Feasibility Study Highlights
- Increase in Valley of the Kings Mineral Reserve gold grade:
- Valley of the Kings Proven and Probable Mineral Reserves of 6.9 million ounces of gold (13.6 million tonnes grading 15.7 grams of gold per tonne)
- West Zone Proven and Probable Mineral Reserves of 0.6 million ounces of gold (2.9 million tonnes grading 6.9 grams of gold per tonne);
- Gold and silver recoveries of 96.7% and 90.0% over mine life;
- Mine life of 18 years producing an estimated 7.27 million ounces of gold;
- Average annual production of 504,000 ounces of gold over the first 8 years and 404,000 ounces of gold over mine life;
- Estimated project capital cost, including contingencies, of
US$746.9 million ; - Average operating costs of
C$163.05 /tonne milled over mine life; - Base case economics: At
US$1,100 /ounce gold,US$17 /ounce silver and exchange rate of0.92 US$ /C$, Brucejack has a pre-tax net present value ("NPV") at a 5% discount ofUS$2.25 billion (US$1.45 billion post-tax), a pre-tax internal rate of return ("IRR") of 34.7%, and a pre-tax payback period of 2.7 years; - Alternative high case economics: At
US$1,400 /ounce gold,US$21 /ounce silver and exchange rate of0.92 US$ /C$, Brucejack has a pre-tax NPV at a 5% discount ofUS$3.54 billion (US$2.28 billion post-tax), a pre-tax IRR of 47%, and a pre-tax payback period of 2 years.

Project Mineral Reserves
The Mineral Reserves resulting from the Feasibility Study for the Brucejack Project are based on the December 2013 Mineral Resource estimates for the Valley of the Kings and the West Zone (see news release dated December 19, 2013 ). The Mineral Reserve estimates by zone and Reserve category are summarized below.
