Location and accuracy This placer prospect extends for about 2 miles of Nowhere Creek, beginning about 1 1/2 miles upstream from its mouth on the Oshetna River. The prospect is centered in the SW1/4 sec. 27, T. 25 N., R. 8 E., Seward Meridian. The location is accurate to within 1/2 mile.

Geologic setting

Geologic description

Gold occurs in alluvial gravels in Nowhere Creek. The rocks south of the creek are Tertiary volcanic rocks and fluvial conglomerate; the rocks north of the creek are Jurassic volcanic rocks, sandstone, and argillite, intruded by quartz diorite (Csejtey and others, 1978). Quaternary glacial deposits locally cap the bedrock. The alluvial gravels are from 5 feet to more than 40 feet thick and 50 to 100 feet wide. The stream gradient is 100 to 300 feet per mile (Kurtak and others, 1992). Stream-sediment samples contain up to 0.5 part per million silver, 35 parts per million mercury, and 8.6 parts per billion gold; crystalline gold is locally present (Balen, 1990). Placer claims were staked during 1979 by Amend Mining Co.

Production and reserves

Workings or exploration Placer claims were staked during 1979 by Amend Mining Co. Sampling by U.S. Bureau of Mines (Balen, 1990).
Indication of production None
Reserve estimates An estimated 3 million cubic yards of potentially auriferous gravel occurs in the drainage. No grade estimate is given (Kurtak and others, 1992).
