The Unnamed (Kougarok River) is a copper 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 (Reference): Primary Reference = Smith, 1908
Comment (Workings): Workings / Exploration = No workings are known for this occurrence.
Comment (Geology): Age = Unknown; if epigenetic then perhaps Cretaceous. The major episode of epigenetic mineralization on Seward Peninsula accompanied higher temperature metamophism and mid- to Late Cretaceous granitic plutonism in the region.
Comment (Geology): Geologic Description = Smith (1908, p, 244) reports that copper sulfides (chalcopyrite ?)are present in metamorphosed limestone (marble) on Kougarok River somewhere near the mouth of Taylor Creek. Bedrock in the upper Kougarok River area is part of a lower Paleozoic metasedimentary assemblage (Sainsbury and others, 1969; Till and others, 1986).
Comment (Deposit): Model Name = Chalcopyrite in marble ?
Comment (Exploration): Status = Inactive
