The Unnamed (north of Anchor Bay) is a 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 (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Wilson and others, 1988
Comment (Workings): Workings / Exploration = Rock sample 83AYb509, collected by the U.S. Geological Survey in the mid-1980's, was reported to be anomalous in copper and arsenic (Angeloni and others, 1985; Wilson and others, 1988).
Comment (Geology): Age = Eocene or younger.
Comment (Deposit): Model Name = Polymetallic veins (Cox and Singer, 1986; model 22c)
Comment (Deposit): Other Comments = This site is located on land interim-conveyed to, or patented or selected by, the Bristol Bay Native corporation.
Comment (Geology): Geologic Description = This occurrence is hosted by volcanic units of the Eocene to Oligocene Meshik Formation (Wilson and others, 1995). It consists of fractured and iron-stained volcanic flows cut by pyrite-bearing, vuggy quartz veins (Wilson and others, 1988). One sample collected by the U.S. Geological Survey is reported to contain anomalous values in arsenic and copper (Angeloni and others, 1985; Wilson and others, 1988).
