Coeur Closes Acquisition of Remaining Interest in the Joaquin Silver-Gold Project

Coeur d’Alene Mines Corporation (NYSE: CDE) (TSX: CDM) (“Coeur” or the “Company”) is pleased to announce that it has successfully completed the acquisition of the remaining 49% interest in the Joaquin silver-gold project from Mirasol Resources Ltd. (“Mirasol”), previously announced on December 11, 2012, through the acquisition of the Mirasol subsidiary that holds the interest.

Coeur now owns 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.

Donald J. Birak, Coeur's Senior Vice President of Exploration and a qualified person under Canadian NI 43-101, supervised the preparation of the scientific and technical information concerning Coeur's mineral projects in this news release. For a description of the key assumptions, parameters and methods used to estimate mineral reserves and resources, as well as data verification procedures and a general discussion of the extent to which the estimates may be affected by any known environmental, permitting, legal, title, taxation, socio-political, marketing or other relevant factors, please see the Technical Reports for each of Coeur's properties as filed on SEDAR at www.sedar.com.

Cautionary Note to U.S. Investors - The United States Securities and Exchange Commission permits U.S. mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. We may use certain terms in public disclosures, such as "measured," "indicated," "inferred” and “resources," that are recognized by Canadian regulations, but that SEC guidelines generally prohibit U.S. registered companies from including in their filings with the SEC. U.S. investors are urged to consider closely the disclosure in our Form 10-K which may be secured from us, or from the SEC's website at http://www.sec.gov.
