    Hardrock (Lode) Mining. The vast majority of current gold production comes from commercial hardrock mining operations. In these mines, the gold is extracted from the rock where it was originally deposited. Some hardrock mines are underground mines. A tunnel is drilled or blasted to the source of the ore, which is transported out for processing often by truck or rail.
