A former surface & underground Au-Cu-Pb-Mo-V-Zn mine located in the SW ¼ sec. 21, T.28N., R.18W., in the eastern part of the White Hills about 2 miles West of Hualapai Wash, at 4,000 feet of altitude. Owned in 1907 by the Arizona-Minnesota Gold Mining Co.
Mineralization is a 2 to 4 foot (.6 to 1.3 meter) wide vein with an oreshoot averaging 20 inches wide. Schistose, medium-grained, reddish granite is in fault contact with dark biotite granite. The principal vein strikes N.50ºE. and dips 65º SE. The vein filling within the oreshoot 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 nearlyu horizontal at tunnel portals of the East side of the ridge.
This mine was started in the late 1870's. Workings in 1881 timeframe included some 2,000 feet of adit tunnels plus more than 40,000 cu. ft. of stopes on 3 levels. 26,000 tons of ore were developed by 1882. Produced 1880 to 1906, with ultimate closure in 1940.
