The Unnamed (south of mouth of Fishhook Bay) is a zinc, copper, silver, and lead 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.

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 (Deposit): Other Comments = This site is located within the Alaska Peninsula National Wildlife Refuge.
Comment (Deposit): Model Name = Polymetallic vein (Cox and Singer, 1986; model 22c)
Comment (Geology): Geologic Description = The rocks at this site consist of Cretaceous Hoodoo Formation cut by andesite dikes. The U.S. Geological Survey sampled a pyritic quartz vein which cuts hornfelsed siltstone of the Hoodoo Formation at this site (Angeloni and others, 1985). The width of the vein is unknown. The sample of vein material ran 200 ppm antimony, >10,000 ppm arsenic, 1,500 ppm copper, 1,500 ppm lead, 150 ppm silver; and >10,000 ppm zinc.
Comment (Reference): Primary Reference = Angeloni and others, 1985
Comment (Workings): Workings / Exploration = Rock sample (83AWs 57) of vein material collected by the U.S. Geological Survey contained 200 ppm antimony, >10,000 ppm arsenic, 1,500 ppm copper, 1,500 ppm lead, 150 ppm silver, and >10,000 ppm zinc.
Comment (Geology): Age = Tertiary
