|Location and accuracy||This placer prospect is on lower Sweepstakes Creek near its junction with Peace River. It is in section 28, T. 2 N., R. 12 W., of the Kateel River Meridian. Cobb, 1972 (MF-389), location 44.|
Geologic descriptionThis site was prospected for placer gold during the winter of 1908. Two shafts were sunk on the east bank of the creek. The material on the dump was well-rounded river gravel consisting almost entirely of igneous rocks, some of which were iron-stained. The easternmost of the two shafts was probably no more than 15 feet deep. The other shaft could have been up to 25 feet deep. Another shaft further east on a higher bench was probably 5 to 10 feet deep. The dump material from this shaft consisted of less-rounded gravel and much more mud mixed with the sand. Apparently some gold was recovered from the shafts, but the placer was not rich enough to mine (Smith and Eakin, 1911).
