Location and accuracy This placer prospect is on Second Creek, an informally named feature that is a north tributary to the Susitna River, whose mouth is about 6 miles downstream from Jay Creek. A placer claim is at about the 2,500-foot elevation on Second Creek; the upper end is accurately located in the SW1/4 sec. 32, T. 32 N., R. 8 E., Seward Meridian. This is locality B27 of Kurtak and others, (1992).

Geologic setting

Geologic description

The prospect is in Quaternary glacial and alluvial deposits (Kurtak and others, 1992). In 1976, a placer claim was staked and assessment work was done through 1983 (Kurtak and others, 1992). Placer samples collected by the U.S. Bureau of Mines contain up to 0.0002 ounce of gold per cubic yard and 1 percent barium (Balen, 1990). The placer concentrates also contain abundant garnet and magnetite.
