A former surface and underground Au-Cu-Ag-Pb-Mo-Fe mine located in the center (or W½) of sec. 21, T5N, R14W (Salome 15 minute topo map), 2 miles NE of Vicksburg and 1 mile W of Winchester Peak. Consisted of 3 patented and 2 unpatented claims in 1942. Mine first opened around 1890. Owned at times, or in part, by Winchester (1911); Vicksburg Development Co.; Desert Mining Co.; Navajo Mines Co.; C.D. Lesher; Haseldel Mining Co.; La. Aplington; Troy; and the All State Mining Co.
Mineralization is a vein deposit with irregular and contorted ore bodies hosted in argillite. It is a wide zone of quartz and calcite veins and stringers, and amorphous quartz, carrying spotty, high-grade gold values and oxidized copper and minor lead-molybdenum ores with iron oxides, following the schistosity of metamorphosed Mesozoic sediments and strikes N-S with a NE dip. Some rhyolite and phonolite extrusives and aplite and basic dikes are present. Gold-bearing gravels are found in gulches near the Desert Mine.
Workings include several small shafts, open cuts and a tunnel The adit is 300 feet long with a raise to the surface. Prospected and worked from the early 1900's throgh 1950. Production would be some 700 tons or more of ore averaging about 0.3 oz. Au/T, 2% Cu and 5 oz. Ag/T.
