The Port Heiden is a 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.
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 (Deposit): Model Name = Shoreline placer titanium (Cox and Singer, 1986; model 39c)
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Quaternary.
Comment (Workings): Workings / Exploration = The magnetic fraction of 24 auger samples collected in 1963 contained 2.2 to 103.6 pounds iron and 0.6 to 21.9 pounds titanium oxide per cubic yard. The non-magnetic fraction contained 0 to1.2 pounds titanium oxide per cubic yard.
Comment (Reference): Primary Reference = Berryhill, 1963
Comment (Geology): Geologic Description = This occurrence consists of beach placer deposits of ilmenite and titaniferous magnetite in narrow spits and bars along the outer shores of low-lying mudflats. The beaches are sandy gravel, often loosely packed.? Twenty-four auger samples were collected along this 20-mile section (Berryhill, 1963). They were screened, tabled, and run through a magnetic separator. In the magnetic fraction iron content ranged from 2.2 to 103.6 pounds per cubic yard, and the titanium oxide content ranged from 0.6 to 21.9 pounds. In the non-magnetic fraction the titanium oxide content ranged from 0 to 1.2 pounds per cubic yard. A trace of flour gold was present in 5 samples.
Comment (Deposit): Other Comments = This site is located on state land, part of which is in the Port Heiden Critical Habitat Area.
