Geologic setting

Geologic description

Gold occurs in a quartz vein in silicified schist; the vein is oriented N 70 E, 35 S (Hill, 1933). The vein varies in width from 6 inches to 22 inches wide (Chapin, 1919; Hill, 1933). Samples assayed $1.04 and $1.24 gold per ton, or 0.05 to 0.06 ounces of gold per ton (Hill, 1933). Two veins, 1/2 to 1 inch wide and 1 to 4 inches wide, contain arsenopyrite and visible gold, they assayed $13.46 and $77.84 per ton (0.65 ounces of gold per ton and 3.77 ounces of gold per ton) (Hill, 1933). A 100 foot adit was driven on the vein with a 65 foot long stope (Chapin, 1919). Production was reported in 1917 and 1918 but the amount is not known (Chapin, 1919; Martin, 1920).
