|Location and accuracy||This occurrence is located on the coast of Unga Island between Baralof Bay and Delarof Harbor. It is referred to as PMRGX-2 in Wilson and others (1988, locality 52). The map site is 1.5 miles west-northwest of Kelly Rock. The location is accurate to within 1,200 feet.|
Geologic descriptionThis occurrence consists of a pyrite-rich dolomitic vein that cuts sheared volcaniclastic rocks of the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995). Samples of the vein and of nearby rhyolite were reported to be marginally anomalous in copper, lead, arsenic, and antimony (Wilson and others, 1988).
