Record type Site
Current site name Boxer River

Geographic coordinates

Geographic coordinates: -171.54319, 63.36912 (WGS84)
Relative position This site is located about 3 miles upstream from the mouth of the Boxer River which flows south to its mouth on the southwest coast of St. Lawrence Island. The site is on the east side of the river, at an elevation of about 300 feet, just upstream of the first east tributary. This site was not included by Cobb (1972, 1980).

Alteration

  • (Local) A pyrite gossan in volcanic rocks is present here and alteration is probably significant but it has not been described. The volcanic assemblage is commonly propylitically altered in the region (Patton and Csejtey, 1980).

Comments on the geologic information

  • Geologic Description = A Cretaceous volcanic assemblage of diverse lithologies and compositions makes up the bedrock in the Boxer River drainage (Patton and Csejtey, 1980). A pyrite gossan in volcanic rocks is mapped in the area between the first east tributary and the main drainage of Boxer River (Patton and Csejtey, 1971, p. C9, C12). Stream sediment samples from this east tributary (Patton and Csejtey, 1972) indicate a polymetallic character to nearby mineralization. These stream sediment samples contain up to 150 ppm lead, 2 ppm silver, 50 ppm molybdenum, 700 ppm copper, and 30 ppm tin.
  • Age = Mid-Cretaceous - the age of K/Ar dated intrusive and volcanic rocks on western St. Lawrence Island (Patton and Csejtey, 1980). However, younger Late Cretaceous and Teritary igneous rocks are also present on the island (Patton and Csejtey, 1980) and the age of mineralization could be younger than mid-Cretaceous.
