The Unnamed (on Mitrofania Island) is a zinc, lead, and copper 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 = The U.S. Geological Survey mapped and sampled this area in the mid-1980's (Wilson and others, 1988; 1995). Samples of volcanic rock contained as much as 50 ppm copper, 15 ppm lead, and 55 ppm zinc (Angeloni and others, 1985).
Comment (Deposit): Other Comments = This occurrence is on lands selected by the Bristol Bay Native Corporation, near the boundary of the Alaska Peninsula National Wildlife Refuge.
Comment (Reference): Primary Reference = Wilson and others, 1988
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = The country rocks in the area of this occurrence are Tertiary volcanic rocks (Wilson and others, 1995). MacKevett and Holloway (1977) described the occurrence as an altered zone associated with Tertiary granitic rocks, but mapping by the U.S. Geological Survey in the mid-1980's did not indicate any granitic plutons in the general area (Wilson and others, 1995). Samples of volcanic rock collected by the U.S. Geological Survey contained as much as 50 ppm copper, 15 ppm lead, and 55 ppm zinc (Angeloni and others, 1985).
