Comments
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 located on state land.
Comment (Workings): Workings / Exploration = This prospect was developed by a 56-foot adit in 1914.
Comment (Reference): Primary Reference = Capps, 1937
Comment (Geology): Geologic Description = This prospect was first described by Brooks (1915) as an auriferious quartz vein developed by a 56-foot-long adit. The vein cuts Cretaceous metasediments, and is said to have a thickness of up to 2 1/2 feet and to carry free gold. No additional information regarding geology, production, or development is available.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Cretaceous or younger
