An underground Cu-Ag-Mo-U mine located in South-central sec. 9, T.18S., R.12E. (section 2 per MRDS), about 4 miles west of Twin Buttes, on private land. Owned by T.A. Rubley (1954). Operated at times, or in part, by Snyder; Gastellum; Amargosa Molybdenum and Copper Corp.; and General Mines, Ltd. NOTE: Alternate coordinates provided: 31.8714N, 111.1228W.
Mineralization is erratic seams, bunches, and disseminations of copper carbonates and copper and molybdenum sulfides in brecciated, quartzitic rocks intruded by Laramide quartz monzonite porphyry. Molybdenite is associated with chalcopyrite in a plug-like mass of quartz. Radioactivity: Bsckground .16 mr/hr, max.65 mr/hr.
Workings include shaft and adit operations with more than 2,000 feet of underground workings to a depth of 60.96 meters. Much of the workings were filled with water in 1954. Produced sporadically from the early 1900's to 1955 some 2,600 tons of ore averaging about 4% Cu, 0.3 oz. Ag/T and minor Au & Mo. Subhumed by the Esperanza pit.
