Location: West side of Barry Arm, 1.3 miles northeast of Peak 3,596 of Mount Doran. Accurate within 0.5 mile. Locality 57 of Cobb (1972) and locality 46 of MacKevett and Holloway (1977).
Geology: Johnson (1914) reported a shattered felsic dike, 60 to 67 inches wide, is cemented by quartz stringers up to 8 inches wide that carry gold, arsenopyrite, galena, and pyrite. The felsic dike is Tertiary in age, and strikes N 50 E, and dips 53-75 W. A nearby 3 ft wide quartz vein strikes N 51 W with a 60 E dip, and contains gold, arsenopyrite, galena, and pyrite in a quartz-calcite gangue. Samples from the dike contain as much as 0.34 oz/ton Au (Johnson, 1914). The felsic dike cuts metasedimentary rocks of the Valdez Group.
Workings: Explored by a limited number of open cuts. Samples from the dike contain as much as 0.34 oz/ton Au (Johnson, 1914).
Age: Tertiary or younger; vein cuts a shattered Tertiary felsic dike.
Production: No known production.
