Mining is done by block caving.In 1980 the cavity produced by the panel caving broke through to the surface, producing a large glory hole (subsidence) on the side of Red Mountain.. The ore is carried by a 15-mile (24 km) conveyor belt system extending through a 10-mile (16 km) tunnel beneath the Continental Divide and then five miles (8 km) overland to the ore processing mill near Parshall
