This district is in southern Inyo County in the Black Mountains about 15 miles west of Shoshone and just east of Death Valley. The chief source of gold has been the Ashford mine, which has a reported output of $135,000, and the Confidence mine. A number of gold-copper-quartz veins occur in gneiss and schist. The deepest workings are about 375 feet. Some high-grade ore has been recovered. The old Ashford mill in Death Valley is now an historical exhibit.
