[1]	Pursuant to a mining lease and option to purchase agreement made effective December 1, 2007 between Corvus Nevada and a group of arm’s length limited partnerships, Corvus Nevada has leased (and has the option to purchase) patented mining claims referred to as the “Mayflower” claims which form part of the North Bullfrog project. The terms of the lease/option are as follows: - Terms: Initial term of five years, commencing December 1, 2007, with the option to extend the lease for an additional five years. Pursuant to an extension agreement dated January 15, 2016 and fully executed and effective as of November 22, 2017, the parties agreed to extend the lease and option granted for an additional ten years with the same lease payment terms. - Lease Payments: Corvus Nevada will pay USD 10,000 and deliver 50,000 common shares of ITH annually (subject to the anti-dilution noted below). - Anti-Dilution: Pursuant to an amended agreement agreed to by the lessors in March 2015, the Company, 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. Pursuant to the amendment to the lease entered into on September 12, 2021, dated effective August 12, 2021, upon an acquisition transaction of Corvus, the share payment of 25,000 Common Shares of the Company and the share payment of 50,000 common shares of ITH is automatically converted into a cash payment equal to the share value equivalent using the price per share in the acquisition transaction for the shares of the Company and a price per share equal to the 10-day volume weighted average price of the ITH common shares calculated as of the end of the last trading day immediately preceding the payment due date. If an acquisition transaction of ITH occurs, the share payment of 50,000 common shares of ITH is automatically converted into a cash payment equal to the share value equivalent using the price per share in the acquisition transaction for the shares of ITH. - 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.

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. Earnings (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, 2021, 2020 not

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]	Earnings (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.

The terms of the lease/option are as follows: - Terms: Initial term of five years, commencing December 1, 2007, with the option to extend the lease for an additional five years. Pursuant to an extension agreement dated January 15, 2016 and fully executed and effective as of November 22, 2017, the parties agreed to extend the lease and option granted for an additional ten years with the same lease payment terms. - Lease Payments: Corvus Nevada will pay USD 10,000 and deliver 50,000 common shares of ITH annually (subject to the anti-dilution noted below). - Anti-Dilution: Pursuant to an amended agreement agreed to by the lessors in March 2015, the Company, 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. Pursuant to the amendment to the lease entered into on September 12, 2021, dated effective August 12, 2021, upon an acquisition transaction of Corvus, the share payment of 25,000 Common Shares of the Company and the share payment of 50,000 common shares of ITH is automatically converted into a cash payment equal to the share value equivalent using the price per share in the acquisition transaction for the shares of the Company and a price per share equal to the 10-day volume weighted average price of the ITH common shares calculated as of the end of the last trading day immediately preceding the payment due date. If an acquisition transaction of ITH occurs, the share payment of 50,000 common shares of ITH is automatically converted into a cash payment equal to the share value equivalent using the price per share in the acquisition transaction for the shares of ITH. - 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).

(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, 2021), adjusted for inflation.

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.

(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 2021).
