    Meridian’s Cabaçal NPV doubles: project economics and capex lens for mine planners

    Meridian’s Cabaçal NPV doubles: project economics and capex lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    Meridian Mining’s updated feasibility study for the Cabaçal gold-copper project in Mato Grosso more than doubles after-tax NPV to US$2.09 billion, assuming US$3,570/oz gold, US$5.03/lb copper and US$50.17/oz silver, with an IRR of 108% and an 11‑month payback on US$322 million initial capex. The staged open-pit plan is based on 56.04 million tonnes of proven and probable reserves grading 0.61 g/t gold and 0.35% copper, ramping plant throughput from 1.93 Mt/y to 4.5 Mt/y via a US$56 million expansion. Meridian forecasts first‑five‑year output averaging 183,500 gold‑equivalent oz/y at US$715/oz AISC, with installation licence approval and project financing still pending.

    Technical Brief

    • Mine life totals 13.9 years: ~10 years open-pit mining plus 3.9 years stockpile processing.
    • Proven and probable reserves increased 34% versus 2025 PFS, from 41.7 Mt to 56.04 Mt.
    • Reserve inventory contains 1.11 Moz Au, 430 Mlb Cu and 2.39 Moz Ag in situ.
    • Recovered metal over life-of-mine is estimated at 983,500 oz Au, 180,600 t Cu and 1.78 Moz Ag.
    • Year‑one plant feed is heavily front‑loaded: 2.8 g/t Au, 0.71% Cu, 2.69 g/t Ag.
    • Throughput steps from 1.93 Mt/y (year 1) to 2.5 Mt/y (years 2–3) then 4.5 Mt/y from year 4.
    • Expansion to 4.5 Mt/y requires an additional US$56 million, with sustaining capital US$74 million and closure US$59 million.
    • Operating cost is forecast at US$22.41/t milled after Brazilian tax credits, with 10% capex contingency.
    • Mine plan must remain within the preliminary licence footprint; any larger pit or higher tonnage needs permit amendment.
    • Meridian has committed US$15.9 million to pre‑construction, ordered SAG and regrind mills, and opened a data room for ~30 lenders.

    Our Take

    With Meridian Mining now valued at about US$1.07 billion and having raised roughly US$34 million in its London debut on 1 May 2026, the Cabaçal gold-copper project in Brazil is effectively anchoring a mid-cap developer profile rather than a junior, which can broaden the pool of institutional lenders beyond the 30 already in the data room.

    Nth Cycle–Glencore $1bn offtake: project SHIELD implications for mine planners

    Nth Cycle has signed a binding 10-year offtake term sheet with Glencore worth an estimated $1 billion, securing 100% of black mass feedstock from Glencore’s US shredding network for Project SHIELD, its planned South Carolina battery materials refinery. The deal covers offtake of high-purity mixed hydroxide precipitate (nickel/cobalt MHP) and battery-grade lithium carbonate, and includes assessing an existing Glencore US site to accelerate construction alongside Nth Cycle’s 21,000-square-foot Fairfield, Ohio facility. Both parties will also evaluate deploying Nth Cycle’s portable ‘Oyster’ electrochemical refining system for black mass, copper and rare earth recovery in Europe and globally.

    Military Metals’ West Gore antimony-gold grant: drilling focus and notes for mine planners

    Military Metals has secured a C$100,000 Mineral Resource Development Fund grant from the Nova Scotia Department of Natural Resources to support a seven-hole, 1,750 m diamond drilling programme at the past-producing West Gore antimony-gold project in the Meguma camp. Drilling will test down-plunge extensions below historical mine workings and the Brook Vein stope, following historical intercepts up to 10.6 g/t gold and 3.4% antimony over 7.1 m. West Gore previously produced an estimated 7,761 t of 46% Sb concentrate and 7,149 oz gold but has seen only minor work since the 1960s.

    Mining ‘mini armies’ in Burkina Faso and Mali: security lessons for mine planners

    Mining companies in Burkina Faso and Mali have built “mini armies” and effectively turned mine sites into “mini states” as central governments and local militaries lose control of territory, says George McLeod of Critical Risk Team. Operations are being maintained by focusing narrowly on secure logistics corridors for inbound supplies and outbound concentrate, allowing projects to function in what he calls a “complete and total power vacuum”. McLeod also expects China’s dominance in rare earths refining to erode within about three years as Australia, the US and Brazil commission new processing capacity and substitution technologies reduce demand.
