Location: TheNay Nadeli placer gold deposit is on a west-flowing tributary of upper Wickersham Creek. The area of placer activity extends from the mouth of the tributary, upstream to the map site, which is in the SW1/4 of sec. 1, T. 21 S., R. 1 W., of the Fairbanks Meridian. This is location B-5 of Balen (1990: 34-90).
Geology: This tributary of Wickersham Creek drains an area underlain by Tertiary or Cretaceous granodiorite, quartz monzonite and granite, and by Cretaceous or Jurassic turbidites (Wilson and others, 1998). The placer gold was probably derived from the erosion of auriferous lodes, such as those at HE172 and HE178. Placer samples collected by the BLM contained 0.0053 ounce of gold per cubic yard (Kurtak and others, 1992).
Workings: Surface workings date from the early 1900s.
Age: Quaternary.
Production: There was very small production of gold in the early 1900s.
