With its connection to the provincial hydro-electric power grid, Pretivm’s Brucejack Mine is already a low-carbon gold producer. But we know there are opportunities to further reduce carbon emissions. Diesel powered underground haul trucks are the largest source of greenhouse gas emissions at the mine and we have been assessing the potential to transition this equipment to zero emission units since 2019.
In 2020 we began operating one battery electric Sandvik Z50 truck on a trial basis. The truck has a 50- tonne capacity and produces zero emissions. Due to the success of the trial program, we have committed to a full replacement of the existing diesel haul truck fleet with seven of the 50-tonne Z50 vehicles by the end of 2023. Once fully operational, the Z50 fleet will reduce GHG emissions from the mine by nearly 7,000 tonnes annually. In addition to reduced GHG emissions, the zero-emission fleet will reduce operational costs, improve working conditions in the underground mine, and provide valuable training opportunities with new technology for our workforce. Brucejack is one of only two mines in Canada that have introduced this technology; we hope that our investment supports an acceleration in the transition towards lower emission mining in Canada and beyond.
Pretivm’s $16.3M investment in this initiative is supported by the CleanBC Industry Fund and includes $7.95M from the provincial program. CleanBC reinvests a percentage of the carbon tax to accelerate industry performance on emissions reductions.
