    Graphite One Alaska–Ohio supply chain: design and capex notes for mine planners

    Graphite One Alaska–Ohio supply chain: design and capex notes for mine planners

    First reported on MINING.com

    30 Second Briefing

    Graphite One has secured a Conneaut, Ohio site from Bessemer and Lake Erie Railroad (CN subsidiary) for its Active Anode Materials facility, gaining direct Lake Erie port access, multi-line CN rail, an on-site substation and room to scale. The staged build-out targets an initial 25,000‑tonne module, ultimately 100,000 tonnes per year of anode material, supplied by the post‑feasibility Graphite Creek deposit in Alaska with a planned 20‑year mine life and backed by up to US$2 billion in potential EXIM funding. A separate Ohio finishing and blending plant aims for Q4 2027 completion with 10,000 t/y initial capacity, split into 4,000 t energy storage, 3,000 t fast‑charging and 3,000 t high‑energy‑density graphite products for lithium‑ion batteries.

    Technical Brief

    • Licence of occupation with Bessemer and Lake Erie Railroad secures long-term industrial site control in Conneaut.
    • Direct CN multi-line rail and Lake Erie berth enable bulk concentrate import and finished product export.
    • Existing on-site electrical substation reduces initial capex for power distribution and grid interconnection works.
    • US EXIM potential funding increase to >US$2 billion underpins Alaska–Ohio integrated mine-to-anode capex envelope.
    • Graphite Creek is described by USGS as the largest graphite deposit in the US, supporting long-term feed security.
    • Graphite Creek has advanced to post-feasibility and is proceeding through FAST-41 permitting, shortening federal review timelines.
    • Ohio finishing and blending plant is one of three processing facilities within the overall Active Anode Materials complex.
    • Phase One output split (4,000 t storage, 3,000 t fast-charge, 3,000 t high-energy-density) targets differentiated Li-ion battery niches.

    Our Take

    The related 19 December 2025 piece on EXIM’s roughly $2.1 billion potential financing for the Alaska‑to‑Ohio graphite chain signals that Graphite One’s current site decision in Ohio is being made with an unusually clear line of sight to US-backed project finance compared with most battery-materials projects in our database.

    The combination of graphite, uranium and rare earth metals around Graphite One and associated entities like AML mirrors a small cluster of US critical-mineral stories in our database where multi-commodity exposure is being used to appeal to defence and energy-security funding streams rather than relying solely on EV-battery demand.

    2026 Australian Mining Prospect Awards: networking and project angles for engineers

    Tickets are now on sale for the 2026 Australian Mining Prospect Awards gala dinner, to be held on 16 September 2026 at Fraser’s Kings Park in Perth. The event will bring together mining professionals, contractors, OEMs and executives from across Australia to recognise finalists across multiple operational, innovation and ESG-focused award categories. Attendance offers operators, engineers and suppliers a concentrated networking opportunity with project decision-makers ahead of 2027 investment and tender cycles.

    FireFly’s Green Bay project economics: NPV, IRR and capex lens for mine planners

    FireFly Metals’ Green Bay copper-gold project in Newfoundland now carries an after-tax NPV of A$2.2 billion (C$2.1 billion) at a 7% discount rate and a 42% IRR, with initial capital of A$513 million, giving more than four times NPV-to-capex leverage and planned throughput of 1.8 million tonnes per year over 32 years. Updated measured and indicated resources stand at 60.2 million tonnes grading 1.9% Cu, 0.5 g/t Au and 4.2 g/t Ag, containing 1.1 million tonnes Cu, 908,000 oz Au and 8.1 million oz Ag after 69,539 metres of underground drilling. A feasibility study is targeted for Q1 2027, with a final investment decision in H2 2027 and first concentrate potentially in mid-2029, backed by a proposed A$180 million equity raise split between an ASX institutional placement and a Canadian bought deal.

    Waratah’s new shallow high-grade Consols gold zone: pit design notes for planners

    Waratah Minerals has extended the Consols gold system at its Spur project in New South Wales by 75m to the east and down-plunge, while identifying a new shallow high-grade zone. Step-out hole SPD074 intersected 12.7m at 1.35g/t gold from 44m downhole, defining a near-surface target with open extensions. For mine planners and geotechnical teams, the shallow geometry and incremental strike extension suggest potential for low-strip open-pit designs and simplified access for infill drilling and geotechnical characterisation.
