Graphite One Alaska–Ohio supply chain: design and capex notes for mine planners
Reviewed by Tom Sullivan

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.
