The Tok Antimony is a antimony 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 (Deposit): Model Name = Stibnite vein (Cox and Singer, 1986; model 27d)
Comment (Geology): Geologic Description = The Tok Antimony deposit, also called Boulder Creek, Stibnite, A Lucky Leak, and Stibnite Creek was discovered in the early 1900's. The mineralization at the prospect consists of a six-meter-wide fault zone that contains four types of stibnite ore: (1) coarse-grained, acicular stibnite in crystals up to 50 millimeters long associated with quartz, (2) fine-grained massive stibnite with interstitial quartz and minor pyrite, (3) mineralized breccia consisting of quartz and schist fragments in a matrix of quartz, calcite, muscovite, stibnite and pyrite, and (4) quartz-pyrite-stibnite stringers. The high-grade ore is concentrated along two well-defined fault planes as two distinct veins about 0.6 meter wide, separated by 1 to 2 meters of fractured and altered chlorite schist. Isolated pods of stibnite and pyrite-bearing quartz stringers less than 1 to 2 centimeters wide occur along minor faults within 30 meters of veins (Ebbley and Wright, 1948).? In 1940, several tons of ore from the prospect were stockpiled by Boulder Creek awaiting transport. All of it was washed away by the river and was never processed (Ebbley and Wright, 1948).
Comment (Reference): Primary Reference = Ebbley and Wright, 1948
Comment (Production): Production Notes = Several tons of high grade ore were stockpiled at the site in 1940, but were washed away by the river before it could be transported (Ebbley and Wright, 1948). There was some mining from an open cut with a bulldozer in 1976 (York, 1980).
Comment (Workings): Workings / Exploration = A 12-foot adit was driven in 1914. In 1940, several tons of material were stockpiled and mined, but were washed away by the river before it could be transported from the deposit (Ebbley and Wright, 1948, p. 31).
