Location: Tomboy Creek is an old name for a north tributary of Fairview Creek (NM007); this name is not shown on the current USGS topographic map of the area. The confluence of Tomboy Creek and Fairview Creek is about 4 miles above the mouth of the Fairview Creek on a coastal lagoon along the the Bering Sea. The mine location is 0.6 miles upstream of the mouth of Tomboy Creek and about 4.5 miles southwest of where the Nome-Teller road crosses the Feather River. The mine is locality 1 of Hummel (1975) and locality 58 of Cobb (1972 [MF463], 1978 [OFR 78-93]).
Geology: Placer gold mining took place on Tomboy Creek in 1902; the U.S. Geological Survey obtained pans of about 1.5 cents or 2.25 dollars per cubic yard from decomposed schist bedrock (Collier and others, 1908, p. 219). The overlying several feet of gravel contains numerous pebbles and cobbles of granitic bedrock reworked from glacial deposits that originated in the Kiglauik Mountains. The source of the gold is unknown. The area to the north of the mine is extensively covered by glacial deposits. Near the mine, Sainsbury, Smith, and Kachadoorian (1972) mapped a strong northwest-trending fault, which separates graphitic schist to the south from chloritic, metavolcanic rocks near this mine.
Workings: Surface workings only; small-scale mining by hand in 1902.
Age: Quaternary.
