A small former underground Pb-Ag-Zn-Fluorspar-Mn-Fe-Mo-V (Cl-Br) mine located in the center of sec. 11, T4S, R23W (protracted), approximately 3,000 feet south of the Red Cloud Mine and near the edge of Black Rock Wash, on BLM-administered land. An early mine with unrecorded owners, discovered by placer miners sinking to bedrock. Owned by Mr. W.M. Winn (1933).
Mineralization is the Papago vein, which occurs withi the Red Cloud fault zone striking north and dipping steeply east, and one of its NNW-erly branches. The geology is reported to be similar to the Red Cloud Mine but more manganiferous. In the vicinity a northward-trending, steeply eastward-dipping fault zone separates Tertiary volcanic tuffs and andesite flows on the East from Laramide granodiorite on the west. The vein exposed by workings ranges from 1 to 7 feet thick. Outcrops mantled by gravels of the wash. Reportedly assayed up to about 8% Pb and 18 oz. Ag/T.
Workings include 4 or more shafts, distributed over a length of 250 feet, with an unknown amount of drifts and stopes. An assay map (1925) shows the southern or Discovery shaft to be 200 feet deep on a northeasterly incline of 40º to 65º, connecting with some 250 feet of drifts and a few small stopes. The No. 2 shaft, 100 feet farther northwest, connects with an area of stopes about 50 level. These stopes extend approximately 100 feet along the strikes and 10 to 20 feet down the dip. Discovered by placer miners in the early 1880's and reportedly produced considerable silver ore at that time.
