Arizona Bureau of Mines file data.
A Cu-Ag-Au-Pb-Zn-Mn mine located in the SW ¼ sec. 3 & the N ½ sec. 10, T.23S., R.15E. Owned at times, or in part, by Stockton; Backman & Merritt Mines Co.; Monarch Mining & Milling Co.; Taft Mining & Exploration Co.; Melville Syndicate; Newcomer; and, Cummings.
Mineralization is lenses of argentiferous galena with minor chalcopyrite and sphalerite in a quartz, psilomelane, and gouge gangue in fissure-zone veins, oxidized to cerussite, acanthite, and rich chlorargyrite pockets. The wall rock is strongly sheared and fractured Precambrian rock intruded by Jurassic granite. A major fault passes through the area and a Northeast-striking fracture zone contains weak, oxidized sulfide mineralization. Psilomelane often contains lead and silver values.
Workings include shaft operations. Worked by Mexicans prior to 1880 but mainly from 1910 through 1942, producing in total some 200 tons of ore averaging about 70 oz. Ag/T, 25% Pb and minor Cu & Au.
