Electric Power Conversions Australia, Sigma Powertrain and Dayton-Phoenix Group are set to retrofit a Caterpillar 793C mechanical-drive haul truck from Northern Star Resources’ KCGM Operations in Western Australia into a 100% battery-electric unit. The project will replace the diesel engine and mechanical drive with a fully electric drivetrain and high-voltage battery system, effectively creating a zero-exhaust-emission version of a 220–240 t class truck. For mine operators, the retrofit approach offers a potential pathway to decarbonise large fleets without purchasing new OEM battery-electric models.

Catalyst Metals has doubled its revolving credit facility from $100 million to $200 million, taking total available liquidity to $531 million as it advances a multi-mine expansion across Western Australia’s Plutonic Gold Belt. The four-year facility remains fully undrawn, with Catalyst holding $331 million in cash and bullion and carrying no debt, giving substantial headroom for mine development, underground capital and potential plant upgrades. For contractors and suppliers, the strengthened balance sheet signals funding capacity for new drilling campaigns, fleet procurement and possible mill debottlenecking in the belt.

Geopolitical instability, critical minerals supply chain risks and rapid deployment of artificial intelligence will dominate the International Mining and Resources Conference and Expo (IMARC) in Sydney from 29–31 October 2024, which is expected to draw thousands of delegates and hundreds of exhibitors. Global majors, METS companies and governments will use IMARC to negotiate offtake agreements, discuss downstream processing in Australia and test AI tools for orebody modelling, autonomous haulage and plant optimisation. Outcomes will influence capital allocation for Australian copper, lithium and rare earths projects and shape long-term infrastructure and skills planning.
