A former small underground Cu-Ag-Au-Pb-Zn-Mn-Mo mine located in the center (NEΒΌSWΒΌ) of sec. 1, T.23S., R.15E, 1 mile SSW of the European Mine, 13 miles NE of Nogales in Cox Gulch, on National Forest land. The property consists of 130 claims, presumed to be unpatented, in 1965. Produced 1913-1950. Owned at times, or in part, by Mr. A.S. Henderson; Ventura Mines,Inc.; Mr. G.W. Morris; and, Mr. Rupert Beyerle (Byerle ?). Operated by the Arizona Smelting and Refining Co.(1979). Owned by Noranda Mines, Ltd. (1979).
Mineralization is quartz-gouge veins with spotty pyrite, chalcopyrite, chalcocite and minor galena and sphalerite, roughly banded, along fissures and joints in strongly silicified and weakly mineralized Precambrian metamorphosed volcanics and sediments intruded by Jurassic granite, which is found 0.25 mile from the deposit. The quartz-gouge veins have unknown dimensions. The large ore lens associated with the shear zone is 500 feet long, 30-200 feet wide, and dips 70 degrees and plunges NE. Oxidation produced abundant iron oxide and psilomelane. Alteration includes silicification, oxidation (Sericite-Quartz-Tourmaline). The host rock unit is the Mt. Wrightson formation.
Workings include tunnel operations and total 1524 meters in length. The series of tunnels are on the E side of the mountain, one above the other. Extensive diamond drilling was conducted on the property. Sporadic production occurred in 1913 and from 1933 through 1950. Some 440 tons of ore were produced, averaging about 6% Cu, 16 oz. Ag/T, 1% Pb, and 0.2 oz. Au/T.
