Location and accuracy This prospect is known only from U.S. Bureau (1977) claim records. Its approximate location is at an elevation of about 2900 feet on a mountainside facing the southwest shore of an unnamed lake, about 8 miles west-southwest of Hyder. The site is in section 15, T. 69 S., R. 99 E., of the Copper River Meridian. It corresponds to loc. 11 in Elliott and others (1978). The location is probably accurate within about 0.2 mile.

Geologic setting

Geologic description

The country rock in the area of this site is quartz monzonite of the Eocene Hyder Quartz Monzonite batholith (Smith, 1977; Berg and others, 1988). According to U.S. Bureau of Mines claim records (1977), this prospect, which appears to be in (Hyder) quartz monzonite, was staked for Cu, and possibly for Mo. No other information about this prospect has been made public.
