Kirkland Lake Gold says it is expecting to receive a 50 t battery-powered Z50 underground haul truck at its Macassa gold mine, in Ontario, Canada, this quarter, following a purchase agreement signed last year.
The gold miner’s Macassa operation has been a leading adopter of new electric equipment and already has four 40 t battery-powered machines at the underground mine. These are matched by many battery-powered LHDs made by likes of Artisan Vehicle Systems and Epiroc.
The latest 50 t vehicle will come from Artisan, a Sandvik Mining and Rock Solutions business unit.
The Z50 haul truck is a ground-up design that seamlessly integrates the most capable and proven battery-electric powertrain available in the mining industry with the latest and most coveted features of any haul truck on the market today, according to Sandvik. The 50 t machine is based off the existing design for the Z40 truck, which Artisan released back in 2018, but features a stretched rear frame (close to 19 in).
It is equipped with AutoSwap, a patented self-swapping system for the Artisan battery pack. This makes battery swapping faster and easier with a minimum amount of manual handling: changing the battery only takes about six minutes, and it can be done in a passing bay or old re-muck bay with no overhead cranes or external infrastructure needed, Sandvik says.
The news of the pending arrival of this electric vehicle came at the same time as Kirkland Lake released its 2020 production results. The company produced 369,434 oz of gold in the December quarter to make a total of 1.37 Moz of gold in 2020, 41% higher than the total in 2019, which was in line with its full-year 2020 guidance of 1.35-1.4 Moz.
