The Unnamed (northeast of upper Partin Creek) is a copper, gold, and silver 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 (Geology): Age = Late Cretaceous or younger.
Comment (Geology): Age = Probably Late Cretaceous or younger.
Comment (Workings): Workings / Exploration = There has been limited exploration consisting of shallow trenches and rock chip samples.
Comment (Deposit): Model Name = Cu skarn (Cox and Singer, 1986; model 18b)
Comment (Reference): Primary Reference = Hawley and others, 1969
Comment (Geology): Geologic Description = The country rocks in the area of this prospect are Upper Triassic limestone and basalt cut by Upper Cretaceous or Lower Tertiary biotite-quartz diorite porphyry. The deposit consists of auriferous skarn containing pyrite, pyrrhotite, chalcopyrite, arsenopyrite, and stibnite. Gold grades are higher near the intrusive contact. Samples contain up to 0.2 ounces of gold per ton and 0.7 percent copper (Hawley and Clark, 1974).
Comment (Exploration): Status = Probably inactive
