Commitments and Contingencies Disclosure [Abstract] |
COMMITMENTS AND CONTINGENCIES | COMMITMENTS AND CONTINGENCIES Palmarejo Gold Stream Effective August 2016, Coeur Mexicana sells 50% of Palmarejo gold production (excluding production from the Paramount properties acquired in 2015) to a subsidiary of Franco-Nevada Corporation 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 has satisfied its contractual obligation to repay the deposit to the subsidiary of Franco-Nevada Corporation, the deposit is accounted for as deferred revenue and is recognized as revenue on a units of production basis as ounces are sold to the Franco-Nevada Corporation subsidiary. As of December 31, 2017, the remaining unamortized balance was $14.9 million. Silvertip Contingent Consideration A total of $50.0 million of contingent consideration, payable in cash and common stock, was offered in conjunction with the Silvertip acquisition in October 2017. The contingent consideration is based on the achievement of two milestones, which the Company has determined to be probable at December 31, 2017. 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 application must be submitted to the British Columbia Ministry of Energy and Mining no later than June 2018. The second milestone payment of $25.0 million is contingent upon the amount of resource tonnes added as of December 31, 2019. The maximum payment of $25.0 million can be earned if the total resource reaches 3.7 million tonnes. The former JDS Silver 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.
