Geologic setting

Geologic description

Mertie (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).
