A former Cr mine located in the NE¼ sec. 15, T6S, R5E, MDM, 5.0 km (3.1 miles) E of Red Mountain and 8.4 km (5.2 miles) W of Copper Mountain (coordinates of record), N of Del Puerto Canyon, on private land. Owned by J. H. Platner (1918). MRDS database stated accuracy for this location is 1,000 meters.
NOTE: Pemberton (1983) refers to this locality as an unnamed Cr occurrence and describes its location rather precisely. Based on that description, it was determined to be the Platner prospect.
Mineralization is hosted in rocks of the Franciscan Formation. Associated rocks include Late Jurassic gabbro, peridotite, dunite and pyroxenite. Alteration is local (serpentinization of ultramafic rocks). Local rocks include ultramafic rocks, chiefly Mesozoic, unit 3 (Coast Ranges and Western Klamath Mountains).
Production information: Less than 150 tons of ore shipped.
