A former underground Pb-Ag-Fe-Zn-Mo mine located in East-central sec. 11, T4S, R23W, north of the Black Rock Mine and east of the Pacific Mine, on BLM-administered land. Owned at times, or in part, by Cargill; Messrs. W.D. Riley, A.B. Ming & R.A. McPherson of Yuma (1933).
Mineralization and geology is similar to that of the Black Rock Mine. Small lead of quartz, iron oxide, manganiferous calcite with spotty bunches of partly oxidized galena and cavities filled with limonite and wulfenite crystals in a broad, brecciated fault zone offset by traverse faults and with siliceous cement. The wall rocks are metamorphosed schist. The fault zone strikes S.15ºW. and dips 45ºSE, but steepens somewhat with depth.
Workings include a tunnel more than 200 feet (76.2 meters) long; and an old shaft reported at about 200 feet (60.96 meters) deep. This claim was patented in 1881 and may have produced some silver ore in the early days.
