Location: This occurrence is at an elevation of about 1,500 feet, 1.7 miles west of the summit of Tukgahgo Mountain. It is in the south-central part of section 5, T. 30 S., R. 57 E. of the Copper River Meridian. It is shown as mineral occurrence 7 on sheet 1 of Redman and others (1984) and as number S048 by Wells and others (1986).
Geology: Redman and others (1984) describe this occurrence as a series of chalcopyrite-bearing quartz veins that cut a diorite dike in metabasalt. The veins are 1 to 10 inches thick and at least 35 feet long. A representative sample contained 520 ppm copper and 0.3 ppm silver. The diorite dike is probably the same age as the nearby mid-Cretaceous, Mount Kashagnak pluton.
Age: Mid-Cretaceous or younger based on the age of the dike cut by the veins (Redman and others, 1984).
Commodities (Major) - Ag, Cu
Development Status: None
Deposit Model: Quartz sulfide veins (Cox and Singer, 1986; model 22c or 36a).
