The Spruce 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 (Workings): Workings / Exploration = A little surface prospecting has probably taken place here.
Comment (Deposit): Model Name = Copper-bearing mineralization in silica-rich zones near marble/schist contact (also see Mount Dixon, SO068).
Comment (Reference): Primary Reference = Smith, 1908
Comment (Geology): Geologic Description = A zone of silicified rock, possibly replaced marble, near a contact with schist contains copper sulfides and carbonates (Smith, 1908; also see Mount Dixon, SO068). Bedrock in Spruce Creek is primarily part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986).
Comment (Exploration): Status = Inactive
