acquisition of the remaining 49% interest in the Joaquin silver-gold project
from Mirasol Resources Ltd. (“Mirasol”), previously announced on December 11,

Coeur now owns 100% of the Joaquin project, which has a recently updated

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

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.
