    Meridian London listing: Cabaçal capex, NPV and schedule explained for mine planners

    First reported on MINING.com

    30 Second Briefing

    Gold-copper explorer Meridian Mining plans to list on the London Stock Exchange’s main market on 1 May under ticker MNO, raising about £25 million at 92 pence per share in a dual listing fully fungible with its TSX stock. Proceeds, combined with existing cash of £55.1 million, will fund long-lead equipment, infrastructure and civil works at the Cabaçal open-pit project in Mato Grosso, which has a 2025 PFS showing a US$984 million NPV (5%), 61% post-tax IRR and 141,000 oz/y gold-equivalent output over 10 years. Permitting is advanced with a preliminary licence granted, and a definitive feasibility study is targeted for Q4 ahead of a construction decision.

    Technical Brief

    • Initial capex for Cabaçal is estimated at US$248 million, with a projected 17‑month payback.
    • Prefeasibility work assumes a shallow open‑pit exploiting favourable strip ratios for rapid, low‑complexity mining.
    • All‑in sustaining costs are projected at US$742/oz AuEq over the 10‑year mine life.
    • Cabaçal lies ~1,700 km north‑west of Rio de Janeiro, implying long overland logistics for equipment and consumables.
    • A key preliminary environmental licence was secured in 2025, de‑risking the subsequent construction permitting pathway.
    • Regional exploration covers a 50‑km VMS belt, with Santa Helena prioritised as the next development‑stage satellite deposit.
    • Hub‑and‑spoke development across adjacent greenstone belts could leverage shared processing and infrastructure, lowering unit capital intensity.

    Our Take

    With a post-tax IRR of 61% and a 17‑month payback on the Cabaçal gold‑copper project, Meridian Mining screens as one of the higher‑margin Latin American copper‑gold entries in our Mining database, which is likely to attract UK institutions looking for growth exposure rather than replacement‑grade assets.

    The planned London Stock Exchange listing, at a modest discount to the TSX price, positions Meridian alongside a relatively small cohort of Brazil‑focused copper and gold names in Europe, giving UK investors direct leverage to Mato Grosso geology rather than the more common Andean copper stories in our coverage.

    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.
