Location and accuracy The Scott prospect is about 1.4 miles northeast of the east end of Harvey Lake and about 0.3 mile northeast of the center of section 24, T 61 S, R. 79 E. It is in a steep gully at an elevation of about 770 feet. The location is accurate. Figure 20 in Still and others (2002) is a detailed map of the Scott prospect.

Geologic setting

Geologic description

At various times from the 1970s, much of central Woewodski Island has been staked by a succession of companies; these include Resource Associates of Alaska, Cominco Exploration, Colony Pacific, Amselco, Kennecott Exploration, Houston Oil and Minerals, Westmin Resources, and the Olympic Resources Group. During several of these episodes in the 1980s and early 1990s, there was soil sampling on the Scott prospect and three holes were drilled there (Still and others, 2002). It has been examined several times since and claims are still active on it in 2008. The nearby Scott Gold prospect (PE090) shares a similar history.
The Scott deposit can be traced for 300 feet in a series of discontinuous exposures along a steep gully. The mineralization consists of bands and lenses of barite, pyrite, and galena, 0.1 to 2.0 feet thick, that parallel the layering in the host rock. The host rocks at the prospect are semischist and phyllite that are correlative with the Triassic Hyd Group (Karl and others, 1999, Brew, 1997). Individual lenses of mineralization can be traced for to up to 30 feet. Still and others (2002) collected 22 samples that contained up to 1,122 parts per billion (ppb) gold, 47.3 parts per million (ppm) silver, 2.63 percent lead, and 40.9 percent zinc. Lower metal values persist out into the wall rock as disseminated ore minerals and a sample of quartz and greenstone float found near the sulfide lenses contained up to 8,157 ppb gold. (There is no information available on the drill holes.)
