Köppen climate type:
A Cu-Ag-Au, silica, feldspar, mica (Mo-Zn) mining area located in T.12-13S., R.6-7W., in the Little Ajo Mountains and Chico Shuni Hills.
Mineralization is varied: (1) Cu-Ag & Au mineralization on fracture planes and disseminated in brecciated Laramide intrusive and adjacent Cretaceous volcanics. Some local, high-grade, narrow, irregular vein-like deposits in volcanics and spotty occurrences near fault zones in volcanics and intrusive. Erratic secondary copper mineralization in fanglomerate; (2) Pegmatite veins and masses in Mesozoic granitic intrusive; and, (3) Spotty, irregular gold placers.
Workings include predominantly open pit mining operations. Small, irregular production of high-grade, oxidized copper ore occurred from about 1854 to 1917 and almost continuously thereafter from the open pit operations. Total production through 1972 would amount to some 350,000,000 tons of ore containing about 2,800,000 tons of Cu, 19,000,000 oz. of silver, and 1,550,000 oz. of gold. Considerable silica flux and some feldspar and scrap mica were also produced.
