Nature and continuance of operations [Text Block]	1. Nature and continuance of operations Giga Metals Corporation (the “Company” or “Giga Metals”) was incorporated on January 17, 1983, under the laws of the province of British Columbia, Canada, and its principal activity is the acquisition and exploration of mineral properties in Canada. The Company’s common shares are listed for trading on the TSX Venture Exchange (“TSXV”) under the symbol “GIGA”. The head office, principal address and records office of the Company are located at 700 West Pender Street, Suite 203, Vancouver, British Columbia, Canada, V6C 1G8. The Company’s registered address is 885 West Georgia Street, Suite 800, Vancouver, British Columbia, Canada, V6C 3H1. These consolidated financial statements have been prepared on the assumption that the Company and its subsidiary will continue as a going concern, meaning it will continue in operation for the foreseeable future and will be able to realize assets and discharge liabilities in the ordinary course of operations. As at December 31, 2018, the Company's accrued deficit was $54,329,010, the Company had not advanced its mineral properties to commercial production and the Company has no other source of revenue from its operations. The Company’s continuation as a going concern is dependent upon the successful results from its mineral property exploration activities and its ability to attain profitable operations and generate funds there from and/or raise equity capital or borrowings sufficient to meet current and future obligations. Management intends to finance operating costs over the next twelve months using existing cash and the proceeds from the sale of marketable securities (Note 5).

Significant accounting policies and basis of preparation [Text Block]	2. Significant accounting policies and basis of preparation These financial statements were authorized for issue on April 23, 2019 by the directors of the Company. Statement of compliance with International Financial Reporting Standards The consolidated financial statements of the Company comply with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) and interpretations of the International Financial Reporting Interpretations Committee (“IFRIC”). Basis of preparation The consolidated financial statements of the Company have been prepared on an accrual basis and are based on historical costs, modified where applicable. The consolidated financial statements are presented in Canadian dollars unless otherwise noted. Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned Canadian subsidiary, Canadian Metals Exploration Ltd. Inter-company balances and transactions, including unrealized income and expenses arising from inter-company transactions, are eliminated on consolidation. Significant estimates and assumptions The preparation of financial statements in accordance with IFRS requires the Company to make estimates and assumptions concerning the future. The Company’s management reviews these estimates and underlying assumptions on an ongoing basis, based on experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Revisions to estimates are adjusted prospectively in the period in which the estimates are revised. Estimates and assumptions where there is significant risk of material adjustments to assets and liabilities in future accounting periods include the useful lives of equipment, the recoverability of the carrying value of exploration and evaluation assets, fair value measurements for financial instruments and share-based payments, the recoverability and measurement of deferred tax assets, provisions for restoration and environmental obligations and contingent liabilities. Significant judgments The preparation of financial statements in accordance with IFRS requires the Company to make judgments, apart from those involving estimates, in applying accounting policies. The most significant judgments in applying the Company’s financial statements include: - The assessment of the Company’s ability to continue as a going concern and whether there are events or conditions that may give rise to significant uncertainty; - the classification / allocation of expenditures as exploration and evaluation expenditures or operating expenses; and - the classification of financial instruments. Cash and cash equivalents Cash and cash equivalents include cash and highly liquid investments held in the form of money market investments and certificates of deposit with investment terms that allow for penalty free redemption after one month. Exploration and evaluation expenditures Costs incurred before the Company has obtained the legal rights to explore an area are expensed as incurred. Exploration and evaluation expenditures include the costs of acquiring licenses and costs associated with exploration and evaluation activity. Option payments are considered acquisition costs provided that the Company has the intention of exercising the underlying option. Property option agreements are exercisable entirely at the option of the optionee. Therefore, option payments (or recoveries) are recorded when payment is made (or received) and are not accrued. Exploration and evaluation expenditures are capitalized. The Company capitalizes costs to specific blocks of claims or areas of geological interest. Government tax credits received are recorded as a reduction to the cumulative costs incurred and capitalized on the related property. Exploration and evaluation assets are tested for impairment if facts or circumstances indicate that impairment exists. Examples of such facts and circumstances are as follows: - the period for which the Company has the right to explore in the specific area has expired during the period or will expire in the near future, and is not expected to be renewed; - substantive expenditure on further exploration for and evaluation of mineral resources in the specific area is neither budgeted nor planned; - exploration for and evaluation of mineral resources in the specific area have not led to the discovery of commercially viable quantities of mineral resources and the entity has decided to discontinue such activities in the specific area; and - sufficient data exist to indicate that, although a development in the specific area is likely to proceed, the carrying amount of the exploration and evaluation asset is unlikely to be recovered in full from successful development or by sale. After technical feasibility and commercial viability of extracting a mineral resource are demonstrable, the Company stops capitalizing expenditures for the applicable block of claims or geological area of interest and tests the asset for impairment. The capitalized balance, net of any impairment recognized, is then reclassified to either tangible or intangible mine development assets according to the nature of the asset. Share-based payments The Company operates an employee stock option plan. Share-based payments to employees are measured at the fair value of the instruments issued and amortized over the vesting periods. Share-based payments to non-employees are measured at the fair value of goods or services received or the fair value of the equity instruments issued, if it is determined the fair value of the goods or services cannot be reliably measured, and are recorded at the date the goods or services are received. The corresponding amount is recorded to the share-based payment reserve. The fair value of options is determined using the Black–Scholes option pricing model which incorporates all market vesting conditions. The number of shares and options expected to vest is reviewed and adjusted at the end of each reporting period such that the amount recognized for services received as consideration for the equity instruments granted shall be based on the number of equity instruments that eventually vest. Loss per share Basic loss per share is calculated by dividing the loss attributable to common shareholders by the weighted average number of common shares outstanding in the period. For all periods presented, the loss attributable to common shareholders equals the reported loss attributable to owners of the Company. Diluted loss per share is calculated by the treasury stock method. Under the treasury stock method, the weighted average number of common shares outstanding for the calculation of diluted loss per share assumes that the proceeds to be received on the exercise of dilutive share options and warrants are used to repurchase common shares at the average market price during the period. Recognition of Financial Instruments The Company recognizes a financial asset or financial liability on the statement of financial position when it becomes a party to the contractual provisions of the financial instrument. The Company classifies its financial instruments in the following categories: at fair value through profit and loss (“FVTPL”), at fair value through other comprehensive income (loss) (“FVTOCI”) or at amortized cost. The Company determines the classification of financial assets at initial recognition. The classification of debt instruments is driven by the Company’s business model for managing the financial assets and their contractual cash flow characteristics. Equity instruments that are held for trading are classified as FVTPL. For other equity instruments, on the day of acquisition the Company can make an irrevocable election (on an instrument-by-instrument basis) to designate them as at FVTOCI. Financial liabilities are measured at amortized cost, unless they are required to be measured at FVTPL (such as instruments held for trading or derivatives) or if the Company has opted to measure them at FVTPL. Financial assets at FVTOCI Investments in equity instruments designated at FVTOCI are initially recognized at fair value plus transaction costs. Subsequently they are measured at fair value, with both realized and unrealized gains and losses recognized in other comprehensive income (loss) in the period in which they arise. Financial assets and liabilities at amortized cost Financial assets and liabilities at amortized cost are initially recognized at fair value plus or minus transaction costs, respectively, and subsequently carried at amortized cost less any impairment. Financial assets and liabilities at FVTPL Financial assets and liabilities carried at FVTPL are initially recorded at fair value and transaction costs are expensed in profit or loss. Realized and unrealized gains and losses arising from changes in the fair value of the financial assets and liabilities held at FVTPL are included in profit or loss in the period in which they arise. Where management has opted to recognize a financial liability at FVTPL, any changes associated with the Company’s own credit risk will be recognized in other comprehensive income (loss). Impairment of financial assets at amortized cost The Company recognizes a loss allowance for expected credit losses on financial assets that are measured at amortized cost. At each reporting date, the Company measures the loss allowance for the financial asset at an amount equal to the lifetime expected credit losses if the credit risk on the financial asset has increased significantly since initial recognition. If at the reporting date, the financial asset has not increased significantly since initial recognition, the Company measures the loss allowance for the financial asset at an amount equal to the twelve month expected credit losses. The Company shall recognize in the profit or loss, as an impairment gain or loss, the amount of expected credit losses (or reversal) that is required to adjust the loss allowance at the reporting date to the amount that is required to be recognized. Derecognition of financial assets and liabilities The Company derecognizes financial assets only when the contractual rights to cash flows from the financial assets expire, or when it transfers the financial assets and substantially all of the associated risks and rewards of ownership to another entity. Gains and losses on derecognition are generally recognized in profit or loss in the period in which they arise. However, gains and losses on derecognition of financial assets designated as FVTOCI are recorded in other comprehensive income (loss) in the period in which they arise. Cumulative gains and losses on derecognized financial assets designated as FVTOCI are reclassified from accumulated other comprehensive income (loss) to deficit. The Company derecognizes financial liabilities only when its obligations under the financial liabilities are discharged, cancelled or expired. Generally, the difference between the carrying amount of the financial liability derecognized and the consideration paid and payable, including any non-cash assets transferred or liabilities assumed, is recognized in profit or loss. Impairment of assets The carrying amount of the Company’s assets (which include equipment and exploration and evaluation assets) is reviewed at each reporting date to determine whether there is any indication of impairment. If such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss. An impairment loss is recognized whenever the carrying amount of an asset or its cash generating unit exceeds its recoverable amount. Impairment losses are recognized in the statement of comprehensive income (loss). The recoverable amount of assets is the greater of an asset’s fair value less cost to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects the current market assessments of the time value of money and the risks specific to the asset. For an asset that does not generate cash inflows largely independent of those from other assets, the recoverable amount is determined for the cash-generating unit to which the asset belongs. An impairment loss is only reversed if there is an indication that the impairment loss may no longer exist and there has been a change in the estimates used to determine the recoverable amount. Any reversal of impairment cannot increase the carrying value of the asset to an amount higher than the carrying amount that would have been determined had no impairment loss been recognized in previous years. Assets that have an indefinite useful life are not subject to amortization and are tested annually for impairment. Income taxes Current income tax: Current income tax relating to items recognized directly in other comprehensive income or equity is recognized in other comprehensive income or equity and not in profit or loss. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate. Deferred income tax: The carrying amount of deferred income tax assets is reviewed at the end of each reporting period and recognized only to the extent that it is probable that sufficient taxable profit will be available to allow all or part of the deferred income tax asset to be utilized. Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply to the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. Deferred income tax assets and deferred income tax liabilities are offset, if a legally enforceable right exists to set off current tax assets against current income tax liabilities and the deferred income taxes relate to the same taxable entity and the same taxation authority. Flow-through shares: To the extent that the Company has suitable unrecognized deductible temporary differences, an offsetting recovery of deferred income taxes would be recorded. Restoration and environmental obligations The Company recognizes liabilities for statutory, contractual, constructive or legal obligations associated with the retirement of long-term assets, when those obligations result from the acquisition, construction, development or normal operation of the assets. The net present value of future restoration cost estimates arising from the decommissioning of plant and other site preparation work is capitalized to the related asset along with a corresponding increase in the restoration provision in the period incurred. Discount rates using a pre-tax rate that reflect the time value of money are used to calculate the net present value. The Company’s estimates of restoration costs could change as a result of changes in regulatory requirements, discount rates and assumptions regarding the amount and timing of the future expenditures. These changes are recorded directly to the related asset with a corresponding entry to the restoration provision. The Company’s estimates are reviewed annually for changes in regulatory requirements, discount rates, effects of inflation and changes in estimates. Changes in the net present value, excluding changes in the Company’s estimates of restoration costs, are charged to the statement of comprehensive loss for the period. The net present value of restoration costs arising from subsequent site damage that is incurred on an ongoing basis during production are charged to the statement of comprehensive loss in the period incurred. The costs of restoration projects that were included in the provision are recorded against the provision as incurred. The costs to prevent and control environmental impacts at specific properties are capitalized in accordance with the Company’s accounting policy for exploration and evaluation assets. At December 31, 2018 and 2017, the Company had no material restoration and environmental obligations. Equipment Equipment is stated at historical cost less accumulated depreciation and accumulated impairment losses. 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 of the item can be measured reliably. The carrying amount of the replaced part is derecognized. All other repairs and maintenance are charged to the statement of comprehensive income (loss) during the financial period in which they are incurred. Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognized in the statement of comprehensive income (loss). Amortization is calculated on a declining balance method to write off the cost of the assets to their residual values over their estimated useful lives. The amortization rates applicable to each category of equipment are as follows: Class of equipment Amortization rate Motor vehicles 30% declining balance Computer equipment 30% declining balance Exploration and office equipment 20% declining balance

Adoption of new accounting standards and standards issued but not yet effective [Text Block]	3. Adoption of new accounting standards and standards issued but not yet effective IFRS 9, Financial Instruments This standard replaces IAS 39 Financial Instruments: Recognition and Measurement and became effective for the Company on January 1, 2018. IFRS 9 includes requirements for classification and measurement of financial assets and financial liabilities; impairment methodology for financial instruments; and general hedge accounting. IFRS 9 has specific requirements for whether debt instruments are accounted for at amortized cost, fair value through other comprehensive income or fair value through profit or loss. IFRS 9 requires equity instruments to be measured at fair value through profit or loss unless an irrevocable election is made to measure them at fair value through other comprehensive income, which results in changes in fair value not being recycled to the income statement. The adoption of this standard did not have a material measurement or disclosure impact on the Company’s financial statements. There were no marketable securities held at December 31, 2017. The following table shows the original classification under IAS 39 and the new classification under IFRS 9: Financial assets/ Original Classification New classification liabilities IAS 39 IFRS 9 Cash and cash equivalents Loans and receivables Financial asset at amortized cost Receivables Loans and receivables Financial asset at amortized cost Trade payables Non-derivative financial liabilities Financial liability at amortized cost IFRS 16, Leases The new standard eliminates the classification of leases as either operating or finance leases for a lessee. Instead all leases are capitalized by recognizing the present value of lease payments and recognizing an asset and a financial liability representing an obligation to make future lease payments. The principles in IFRS 16 provide a more consistent approach to acquiring the use of an asset whether by leasing or purchasing an asset. The new leasing standard is applicable to all entities and will supersede current lease accounting standards under IFRS. IFRS 16 is mandatory for annual periods beginning on or after January 1, 2019. The Company has assessed the expected impact of IFRS 16 on its financial statements and has concluded that there will be an increase in assets and liabilities of approximately $325,000.

Financial instruments and financial risk management [Text Block]	14. Financial instruments and financial risk management The Company is exposed in varying degrees to a variety of financial instrument related risks. The Board of Directors approves and monitors the risk management processes, inclusive of documented investment policies, counterparty limits, and controlling and reporting structures. The type of risk exposure and the way in which such exposure is managed is provided as follows: Credit risk Credit risk is the risk that one party to a financial instrument will fail to discharge an obligation and cause the other party to incur a financial loss. The Company’s primary exposure to credit risk is on its cash held in bank accounts. All of the cash is deposited in bank accounts held with one major bank in Canada. Since all of the Company’s cash is held by one bank there is a concentration of credit risk. This risk is managed by using major banks that are high credit quality financial institutions as determined by rating agencies. The Company’s secondary exposure to risk is on its other receivables. This risk is minimal as receivables consist primarily of refundable government taxes. Liquidity risk Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company has a planning and budgeting process in place to help determine the funds required to support the Company’s normal operating requirements on an ongoing basis. The Company ensures that there are sufficient funds to meet its short-term business requirements, taking into account its anticipated cash flows from operations and its holdings of cash and cash equivalents as well as marketable securities. Historically, the Company's sole source of funding has been the issuance of equity securities for cash, primarily through private placements. The Company’s access to financing is always uncertain. There can be no assurance of continued access to significant equity funding. The following is an analysis of the contractual maturities of the Company’s non-derivative financial liabilities as at December 31, 2018: Within one Between one year and five More than years five years Trade payables and accrued liabilities $ 312,981 $ - $ - Foreign exchange risk Foreign currency risk is the risk that the fair values of future cash flows of a financial instrument will fluctuate because they are denominated in currencies that differ from the respective functional currency. The Company does not have any direct exposure to foreign exchange risk. Interest rate risk Interest rate risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Company does not have any significant interest rate risk. Other Price Risk Other price risk is the risk that the fair value of a financial instrument changes due to market risks other than foreign exchange risk or interest rate risk. The Company is exposed to changes in the fair value of the Cobalt 27 common shares. At December 31, 2018, the Company had 813,200 Cobalt 27 common shares that trade on the TSX-V under the trading symbol “KBLT”. At December 31, 2018, the value of the KBLT common shares was $3.30 per share or $2,683,560. A reasonable change in fair value of 10% would result in a change in the income (loss) for the period of $268,356.

Financial instruments measured at fair value are classified into one of three levels in the fair value hierarchy according to the relative reliability of the inputs used to estimate the fair values. The three levels of the fair value hierarchy are: • Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities; • Level 2 – Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly; and • Level 3 – Inputs that are not based on observable market data. The following is an analysis of the Company’s financial assets measured at fair value as at December 31, 2018 and 2017: As at December 31, 2018 Level 1 Level 2 Level 3 Cash $ 405,849 $ - $ - Marketable securities $ 2,683,560 $ - $ - Total $ 3,089,409 $ - $ - As at December 31, 2017 Level 1 Level 2 Level 3 Cash $ 4,066,588 $ - $ -

Summary of Significant Accounti

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Statements [Line Items]
Statement of compliance with International Financial Reporting Standards [Policy Text Block]	Statement of compliance with International Financial Reporting Standards The consolidated financial statements of the Company comply with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) and interpretations of the International Financial Reporting Interpretations Committee (“IFRIC”).
Basis of preparation [Policy Text Block]	Basis of preparation The consolidated financial statements of the Company have been prepared on an accrual basis and are based on historical costs, modified where applicable. The consolidated financial statements are presented in Canadian dollars unless otherwise noted.
Consolidation [Policy Text Block]	Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned Canadian subsidiary, Canadian Metals Exploration Ltd. Inter-company balances and transactions, including unrealized income and expenses arising from inter-company transactions, are eliminated on consolidation.
Significant estimates and assumptions [Policy Text Block]	The preparation of financial statements in accordance with IFRS requires the Company to make estimates and assumptions concerning the future. The Company’s management reviews these estimates and underlying assumptions on an ongoing basis, based on experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Revisions to estimates are adjusted prospectively in the period in which the estimates are revised. Estimates and assumptions where there is significant risk of material adjustments to assets and liabilities in future accounting periods include the useful lives of equipment, the recoverability of the carrying value of exploration and evaluation assets, fair value measurements for financial instruments and share-based payments, the recoverability and measurement of deferred tax assets, provisions for restoration and environmental obligations and contingent liabilities.
Significant judgments [Policy Text Block]	Significant judgments The preparation of financial statements in accordance with IFRS requires the Company to make judgments, apart from those involving estimates, in applying accounting policies. The most significant judgments in applying the Company’s financial statements include: - The assessment of the Company’s ability to continue as a going concern and whether there are events or conditions that may give rise to significant uncertainty; - the classification / allocation of expenditures as exploration and evaluation expenditures or operating expenses; and - the classification of financial instruments.
Cash and cash equivalents [Policy Text Block]	Cash and cash equivalents Cash and cash equivalents include cash and highly liquid investments held in the form of money market investments and certificates of deposit with investment terms that allow for penalty free redemption after one month.
Exploration and evaluation expenditures [Policy Text Block]	Exploration and evaluation expenditures Costs incurred before the Company has obtained the legal rights to explore an area are expensed as incurred. Exploration and evaluation expenditures include the costs of acquiring licenses and costs associated with exploration and evaluation activity. Option payments are considered acquisition costs provided that the Company has the intention of exercising the underlying option. Property option agreements are exercisable entirely at the option of the optionee. Therefore, option payments (or recoveries) are recorded when payment is made (or received) and are not accrued. Exploration and evaluation expenditures are capitalized. The Company capitalizes costs to specific blocks of claims or areas of geological interest. Government tax credits received are recorded as a reduction to the cumulative costs incurred and capitalized on the related property. Exploration and evaluation assets are tested for impairment if facts or circumstances indicate that impairment exists. Examples of such facts and circumstances are as follows: - the period for which the Company has the right to explore in the specific area has expired during the period or will expire in the near future, and is not expected to be renewed; - substantive expenditure on further exploration for and evaluation of mineral resources in the specific area is neither budgeted nor planned; - exploration for and evaluation of mineral resources in the specific area have not led to the discovery of commercially viable quantities of mineral resources and the entity has decided to discontinue such activities in the specific area; and - sufficient data exist to indicate that, although a development in the specific area is likely to proceed, the carrying amount of the exploration and evaluation asset is unlikely to be recovered in full from successful development or by sale. After technical feasibility and commercial viability of extracting a mineral resource are demonstrable, the Company stops capitalizing expenditures for the applicable block of claims or geological area of interest and tests the asset for impairment. The capitalized balance, net of any impairment recognized, is then reclassified to either tangible or intangible mine development assets according to the nature of the asset.
Share-based payments [Policy Text Block]	Share-based payments The Company operates an employee stock option plan. Share-based payments to employees are measured at the fair value of the instruments issued and amortized over the vesting periods. Share-based payments to non-employees are measured at the fair value of goods or services received or the fair value of the equity instruments issued, if it is determined the fair value of the goods or services cannot be reliably measured, and are recorded at the date the goods or services are received. The corresponding amount is recorded to the share-based payment reserve. The fair value of options is determined using the Black–Scholes option pricing model which incorporates all market vesting conditions. The number of shares and options expected to vest is reviewed and adjusted at the end of each reporting period such that the amount recognized for services received as consideration for the equity instruments granted shall be based on the number of equity instruments that eventually vest.
Loss per share [Policy Text Block]	Loss per share Basic loss per share is calculated by dividing the loss attributable to common shareholders by the weighted average number of common shares outstanding in the period. For all periods presented, the loss attributable to common shareholders equals the reported loss attributable to owners of the Company. Diluted loss per share is calculated by the treasury stock method. Under the treasury stock method, the weighted average number of common shares outstanding for the calculation of diluted loss per share assumes that the proceeds to be received on the exercise of dilutive share options and warrants are used to repurchase common shares at the average market price during the period.
Recognition of Financial Instruments [Policy Text Block]	Recognition of Financial Instruments The Company recognizes a financial asset or financial liability on the statement of financial position when it becomes a party to the contractual provisions of the financial instrument. The Company classifies its financial instruments in the following categories: at fair value through profit and loss (“FVTPL”), at fair value through other comprehensive income (loss) (“FVTOCI”) or at amortized cost. The Company determines the classification of financial assets at initial recognition. The classification of debt instruments is driven by the Company’s business model for managing the financial assets and their contractual cash flow characteristics. Equity instruments that are held for trading are classified as FVTPL. For other equity instruments, on the day of acquisition the Company can make an irrevocable election (on an instrument-by-instrument basis) to designate them as at FVTOCI. Financial liabilities are measured at amortized cost, unless they are required to be measured at FVTPL (such as instruments held for trading or derivatives) or if the Company has opted to measure them at FVTPL.
Financial assets at FVTOCI [Policy Text Block]	Financial assets at FVTOCI Investments in equity instruments designated at FVTOCI are initially recognized at fair value plus transaction costs. Subsequently they are measured at fair value, with both realized and unrealized gains and losses recognized in other comprehensive income (loss) in the period in which they arise.
Financial assets and liabilities at amortized cost [Policy Text Block]	Financial assets and liabilities at amortized cost Financial assets and liabilities at amortized cost are initially recognized at fair value plus or minus transaction costs, respectively, and subsequently carried at amortized cost less any impairment.
Financial assets and liabilities at FVTPL [Policy Text Block]	Financial assets and liabilities at FVTPL Financial assets and liabilities carried at FVTPL are initially recorded at fair value and transaction costs are expensed in profit or loss. Realized and unrealized gains and losses arising from changes in the fair value of the financial assets and liabilities held at FVTPL are included in profit or loss in the period in which they arise. Where management has opted to recognize a financial liability at FVTPL, any changes associated with the Company’s own credit risk will be recognized in other comprehensive income (loss).
Impairment of financial assets at amortized cost [Policy Text Block]	Impairment of financial assets at amortized cost The Company recognizes a loss allowance for expected credit losses on financial assets that are measured at amortized cost. At each reporting date, the Company measures the loss allowance for the financial asset at an amount equal to the lifetime expected credit losses if the credit risk on the financial asset has increased significantly since initial recognition. If at the reporting date, the financial asset has not increased significantly since initial recognition, the Company measures the loss allowance for the financial asset at an amount equal to the twelve month expected credit losses. The Company shall recognize in the profit or loss, as an impairment gain or loss, the amount of expected credit losses (or reversal) that is required to adjust the loss allowance at the reporting date to the amount that is required to be recognized.
Derecognition of financial assets and liabilities [Policy Text Block]	Derecognition of financial assets and liabilities The Company derecognizes financial assets only when the contractual rights to cash flows from the financial assets expire, or when it transfers the financial assets and substantially all of the associated risks and rewards of ownership to another entity. Gains and losses on derecognition are generally recognized in profit or loss in the period in which they arise. However, gains and losses on derecognition of financial assets designated as FVTOCI are recorded in other comprehensive income (loss) in the period in which they arise. Cumulative gains and losses on derecognized financial assets designated as FVTOCI are reclassified from accumulated other comprehensive income (loss) to deficit. The Company derecognizes financial liabilities only when its obligations under the financial liabilities are discharged, cancelled or expired. Generally, the difference between the carrying amount of the financial liability derecognized and the consideration paid and payable, including any non-cash assets transferred or liabilities assumed, is recognized in profit or loss.
Impairment of assets [Policy Text Block]	Impairment of assets The carrying amount of the Company’s assets (which include equipment and exploration and evaluation assets) is reviewed at each reporting date to determine whether there is any indication of impairment. If such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss. An impairment loss is recognized whenever the carrying amount of an asset or its cash generating unit exceeds its recoverable amount. Impairment losses are recognized in the statement of comprehensive income (loss). The recoverable amount of assets is the greater of an asset’s fair value less cost to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects the current market assessments of the time value of money and the risks specific to the asset. For an asset that does not generate cash inflows largely independent of those from other assets, the recoverable amount is determined for the cash-generating unit to which the asset belongs. An impairment loss is only reversed if there is an indication that the impairment loss may no longer exist and there has been a change in the estimates used to determine the recoverable amount. Any reversal of impairment cannot increase the carrying value of the asset to an amount higher than the carrying amount that would have been determined had no impairment loss been recognized in previous years. Assets that have an indefinite useful life are not subject to amortization and are tested annually for impairment.
Income taxes [Policy Text Block]	Income taxes Current income tax: Current income tax relating to items recognized directly in other comprehensive income or equity is recognized in other comprehensive income or equity and not in profit or loss. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate. Deferred income tax: The carrying amount of deferred income tax assets is reviewed at the end of each reporting period and recognized only to the extent that it is probable that sufficient taxable profit will be available to allow all or part of the deferred income tax asset to be utilized. Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply to the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. Deferred income tax assets and deferred income tax liabilities are offset, if a legally enforceable right exists to set off current tax assets against current income tax liabilities and the deferred income taxes relate to the same taxable entity and the same taxation authority. Flow-through shares: To the extent that the Company has suitable unrecognized deductible temporary differences, an offsetting recovery of deferred income taxes would be recorded.
Restoration and environmental obligations [Policy Text Block]	Restoration and environmental obligations The Company recognizes liabilities for statutory, contractual, constructive or legal obligations associated with the retirement of long-term assets, when those obligations result from the acquisition, construction, development or normal operation of the assets. The net present value of future restoration cost estimates arising from the decommissioning of plant and other site preparation work is capitalized to the related asset along with a corresponding increase in the restoration provision in the period incurred. Discount rates using a pre-tax rate that reflect the time value of money are used to calculate the net present value. The Company’s estimates of restoration costs could change as a result of changes in regulatory requirements, discount rates and assumptions regarding the amount and timing of the future expenditures. These changes are recorded directly to the related asset with a corresponding entry to the restoration provision. The Company’s estimates are reviewed annually for changes in regulatory requirements, discount rates, effects of inflation and changes in estimates. Changes in the net present value, excluding changes in the Company’s estimates of restoration costs, are charged to the statement of comprehensive loss for the period. The net present value of restoration costs arising from subsequent site damage that is incurred on an ongoing basis during production are charged to the statement of comprehensive loss in the period incurred. The costs of restoration projects that were included in the provision are recorded against the provision as incurred. The costs to prevent and control environmental impacts at specific properties are capitalized in accordance with the Company’s accounting policy for exploration and evaluation assets. At December 31, 2018 and 2017, the Company had no material restoration and environmental obligations.
Equipment [Policy Text Block]	Equipment Equipment is stated at historical cost less accumulated depreciation and accumulated impairment losses. 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 of the item can be measured reliably. The carrying amount of the replaced part is derecognized. All other repairs and maintenance are charged to the statement of comprehensive income (loss) during the financial period in which they are incurred. Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognized in the statement of comprehensive income (loss). Amortization is calculated on a declining balance method to write off the cost of the assets to their residual values over their estimated useful lives. The amortization rates applicable to each category of equipment are as follows: Class of equipment Amortization rate Motor vehicles 30% declining balance Computer equipment 30% declining balance Exploration and office equipment 20% declining balance
