A former underground Cu-Au-Ag mine located in the SE¼ sec. 19, T.15N., R.2E. (Hickey Mountain 7.5 minute topo map), about 1 mile south of the Prescott-Jerome highway, in the western foothills of the Black Hills at an altitude of 5,400 feet. Owned by the Shannon Copper Co. Produced 1890-1949. NOTE:Alternate coordinates provided: 34.66556N, 112.18528W.
Mineralization is a vein deposit with a lenticular ore body hosted in the Spud Mountain Volcanics and Grapevine Gulch Formation. Ore control was faulting and shearing. Ore concentration was oxidation at near surface.
Below the mine white, fissile sericitic schists crop out. At the mine is exposed a dioritic, fine-grained rock showing veinlets of epidote and also veinlets of calcite and bornite; above the mine are vertical greenish slates striking due North and also much of a massive, fragmental rock that is perhaps a diabase tuff. There is a great deal of secondary chlorite, epidote, and calcite.
The mine is in a lithic tuff member of the Grapevine Gulch formation cut by a few narrow diorite porphyry dikes.
Mineralization is a deposit that is a fissure vein striking East and having a dip of 35ºS. The width is as much as 7 feet. It does not extend westward from the Shylock fault. In places there was 3 feet of clear bornite. The ore contains calcite, quartz, bornite, and tennantite with a little pyrite. There is some secondary chalcocite, and also fine azurite and malachite. The structure of the ore is mainly massive, with rather large aggregates of both bornite and tennantite. In places these two minerals are intergrown. More or less oxidized ore occurs near the surface.
Workings include an inclined shaft to the 1300 level, drifts extending mostly to the East a maximum of 750 feet. Production was 9,627,987 pounds of Cu; 2,466 oz. Au; and 77,134 oz. Ag (to 1919). Additional 800 tons of Cu-Ag ore in 1922.
