The site is located on land selected by the Aleut Corporation.
Location: This site is located on the Alaska Peninsula on the west side of Clark Bay approximately 2 miles north of Waterfall Point. It is referred to as PMRGX-16 by Wilson and others (1988, locality 65). The locality is accurate to within 1,000 feet.
Geology: Wilson and others (1988) describe this occurrence as a vertical, sericitically altered, zone containing abundant sulfides in volcaniclastic sandstone and siltstone (Wilson and others, 1988). The sedimentary rocks probably are part of the Paleocene to Eocene Tolstoi Formation (Wilson and others, 1995). Amygdaloidal andesite flows are also present in the area. One sample collected by the U.S. Geological Survey in the mid-1980's was reported to be anomalous in antimony, arsenic, barium, and zinc (Wilson and others, 1988).
Workings: Rock sample 83AWs91, collected by the U.S. Geological Survey in the mid-1980s, is reported to be anomalous in antimony, arsenic, barium, and zinc (Wilson and others, 1988).
Age: Tertiary.
Alteration: Sericite alteration is present in an altered zone within sandstone and siltstone.
