Comments on the geologic information

  • Geologic Description = The Stibnite mine began producing ore as early as 1915 (Brooks, 1916 [B 642-A, p. 29]). Stibnite occurs in a shear zone as lenses, kidneys, and in granulary aggregates with some columnar masses; it is associated with iron-stained quartz veins and fragments of schist (Brooks, 1916 [B 649, p. 38-39]; Killeen and Mertie, 1951, p. 14-15). The shear zone trends N. 17 W. and dips 70-89 S.; the stibnite lenses pitch north (Killeen and Mertie, 1951). The largest lens of stibnite reported was 100 feet long, 7 feet wide, and 4 feet thick (Killeen and Mertie, 1951). In 1915 and 1926, about 300 tons of ore were produced from these large stibnite masses (Ebbley and Wright, 1948, p. 38; Killeen and Mertie, 1951). Shipments in 1915 contained 51.5 percent antimony (Killeen and Mertie, 1951). Killeen and Mertie considered the deposit to be mined out in 1951.
