The Unnamed (Arctic Creek) 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 (Exploration): Status = Inactive
Comment (Geology): Age = Unknown but possibly 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 (Reference): Primary Reference = Sainsbury and others, 1969
Comment (Workings): Workings / Exploration = Some shallow propecting pits may be present.
Comment (Deposit): Model Name = Siliceous zones in marble with pyrite and traces of chalcopyrite
Comment (Geology): Geologic Description = Marble interlayered in pelitic schist forms outcrops just east of the Nome-Taylor road. Sainsbury and others (1969) describe replacements of marble by banded, fine-grained silica containing pyrite and traces of chalcopyrite. Although mapped as klippe by Sainsbury and others (1969), the marble is interlayered with schist and part of a low grade, Lower Paleozoic metasedimentary assemblage (Till and others, 1986).
