Location and accuracy This prospect is on the southwest flank of peak 6635. It is at an elevation of about 5,800 feet, 6,500 feet east of the mouth of Standard Creek near the northwest corner of section 14, T. 10 S., R. 11 E. of the Copper River Meridian. This is locality 7 of MacKevett (1976); the location is probably accurate to within 1,000 feet.

Geologic setting

Geologic description

Minor surface workings were noted at this prospect (MacKevett, 1976). The deposit that was prospected is inferred to be gold-bearing quartz vein(s) in the Cretaceous Valdez Group metaflysch similar to other lode gold deposits in the area, such as MC190 and MC193 (MacKevett, 1976, 1978). Gold-bearing quartz veins in the Valdez Group are generally Early Tertiary in age (Goldfarb and others, 1997).
