The Sonny Jim Group is a lead, copper, gold, and silver 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.

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 = Roehm, 1936, 131-4
Comment (Deposit): Model Name = Chugach-type low-sulfide gold-quartz vein (Bliss, 1992; model 36a.1), turbidite-hosted gold vein.
Comment (Deposit): Other Comments = Site is in Kodiak National Wildlife Refuge.
Comment (Geology): Geologic Description = Three lenses and a few small veins of quartz, cutting Cretaceous metasedimentary rock, are exposed on the beach along a narrow lagoon. One lens on the west side of the lagoon ranges from 3 to 10 inches thick and is exposed for 200 feet. It strikes N. 75 W. and dips 85 south. Four parallel quartz stringers dip towards the vein at a distance of 50 to 100 feet. A second lens, located at the south end of the lagoon is 26 to 30 inches in thickness. It strikes N. 65 E. and dips 71 north. The third lens, located on the west side of the lagoon is 6 feet in thick and can be traced for 300 feet. The lens strikes N. 70 E. and dips 73 north. These lenses and stringers were sampled by Roehm (1936, PE 131-4) and assayed only trace amounts of precious metals.
Comment (Workings): Workings / Exploration = Showings were exposed by open cuts at the time of Roehm's visit. Samples assayed only trace amounts of precious metals.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Cretaceous or younger
