The Unnamed (northeast of upper Eddy Creek) is a zinc and 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 = This occurrence was discovered by the Anaconda Mineral Company between 1980 and 1982 (Flanigan, 1998).
Comment (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Flanigan, 1998
Comment (Deposit): Model Name = Plutonic-related Cu-Zn
Comment (Geology): Age = Flanigan (1998) suggests that this occurrence is probably related to the Round Top (NL011) quartz monzonite intrusive complex, for which K-Ar and Ar/Ar dates indicate cooling at approximately 75 Ma.
Comment (Geology): Geologic Description = This occurrence consists of scattered gossan in variably graphitic quartz schist adjacent to a greenstone(?) dike (Flanigan, 1998). Seven rock samples contained up to 191 ppm copper, 373 ppm zinc, 1.1 ppm silver, and 62 ppm molybdenum. Flanigan (1998) suggests that this occurrence is probably related to the Round Top (NL011) quartz monzonite intrusive complex, for which K-Ar and Ar/Ar dates indicate cooling at approximately 75 Ma. Also see NL002, 008, 010, and 011.
