Goat

The Goat is a silver, gold, and copper 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 (Workings): Workings / Exploration = Channel samples of the veins assayed up to 0.8 ppm Au and 3 ppm Ag.

Comment (Exploration): Status = Inactive

Comment (Deposit): Model Name = Polymetallic veins

Comment (Deposit): Other Comments = Goat: 2 claims staked in 1969-70. Claims were active in fall of 1973.? Cub: 28 claims staked in 1969-70. Claims were active in fall of 1973.? Berg and others (1977, p. 40-41, 70, 72-72) and Elliott and Koch (1981, loc. 18b) link the Cub group of 28 claims to the Goat group of 2 claims, but only the Goat group is described.? Site is in Misty Fiords National Monument.?

Comment (Reference): Primary Reference = Berg and others, 1977

Comment (Geology): Geologic Description = The country rocks in the general area of this site are graywacke hornfels and argillite of the Jurassic or older Mesozoic Hazelton Group (Berg and others, 1977, p. 15-17 and plate 1; Koch, 1996). ? At the Goat prospect (Berg and others, p. 40-41, 114-115; Elliott and Koch, 1981, loc. 18a), quartz-calcite veins up to 6 inches thick in banded graywacke hornfels locally contain abundant pyrrhotite and minor chalcopyrite. The metagraywacke also contains small amounts of pyrrhotite. Channel samples of the veins assay up to 0.8 ppm Au and 3 ppm Ag. Chip samples of the pyrrhotite-bearing metagraywacke contain only traces of valuable metals.? A geologic description of the Cub prospect was not publicly available at the time of a U. S. Geological Survey field investigation in 1973 (Berg and others, 1977), but its geologic setting is probably similar to that at the Goat prospect.
