Unnamed (beach between Yahtse River and Yana Stream)

The Unnamed (beach between Yahtse River and Yana Stream) is a titanium 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 (Geology): Age = Holocene.

Comment (Reference): Primary Reference = Thomas and Berryhill, 1962

Comment (Workings): Workings / Exploration = Reconnaissance characterization of beach samples has been completed in this area (Thomas and Berryhill, 1962).

Comment (Geology): Geologic Description = Thomas and Berryhill (1962) collected an auger sample of beach sand at this location that contained 0.1 pound of titanium oxide per cubic yard in the magnetic fraction (which also contained 0.6 pound of iron per cubic yard) and 1.2 pounds of titanium oxide per cubic yard in the non-magnetic fraction. It also contained a trace of gold. Beach sands along this segment of the Gulf of Alaska shoreline contain trace amounts of ilmenite, magnetite, rutile, pyrite, garnet, sphene, and zircon (Thomas and Berryhill, 1962).

Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a - beach)

Comment (Exploration): Status = Inactive
