A Au-Cu-Ag-W-Ba-Fe-F-U-Mo-Mn mining area located in T5-7N, R13-15W, G&SRM, in the Granite Wash Mountains, with the northern-most portion of the district in the southern fringes of the Harcuvar Mts.

Mineralization is varied: (1) Numerous, irregular, splitting, and lensing veins of quartz, siderite, calcite and brecciated rock containing spotty oxidized and sulfide copper ores, with gold and silver, oftne with strong iron oxides at the surface, in Precambrian schist and gneiss intruded by granite and later cut by numerous dikes of diorite, andesite and rhyolite; (2) Contact metamorphic deposits of copper ores in faulted Paleozoic limestone blocks and adjoining Mesozoic sedimentary formations, intruded by Laramide granite and numerous basic and acidic dikes; (3) Spotty copper and/or lead mineralization, mostly oxidized, in irregular veins and pockets in Mesozoic sediments or Laramide granitic intrusivess, cut by basic and acidic dikes; (4) Tungsten mineralization, with minor copper, associated with quartz lenses in faulted and metamorphosed Paleozoic limestone and underlying Mesozoic sediments, intruded by Laramide granite and cut by diabase dikes. There is some associated placer tungsten; (5)Small, spotty barite lenses with some fluorite and associated iron and manganese oxides, in fissure veins associated with brecciated rock in Precambrian metamorphics cut by dikes; (6) Gold placers in washes below mineralized areas in the Granite Wash Mountains; and, (7) Weak uranium values from unidentified uranium mineralization associated with secondary copper and iron in fissures and faults cutting Precambrian metamorphics and Laramide intrusive granite.

Workings include numerous small prospects and mines scattered through the district from East of Cottonwood Pass, through Tank Pass and along the length of the Granite Wash Mts. The district was prospected and worked sporadically from the late 1800's. Total estimated and recorded production of mined base and precious metals would be some 14,000 tons of ore containing about 385 tons of copper, 2,350 oz. of gold, 14,700 oz. of silver, 12 tons of lead and 4.5 tons of zinc. Also, about 10 tons of tungsten oxide and small shipments of barite ore have been made.
