Location: This placer prospect is on Lignite Creek, about 3 miles upstream from its junction with the Nenana River. The map site is near the mouth of Frances Creek, in sec. 3, T. 12 S., R. 7 W., of the Fairbanks Meridian.
Geology: Lignite Creek drains an Eocene to Miocene sequence of poorly consolidated, pebbly sandstone, claystone and subituminous coal. The sequence pinches out northward and is overlapped unconformably by Tertiary Nenana Gravel (Wilson and others, 1998). The southern edge of the Lignite Creek drainage basin is underlain by of Birch Creek Schist. Placer gold has been reported in Lignite Creek near the mouth of Frances Creek. The sources of the gold probably are paleoplacers in the Nenana Gravel.
Workings: Surface workings prior to 1918.
Age: Quaternary.
Commodities (Major) - Au
Development Status: Undetermined.
Deposit Model: Placer Au (Cox and Singer, 1986; model 39a)
