Location: This occurrence is at an elevation of about 2,750 feet about 0.7 miles north of the summit of Mount Kashagnak. It is at the east-central edge of section 6, T. 29 S., R. 58 E. of the Copper River Meridian. It is shown as mineral occurrence 13 by Redman and others (1984) and as number S043 by Wells and others (1986).
Geology: According to Redman and others (1984), a few rare, thin quartz veins 0.04 to 0.16 inches wide can be traced for at least 10 feet. The veins contain small amounts of molybdenum, gold, and silver. One sample of a single vein with attached wallrock contained 137 ppm molybdenum, 2.3 ppm silver, and 0.7 ppm gold. The veins occur within the biotite-quartz-monzonite-porphyry core of the mid-Cretaceous Mount Kashagnak pluton.
Age: Mid-Cretaceous or younger based on the age of the Mount Kashagnak pluton (Redman and others, 1984).
Commodities (Major) - Ag, Au, Mo
