Köppen climate type:
Placer genesis and lode source poorly known (Eberlein and others, 1977).
Location: Moose Creek is a 1.5-mile-long, southwest-flowing tributary of Poorman Creek. Site coordinates corresponding to location 36 of Cobb (1972 [MF405]) are given for the approximate midpoint of placer ground in the lower part of the Moose Creek valley, in section 7, T. 17 S., R. 16 E., Kateel River Meridian. The location is accurate within a quarter mile.
Geology: The headwaters of Moose Creek drain deeply weathered basaltic greenstone (Cass, 1959; Mertie, 1936). Stream gravels are greenstone with considerable vein quartz (Mertie, 1936). The gold along Moose Creek is found in old channels that lie under the southwest valley slope (Mertie, 1936). The present stream follows the northwest side of the asymmetrical valley. The pay streak was about 50 to 60 feet wide, buried by about 55 feet of muck, and ran about 40 cents per square foot of bedrock (gold at $20.67 per ounce). Some richer areas were reported to run $3 to $5 per square foot of bedrock (Mertie, 1936). The gold is fairly fine grained and well-rounded, but one 7-ounce nugget was reported (Mertie, 1936). One assay showed 842.5 parts gold per thousand and 152 parts silver per thousand. Gold was first discovered along Moose Creek in 1920, but the pay streak was not located until 1931 (Cobb, 1973 [B1374]). The old channel was mined extensively from shafts and drifts. Some gold was produced from the creek from 1931 through 1939 (Eberlein and others, 1977).
Workings: Shafts were sunk 50 to 60 feet to bedrock for drift mining from 1931 through 1939. Old stream channels were mined extensively from shafts and drifts (Eberlein and others, 1977).
Age: Quaternary.
