FIRST CANADIAN GRAPHITE ANNOUNCES SIGNIFICANT NEW DISCOVERY AT LAC GUERET SOUTH

First Canadian Graphite Inc. has discovered visible high-grade graphite at surface within zone 13, a previously unexplored kilometre-scale electromagnetic (EM) anomaly at its district-scale Lac Gueret South project in Quebec.

The newly confirmed graphite occurrence represents the first geological confirmation of mineralization within an EM conductor extending approximately 3.8 kilometres in length and up to 625 metres in width, highlighting the potential for a significant new graphite system beyond the company's existing National Instrument 43-101 mineral resource.

Field crews are currently mapping, sampling and tracing graphite-bearing outcrops along strike to determine the extent of the mineralized system while advancing drill target definition.

"This is one of the most exciting exploration developments we've seen on the property," said John LaGourgue, First Canadian Graphite chief executive officer. "Not only have we confirmed visible graphite in a completely new exploration area, but we've done so within one of the largest untested conductors on the property. Combined with the scale of the anomaly and the success of our historical zone 1 resource, we believe zone 13 has the potential to become another major graphite discovery within the Lac Gueret district."

The discovery further demonstrates the exploration potential across First Canadian Graphite's 167-square-kilometre land package, one of the largest graphite claim positions in the Lac Gueret district.

Assay results from current field sampling are expected in the coming weeks and will assist in prioritizing drill targets for the next phase of exploration. Bulk samples will also be delivered to Corem for metallurgy and floatation characteristics testing.

Photographs of the graphite-bearing outcrops and field activities are available on the company's website and social media channels.

Field procedures

A seasoned exploration crew is currently executing a ground electromagnetic survey on zone 13 using Beep Mat TM-8 instrumentation to delineate shallow conductors. Identified targets are being hand excavated to expose graphitic outcrops for sampling.

The crew has successfully traced a continuous conductor over a 3,157-metre strike length, with sampling expanding across true or apparent widths greater than 100 metres. The survey is continuing.

Details on sample point locations and assay results will be provided in a timely manner.

The company has filed an NI 43-101 technical report with a detailed mineral resource estimate for the Lac Gueret South project (formerly known as the Berkwood project), dated June 19, 2019, and completed by independent experts Edward Lyons (Tekhne Resources), Florent Baril (Bumigeme) and Claude Duplessis (Goldminds Geoservices).

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 southwestern 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 (NI 43-101 technical report mineral resource estimate). The property also features several other zones with surface graphite samples, offering strong exploration potential. In early 2026, the company increased its landholdings 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.
