    TMCR’s $133M Mesabi iron ore royalty: project scale and cashflow notes for mine planners

    First reported on MINING.com

    30 Second Briefing

    TMCR is paying $132.5 million for a 1% index-priced gross overriding royalty on Mesabi Metallics’ Nashwauk taconite project in Minnesota, which is designed for up to 8.5 million tonnes per year of direct-reduction-grade pellets over a 23+ year mine life. The nearly 93%-complete mine and pellet plant, backed by India’s Essar Group and up to $10 billion in US Export-Import Bank support, targets first output in H2 2026 and full production in 2027. TMCR will fund the deal via a $75 million private placement at $13 per share and a proposed $50 million senior secured credit facility.

    Technical Brief

    • TMCR’s 1% gross overriding royalty includes an index-linked revenue floor tied directly to iron ore prices.
    • Essar Group has already invested over $2 billion into mine and pellet plant construction and infrastructure.
    • The US Export-Import Bank has approved up to $10 billion in financial backing for the project.
    • Project completion is reported at about 93%, limiting remaining capex and construction risk before commissioning.
    • TMCR expects up to $13 million per year in royalty cash flow once nameplate production is reached.
    • Acquisition funding comprises a $75 million private placement at $13/share plus a proposed $50 million secured facility.
    • TMCR insiders, including founders, are committing $15 million of the equity raise, increasing alignment with project performance.
    • TMC retains roughly a 25% equity stake in TMCR and options to repurchase portions of associated royalties.
    • TMCR also holds an option to acquire an additional 1% royalty interest on Mesabi after closing.

    Our Take

    TMCR’s move from a 2% royalty on TMC’s NORI polymetallic nodule project into a 1% iron ore royalty at Mesabi shifts part of its portfolio from high‑regulatory‑risk deep‑sea mining into a more conventional US onshore asset, which may help diversify perceived permitting and ESG risk among royalty investors.

    With Mesabi in Minnesota backed for up to $10 billion by the US Export‑Import Bank and already 93% complete, the project sits in a different risk class to many of the critical‑minerals stories in our recent US coverage, where permitting and early‑stage funding rather than construction completion are the main bottlenecks.

    The $75 million private placement at $13 per share, alongside a proposed $50 million credit facility and $15 million from TMCR founders and insiders, effectively leverages a sub‑$1 billion market capitalisation company into a long‑life (>23 years) iron ore royalty, signalling an aggressive balance‑sheet strategy compared with other newly listed royalty vehicles in our database.

    Weir’s WARMAN MCR² mill circuit pump: reliability and wear-control notes for plant engineers

    Weir has introduced the WARMAN MCR² mill circuit pump as an evolution of its existing WARMAN mill circuit range, targeting mineral processing plants facing more complex ores, higher throughput and harsher slurry conditions. The MCR² is engineered to give operators tighter control over wear behaviour, maintenance intervals and overall asset condition in high-duty grinding circuits. For plant engineers, the new design signals further options to stabilise mill discharge pumping performance as ore hardness and variability increase.

    Tivan’s Walshy’s Wall drilling: subsurface targets and RC plan for mine planners

    Tivan has secured final regulatory and heritage approvals to start maiden drilling at the Walshy’s Wall target within the Sandover Fluorite Project in the Northern Territory, with a staged programme of 31 reverse circulation holes scheduled from October. Walshy’s Wall, a manganese–barite gossan discovered by Tivan geologists in October 2025, will be tested for subsurface continuity and grade using RC to penetrate the weathered profile efficiently. Early results will guide follow-up step-out drilling and resource definition across the broader fluorite–manganese system.

    Bellevue Gold board refresh: governance and project finance lens for mine teams

    Bellevue Gold is adding two independent non-executive directors, Debra Counsell and Tanya Rybarczyk, to its board from 23 September 2026 as part of a planned succession process for the Western Australian gold producer. Both bring more than 30 years’ experience spanning mining, resources, finance and infrastructure, signalling a stronger governance and capital markets focus as Bellevue ramps up its namesake underground operation. The appointments point to closer board scrutiny of project financing, risk management and long-term growth options in a volatile gold price environment.
