FIRST CANADIAN GRAPHITE MOBILIZES FIELD CREWS TO LAC GUERET SOUTH - TARGETING NEW KILOMETRE-SCALE ANOMALY AND HIGH-GRADE ZONES

First Canadian Graphite Inc. has commenced field exploration activities at its flagship Lac Gueret South project in Quebec's Cote-Nord region. A strong technical team is now on the ground executing the 2026 program, with immediate focus on high-priority targets identified in the recent airborne EM (electromagnetic) and magnetic survey.

Field crews have mobilized to explore zone 13, a newly identified kilometre-scale electromagnetic anomaly, as well as zone 1, zone 4 and zone 6, the latter of which has returned high-grade graphite intercepts in previous drilling. This aggressive surface campaign follows the company's June 16, 2026, announcement outlining the two-phase program and builds directly on the highly encouraging heliborne geophysical results that highlighted multiple untested and partially tested conductors across the large land package.

"We are excited to have our team in the field and advancing our most promising targets," said John LaGourgue, First Canadian Graphite's chief executive officer. "Zone 13 represents a compelling new discovery opportunity with significant scale potential, while zones 1, 4 and 6 allow us to build on known high-grade graphite mineralization. The data and samples collected in the coming weeks will refine our understanding of these systems and fast-track the selection of drill targets for our planned 2026 fall diamond drilling campaign. This is a pivotal step in unlocking the district-scale potential of Lac Gueret South in a Tier 1 jurisdiction."

Program highlights and next steps:

• Beep Mat ground-truthing, prospecting and geological mapping to delineate surface expressions of the EM conductors;
• Systematic grab sampling and structural analysis to evaluate graphite grades, widths and orientations;
• Priority advancement of the highest-potential zones to be mechanically stripped and channel sampled later in the fall during rig mobilization to optimized drill hole locations;
• Results from this work will directly inform a maiden or expanded resource drilling program scheduled for late fall 2026.

The Lac Gueret South project (formerly Berkwood) covers a substantial land position in the Manicouagan region, strategically located near the world-class Uatnan (formerly known as Lac Gueret) graphite deposit. Graphite remains a critical mineral essential for the energy transition, with strong demand drivers in battery anode materials and North American supply chain security.

About First Canadian Graphite Inc.

First Canadian Graphite is engaged in the exploration of critical minerals and is committed to advancing its Lac Gueret South high-grade graphite property to support applications in energy transition and advanced technologies.

The Lac Gueret South project, formerly known as the Berkwood project, borders Nouveau Monde Graphite's Uatnan graphite project in the southwest Manicouagan reservoir area, 234 kilometres north-northwest of Baie-Comeau, in the Cote-Nord administrative region of Quebec on the Nitassinan (ancestral territory) of the Pessamit Innu. Lac Gueret South features surface-exposed graphite and a historical NI 43-101-compliant resource at zone 1 containing 1.76 million tonnes indicated at 17 per cent Cg and 1.53 million tonnes inferred at 16.4 per cent Cg. The property also features several other zones with surface graphite samples, offering strong exploration potential. In early 2026, the company increased its land holdings to 167 square kilometres, establishing one of the most extensive claim portfolios within the Lac Gueret graphite district. With substantial exploration opportunities remaining and total investments exceeding $10-million, First Canadian Graphite is actively engaged in expanding its resources and advancing toward the completion of its preliminary economic assessment (PEA). The company possesses sufficient financing to further advance this project throughout 2026.

Pessamit Innu First Nation engagement

First Canadian Graphite formally acknowledges that the Lac Gueret South project is situated within the Nitassinan (ancestral territory) of the Pessamit Innu First Nation. The company remains dedicated to cultivating respectful, transparent and co-operative relationships with local indigenous communities at every stage of the project's development.
