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

Advancing the Brucejack Mine - Construction Progress

03/09/2017

Construction of the Brucejack Mine has advanced ahead of schedule and dry commissioning of the mill is now planned for March 2017 with wet commissioning expected in early April 2017. Commissioning was previously planned for mid-2017.

Over 144,000 tonnes of ore have been stockpiled on the surface and underground in preparation for mill commissioning. Underground development is well advanced with twelve stopes crosscut on two levels in preparation for long-hole drilling. Cross cutting of another eleven stopes is in progress. A long-hole drill has been mobilized, with long-hole drilling of a test stope underway.

All major mechanical and electrical components have been delivered to site and installation and assembly is ongoing. The shell, heads, gears motors and drives for the SAG and Ball mills have been installed and the drives are scheduled to be energized in late March. Electrical and instrumentation along with mechanical and piping installation within the mill building is ongoing. The mine substation and central electrical room are ready for energization.

The 330-person camp which includes mine dry, offices, recreation facilities, dining hall and kitchen has been commissioned and is fully operational.

Construction continues on the Valley of the Kings portal building. External structural steel erection is complete and internal structural steel, mechanical and electrical installation is progressing. The portal will serve as the primary access point to convey the gold ore from the underground crusher to the mill.

Construction of the 57-kilometer long transmission line is nearing completion. All of the towers are in place and the first 42kilometer section is energized to the Knipple substation. The final 15-kilometer section of the transmission line is 97% complete and expected to be energized in late Q1 2017. An additional six 2-megawatt diesel generators are fully commissioned and, combined with our initial 5-megawatts of diesel power, can provide adequate power to maintain full mill and underground production in the event of any grid power interruption.

Underground development remains on schedule and contract mining crews have completed over 10,000 meters of underground development to date. Access to eight production levels from the 1200 to 1410-meter levels has been established. Long-hole drilling has been in progress on a test stope on the 1320-meter level since mid-February. Excavation of the major development infrastructure is now complete. The third and final exhaust vent raise has broken through to the surface. Underground work is focused on continued ramp and level development. Construction of underground infrastructure, including the crusher, conveyor, and transfer towers continues.
