Basis of Presentation [Abstract]
Basis of Presentation	THE COMPANY Coeur Mining, Inc. (“Coeur” or “the Company”) is a gold and silver producer, as well as a zinc and lead producer after the acquisition of Silvertip, with mines located in the United States, Mexico, and Canada and exploration projects in the United States and Mexico. The Company operates the Palmarejo complex as well as the Kensington, Rochester, Wharf, and Silvertip mines. At December 31, 2017, the Company determined that the expected disposal of Empresa Minera Manquiri S.A. ("Manquiri") and the San Bartolomé mine represents a strategic shift to a North America-focused mining portfolio that is expected to have a major effect on the entity's results and operations; therefore, the applicable assets and liabilities for all periods presented are included in the consolidated balance sheets as held for sale and the results of operations as discontinued operations for all periods. The cash flow and profitability of the Company's operations are significantly impacted by the market price of gold and silver. The prices of gold and silver are affected by numerous factors beyond the Company's control.
