The location of placer gold mining on Boundary Creek is not reported; the coordinates are placed at the approximate midpoint of the creek ,in section 5, T. 3 S., R. 33 E., of the Fairbanks Meridian. Boundary Creek is locality 6 of Eberlein and others (1977) and locality 17 of Burleigh and Lear (1994).

Geologic setting

Geologic description

The rocks in the vicinity of Boundary Creek are undifferentiated Paleozoic greenschist-facies and lesser amphibolite-facies rocks, including schist, greenstone, and local marble, and minor Paleozoic or Mesozoic serpentinite (Foster, 1976). The pay streak on Boundary Creek is reported to be 10 miles long, but recovery in the early 1900s was hampered by large boulders and gravel that had to be removed to reach bedrock (Powers, 1935). The gold is coarse and sold for $18 per ounce (Powers, 1935). The placer gold contained 850 parts of gold and 145 parts of silver per thousand (Mertie, 1942). Smith (1941 [B 910-C]) reported a gold assay from Boundary Creek of 850 parts of gold per thousand.
Placer gold on Boundary Creek was discovered around 1891 (Powers, 1935). Brooks (1903) reports mining on Boundary Creek in 1902.
