Comments on the geologic information

  • Geologic Description = This site is a mineralized shatter zone in schist that is cut by granitic dikes. The lode consisits of quartz and sulfides and their oxidation products. Kidneys of stibnite, some coarsely columnar and some finely granular, are more abundant near the footwall than the hanging wall (Brooks, 1916; B 649). Some of the ore is very rich in gold; production occured from 1910 to 1912 (Brooks, 1911; Brooks, 1912). A shaft, a little more than 300 feet deep was sunk in a vein that dips from 70 degrees at the surface to 45 degrees at the bottom of the shaft, and is as much as 3.5 feet wide (Smith, 1913; B 525). Granitic rock was encountered 50 feet from the shaft in a crosscut into the hanging wall. A decomposed granite dike was encountered in a crosscut on a 300-foot level drift. Grab samples from probable mill ore taken in 1931 assayed 0.07 to 0.14 ounces of gold per ton (Hill, 1933).? Antimony ore was mined in 1916 (Smith, 1917; BMB 153). Some stibnite was produced during World Wars I and II (Mulligan, 1974, p. 11).
