    Vulcan Energy €2.2bn Lionheart lithium project: capex and schedule notes for engineers

    First reported on Mining Technology – News

    30 Second Briefing

    Vulcan Energy has secured a €2.2bn financing package, including €1.18bn in senior debt from 13 institutions, €204m in German Government grants and €528m from an equity raising at €2.24 per share, enabling a positive FID for phase one of its Lionheart lithium and geothermal project in Germany’s Upper Rhine Valley. Phase one targets 24,000 tonnes per year of battery-grade lithium hydroxide monohydrate from geothermal brines using Vulcan’s VULSORB adsorption-type DLE, plus 275GWh of power and 560GWh of heat annually over a 30-year life. Key infrastructure will include geothermal-lithium production wells, substations, pipelines, a renewable power and heat plant, a lithium extraction plant and a central lithium plant, with commercial output planned from 2028 and lithium offtake fully contracted for the first ten years.

    Technical Brief

    • Execution of phase one works is scheduled to commence within days of FID approval.
    • Construction and commissioning are funded end‑to‑end by the €2.2bn package, covering first-cash-flow stage.
    • Major EPC and supply contracts for phase one are largely executed, with remaining agreements targeted by year-end.
    • Lithium offtake is fully contracted with Europe-focused buyers for the first decade, de‑risking revenue during ramp‑up.

    Our Take

    Within our 140 Mining stories, only a handful of lithium pieces involve this level of multi-source backing from export credit agencies and public lenders, signalling that Lionheart in Germany’s Upper Rhine Valley is being treated more like strategic infrastructure than a conventional mine build.

    The 30‑year operational lifespan combined with 275 GWh of power and 560 GWh of heat for local consumers positions Lionheart as a baseload geothermal-heat supplier, which is likely to ease permitting and social licence constraints compared with greenfield lithium projects in less energy-constrained regions.

    KfW’s 14% stake in Vulcan Energie Ressourcen and the €204m in German Government grants effectively anchor the €2.2bn package, which should lower financing costs and could set a template for EU-backed lithium and battery raw material projects seeking similar blended public–private structures.

    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.
