Janson and others (1984) could not locate the occurrence described by Roehm in 1938. However, placer gold and sufides occur in the vicinity.
Location: Northwest of Mount Doran, near toe of Toboggan Glacier. Accurate within 2,000 ft (?). Locality A-36 of Jansons and others (1984).
Geology: A quartz vein reportedly occurs between two felsic dikes in Late Cretaceous Valdez Group black slate and metasandstone. The vein is 30 inches wide, traceable for 600 ft, and contains pyrite, arsenopyrite, chalcopyrite, and galena (Roehm, 1938).
Workings: Unknown
Age: Late Cretaceous or younger; vein occurs between two felsic dikes in black slates and metasandstones of the Late Cretaceous Valdez Group.
Commodities (Major) - Au (?)
Development Status: None
Deposit Model: Chugach-type low-sulfide Au-quartz veins (Bliss, 1992; model 36a.1)
