The Unnamed (near head of Annette Bay) is a copper 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 (Deposit): Model Name = Probably a lode deposit.
Comment (Geology): Geologic Description = The country rocks near the head of Annette Bay are recrystallized, Upper Jurassic or Cretaceous andesitic or basaltic flows and tuff, and a stock of quartz metadiorite that may be cogenetic with some of the volcanic rocks (Berg, 1972 [I 684]; Karl, 1992). The rocks were regionally metamorphosed to greenschist-grade phyllite and semischist in Late Cretaceous time. The site has been described only as a reported occurrence of antimony and copper minerals (Berg and Cobb, 1967, p. 180).
Comment (Reference): Primary Reference = Berg and Cobb, 1967
