Location and accuracy
This site represents approximately 20 miles of sampled beach placer deposits on the Alaska Peninsula along the coast of Bristol Bay.
Sampling extended northeast from sec. 22, T. 49 S., R. 80 W., of the Seward Meridian on Port Moller D-5 quadrangle to Lagoon Point on Port Moller D-4 quadrangle (Cobb, 1972 [MF 433], locality 7; Cobb, 1973 [B 1374], locality 2; MacKevett and Holloway, 1977, locality 7; Wilson and others, 1988, locality 7). This site is plotted near the midpoint of the sampled section of beach, on the boundary of secs. 5 and 6, T. 49 S., R. 78 W., of the Seward Meridian.

Geologic setting

Geologic description

This occurrence consists of beach placer deposits of ilmenite and titaniferous magnetite in a long spit covered by sand dunes up to 40 feet above water table. Fourteen drill and seven shovel samples were dug along this 20-mile section of beach (Berryhill, 1963). In the magnetic fraction, iron content ranged from 4.9 to 309.7 pounds per cubic yard and the titanium oxide content ranged from 1.2 to 70.2 pounds per cubic yard. In the non-magnetic fraction, titanium oxide content ranged from 0.8 to 8.5 pounds per cubic yard.
