Brucejack Gold Mine is a high-grade underground mining operation using the long-hole stoping mining method (both transverse and longitudinal) and cemented paste backfill.
In 2020, the ramp-up period to a maximum output of 3,800 t/d is complete, with production averaging 1.3 Mt annually.
The updated underground mine design supports the extraction of 3,800 t/d of ore through a combination of transverse and longitudinal LHOS. Paste backfill is integral to the mine plan to maximize both orebody recovery and mining productivity. Modern trackless mobile equipment is employed in the majority of mining activities.
A main decline, designated as the Valley of the Kings access, extends from the surface portal near the concentrator and is used to access the mine and as a conveyor way. The conveyors installed have a combined length of 800 m. The existing West Zone portal will continue to provide access (and egress) to the mine and serve as the main access for large underground equipment and waste haulage.
A fleet of LHD and underground trucks are used for material loading and transport from the underground working areas and through an internal ramp system that connects all levels to the centrally located crusher.
Major underground infrastructure includes crusher, conveyors, ventilation raises, fans, heating system, pumping stations, electrical substations, explosives magazines, paste fill booster pump station, refuges, mine communica ........
