Location and accuracy This placer mine is located close to the boundary of sections 22 and 27, T. 7 N., R. 1 W., of the Seward Meridian. The mined area is a bench on the north side of the creek about half a mile east of its junction with Mills Creek. This is location P-77 of Jansons and others (1984). This location is accurate to 300 feet.

Geologic setting

Geologic description

Juneau Creek occupies a narrow avalanche-debris-filled glacial valley. A thick bench deposit consisting of glacial till and poorly washed glacial-fluvial gravel occurs just above the junction with Mills Creek. The pay streak was reported to occur near the top of the old hydraulic cut in the bench (Jansons and others, 1984). The gravels in the cut are tightly cemented with clay, and the gold is very fine (Jansons and others, 1984). Bedrock in this area is Valdez Group slate and graywacke of Late Cretaceous age (Nelson and others, 1985). No assay results are reported.
