The Carolusberg Mining Complex has copper reserves of 37.5-million tons, while the Nigramoep deposit has 15-million tons. Galileo's initial tests at their Concordia Copper project near Okiep suggest that prospects are good what it calls "large-scale copper targets". Tungsten has also been found in the area.
