Comments on the geologic information

  • Geologic Description = Gold has been produced from a steeply dipping quartz vein that is two feet thick and contains arsenopyrite, stibnite, and visible gold. The vein strikes northeast and dips steeply northward (Davis, 1922, p. 59; Chapman and Foster, 1969, p. D18). One hundred and twenty-five tons of ore were mined from short drifts off a 60-foot shaft; the ore reportedly ran $30 in gold per ton (about 0.048 ounce of gold per ton) (Davis, 1922, p. 59-60).
