Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	9. Sales Transaction with KG Mining On September 29, 2020, the Company, CORE Alaska and KG Mining, entered into entered into a Purchase Agreement (the “CORE Purchase Agreement”), pursuant to which CORE Alaska sold a 30.0% membership interest (the “CORE JV Interest”) in the Peak Gold JV, to KG Mining (the “CORE Transactions”). The CORE Transactions closed on September 30, 2020. In consideration for the CORE JV Interest, the Company received $32.4 million in cash and 809,744 shares of Common Stock. The 809,744 shares of Common Stock were acquired by KG Mining from Royal Gold, as part of the Royal Gold Transactions and were subsequently canceled by the Company. Of the $32.4 million cash consideration, $1.2 million constituted a reimbursement prepayment to the Company relating to its proportionate share of silver royalty payments that the Peak Gold JV may be obligated to pay to Royal Gold, with the understanding that KG Mining will bear the entire economic impact of those royalty payments due from the Peak Gold JV. Concurrently with the Purchase Agreement, KG Mining, in a separate transaction, acquired from Royal Gold (i) 100% of the equity of Royal Alaska, LLC , which held a 40.0% membership interest in the Peak Gold JV and (ii) 809,744 shares of Common Stock held by Royal Gold. After the consummation of the Kinross Transactions, CORE Alaska retains a 30.0% membership interest in the Peak Gold JV. KG Mining now holds a 70.0% membership interest in the Peak Gold JV and serves as the manager and operator of the Peak Gold JV. KG Mining and CORE Alaska entered into the Amended and Restated Limited Liability Company Agreement of Peak Gold JV (“A&R JV LLCA”) on October 1, 2020 to address the new ownership arrangements and to incorporate additional terms that will permit the Peak Gold JV to further develop and produce from its properties. The Company recorded the $32.4 million cash proceeds and the 809,744 shares of Common Stock, received from the CORE Transactions, at fair value and recognized a gain on sale of $39.6 million. The Company valued the Common Stock consideration from the CORE Transactions consistent with the accounting guidance for non-monetary exchanges. The stock consideration was valued based on the implied fair value of the CORE Transactions in total less the cash proceeds. The total value of the CORE Transactions was equated to the value of the Company’s 30.0% ownership in the Peak Gold JV, post the 30.0% membership interest transferred to KG Mining. The Common Stock consideration received in the CORE Transactions is classified within Level 3 of the fair value hierarchy. As of the date of the CORE Transactions, the Company’s investment in the Peak Gold JV had a zero balance, therefore the $39.6 million gain approximates the full fair value of the CORE JV Interest surrendered in the CORE Transactions. The Company recorded a non-current liability totaling $1.2 million associated with the cash received for the reimbursement prepayment to the Company of its proportionate share of certain silver royalty payments that the Peak Gold JV may be obligated to pay Royal Gold. The liability arises, because pursuant to Article IV of the A&R JV LLCA, if the Peak Gold JV terminates, or the Company’s membership interest falls below 5% prior to when the prepaid royalty is paid out, the $1.2 million (less any portion already paid out) is refundable to KG Mining. Prior to the CORE Transactions, the Peak Gold JV was a variable interest entity as defined by FASB ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. The Company was not the primary beneficiary since it did not have the power to direct the activities of the Peak Gold JV. The Company’s ownership interest in the Peak Gold JV has therefore historically applied the equity method of accounting for its investment. After the Kinross Transactions, the Company retained a 30.0% membership interest in the Peak Gold JV. The Company continues to have significant influence in the Peak Gold JV pursuant to its right to designate one of the three seats on the Peak Gold JV management committee. Therefore, the Company will continue to account for its investment in the Peak Gold JV under the equity method.
