|Location and accuracy||This occurrence is on a ridge crest east of Monahan Creek. It is near elevation 6102 in the center of the S1/2 of section 22, T. 9 S., R. 12 E. of the Copper River Meridian. This is locality 22 of MacKevett (1976). The location is probably accurate to within 1,000 feet.|
Geologic descriptionThis occurrence consists of numerous thin, sulfide-bearing quartz veins that cut Cretaceous Valdez Group metaflysch (MacKevett, 1976). The veins are assumed to be gold-bearing, like many other similar deposits in the general area (for example: MC189 through MC194). Gold-bearing quartz veins in the Valdez Group are generally Early Tertiary in age (Goldfarb and others, 1997).
