Location and accuracy Short Creek is a 2-mile-long northwest-flowing tributary of Long Creek. Placer deposits extend about 1 1/2 miles from the head of Short Creek down to the winter trail marked on the Ruby (B-6) Quadrangle (USGS topographic map, 1952). Coordinates given correspond to location 15 of Cobb (1972 [MF405]), and mark the approximate midpoint of the mined area in section 17, T. 13 S., R. 17 E. of the Kateel River meridian. The location is accurate.

Geologic setting

Geologic description

The bedrock underlying the head of Short Creek is intermediate to mafic intrusive rocks, probably greenstone (Puchner and others, 1998). At the winter trail crossing of Short Creek there is 4 to 6 feet of gravel beneath 6 to 8 feet of muck, and the depth to bedrock increases to 75 feet at the mouth of the creek (Mertie and Harrington, 1916; Chapman and others, 1963). The most gold is usually found within a foot of bedrock in an irregular and poorly defined channel (Mertie and Harrington, 1916). The gold is accompanied by cassiterite, and a few thousand pounds of cassiterite were recovered as byproduct in 1918 (Chapin, 1919).
The creek was mined using open-pit methods in 1914 and 1915 (Mertie and Harrington, 1916). The placer ground was worked 10 to 15 feet deep over a width of 20 to 40 feet for a distance of 1 to 1 1/2 miles (Eberlein and others, 1977).
Mining may have extended into the early 1920s, but there are no records of more recent activity (Eberlein and others, 1977).

Production and reserves

Workings or exploration Short Creek experienced open-pit mining during 1914 and 1915 and probably into the early 1920s (Mertie and Harrington, 1916).
Indication of production Yes; small
Production notes The gold is accompanied by cassiterite, and a few thousand pounds of cassiterite were recovered as byproduct in 1918 (Chapin, 1919).
