Relative position The Charles Frank mine is located 1.8 miles north of Moss Point on the west shore of the Nuka Bay's North Arm. A caved adit exists just above the high tide line and about 40 feet below the discovery outcrops. This is Cobb's (1972, MF-397) location 22 and Richter's (1970) location 2. This location is accurate to within 300 feet.

Comments on the geologic information

  • Geologic Description = The prospect consists of two quartz-arsenopyrite veins that cut Cretaceous Valdez Group black slate (Richter, 1970). Pilgrim (1933), describes the vein as being 8 to 14 inches wide, it trends N53E and dips 79N. Near the caved portal the black slate strikes N25E and dips 35W. A 60 foot adit was driven N50W where it intersected the vein. A total of 51 feet of drift was driven along the vein eight feet to the southwest and 43 feet to the northeast (Pilgrim, 1933). Grab samples from the dump contained 0.04 ppm gold (Richter, 1970).
  • Age = Tertiary; Boden and others (1991) report other veins in the district are about 55 m.y. old.
