A former small underground Au-Ag-Cu-Mo-W mine located in the SW ¼ sec. 1 & the SE ¼ sec. 2, T.15S., R.4W., 7 miles W of Gunsight near Balboa Bar; 21 miles SE of Ajo. Owned at times, or in part, by the Black Bess Consolidated Gold Mining Co.; Black Bess Mining Co.; and the Ajo-Papago Gold Mining Co.
Mineralization is spotty oxidized copper minerals with minor scheelite and powellite, enriched in gold near the surface, in quartz-calcite stringers along a fissure zone in decomposed Laramide granitic rock near the contact with Tertiary basaltic andesite.
Workings include shaft operations. The workings are 60.96 meters deep. Originally prospected in the late 1880's but worked and produced sporadically some 80 tons of gold ore between 1918 and 1934.
