It is located 4 miles northwest of the Glenn Highway and the Tok River, and about 7 miles west of Clearwater Camp. The location is accurate to within 2 to 3 miles.
Geology: The Noah prospect is a copper prospect in Precambrian and/or Paleozoic quartz-feldspar-biotite gneiss (amphibolite grade) near a Mesozoic or Tertiary pluton (Foster, 1970; MacKevett and Holloway, 1977). No more information is available.
Workings: Surface exploration has been done on the property.
Age: If it is a porphyry-Cu deposit, it is likely to be from one of the three porphyry ages in eastern interior Alaska: 90 to 100 Ma, 70 Ma, or 55 Ma.

Commodities (Major) - Cu
Development Status: None
Deposit Model: Possibly a Cu-porphyry deposit (Cox and Singer, 1986; model 21a)
