The Unnamed (near Mt. Distin) is a copper and gold 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; mineralization is interpreted to be linked to the Late Cretaceous diorite that is mapped as one of the 67 m.y. old Kichatna plutons by Reed and Nelson (1980).
Comment (Deposit): Model Name = Polymetallic veins (Cox and Singer, 1986; model 22c).
Comment (Geology): Geologic Description = A small plug of Late Cretaceous (67 m.y.) diorite, assigned to the Kichatna plutons (TKk), intrudes Mesozoic flysch (KJs) in this area (Reed and Nelson, 1980). Cominco American Incorporated (unpublished report) describes vuggy veins, veinlets, and breccia of quartz-pyrrhotite- pyrite-chalcopyrite-and/or arsenopyrite that cut both the sedimentary and intrusive rocks. A similar occurrence is noted in Old Man Creek (TY026) in the Tyonek quadrangle.
Comment (Workings): Workings / Exploration = Prospecting, silt and rock chip geochemistry and mapping at 1:12,000 scale by Cominco American Incorporated in the late 1980s.
Comment (Reference): Primary Reference = This record
Comment (Exploration): Status = Inactive
