Comments on the geologic information

  • Geologic Description = Gold was found in a 12- to 13-foot-wide vertical shear zone striking N 40 E; it contained highly fractured quartz. Mineralization is along the margin of the vein and along fragments of schist in the vein (Prindle, 1910, p. 227).? the original prospect consisted of three claims: the Lemon, Lime and North Star claims (Prindle, 1910). By 1909, a 120-foot-long adit had been driven parallel to the shear and a cross-cut had intersected the shear zone approximately 50 feet below surface. Samples collected from the site panned $40 gold per ton in free gold (1.9 ounces of gold per ton); they were from the six-inch-wide, high grade portion of the shear. The remainder panned approximately $2 gold per ton in free gold (0.09 ounces of gold per ton) (Times Publishing Company, 1912). Two other parallel quartz-bearing shear zones were known to exist but had not been explored in 1909. Smith (1913, B 525) reported the prospect was inactive in 1912 by which time the adit was 150 feet long (Times Publishing Company, 1912). By 1913 the adit had been extended to 160 feet in length and several cross-cuts driven to explore the shear zone (Brook, 1914).
