Location and accuracy This site represents 5 miles of beach placer deposits on the northwest coast of the Alaska Peninsula extending for approximately 5 miles southwest of Franks Lagoon onto the Port Moller 1:250,000-scale map sheet (Cobb, 1973: B-1374, locality 3; MacKevett and Holloway, 1977, locality 4). The maps site is plotted at Franks Lagoon.

Geologic setting

Geologic description

This occurrence consists of beach placer deposits of magnetite and titaniferous ilmenite in well-developed sandy spits extending 5 miles southwest of Franks Lagoon.
Berryhill (1963) collected 11 auger samples and a few shovel samples along this 5-mile section of beach. These samples were screened, tabled, and run through a magnetic separater. The magnetic fraction contained 1.1 to 191.4 pounds iron per cubic yard and 0.3 to 42.2 pounds titanium oxide. The non-magnetic fraction contained 0 to 10.3 pounds per cubic yard titanium oxide.

Age of mineralization Quaternary.

Production and reserves

Workings or exploration The magnetitic fraction of 11 auger and shovel samples collected in 1963 contained 1.1 to 191.4 pounds iron and 0.3 to 42.2 pounds titanium oxide per cubic yard. The non-magnetic fraction contained 0 to 10.3 pounds titanium oxide per cubic yard.
Indication of production None
