WSP Air Quality Assessment Confirms Regulatory Compliance and Further Advances Lac Knife Toward Permitting and Construction Readiness

Ottawa, Ontario - Newsfile Corp. - June 8, 2026 - Focus Graphite Inc. (TSXV: FMS) (OTCQB: FCSMF) (FSE: FKC0) ("Focus" or the "Company") a Canadian developer of high-grade flake graphite deposits and advanced graphite materials for battery, defence, and industrial applications, is pleased to announce the completion of the. Air Quality Assessment ("AQA" or the "Study") for its 100%-owned Lac Knife Graphite Project (the "Project") located in northeastern Quebec.

The Study was completed by WSP Canada Inc. ("WSP"), one of the world's leading engineering and environmental consulting firms, under the supervision and management of IOS Geosciences Inc. ("IOS"), as part of the environmental studies supporting the advancement of Lac Knife toward future permitting and development.

The AQA evaluated emissions associated with the proposed open pit mine, processing facility, tailings storage facility, stockpiles, haul roads, crushing operations, and supporting infrastructure under conservative maximum operating scenarios. Atmospheric dispersion modelling using Aeromod software, was completed in accordance with the requirements of Quebec's Reglement sur l'assainissement de l'atmosphere ("RAA") and applicable guidance from the Ministere de l'Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs ("MELCCFP").

According to WSP's conclusions, the modelling results demonstrate that predicted contaminant concentrations remain in compliance with applicable Quebec ambient air quality standards and criteria under the assessed operating conditions. WSP further concluded that all evaluated contaminants met applicable regulatory thresholds. The Study also noted that prevailing winds are predominantly directed toward the south-southeast, away from nearby public infrastructure, residences, and seasonal fishing cabins.

"Environmental permitting is one of the most important value-creation stages in the development of any critical mineral project," said Dean Hanisch, CEO of Focus Graphite. "The completion of the Air Quality Assessment represents another key component of the broader environmental review process and brings us closer to completing the environmental studies required to support future permitting activities. As these workstreams are completed, Lac Knife continues to become increasingly de-risked from both a technical and environmental perspective while strengthening its position as a strategic North American graphite asset."

The Study evaluated a broad range of potential emissions, including particulate matter, nitrogen oxides, sulphur dioxide, carbon monoxide, crystalline silica, and various metals, using a detailed atmospheric dispersion model of the Project area and surrounding receptors based on five years of regional meteorological data.

Advancing Toward Environmental Assessment Completion

The AQA forms part of the broader environmental and permitting work program being advanced at Lac Knife and represents another important milestone toward completion of the environmental and social impact assessment ("ESIA") process. With this Study now complete, the Company is advancing the remaining key environmental workstreams, including the hydrogeological assessment and dam breach analysis, which are expected to further support permitting activities and future project development.

The completion of the AQA builds on a series of technical, environmental and infrastructure achievements that continue to de-risk the Project and strengthen Lac Knife's position as a strategically important North American graphite asset. As demand for secure and reliable graphite supply continues to grow, Focus remains focused on advancing the Project through the key milestones required for future development.
