Location and accuracy The approximate location of this gold placer claim, known only from U. S. Bureau of Mines (1977) claim records, apparently is at an elevation of about 400 feet, about 0.2 mile south of the mouth of Red River. The site is in section 5, T. 78 S., R. 99 E., of the Copper River Meridian. It corresponds to loc. 107 in Elliott and others (1978). The location probably is accurate within about 0.3 mile.

Geologic setting

Geologic description

The country rocks in the general area of this prospect include Tertiary or Cretaceous foliated granodiorite and quartz diorite of the Coast Range batholith, and pelitic paragneiss that forms roof pendants and screens in the batholith (Berg and others, 1988). The paragneiss represents marine sedimentary strata that were regionally metamorphosed to amphibolite grade in Cretaceous or Tertiary time. The premetamorphic age of the paragneiss is uncertain, but they probably are mainly Paleozoic and may be as old as Precambrian (Berg and others, 1988, p. 26; Gehrels and others, 1990; Crawford and others, 2000).
According to U.S. Bureau of Mines claim records (1977), this prospect, which appears to be in an area underlain chiefly by granodiorite and paragneiss, was staked as a gold placer claim. No other information about it has been made public.
