The Icy Bay (northeast of Clay Bluff Point) is a gold 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.
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 = Thomas and Berryhill, 1962
Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a - beach)
Comment (Geology): Geologic Description = Thomas and Berryhill (1962) collected reconnaissance beach samples (IB004, IB006, IB007, IB009, IB010) from the Icy Bay area that contained trace to small amounts of magnetite, ilmenite, chromite, zircon, rutile, garnet, sphene, xenotime, and gold. The magnetic fraction of their samples contained as much as 6.2 pounds of iron and 1 pound of titanium oxide per cubic yard. The non-magnetic fraction in these samples contained as much as 6.4 pounds, but mostly less than 2 pounds, of titanium oxide per cubic yard. An auger sample of beach material collected by Thomas and Berryhill (1962) at this location contained 0.1 pound of titanium oxide per cubic yard in the magnetic fraction (which also contained 0.4 pound of iron per cubic yard) and 0.5 pound of titanium oxide per cubic yard in the non-magnetic fraction. It also contained a trace of gold.
Comment (Workings): Workings / Exploration = Reconnaissance characterization of beach samples has been completed in this area.
Comment (Geology): Age = Holocene.
Comment (Exploration): Status = Inactive
