Comments on the geologic information

  • Geologic Description = A variety of lithologies, including marble, clastic sedimentary rocks, and intrusive and volcanic rocks, have been mapped on the property. Copper-gold-magnetite occurs as skarns developed in the carbonate-rich rocks (K. Adler, Rev. Michael Hornick, personal communication, 1998).
