Focus Graphite Commences Hydrogeological Study Supporting Redesigned Tailings System to Eliminate Mine Drainage at Lac Knife

One of the final studies required to complete the Environmental and Social Impact Assessment (ESIA) and advance toward mine permitting.

Ottawa, ON, November 10th, 2025 – Focus Graphite Inc. (TSX.V: FMS | OTCQB: FCSMF | FSE: FKC0) (“Focus” or the “Company”), a leading Canadian graphite developer advancing high-grade projects in Quebec, is pleased to announce the commencement of a hydrogeological study (the “Study”) at its wholly owned Lac Knife Project (the “Project”).

The Study will be executed by Yves Leblanc, P.Geo., of Richelieu Hydrogeologie Inc. (“RHI”), a Quebec based consulting firm specializing in groundwater management, mining and environmental hydrogeology, geothermal systems, and individual well design. RHI has supported Focus and the Lac Knife Project since 2019. The program will be carried out under the supervision and management of IOS Geosciences Inc. (“IOS”), the Company’s geological consulting firm and general contractor for the Lac Knife Project.

This Study represents one of the final major technical milestones in advancing the Company’s Environmental and Social Impact Assessment (“ESIA”) – a critical step toward the mine permitting phase for the Project. The hydrogeological program will characterize groundwater flows, aquifer properties, and potential interactions with Project infrastructure such as the open pit and tailings storage facility, ensuring responsible water management and full compliance with Quebec’s regulatory standards.

The Lac Knife deposit is located on a hillcrest between Knife Lake and Pecan River, both tributaries of the Moisie River, which is designated as a planned aquatic reserve. As such, the highest standards of aquifer protection must be applied. This Study aims to address concerns outlined in the second round of questions received in 2019 from Quebec’s Ministry of Sustainable Development, Environment, and the Fight Against Climate Change (“MDDELCC”) during its review of the Company’s original Environmental and Social Impact Study submitted in 2014. As part of the 2021 Lac Knife Feasibility

Study (“Feasibility”) update, the Project’s tailings storage facility was fully redesigned to incorporate nearby dolomitic marble, which will amend the tailings and eliminate the risk of acid mine drainage. This new design concept required a complete remodelling of the aquifer system. Results from the current hydrogeological modelling are expected by February 2026, aligning with the planned submission of the final ESIA revision.

Focus continues to collaborate with IOS to finalize contracting for the remaining studies, including tailings dam breach analysis and dust dispersion modelling.

“The launch of the hydrogeological study marks another important step toward permit readiness,” said Jason Latkowcer, Vice President, Corporate Development, Focus Graphite. “We are systematically closing out the final technical components of the ESIA—hydrogeological modelling being the most time-sensitive—ensuring that every environmental and social consideration is addressed with scientific rigour. Our commitment remains to advance Lac Knife responsibly, in alignment with Indigenous and Quebec environmental standards and the growing global demand for ethically sourced graphite.”

The Lac Knife Project hosts one of the highest-grade flake graphite deposits in the world, with measured and indicated resources grading 14.95% graphitic carbon (Cg). Once in production, Lac Knife is expected to supply high-purity graphite for defense, battery, and advanced materials markets, supporting Canada’s Critical Minerals Strategy.

On November 3, 2025 the Company announced that it had been selected by Natural Resources Canada (“NRCan”) under the Global Partnership Initiatives (“GPI”) for conditional approval for a non-repayable contribution of up to $14,062,500, pending final due diligence.
