Comments on the geologic information

  • Geologic Description = This site consists of a fracture or shear zone that has been traced for 600-700 feet; it is 3 to 5 feet wide and contains shoots and kidneys of stibnite as much as 4 feet across (Brooks, 1916; B 649). In places the fracture zone appears to have little ore in it and in others the stibnite occupies the entire zone. Between the shoots, quartz and mineralized schists contain small kidneys of ore. The stibnite forms finely granular and fibrous aggregates and shows only a thin film of oxidation products. Fine grains of vitreous quartz occur in the masses of stibnite. Some fractured quartz is cemented by stibnite. Some gold and argentiferous galena are also present. The shear zone is in part bounded by smooth walls and in part by zones of fractured schist. Mica schist country rock strikes N 80 E, and dips 80 S. One sample contained 46.53% Sb and ore samples averaged 0.75 ounces of gold and a trace to 1.96 ounces of silver per ton (Joesting, 1942, ATDM Pamph. 1; Killeen and Mertie, 1951).
