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 June 30, 2020 the remaining unamortized balance was $10.4 million, which is included in Accrued liabilities and other and Other long-term liabilities on the 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, for which deliveries were made to the counterparty in 2019. The Amended Sales Contract also includes an option for an additional $15.0 million prepayment for deliveries of gold concentrate, which Coeur exercised in December 2019. In the first half of 2020, the Kensington mine delivered $15.0 million of gold concentrate to the counterparty in satisfaction of this prepayment obligation. The Amended Sales Contract was further amended in June 2020 to include options for Coeur to receive up to two additional prepayments of up to $15.0 million each for deliveries of gold concentrate from the Kensington mine, and Coeur exercised the option to receive the first $15.0 million prepayment in June 2020 (the “June 2020 Prepayment”). The remaining deliveries of $15.0 million under the June 2020 Prepayment are recognized as a deferred revenue liability and are presented in Accrued liabilities and other on the 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 remaining value of the accrued liability by December 31, 2020. Silvertip Contingent Consideration A total of up to $50.0 million of contingent consideration, payable in cash and common stock, was payable in conjunction with the Silvertip Acquisition based upon the achievement of two milestones, one of which was achieved and paid during 2019 and the other of which was achieved and paid during the first quarter of 2020. The first milestone payment of $25.0 million was 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 submitted to the British Columbia Ministry of Energy and Mining on April 30, 2018 and following its approval in November 2019, the Company made a payment of $25.0 million in the form of $18.7 million in cash and 1.0 million shares of common stock to satisfy the Permit contingent consideration obligation. At December 31, 2019, based on the Silvertip mine’s total mineralized material (including reserves) (the “Resource contingent consideration”), the former JDS Silver Holdings Ltd. shareholders were entitled to the full second contingent payment of $25.0 million. In the first quarter of 2020, the Company made a payment of $25.0 million in the form of $18.8 million in cash and 0.9 million shares of common stock to satisfy the Resource contingent consideration obligation. Mexico VAT Litigation Included in non-current receivables as of June 30, 2020 are $23.0 million due from the Mexican government associated with VAT that was paid under Coeur Mexicana’s prior royalty agreement with a subsidiary of Franco-Nevada Corporation, which was terminated in 2016. Under the royalty agreement, Coeur applied for and initially received VAT refunds associated with the royalty payments in the normal course; however, in 2011 the Mexican tax authorities began denying the Company’s VAT refunds based on the argument that VAT was not legally due on the royalty payments. Accordingly, Coeur began to request refunds of the VAT as undue payments, which the Mexican tax authorities also denied. The Company has since been engaged in ongoing efforts to recover the VAT from the Mexican government (including through litigation). Despite a favorable ruling from Mexican tax courts in this matter in 2018, litigation continues, some of which was determined unfavorably to the Company in 2019 and 2020 based on interpretations of applicable law and prior court decisions which the Company and its counsel believe are erroneous and which are now under appeal. While the Company believes that it remains legally entitled to be refunded the full amount of the VAT receivable, the Company may continue to experience delays or obstacles in the recovery of VAT and it is possible that some or all of the VAT receivable may not ultimately be recovered as outcomes in Mexican tax courts and the process for recovering funds even if there is a successful outcome in litigation can be unpredictable. Other Commitments and Contingencies As part of its ongoing business and operations, the Company and its affiliates are required to provide surety bonds, bank letters of credit, bank guarantees and, in some cases, cash as financial support for various purposes, including environmental remediation, reclamation, collateral for gold hedges and other general corporate purposes. As of June 30, 2020 and December 31, 2019, the Company had surety bonds totaling $212.1 million and $215.6 million, respectively, in place as financial support for future reclamation and closure costs. The obligations associated with these instruments are generally related to performance requirements that the Company addresses through its ongoing operations and from time-to-time, the Company may be required to post collateral, including cash, to support these instruments. As the specific requirements are met, the beneficiary of the associated instrument cancels and/or returns the instrument to the issuing entity. Certain of these instruments are associated with operating sites with long-lived assets and will remain outstanding until closure. The Company believes it is in compliance with all applicable bonding obligations and will be able to satisfy future bonding requirements through existing or alternative means, as they arise.
