A former small Pb-Zn-Ag-Cu-Au mine located in the SE¼SW¼ sec. 23, T19S, R15E, G&SRM, on the north side of the upper end of Hughes Gulch 2 miles west of Greaterville, at an elevation of 5,850 feet, 28 miles SE of Tucson, on National Forest land. It was Discovered in 1874. Produced 1874 - ?. The USGS MRDS database stated accuracy for this locality is 10 meters.
Mineralization is 3 quartz-calcite-baryte veins hosted in diorite of the Willow Canyon Formation of conglomerate-siltstone, banded and with comb texture, containing partially oxidized sulfides and small pockets of acanthite in sheared Precambrian granodiorite along a strong fault zone. The ore body is tabular in a fissure vein. The mineraliztion is Neoproterozoic-Late Cretaceous in age (the age of mineralization is believed to be that of the quartz latite intrusive of Drewes - 1971). The primary mode of origin was hydrothermal activity. The veins dip about 55ºS, in coarse, sheared granite. The south vein is about 3 feet wide, the middle one about 2½ feet, and the north one of less width. The veins are parallel and 100 feet apart at the mine; however, 700 feet to the east they converge into one ledge. Associated rocks include diorite (Granodiorite-Precambrian-1450+/-10million years). Local rocks include Cretaceous to Late Jurassic sedimentary rocks with minor volcanic rocks.
Local structures include thrust and normal faulting, fracture zones, homoclinal. Regional trends include tilting and broad open folds in the south and extensive faulting in the north.
Workings include underground openings comprised of 4 inclined shafts sunk on the southern vein. The deepest is reported at about 100 feet deep. Worked in the 1880's.
Production was some 50 or more tons of high-grade Pb-Ag-Au ore. A small amount of shipped ore netted $90/ton (period values). Ore below the supergene blanket had $10 (US) (period values) in Au-Ag per ton.
