Geologic setting

Geologic description

Gold and silver lode claims have been staked in Mesozoic argillite and chert cut by minor quartz veins. Pyrite occurs in the chert and in fault gouge (Kurtak and others, 1992). Selected rock samples contain up to 2 parts per million silver and 105 parts per billion gold (Balen, 1990).

Production and reserves

Workings or exploration Mining claims were staked from 1868 to 1983 (Kurtak and others, 1992). Rock samples collected by U.S. Bureau of Mines (Balen, 1990). The claims are the Fennimore, Betz, Partin Creek 1 and 2, AG 1, Gayboy 1, and Eldridge Glacier (Kurtak and others, 1992).
Indication of production None
