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 = Probably inactive
Comment (Deposit): Model Name = Stibnite along fractures.
Comment (Geology): Geologic Description = The only published information on the site is given by Roehm (1945 [IR 195-37]). Needle-like crystals of stibnite and pyrite occur along fractures in reddish-colored granite. One sample assayed 13.9% Sb and traces of gold and silver . Brew (1997 [OF 97-156-I]) shows a small Cretaceous diorite pluton that extends across Wrangell Narrows at or in the vicinity of this site; the pluton is bordered on the Mitkof side of the Wrangell Narrows by a large Cretaceous hornblende-diorite pluton and on the Woewodski Island it is surrounded by Mesozoic greenstone and greenschist.
Comment (Workings): Workings / Exploration = A prospect little known in the literature and apparently not active since the 1940's.
Comment (Geology): Age = Cretaceous or younger if the stibnite-bearing fractures cut the Cretaceous diorite plutons.
Comment (Reference): Primary Reference = Roehm, 1945 (IR 195-37)
Comment (Production): Production Notes = None
