Location: The occurrence is located in the NE1/4 section 30, T. 1 S., R. 2 E., of the Seward Meridian. It is situated on the east side of an unnamed stream that flows south from an outlier of Godwin Glacier and is at an elevation of about 1,400 feet. This is location 95 of Tysdal (1978 [MF-880-A]) and location S-192 of Jansons and others (1984). This location is accurate to within a quarter of a mile.
Geology: The occurrence is a thin iron-stained zone containing disseminated sulfide minerals in a medium-grained gabbro. The zone contained 100 ppm copper, and 2,000 ppm vanadium ( Tysdal, 1978 [MF-880-A]). Bedrock in this area belongs to the Resurrection Bay Ophiolite complex, which is included in the Valdez Group of Late Cretaceous age (Nelson and others, 1985). No other information is reported in the literature.
Workings: A single sample contained 100 ppm copper and 2,000 ppm vanadium (Tysdal, 1978 [MF880-A]). No workings or improvements are reported in the literature.
Age: Cretaceous or younger; the mineralization is in rocks of the Valdez Group of Late Cretaceous age.

Commodities (Major) - Cu, V
Development Status: None
Deposit Model: Cyprus massive sulfide (Cox and Singer, 1986; model 24a)
