Borden Gold Case Study
All-electric mines are not new . Newmont made its Borden Gold project in Canada all-electric back in 2019 , replacing all of its underground diesel fleet of trucks with BEVs . Newmont says this not only makes the mine more efficient but also improves health & safety and reduces the environmental footprint .
Newmont worked with Sandvik Mining and MacLean Engineering on the BEVs . The tech included drilling and blasting equipment , electric bolters , personnel carriers and a 40-tonne haul truck .
The company says it has reduced GHG emissions by 50 %, or 5,000 tonnes of CO2 per year , and reduced underground ventilation requirements by half .
