A former small underground Pb-Zn-Ag-Cu-Au mine located in the NE ¼ sec. 23, T.19S., R.15E., on the SE flank of Castle Dome, 3 miles NW of Greaterville, at 5,950 feet of altitude, on private land. Also located 37 miles SE of Tucson. Discovered 1915.
Mineralization is a tabular ore body in a partially oxidized, southwestward-dipping quartz vein which is in the Precambrian granite and is associated with a 2 foot Laramide rhyolite dike that cuts the granite. It Contains spotty pyrite with minor chalcopyrite on the footwall and irregular banded galena, sphalerite and minor pyrite on the hanging wall. The ore is well-banded. The host rock unit is the Willow Canyon Formation.
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 a 65 foot long tunnel. A small tonnage of high-grade Pb-Ag ore shipped in the late 1800's.
