This site is located on land interim-conveyed to, or patented by, the Bristol Bay Native Corporation.
Location: This site is on the west coast of Coal Cape, about 1.2 miles south of the top of Red Bluff Mountain. It is referred to as SBRGX-48 in Wilson and others (1988, locality 22). The location is accurate to within 1,200 feet.
Geology: At this occurrence the rocks consist primarily of sandstone and shale of the Paleocene to Eocene Tolstoi Formation. The site is near the contact with the Eocene to Oligocene Meshik Formation (Wilson and others, 1995). The sedimentary rocks are cut by andesite or basalt dikes that tend to be pyritized and iron-stained. The sandstone locally contains disseminated pyrite and rare aggregates of pyrite. Some small, barren, calcite veins occur in fracture zones. Samples collected by the U.S. Geological Survey were reported to contain anomalous amounts of lead, zinc, antimony, and arsenic (Wilson and others, 1988).
Workings: Rock samples 84AGe21-26, collected by the U.S. Geological Survey in the mid-1980's, were reported to contain anomalous amounts of lead, zinc, antimony, and arsenic (Wilson and others, 1988).
Age: Tertiary.
Alteration: Pyritization and iron-staining.
