Location and accuracy This site represents approximately 5 miles of sampled beach placer deposits on the Alaska Peninsula on the east coast of Port Moller. The sampling extended northeast from Harbor Point to sec. 33, T. 48 S., R. 72 W., of the Seward Meridian (Cobb, 1972 [MF433], locality 8; Cobb, 1973 [B 1374], locality 3; MacKevett and Holloway, 1977, locality 8; Wilson and others, 1988, locality 8). The sampling extended onto the Chignik A-8 map sheet (see Pilcher, 2000, loc. CG004). The map site is the approximate midpoint of the section of beach sampled, at the west boundary of sec. 15, T. 49 S., R. 73 W., of the Seward Meridian.

Geologic setting

Geologic description

This occurrence consists of beach placer deposits of ilmenite and titaniferous magnetite in a sand spit that is partly moraine. Seven shovel samples were collected over this 5-mile section of beach (Berryhill, 1963). In the magnetic fraction, iron content ranged from 1.1 to 191.4 pounds per cubic yard and the titanium oxide content ranged from 0.3 to 42.4 pounds per cubic yard. In the non-magnetic fraction, titanium oxide ranged to 10.2 pounds per cubic yard (two samples only).
