A former Pb-Cu-Zn-Au-Ag occurrence/mine located in sec. 30, T17N, R13E, SBM, 2.5 km (1.6 miles) WNW of Clark Mountain (coordinates of record) (5½ miles NE of Valley Wells). The property comprises 6 claims. MRDS database stated accuracy for this location is meters. Clark (1970a) lists this mine simply as the "Green" Mine.
Mineralization is a vein deposit hosted in quartz monzonite, limestone, and shale. The ore body forms discontinuous lenses at a thickness of 1.68 meters. The veins are narrow. The ore bodies occur along fractures striking N60W and dipping 70NE. Also in cross fractures trending N30E. About 1,500 feet NE of Glory Hole, an ore body 6 inches (15 cm) to 5½ feet thick occurs. Some lenses are terminated by faults. The mine workings are situated along a belt at or near a contact between quartz monzonite and a Paleozoic unit of limestone and shale. Local rocks include Cambrian marine rocks.
Local geologic structures include faults, fractures and cross fractures.
Workings include underground openings including a 285-foot adit and a winze 150 feet from the portal and follows a N60W fracture. 2 drifts, one 30 feet long near the winze, and the other 150 feet long from the adit face, follows cross fractures. A 30-foot adit and a 40-foot shaft were driven into the 6 inch-5½ foot ore body. About 400 feet of prospect adits were driven eastward into limestone in the southern part of the mine area. Shallow openings along a zone 350 yards long mark the removal of high-grade ore pockets. Tucker & Sampson (1943) present more detailed descriptions of the workings.
Production data are found in: Goodwin, Joseph Grant (1957).
A small amount of Au-Ag-Cu ore was produced in 1939. Pb-Zn production is unknown.
Analytical data results: The average value of ore reported to be 20 ounces Ag per ton & 25% Pb.
