Location: This occurrence is on the west flank of Red Mountain, at an elevation of about 650 feet. It is sample locality 44 of Berryhill (1963) and is approximately located, probably within about 1/4 mile. It is locality 6 of Cobb (1972 [MF 362]; 1980 [OF 80-909]).
Geology: Berryhill (1963, sample locality 44) collected a shovel sample of surface materials at this location and determined that the heavy mineral concentrates contained small amounts of chromite (1 to 10 percent) and traces of Pt and Au. Augite, hornblende, and olivine were reported to be present in amounts exceeding 10 percent. This occurrence is on the steeper part of the west flank of Red Mountain, a composite ultramafic pluton containing abundant dunite. The surface materials at this site are expected to be mostly colluvial and to have been derived directly from erosion of the Red Mountain pluton.
Workings: No workings are present.
Age: Holocene.
Commodities (Major) - Cr; (Minor) - Au, Pt
Development Status: None
Deposit Model: Placer PGE-Au (Cox and Singer, 1986; model 39b)
