A Mn occurrence/prospect located in the NW¼ sec. 35, T20N, R7E, MDM, 2.1 km (6,800 feet) N of Clipper Mills, NNW of Grizzly Lodge, on patented (private) land. Discovered in 1942. Owned by C. F. Shamberger. Operated by Ivan F. Wilson. MRDS database stated accuracy for this location is 1,000 meters.
The ore body is 6.1 meters wide and 9.14 meters long, and crops out over an area 20 feet by 200 feet. Stringers and irregular masses of black manganese oxides in metachert (recrystallized to fine-grained, pure white quartzite). The largest ore outcrop is a fairly pure black psilomelane, comparitively free of quartzite and cut by only a few small quartz veinlets 2 feet wide and 5 feet long. Rocks in the surrounding area are phyllites and sericite schists. Local rocks include Mesozoic volcanic rocks, unit 2 (Western Sierra Foothills and Western Klamath Mountains).
Production information: No production.
Analytical data results: Average grade 10% Mn.
