Location: Popovich Creek is a south-flowing tributary to Lignite Creek. Placer gold has been reported along the lower course of Popovich Creek for a distance of 1.5 miles. The map site is about 0.3 mile upstream from the mouth of the creek, in sec. 36, T. 11 S., R. 7 W., of the Fairbanks Meridian.
Geology: Popovich Creek drains an area underlain by Eocene to Miocene, poorly consolidated, pebbly sandstone, claystone, and sub-bituminous coal. These strata pinch out northward and are overlapped unconformably by Tertiary Nenana Gravel (Wilson and others, 1998). Parts of Popovich Creek also flow over inliers of Keevy Peak Formation. The most probable sources of the placer gold in Popovich Creek are Tertiary paleoplacers in the Nenana Gravel.
Workings: Surface workings.
Age: Quaternary.

Commodities (Major) - Au
Development Status: Undetermined.
Deposit Model: Placer Au (Cox and Singer, 1986; model 39a)
