Champion Creek Prospect, Fortymile District, Southeast Fairbanks Borough, Alaska, USA
Location: Champion Creek is a 20-mile-long east tributary of the North Fork of the Fortymile River. The location of prospecting on Champion Creek is not reported; the coordinates are arbitrarily placed about 5 miles upstream of the mouth of the creek, in section 29, T. 4 S., R. 29 E., of the Fairbanks Meridian. Champion Creek is locality 23 of Burleigh and Lear (1994).
Geology: The rocks along the lower half of Champion Creek consist predominantly of Paleozoic quartz-mica schist and greenschist; along the upper portions of the creek, the rocks are mostly Paleozoic biotite schist, quartzite and marble that have been intruded by Tertiary or Mesozoic granitic rocks (Foster, 1976). Quaternary terrace deposits are present along the lower portion of Champion Creek. Powers (1935) reported that miners prospecting for placer gold on Champion Creek found low-grade pay. The Champion I (EA048), Champion II (EA049), East Champion (EA047), and North Champion (EA046) prospects are base-metal and gold lode prospects in the Champion Creek drainage.
