Resource Industry Network is campaigning across Bowen, Surat and Galilee coal regions as Queensland’s revised regulatory frameworks and higher coal royalties threaten margins for miners and the METS supply chain. General manager Dean Kirkwood warns that hundreds of small and mid-sized contractors in Mackay and other hubs – from heavy fabrication workshops to drill and blast service providers – face reduced forward work and curtailed investment in new fleets. For geotechnical and mining engineers, the shift signals tighter project pipelines, delayed brownfield expansions and greater scrutiny on cost and schedule risk in coal-related work.

Battery-electric support fleets, including graders, water carts and service trucks, are emerging as a near-term decarbonisation lever for Australian mines, avoiding the payload and duty-cycle constraints that still limit 220–400 t battery-electric haul trucks. OEMs such as XCMG are field-testing high-voltage, fast-charge support equipment in demanding pit environments, targeting shift-length operation with opportunistic charging during breaks. For mine planners and maintenance teams, this shifts immediate focus to site-wide power distribution, charging bay layout and thermal management of batteries rather than wholesale replacement of primary production fleets.

Terrain Minerals has reported a maiden Inferred Mineral Resource Estimate of 677,000 tonnes at 2.5g/t gold for 54,000oz at the Lightning deposit, part of its 100 per cent-owned Smokebush gold–silver project in Western Australia’s Murchison region. The resource provides an initial inventory for potential open-pit and underground evaluation, with grade and tonnage in the typical range for small to mid-scale Murchison shear-hosted gold systems. For geotechnical and mine planning teams, the defined tonnage and grade support early-stage pit shell optimisation, geometallurgical testwork scheduling, and targeted infill drilling design.
