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 8 03 X Securities Exchange Act of 1934 not May 31, 2020 10 November 30, 2020 six six November 30, 2020 not may May 31, 2021. 2020 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 November 30, 2020, 2019 not

Accounting Policies [Abstract]
Basis of Accounting, 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 November 30, 2020, 2019 not

Anti-Dilution: Pursuant to an amended agreement agreed to by the lessors in March 2015, all future payments will be satisfied by the delivery of an additional ½ common shares of the Company for each of the ITH common shares due per the original agreement (25,000 common shares of the Company) annually. Work Commitments: USD 100,000 per year for the first three years (incurred), USD 200,000 per year for the years four to six (incurred), USD 300,000 for the years seven to ten (incurred) and USD 300,000 for the years 11 – 20 (incurred). Excess expenditures in any year may be carried forward. If Corvus Nevada does not incur the required expenditures in year one, the deficiency is required to be paid to the lessors. Retained Royalty: Corvus Nevada will pay the lessors a NSR royalty of 2% if the average gold price is USD 400 per ounce or less, 3% if the average gold price is between USD 401 and USD 500 per ounce and 4% if the average gold price is greater than USD 500 per ounce. 10 (2) Pursuant to a mining lease and option to purchase made effective March 1, 2011 between Corvus Nevada and an arm’s length individual, Corvus Nevada has leased, and has the option to purchase, two patented mineral claims which form part of the North Bullfrog project holdings. The lease is for an initial term of ten years, subject to extension for an additional ten years (provided advance minimum royalties are timely paid), and for so long thereafter as mining activities continue on the claims. The lessee is required to pay advance minimum royalty payments (recoupable from production royalties, but not applicable to the purchase price if the option to purchase is exercised) of USD 30,000 (paid to March 1, 2020), adjusted for inflation. The lessor is entitled to receive a 2% NSR royalty on all production. The lessee may purchase the NSR royalty for USD 1,000,000 per 1%. If the lessee purchases the entire NSR royalty (USD 2,000,000) the lessee will also acquire all interest of the lessor in the subject property. (3) Pursuant to a purchase agreement made effective March 28, 2013, Corvus Nevada agreed to purchase the surface rights of five patented mining claims owned by two arm’s length individuals for USD 160,000 paid on closing ( March 28, 2013). The terms include payment by Corvus Nevada of a fee of USD 0.02 per ton of overburden to be stored on the property, subject to payment for a minimum of 12 million short tons. The minimum tonnage fee (USD 240,000) bears interest at 4.77% per annum from closing and is evidenced by a promissory note due on the sooner of the commencing of use of the property for waste materials storage or December 31, 2015 (balance paid December 17, 2015). As a result, the Company recorded $406,240 (USD 400,000) in acquisition costs with $157,408 paid in cash and the remaining $248,832 (USD 240,000) in promissory note payable during the year ended May 31, 2013. (4) In December 2013, SoN completed the purchase of a parcel of land approximately 30 kilometres north of the North Bullfrog project which carries with it 1,600 acre feet of irrigation water rights. The cost of the land and associated water rights was cash payment of $1,100,118 (USD 1,034,626). (5) On March 30, 2015, Lunar Landing, LLC signed a lease agreement with Corvus Nevada to lease private property containing the three patented Sunflower claims to Corvus Nevada, which are adjacent to the Yellow Rose claims leased in 2014. The term of the lease is three years with provision to extend the lease for an additional seven years, and an advance minimum royalty payment of USD 5,000 per year with USD 5,000 paid upon signing (paid to March 2020). The lease includes a 4% NSR royalty on production, with an option to purchase the royalty for USD 500,000 per 1% or USD 2,000,000 for the entire 4% royalty. The lease also includes the option to purchase the property for USD 300,000.
[2]	Mother Lode Property, Nevada 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. 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]	Alaskan Royalty Interest, Alaska On June 7, 2019, the Company completed the sale of the royalties where four non-core Alaskan royalty interests owned by Corvus were 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.
