The Unnamed (beach southwest of Cinder River) is a titanium, iron, and gold 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 (Reference): Primary Reference = Berryhill, 1963
Comment (Workings): Workings / Exploration = In 1963 the U.S. Bureau of Mines drilled 15 holes to test the titanium content of the black sands. The magnetic fraction contained 3.6 to 41 pounds of iron and 1.5 to 9.2 pounds of titanium oxide per cubic yard. The non-magnetic fraction contained 0.4 to 1.6 pounds of titanium oxide per cubic yard. Trace amounts of flour gold were recovered from two of the holes.
Comment (Deposit): Other Comments = This occurrence is located on state land.
Comment (Geology): Geologic Description = This occurrence consists of narrow beach deposits of black sand which occur primarily along the strand line. The black sand forms thin veneers of surf-washed titaniferous magnetite, ilmenite, and pyroxene. To test the sands the U.S. Bureau of Mines (Berryhill, 1963) drilled 15 auger holes along 15 miles of beach. The holes varied from 3.4 to 9 feet in depth. The drill samples were analyzed for iron and titanium oxide.? the magnetic fraction contained 3.6 to 41 pounds of iron and 1.5 to 9.2 pounds of titanium oxide per cubic yard. The non-magnetic fraction contained 0.4 to 1.6 pounds of titanium oxide per cubic yard (Berryhill, 1963). Trace amounts of flour gold were recovered from two of the holes.
Comment (Deposit): Model Name = Shoreline placer titanium (Cox and Singer, 1986; model 39c)
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Quaternary.
