Coeur Receives Approval for Rochester Expansion
The Rochester expansion project is expected to increase the mine’s average annual production to more than 2.4 million oz of silver and 35,000 oz of gold over a period of several years, representing a substantial increase from projected production of 700,000 oz/y of silver and 5,000 oz/y of gold from existing residual leaching operations. Current estimates call for Rochester to produce a total of 19.5 million oz of silver and 252,000 oz of gold over the period 2011-2018.
A recently completed and updated feasibility study of the expansion plan was based 27.6 million oz of contained silver and 247,000 oz of contained gold in proven and probable reserves of 48.3 million st at average grades of 0.57 oz/st silver and 0.005 oz/st gold, based on metal prices of $1,205/oz gold and $16.25/oz silver.
