The Mesquite Mine is an operating open pit mine. Mining is performed using a conventional truck/shovel open-pit mining method. Run-of-mine ore is hauled directly to the leach pad for processing.
Mineral processing is by heap leach in a carbon in-column circuit assaying approximately 92% gold. Process recoveries are determined by oxidation. Ultimate gold recovered for the mine reserves and life-of-mine production plan are based on 75% recovery of the oxide ores and gravels and 35% recovery of the non-oxide ores.
Doré is shipped from site to a major refiner where the gold and silver are further refined to bullion. Gold is subsequently sold to bullion banks on the spot market when outturned at the refinery.
