Rochester (Nevada)
Rochester is a silver and gold surface mine located in west central Nevada which has produced more than 110 million ounces of silver and 1 million ounces of gold since production began in 1986.
Currently in its residual leaching phase, the mine is expected to continue metals production at operating costs below $1.00 per ounce of silver until approximately 2014 as a result of residual leaching of silver and gold contained in the heaps.
