It involves the removal of overlying soil, rock, and vegetation to expose the gold-bearing ore. Once the ore is exposed, it is drilled, blasted, and transported to a processing plant for further extraction. The likely parent rocks are sandstone, granite, granodiorite, diorite, limestone, marble, and dolostone (Fig. 7.7). Finely, the granular mylonites are similar to phyllites and generally occur on planes of movement.
