Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Palmarejo Gold Stream Coeur Mexicana, S.A. de C.V. (“Coeur Mexicana”), a subsidiary of Coeur, sells 50% of Palmarejo gold production (excluding production from certain properties acquired in 2015) to a subsidiary of Franco-Nevada Corporation (“Franco-Nevada”) under a gold stream agreement for the lesser of $800 or spot price per ounce. In 2015, Coeur Mexicana received a $22.0 million deposit toward future deliveries under the gold stream agreement. In accordance with generally accepted accounting principles, although Coeur Mexicana has satisfied its contractual obligation to repay the deposit to Franco-Nevada, the deposit is accounted for as deferred revenue and is recognized as revenue on a units of production basis as ounces are sold to Franco-Nevada. At September 30, 2019 the remaining unamortized balance was $11.6 million, which is included in Accrued liabilities and other and Other long-term liabilities on the Condensed Consolidated Balance Sheet. Kensington Prepayment In June 2019, Coeur entered into a transaction with an existing metal sales counterparty whereby it amended its existing sales and purchase contract for gold concentrate from its Kensington mine (the “Amended Sales Contract”) to allow for a $25.0 million prepayment for deliveries of gold concentrate from the Kensington mine. In the third quarter of 2019, the Kensington mine delivered approximately $14.7 million of gold concentrate to the counterparty. The remaining deliveries of $10.6 million are recognized as a deferred revenue liability and are presented in Accrued liabilities and other on the Condensed Consolidated Balance Sheet. Under the relevant terms of the Amended Sales Contract, Coeur maintains its exposure to the price of gold and expects to recognize the full value of the accrued liability by the end of 2019. Silvertip Contingent Consideration A total of up to $50.0 million of contingent consideration, payable in cash and common stock, is payable in conjunction with the Silvertip Acquisition. The contingent consideration is based on the achievement of two milestones, which the Company has determined to be probable at September 30, 2019. The first milestone payment of $25.0 million is contingent upon receipt of a permit expansion for a sustained mining and milling rate of 1,000 tonnes per day (the “Permit contingent consideration”). The permit application was required to be submitted to the British Columbia Ministry of Energy and Mining no later than June 2018 and was submitted on April 30, 2018. At September 30, 2019, the Company included the $25.0 million Permit contingent consideration in Accrued liabilities and other on the Condensed Consolidated Balance Sheet. The second milestone payment of up to $25.0 million is contingent upon the amount of resource tonnes added as of December 31, 2019. The former JDS Silver Holdings Ltd. shareholders will receive $5.0 million for a total resource of at least 2.5 million tonnes and $5.0 million for every 0.3 million tonnes over 2.5 million tonnes, up to 3.7 million tonnes (the “Resource contingent consideration”). The maximum payment of $25.0 million can be earned if the total resource (including reserves) reaches 3.7 million tonnes. The Silvertip mine’s total resource (including reserves) was approximately 3.3 million tonnes at December 31, 2018, of which 0.5 million tonnes are classified as inferred resources which are not included in the Company’s mineralized material total reported in the 2018 10-K. At September 30, 2019, the Company included the $24.8 million Resource contingent consideration in Accrued liabilities and other on the Condensed Consolidated Balance Sheet.
