    NGEx Valle Ancho spin-out: exploration, valuation and NAV lens for mine planners

    NGEx Valle Ancho spin-out: exploration, valuation and NAV lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    NGEx Minerals will spin out its 1,090 sq. km Valle Ancho copper-gold district in the Maricunga belt into a new TSX Venture–listed company, with shareholders receiving 0.2 Spinco shares per NGEx share and funding provided for at least 12 months of exploration. Valle Ancho, fully owned since 2022, has porphyry copper-gold mineralisation confirmed by 2022 drilling and multiple drill-ready targets, yet contributes only about 1% (C$75 million) of NGEx’s estimated NAV. CEO Wojtek Wodzicki will lead Spinco, while NGEx refocuses on its Lunahuasi and Los Helados projects near the Chile-Argentina border.

    Technical Brief

    • Spin-out requires two-thirds shareholder approval at a Q4 meeting before TSX Venture listing.
    • Valle Ancho lies on the eastern flank of Chile’s Maricunga gold belt, extending into Argentina.
    • Pre-spin work includes systematic mapping, geophysics, geochemistry and a 2022 diamond drilling campaign.
    • 2022 drilling confirmed significant porphyry-style copper-gold mineralisation and delineated several drill-ready targets.
    • NGEx will fund Spinco for at least 12 months of exploration plus corporate overheads post-transaction.
    • Lundin family interests hold 36% of NGEx, anchoring funding access and deal-making capacity for Spinco.
    • Filo Mining, a prior NGEx spin-out, was acquired for about US$2.9 billion, illustrating re-rating potential for similar Lundin-led exploration vehicles.

    Our Take

    NGEx Minerals’ planned South American spinout centred on copper-gold ground such as Valle Ancho and the Vicuña District comes as our database shows continued strong drill results at Lunahuasi in Argentina (notably the Jupiter and Saturn zones), signalling that NGEx is trying to ring‑fence a coherent Andean exploration story for capital markets.

    With Valle Ancho accounting for only about 1% of NGEx’s estimated NAV yet sitting in the Maricunga–Vicuña copper-gold belt, the spinout structure effectively gives the Lundin Group a low-cost option on additional Andean discoveries without diluting the valuation of the more advanced Los Helados and Lunahuasi assets.

    The presence of BHP and Port Hedland iron ore metrics in the same coverage cycle underlines how NGEx’s copper-gold growth push in Chile and Argentina is unfolding against a backdrop where large diversified miners are still dominated by iron ore cash flow, which can later be redeployed into high-altitude copper projects if exploration success is proven.

    Glomar Minerals deep-sea push: Project Infinity schedule and design notes for engineers

    Glomar Minerals has sent its UK Seabed Resources vessel RV Tangaroa on a 67‑day campaign to the Clarion‑Clipperton Zone, surveying two UK‑sponsored licence areas totalling about 133,000 sq. km for polymetallic nodules rich in manganese, cobalt, nickel, copper and rare earths. CEO Chris Williams is targeting first processing of nodules before the end of Donald Trump’s current term via Project Infinity, a modular US refinery with Cobalt Blue designed for 200,000 tonnes of nodules and 7,500 tonnes of terrestrial cobalt hydroxide per year. The company is actively exploring regulatory pathways outside the ISA and positioning for staged scale‑up from a sub‑full‑vessel operation.

    B2Gold Mali permit and guidance cut: production and cost lens for mine planners

    B2Gold has secured the Menankoto exploitation permit for its Fekola Regional project in Mali, enabling pre-stripping and integration of regional ore with the existing Fekola complex, which is now expected to produce more than 150,000 oz. per year from 2028 into the mid‑2030s under a 65:35 ownership split with the state. The permit delay forced a cut to 2026 group guidance to 820,000–920,000 oz., while a fire‑damaged crushing circuit at the Goose mine has pushed all‑in sustaining costs there to $6,390/oz as B2Gold relies on mobile crushers ahead of restoring 4,000 t/d capacity. Despite lower guidance, group Q2 output of 203,648 oz. and AISC of $2,356/oz beat several bank forecasts, and the end of 264,768 oz. of gold prepayment deliveries should materially lift free cash flow from H2 2026.

    Gold miners’ 20% surge: valuation and project pipeline signals for engineers

    Gold’s jump of more than 2% on Friday to about $4,353/oz, after US payrolls unexpectedly fell by 23,000 in July, triggered one of the strongest weekly moves in years for gold equities. The VanEck Gold Miners ETF (GDX) surged 21.09% to $89.73 and the Junior Gold Miners ETF (GDXJ) 22.42% to $116.78, while Agnico Eagle, Newmont and Barrick each gained around 20% over five days. Junior-heavy TSX Venture names and the GDXJ outperformance underline how higher-cost producers’ operational leverage can rapidly reprice reserves and project pipelines.
