Location and accuracy The Smallwood Creek mine is located in about the center of T. 1 N., R. 2 E., Fairbanks Meridian. The coordinates are for prospects shown on the Livengood D-1 NW, topographic map. The site is about 4 miles upstream from its mouth on the Little Chena River and about 4.8 miles south of Gilmore Dome. This mine is locality 60 of Cobb (1972 [MF 410]).

Geologic setting

Geologic description

The headwaters of Smallwood Creek are in Cretaceous granite and granodiorite, and the middle and lower sections are underlain by mica schist of the Fairbanks Schist (Newberry and others, 1996). The placer ground is deep, ranging from about 40 feet near the head of the creek increasing downstream to more than 300 feet (Cobb, 1976, OFR 76-662, p. 135). Productive gravels were reported to be 120 feet wide and 3 to 4 feet thick (Prindle and Katz, 1913, p. 103). Mining was reported from 1907 to 1916 and in 1927 (Cobb, 1976 [OFR 76-662]). By 1908, it was reported that prospecting and some production had taken place for several years on Smallwood Creek. Production was $12,000 by 1908, with the gold valued at $18.11 per ounce (Brooks, 1908 [B 345, p. 41-42]; Prindle and Katz, 1913, p. 112-113). Small placer mining operations were active in recent years and may be continuing. The gold was between 878 and 911 fine (Glover, 1950).

Production and reserves

Workings or exploration By 1908, it was reported that prospecting and some production had taken place for several years on Smallwood Creek. Production was $12,000 by 1908 with the gold valued at $18.11 per ounce (Brooks, 1908 [B 345, p. 41-42]; Prindle and Katz, 1913, p. 112-113). Small placer mining operations were active in recent years and may be continuing.
Indication of production Yes; small
Production notes Production figures are not available for recent work on the creek. The only production that has been reported is from Prindle and Katz (1913, p. 112-113), who reported that production as of 1908 was worth $12,000, with the gold valued at $18.11 per ounce.
