|Location and accuracy||This occurrence is on the summit of Red Mountain. The location is probably accurate to within about 1/4 mile. It is locality 8 of Cobb (1972, [MF 362]; 1980 [OF 80-909]).|
Geologic descriptionMertie (1969, p. 84) reported that the heavy mineral concentrate from a sample of residual surface material at this location contained platinum. The residual surface material rests on dunite of the composite Red Mountain ultramafic pluton and upslope to the northwest of a large platinum-in-soil anomaly over this pluton (HG006).
