Comments on the geologic information

  • Geologic Description = The country rocks at these prospects are mafic volcanic rocks and sedimentary rocks of the Tertiary Orca Group (Nelson and others, 1985). The deposit consists of irregular masses of chalcopyrite, pyrite, pyrrhotite, and sphalerite in a shear zone up to four feet wide in mafic volcanic rocks (Jansons and others, 1984).? the prospect was explored by a 13-foot shaft and several surface excavations. Six chip samples contained 620 ppm to 0.37% Cu (Jansons and others, 1984).
  • Age = Probably Tertiary based on the age of the host rocks.

General comments

Subject category Comment text
Deposit Model Name = Cyprus massive sulfide (Cox and Singer, 1986; model 24a)
Deposit Other Comments = Nelson and others (1985) interpret the country rocks as accreted ocean crust. Crowe and others (1992; 1993) and Sainsbury (1993) discuss the genesis of the volcanogenic massive sulfide deposits in this area.? Chugach Alaska Corporation, Anchorage, Alaska has control of these lands.
