Coeur d'Alene Mines to Buy Remaining Interest in the Joaquin Silver-Gold Project

Coeur d'Alene Mines Corporation

announced today that Mirasol Resources Ltd. (“Mirasol”) has agreed to sell to Coeur its wholly-owned Argentine subsidiary, Mirasol Argentina SRL, which holds the Joaquin silver-gold project in the Santa Cruz province of Argentina. Coeur currently has a 51% interest in the project. The Company will pay Mirasol total consideration of US$60 million, being approximately US$30 million in cash and 1,310,043 common shares. Mitchell J. Krebs, Coeur's President and Chief Executive Officer, said, “We are pleased to consolidate our ownership in the Joaquin project. We believe Joaquin has substantial exploration upside and the potential to become a significant silver producer for the Company. We intend to continue the drilling program at Joaquin in 2013 and accelerate work on a feasibility study. The subsequent development decision will be based on the economics of the project and our assessment of the political and business environment in Argentina at that time.” Upon completion of the acquisition, Coeur will own 100% of the Joaquin project, which has a recently updated Canadian National Instrument (NI) 43-101 mineral estimate of 38.4 million silver ounces in measured and indicated resources, and 31.3 million silver ounces in inferred resources. In addition, Joaquin contains 39,600 gold ounces in measured and indicated resources and 19,400 gold ounces in inferred resources.
