The Goodnews Bay is a platinum 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 = Hoare and Cobb, 1977
Comment (Workings): Workings / Exploration = A core sampling program was apparently completed in Goodnews Bay in 1969. A followup sampling and aeromagnetic survey was apparently completed in 1970 with unknown results (Hoare and Cobb, 1977, p. 35).
Comment (Deposit): Model Name = Placer PGE-Au (Cox and Singer, 1986; model 39a)
Comment (Geology): Geologic Description = Hoare and Cobb (1977, p. 35) reported that core samples of unconsolidated deposits in Goodnews Bay, apparently collected by a private company, contained detectable amounts of platinum. The platinum is said to have been concentrated in clay layers. Most samples also contained cinnabar and native mercury. One tiny diamond is also said to have been found. The highest concentrations were in the north part of the bay, south of Beluga Hill.
Comment (Commodity): Ore Material = Mercury (native)
Comment (Exploration): Status = Inactive
