Coeur and Palmarejo Silver and Gold File Preliminary Assessment for Palmarejo Silver & Gold Project.

COEUR D'ALENE, Idaho & LONGUEUIL, Quebec -- Coeur d'Alene Mines Corporation (NYSE:CDE) (TSX:CDM) ("Coeur") and Palmarejo Silver and Gold Corporation (TSX-V:PJO) ("Palmarejo") announced today that a preliminary assessment report has been filed on the Palmarejo Project located in Northern Mexico. The purpose of this report is to provide details of the scoping study completed by Coeur that assumes mining at the Palmarejo Project takes place by both open pit and underground mining methods.

Under this scenario, annual production at the Palmarejo Project is anticipated to begin initially by open pit mining methods in late 2008. During the initial five years of operations, production is expected to average approximately 10.4 million ounces of recovered silver and 115,000 ounces of recovered gold with average cash operating costs of negative $0.41 per ounce of silver after gold by-product credits.

The production and cost profiles highlighted above are based on the mining of the following mineral resources within the Palmarejo deposit area only:

For comparison, the total current mineral resources at the Palmarejo Project, including the nearby Guadalupe and La Patria deposits, are as follows:

The study also confirms the earlier reported construction cost estimates of approximately $200 million to achieve commercial production at the Palmarejo Project, including pre-stripping, underground development, mining fleet, power line, ongoing permitting, owner's costs and contingency.

A technical report describing the preliminary assessment is available under the Palmarejo profile on the Canadian Securities Administration website at www.sedar.com.

On May 3, 2007, Coeur, Bolnisi Gold NL, and Palmarejo announced that they entered into agreements, which were approved unanimously by their respective boards of directors, as well as a special committee of independent directors of the Palmarejo board of directors, to merge. Pursuant to the agreements, Coeur will acquire all of the shares of Bolnisi, and all the shares of Palmarejo not owned by Bolnisi, in a transaction valued at approximately US$1.1 billion. As previously reported, the companies expect the transaction to be completed in the fourth quarter of this year.
