Commitments and Contingencies Disclosure [Abstract] |
COMMITMENTS AND CONTINGENCIES | COMMITMENTS AND CONTINGENCIES Labor Union Contract The Company maintains a labor agreement with Sindicato de Trabajadores Mineros de la Empresa Manquiri S.A. at the San Bartolomé mine in Bolivia. The San Bartolomé mine labor agreement, which became effective January 28, 2010, is currently active and does not have a fixed term. At December 31, 2015, approximately 11% of the Company’s global labor force was covered by this collective bargaining agreement. The Company cannot predict whether this agreement will be renewed on similar terms or at all, whether future labor disruptions will occur or, if disruptions do occur, how long they will last. Rochester Production Royalty Commencing January 1, 2014, Coeur Rochester is obligated to pay a 3.4% net smelter returns royalty on up to 39.4 million silver equivalent ounces produced and sold from a portion of the Rochester mine, payable on a quarterly basis. For each calendar quarter, the royalty will be payable on the actual sales prices received (exclusive of gains or losses associated with trading activities), less refining costs, of gold and silver produced and sold from the applicable portions of the Rochester mine. Changes in the Company's mine plan and silver and gold prices result in the recognition of mark-to-market gains or losses in Fair value adjustments, net. At December 31, 2015, a total of 26.1 million silver equivalent ounces remain outstanding under the obligation. Palmarejo Gold Production Royalty and Gold Stream On January 21, 2009, Coeur Mexicana entered into a gold production royalty agreement with a subsidiary of Franco-Nevada Corporation under which the subsidiary of Franco-Nevada Corporation purchased a royalty covering 50% of the life of mine gold to be produced from its Palmarejo silver and gold mine in Mexico (excluding production from the recently acquired Paramount properties). The royalty agreement provides for a minimum obligation of 4,167 ounces per month over an initial eight-year period for a total of 400,000 ounces of gold. On October 2, 2014, Coeur Mexicana terminated the Palmarejo gold production royalty in exchange for a termination payment of $2.0 million, effective upon completion of the minimum ounce delivery requirement. Subsequently, Coeur Mexicana entered into a gold stream agreement with a subsidiary of Franco-Nevada Corporation whereby Coeur Mexicana will sell 50% of Palmarejo gold production (excluding production from the recently acquired Paramount properties) upon completion of the gold production royalty minimum ounce delivery requirement for the lesser of $800 or spot price per ounce. Under the gold stream agreement, Coeur Mexicana received a $22.0 million deposit toward future deliveries under the gold stream agreement. Sites Related to Callahan Mining Corporation In 1991, the Company acquired all of the outstanding common stock of Callahan Mining Corporation. The Company has received requests for information or notices of potential liability from state or federal agencies with regard to Callahan's operations at sites in Maine, Colorado and Washington. The Company did not make any decisions with respect to generation, transport or disposal of hazardous waste at these sites. Therefore, the Company believes that it is not liable for any potential cleanup costs either directly as an operator or indirectly as a parent. The Company anticipates that further agency interaction may occur with respect to these sites. Callahan operated a mine and mill in Brooksville, Maine from 1968 until 1972 and subsequently disposed of the property. In 2000, the U.S. Environmental Protection Agency, or EPA, made a formal request to the Company for information regarding the site. The site was placed on the National Priorities List on September 5, 2002, and the Maine Department of Transportation, a partial owner of the property, signed a consent order in 2005. In January 2009, the EPA and the State of Maine made additional formal requests to the Company for information relating to the site, to which the Company responded. The first phase of cleanup at the site began in April 2011. The Van Stone Mine in Stevens County, Washington consists of several parcels of land and was mined from 1926 until 1993 by multiple owners. Callahan sold its parcel in 1990. In February 2010, the State of Washington Department of Ecology notified Callahan that it, among others, is a potentially liable person (PLP) under Washington law. Under lease and option agreements with several owners, Callahan was involved with the Akron Mine located in Gunnison County, Colorado from 1937-1960. The United States Forest Service (“USFS”) made formal requests for information to Callahan regarding the site in December 2003, February 2007, March 2013, and November 2013. Callahan timely responded to each request. In August 2014, Callahan received a notice of potential CERCLA liability from the USFS regarding environmental contamination at the Akron Mine. Callahan and the USFS are currently in discussions regarding this matter. Bolivian Temporary Restriction on Mining above 4,400 Meters On October 14, 2009, the Bolivian state-owned mining organization, COMIBOL, announced by resolution that it was temporarily suspending mining activities above the elevation of 4,400 meters above sea level while stability studies of Cerro Rico mountain are undertaken. The Company holds rights to mine above this elevation under valid contracts with COMIBOL as well as under authorized contracts with local mining cooperatives that hold their rights under contract themselves with COMIBOL. The stability studies have been completed and officially submitted to the Bolivian mining technical authorities. Accordingly, the COMIBOL suspension has expired in accordance with the terms of the resolution. As a result of the resolution, the Company temporarily adjusted its mine plan to confine mining activities to the ore deposits below 4,400 meters above sea level and timely notified COMIBOL of the need to lift the restriction. The Cooperative Reserva Fiscal, with whom the Company has one of those contracts, subsequently interpreted the COMIBOL resolution and determined that the Huacajchi deposit was not covered by such resolution. In March 2010, the Cooperative Reserva Fiscal notified COMIBOL that, based on its interpretation, it was resuming mining of high grade material above the 4,400 meter level in the Huacajchi deposit. In December 2011, the Cooperative Reserva Fiscal sent a similar notification to COMIBOL with respect to a further area above the 4,400 meter level known as Huacajchi Sur. Based on these notifications and on the absence of any objection from COMIBOL, the Company resumed limited mining operations at the San Bartolomé mine on the Huacajchi deposit and Huacajchi Sur. Despite the fact that the COMIBOL suspension has expired, the Company has not resumed mining in other areas above the 4,400 meter level due to community relations concerns and the current political climate in Bolivia. While the COMIBOL suspension has expired, it is uncertain at this time how long the Company will continue to suspend its mining operations in areas above the 4,400 meter level other than at Huacajchi and Huacajchi Sur. If COMIBOL decides to affirmatively adopt a new resolution to restrict access above the 4,400 meter level on a permanent basis, the Company may need to further write down the carrying value of the asset. While a portion of the Company's proven and probable reserves relate to material above the 4,400 meter level at San Bartolomé, so long as operations remain suspended, there is a risk that silver may not be produced from this material at expected levels or at all, particularly given the remaining anticipated mine life of this asset. It is also uncertain if any new mining or investment policies or shifts in political attitude may affect mining in Bolivia.
