This site is in the Alaska Peninsula National Wildlife Refuge, near the boundary of land selected by the Bristol Bay Native Corporation.
Location: This site is on the Alaska Peninsula about 0.6 mile north of inner Mitrofania Harbor. It is referred to as SBRGX-46 in Wilson and others (1988, locality 20). The map site is in the SE1/4 of sec. 30, T. 48 S., R. 60 W., of the Seward Meridian. The location is accurate to within 1 mile.
Geology: This occurrence is probably in a mudstone unit of the Upper Cretaceous Hoodoo Formation (Wilson and others, 1995). At this location hornfelsed mudstone crops out near hypabyssal andesite or dacite plugs and dikes (Wilson and others, 1988). Samples collected by the U.S. Geological Survey were reported to be anomalous in antimony, copper, and zinc (Wilson and others, 1988).
Workings: Rock samples 84ACe117 and 84ACe 122, collected by the U.S. Geological Survey in the mid-1980's, were reported to be anomalous in antimony, copper, and zinc (Wilson and others, 1988).
