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 (Reference): Primary Reference = Christie, 1974

Comment (Workings): Workings / Exploration = None, brief examination

Comment (Geology): Geologic Description = Color anomaly in Unalaska Formation (see Drewes and others, 1961) near contact with diorite(?). Anomaly is a zone containing 2 percent sulfides, 500 feet (150m) by 2000 feet (600 m) in size, elongate to the northwest. Sulfides are dominantly pyrite with traces of chalcopyrite. There appeared to be no structural control on stronger alteration and mineralization.

Comment (Exploration): Status = Inactive
