Location: This occurrence is about 4 miles of the modern beach along Kuskokwim Bay from near the north end of South Spit (Goodnews Bay ) south for 1 mile past the village of Platinum. The south limit of this occurrence is the Goodnews A-8 quadrangle boundary; elements of this occurrence continue south to the Hagemeister Island quadrangle. This is locality 11 of Hoare and Cobb (1977) and of Cobb and Condon (1972).
Geology: Berryhill (1963) collected three samples of the modern beach along the Bering Sea side of South Spit (Goodnews Bay). Chromite was present in pan concentrates from all of the samples and it was a major constituent in two of them; magnetite was present in about equal amounts to chromite. The iron content ranged from 1.6 to 3.6 pounds per cubic yard, and there was a trace of gold in all three samples. This occurrence is continuous with chromite- and gold-bearing beaches to the south in the Hagemeister Island D-6 quadrangle (HG001). Hessin and others (1978, [OF 78-9-J; OF 78-9-K; OF 78-9-L; OF 78-9-P]) and Coonrad and others (1978) showed that samples of bottom sediments collected offshore of the present beach contained anomalous concentrations of Cr, Co, Ni, Hg, Au, and Pt in several places.
Workings: Reconnaissance sampling of beach sands was completed in 1958 or 1959 (Berryhill, 1963).
Age: Holocene.
