	Contango ORE, Inc. (“CORE” or the “Company”) is a Houston-based company that engages in the exploration in Alaska for gold and associated minerals through a joint venture company, Peak Gold, LLC. The Company was formed on September 1, 2010 as a Delaware corporation for the purpose of engaging in the exploration in the State of Alaska for gold ore and associated minerals.
	On November 29, 2010, Contango Mining Company ("Contango Mining"), a wholly owned subsidiary of Contango Oil & Gas Company (“Contango”), assigned the Original Properties (defined below) and certain other assets and liabilities to Contango. Contango contributed the Original Properties and $3.5 million of cash to the Company, in exchange for approximately 1.6 million shares of the Company’s common stock. The above transactions occurred between companies under common control and was accounted for as transactions between entities under common control, in accordance with Accounting Standards Codification ("ASC") 805, "Business Combinations" whereby the acquired assets and liabilities were recognized in the financial statements at their carrying amounts.
	The Original Properties contributed by Contango included: i) a 100% leasehold interest in approximately 675,000 acres (the "Tetlin Lease") from the Tetlin Village Council, the council formed by the governing body for the Native Village of Tetlin, an Alaska Native Tribe (the "Tetlin Village Council"); and ii) approximately 18,021 acres in unpatented mining claims from the state of Alaska for the exploration of gold ore and associated minerals (collectively, the “Original Properties”). If any of the Original Properties are placed into commercial production, the Company would be obligated to pay a 3.0% production royalty to Juneau Exploration, L.P. ("JEX"), a private company involved in the exploration and production of oil and natural gas. On September 29, 2014, JEX sold its 3.0% production royalty to Royal Gold, Inc. ("Royal Gold"). See Note 10 - Related Party Transactions. The Tetlin Lease is the Company's only material property.
	In September 2012, the Company and JEX entered into an Advisory Agreement in which JEX assisted the Company in acquiring 474 unpatented state of Alaska mining claims consisting of 71,896 acres for the exploration of gold and associated minerals in exchange for a 2.0% production royalty on properties acquired after July 1, 2012 (any such properties, the "Additional Properties"). If any of the Additional Properties are placed into commercial production, the Company would be obligated to pay JEX a 2.0% production royalty under the Advisory Agreement. On September 29, 2014, JEX sold its 2.0% production royalty to Royal Gold and the Company terminated its Advisory Agreement with JEX. See Note 10 - Related Party Transactions.
	On September 29, 2014, the Company entered into a Master Agreement (the “Master Agreement”) with Royal Gold, pursuant to which the parties agreed, subject to the satisfaction of various closing conditions, to form a joint venture to advance exploration and development of the Tetlin Properties (as defined below), prospective for gold and associated minerals (the “Transactions”). The Transactions closed on January 8, 2015 (the "Closing").
	In connection with the Closing, the Company contributed its Tetlin lease and state of Alaska mining claims near Tok, Alaska (the "Tetlin Properties"), together with other property, to Peak Gold, LLC, a newly formed limited liability company (the “Joint Venture Company”).  The Joint Venture Company is managed according to a Limited Liability Company Agreement between subsidiaries of Royal Gold and the Company    . At the Closing, Royal Gold made an initial investment of $5 million to fund exploration activity. The initial $5 million does not give Royal Gold an equity stake in the Joint Venture Company. Royal Gold will have the option to earn up to 40% economic interest in the joint venture by investing up to $30 million (inclusive of the initial $5 million investment) prior to October 2018. Therefore, at Closing, Royal Gold's percentage interest in the Joint Venture Company equaled 0% and the Company's percentage interest in the Joint Venture Company equaled 100%. The proceeds of Royal Gold’s investment will be used by the Joint Venture Company for additional exploration and development of the Tetlin Properties.
	The Company has completed five years of exploration efforts on the Tetlin Properties, which has resulted in the discovery of the Peak Zone mineralization within the Chief Danny prospect area on the Tetlin Lease. While no significant field exploration was conducted on the Tetlin Properties in 2014, the Joint Venture Company anticipates spending approximately $5 million in exploration work on the Tetlin Properties during the summer of 2015 and may expand the amount of exploration work in the late Summer of 2015, if drilling results warrant further work. Additionally, the Joint Venture Company acquired 59 new state of Alaska claims consisting of 9,439 acres in the Eagle claim area.

Basis of Presentation	. Basis of Presentation
	The accompanying unaudited consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), including instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete annual consolidated financial statements. In the opinion of management, all adjustments considered necessary for a fair statement of the consolidated financial statements have been included. All such adjustments are of a normal recurring nature. The consolidated financial statements should be read in conjunction with the audited financial statements and notes included in the Company’s Form 10-K for the fiscal year ended June 30, 2014, as amended. The results of operations for the three and nine months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the fiscal year ending June 30, 2015.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	The Company’s significant accounting policies are described below.
	Management Estimates. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	Cash Equivalents. Cash equivalents are considered to be highly liquid securities having an original maturity of 90 days or less at the date of acquisition.
	Restricted Cash. Cash equivalents which are restricted to be used in the development of Tetlins properties at the Joint Venture Company.
	Mineral Properties. The amount capitalized includes costs paid to acquire mineral property interests as well as the costs paid for federal and state of Alaska unpatented mining claims. Exploration costs are expensed as incurred. Development costs are expensed as incurred until the Company obtains proven and probable reserves within its commercially minable properties. Costs of abandoned projects are charged to earnings upon abandonment. Any properties determined to be impaired are written-down to their estimated fair value. The Company periodically evaluates whether events or changes in circumstances indicate that the carrying value of mineral property interests and any related property, plant and equipment may not be recoverable.
	Stock-Based Compensation. The Company applies the fair value method of accounting for stock-based compensation. Under this method, compensation cost is measured at the grant date based on the fair value of the award and is recognized over the award vesting period. The Company classifies the benefits of tax deductions in excess of the compensation cost recognized for the options (excess tax benefit) as financing cash flows. The fair value of each award is estimated as of the date of grant using the Black-Scholes option-pricing model.
	Income Taxes. The Company follows the liability method of accounting for income taxes under which deferred tax assets and liabilities are recognized for the future tax consequences of (i) temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements and (ii) operating loss and tax credit carry-forwards for tax purposes. Deferred tax assets are reduced by a valuation allowance when, based upon management’s estimates, it is more likely than not that a portion of the deferred tax assets will not be realized in a future period. The Company recognized a full valuation allowance as of March 31, 2015 and June 30, 2014 and has not recognized any tax provision or benefit for any of the periods. The Company reviews its tax positions quarterly for tax uncertainties. The Company did not have any uncertain tax positions as of March 31, 2015 or June 30, 2014.
	Consolidation of Joint Venture Company. The Company’s consolidated financial statements include the accounts of the Joint Venture Company, after elimination of all intercompany balances and transactions since it currently is wholly-owned by CORE Alaska, LLC, which is a wholly-owned subsidiary of the Company.
	Upon the formation of the Joint Venture Company, the Company was the only owner, and under the terms of the limited liability company agreement, was entitled to all of the Joint Venture Company’s assets and liabilities until Royal Gold invests more than $5 million in the Joint Venture Company. The Company therefore consolidated 100% of the Joint Venture Company’s net assets and results of operations.
	Recently Issued Accounting Pronouncements
	The Financial Accounting Standards Board (“FASB”) has issued Accounting Standards Update (“ASU”) No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The amendments in this ASU require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. The amendments are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years.
	The FASB has issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis, which is intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). The ASU focuses on the consolidation evaluation for reporting organizations (public and private companies and not-for-profit organizations) that are required to evaluate whether they should consolidate certain legal entities. The ASU will be effective for annual periods beginning after December 15, 2016; and for interim periods, within those fiscal years.
	The FASB has issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. This ASU eliminates from U.S. GAAP the concept of extraordinary items. Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, required that an entity separately classify, present, and disclose extraordinary events and transactions. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015.
	The Company has evaluated all other recent accounting pronouncements and believes that none of them will have a significant effect on the Company’s consolidated financial statements.

	If the Tetlin Lease is placed into commercial production, the Joint Venture Company would be obligated to pay a production royalty to the Tetlin Village Council, which varies from 2.0% to 5.0%, depending on the type of metal produced and the year of production. In June 2011, the Company paid the Tetlin Village Council $75,000 in exchange for reducing the production royalty payable to them by 0.25%. In July 2011, the Company paid the Tetlin Village Council $150,000 in exchange for further reducing the production royalty by 0.50%. These payments lowered the production royalty payable to a range of 1.25% to 4.25%, depending on the type of metal produced and the year of production. On or before July 15, 2020, the Tetlin Village Council has the option to increase their production royalty by (i) 0.25% by payment to the Joint Venture Company of $150,000, or (ii) 0.50% by payment to the Joint Venture Company of $300,000, or (iii) 0.75% by payment to the Joint Venture Company of $450,000. The Company has classified these payments as “Other Assets” on the consolidated balance sheet of the Company.

Formation of Joint Venture Company [Abstract]
Formation of Joint Venture Company [Table Text Block]	Formation of Joint Venture Company
	On January 8, 2015, the Company and Royal Gold, through their wholly-owned subsidiaries, consummated the Transactions contemplated under the Master Agreement, including the formation of a joint venture to advance exploration and development of the Company’s Tetlin Properties, for gold and associated minerals prospects.
	In connection with the Closing of the Transactions, the Company formed the Joint Venture Company. The Company contributed to the Joint Venture Company its Tetlin properties near Tok, Alaska, together with other property (the “Contributed Assets”) at an agreed value of $45.7 million (the “Contributed Assets Value”). At the Closing, the Company and Royal Gold, through their wholly-owned subsidiaries, entered into a Limited Liability Company Agreement for the Joint Venture Company (the “Joint Venture Company LLC Agreement”).
	As a condition to the Closing, the Company and the Tetlin Village Council entered into a Stability Agreement dated October 2, 2014, pursuant to which the Company and the Tetlin Village Council, among other things, acknowledged the continued validity of the Tetlin Lease and all its terms notwithstanding any future change in the status of the Tetlin Village Council or the property subject to the Tetlin Lease.
	At Closing, Royal Gold, as an initial contribution to the Joint Venture Company, contributed $5 million in restricted cash (the “Royal Gold Initial Contribution”) which is classified as a deferred option on our consolidated balance sheet. The Royal Gold Initial Contribution does not entitle Royal Gold to a percentage interest in the Joint Venture Company. Therefore, at Closing, Royal Gold’s percentage interest in the Joint Venture Company equaled 0% and the Company’s percentage interest in the Joint Venture Company equaled 100%. In addition, as part of the Closing, Royal Gold paid the Company $750,000 which was utilized to partially reimburse the Company for costs and expenses incurred in the Transactions and is included in revenue on our consolidated statements of operations.
	The Joint Venture Company's LLC Agreement provides Royal Gold with the right, but not the obligation, to earn a percentage interest in the Joint Venture Company (up to a maximum of 40%) by making additional contributions of capital to the Joint Venture Company in an aggregate amount equal to $30 million (inclusive of the Royal Gold Initial Contribution of $5 million) during the period beginning on the Closing and ending on October 31, 2018. If Royal Gold funds its full $30 million investment by October 31, 2018, it will receive a 40% interest in the Joint Venture Company, and the Company will retain a 60% interest in the Joint Venture Company.
	The proceeds of Royal Gold’s contributions to the Joint Venture Company (including the Royal Gold Initial Contribution) will be used by the Joint Venture Company to fund further exploration activities on the Tetlin Properties included in the Contributed Assets.
	Other than the Royal Gold's Initial Contribution, Royal Gold is not under any obligation to make capital contributions, to the Joint Venture Company by October 31, 2018 or thereafter. If Royal Gold does not make any additional capital contributions to the Joint Venture Company by October 31, 2018, and assuming there are no other new investors in the Joint Venture Company, the Company’s percentage interest in the Joint Venture Company would continue to be 100% and Royal Gold will be deemed to have resigned as a member of the Joint Venture Company effective as of October 31, 2018.
	Both the Company and Royal Gold will have the right to transfer each of their respective percentage interests in the Joint Venture Company to a third party, subject to certain terms and conditions set forth in the Joint Venture Company's LLC Agreement. If either member intends to transfer all or part of its percentage interest to a bona fide third party, the other member will have the right to require the transferring member to include in the intended transfer the other member’s proportionate share of its percentage interests at the same purchase price and terms and conditions. Once Royal Gold has earned a 40% interest in the Joint Venture Company, it will have the additional right to require the Company to sell up to 20% of the Company’s interest in the Joint Venture Company in a sale of Royal Gold’s entire 40% interest to a bona fide third party purchaser. If Royal Gold exercises this right, the Company will be obligated to sell the relevant portion of its percentage interest to a bona fide third party on the same terms and conditions as the interest being sold by Royal Gold.
	After October 31, 2018, or such earlier time as Royal Gold has earned a 40% interest in the Joint Venture Company, the members will contribute funds to approved programs and budgets in proportion to their respective percentage interests in the Joint Venture Company. If a member elects not to contribute to an approved program and budget or elects to contribute less than its proportionate interest, its percentage interest will be recalculated by dividing (i) the sum of (a) the value of its initial contribution plus (b) the total of all of its capital contributions plus (c) the amount of the capital contribution it elects to fund, by (ii) the sum of (a), (b) and (c) above for both members multiplied by 100.

	Mr. Brad Juneau, the Company's Chairman, President and Chief Executive Officer, is also the sole manager of JEX, a private company involved in the exploration and production of oil and natural gas. JEX was responsible for securing and negotiating the Tetlin Lease and assisting in obtaining the Original Properties and initially engaged Avalon to conduct mineral exploration activities on the Tetlin Lease. In agreeing to transfer its interests in the Original Properties to Contango Mining, a predecessor of the Company, JEX retained a 3.0% overriding royalty interest in the Original Properties transferred.
	In September 2012, the Company and JEX entered into an Advisory Agreement in which JEX provided assistance in acquiring additional properties in Alaska in exchange for a production royalty of 2.0% on properties acquired after July 1, 2012.
	On September 29, 2014, pursuant to a Royalty Purchase Agreement between JEX and Royal Gold (the “Royalty Purchase Agreement”), JEX sold its entire overriding royalty interest in the Original Properties and the Additional Properties to Royal Gold. On the same date, the Company terminated its Advisory Agreement with JEX.
	The Company currently subleases office space from JEX at 3700 Buffalo Speedway, Ste 925, Houston, TX 77098 for approximately $11,000 per quarter.

Stock Based Compensation	Stock-Based Compensation
	On September 15, 2010, the Company’s Board of Directors (the “Board”) adopted the Contango ORE, Inc. Equity Compensation Plan (the “2010 Plan”). Under the 2010 Plan, the Board may issue up to 1,000,000 shares of common stock and options to officers, directors, employees or consultants of the Company. Awards made under the 2010 Plan are subject to such restrictions, terms and conditions, including forfeitures, if any, as may be determined by the Board. As of March 31, 2015, there were 59,666 shares of unvested restricted common stock outstanding and options to purchase 445,000 shares of common stock outstanding issued under the 2010 Plan.
	Stock-based compensation expense for the periods reflected was as follows:
			Three Months Ended March 31,					Nine Months Ended March 31,
			2015			2014		2015		2014
	Stock-based compensation included in:
	Exploration expense (1)		$	136,429		$	69,625	$	241,663	296,571

	Total stock-based compensation expense		$	263,454		$	192,576	$	640,731	$	986,317
	(1)	Related to restricted stock and stock option awards to a former technical consultant.
	(2)	Related to restricted stock and stock option awards to the Company’s directors and employees.
	The amount of compensation expense recognized does not reflect compensation actually received by the individuals, but rather represents the amount recognized by the Company in accordance with GAAP.
	Restricted Stock. In November 2010, the Company granted 70,429 restricted shares of common stock to its officers and directors and an additional 23,477 restricted shares to a former technical consultant. All of the restricted stock from this grant was fully vested as of March 31, 2015.
	In December 2013, the Company's directors, executive officers and a former technical consultant were granted an aggregate of 95,000 shares of restricted stock. The restricted stock vests over two years, beginning with one-third vesting on the date of grant.
	In November 2014, the Company granted 27,000 restricted shares of common stock to its employees. The restricted stock vests over two years, beginning with one-third vesting on the date of grant. As of March 31, 2015 , there were 18,000 shares of such restricted stock that remained unvested. As of March 31, 2015, there were 21,666 shares of such restricted stock that remained unvested.
	In January 2015, the Company granted an aggregate of 30,000 restricted shares of common stock to two of its non-employee directors, 10,000 shares vested immediately and the remaining two-thirds will vest equally over two years. In addition, the Company granted 10,000 restricted shares of common stock to a former technical consultant which vested immediately. The Compensation Committee also elected to immediately vest all of the stock options and restricted stock previously issued to the former technical consultant. As of March 31, 2015, there were 20,000 shares of such restricted stock that remained unvested.
	As of March 31, 2015, the total compensation cost related to unvested awards not yet recognized was $311,710. The remaining costs will be recognized over the remaining vesting period of the awards.
	Stock Options. The option awards listed in the table below have been granted to directors, officers, employees and consultants of the Company:
	Option Awards
	Period Granted		Options Granted		Weighted Average Exercise Price	Vesting Period (7)
	September 2011 (1)		50,000		$13.13	Vests over two years, beginning with one-third on the grant date.

	(3) The Company granted 175,000 stock options to its directors and an additional 75,000 stock options to a former technical consultant for services performed during fiscal year 2013.
	(4) The Company granted 37,500 stock options to its employees for services performed during fiscal year 2013.
	(5) The Company granted 5,000 stock options to an employee of Avalon for services performed during fiscal year 2013.

	(7) If at any time there occurs a change of control, as defined in the 2010 Plan, any options that are unvested at that time will immediately vest. The Company's Compensation Committee has determined that the Transactions do not constitute a change of control under the 2010 Plan.
	The Company applies the fair value method to account for stock option expense. Under this method, cash flows from the exercise of stock options resulting from tax benefits in excess of recognized cumulative compensation cost (excess tax benefits) are classified as financing cash flows. See Note 3 – Summary of Significant Accounting Policies. All employee stock option grants are expensed over the stock option’s vesting period based on the fair value at the date the options are granted. The fair value of each option is estimated as of the date of grant using the Black-Scholes options-pricing model. As of March 31, 2015, the stock options had a weighted-average remaining life of approximately 3 years. The total compensation cost related to unvested options not yet recognized as of March 31, 2015 was $10,348.
	A summary of the status of stock options granted under the 2010 Plan as of March 31, 2015 and changes during the nine months then ended, is presented in the table below:

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies
	Tetlin Lease. The Tetlin Lease has a ten year term beginning July 2008 with an option to renew for an additional ten years, or so long as the Joint Venture Company initiates and continues to conduct mining operations on the Tetlin Lease. Originally, the Tetlin Lease allowed the Joint Venture Company to only renew 50% of the acreage, but in December 2012, the Joint Venture Company paid the Tetlin Village Council $200,000 in exchange for removing this 50% restriction. The Joint Venture Company is now able to renew all 675,000 acres in 2018. The Tetlin Lease is the Company's only material property.
	Pursuant to the terms of the Tetlin Lease, the Joint Venture Company is required to spend $350,000 per year in exploration costs until July 15, 2018. However, because exploration funds spent in any year in excess of $350,000 are credited toward future years’ exploration cost requirements, the Joint Venture Company’s exploration expenditures to date have already satisfied this work commitment requirement for the full lease term, through 2018. Additionally, should the Joint Venture Company derive revenues from the properties covered under the Tetlin Lease, the Joint Venture Company is required to pay the Tetlin Village Council a production royalty ranging from 2.0% to 5.0%, depending on the type of metal produced and the year of production. As of March 31, 2015, the Joint Venture Company has paid the Tetlin Village Council an aggregate of $225,000 in exchange for reducing the production royalty payable to it by 0.75%. These payments lowered the production royalty to a range of 1.25% to 4.25%. On or before July 15, 2020, the Tetlin Village Council has the option to increase its production royalty by (i) 0.25% by payment to the Joint Venture Company of $150,000 (ii) 0.50% by payment to the Joint Venture Company of $300,000, or (iii) 0.75% by payment to the Joint Venture Company of $450,000. Until such time as production royalties begin, the Joint Venture Company pays the Tetlin Village Council an advance minimum royalty each year. On July 15, 2012, the advance minimum royalty increased from $50,000 to $75,000 per year, and after July 15, 2013, the advance minimum royalty is escalated by an inflation adjustment. As of March 31, 2015, the Joint Venture Company had prepaid $40,000 of the $75,000 advance minimum royalty that is due to the Tetlin Village Council on July 15, 2015.
	Gold Exploration. The Joint Venture Company’s Triple Z, TOK/Tetlin, Eagle, Bush and ADC 2 claims are all located on state of Alaska lands. The annual claim rentals on these projects total 94,815 per year, and are due and payable in full by November 30 of each year. The Joint Venture Company has met the annual labor requirements for the state of Alaska acreage for the next four years, which is the maximum time allowable by Alaska law.
	Royal Gold Royalties. Pursuant to the Royalty Purchase Agreement, the Joint Venture Company will pay Royal Gold an overriding royalty of 3.0% should the Joint Venture Company derive revenues from any of the Original Properties and an overriding royalty of 2.0% should the Joint Venture Company derive revenues from any of the Additional Properties.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Mar. 31, 2015
Accounting Policies [Abstract]
Management Estimates	Management Estimates. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash Equivalents	Cash Equivalents. Cash equivalents are considered to be highly liquid securities having an original maturity of 90 days or less at the date of acquisition.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	Restricted Cash. Cash equivalents which are restricted to be used in the development of Tetlins properties at the Joint Venture Company.
Capitalized Costs	Mineral Properties. The amount capitalized includes costs paid to acquire mineral property interests as well as the costs paid for federal and state of Alaska unpatented mining claims. Exploration costs are expensed as incurred. Development costs are expensed as incurred until the Company obtains proven and probable reserves within its commercially minable properties. Costs of abandoned projects are charged to earnings upon abandonment. Any properties determined to be impaired are written-down to their estimated fair value. The Company periodically evaluates whether events or changes in circumstances indicate that the carrying value of mineral property interests and any related property, plant and equipment may not be recoverable.
Stock-Based Compensation	Stock-Based Compensation. The Company applies the fair value method of accounting for stock-based compensation. Under this method, compensation cost is measured at the grant date based on the fair value of the award and is recognized over the award vesting period. The Company classifies the benefits of tax deductions in excess of the compensation cost recognized for the options (excess tax benefit) as financing cash flows. The fair value of each award is estimated as of the date of grant using the Black-Scholes option-pricing model.
Income Taxes	Income Taxes. The Company follows the liability method of accounting for income taxes under which deferred tax assets and liabilities are recognized for the future tax consequences of (i) temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements and (ii) operating loss and tax credit carry-forwards for tax purposes. Deferred tax assets are reduced by a valuation allowance when, based upon management’s estimates, it is more likely than not that a portion of the deferred tax assets will not be realized in a future period. The Company recognized a full valuation allowance as of March 31, 2015 and June 30, 2014 and has not recognized any tax provision or benefit for any of the periods. The Company reviews its tax positions quarterly for tax uncertainties. The Company did not have any uncertain tax positions as of March 31, 2015 or June 30, 2014.
Consolidation, Subsidiaries or Other Investments, Consolidated Entities, Policy [Policy Text Block]	Consolidation of Joint Venture Company. The Company’s consolidated financial statements include the accounts of the Joint Venture Company, after elimination of all intercompany balances and transactions since it currently is wholly-owned by CORE Alaska, LLC, which is a wholly-owned subsidiary of the Company.
	Upon the formation of the Joint Venture Company, the Company was the only owner, and under the terms of the limited liability company agreement, was entitled to all of the Joint Venture Company’s assets and liabilities until Royal Gold invests more than $5 million in the Joint Venture Company. The Company therefore consolidated 100% of the Joint Venture Company’s net assets and results of operations.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements
	The Financial Accounting Standards Board (“FASB”) has issued Accounting Standards Update (“ASU”) No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The amendments in this ASU require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. The amendments are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years.
	The FASB has issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis, which is intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). The ASU focuses on the consolidation evaluation for reporting organizations (public and private companies and not-for-profit organizations) that are required to evaluate whether they should consolidate certain legal entities. The ASU will be effective for annual periods beginning after December 15, 2016; and for interim periods, within those fiscal years.
	The FASB has issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. This ASU eliminates from U.S. GAAP the concept of extraordinary items. Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, required that an entity separately classify, present, and disclose extraordinary events and transactions. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015.
	The Company has evaluated all other recent accounting pronouncements and believes that none of them will have a significant effect on the Company’s consolidated financial statements.
