Brucejack Gold / Silver Mine
Pretivm’s 100%-owned Brucejack is an advanced-stage, high-grade gold exploration project which is part of a largely unexplored land package of over 103,000 hectares located 65 kilometers north of Stewart. Brucejack is comprised of high-grade, visible gold stringers within a lower grade (5 to 20 grams per tonne) gold quartz stockwork system. The Valley of the Kings zone hosts Probable mineral reserves of 6.6 million ounces of gold (15.1 million tonnes grading 13.6 grams per tonne gold).
About This Project
A feasibility study for Brucejack was completed in June for an underground mine with an operating rate of 2,700 tonnes per day using a mining method of long-hole stoping and cemented paste backfill (see news release dated June 11, 2013). Stopes will be mined using a combination of longitudinal and transverse mining, depending on zone width and orientation. Cemented paste tailings will be prepared in a paste plant located on surface near the mill and then pumped underground for distribution to the stopes.
Highlights of the Brucejack feasibility study (using base case US$1,350/oz gold, US$20/oz silver and exchange rate of US$/C$: 1) include:
- Base case pre-tax Net Present Value (5% discount) of US$2.7 billion;
- Mine life of 22 years producing an estimated 7.1 million ounces of gold;
- Average annual production of 425,700 ounces of gold over the first 10 years and 321,500 ounces of gold over the life of mine;
- Base case pre-tax Internal Rate of Return of 42.9%, with payback estimated at 2.1 years;
- Estimated project capital cost, including contingencies, of US$663.5 million;
- Average operating costs of C$156.46/tonne milled over mine life.
Once in operation, Brucejack is expected to employ approximately 500 people. Commercial production at Brucejack is targeted to commence in 2016.
