A former Cu mine located in sec. 30, T34N, R5W, MDM, 0.4 km (1,500 feet) ESE of Bohemotash Mountain (coordinates of record), on National Forest land. MRDS database accuracy for this location is not stated.
Mineralization is hosted in rhyolite. The ore body dips NW at 10.67 meters thick and 731.52 meters long. Local rocks include Paleozoic metavolcanic rocks, unit 1 (Eastern Klamath Mountains).
Workings include underground openings with a total length of 365.76 meters. They are comprised of 3 tunnels, one at 400 feet long with a 350 foot raise. The first 90 feet of tunnel No. 1 courses through a secondary deposition caused by leaching of the ore body. The next 50 feet courses through the quartzite footwall with numerous seams bearing sulphide ore. Ore found in tunnel No. 3 is in a disseminated state.
No production reported.
Assay data results: Ore from tunnel No. 1 assayed at 6-14½% Cu.
