Coeur d’Alene Mines Announces Withdrawal of Proposed Offering of Senior Notes

COEUR D’ALENE, Idaho—Jul. 3, 2012— Coeur d’Alene Mines Corporation (the “Company” or “Coeur”) (NYSE: CDE)(TSX: CDM) today announced that in light of current capital market conditions it has decided not to proceed with its previously announced offering of senior notes at this time.

“Weak overall conditions in the debt markets led us to conclude that the proposed offering of senior notes would not be in the best interest of shareholders under the terms currently available,” stated Mitchell J. Krebs, President and Chief Executive Officer. “We had hoped to opportunistically access the debt markets to augment our already strong balance sheet, but we will only do so in a disciplined manner. We will continue our focus on creating shareholder value through operational consistency, cost containment, disciplined growth, and maintaining a conservative financial profile.”
