Location and accuracy The Jump Creek placer mines on lower Jump Creek approximately one mile upstream from its confluence with Candle Creek. Areas mined on Jump Creek extend west onto the Bendeleben D-1 quadrangle. The map site is in section 26, T. 6 N., R. 16 W., of the Kateel River Meridian. Cobb, 1972 (MF-389), location 18.

Geologic setting

Geologic description

Jump Creek was the placer gold discovery site which opened up exploration in the Candle Creek drainage. Both bench and stream placer deposits are found on on the creek. The creek gravels range from 12 to 18 feet thick and are covered by 10 to 20 feet of tundra. Gravels in bench deposits are 4 to 10 feet thick and are overlain by 5 to 10 feet of tundra. All of the ground is permanently frozen. Bedrock is early Paleozoic quartz-mica schist (Gault and others, 1953). See Candle Creek (ARDF number BN074, Hudson, 1999) and Jump Creek (ARDF number BN070, Hudson, 1999) in the Bendeleben quadrangle for additional information.

Production and reserves

Workings or exploration Gold has been mined fairly continuously from the early 1900s through 1945 by drifting, hydraulicking and dredging. Keewalik Mining operated a dredge near the mouth of the creek in the early 1930s. Small-scale mining and prospecting has been done from the 1950s through the 1980s.
Indication of production Yes; small
