Rochester (Nevada)

Coeur's 100% owned Rochester Rochester mine has produced more than 125 million ounces of silver and 1 million ounces of gold since production began in 1986.

The active mining of ore at the Rochester mine was completed during 2007; however, silver and gold production is expected to continue through 2014 as a result of continuing heap leaching operations.

During 2009, the Company completed a technical and economic evaluation of an expansion of mining operations at its Rochester mine. This study envisions an average of 2.9 million ounces of incremental annual silver production and 30,000 ounces of further gold production through 2017.

Coeur expects to complete the permitting necessary for construction of facilities to restart active mining in the second half of 2010. Rochester produced 2.2 million ounces of silver and 12,663 ounces of gold in 2009.

.Rochester is currently pursuing resumption of Active Mining in 2010. 

• Silver and gold mineral reserves at year-end totaled 25.9 million ounces of silver and 232,000 ounces of gold.
