Location and accuracy This prospect is known only from U.S. Bureau of Mines (1977) claim records. Its approximate location is at or near sea level about midway along the northwest shore of Coon Cove. The site is in section 7, T. 74 S., R. 92 E., of the Copper River Meridian. It corresponds to loc. 49 in Elliott and others (1978). The location probably is accurate within 0.2 mile.

Geologic setting

Geologic description

The country rocks near this prospect are mainly gray pelitic phyllite and subordinate andesitic or basaltic metavolcanic rocks that are intruded by Cretaceous stocks, sills, and dikes of feldspar-porphyritic granodiorite, and by small metadiorite plutons of undetermined age (Berg and others, 1988). The strata were regionally metamorphosed to greenschist-grade phyllite and semischist in Late Cretaceous time, and, near some of the granodiorite contacts, subsequently contact metamorphosed to hornblende hornfels (Berg and others, 1988; Brew, 1996, p. 27). The premetamorphic age of the metapelite-metavolcanic unit is unknown. Berg and others (1988, p. 17) noted its resemblance to Upper Jurassic to mid-Cretaceous marine flysch and volcanic rocks on Annette and Gravina islands, but assigned it an undivided Mesozoic or Paleozoic age. Near Coon Cove it structurally overlies faunally-dated Permian and Triassic rocks.
According to U.S. Bureau of Mines claim records (1977), this prospect, which appears to be in metapelite that probably is intruded by granodiorite sills and dikes, was staked for Cu, Pb, and Zn. No other information about it has been made public.
