First Canadian Graphite Partner Receives Patent Allowance, Achieves Graphene Development Milestones

Montreal, Quebec — October 3, 2025 — Leads & Copy — First Canadian Graphite Inc. (TSX-V: FCI, FSE: BK20) announced that its partner, Volt Carbon Technologies Inc., has received a Notice of Allowance for a continuation of its U.S. patent on proprietary air classifier technology. Volt Carbon has also achieved milestones in graphene development.

The announcement builds on a Preliminary Mineral Processing Agreement signed June 5, 2023, between First Canadian Graphite (formerly Green Battery Minerals) and Volt Carbon Technologies. Volt Carbon Technologies Inc. (TSX-V: VCT) (OTCQB: TORVF) highlighted two milestones in its October 2, 2025 news release: successful production and verification of reduced graphene oxide (rGO) sheets from Berkwood flake graphite, delivering 40–60% improved mechanical properties when mixed into epoxy resin, and expanding protection for Volt Carbon's air classifier technology, enhancing graphite processing efficiency and advanced material applications.

Volt Carbon's patent and graphene achievements used graphite from First Canadian Graphite's Berkwood project, confirming the quality and suitability of the Company's deposit for advanced processing and next-generation applications. Reduced Graphene Oxide (rGO) is an advanced material derived from natural graphite that combines the ease of processing graphene oxide with many of the properties of pure graphene, making it attractive for applications in batteries, energy storage, aerospace composites, and advanced materials.

Tom Yingling, President & CEO of First Canadian Graphite, stated that the production of reduced graphene oxide (rGO) using graphite from the Berkwood project validates the quality of their resource and demonstrates its potential for high-value applications such as batteries, aerospace composites, and advanced materials.

The Berkwood Graphite Project is located in Quebec, accessible via a major secondary road and numerous tertiary and forest roads. The Zone 1 resource is located 8 km southwest of Nouveau Monde’s deposit. The current mineral resource at the Berkwood Graphite Project includes 1,755,300 tonnes of indicated resources at 17.00 % Cgr and 1,526,400 tonnes in inferred resources at 16.39 % Cgr.
