The Thompson is a zinc and 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 (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Hummel, 1962 (MF 248)

Comment (Workings): Workings / Exploration = Probably discovered in the World War II era during the search for strategic metals.

Comment (Geology): Age = Probably mid-Cretaceous or younger if a vein occurrence.

Comment (Geology): Geologic Description = The Thompson prospect is a vein or fault-controlled occurrence containing zinc and antimony minerals (Hummel, 1975) that are assumed to be sphalerite and stibnite. The prospect is near or at the upper contact of calcareous schist with a marble layer; the rocks strike northwest and dip northeast (Hummel, 1962 [MF 248]). The Thompson prospect is one of several of diverse type and metal content in the general vicinity of Rocky Mountain Creek, Nelson Gulch, and Christian Creek.

Comment (Deposit): Model Name = Vein (?) occurrence of antimony and zinc minerals in calcarous metasedimentary rocks.
