Komatsu and partners are advancing automated megawatt-class charging for battery-electric haul trucks, focusing on DC arc flash management, battery chemistry trade-offs and robust battery management systems discussed at The Electric Mine 2026 in Lisbon. Technical sessions examined safe operation of high-voltage DC connectors at MW power levels, thermal behaviour of different chemistries under rapid charge, and integration of BMS with mine energy management. For mine designers, the work signals tighter coupling between charger layout, electrical protection schemes and vehicle interface standards in future BEV fleets.

Spence and Sierra Gorda SCM copper mines have signed a Memorandum of Understanding at Exponor 2026 in Antofagasta to identify and evaluate joint technical and commercial initiatives to boost operational efficiency and competitiveness. The MoU links BHP’s Spence operation with Sierra Gorda SCM, owned 55% by KGHM and 45% by South32, creating a formal framework for shared work on items such as processing performance, cost structures and supply contracts. For engineers, the move signals potential alignment on plant benchmarking, technology trials and common service providers across neighbouring large-scale sulphide operations in northern Chile.

Zenith Minerals has agreed a binding takeover implementation deed with Forrestania Resources for an all-scrip, off‑market acquisition valuing Zenith at about $93.5 million. Zenith shareholders will receive one new Forrestania share for every 4.3 Zenith shares, implying $0.132 per Zenith share based on the agreed exchange ratio. The deal consolidates Forrestania’s and Zenith’s gold and battery metals exploration portfolios under a single ASX vehicle, which may affect future drilling priorities, capital allocation and JV negotiations across their Western Australian tenements.
