Four mining technologies from the ARC Training Centre for Integrated Operations for Complex Resources are now ready for field trials, including a digital twin platform for complex orebodies, real-time sensor fusion for ore characterisation, and AI-based decision support for integrated mine-to-mill control. The suite targets data-driven optimisation of drilling, blasting, and processing, with pilots seeking partners across hard-rock operations and brownfield plants. For engineers, the work signals near-term opportunities to plug advanced analytics and automation into existing fleets and control rooms without full greenfield redesigns.

Australian Power Equipment is reframing mine-site optimisation around transformer reliability, availability and lifecycle performance rather than lowest upfront cost, supplying B&D transformers filled with FR3 natural ester fluid instead of mineral oil or diesel-based coolants. The FR3 ester offers higher fire point and biodegradability, enabling compact substation layouts closer to plant and reduced bunding requirements, which can simplify brownfield expansions. For engineers, the shift pushes whole-of-life asset modelling, factoring in longer insulation life, fewer unplanned outages and reduced supply chain risk for critical electrical equipment.

Guardian Metal Resources has expanded its Tempiute tungsten project in Nevada by staking 193 additional claims, increasing its mineral rights footprint by more than 375% to capture what it believes is the full extent of historical tailings from the former Emerson mine. The skarn-type tungsten-zinc-copper-silver operation, located less than 250 miles from Guardian’s Pilot Mountain project, contains tailings from Union Carbide’s 1977–1984 production and has also shown gallium occurrences. CEO Oliver Friesen plans an auger drilling programme to characterise subsurface tailings for near-term tungsten recovery and reclamation, as tungsten prices hit record highs under tightened Chinese export controls.
