Comments on the geologic information

  • Geologic Description = Gold is found in quartz veins in a shear zone containing stibnite, arsenopyrite, auriferous tetrahedrite, and galena. Two veins, the Wild Rose and the Soo, trend east and dip north. The Chief vein trends N 50 E and dips 50 NW. The veins contain free gold, some of which is smeared on slickenside surfaces (Smith, 1913; B 525). Gold fineness ranges from 823 to 843 (Smith, 1913; B 525). Much of the ore contained $50 to $60 or more per ton, with some of the richest running over $250 per ton (Smith, 1913; B 525). Hill (1933) reported that typical ore from the H-K vein shows two generations of quartz; one with a little gold and the second with pyrite, arsenopyrite, stibnite and free gold.? the Wild Rose vein contains small bunches of stibnite with a little galena, tetrahedrite, and copper sulfides (Chapin, 1914). Specimens of stibnite consist of columnar and fibrous masses, together with fine granular aggregates (Brooks, 1916; B 649). Specimens of curved and bladed crystals of stibnite contain over 60% Sb (Joesting, 1942; ATDM Pamph. 1).? the mine operated intermittently from 1910 to 1936. Total gold production from 1912 to 1914 and from 1925 to 1931 was between $140,000 and $165,000, or about 7500 ounces (Hill, 1933). Ebbley and Wright (1948, p. 38) reported that antimony ore had been produced.

Comments on the workings information

  • Workings / Exploration = Mine development consisted of several shafts and extensive underground workings, mainly along the Wild Rose vein on the Soo claim (Chapin, 1914).
