Coeur d'Alene Mines Corporation says its Rochester Mine near Lovelock produced 640,347 ounces of silver and 3,617 ounces of gold in the fourth quarter of 2009.
The Idaho-based company, which currently processes only previously mined ores at the property, is studying the resumption of active mining.
It says studies indicate the mine could operate for six more years, producing 2.5 million ounces of silver and 33,000 ounces of gold annually.
