    BHP steel decarbonisation trials: retrofit pathways and risks for mine planners

    BHP steel decarbonisation trials: retrofit pathways and risks for mine planners

    First reported on Australian Mining

    30 Second Briefing

    BHP is pushing ahead with lower-emission steelmaking, reporting progress across industrial trials and technology partnerships with 13 major steelmakers that together produce about a quarter of global steel. The programme spans blast furnace and direct reduced iron routes, including pilots using higher-grade iron ore, biomass and hydrogen-based reductants to cut coke rates and CO₂ intensity per tonne of hot metal. Management notes that high capital costs and weaker steel margins are slowing sector-wide investment, making scalable retrofits to existing furnaces a key near-term focus for miners and mills.

    Technical Brief

    • For other miners and mills, retrofit-friendly measures offer near-term abatement without full asset replacement.

    Our Take

    BHP’s work with 13 steelmakers on decarbonisation sits alongside its recent battery-electric haul truck trials at the Jimblebar iron ore mine, signalling that the company is attacking Scope 1 and Scope 3 emissions in parallel across both mining and downstream steel use.

    2027 PDAC Awards: key project and sustainability lessons for mining teams

    PDAC has named six recipients of the 2027 PDAC Awards, recognising achievements spanning early-stage discovery, major mine development and sustainability in Canadian and international projects. The awards cover categories such as mineral exploration, mine builders, sustainability and indigenous engagement, with winners typically selected for discoveries that add multi-million-ounce gold or multi-million-tonne base metal resources and for projects that reach commercial production on time and budget. For engineers and geoscientists, the list signals which exploration models, development strategies and community partnership approaches are currently being held up as best practice.

    Putzmeister Underground–Cannon Mining Mexico deal: fleet support gains for mine engineers

    Putzmeister Underground Division has appointed Cannon Mining Latin America as its exclusive distributor for Mexico, covering shotcrete equipment, concrete transporters and other specialist underground mining solutions. The deal aims to expand parts and service coverage across key mining regions such as Sonora and Zacatecas through Cannon’s local workshops and field service teams. For mine operators, the partnership should shorten lead times for fleet support and commissioning of new underground concrete placement systems, reducing reliance on imports and remote technical support.

    Epiroc Autonomous SmartROC D65 MKII drills: deployment lessons for mine engineers

    Epiroc’s fleet of Autonomous SmartROC D65 MKII blasthole drills is expanding across mining and quarrying, with units now running at Fortescue’s Solomon and Eliwana iron ore operations in Australia and at Luck Stone’s Rockville quarry in the United States. The rigs automate drilling cycles for production blastholes, delivering repeatable hole depth and spacing and reducing operator exposure at the bench. For engineers, the deployment signals growing acceptance of OEM autonomy for large-scale production drilling rather than limited trial use.
