Comments on the geologic information

  • Geologic Description = Greenstone, slate, and graywacke of the Tertiary Orca Group are cut by mineralized shear zones. Zones range from 4 inches to 20 ft wide and contain sphalerite, galena, pyrite, and arsenopyrite (Jansons and others, 1984).? Jansons and others (1984) reported six chip samples contained from 39 ppm to 1.75 percent Zn, less than 1 ppm to 0.14 percent Pb, 0.3 to 8.2 ppm Ag, and less than 10 ppm to 1.6 percent As. Grab samples contained from 36 ppm to 3.2 percent Zn, 5 ppm to 2.6 percent Pb, and less than 0.1 ppm to 8 oz/ton Ag.
  • Age = Paleocene or younger; mineralized shear zones cut greenstone, slate, and graywacke of the Tertiary Orca Group.

Mining district

District name Prince William Sound

Comments on the production information

  • Production Notes = No production.

Comments on the workings information

  • Workings / Exploration = Jansons and others (1984) reported six chip samples contain from 39 ppm to 1.75 percent Zn, less than 1 ppm to 0.14 percent Pb, 0.3 to 8.2 ppm Ag, and less than 10 ppm to 1.6 percent As. Grab samples contain from 36 ppm to 3.2 percent Zn, 5 ppm to 2.6 percent Pb, and less than 0.1 ppm to 8 oz/ton Ag. The potential for mineral development is moderate, although no development has occurred to date (Jansons and others, 1984).
