MAS/MIL number 20760004.
Location: This prospect which has been located as the Caribou 1-59 claims is at an elevation of about 2,250 feet, at the west end of a plateau bounded by Portage Creek, Devils Canyon, and Devil Creek It is 2.8 miles north-northeast of the junction of Portage Creek and the Susitna River in the SW1/4 sec. 17, T. 32 N., R. 1 E., Seward Meridian. The location is accurate to within 1/4 mile. It is locality 8 of Csejtey and Miller (1978).
Geology: The host rock of this prospect is quartz monzonite of Cretaceous or Tertiary age (Richter, 1963) Silicified, fluorite-bearing, shear zones in the quartz monzonite contain lenses, vugs and masses of molybdenite crystals and other sulfides, chiefly pyrite, chalcopyrite, and sphalerite. Channel samples contain up to 0.1 percent molybdenum and 0.1% zinc (Richter, 1963). The mineralization is probably a quartz-monzonite-related porphyry deposit.
Workings: Workings consist of a bench cut and a short adit. Channel samples contain up to 0.1 percent molybdenum and 0.1 percent zinc (Richter, 1963). Further exploration at this locality may be justified but would require heavy equipment or drilling due to poor surface exposure (Richter, 1963).
Age: In Cretaceous or Tertiary rocks.
Alteration: Silicification along shear zones.

Commodities (Major) - Mo; (Minor) - Cu, Zn
