Location and accuracy Mission Creek is a 35-mile-long tributary that drains into the Yukon River near the town of Eagle. The location of placer gold mining on Mission Creek is uncertain; the mine coordinates are placed about 8 miles upstream of the mouth of the creek, in section 24, T. 1 S., R. 31 E., of the Fairbanks Meridian. The location is only accurate within 8 miles. Mission Creek is locality 22 of Burleigh and Lear (1994), locality 38 of Eberlein and others (1977), and locality 33 of Cobb (1972 [MF-393]).

Geologic setting

Geologic description

Rocks in the valley of upper Mission Creek are Paleozoic quartz-mica schist, greenschist, and local marble that have been intruded by Mesozoic or Tertiary granitic rocks (Foster, 1976). The rocks along lower Mission Creek consists of Late Cretaceous to Pliocene terrigenous sedimentary rocks, Precambrian limestone and greenstone, and minor Mesozoic or Tertiary granitic rocks. There are extensive Quaternary terrace deposits on the lower part of the creek. Heavy-mineral concentrates near the mouth of the creek contain ilmenite, iron oxides, zircon, garnet, anatase, and trace rutile, tourmaline, and monazite (Wedow, 1954).
Mission Creek and its tributaries were prospected in the late 1800s and placer gold was observed in the gravel (Spurr, 1898). Coarse gold was found in many places on Mission Creek as of 1935, but no area had significant grades (Powers, 1935). Mining occurred on Mission Creek prior to 1936, and mining was planned for 1937 (Mertie, 1938). Gold could not be profitably recovered in 1938 (Mertie, 1942). Placer gold-bearing tributaries of Mission Creek include American Creek (EA054), Wolf Creek (EA052), Colorado Creek (EA035), and Excelsior Creek (EA032).
