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.

Production Estimates and Economic Highlights(2019 Feasibility Study)(1):

Processing rate 3,800 tonnes per day
Mine life 14 years
Total gold reserves 6.4 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.

2018 Production

Gold production for 2018 was 376,012 ounces of gold at all-in sustaining costs of $764 per ounce of gold sold.

Ramp up to 3,800 Tonnes per Day

In December 2018 we received amended permits by the province of British Columbia to allow us to increase our production through-put rate by 40% from 2,700 tonnes per day to 3,800 tonnes per day. To sustainably process ore at the upgraded production rate, some minor modifications to the mill will be required. These changes should only take a few quarters of incremental work during regularly scheduled shut-downs, and we expect to complete the modifications by the end of the year.

We have also begun accelerating underground development from 700 to 1,000 meters per month. With our mill improvements and accelerated underground development, we expect to be able to feed the mill with 3,800 tonnes per day on a consistent basis by the end of 2019.

2019 Guidance(2)

Gold Production 340,000 – 350,000 ounces
All-in Sustaining Costs $900-$950 per ounce of gold sold
