The Black Mountain is a antimony, silver, and 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.

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 (Geology): Age = Cretaceous or Tertiary . The vein crosscuts clastic sedimentary rocks that may range in age from lare Paleozoic to mid-Cretaceous (Bundtzen and Laird, 1991). The nearby granitic rocks may be Cretaceous or Tertiary.
Comment (Workings): Workings / Exploration = Cady and others (1955) reported that claims have been staked on the prospect. Some small pits or trenches are probably present.
Comment (Reference): Primary Reference = Ebbley and Wright, 1948
Comment (Deposit): Model Name = Simple Sb deposits (Cox and Singer, 1986; model 27d)
Comment (Geology): Geologic Description = A single, 2-inch wide, stibnite-bearing vein in shaly sandstone was traced for a distance of 200 feet at this location (Ebbley and Wright, 1948). The vein trends subparallel to the contact between clastic sedimentary country rocks and a granitic stock upslope to the north of the vein (Ebbley and Wright, 1948; Hoare and Coonrad, 1959). Host rocks to the vein are not altered, and only one vein has been identified at this prospect. A sample collected along 50 feet of the vein contained 48.9 percent antimony, 0.02 ounce of gold per ton, and 0.2 ounce of silver per ton (Ebbley and Wright, 1948). The sedimentary rocks may either be part of the mid-Cretaceous Kuskokwim Group (Hoare and Coonrad, 1959), or possibly an upper Paleozoic or Mesozoic section correlative with parts of the Gemuk Group (Bundtzen and Laird, 1991). The nearby granitic rocks may be part of a Cretaceous or Tertiary igneous assemblage that is widespread through southwest Alaska.
