Geologic information

Identification information

Deposit ID 10307614
Record type Site
Current site name Suzie Mountain

Geographic coordinates

Geographic coordinates: -161.65268, 58.95925 (WGS84)
Relative position This prospect is on the west ridge of Suzie Mountain and along the west side of Suzie Creek. The map site is on the ridge crest at an elevation of about 900 feet and about 3.5 miles northeast of Goodnews Mining Camp. It is in the NE1/4 of section 20, T 14 S, R 74 W, of the Seward Meridian. The prospect is accurately located. Cobb's locality number 2 (1972 [MF 362]; 1980 [OF 80-909]) appears to be at this location.

Comments on the geologic information

  • Geologic Description = This prospect is on the west ridge of the Suzie Mountain ultramafic complex, a composite dunite, peridotite, and clinopyroxenite pluton that is inferred to be Jurassic in age (Hoare and Coonrad, 1978; Alaska Earth Sciences, 2000). A geochemical survey in the area of this prospect has defined a 700-meter-long and up to 100-meter-wide soil anomaly that averages 130 ppb Pt; the maximum Pt value in the anomaly is 345 ppb Pt (Alaska Earth Sciences, 2000). The anomaly extends northwest from Suzie Creek across the ridge crest at this locality. On June 1, 1972, Allen L. Clark (U. S. G. S.) told E. H. Cobb (1972 [MF 362]; 1980 [OF 80-909]) that copper minerals had been found at this locality. In the Salmon River area, traces of chalcopyrite, pyrite, or pyrrohotite are common in surface outcrops of hornblende-bearing rocks in marginal parts of the ultramafic complexes (Alaska Earth Sciences, 2000).
  • Age = Jurassic, the inferred age of the ultramafic plutons in the area (Hoare and Coonrad, 1978).

Economic information about the deposit and operations

Development status Prospect

Comments on exploration

  • Status = Active

Mining district

District name Goodnews Bay

Comments on the workings information

  • Workings / Exploration = There has been surface soil and rock sampling at this location (Alaska Earth Sciences, 2000). An aeromagnetic survey was flown over the Salmon River area in 1994, a gravity survey has been completed, and some controlled-source audio magneto-telluric lines have been run over selected parts of the ultramafic complexes (Alaska Earth Sciences, 2000).
