when control of the gold passes to the customer. Revenue from saleable gold produced during the testing phase of production activities, and the cost of producing those items, is recognized in profit or loss.
Government royalties [Policy Text Block]	(i) Royalty payments to governments which are based on gross revenue are not considered income taxes and are recognized as an expense in the statement of operations and comprehensive income (loss).
Financial instruments [Policy Text Block]	(j) (i) Recognition and measurement The Company recognizes a financial asset in its statement of financial position when the Company becomes party to the contractual provisions of the instrument. All financial assets are initially recorded at fair value plus directly attributable transaction costs and classified as either (i) financial assets subsequently measured at amortized cost, (ii) financial assets subsequently measured at fair value through other comprehensive income or (iii) financial assets subsequently measured at fair value through profit or loss. The basis of classification takes into consideration both the Company's business model for managing and the contractual cash flow characteristics of the financial assets. A financial asset is measured at amortized cost if 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 give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. A financial asset is measured at fair value through other comprehensive income if the financial asset is held within a business model whose objective is achieved by both collecting 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. A financial asset is measured at fair value through profit or loss unless it is measured at amortised cost or at fair value through other comprehensive income. Fair value changes in financial assets classified as fair value through profit or loss, if any, are recognized in the consolidated statement of operations and comprehensive income. Derecognition A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is derecognized when: - - (ii) Recognition and measurement All financial liabilities are initially recorded at fair value less transaction costs. All financial liabilities are subsequently measured at amortized cost using the effective interest method, except for: - - - - - Business combinations An entity may, at initial recognition, irrevocably designate a financial liability as measured at fair value through profit or loss when a contract contains one or more embedded derivatives, or when doing so results in more relevant information, because either (a) it eliminates or significantly reduces a measurement or recognition inconsistency (i.e. an accounting mismatch); or (b) a group of financial liabilities or financial assets and financial liabilities is managed and its performance is evaluated on a fair value basis. Fair value changes of financial liabilities classified as fair value through profit or loss, if any, are recognized in the consolidated statement of operations and comprehensive income.
Share-based compensation [Policy Text Block]	(k) The Company has a share option plan and share unit plan which are described in note 11. For share options, the fair value of share-based compensation awards is determined at the date of grant using the Black-Scholes option pricing model. The Company records all share-based compensation for options using the fair value method with graded vesting. Under the fair value method, share-based payments are measured at the fair value of the consideration received or the fair value of the equity instruments issued or liabilities incurred, whichever is more reliably measurable, and are charged over the vesting period to the consolidated statement of operations and comprehensive income. The offset is credited to Equity reserves ratably over the vesting period, after adjusting for the number of awards that are expected to vest. Expenses recognized for forfeited awards are reversed. For awards that are cancelled, any expense not yet recognized is recognized immediately in the statement of operations and comprehensive income. Where the terms of an equity-settled award are modified, as a minimum an expense is recognized as if the terms had not been modified over the original vesting period. In addition, an expense is recognized for any modification which increases the total fair value of the share-based payment arrangement as measured at the date of modification, over the remainder of the vesting period. For cash-settled share-based payments (note 11), the Company measures the goods or services acquired and the liability incurred at the fair value of the liability. The corresponding share-based compensation expense is recognized over the vesting period of the award. As these awards will be settled in cash, the liability is remeasured at fair value at each reporting period and at the date of settlement, with changes in fair value recognized in the consolidated statement of operations and comprehensive income in the period incurred.
Income taxes [Policy Text Block]	(l) Income tax on the profit or loss for the periods presented comprises current and deferred income tax. Income tax is recognized in the consolidated statement of operations and comprehensive income except to the extent that it relates to items recognized directly in equity, in which case it is recognized in equity. Current income tax expense is the expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted at period end, adjusted for amendments to tax payable with regards to previous years. Deferred income tax is recognized in respect of unused tax losses, tax credits and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, based on the tax rates that have been substantively enacted at the reporting date. A deferred income tax asset is recognized only to the extent that it is probable that future taxable profits will be available against which the asset can be utilized. To the extent that the Company does not consider it probable that a future income tax asset will be recovered, it does not recognize the asset. Deferred income tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the Company intends to settle its tax assets and liabilities on a net basis. The Company records foreign exchange gains and losses representing the impacts of movements in foreign exchange rates on the tax bases of non-monetary assets and liabilities which are denominated in foreign currencies. Foreign exchange gains and losses relating to the translation of the deferred income tax balance from local statutory accounts to functional currency accounts are included in deferred income tax expense or recovery in the consolidated statement of operations and comprehensive income.
Income per share [Policy Text Block]	(m) Basic income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. The computation of diluted income per share assumes the conversion, exercise or contingent issuance of securities only when such conversion, exercise or issuance would have a dilutive effect on income per share. For this purpose, the treasury stock method is used for the assumed proceeds upon the exercise of stock options that are used to purchase common shares at the average market price during the period.
