The Reed Creek is a copper, molybdenum, and tungsten 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.

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 = Explored by adit driven in 1917, which is now largely covered by talus (Jasper, 1967). Data on prospect is limited.
Comment (Geology): Age = Late Cretaceous or younger; mineralization is hosted by a Tertiary to Late Cretaceous tonalite.
Comment (Geology): Geologic Description = Low-grade molybdenum-copper mineralization, probably in a pegmatite dike that cuts Tertiary to Late Cretaceous tonalite (Jasper, 1967). Downstream, samples (locality 85 of Cobb, 1972) in stream gravels contain scheelite (Jasper, 1967).
Comment (Exploration): Status = Inactive
Comment (Deposit): Other Comments = Information on deposit is very non-specific. Mackevett and Holloway (1977), assumed deposit to be a pegmatite carrying molybdenite and chalcopyrite probably on the basis of regional geology. Other references mention only low-grade molybdenite-copper mineralization.
Comment (Reference): Primary Reference = Jasper, 1967
