A Mn occurrence/prospect located in the NE¼ sec. 23 & in the NW¼ sec. 24, T1S, R13E, MDM, 0.9 km (2,800 feet) ENE of Keystone. Owned by E. M. Jasper, California (1974). MRDS database accuracy for this location is not stated.
Mineralization is a Mn deposit. Banded quartzite (probably metachert) is cut by quartz veins up to 6 inches (15 cm) thick. Manganese stains occur along fractures, and a 1 foot (30 cm) thick zone is partially penetrated by manganese oxides. The quartzite is enclosed in quartz mica schist which strikes N65W and dips 60NE. A serpentine belt lies ½ mile to the NE with green meta-volcanics containing manganese oxide stains along fractures. Rocks strike N40W and dip 70NE. Local rocks include Mesozoic volcanic rocks, unit 2 (Western Sierra Foothills and Western Klamath Mountains).
Workings include unspecified surface openings/operations.
Analytical data results: Probably less than 10% Mn.
