    Newmont’s Lihir gold mine barrier plan: production and capex lens for engineers

    Newmont’s Lihir gold mine barrier plan: production and capex lens for engineers

    First reported on MINING.com

    30 Second Briefing

    Newmont expects a planned nearshore barrier at the Lihir mine in Papua New Guinea’s New Ireland Province to unlock more than 5 million oz of additional gold from 2028, while reaffirming 2026 production guidance after Q2 output of 1.3 million oz of gold, 17,000 tonnes of copper and 7 million oz of silver. Q2 cash flow from operations reached $2.9 billion and free cash flow hit a record $2.2 billion, with all-in sustaining costs of $1,621/oz against a $1,680/oz guidance and an average realised gold price of $4,414/oz. Management also reported regulatory progress at the Red Chris block cave in British Columbia and resumed cave production at Cadia in Australia, but flagged higher sustaining capital in Q3 and rising capital estimates at Red Chris.

    Technical Brief

    • Newmont links the barrier with improved mining stability and lower operating costs at Lihir.
    • Management reports “greater mining stability” at Lihir, implying more consistent geotechnical and hydrological conditions in pit.
    • Regulatory approvals for the Red Chris block cave in British Columbia are advancing towards feasibility and board sanction.
    • Capital costs at Red Chris are now expected to exceed earlier Newcrest estimates, signalling higher block cave development intensity.
    • Cadia’s operating caves in Australia resumed production in mid-June after an April seismic event.
    • Ahafo North, Cerro Negro, Tanami and Boddington are grouped with Lihir as core long-term growth assets.
    • Investor questioning focused on oil price exposure, Ghana policy risk and Red Chris capital escalation.

    Our Take

    With gold holding above the $4,000/oz support level in the 20–23 July price pieces in our database, a 5‑million‑ounce uplift at Lihir in Papua New Guinea positions Newmont as one of the few majors able to leverage current high prices with genuine volume growth rather than just margin expansion.

    The strong second‑quarter free cash flow and $1.9 billion already returned to shareholders suggest Newmont has more flexibility than many gold peers flagged in recent price coverage (e.g. Barrick, Agnico Eagle, Kinross) to fund nearshore barrier works at Lihir while still advancing capital‑intensive projects like Red Chris block cave and Tanami.

    Newmont’s activity in Canada spans both growth (Red Chris, Cadia‑style block caving) and portfolio pruning, as seen in the Mule Canyon divestment to Central Nevada Gold on 16 July, signalling a strategy of concentrating capital on large, long‑life gold–copper systems rather than smaller standalone gold assets.

    McEwen’s $55M Ontario asset sale: production growth lens for mine planners

    McEwen has agreed to sell its Fuller and Paymaster gold properties in Ontario’s Timmins district to Discovery Mining for $55 million in cash and stock, freeing capital to push a production target of 250,000–300,000 gold-equivalent ounces per year by 2030. The deal covers 210 hectares at Fuller, a 60% stake in the 179-hectare Paymaster property, and associated surface rights, consolidating Paymaster under Discovery’s Dome Mine subsidiary. Proceeds will be reinvested into the Fox Complex (Froome, Stock, Grey Fox), Nevada’s Gold Bar Complex, and Mexico’s El Gallo build, with Stock Mine slated for first ore in Q4 2026 and commercial output in Q1 2027.

    Lithium Triangle extraction hurdles: hydrogeological insights for project teams

    South America’s Lithium Triangle holds about 64 million tonnes of identified lithium resources (43% of the global 150 million tonnes), yet geologist José Cabello’s review of 43 salt flats across Argentina, Bolivia and Chile shows that variable brine chemistry, impurities and groundwater behaviour make recovery and costs highly site-specific. Salar de Atacama benefits from ultra‑dry climate, relatively clean brines and strong logistics, while other basins such as Altoandinos, Pedernales, Hombre Muerto Oeste, Rincón, Sal de los Ángeles and Sal de Vida face tighter water and hydrogeological constraints. Direct lithium extraction (DLE) could unlock lower‑grade or impurity‑rich brines, but Cabello stresses that trade‑offs between brine withdrawal and freshwater consumption mean technology selection must be tailored to each basin’s hydrology and ecosystem.

    KGHM’s $2.4bn copper projects fast-tracked: CRMA implications for mine planners

    EU regulators have granted strategic status under the Critical Raw Materials Act to KGHM’s 9.5‑billion‑zloty ($2.44bn) Retków‑Grodziszcze mine and Legnica smelter conversion, unlocking faster permitting, streamlined administration and access to preferential financing. Retków‑Grodziszcze is planned to deliver over 100 million tonnes of ore by 2055, yielding about 1.5 million tonnes of copper and 5,000 tonnes of silver, while Legnica’s recycling line targets 135,000 tonnes of electrolytic copper and 250 tonnes of nickel per year. The move materially boosts EU copper and nickel recycling capacity, central to the CRMA’s 25% recycling target.
