The Unnamed (west of Chirikof Point) is a iron 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 (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Gates and others, 1971
Comment (Geology): Geologic Description = On Attu Island partly oxidized zones of pyrite occur in many rock types, including basalt and andesite flows and pyroclastics (Gates and others, 1971). The zones range in size from small isolated pods a few feet in diameter to broad areas 2 to 3 miles long and one mile wide. Many elongate zones or small, isolated patches trend or are aligned east-west. At Chirikof Point pyritic mineralization is associated with flows and hornblende-bearing dikes and shows evidence of silicification and albitization with accompanying epidote and chlorite. The mineralized zones carry traces of copper and lead.
Comment (Geology): Age = Tertiary or younger.
Comment (Deposit): Other Comments = Site is located within Aleutian Maritime Wildlife Refuge.
