A former small underground Cu-Pb-Ag-Au mine located in the SW ¼ sec. 19 (& NW¼ sec. 30 ?), T.11S., R.3E. (protracted) (Gu Achi 15 minute topo map), in the Cimarron Mountains, 9½ miles NW of Gu Achi. Produced 1920-1935. Owned by the Montizona Copper Co.
Mineralization is spotty, argentiferous and auriferous copper carbonates, sulfides, oxides and silicates in brecciated quartz-fissure veins along a fault zone in Laramide granodiorite. Numerous aplite, trachyte and andesite dikes. High grade oxidized Cu ore.
Workings include shafts, tunnels and diamond drilling operations. Developed in the late 1920's and mid-1930's, but only shipped some 15 tons of high-grade, oxidized copper ore averaging about 67% Cu, 8 oz. Ag/T, 7% Pb and 0.1 oz. Au/T.
