FOCUS GRAPHITE ANNOUNCES SEDAR+ FILING OF THE NI 43-101 TECHNICAL REPORT WITH THE UPDATED MINERAL RESOURCE FOR THE LAC TETEPISCA PROJECT

Focus Graphite Inc. has filed the report on SEDAR+ for the upgraded mineral resource estimate (MRE) on its 100-per-cent-owned Lac Tetepisca project in Quebec. The project lies within the Nitassinan (ancestral land) of the Pessamit Innu First Nation of Betsiamites, Quebec. The MRE was completed pursuant to the requirements of National Instrument 43-101, Standards of Disclosure for Mineral Projects.

Highlights:

• One of the largest identified graphite deposits globally: this new mineral resource estimate includes 120.2 million tonnes of indicated resource at 10.27 per cent graphitic carbon (Cg) and 24.1 million tonnes of inferred resource at 9.88 per cent Cg, containing an estimated 14.7 million tonnes of in situ graphite (see table below for additional details regarding the calculation of the MRE and the average Cg grades for the inferred mineral resources and indicated mineral resources);
• High-grade mineral resources: Estimates were calculated based on a conservative cut-off grade of 3.5 per cent Cg and average selling price of $1,200 (U.S.) per tonne for the flake concentrate;
• Significant expansion potential through stepout and infill drilling to extend the deposit to the southwest and at greater depths, plus drill testing of numerous other geophysical anomalies;
• Novel, low-cost AI (artificial intelligence) enabled in situ graphite flake characterization technology expected to be incorporated into a future MOGC (Manicouagan-Ouest graphitic corridor) mineral resource update'
• Acid-generation-mitigation materials from the dolomitic marbles hangingwall are included in the resource shell; they could be used to mitigate acid generation from the tailings storage facility; their acid-buffering capacity is to be published in the coming months;
• There are no material changes in the updated report from the results disclosed on the company's May 7, 2026, press release.

IOS Geosciences Inc., a leading Quebec-based geological consulting firm, was retained to produce a mineral resource estimate update and prepare a technical report. The technical report is available on the company's website and on the company's SEDAR+ profile.

The MRE update was completed by IOS, using results from 150 drill holes totalling 26,095 metres and including 2022 campaign results recently reported and totalling 9,628 metres from 44 drill holes.

The MRE update for the project is based on 150 inclined and subvertical diamond drill holes performed between 2014 and 2022 on the Manicouagan-Ouest graphitic corridor (MOGC) and Southwest MOGC (SW-MOGC) graphite prospect, totalling of 26,095 metres. Focus discovered the MOGC prospect in July, 2012, while conducting reconnaissance geological mapping, prospecting and trenching on the property. The MOGC is defined by a two-kilometre linear magnetic (mag) and electromagnetic (EM) anomaly that trends N035 degrees. Drilling was conducted on a 1.5-kilometre-long segment of the MOGC following 300-metre-long drilling lines oriented N305 degrees and spaced 100 metres, 50 metres or 25 metres apart.

"This updated resource estimate represents a major milestone for Focus Graphite and further validates Lac Tetepisca as one of the largest identified graphite deposits globally," said Dean Hanisch, chief executive officer of Focus Graphite. "With approximately 14.7 million tonnes of contained in situ graphite, the project combines exceptional scale with a high-grade resource profile and remains open for expansion both along strike and at depth. The current resource is based on only a portion of the broader mineralized system, highlighting the significant opportunity for future growth through additional exploration and resource definition.

"With this important resource update now complete, our focus will shift toward advancing metallurgical optimization, process flow sheet development and engineering studies designed to further unlock and quantify the value of the project. We believe these initiatives will help position Lac Tetepisca for advancement toward a preliminary economic assessment over the coming year and further demonstrate its potential to become a strategically important source of graphite supply for North America and its allies."

Next steps

With the updated MRE now complete, Focus intends to advance the next phase of technical development at Lac Tetepisca, including metallurgical optimization, process flow sheet development and engineering studies. These initiatives are expected to support advancement toward a preliminary economic assessment (PEA) and help quantify the economic potential of one of the largest identified graphite deposits globally. Together with the company's Lac Knife project and downstream technology initiatives, Lac Tetepisca forms a key component of Focus's strategy to build an integrated Canadian graphite and advanced materials platform serving North American and allied supply chains.
