    The process used by Minera Penmont to extract gold from ore is known as heap leach. In this process, the ore is staked in layers on an impermeable membrane known as leach pad. The cyanide solution is dripped onto to the heap by a drip irrigation system. The solution percolates through the heap leaching the gold from the ore.
