The Unnamed (on Granite Island) is a 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): Geologic Description = The occurrence is described as a 10-centimeter-wide quartz vein which crosscuts coarse-grained, foliated biotite granite. Tysdal and Case (1979) have dated the granite as Eocene.
Comment (Deposit): Model Name = Insufficient information to classify.
Comment (Workings): Workings / Exploration = A surface sample contained, 0.2 PPM Au by A.A. and 150 PPM Cu by semi-quantitative analysis (Tysdal, 1978).
Comment (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Tysdal, 1978
Comment (Reserve-Resource): Reserves = None reported.
Comment (Geology): Age = Eocene or younger; vein cuts Eocene granite.
