The Bunker Hill is a gold mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

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).
