The Unnamed (near Tyonek) is a zirconium, iron, and titanium 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.

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 = Cook, 1969
Comment (Deposit): Model Name = Placer Ti (Cox and Singer, 1986; model 39c)
Comment (Deposit): Other Comments = Very limited descriptive information is published on this prospect.
Comment (Geology): Geologic Description = Ilmenite beach sands occur for several miles along the west side of Cook Inlet between the village of Old Tyonek and Shirleyville. Cook (1969, p. 99-105) evaluated this occurrence by concentrating the heavy minerals in a -48 mesh fraction. He noted potentially valuable minerals to be magnetite, ilmenite and zircon. Minor amounts of euxenite, a source of columbium, tantalum and thorium were also noted. Very limited descriptive information is published on this prospect.
Comment (Geology): Age = Quaternary
