| Abstract | During the winter of 1972-73, thirty-three holes averaging 100 feet in length were drilled on the geophysical test range in Cavendish Township, Ontario. The bedrock consists of Grenville mafic gneiss,
crystalline limestone and granitic gneiss. Two zones of pyrite-pyrrhotite concentration are found within the gneisses. Each zone is characterized by an outer region containing approximately 2% sulphides, and an inner region with concentrations of up
to 10% sulphides. The two zones appear to dip towards each other. Although traces of sphalerite and chalcopyrite were observed, no base metal concentration in excess of 600 parts per million was found. |
