A former underground Cu-Au-Ag-Fe-U mine located in 22, 23, & 27 and in the NW¼ sec. 26, T7N, R13W, on land of unknown status. Owned and operated by McDonald and Miller of Arizona (1937); and, the Bonanza Central Mining Co. of Arizona (1952). The Bonanza Mining Co. had unspecified involvement here.
Mineralization is spotty copper-gold-silver ores with strong iron oxides and quartz in irregular, lensing veins associated with a wide zone of parallel and persistent diabase dikes, cutting Precambrian gneiss along a strong NW-striking shear zone. Weak uranium mineralization was found on a fracture. An associated rock unit is granite.
Workings include shafts with underground workings down to 500 feet. This mine was discovered about 1900 but was worked mainly and sporadically from 1937 through 1952. Production was some 713 tons of ore averaging about 2% Cu, 0.22 oz. Au/T and 0.2 oz. Ag/T.
