The Unnamed (on Kupreanof Peninsula) is a 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 (Reference): Primary Reference = Wilson and others, 1988
Comment (Workings): Workings / Exploration = Rock sample 83ACe52 collected by the U. S. Geological Survey in the mid-1980's, was reported to be anomalous in silver (Wilson and others, 1988).
Comment (Deposit): Other Comments = This site is in the Alaska Peninsula National Wildlife Refuge, near land selected by the Aleut corporation.
Comment (Geology): Geologic Description = This occurrence is in porphyritic dacite that is part of an undivided sequence of late Miocene volcanic rocks (Wilson and others, 1988, 1995). Potassium-argon dating of hornblende in the dacite gave an age of approximately 10 million years (Wilson and others, 1994). One sample collected by the U.S. Geological Survey was reported to contain anomalous values in silver (Wilson and others, 1988).
Comment (Exploration): Status = Inactive
