Geologic information

Identification information

Deposit ID 10308348
Record type Site
Current site name Unnamed (near Shelter Cove)

Geographic coordinates

Geographic coordinates: -150.62553, 59.52248 (WGS84)
Relative position Two occurrences are located on the southeast shore of West Arm of Nuka Bay, near the mouth of Beauty Bay. Both occurrences are exposed on the sea cliff. The northern most exposure is a two-foot-wide vein which strikes N80E. The southern occurrence is about 0.3 miles south of the northern exposure and consists of a four-foot-wide zone of quartz and fractured graywacke. This is Cobb's (1972, MF-397) location 18 and Richter's (1970) locations 11 and 12. This location is accurate to within a quarter of a mile.

Comments on the geologic information

  • Geologic Description = Both occurrences are in massive graywacke of the Cretaceous Valdez Group (Richter, 1970). The northern most exposure is a two-foot-wide quartz-arsenopyrite vein that strikes N80E. and dips vertically. The vein has a thin clay gouge zone in the center and along the hanging wall margin. A single channel sample assayed 0.02 ppm gold (Richter, 1970). The southern occurrence is a four-foot-wide zone of fractured graywacke with quartz-arsenopyrite lens that varies from 0.5- to 2-feet-thick. A two foot channel sample taken across the widest part of the mineralization contained 0.062 ppm gold (Richter, 1970).
  • Age = Tertiary; Boden and others (1991) report other veins in the district are about 55 m.y. old.
