Notes to Financial Statements
Significant Accounting Policies [Text Block]	2. SIGNIFICANT ACCOUNTING POLICIES Basis of presentation These consolidated financial statements are presented in Canadian dollars and have been prepared in accordance with generally accepted accounting principles in the United States (“US GAAP”). Basis of consolidation These consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries (collectively, the “Group”), Corvus Gold (USA) Inc. (“Corvus USA”) (a Nevada corporation), Corvus Gold Nevada Inc. (“Corvus Nevada”) (a Nevada corporation), Raven Gold Alaska Inc. (“Raven Gold”) (an Alaska corporation), SoN Land and Water LLC (“SoN”) (a Nevada limited liability company) and Mother Lode Mining Company LLC (a Nevada limited liability company). All intercompany transactions and balances were eliminated upon consolidation. Significant judgments, estimates and assumptions The preparation of these financial statements in accordance with US GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of expenses during the reporting year. Actual outcomes could differ from these estimates. These financial statements include estimates which, by their nature, are uncertain. The impacts of such estimates are pervasive throughout the financial statements, and may Significant estimates Significant assumptions about the future and other sources of estimation uncertainty that management has made at the end of the reporting year, that could result in a material adjustment to the carrying amounts of assets and liabilities, in the event that actual results differ from assumptions made, relate to, but are not Significant judgments Critical accounting judgments are accounting policies that have been identified as being complex or involving subjective judgments or assessments. The Company made the following critical accounting judgments: · The determination of deferred tax assets and liabilities. · The analysis of resource calculations, drill results, laboratory work, etc., which can impact the Company’s assessment of impairments, and provisions, if any, for environmental rehabilitation and restorations. · The determination of functional currency. using the currency of the primary economic environment in which each of the parent company and its subsidiaries operates. · The assessment of the Company’s ability to continue as a going concern. Cash and cash equivalents Cash equivalents include highly liquid investments in term deposits that are readily convertible to known amounts of cash with original maturities of three three 30 no Foreign currency translation The presentation currency of the Company is the Canadian dollar. The functional currency of each of the parent company and its subsidiaries is measured using the currency of the primary economic environment in which that entity operates. The functional currency of Corvus USA, Corvus Nevada, Raven Gold, SoN, and Mother Lode Mining Company LLC is US dollars, and for the Company the functional currency is Canadian dollars. Transactions and balances Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the date of the transaction. Foreign currency monetary items are translated at the year-end exchange rate. Non-monetary items measured at historical cost continue to be carried at the exchange rate at the date of the transaction. Non-monetary items measured at fair value are reported at the exchange rate at the date when fair values were determined. Exchange differences arising on the translation of monetary items or on settlement of monetary items are recognized in profit or loss in the Statement of Operations and Comprehensive Loss in the year in which they arise. Exchange differences arising on the translation of non-monetary items are recognized in other comprehensive income (loss) in the Statement of Operations and Comprehensive Loss to the extent that gains and losses arising on those non-monetary items are also recognized in other comprehensive income (loss). Where the non-monetary gain or loss is recognized in profit or loss, the exchange component is also recognized in profit or loss. Parent and Subsidiary Companies The financial results and position of foreign operations whose functional currency is different from the presentation currency are translated as follows: · Assets and liabilities are translated at year-end exchange rates prevailing at that reporting date; and · Income and expenses are translated at monthly average exchange rates during the year. Exchange differences arising on translation of foreign operations are transferred directly to the Group’s exchange difference on translating foreign operations in the Statement of Operations and Comprehensive Loss and are reported as a separate component of shareholders’ equity titled “Cumulative Translation Differences”. These differences are recognized in profit or loss in the year in which the operation is disposed of. Property and equipment a) Recognition and measurement On initial recognition, property and equipment are valued at cost, being the purchase price and directly attributable costs of acquisition or construction required to bring the asset to the location and condition necessary to be capable of operating in the manner intended by the Company, including appropriate borrowing costs and the estimated present value of any future unavoidable costs of dismantling and removing items. Property and equipment is subsequently measured at cost less accumulated depreciation, less any accumulated impairment losses, with the exception of land which is not When parts of an item of property and equipment have different useful lives, they are accounted for as separate items (major components) of property and equipment. b) Subsequent costs The cost of replacing part of an item of property and equipment is recognized in the carrying amount of the item if it is probable that the future economic benefit embodied within the part will flow to the Company and its cost can be measured reliably. The carrying amount of the replaced part is derecognized. The costs of the day-to-day servicing of property and equipment are recognized in profit or loss as incurred. c) Major maintenance and repairs 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. All other repairs and maintenance expenditures are charged to profit or loss during the financial year in which they are incurred. d) Gains and losses Gains and losses on disposal of an item of property and equipment are determined by comparing the proceeds from disposal with the carrying amount, and are recognized net within other items in profit or loss. e) Depreciation Depreciation is recognized in profit or loss on a declining-balance basis at the following annual rates: Computer equipment - 30% Vehicles - 30% Tent - 20% Additions during the year are depreciated at one Depreciation methods, useful lives and residual values are reviewed at each financial year-end and adjusted if appropriate. Mineral properties and exploration and evaluation expenditures The Company’s mineral projects are currently in the exploration and evaluation phase. All direct costs related to the acquisition of mineral property interests are capitalized. Mineral property exploration costs are expensed as incurred. At such time that the Company determines that a mineral property can be economically developed, subsequent mineral property expenses will be capitalized during the development of such property. Impairment of long-lived assets The Company assesses long-lived assets for impairment or when facts and circumstances suggest that the carrying amount of an asset may not, not 50%. Asset retirement obligations The Company records a liability based on the best estimate of costs for site closure and reclamation activities that the Company is legally or contractually required to remediate at the time environmental disturbance occurs. The provision for closure and reclamation liabilities is estimated using expected cash flows based on engineering and environmental reports and accreted to full value over time through periodic charges to profit or loss. As at May 31, 2019, $419,286 309,000 2018 $366,641 283,000 Income taxes The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under the asset and liability method, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized if it is more likely than not not Share capital The proceeds from the exercise of stock options, warrants and escrow shares are recorded as share capital in the amount for which the option, warrant or escrow share enabled the holder to purchase a share in the Company. Commissions paid to agents, and other related share issuance costs, such as legal, auditing, and printing, on the issue of the Company’s shares are charged directly to share capital. Valuation of equity units issued in private placements The Company has adopted a residual value method with respect to the measurement of shares and warrants issued as private placement units. The residual value method first The fair value of the common shares issued in the private placements was determined to be the more easily measurable component and were valued at their fair value, as determined by the closing quoted bid price on the announcement date. The balance, if any, is allocated to the attached warrants. Any fair value attributed to the warrants is recorded as contributed surplus. Upon exercise of the warrants, the related fair value is reallocated to share capital. Earnings (loss) per share Basic loss per share is calculated using the weighted average number of common shares outstanding during the year. The Company uses the treasury stock method to compute the dilutive effect of options, warrants and similar instruments. Under this method, the dilutive effect on earnings (loss) per share is calculated presuming the exercise of outstanding options, warrants and similar instruments. It assumes that the proceeds of such exercise would be used to repurchase common shares at the average market price during the year. However, the calculation of diluted loss per share excludes the effects of various conversions and exercise of options and warrants that would be anti-dilutive. For the year ended May 31, 2019, 10,000,000 2018 9,861,900 not Stock-based compensation The Company follows the provisions of Financial Accounting Standards Board Accounting Standards Codification Section 718 Non-monetary transactions All non-monetary transactions are measured at the fair value of the asset surrendered or the asset received, whichever is more reliable, unless the transaction lacks commercial substance or the fair value cannot be reliably established. The commercial substance requirement is met when the future cash flows are expected to change significantly as a result of the transaction. When the fair value of a non-monetary transaction cannot be reliably measured, it is recorded at the carrying amount (after reduction, when appropriate, for impairment) of the asset given up adjusted by the fair value of any monetary consideration received or given. When the asset received or the consideration given up is shares in an actively traded market, the value of those shares will be considered fair value. Joint venture accounting Where the Company’s exploration and development activities are conducted with others, the accounts reflect only the Company’s proportionate interest in such activities.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of presentation These consolidated financial statements are presented in Canadian dollars and have been prepared in accordance with generally accepted accounting principles in the United States (“US GAAP”).
Consolidation, Policy [Policy Text Block]	Basis of consolidation These consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries (collectively, the “Group”), Corvus Gold (USA) Inc. (“Corvus USA”) (a Nevada corporation), Corvus Gold Nevada Inc. (“Corvus Nevada”) (a Nevada corporation), Raven Gold Alaska Inc. (“Raven Gold”) (an Alaska corporation), SoN Land and Water LLC (“SoN”) (a Nevada limited liability company) and Mother Lode Mining Company LLC (a Nevada limited liability company). All intercompany transactions and balances were eliminated upon consolidation.
Use of Estimates, Policy [Policy Text Block]	Significant judgments, estimates and assumptions The preparation of these financial statements in accordance with US GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of expenses during the reporting year. Actual outcomes could differ from these estimates. These financial statements include estimates which, by their nature, are uncertain. The impacts of such estimates are pervasive throughout the financial statements, and may Significant estimates Significant assumptions about the future and other sources of estimation uncertainty that management has made at the end of the reporting year, that could result in a material adjustment to the carrying amounts of assets and liabilities, in the event that actual results differ from assumptions made, relate to, but are not Significant judgments Critical accounting judgments are accounting policies that have been identified as being complex or involving subjective judgments or assessments. The Company made the following critical accounting judgments: · The determination of deferred tax assets and liabilities. · The analysis of resource calculations, drill results, laboratory work, etc., which can impact the Company’s assessment of impairments, and provisions, if any, for environmental rehabilitation and restorations. · The determination of functional currency. using the currency of the primary economic environment in which each of the parent company and its subsidiaries operates. · The assessment of the Company’s ability to continue as a going concern.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and cash equivalents Cash equivalents include highly liquid investments in term deposits that are readily convertible to known amounts of cash with original maturities of three three 30 no
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign currency translation The presentation currency of the Company is the Canadian dollar. The functional currency of each of the parent company and its subsidiaries is measured using the currency of the primary economic environment in which that entity operates. The functional currency of Corvus USA, Corvus Nevada, Raven Gold, SoN, and Mother Lode Mining Company LLC is US dollars, and for the Company the functional currency is Canadian dollars. Transactions and balances Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the date of the transaction. Foreign currency monetary items are translated at the year-end exchange rate. Non-monetary items measured at historical cost continue to be carried at the exchange rate at the date of the transaction. Non-monetary items measured at fair value are reported at the exchange rate at the date when fair values were determined. Exchange differences arising on the translation of monetary items or on settlement of monetary items are recognized in profit or loss in the Statement of Operations and Comprehensive Loss in the year in which they arise. Exchange differences arising on the translation of non-monetary items are recognized in other comprehensive income (loss) in the Statement of Operations and Comprehensive Loss to the extent that gains and losses arising on those non-monetary items are also recognized in other comprehensive income (loss). Where the non-monetary gain or loss is recognized in profit or loss, the exchange component is also recognized in profit or loss. Parent and Subsidiary Companies The financial results and position of foreign operations whose functional currency is different from the presentation currency are translated as follows: · Assets and liabilities are translated at year-end exchange rates prevailing at that reporting date; and · Income and expenses are translated at monthly average exchange rates during the year. Exchange differences arising on translation of foreign operations are transferred directly to the Group’s exchange difference on translating foreign operations in the Statement of Operations and Comprehensive Loss and are reported as a separate component of shareholders’ equity titled “Cumulative Translation Differences”. These differences are recognized in profit or loss in the year in which the operation is disposed of.
Property, Plant and Equipment, Policy [Policy Text Block]	Property and equipment a) Recognition and measurement On initial recognition, property and equipment are valued at cost, being the purchase price and directly attributable costs of acquisition or construction required to bring the asset to the location and condition necessary to be capable of operating in the manner intended by the Company, including appropriate borrowing costs and the estimated present value of any future unavoidable costs of dismantling and removing items. Property and equipment is subsequently measured at cost less accumulated depreciation, less any accumulated impairment losses, with the exception of land which is not When parts of an item of property and equipment have different useful lives, they are accounted for as separate items (major components) of property and equipment. b) Subsequent costs The cost of replacing part of an item of property and equipment is recognized in the carrying amount of the item if it is probable that the future economic benefit embodied within the part will flow to the Company and its cost can be measured reliably. The carrying amount of the replaced part is derecognized. The costs of the day-to-day servicing of property and equipment are recognized in profit or loss as incurred. c) Major maintenance and repairs 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. All other repairs and maintenance expenditures are charged to profit or loss during the financial year in which they are incurred. d) Gains and losses Gains and losses on disposal of an item of property and equipment are determined by comparing the proceeds from disposal with the carrying amount, and are recognized net within other items in profit or loss. e) Depreciation Depreciation is recognized in profit or loss on a declining-balance basis at the following annual rates: Computer equipment - 30% Vehicles - 30% Tent - 20% Additions during the year are depreciated at one Depreciation methods, useful lives and residual values are reviewed at each financial year-end and adjusted if appropriate.

All direct costs related to the acquisition of mineral property interests are capitalized. Mineral property exploration costs are expensed as incurred. At such time that the Company determines that a mineral property can be economically developed, subsequent mineral property expenses will be capitalized during the development of such property.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of long-lived assets The Company assesses long-lived assets for impairment or when facts and circumstances suggest that the carrying amount of an asset may not, not 50%.
Asset Retirement Obligation [Policy Text Block]	Asset retirement obligations The Company records a liability based on the best estimate of costs for site closure and reclamation activities that the Company is legally or contractually required to remediate at the time environmental disturbance occurs. The provision for closure and reclamation liabilities is estimated using expected cash flows based on engineering and environmental reports and accreted to full value over time through periodic charges to profit or loss. As at May 31, 2019, $419,286 309,000 2018 $366,641 283,000
Income Tax, Policy [Policy Text Block]	Income taxes The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under the asset and liability method, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized if it is more likely than not not
Share Capital [Policy Text Block]	Share capital The proceeds from the exercise of stock options, warrants and escrow shares are recorded as share capital in the amount for which the option, warrant or escrow share enabled the holder to purchase a share in the Company. Commissions paid to agents, and other related share issuance costs, such as legal, auditing, and printing, on the issue of the Company’s shares are charged directly to share capital.
Equity Method Investments Issuances, Policy [Policy Text Block]	Valuation of equity units issued in private placements The Company has adopted a residual value method with respect to the measurement of shares and warrants issued as private placement units. The residual value method first The fair value of the common shares issued in the private placements was determined to be the more easily measurable component and were valued at their fair value, as determined by the closing quoted bid price on the announcement date. The balance, if any, is allocated to the attached warrants. Any fair value attributed to the warrants is recorded as contributed surplus. Upon exercise of the warrants, the related fair value is reallocated to share capital.
Earnings Per Share, Policy [Policy Text Block]	Earnings (loss) per share Basic loss per share is calculated using the weighted average number of common shares outstanding during the year. The Company uses the treasury stock method to compute the dilutive effect of options, warrants and similar instruments. Under this method, the dilutive effect on earnings (loss) per share is calculated presuming the exercise of outstanding options, warrants and similar instruments. It assumes that the proceeds of such exercise would be used to repurchase common shares at the average market price during the year. However, the calculation of diluted loss per share excludes the effects of various conversions and exercise of options and warrants that would be anti-dilutive. For the year ended May 31, 2019, 10,000,000 2018 9,861,900 not
Share-based Payment Arrangement [Policy Text Block]	Stock-based compensation The Company follows the provisions of Financial Accounting Standards Board Accounting Standards Codification Section 718
Non-monetary Transactions [Policy Text Block]	Non-monetary transactions All non-monetary transactions are measured at the fair value of the asset surrendered or the asset received, whichever is more reliable, unless the transaction lacks commercial substance or the fair value cannot be reliably established. The commercial substance requirement is met when the future cash flows are expected to change significantly as a result of the transaction. When the fair value of a non-monetary transaction cannot be reliably measured, it is recorded at the carrying amount (after reduction, when appropriate, for impairment) of the asset given up adjusted by the fair value of any monetary consideration received or given. When the asset received or the consideration given up is shares in an actively traded market, the value of those shares will be considered fair value.
