Location: The prospect is located in the SE1/4 section 10 T. 2 S., R. 1 E., of the Seward Meridian at an elevation of about 2,500 feet. This prospect occurs nearly a mile east of the head of Thumb Cove on the south side of Spoon Glacier. This is location 100 of Cobb and Tysdal (1980) and location S-190 of Jansons and others (1984). This location is accurate to within half a mile.
Geology: The occurrence is hosted in pillow basalts of the Valdez Group of Late Cretaceous age (Nelson and others, 1985). It consists of a zone of massive magnetite that grades up-dip into massive chalcopyrite (Tysdal, 1978 [MF-880-A]). The occurrence is reported to be traceable to for 4,500 feet along strike (Grant and Higgins, 1909). No other information available.
Workings: No assay results or workings are reported.
Age: Cretaceous or younger; the mineralization is in rocks th Valdex Group of Late Cretaceous age.
Commodities (Major) - Cu, Fe
Development Status: None
Deposit Model: Cyprus massive sulfide (Cox and Singer, 1986; model 24a)
