A former small surface and underground Pb-Cu-Zn-Mo-Ag-Au (V) mine located in the center of sec. 9, T.13S., R.12E, 1 mile ENE of the Tucson Mountain Park. Owned/operated, in whole or in part, by Col. Randolph; the International Ore Separation Co.; Reilly Mines Co.; Consolidated Mining And Milling (1986); and the Tucson Ore Milling Co.

Mineralization is lens-shaped ore masses with partly oxidized base metal sulfides with spotty wulfenite and vanadinite, and quartz and calcite gangue, in a steeply-dipping, lensing, and faulted orebody along a fracture zone cutting Cretaceous andesite and associated with a Laramide porphyritic intrusive. The ore zone is 5 meters wide, strikes N60E and dips 40S. Ore concentration was supergene enrichment. Alteration includes argillitic.

Workings include a shaft and underground workings to at least the 300 foot (95 meter) level. A later open cut exposed underground stopes; numerous shafts, pits. The development of underground workings and heap leach facility occurred in 1984-1986. This mine produced sporadically from 1916 through 1947, with a total of some 5,700 tons of ore averaging about 4% Pb, 1% Cu, 0.6% Zn, 0.3% Mo, 1 oz. Ag/T and 0.1 oz. Au/T. ($3/t Au - period values). Average mine ore contained 2-3% wulfenite.
