|Location and accuracy||This prospect is known only from U.S. Bureau of MInes (1977) claim records. Its approximate location is at sea level at about the midpoint of the northeast shore of the southeast arm of Traitor's Cove. The site is in section 21, T. 71 S., R. 90 E., of the Copper River Meridian. It corresponds to loc. 27 in Elliott and others (1978). The location is probably accurate within 0.5 mile.|
Geologic descriptionThe country rocks in the area of this prospect are flyschlike metasedimentary rocks, and stocks, dikes, and sills of Cretaceous feldspar-porphyritic granodiorite and quartz diorite (Berg and others, 1988, p. 16, 18). The strata were regionally metamorphosed to greenschist grade in Late Cretaceous time; their premetamorphic age may be Jurassic or Cretaceous. According to U.S. Bureau of Mines claim records (1977), this prospect, which appears to be in metapelite, near the contact of a granodiorite or quartz diorite stock, was staked for Au. No other information about it has been made public.
