|Location and accuracy||Allene Creek, in the eastern Teller B-3 and western Teller B-2 quadrangles, is a north-flowing tributary to North Creek, a south tributary to the Agiapuk River. Placer-mining operations took place along this drainage at surface elevations of about 200 feet and at 260 to 350 feet. Upstream operations were 12 miles east of Brevig Mission. This location includes localities 71, 72, and 73 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Allene Cr.'.|
Geologic descriptionBedrock in the Allene Creek drainage is a chlorite and mica schist assemblage that is locally intruded by small greenstone bodies (Sainsbury, 1972); the age of this assemblage is uncertain but it is probably Paleozoic. Dredge and later dozer/sluice mining took place on the main drainage at about 200 feet surface elevation (Cobb and Sainsbury, 1972) and for 1.5 miles between surface elevations of 260 to 350 feet (Sainsbury and others, 1969). Early mining apparently encountered fine, bright gold on a false clay bedrock but little is recorded about the character of this placer deposit.
