FIRST CANADIAN GRAPHITE REPORTS ENCOURAGING RESULTS AT LAC GUERET SOUTH FROM AIRBORNE SURVEY INDICATING SIGNIFICANT EXPANSION POSSIBILITIES

First Canadian Graphite Inc. has received positive results from an airborne time-domain electromagnetic (TDEM) and magnetic survey conducted, completing 857 line-kilometres across seven priority zones at the company's Lac Gueret South property, located 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. The results outlined numerous conductive high-priority anomalies and favourable geological conditions across all seven surveyed blocks.

About Lac Gueret South

The Lac Gueret South high-grade graphite project (formerly the Berkwood graphite district) in Quebec borders the Uatnan graphite deposit of Nouveau Monde. It features surface-exposed graphite and an NI 43-101 resource at Zone 1 containing:

• 1.76 million tonnes indicated at 17 per cent graphitic carbon (Cg);

• 1.53 million tonnes inferred at 16.4 per cent Cg.

Summary of airborne survey results by zone:

• Zone 1: Numerous TDEM anomalies identified, as well as the strongest magnetic anomaly located. Conductive lineaments generally correlate with high magnetics.

• Zone 3: High magnetics with numerous TDEM anomalies.

• Zone 4: Highest density of TDEM anomalies characteristic of graphite and sulphide conductors in the bedrock.

• Zone 5: Numerous TDEM anomalies, including a notable cluster associated with folded linear features.

• Zone 6: Numerous TDEM anomalies, mostly trending northwest-southeast, with significant deformation and folding noted, particularly in the southeast.

• Zone 9: The area displays several magnetic lineaments, with some conductive sources showing positive correlation with magnetic features.

• Zone 13: The survey revealed complex magnetic patterns and several high-conductance targets.

The survey used both high-sensitivity magnetic sensors and TDEM technology to find conductive materials like graphite or sulphides. Magnetic data helps map geological formations and their structural context. Because graphite conducts electricity effectively, electromagnetic (EM) surveys are especially useful for locating potential graphite mineralization in this environment.

The data collected during the survey is currently being modellized and interpreted by Marc Auclair of Baseline Geophysics. In parallel, the company initiated a regional-scale compilation of public data available through the MRNF as well as of the data collected by previous management from the last decade of exploration work. This compilation will serve as the base for the preparation of a geological mapping and hammer prospecting program planned for the summer of 2026. In the fall of 2026, the company will launch its first diamond drilling program on the most promising surface and modellized graphitic targets, as soon as drill permits have been obtained.

"These survey results from Lac Gueret South are very encouraging, with conductors identified throughout all zones within our claim area," said John LaGourgue, First Canadian Graphite's chief executive officer. "Not only do we see potential for expansion at Zone 1, but also across six additional high-priority zones. This information will now be used to plan our fully funded summer exploration program, which we look forward to starting in the coming weeks."

Technical survey specifications

The survey used an Airbus H125 helicopter with a Geometrics G-822A Cesium magnetometer and a ProspecTEM EM system featuring a 5.6-metre transmitter loop sending 2.75-ms pulses at 30 Hz.
