A former small underground Cu-Ag-Au mine group located in the North-central sec. 7, the West ½ sec. 8, & the NW ¼ sec. 17, T.13S., R.12E. (Avra 7.5 minute topo map), 11 miles NW of Tucson on National Park land. Operated 1901-1905. Owned at times, or in part, by the Arizona Consolidated Mining Co.; and the Arizona Copper Mining Co.
Mineralization is spotty copper carbonates, oxides, silicates, and sulfides along strongly altered shear zones and fractures in chloritized and silicified Cretaceous andesite and in blocks of dolomite cut by porphyry dikes.
Workings include relatively shallow shafts and tunnels. Intermittent production occurred in the early 1900's. It amounted to some 1,000 tons of ore averaging about 0.7% Cu, 2.6 oz. Au/T and a trace of gold. Probably shipped as smelter flux.
The mines that make up this group have separate crib records, but names were not given to the records due to the lack of information. These other records are field examinations by Roger Ashley in 1974, they are listed here by record numbers: M050870, M050871, M050843, M050899, M050900, and M051017.
