A former Au-Ag-PGE (Pt) placer mine located in secs. 17 & 20, T6N, R6E, HM, 1.3 km (4,200 feet) N of Trinity Village, along the Trinity River (on Trinity River 6.5 miles from mouth of South Fork Trinity River) (location given is on river at northernmost point of curve between mile markers 37 and 38 shown on topo map). Owned by the Corona De Oro Mining Co. (1917). MRDS database stated accuracy for this location is 10,000 meters. Alternate coordinates provided: 40°53'11"N, 123°31'52"W.
