Location and accuracy The PT claims are at an elevation of about 500 feet, about 1.3 miles southeast of Cube Point on Admiralty Island. The claims are 0.3 mile northeast of the sec. 20 numeral, in T. 45 S., R. 66 E. They are MAS no. 0021140038 (U.S. Bureau of Land Management, 2002). The location probably is accurate within 0.2 mile.

Geologic setting

Geologic description

The rocks in the vicinity of this prospect are part of the Devonian Retreat Group which consists of schist with marble interbeds (Lathram and others, 1965). The only information about this prospect is that one or more claims were staked here for copper, lead, and zinc by WGM, Inc. (U.S. Bureau of Land Management, 2002). Although there is scant information on this prospect, it may be in the same age of rocks as the nearby Greens Creek Mine (Barnett and Miller, 2003; ARDF JU253).
