A former Sn occurrence/mine located in secs. 1, 2, 3, 10 & 11, T4S, R6W, SBM, 5.5 km (3.4 miles) ENE of El Cerrito, about 5 miles SE of Corona and about 11 miles SW of Riverside. MRDS database stated accuracy for this location is 1,000 meters. First produced in 1869 and last in 1928.
Mineralization is a vein deposit. Local rocks include Mesozoic granitic rocks, unit 2 (Peninsular Ranges). The vein was followed to 650 feet of depth but had not bottomed out.
Workings apparently include underground openings in view ofd mthe fact that the vein was followed to 650 feet of depth.
