Notes to Financial Statements
Nature of Operations [Text Block]	1. NATURE AND CONTINUANCE OF OPERATIONS On August 25, 2010, The Company was incorporated on April 13, 2010 Business Corporations Act (British Columbia) June 1, 2006. The Company is engaged in the business of acquiring, exploring and evaluating mineral properties, and either joint venturing or developing these properties further or disposing of them when the evaluation is completed. At November 30, 2016, The business of mining and exploration involves a high degree of risk and there can be no assurance that current exploration programs will result in profitable mining operations. The Company has no source of revenue, and has significant cash requirements to meet its administrative overhead and maintain its mineral property interests. The recoverability of amounts shown for mineral properties is dependent on several factors. These include the discovery of economically recoverable reserves, the ability of the Company to obtain the necessary financing to complete the development of these properties, and future profitable production or proceeds from disposition of mineral properties. The carrying value of the Company’s mineral properties does not reflect current or future values. These condensed interim consolidated financial statements have been prepared on a going concern basis, which presume the realization of assets and discharge of liabilities in the normal course of business for the foreseeable future. In assessing whether the going concern assumption is appropriate, management takes into account all available information about the future within one The Company has sustained losses from operations, has negative cash flows, and has an ongoing requirement for capital investment to explore its mineral properties. As at November 30, 2016, $4,870,893 $4,742,321 May 31, 2016. July 15, 2016, 2,550,000 $1.02 $2,601,000. 12 The Company expects that it will need to raise substantial additional capital to accomplish its business plan over the next several years. There is no assurance that additional capital or other types of financing will be available if needed or that these financings will be on terms at least as favourable to the Company as those previously obtained, or at all. Should such financing not be available in that time-frame, the Company will be required to reduce its activities and will not be able to carry out all of its presently planned exploration and development activities on its currently anticipated scheduling. These condensed interim consolidated financial statements do not include any adjustments to the amounts and classification of assets and liabilities that might be necessary should the Company be unable to continue in business.

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 1934, May 31, 2016 10 November 30, 2016 six six November 30, 2016 may May 31, 2017. 2016 The preparation of financial statements in conformity with US 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) and SoN Land and Water LLC (“SoN”) (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, 2016, 8,896,900 (2015 8,226,334)

Significant Accounting Policies (Policies)	6 Months Ended

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 1934, May 31, 2016 10 November 30, 2016 six six November 30, 2016 may May 31, 2017. 2016 The preparation of financial statements in conformity with US 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) and SoN Land and Water LLC (“SoN”) (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. For the period ended November 30, 2016, 8,896,900 (2015 8,226,334)
