A former surface and underground Cu-Ag-Au-Mo mine located in West-central (NE¼NW¼SW¼) sec. 12, T.15S., R.12E. (Cat Mountain 7.5 minute topo map). Owned/operated at times, or in part, by the Saginaw Mining Co.; Papago Queen Mining Co.; the Tucson Arizona Copper Co.; and Strong & Harris.
Mineralization is disseminated copper oxides and carbonates with minor molybdenum oxides in quartz veins and along fractures in a weakly altered, brecciated, and mineralized Laramide (?) porphyry stock.
Workings include tunnel and open cut operations. Sporadic production of copper ore occurred from 1917 to 1934, and of smelter flux in 1956 through 1959. Total output was some 3,700 tons averaging about 1% Cu and 0.5 oz. Ag/T.
2 valid minerals.

Stratigraphic Name: Temporal Formation; Bathtub Formation; Sand Wells Formation; Fort Crittenden Formation; McCoy Mountains Formation
Description: Sandstone and conglomerate, rarely forms prominent outcrops; massive conglomerate is typical near base of unit and locally in upper part. These deposits are nonmarine except in southeastern Arizona, where prominent gray marine limestone (Mural Limestone) forms the middle of the Bisbee Group. Sandstones are typically medium-bedded, drab brown, lithic-feldspathic arenites. Includes Bisbee Group (largely Early Cretaceous) and related rocks, Temporal, Bathtub, and Sand Wells formations, rocks of Gu Achi, McCoy Mountains Formation, and Upper Cretaceous Fort Crittenden Formation and equivalent rocks. (80-160 Ma)
