|Location and accuracy||The approximate location of this occurrence is on the northwest bank of Unuk River about a mile below the Alaska-British Columbia boundary (Elliott and Koch, 1981, p. 8, loc. 13). The location is probably accurate to within about a quarter of a mile.|
Geologic descriptionThe country rocks in the general area of this occurrence are Mesozoic or Paleozoic metasedimentary rocks that locally include marble, and subordinate metavolcanic rocks (Elliott and Koch, 1981; Koch, 1996). The metamorphosed bedded rocks form a mile-wide septum between a stock of Eocene leucocratic quartz monzonite on the north, and a batholith of Tertiary or Cretaceous granodiorite and quartz diorite on the south. The mineral occurrence consists of pyrite, pyrrhotite, and chalcopyrite in a 2-foot thick quartz (?) vein (Wedow and others, 1952, p. 57).
