The South Spit (Goodnews Bay) is a chromium and gold mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Geology): Age = Holocene.
Comment (Reference): Primary Reference = Berryhill, 1963
Comment (Workings): Workings / Exploration = Reconnaissance sampling of beach sands was completed in 1958 or 1959 (Berryhill, 1963).
Comment (Geology): Geologic Description = 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.
Comment (Deposit): Model Name = Placer Au-PGE; beach (Cox and Singer, 1986; model 39a)
Comment (Exploration): Status = Inactive
