A former small surface and underground Ag-Cu-Au-Pb-Zn mine located in the SW¼ sec. 3 and the NW ¼ sec. 9, T.16S., R.4E. (protracted), 9½ miles W of Comobabi. Operated 1850-1965. Owned by Bustamonte; Ehrenberg; Don L.J.F. Jaeger of Yuma; Jaeger & Halstead; Francisco Padres; Choate; Cababi Mining Co.; the Picacho Mining Co.; Bartlett; and, Redhead. Operators included the Picacho Mines Inc.; J.D. Coffman; and, Elden Wilkerson.
Mineralization is faulted, crystalline quartz veins with minor milky quartz, calcite and siderite, with gouge along vein walls, in a major fault zone cutting Cretaceous (?) andesite flows and invaded by andesite and felsic dikes. The ore zone strikes N70E and dips 70NW. Irregular base metal and iron oxides and sulfides. Spotty rich silver values, particularly in the oxidized zone. The sulfides are associated with quartz not carbonates.
Local structures include a major fault zone.
Workings include shaft and pit operations with a length of 304.8 meters and a depth of 182.88 meters. Worked prior to the 1850's and sporadically up to the 1960's. 25 men employed as of 1949. Produced at least 500 tons of ore averaging about 250 oz. Ag/T, 0.3 oz. Au/T and minor Cu & Pb. Produced 240,000 oz. Ag. (before 1914).
