A former small underground Ag-Au-Mn-Cu mine located in the SE ¼ sec. 8, T.20S., R.22E. (Tombstone 7.5 minute topo map), 2½ miles SW of Tombstone, on private land. Owned by the San Pedro Leasing Co.

Mineralization is silver chloride and gold values associated with manganese oxide and quartz in an oxidized fault fissure vein in Laramide Uncle Sam Quartz Latite Porphyry. Mineralization also includes oxidized copper minerals. The fissure vein strikes N30E and dips 80NW.

Workings include a shaft with workings on 3 levels.

Several thousand tons of ore were produced in the 1880's and 1890's. A sporadic production of about 2,900 tons occurred from 1936 to 1950. The 1936 & 1937 production figures were included with the Bonanza figures in ABGMT-USBM file data.

Regional Geology

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

Ypresian - Campanian
47.8 - 83.6 Ma



ID: 2847843
Early Tertiary to Late Cretaceous volcanic rocks

Age: Phanerozoic (47.8 - 83.6 Ma)

Stratigraphic Name: Williamson Canyon Volcanics

Description: Rhyolite to andesite and closely associated sedimentary and near-surface intrusive rocks; commonly dark gray to dark greenish gray or greenish brown. In the ranges west of Tucson, this unit includes thick welded ash-flow tuffs. Volcanic rocks of this unit are inferred to be derived from vents and volcanoes above magma chambers that solidified to form the granitic rocks of map unit TKg. These rocks are restricted to southeastern Arizona except for a small outcrop near Bagdad. (50-82 Ma)

Comments: Related, broadly, to unit TKg Original map source: Arizona Geological Survey, DI-8 Geologic Map of Arizona, Digital Spatial data for the Geologic Map of Arizona, v. 3.0, edited by S.M. Richard and S.M. Kneale, 2002, 10 p., 2 DOS HD disks. Arc/INFO export file (.e00) format, scale 1:1,000,000.
