    Global database boosts critical minerals research: geometallurgy lens for miners

    Global database boosts critical minerals research: geometallurgy lens for miners

    First reported on Australian Mining

    30 Second Briefing

    A new Critical Minerals in Ores – Mineral Chemistry database (CMiO-MIN), developed under the Critical Minerals Mapping Initiative partnership led by Geoscience Australia, compiles global mineral chemistry data to map how critical elements occur within ore minerals. The resource integrates mineral-scale compositional data across multiple deposit types and jurisdictions, giving explorers and survey agencies a consistent framework to compare occurrences and refine targeting models. For geoscientists and miners, it should sharpen geometallurgical predictions, improve resource assessments and support long-term supply planning for critical minerals.

    Technical Brief

    • CMiO-MIN aggregates mineral-scale chemistry from multiple ore deposits into a single harmonised relational database.
    • Standardised mineral and element fields allow cross-comparison of critical element deportment between different deposit types.
    • Database outputs can feed directly into geometallurgical block models and process response predictions at deposit scale.
    • CMiO-MIN supports government resource assessments by linking mineral chemistry to existing national geological survey datasets.
    • Scope is limited to mineral-chemistry data from ores; it does not include full mine production or cost data.
    • As an open, updateable platform, it provides a template for similar critical-mineral datasets across other commodities.

    Our Take

    For projects tagged as Research and Projects in our coverage, operators increasingly use mineral-chemistry databases at the scoping stage to de-risk metallurgy and processing-route selection, suggesting CMiO-MIN could shorten testwork cycles for new critical-mineral developments.

    Because the Critical Minerals Mapping Initiative spans multiple surveys beyond Australia, the CMiO-MIN dataset should help reconcile differing national classifications of ‘critical minerals’, which has been a recurring friction point in cross-border project comparisons in our mining database.

    US DOE $73M Mine of the Future funding: key testbed insights for engineers

    The US Department of Energy has awarded US$73 million through its Mine of the Future initiative to four projects creating national-scale mining testbeds in West Virginia, Colorado, Arizona, Missouri and Texas. Innovative Wireless Technologies will integrate underground and surface sites in Julian, Blacksburg and Idaho Springs to validate next‑generation digital, connectivity and automation systems, while the University of Arizona and University of Missouri will build underground and comminution proving grounds focused on electrification and energy management. Southern Methodist University will repurpose a heavily instrumented Navasota drilling site into a “synthetic mine” for repeatable testing of drilling, sensing and autonomous workflows, aiming to de‑risk commercial deployment.

    Mining leads Canadian PM’s C$1T pitchbook: project finance signals for engineers

    Mining projects dominate Prime Minister Mark Carney’s leaked C$1 trillion, five‑year investment pitchbook, with 63 of 167 opportunities spanning lithium, nickel, graphite, rare earths, gold and copper, and including proposals such as Canada’s first uranium refining and conversion plant in more than 40 years. Confirmed entries range from LithiumBank’s Boardwalk lithium brine project in Alberta, with 5.2 million measured and indicated tonnes LCE at 81.6 mg/L, to Surge Copper’s Berg copper‑molybdenum project, scoped for a 28‑year life and 176 million lb copper per year. Despite a 75% year‑on‑year rise to C$10.1 billion in TSX/TSXV mining equity raisings, pension and sovereign funds remain cautious on finite‑life mines, making long‑life assets and midstream processing plants more likely to secure capital.

    Cyclic Materials’ Mesa rare earth recycling plant: process and scale notes for engineers

    Cyclic Materials has opened a 144,000-square-foot rare earth magnet recycling plant in Mesa, Arizona, designed to process up to 25,000 tonnes per year of magnet-bearing end-of-life products using its proprietary MagCycle mechanical separation technology. The feedstock-agnostic facility is already running at 8 tonnes per hour, producing Mag-Xtract rare earth magnet material and recovering copper, aluminium and steel for sale to US smelters, with over 7,000 tonnes of material already delivered. Backed by more than US$20 million in investment, the plant is intended as a replicable model ahead of a planned South Carolina rare earth recycling campus.
