Comments on the geologic information

  • Geologic Description = Jansons and others (1984) reported four shear zones that range in size from 3 inches to 18 ft wide cutting massive, clast-supported pebble, cobble, and boulder conglomerate and matrix-supported pebbly mudstone and sandstone of the Tertiary Orca Group. Shear zones are traceable for 800 ft along strike. Zones contain sulfide occurrences ranging from 1 inch wide veinlets of chalcopyrite and pyrite to 4 ft wide zones of chalcopyrite. Sulfide deposits are traceable for about 200 ft.? Six chip samples contained 700 ppm to 7 percent copper, 0.33 oz/ton to 8 oz/ton Ag, 0.16 to 0.87 percent Zn, and 240 ppm to 720 ppm Pb. Grab sample contained 0.12 percent Cu, 15.4 ppm Ag, 0.18 percent Zn and 815 ppm Pb (Jansons and others, 1984).
  • Age = Paleocene or younger; mineralized shear zones are in sedimentary rocks of the Early Tertiary Orca Group.

Economic information about the deposit and operations

Development status Prospect
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Prince William Sound

Comments on the production information

  • Production Notes = No production.

Comments on the reserve resource information

  • Reserves = Inferred reserves 11,000 tons at 1.57 percent Cu and 50 ppm Ag (Jansons and others, 1984).

Comments on the workings information

  • Workings / Exploration = Open pits, but no production reported. Six chip samples contained 700 ppm to 7 percent copper, 0.33 oz/ton to 8 oz /ton Ag, 0.16 to 0.87 percent Zn, and 240 ppm to 720 ppm Pb. Grab sample contained 0.12 percent Cu, 15.4 ppm Ag, 0.18 percent Zn and 815 ppm Pb. Low mineral development potential (Jansons and others, 1984).
