Green Graphite Technologies (GGT) and Weaver Energy have finalised a supply agreement for graphite concentrate, marking a major step toward onshoring graphite production for North American EV batteries.
GGT will use the material to produce battery-grade graphite using its GraphPure process, which boasts a 50% cost reduction and 82% fewer greenhouse gas emissions compared to hydrofluoric acid-based methods. The company’s demonstration facility will launch in Kingston, Ontario, in Q1 2026, with a commercial plant targeted for 2029. GGT is currently seeking US$7 million in funding to complete this phase.
Weaver Energy, owner of the Black Crystal mine in British Columbia, benefits from regolith-hosted graphite, which allows for lower-energy processing. With its production-ready concentrator near the site, the company is positioned to supply North American-sourced anode materials for EVs.
Gillian Holcroft, co-founder and CEO of GGT, said, “The automobile OEMs and the battery cell manufacturers are all seeking a vertical alignment of their supply chain for battery materials, often referred to as Rock to Road. This first agreement with a North American-based graphite mine supports the domestic securing of the anode active material supply chain for lithium-ion batteries. GGT’s proprietary, low carbon footprint, cost-effective technology enables the onshoring of midstream processing, a matter of high importance for national security and energy security for the West.”
Greg Gibson, CEO of Weaver Energy added: “Our Black Crystal Graphite Project in British Columbia is a unique operation in that a significant amount of the resource consists of graphite contained in regolith (sand). This blend eliminates the requirement for drilling, blasting or crushing. Given the nature of the Regolith deposit, there are no tailing concerns as the sand by-product is sold as sand and aggregate. Partnering with GGT will provide an opportunity to have North American-sourced natural graphite to be used in North American EVs. This collaboration offers what could be the lowest carbon footprint, most environmentally-sound graphite in the industry.”
