Location: 2,000 ft east of the eastern shore of Kadin Lake. Accurate within 1,000 ft. This is locality A-2 of Jansons and others (1984).
Geology: Two felsic dikes having chalcopyrite, galena, and sphalerite present in shears. Arsenopyrite occurrs within 1/8 inch veinlets in a 15 ft wide felsic dike (Jansons and others, 1984). The felsic dikes intrude sandstone, siltstone, and mudstone of the Tertiary Orca Group. The chip samples contained 370 ppm to 2.85 percent Zn, 205 ppm to 0.7 percent Cu, 4.4 ppm to 22 ppm Ag, 200 ppm to 0.22 percent Pb, and 72 ppm to 16.5 percent As (Jansons and others, 1984).
Workings: Development has included an 80 ft long tunnel and open pits. Chip samples contained 370 ppm to 2.85 percent Zn, 205 ppm to 0.7 percent Cu, 4.4 ppm to 22 ppm Ag, 200 ppm to 0.22 percent Pb, and 72 ppm to 16.5 percent As. Low mineral development potential (Jansons and others, 1984).
Age: Paleocene or younger; the veins cut felsic dikes which intrude sandstone, siltstone, and mudstone of the Tertiary Orca Group.
Production: No reported production.
Reserves: Inferred reserves are 350 tons at 2.27 percent Zn (Jansons and others, 1984).
Commodities (Major) - Ag, As, Cu, Pb, Zn
Development Status: None
Deposit Model: Chugach-type low-sulfide Au-quartz vein ? (Bliss, 1992; model 36a.1 ?)
