|Location and accuracy||The coordinates are at about the center of a block of 26 claims staked near the south end of Steamer Bay in 1972 and held through 1973. The center is about 0.4 mile north of the center of section 24, T. 65 S., R. 82 E.|
Geologic descriptionA block of 26 claims was staked in 1972 near the south end of Steamer Bay and they were active through 1973; apparently they have not been active since (U.S. Bureau of Mines, 1980; Still and others, 2002). Rocks in the area consist of massive and pillowed greenstone, pillow breccia, and tuff of the Seymour Canal Formation of Jurassic and Cretaceous age (Brew, 1997 [OF 97-156-A]; Karl and others, 1999). Still and others (2002) traversed two streams for a short distance but did not find any outcropping mineralization. They collected two float samples , the best of which, a piece of silicified breccia, contained 10.9 parts per million (ppm) silver, 1,408 ppm copper, 1.01 percent lead, and 1.9 percent zinc.
