Brucejack Mine Construction Advancing Ahead of Schedule

02/03/2017

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

Over 110,000 tonnes of ore has been stockpiled on surface and underground in preparation for mill commissioning. Underground development is well advanced with eleven stopes crosscut on two levels in preparation for long-hole drilling and cross cutting of a further four stopes in progress.  Long-hole drills are being mobilized, with long-hole drilling expected to commence the second week of March.

All major components have been delivered to site and installation and assembly is ongoing. Process tank installation is 75% complete. The shell and heads for the SAG and Ball mills have been installed.  Electrical and instrumentation along with other mechanical and piping installation within the mill building is ongoing.

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 substantially complete.  The portal will serve as the primary access point to convey the gold ore from the underground crusher to the mill.

The transmission line construction is nearing completion. As previously reported, all of the towers are in place and the first 42 kilometers of the 57-kilometer transmission line is energized to the Knipple substation.  The final 15-kilometer section of the transmission line is 90% complete and expected to be energized this quarter.  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. Excavation of the major development infrastructure is now complete. The third and final exhaust vent raise has broken through to surface.  Underground work is focused on continued ramp and level development.  Construction of underground infrastructure, including the crusher, conveyor, and transfer tower continues.
