Focus Graphite Commissions WSP to Complete Air Dispersion Modelling and Dust Management Plan at Lac Knife
Press Release
Ottawa, ON, November 17, 2025 – Focus Graphite Inc. (TSX.V: FMS | OTCQB: FCSMF | FSE: FKC0) (“Focus” or the “Company”), a leading Canadian graphite developer advancing high-grade projects, is pleased to announce that it has commissioned an updated Air Dispersion Modelling and Dust Management Study (the “Study”) for its 100%-wholly owned Lac Knife Project (the “Project”) in Quebec. This work represents one of the final environmental studies required to complete the Environmental and Social Impact Assessment (“ESIA”) and advance the Project toward mine-permitting readiness.
The Study will be led by WSP Canada Inc. (“WSP”), a world-leading Montreal-based global engineering, environmental, and professional-services consultancy, and will be conducted under the supervision and management of IOS Geosciences Inc. (“IOS”), the Company’s geological consultant and general contractor for the Project. WSP includes the former Woods Engineering, which participated in the 2019 preliminary design of the dry-stack tailings storage facility (“TSF”), as well as Golder Inc., which conducted the original 2014 Study.
The Study will evaluate the potential airborne dispersion of dust and gases associated with mining operations, including:
- wind-driven erosion from the TSF,
- emissions generated by blasting activities, and
- traffic-related dust along the 7-kilometre access road linking Lac Knife to Highway 389.
This updated modelling replaces the earlier 2014 study to reflect the re-engineered dry-stack tailings design, developed as part of the 2021 Feasibility Study (the “Feasibility”) update. The redesign eliminates the former wet-pond configuration and instead utilizes dolomitic marble to amend and encapsulate tailings, thereby preventing acid mind drainage (“AMD”) and metal leaching. This new TSF concept was considered material enough to necessitate remodelling of the areal dispersion.
The current program directly addresses follow-up questions from Quebec’s Ministry of Sustainable Development, Environment, and the Fight Against Climate Change (“MDDELCC”), issued during its review of the Company’s 2014 ESIA submission. Results from the Study are expected by February 2026, aligning with the planned submission of the final revised ESIA.
“The completion of the air dispersion modelling and dust management plan marks one of the last major technical steps in our environmental review process,” said Dean Hanisch, Chief Executive Officer of Focus Graphite. “We are now systematically finalizing outstanding ESIA components to move Lac Knife toward the permitting stage. Each of these studies reflects our ongoing commitment to advance the Project responsibly.”
