Significant Accounting Policies [Text Block]	2. SIGNIFICANT ACCOUNTING POLICIES These condensed interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions to Form 10 10 X Securities Exchange Act of 1934 not May 31, 2019 10 August 31, 2019 three three August 31, 2019 not may May 31, 2020. 2019 not The preparation of these condensed interim consolidated financial statements in conformity with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of these condensed interim consolidated financial statements, and the reported amounts of revenues and expenses during the period. These judgments, estimates and assumptions are continuously evaluated and are based on management’s experience and knowledge of the relevant facts and circumstances. While management believes the estimates to be reasonable, actual results could differ from those estimates and could impact future results of operations and cash flows. Basis of consolidation These condensed interim 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 Nevada (a Nevada corporation), 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. Loss per share Basic loss per share is calculated using the weighted average number of common shares outstanding during the period. 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 period. 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 period ended August 31, 2019, 11,115,000 2018 9,861,900 not

New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	3. ADOPTION OF NEW ACCOUNTING STANDARDS AND AMENDMENTS Accounting Standrads Update: No. 2016 02 842 842 Effective June 1, 2019, Topic 842 a) The Company’s accounting policy under Topic 842 Definition of a lease At inception of a contract, the Company assesses whether a contract is, or contains, a lease based on whether the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Company has elected to apply the practical expedient to grandfather the lease definition for existing contracts on transition. It applied the definition of a lease under Topic 842 June 1, 2019. The Company has also elected to apply the practical expedient to account for each lease component and any non-lease components as a single lease component. As a lessee The Company leases its head office space, based on lease agreement having a fixed duration until January 30, 2023 August 31, 2020. 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, based on the initial amount of the lease liability. The assets are depreciated to the earlier of the end of the useful life of the right-of-use asset or the lease term using the straight-line method as this most closely reflects the expected pattern of consumption of the future economic benefits. The lease term includes periods covered by an option to extend if the Company is reasonably certain to exercise that option. In addition, the right-of-use asset is periodically 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 The ongoing lease liability is measured at amortized cost using the effective interest method. It is measured when there is a change in future lease payments, if there is a change in the Company’s estimate of the amount expected to be payable under a residual value guarantee, or if the Company changes its assessment of whether it will exercise a purchase, extension or termination option. When the lease liability is remeasured in this way a corresponding adjustment is made to the carrying amount of the right-of-use asset or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero. b) Impact of transition to Topic 842 Effective June 1, 2019, Topic 842 August 31, 2018 not June 1, 2019. August 31, 2018 On initial application, the Company has elected to record right-of-use assets based on the corresponding lease receivables and/or lease liabilities. Lease receivables and liabilities have been measured by discounting future lease payments at the incremental borrowing rate at June 1, 2019. 10% Topic 842 three eight The Company has elected to apply the practical expedient to account for leases for which the lease term ends within 12 The Company has also elected to apply the practical expedient for excluding the initial direct costs for the measurement of right-of-use assets at the date of initial application, as well as for using hindsight in determining the lease term where the contract contains options to extend or terminate the lease. The application of Topic 842 June 1, 2019 June 1, 2019 prior to adoption of Topic 842 – Lease Adjustments June 1, 2019 after adoption of Topic 842 – Lease Non-current assets: Right-of-use assets $ - $ 88,957 $ 88,957 Non-current liabilities Lease liabilities $ - $ 88,957 $ 88,957

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	These condensed interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions to Form 10 10 X Securities Exchange Act of 1934 not May 31, 2019 10 August 31, 2019 three three August 31, 2019 not may May 31, 2020. 2019 not The preparation of these condensed interim consolidated financial statements in conformity with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of these condensed interim consolidated financial statements, and the reported amounts of revenues and expenses during the period. These judgments, estimates and assumptions are continuously evaluated and are based on management’s experience and knowledge of the relevant facts and circumstances. While management believes the estimates to be reasonable, actual results could differ from those estimates and could impact future results of operations and cash flows.
Consolidation, Policy [Policy Text Block]	Basis of consolidation These condensed interim 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 Nevada (a Nevada corporation), 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.
Earnings Per Share, Policy [Policy Text Block]	Loss per share Basic loss per share is calculated using the weighted average number of common shares outstanding during the period. 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 period. 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 period ended August 31, 2019, 11,115,000 2018 9,861,900 not

[1]	The Company's North Bullfrog project consists of certain leased patented lode mining claims and federal unpatented mining claims owned 100% by the Company.
[2]	Pursuant to a purchase agreement made effective June 9, 2017 between Corvus Nevada and Goldcorp USA, Inc. ("Goldcorp USA"), Corvus Nevada has acquired 100% of the Mother Lode property (the "Mother Lode Property"). In addition, Corvus Nevada staked two additional adjacent claim blocks to the Mother Lode Property. In connection with the acquisition, the Company issued 1,000,000 common shares at a price of $0.81 per common share to Goldcorp USA (note 5). The Mother Lode Property is subject to an NSR in favour of Goldcorp USA. The NSR pays 1% from production at the Mother Lode Property when the price of gold is less than USD 1,400 per ounce and an additional 1% NSR for a total of 2% NSR when gold price is greater than or equal to USD 1,400 per ounce.
[3]	On June 7, 2019, the Company completed the sale of the royalties where four non-core Alaskan royalty interest owned by Corvus was sold to EMX Royalty Corporation ("EMX") for a purchase price of $350,000. In connection with the Alaskan royalty package sale, the Company incurred $31,463 in legal fees, resulting in a total cost recovery for the Alaska Royalty Interest of $318,537. The general terms of the Alaskan royalty package sale include: - Chisna project 1% NSR - LMS project 3% NSR - Goodpaster District 1% NSR - West Pogo project 2% NSR. The Company has retained a 1% NSR in the West Pogo project which is immediately west of the operating Pogo mine in the Goodpaster District of Alaska.
