    Resouro PEA for Tiros rare earth and titanium: project economics for mine planners

    Resouro PEA for Tiros rare earth and titanium: project economics for mine planners

    First reported on MINING.com

    30 Second Briefing

    Resouro Strategic Metals’ PEA for the Tiros rare earths and titanium project in Minas Gerais, Brazil, outlines a 500,000 t/y starter operation producing about 90,000 t/y TiO₂ concentrate and 3,636 t/y TREO over an initial 20-year mine life, with post-tax NPV8 of $714.9 million and IRR of 44.2%. The deposit hosts 1.4 billion tonnes of measured and indicated resources at 12% TiO₂ and 4,000 ppm TREO, with the starter pit targeting less than 1% of this inventory. Near-surface, low-strip mineralisation, conventional processing, and reported recoveries of 68.7% TiO₂ and 67% REE to mixed carbonate underpin the staged development strategy.

    Technical Brief

    • Measured resources total 367 Mt at 12% TiO₂; indicated resources add a further 1 Bt at 12% TiO₂.
    • Combined measured and indicated inventory of 1.4 Bt at 4,000 ppm TREO underpins very long mine-life optionality.
    • Starter pit exploits near-surface, low-strip mineralisation, implying shallow free-dig or short-haul truck–shovel mining.
    • Dual revenue from TiO₂ concentrate and mixed rare earth carbonate reduces single-commodity price risk in cash-flow modelling.
    • Reported TiO₂ overall recovery of 68.7% and 67% REE to MREC assume conventional beneficiation and hydromet flowsheets.

    Our Take

    With a 1.4Bt measured and indicated resource at 12% TiO₂ and only a sub‑1% slice targeted for the 20‑year starter operation, Tiros in Minas Gerais looks more like a multi‑decade district play than a single‑mine plan, which could materially extend life or support staged expansions if infrastructure and permitting in Brazil keep pace.

    The 68.7% TiO₂ and 67% rare earth recovery to mixed rare earth carbonate place Tiros toward the upper end of recovery assumptions seen in our rare earth and titanium project coverage, which, if confirmed at pilot scale, would help the project compete with hard‑rock peers on operating cost despite being in a Latin American rather than Chinese or Australian jurisdiction.

    Carney offers Italy priority access to critical minerals: project and offtake lens for miners

    Canada has granted Italy priority access to its critical mineral reserves, reinforcing a year of bilateral deals including Eni’s nearly C$100 million offtake-linked investment in Nouveau Monde Graphite’s Matawinie graphite project in Québec and Italy’s entry into the Critical Minerals Production Alliance. Rome plans to collaborate with Ottawa on stockpiling, with a clear focus on battery metals and defence-related inputs such as graphite, nickel and rare earths. Parallel talks cover Canada’s planned purchase of Leonardo M‑346 advanced jet trainers and a proposed Defence, Security and Resilience Bank to finance long-term defence projects.

    Scott Technology AMS crush cell: implications for commercial assay workflows

    Scott Technology has secured a major contract to supply an Automated Modular Solution (AMS) crush cell to one of the world’s largest testing, inspection and certification providers, its first deployment of the Rocklabs AMS platform in a large-scale commercial minerals laboratory rather than an on-site mine lab. The modular crush cell automates sample receiving, crushing and splitting, aiming to standardise preparation workflows and reduce manual handling in high-throughput commercial assay operations. For geometallurgy and grade control teams, this signals growing availability of off-the-shelf automation in third‑party lab chains, not just bespoke mine-site systems.

    ABB Grinding Connect for GMDs: reliability and shutdown planning notes for engineers

    ABB has launched Grinding Connect, a global digital service suite for gearless mill drive (GMD) systems that aggregates real-time condition data from critical grinding assets into a secure cloud platform. The service enables remote diagnostics, anomaly detection and predictive maintenance scheduling for large SAG and ball mills, aiming to cut unplanned GMD outages and optimise planned shutdowns. For process and maintenance engineers, the key change is earlier visibility of drive and stator issues, allowing targeted inspections and spares planning rather than time-based overhauls.
