Comments
Comment (Exploration): Status = Inactive
Comment (Workings): Workings / Exploration = The Bunker Hill mine consists of a 102-foot-deep shaft with short drifts on the 25-foot and 60-foot levels (Hill, 1933, p. 154).
Comment (Production): Production Notes = Eight tons of gold ore with an average grade of 1.625 ounces of gold per ton were milled from a gold-quartz vein at the mine (Chapin, 1914 [B 592-J, p. 345]; Hill, 1933, p. 154).
Comment (Deposit): Model Name = Schist-hosted gold-quartz vein
Comment (Geology): Geologic Description = Eight tons of gold ore with an average grade of 1.625 ounces of gold per ton was milled from a gold-quartz vein at the Bunker Hill mine (Chapin, 1914 [B 592-J, p. 345]; Hill, 1933, p. 154). The vein is oriented N. 15 W., 70 E.; it has an average width of 12 inches at the surface, narrowing to 2 inches at a depth of 50 feet (Hill, 1933, p. 154). A grab sample of ore from the dump assayed $24.06 in gold per ton (1.164 ounces of gold per ton) (Hill, 1933, p. 154). Material on the dump consists of mica schist from the hanging wall and blocky quartz-mica schist from the footwall (Hill, 1933, p. 154). Bedrock in the area is Fairbanks Schist, that consists of quartz-muscovite schist, quartzite, and chlorite-quartz schist (Newberry and others, 1996).
