The Unnamed (on Glacier Creek) is a silver, gold, and zinc 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 10-foot-long adit was driven on a pyrite-bearing shear zone in limestone (Still and others, 1991).
Comment (Deposit): Model Name = Mineralized shear zone in limestone.
Comment (Geology): Geologic Description = Still and others (1991) describe this prospect as a 10-foot-long adit driven along a pyrite-bearing shear zone in limestone. Samples from the adit and its vicinity contained up to 0.59 ppm gold, 3 ppm silver, 1,100 ppm zinc, 550 ppm copper, and 140 ppm lead. The limestone unit is Paleozoic (MacKevett and others, 1974) possibly, Late Pennsylvanian or Early Permian (Eakin, 1919).
Comment (Geology): Age = Probably Late Paleozoic or younger based on the age of the limestone (MacKevett and others, 1974; Eakin, 1919).
Comment (Reference): Primary Reference = Still and others, 1991
Comment (Exploration): Status = Probably inactive
