Location: The exact location of placer prospects on Pocahontas Creek is not known. The site is arbitrarily placed in the NE1/4 of section 15, T. 7 N., R. 23 E. of the Kateel River Meridian. The prospects may be in the Melozitna quadrangle.
Geology: Eakin (1916) reported that placer gold prospects had been found on Pocahontas Creek. Panned concentrate samples collected by Kurtak and others (1999) contained moderate amounts of magnetite, but no gold or other ore minerals. The rocks in the Pocahontas Creek area (in the Hughes quadrangle) are Cretaceous, medium-grained hornblende-biotite granodiorite and quartz monzonite of the Indian Mountain pluton (Patton and Miller, 1966). No other information is available on this occurrence.
Workings: Prospecting and surface sampling.
Age: Quaternary.

Commodities (Major) - Au
