Location: Davis Creek is a north-flowing tributary to the South Fork, Koyukuk River. The mouth of Davis Creek is about 4.5 miles east-northeast of Gold Bench and 3.5 miles northwest of Grayling Lake. Placer mining has occurred along the lower 0.8 mile of the creek; most of the mining was within a few hundred feet of its mouth. (Little mining was done at the mouth itself as the gravel bars there are typically dry.) The center of mining is a short distance upstream from the mouth of Davis Creek in the NW1/4 of section 17, T. 25 N., R. 13 W. of the Fairbanks Meridian. The location is accurate.
Geology: Thick, washed gravel above the mouth of Davis Creek is cut by the creek channel and contains small amounts of gold (Maddren, 1913). Maddren (1913) reports that a little mining occurred on Davis Creek in the early 1900's. Reed (1938), however, indicates that considerable mining was done then. Davis Creek may have been mined as late as the 1990's (Kurtak and others, 2002). Little mining was done near the mouth as the bars near the mouth are typically dry. The rocks near the mouth of the creek are Paleozoic pelitic schist with subordinate quartzite (Patton and Miller, 1973). A panned-concentrate sample of gravel collected about 0.8 mile above the mouth of Davis Creek contains 6 coarse and 6 fine gold particles; the sample was analyzed and contains 220 ppm gold and 351 ppm bismuth (Kurtak and others, 2002). A sample of a 3-inch-wide quartz vein that cuts micaceous schist on Davis Creek contains 150 ppb gold (Kurtak and others, 2002).
Workings: Maddren (1913) reports that a little mining occurred on Davis Creek in the early 1900's. Reed (1938), however, indicates that considerable mining was done then. Davis Creek may have been mined as late as the 1990's (Kurtak and others, 2002).
Age: Quaternary.
Production: Maddren (1913) reports that about $5,000 in gold (about 250 ounces)was produced from 1900 to 1909.
