This site is in the Alaska Peninsula National Wildlife Refuge, near land selected by the Aleut corporation.
Location: This site is located on Kupreanof Peninsula approximately 2.55 miles east-southeast of Pad Island and 1.5 miles northeast of Island Bay. It is referred to as SBRGX-42 in Wilson and others (1988, locality 16). The location is accurate to within 2 miles.
Geology: This occurrence is in porphyritic dacite that is part of an undivided sequence of late Miocene volcanic rocks (Wilson and others, 1988, 1995). Potassium-argon dating of hornblende in the dacite gave an age of approximately 10 million years (Wilson and others, 1994). One sample collected by the U.S. Geological Survey was reported to contain anomalous values in silver (Wilson and others, 1988).
Workings: Rock sample 83ACe52 collected by the U. S. Geological Survey in the mid-1980's, was reported to be anomalous in silver (Wilson and others, 1988).
