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. The lease will continue for as long thereafter as the property is in commercial production or, alternatively, for an additional three years if Corvus Nevada makes advance minimum royalty payments of USD 100,000 per year (which are recoupable against actual production royalties). Pursuant to an extension agreement agreed 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.

Significant Accounting Policies [Text Block]	2. SIGNIFICANT ACCOUNTING POLICIES Basis of presentation These unaudited condensed consolidated interim 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, 2017 10 November 30, 2017 six six November 30, 2017 not may May 31, 2018. 2017 not The preparation of 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 the 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 unaudited 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. 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, 2017, 9,861,900 2016 8,896,900 not Recent accounting pronouncements The Company continually assesses any new accounting pronouncements to determine their applicability. When it is determined that a new accounting pronouncement affects the Company's financial reporting, the Company undertakes a study to determine the consequences of the change to its consolidated financial statements and assures that there are proper controls in place to ascertain that the Company’s consolidated financial statements properly reflect the change.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of presentation These unaudited condensed consolidated interim 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, 2017 10 November 30, 2017 six six November 30, 2017 not may May 31, 2018. 2017 not The preparation of 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 the 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 unaudited 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. 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, 2017, 9,861,900 2016 8,896,900 not
New Accounting Pronouncements, Policy [Policy Text Block]	Recent accounting pronouncements The Company continually assesses any new accounting pronouncements to determine their applicability. When it is determined that a new accounting pronouncement affects the Company's financial reporting, the Company undertakes a study to determine the consequences of the change to its consolidated financial statements and assures that there are proper controls in place to ascertain that the Company’s consolidated financial statements properly reflect the change.

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. The lease will continue for as long thereafter as the property is in commercial production or, alternatively, for an additional three years if Corvus Nevada makes advance minimum royalty payments of USD 100,000 per year (which are recoupable against actual production royalties). Pursuant to an extension agreement agreed 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: USD 5,000 (paid) and 25,000 common shares of ITH (delivered) following regulatory acceptance of the transaction; and an additional USD 5,000 and 20,000 common shares on each of the first through fourth lease anniversaries (paid and issued).
