Location: This occurrence is at an elevation of about 1,250 feet on the south valley wall of an east-flowing drainage 3 miles west of Lynn Canal and 5 miles west of Sullivan Island. It is in the NW1/4NW1/4 section 19, T. 33 S., R. 60 E. of the Copper River Meridian. The location is accurate within 1/4 mile.
Geology: This occurrence consists of sulfide-bearing quartz-calcite veins in siliceous argillite. The sulfide minerals are arsenopyrite, chalcopyrite, galena, pyrite, and sphalerite. A sample of one vein collected by the U.S. Bureau of Mines contained 0.1 ppm gold, 1,100 ppm copper, 1,800 ppm lead, and 5,000 ppm zinc (Clough and Redman, 1989). The occurrence is in the Dream prospect area (also see JU009), the site of extensive exploration and mapping from 1987 through 1990 by International Curator Resources Ltd. and Placer Dome U.S. (Bull and others, 1989). The area was covered by 600 federal mining claims in 1989, and more than 5000 feet of drilling was completed by the end of 1990 (Swainbank and others, 1991). The area is underlain predominantly by metamorphosed Silurian and Devonian clastic rocks, limestone, and volcanic units; Permian limestone and siltstone; and small plutons of Tertiary and Cretaceous granodiorite (Brew and Ford, 1985).
Workings: The occurrence is in the Dream prospect area (also see JU009), the site of extensive exploration and mapping from 1987 through 1990 by International Curator Resources Ltd. and Placer Dome U.S. (Bull and others, 1989). The area was covered by 600 federal mining claims in 1989 and more than 5000 feet of drilling was completed by the end of 1990 (Swainbank and others, 1991).
