Development Of A Strategic Mine Plan At Coeur Rochester, Inc.

Coeur Rochester Inc. located in north central Nevada, operates an open pit mine moving a total of 16 - 18 million short tons of material per year. A three stage crusher produces approximately 8 million tons of a minus half inch product that utilizes truck stacking to construct a heap leach with a zinc precipitation recov­ery plant. Coeur Rochester recovers approximately 6.0 - 7.0 MM ounces of silver and 60 - 80 K ounces of gold annually. Current metal prices and good operating practices require contin­ued review of operating systems that support the operation, thus the development of a Strategic Mine Plan. This Strategic Mine Plan provides managers, engineers and supervisors a means to improve their operations through three main objectives: 1. Reduce operating costs, 2 .. Increase production, 3. Increase mine life (reserves). These three main objectives will be reviewed in context to their current status and past performance.
