STEADY-STATE PRODUCTION ACHIEVED AT
THE HIGH-GRADE BRUCEJACK GOLD MINE

Brucejack Mine

The Brucejack Mine is a high-grade gold underground mine located in northwestern British Columbia, approximately 65 kilometers north of Stewart. A year-round, all-weather access road connects the mine to Highway 37. The mine’s operations and camps are fully grid-powered, with diesel backup available. The mine began commercial operation in July 2017 and produced 376,012 ounces of gold in 2018.


Production Estimates and Economic Highlights (2014 Feasibility Study):

Processing rate(1) 2,700 tonnes per day
Mine life(1) 18 years
Total gold reserves(2) 8.7 million oz

The mining method at Brucejack is long-hole stoping using a combination of longitudinal and transverse mining, depending on zone width and orientation. The ore is crushed underground and conveyed to surface where the fully-enclosed mill produces gold-silver dore bars and flotation concentrate.

The tailings are mixed with cement and used as paste backfill in underground voids, with the remainder pumped to the lower depth of Brucejack Lake.

Steady State Production Achieved in 2018

Underground development in 2018 provides access to eight mining levels. With the extension of the mining levels to the east and west within two mining horizons, access to stopes with a range of gold grade is available. Access to the broadest possible range of stopes will maximize stope blending and is expected to improve the management of production grades.

The mine’s grade control program is underway and fully operational. 

2018 Production

Gold production for 2018 was 376,012 ounces of gold.

All-in sustaining costs for the second half of 2018 are expected to range from US$710 per ounce gold sold to US$770 per ounce gold sold. As production has now reached steady state at the Brucejack Mine, an increased focus will be placed on operational efficiency to reduce costs.
