Immersive thermal management for heavy-duty electric mining machinery is emerging as a key constraint and enabler as non-road mobile machinery is projected to rise from 16% to 37% of global NOx emissions by 2050. Developers are moving beyond simple liquid cooling to tightly integrated systems that co-optimise battery packs, inverters and high-power traction motors under high-load, low-speed duty cycles typical of underground haul trucks and loaders. For engineers, the message is that thermal design now directly governs achievable power density, duty cycle length and battery life in next-generation electric fleets.

Komatsu has opened a new full-service parts distribution centre in St. Albert, near Edmonton, to support its Canadian mining fleet with faster access to critical components. The facility is designed to expand parts availability and shorten distribution lead times for dealers, improving turnaround on major items such as truck and shovel components and planned maintenance kits. For mine operators running large Komatsu haul trucks and loading equipment in remote Alberta and northern sites, the move should reduce downtime risk linked to long-distance parts logistics.

Maritana Minerals has lifted the Burbanks gold project mineral resource to 13.7 million tonnes at 1.7g/t for 755,000oz, adding 290,000oz and taking its total company mineral resource inventory above 2Moz. The Western Australian project’s previous estimate was 6.1Mt at 2.4g/t, so tonnage has more than doubled while grade has fallen, implying a larger, lower‑grade envelope. For mine planning and geotechnical teams, this shift points to potentially expanded pit shells or underground footprints, altered stripping ratios, and revised economic cut-off assumptions.
