    Lithium’s $100B, 134‑mine build‑out: project pipeline risks for mine planners

    Lithium’s $100B, 134‑mine build‑out: project pipeline risks for mine planners

    First reported on MINING.com

    30 Second Briefing

    Global lithium demand is projected by Benchmark Mineral Intelligence to reach nearly 7 million tonnes LCE by 2050, up from 2.11 million tonnes this year, requiring the equivalent of 134 new mines at an average 36,000 t/y capacity and over $100 billion in capital. Australia’s share of mined supply is expected to fall from 29% to 20% as operations deplete, while North America could rise from 1.7% to 13% and Europe to 5.5%, both constrained by permitting, unproven extraction technologies and community opposition. Benchmark assumes recycling could supply almost half of lithium by mid-century, yet timing of battery retirements and cost competition with new mines remain critical uncertainties for project financing and long‑term supply planning.

    Technical Brief

    • EVs’ share of lithium demand is projected to rise from 55% today to 76% by 2050.
    • Stationary energy storage demand has grown >60% annually for two years, then moderating to ~5%/y to 2030.
    • Batteries already consume 92% of lithium, up from ~70% in 2020, tightening non-battery supply availability.
    • Benchmark’s upside scenario to ~9 Mt LCE by 2050 would need ~180 mines and >$150 billion capex.
    • Capex requirement to 2040 is estimated at ~$64 billion, assuming recycling supplies a substantial demand share.
    • Recycling growth is constrained by end-of-life timing; every shortfall tonne must be substituted by primary mining.

    Our Take

    Benchmark Mineral Intelligence also underpins our recent coverage of uranium and copper supply gaps, signalling that its projection of 134–180 new lithium mines by 2050 is part of a broader pattern of structural tightness across multiple energy-transition commodities rather than a lithium-only outlier.

    The forecast jump in North America’s mined lithium share from 1.7% to 13% by 2050 aligns with US Department of Energy funding activity in our database, suggesting that midstream policy tools (grants, tax credits, offtake support) will be as critical as greenfield permitting in closing the region’s supply–demand gap.

    With recovered material expected to provide about half of lithium supply by mid‑century, the capex estimate of $64 billion to 2040 under substantial recycling implies that projects in regions like Europe, which currently contribute under 1% of mined supply, may lean heavily on recycling and conversion capacity rather than large new greenfield mines.

    Fortuna’s deeper Lindero pit pushback: design and scheduling notes for engineers

    Fortuna Mining is evaluating a deeper pushback at its Lindero open pit in Argentina’s Puna after hole LDH-272 cut 350 m at 0.96 g/t Au from surface, including 98 m at 0.91 g/t below the current pit design, with LDH-259 returning 236 m at 0.85 g/t and 94 m below-pit at 0.66 g/t. Both below-pit intervals exceed the 0.54 g/t reserve grade for Lindero’s 64.4 Mt proven and probable heap-leach reserves, currently supporting a nine-year mine life and 92,000–102,000 oz/y guidance. Fortuna has expanded 2026 diamond drilling to 8,534 m in 31 holes and plans updated resource, reserve and pit designs in Q1 next year, which could materially alter strip ratios, slope configurations and long-term scheduling.

    Stöferle on gold bargains and 40% cash: capital discipline insights for mine teams

    Liechtenstein-based Incrementum gold fund manager Ronald-Peter Stöferle told The Northern Miner at Mining Forum Americas in Colorado Springs that his active gold strategy is holding almost 40% cash after its investment signal turned defensive earlier this year, yet he now sees clear bargains in mining equities following gold’s recent pullback. Meetings with producers convinced him that majors are showing unusual capital discipline on M&A and project pipelines despite rising earnings. He expects generalist investors to increase gold allocations, expanding the capital pool for listed miners.

    Belo Sun’s $300m Volta Grande halt: permitting and ESG risks for mine planners

    Brazil’s Supreme Federal Court has again halted Belo Sun Mining’s $300 million Volta Grande project in Pará, suspending the installation licence until a settlement with the National Foundation of Indigenous Peoples (Funai) is judicially approved. The ruling centres on incomplete Indigenous Component Studies and cumulative environmental risks in a region already impacted by the Belo Monte hydroelectric dam, with Justice Edson Fachin warning of “serious harm” given the project’s exceptional scale. The delay stalls development of a planned 17-year open-pit mine with 3.8 million oz in reserves and projected output of about 205,000 oz of gold per year.
