Location and accuracy At least two miles of Fox Creek has been mined; part is in the Fairbanks quadrangle, part is in the Livengood quadrangle. Most of the mining or at least the mining since WWII, has been in the Livengood quadrangle. But much of the information of record about placer mining on Fox creek cannot be assigned to one of the quadrangles, For convenience, all of the information on Fox Creek has been consolidated into this record. This site is about 3.0 miles north of Fox in section 18, T. 2 N., R. 1 E. The location is accurate.

Geologic setting

Geologic description

Placer gold was being mined from Fox Creek by 1908 (Prindle, 1908; Prindle and Katz, 1913). There is little record of the early mining but it is likely that prior to WWI, much if not all of Fox Creek was prospected and staked and mining took place at various places along it. In 1914, Mr. Ardvino located the Vino Bench and Vino claims near the head of Fox Creek and mined there until 1935 (Cornelius and Madonna, 1988). In 1985, Tillicum Mining acquired the property and in 1987 mined at the head of Fox Creek on what they considered an eluvial or residual placer (Cornelius and Madonna, 1988). Much of the gold was angular and intergrown with rusty quartz. In subsequent years, the upper mile or more of upper Fox Creek was mined and reclaimed (Janet Schaefer, field observation, 1999). Szumigala and others (2011) report that Tillicum Mining and three other operations had produced gold from open pit mines on Fox Creek in 2010. Satellite imagery available on the internet suggests that a bare area on lower Fox Creek in about the middle of section 30, T. 2 N., R. 1 E. (in the Fairbanks quadrangle) may be one of those mines.
Early studies report that the depth to bedrock on Fox Creek was 10 to 19 feet, and that granite is exposed near the head of the creek (Prindle and Katz, 1909; Prindle and Katz, 1913). Bedrock in the Fox Creek drainage is mainly quartz-muscovite schist, quartzite, and chlorite-quartz schist, which is intruded by Cretaceous granite, tonalite, and quartz diorite at the head of the creek (Newberry and others, 1996). Placer concentrates near the head of the creek contained an estimated 90 percent scheelite (Joesting, 1943; Byers, 1957.
About 1,500 ounces of gold was produced from Fox Creek from 1905 to 1910 (Prindle and Katz, 1913). Production figures for more recent mining are not available in the public record.
