    Jun 19, &#; Considering the recovery rate for the silver during the leaching process is substantially lower than for the gold (40% versus 83%), we estimate approximately 60-65% of the 19 million gold-equivalent ounces will be recoverable This paves the way for an initial heap leach operation that would be larger than we originally anticipated.
