The Dead Creek is a zinc, copper, and lead 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 (Deposit): Other Comments = New location based on information provided by J.M. Proffett, 1997. Information from Nana Development Corporation (1997) based on 1984 unpublished Bear Creek Exploration report.
Comment (Deposit): Model Name = Kuroko
Comment (Workings): Workings / Exploration = Explored by several diamond drill holes and surface geologic mapping (Nana Development Corporation, written comm., 1997)
Comment (Reference): Primary Reference = Sichermann and others, 1976
Comment (Geology): Geologic Description = This deposit consists of coarse disseminated grains and semi-massive lenses of sulfide minerals hosted by south dipping coarse grained quartz-muscovite schist. The schist is interlayered with greenstone(metabasalt) and locally interbedded with thin quartzite beds.The two ore horizons are complexly deformed to pinch and swell structure and are cut off to the east along strike by a discordant body of greenstone. Some concordant greenstone may be tuffaceous or argillaceous dolomite. This schist belt type volcanogenic Cu-Zn deposit is similar to the Arctic deposit (AR025) (unpublished Bear Creek Exploration Report, 1984).
Comment (Geology): Age = Devonian-Mississippian
