The Unnamed (north of Inyuilak Creek) is a zinc, tin, copper, bismuth, and silver 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 (Workings): Workings / Exploration = Site briefly examined during regional geologic mapping by the USGS in the late 1970s.
Comment (Reference): Primary Reference = Grybeck and Nelson, 1981
Comment (Geology): Age = Devonian; related to the intrusion of Devonian pluton.
Comment (Geology): Geologic Description = This occurrence is a contact metamorphic deposit at the contact of Devonian granite and Paleozoic schist (Grybeck and Nelson, 1981). Selected samples contain up 5 ppm Ag, 100 ppm Bi, 1 percent Cu, 30 ppm Sn, and 700 ppm Zn. The deposit is related to intrusion of the granite and is similar to other contact-metamorphic deposits in the Brooks Range (Newberry and others, 1986).
Comment (Deposit): Model Name = Skarn (Cox and Singer, 1986; model 14b)
Comment (Deposit): Other Comments = Located within Gates of the Arctic National Park.
Comment (Exploration): Status = Inactive
