A former small underground Cu-Au-Ag mine located in the NE ¼ sec. 3 (1 ?), T.17S., R.5E. (protracted), at the SE base of the South Comobabi Mts, Tohono O'odom (Papago) Indian Reservation, about 4 miles West from the Ajo highway, 6½ miles NE of Sells, and 54 miles from Tucson. Discovered and owned by G.H. Jaeger in 1932. Operated until 1943. Operated by Williams; the Akron Gold Mining Co. (1932- ); and the Desert Gold Mining Co.
Mineralization is a series of parallel, irregular quartz-fissure veins which form a lode; vuggy, composite, oxidized, and enriched near the surface in gold with minor silver and copper, in a Laramide dioritic intrusive containing brecciated blocks of older rocks. The ore zone is narrow at 0.91 meters wide and strikes E-ward and dips vertically. The geological setting is an undulating pediment that exposes small areas of shales intruded by dioritic to rather basic dikes which strike in various directions and have been extensively faulted. SW fault fissures contain abundant limonite together with thin, lenticular, quartz-carbonate veins (quartz associated with more or less calcite) The quartz generally appears in at least 2 generations, of which the later is coarsely crystalline and the earlier is of massive, sugary to dense textured. The Ko Vaya quartz monzonite intruded Jaeger Diorite complex.
Workings include 300 feet (85.34 meters) of shaft workings connecting to some 800 feet (243.84 meters) of underground workings. Produced some 2,800 tons of ore averaging about 0.5 oz. Au/T and 0.3 oz. Ag/T with minor Cu, during the period 1930-1943. Estimated production from $20,000 Au at $32/OZ. In December, 1933, the workings were full of water to within 80 feet of the surface.
