The North 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 (Workings): Workings / Exploration = Reconnaissance sampling of beach sands was completed in 1958 or 1959 (Berryhill, 1963).
Comment (Reference): Primary Reference = Berryhill, 1963
Comment (Geology): Geologic Description = Berryhill (1963) collected five samples of the modern beach along the Bering Sea side of North Spit (Goodnews Bay). Chromite was present in pan concentrates from all of the samples and it was a major constituent in three of them; magnetite was present in about equal amounts to chromite. The iron content of the samples ranged from 1.3 to 6.1 pounds per cubic yard. There was a trace of gold in the three samples that had higher chromite concentrations.
Comment (Deposit): Model Name = Placer Au-PGE; beach (Cox and Singer, 1986; model 39a)
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Holocene.
