Comments on the geologic information

  • Geologic Description = This occurrence consists of talus blocks of slate and greenstone at the base of iron-stained outcrop. The slate contains chalcopyrite, pyrite, and sphalerite. The greenstone contains chalcopyrite and pyrrhotite (Jansons and others, 1984). Host rocks mapped as part of the Tertiary Orca Group (Nelson and others, 1985). Three grab samples contained from 210 ppm to 0.77% Zn.
