Location and accuracy This prospect is known only from U.S. Bureau of Mines (1977) claim records. Its approximate location is at an elevation of about 1400 feet, about 0.8 mile inland from the east shore of Clover Passage, and about 1.8 miles due east of the south tip of Joe Island. The site is in section 23, T. 73 S., R. 90 E., of the Copper River Meridian. It corresponds to loc. 44 in Elliott and others (1978). The location is accurate within 0.2 mile.

Geologic setting

Geologic description

The country rocks near this prospect consist mainly of flyschlike metasedimentary rocks, and subordinate andesitic and basaltic metavolcanic rocks that are intruded by Cretaceous stocks, sills, and dikes of feldspar-porphyritic granodiorite (Berg and others, 1988). There also are scattered, small, fault-bounded outcrops of Cretaceous ultramafic rocks. 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 (Brew, 1996, p. 27; Berg and others, 1988, p. 17). The premetamorphic age range of the strata is unknown. Berg and others (1988, p. 17) note that they closely resemble Upper Jurassic to mid-Cretaceous marine flysch and volcanic rocks nearby on Gravina Island.
According to U.S. Bureau of Mines claim records (1977), this prospect, which appears to be in metapelite not far from an ultramafic body, was staked for iron. No other information about it has been made public.
