A former Mn occurrence/mine/prospect located in sec. 32, T14N, R8E, MDM, 2.5 km (1.5 miles) SSW of Higgins Corner and 4.0 km (2.5 miles) WSW of Lake of the Pines (coordinates of record), and 3 miles NE of the Mangan-chrome Mine, on privately leased land in a state forest area. Discovered in 1943. Owned by George A. Smith., California (1974). Operated by Charles G. Stearns, California (1974). Operated during the period 1940-1942. MRDS database stated accuracy for this location is 10,000 meters. Located 8 road miles N of Auburn; 2 miles S of the Mangachrome Mine.
NOTE: USGS MRDS database file #10115673 presents MRDS files #10034304 and 10261203 as related files. There does not seem to be any relationship to this locality.
Mineralization is a sedimentary Mn deposit hosted in chert. The ore body is 0.61 meter thick. The ore lies in a thick belt, 100 to 500 feet thick, which includes massive white and red chert, bedded white and red chert with shale partings, and greenish cherts, all cut by quartz veins, and some stained by Mn. The cherts strike N20W to N-S and dip 40-80N. It is mostly rhodonite beds, 6 inches (15 cm) to 2 feet (0.61 meter) thick, with with black manganese oxides and containing a few pockets and veins of oxide. Massive brown manganese carbonate and some neotocite overlies the rhodonite. Local rocks include Mesozoic volcanic rocks, unit 2 (Western Sierra Foothills and Western Klamath Mountains).
Workings include surface and underground openings comprised of a 15 foot shaft and an open cut.
No production was recorded.
