    Titan Mining’s Kilbourne graphite plant: scale-up and funding lens for mine planners

    Titan Mining’s Kilbourne graphite plant: scale-up and funding lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    Ore feeding has begun at Titan Mining’s Kilbourne graphite demonstration plant in St. Lawrence County, New York, a fully permitted facility designed to produce 1,200 tonnes per year of graphite concentrate within the existing Empire State Mine complex and 5,000 t/d mill. The start-up will supply micronised and high-purity natural flake graphite from the Kilbourne deposit for qualification runs and offtake talks, underpinning plans for a 40,000 t/y commercial plant targeted to supply roughly half of current US natural graphite demand. Titan has secured an extra $5.5 million in EXIM funding and a non-binding Letter of Interest for up to $120 million in project finance, with a construction decision expected by end-2026.

    Technical Brief

    • Ore feeding has begun into the Kilbourne demonstration circuit, initiating commissioning of the graphite flowsheet.
    • The plant is integrated within Titan’s existing Empire State Mine complex, leveraging the operating 5,000 t/d mill site.
    • Kilbourne graphite mineralisation currently has a tested strike length of 2,500 m within a 7,620 m known trend.
    • EXIM’s additional US$5.5 million non-dilutive funding is earmarked to accelerate feasibility and detailed engineering work.
    • A non-binding EXIM Letter of Interest covers up to US$120 million in potential project finance for commercial-scale build-out.
    • Titan acquired the Empire State asset package, including six historic mines and the mill, out of bankruptcy in 2018, providing brownfield foundations for graphite development.

    Our Take

    EXIM’s non-dilutive support for Titan Mining’s Kilbourne graphite demonstration facility sits at the upper end of what our database shows for early-stage US critical mineral projects, signalling that federal export-credit style backing is now being used as a quasi-project finance bridge for domestic supply chains.

    With graphite and zinc both tagged in our coverage but only a handful of graphite-focused US pieces, Titan’s ability to leverage the existing Empire State Mine infrastructure just 1 mile from the Kilbourne deposit likely gives it a cost and permitting advantage over greenfield US graphite entrants starting from scratch.

    The 70‑year gap since domestic graphite deliveries to US customers underscores that any successful ramp-up at the Kilbourne graphite plant could quickly become a reference case for other North American flake graphite projects, including Canadian assets such as Northern Graphite’s Lac des Iles mine looking to secure US offtake and financing support.

    EnergyX enters nuclear materials market: isotopes, Smackover project lens for mine planners

    Energy Exploration Technologies (EnergyX) has launched its NUKE-it platform to produce nuclear-grade lithium isotopes, targeting 15% enriched Lithium-6 for tokamak fusion and 99.999% pure Lithium-7 for thorium molten salt fission reactors. Building on its GET-Lit DLE extraction and refining suite, the company is tying isotope production to its Lonestar Lithium project in the Smackover formation, where it now controls 47,500 acres of lithium-rich brine after a US$26 million land deal. Uranium and thorium materials from upper Smackover limestone reservoirs in Arkansas and Louisiana are planned as follow-on products.

    America can’t defend itself with Chinese minerals: offshore supply lens for mine planners

    America’s near-total reliance on China for critical minerals – including 90% of global rare earth magnets, all ultrapure dysprosium and samarium for defence uses – is framed by NOIA president Erik Milito as a direct national security risk. Milito backs President Trump’s “Unleashing America’s Offshore Critical Minerals and Resources” executive order to fast-track offshore exploration, arguing that polymetallic nodules and shallow-water deposits could supply nickel, cobalt, manganese and copper at multi-generational scale. He points to decades of US sediment dredging and modern offshore robotics, monitoring and containment as evidence that well-regulated seabed mining can be run with controlled environmental impacts.

    Hancock–Maaden Saudi JV: exploration and project delivery lens for mine planners

    Hancock Prospecting and Saudi state miner Maaden have formed a joint venture to run exploration, development, mining, sales and marketing across licensed areas in Saudi Arabia, including five new exploration licences in the Nabita Ad-Duwayhi Gold-Belt. The partnership, announced alongside Round 9 licence awards at the Future Minerals Forum in Riyadh on 14 January, aims to accelerate discovery and project delivery under the Kingdom’s Vision 2030 pro-mining framework. Hancock brings large-project experience from Australia’s A$10 billion Roy iron ore project, while Maaden targets rapid build-out of a regional mineral hub and local talent pipeline.
