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 = Tertiary.
Comment (Reference): Primary Reference = Powers and others, 1960
Comment (Geology): Geologic Description = Pyritic zones are abundant on the western one-third of Amchitka Island. Pyrite in quantities up to one-third of the volume of the rock occurs in volcanic rock of the Amchitka Formation and in sedimentary rocks of the Banjo Point Formation (Powers, 1960, p. 541). The pyrite mineralization tends to follow zones of fractures of diverse strike. One sample assayed trace copper, lead, and zinc.
Comment (Deposit): Other Comments = Site is located in Alaska Maritime Natural Wildlife Refuge.
Comment (Exploration): Status = Inactive
