The Kemess South deposit is a large, gold-copper porphyry containing proven reserves of 
67 million tonnes. The Kemess South deposit is flat-lying and has uniform gold and copper grades throughout. These characteristics make the ore reserve relatively insensitive to changes in metal prices.

The deposit contains three principal types of ore:
  • a primary-sulphide hypogene ore;
  • a copper-enriched secondary sulphide ore; and,
  • an oxidized leach cap ore.

Currently, the hypogene ore makes up approximately 85% of the ore body.
