A milestone in the environmental studies advancing the wholly-owned Quebec graphite project toward future permitting.
The Air Quality Assessment (AQA) for the Lac Knife Graphite Project in northeastern Quebec was completed by WSP Canada Inc., under the supervision and management of IOS Geosciences Inc., as part of the environmental work program advancing the project toward permitting readiness.
Focus described the assessment as another step in the environmental studies required to support future permitting and development at Lac Knife, which it owns outright.
Air quality and atmospheric dispersion modelling are required components of Quebec’s environmental review process, and their completion is a prerequisite for the broader environmental and social impact assessment (ESIA) that underpins mine permitting in the province.
Graphite is classified as a critical mineral for the energy transition, and supply outside China remains limited. Lac Knife is among the more advanced high-grade flake graphite projects in North America, positioned as a potential supplier to battery, defence and industrial markets.
The Announcement
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 what the company described as conservative maximum operating scenarios.
Atmospheric dispersion modelling was carried out using Aermod software, in accordance with the requirements of Quebec’s Reglement sur l’assainissement de l’atmosphere and applicable guidance from the provincial environment ministry (MELCCFP).
According to WSP’s conclusions, the modelling results indicate that predicted contaminant concentrations remain in compliance with applicable Quebec ambient air quality standards and criteria under the assessed operating conditions, and that all evaluated contaminants met applicable regulatory thresholds.
The Study assessed a range of potential emissions, including particulate matter, nitrogen oxides, sulphur dioxide, carbon monoxide, crystalline silica and various metals, using an atmospheric dispersion model based on five years of regional meteorological data. The company said prevailing winds were modelled as 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. 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.

What Comes Next
The company said the AQA forms part of the broader environmental and permitting work program at Lac Knife and represents a milestone toward completion of the ESIA process.
With the Study complete, Focus said it is advancing the remaining key environmental workstreams:
- A hydrogeological assessment, characterising groundwater conditions around the proposed site.
- A dam breach analysis for the tailings storage facility.
The company expects both will further support permitting activities and future project development.
The Project
Lac Knife is the more advanced of Focus Graphite’s two wholly-owned graphite projects in Quebec’s Côte-Nord region. The figures below are drawn from the company’s previously disclosed feasibility study update and resource estimates.
Resource and project figures are as previously announced by the company and remain subject to feasibility, permitting and funding workstreams. Mineral resources are reported at a 4.0% Cg cut-off for Lac Knife.
Background
Focus Graphite, which trades on the TSX Venture Exchange under the symbol FMS, describes itself as a Canadian developer of high-grade flake graphite deposits and advanced graphite materials for battery, defence and industrial applications. The company also reports work on downstream battery materials, including a patent-pending silicon-enhanced spheroidized graphite.
The technical content of the announcement was reviewed and approved by Rejean Girard, P.Geo., President of IOS Geosciences Inc. and a qualified person under National Instrument 43-101.
The company noted that statements regarding future permitting, the timing of remaining environmental studies and the future development of the project are forward-looking, and that actual results may differ.
