After presenting a highly favorable feasibility study in 2004, KCA was awarded an EPCM contract for the mill and heap-leach facilities at this US $104 million gold-silver production complex. Ocampo is comprised of a 4½ million tonne per year heap leach operation with a grinding circuit, an agitated cyanide leach, a low grade Merrill-Crowe gold processing plant, and a high grade Merrill-Crowe gold processing plant with a dry stacked tailings facility to handle 1500 tonnes per day of high-grade ore from the underground mine.
