Report: The Copper State is located several hundred ft west of an ephemeral tributary to Sawmill Creek. The site consists of the Duke, Mammoth, Byron, and Mary Rose patented claims. The mine workings consisted of four shafts. The main shaft on the Duke claim was reported to be 200 ft deep; the other shafts were shallow (Roby 1950). The vein consists of quartz and calcite and occupies a steeply dipping fissure in thin-bedded Belt shales. The vein is reported to be 1 to 14 ft wide. Ore on the dump at the Duke shaft consists of dark sphalerite, or possibly marmatite, with some galena and a little chalcopyrite. Oxidized copper minerals also are present. A U.S. Bureau of Mines sample collected from an ore bin assayed 0.01 oz/ton gold, 0.33 oz/ton silver, 31.0 % zinc, 5.9 % lead, and 0.8 % copper. A Bureau of Mines sample from dump at the Duke shaft assayed a trace of gold, 0.2 oz/ton silver, 6.85 % zinc, 0.9 % lead, and 0.3 % copper (Roby 1950). The mine operated sporadically from 1920 to 1927. Two small shipments of sorted zinc ore were made to a custom mill in Salt Lake City, Utah (Roby, 1950). The site is also described in Dahl (1971). The site was visited in June 1998 by the MBMG, and no environmental or safety hazards were noted. Location: CDBB sec. 15, T11N, R8E.
