Graphite One Clears Key Ohio EPA Hurdle for Planned Ohio Battery Materials Facility
Air permit application accepted as preliminarily and administratively complete, advancing G1’s Ohio processing facility into technical review
VANCOUVER, BC, July 16, 2026 /PRNewswire/ — Graphite One Inc. (TSXV: GPH) (OTCQX: GPHOF) (“G1“, “Graphite One” or the “Company“), a developer of a complete U.S.-based advanced graphite supply chain, today announces another significant milestone in the development of its planned Active Anode Materials (“AAM“) facility in Conneaut, Ohio. The Ohio Environmental Protection Agency (“Ohio EPA“) has determined the Company’s air permit application is complete and has commenced technical review.
Acceptance into technical review represents a key milestone in the Ohio permitting process and confirms the Ohio EPA has determined the application contains the information required to begin its detailed technical review, an important step toward issuance of the required air permit.
Mike Schaffner, Chief Operating Officer, said:
Acceptance into technical review reflects the quality of the work completed by G1’s engineering and permitting teams,
“We appreciate Ohio EPA’s review and remain focused on advancing the project efficiently toward construction.”
The planned Conneaut facility is designed to produce synthetic AAM, a critical battery material used in lithium-ion batteries for electric vehicles, grid-scale energy storage, and other applications. The initial phase is expected to produce approximately 10,000 tonnes per year, with planned expansion to 25,000 tonnes per year. Graphite One’s non-linear development strategy allows the Ohio facility to move to production independently of the Company’s Graphite Creek Project near Nome, Alaska, creating an earlier path to revenue than in traditional resource development projects.
Together, the Company’s planned Graphite Creek project in Alaska and planned Ohio AAM facility are designed to establish the first fully integrated domestic U.S. graphite supply chain—from mining graphite in Alaska to producing advanced battery materials in Ohio. This vertically integrated strategy is intended to strengthen U.S. manufacturing competitiveness, reduce reliance on foreign supply chains, and improve long-term supply chain resilience.
This milestone further advances the Company’s integrated U.S. graphite supply chain and complements ongoing permitting progress at the Graphite Creek project in Alaska. Subject to permitting, regulatory approvals, and financing, synthetic AAM production is expected to commence at the Ohio facility in Q4 2027, with natural graphite production at Graphite Creek targeted for 2029.
This milestone follows a series of important project advancements throughout 2026 as Graphite One continues executing engineering, permitting, procurement, financing, and customer engagement activities on both of its Alaska and Ohio projects.
Anthony Huston, President, & CEO, said:
Today’s milestone is another demonstration of the disciplined execution of our strategy to build the first fully integrated domestic U.S. graphite supply chain,
“Every permitting, engineering, financing, and customer engagement milestone reduces execution risk and moves us closer to commercial production. Together, these parallel workstreams strengthens Graphite One’s position as a strategic domestic supplier of advanced graphite materials supporting America’s battery and energy storage industries. We remain focused on achieving additional project milestones throughout 2026 while creating long-term value for our shareholders, customers, and strategic partners.”
