Gold Basin Mine; Malco Mine
A former Au-Cu-Pb-Mo-V-Zn occurrence/mine located in the SE¼ and/or NE¼SW¼ sec. 21, T28N, R18W, G&SRM, in the eastern part of the White Hills about 2 miles West of Hualapai Wash, at 4,000 feet of altitude, on Bureau of Land Management administered land. This mine was started in the late 1870's. Owned in 1907 by the Arizona-Minnesota Gold Mining Company. Owned by C.W. Burcham, Arizona (1958). Produced 1880 to 1906, with ultimate closure in 1940. The USGS MRDS database stated accuracy for this locality is 500 meters.
Mineralization is a polymetallic deposit hosted in schist. The vein is massive white quartz at 2 to 4 foot (0.6 to 1.3 meter) wide with an ore shoot averaging 20 inches wide. The ore body strikes N50E and dips 65SE at a width of 1.22 meters. Schistose, medium-grained, reddish granite is in fault contact with dark biotite granite. The principal vein strikes N50E and dips 65SE. The vein filling within the ore shoot is iron-stained, gold-bearing quartz with malachite, cerussite and vanadinite. The vein seems to average 1 meter thick and dips 25 to 30º ESE on the West side of the workings, and shallowing to nearly horizontal at tunnel portals of the East side of the ridge. Local alteration is propyllitic. Associated rocks include Late Cretaceous-Neoproterozoic quartz monzonite & pegmatite. Local rocks include Early Proterozoic metamorphic rocks.
Workings include surface and underground openings with an overall length of 182.88 meters and an overall width of 60.96 meters. In the 1881 time frame, the workings included some 2,000 feet of adit tunnels plus more than 40,000 cubic feet of stopes on 3 levels. Open pit workings were 8 feet deep. 26,000 tons of ore were developed by 1882.
