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 (Reference): Primary Reference = This record

Comment (Workings): Workings / Exploration = No workings are present. Only reconnaissance surface geochemical sampling of this occurrence has been completed.

Comment (Geology): Geologic Description = This occurrence consists of an epithermal hot spring deposit containing carbonized fossil plant fragments preserved in siliceous cap rock. Grab samples of the deposit contain as much as 0.24 ppm gold, 1.8 ppm silver, 3 ppm mercury, and 380 ppm lead. The country rocks are largely Jurassic volcanic rocks (Box and others, 1993).

Comment (Geology): Age = Tertiary the preservation of a surface hot spring deposit containing plant fragments suggests that they are Tertiary in age.

Comment (Deposit): Model Name = Hot spring Au-Ag? (Cox and Singer, 1986; model 25a)

Comment (Deposit): Other Comments = This description is from unpublished field notes (station #92AM25) of M.L. Miller, U.S. Geological Survey, Anchorage, Alaska.
