Location and accuracy Smalls River is the main drainage on the north side of Red Mountain. This prospect is about 1.5 miles from Kuskokwim Bay along the Platinum to Goodnews Bay Mining Camp road. The location is an exploration drill hole that was drilled along the north side of the road. The map site is inthe SW 1/4 of section 2, T 14 S, R 75 W, of the Seward Meridian. The location is very approximate, probably to within 1.2 mile. This prospect is locality 5 of Cobb (1972 [MF 362]; 1980 [OF 80-909]).

Geologic setting

Geologic description

Mertie (1969, p. 81; 1976, p. 5) reports that a 192-foot-deep exploration drill hole at this location intersected platinum- and gold-bearing material but it was apparently only a local concentration. Smalls River is the main drainage on the north side of the Red Mountain ultramafic pluton.
