Updated Lac Tetepisca Mineral Resource Estimate Highlights Significant Scale and Grade with 120,163 kt Indicated at 10.27% Cg and 24,143 kt Inferred at 9.88% Cg

Ottawa, Ontario - Newsfile Corp. - May 7, 2026 - Focus Graphite Inc. (TSXV: FMS) (OTCQB: FCSMF) (FSE: FKC0) ("Focus" or the "Company"), a Canadian developer of high-grade flake graphite deposits and advanced graphite materials for battery, defence, and industrial applications, is pleased to announce its upgraded mineral resource estimate ("MRE") on its 100%-owned Lac Tetepisca Project (the "Project") in Quebec. The MRE was completed pursuant to the requirements of National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"). Highlights

• One of the Largest Identified Graphite Deposits Globally: This new mineral resource estimate includes 120,163 ktonnes of Indicated Mineral Resources at 10.27% Cg and 24,143 ktonnes of Inferred Mineral Resources at 9.88% Cg (see table below for additional details regarding the calculation of the MRE and the average Cg grades for the Indicated and Inferred Mineral Resources).
• High-Grade Mineral Resources: Estimates were calculated using a conservative 3.5% Cg cut-off grade and a US$1,200 per tonne average selling price for graphite concentrate.
• Significant Expansion Potential: Opportunities exist through step-out and infill drilling to extend the deposit to the southwest and at greater depths, as well as through drill testing of numerous additional geophysical anomalies.
• AI-Enabled Characterization Technology: Novel, low-cost AI-enabled in situ graphite flake characterization technology is expected to be incorporated into a future MOGC mineral resource update.
• Potential Acid generation Mitigation Materials: Dolomitic marble from the hanging wall has been included within the resource shell and may be used to mitigate acid generation within the tailings storage facility. Acid buffering capacity results are expected to be published in the coming months.

IOS Geosciences Inc. ("IOS"), a leading Quebec-based geological consulting firm was retained to produce a mineral resource estimate update and prepare a technical report (the "Technical Report"). The Technical Report will contain the full results of the Company's drill program and a mineral resource estimation update. Pursuant to NI 43-101, the Company will file the Technical Report within forty-five (45) days of the date hereof on the Company's SEDAR+ profile at http://www.sedarplus.ca. 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 sub-vertical diamond drill holes performed between 2014 and 2022 on the Manicouagan-Ouest Graphitic Corridor ("MOGC") and South-West 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 2 kilometre linear Magnetic (MAG) and Electromagnetic (EM) anomaly that trends N035°. Drilling was conducted on a 1.5 km long segment of the MOGC following 300 m long drilling lines oriented N305° and spaced 100 m, 50 m, or 25 m apart.

1. These mineral resources are not mineral reserves as they do not have demonstrated economic viability. The MRE follows current CIM Definition Standards (2014) and CIM MRMR Best Practice Guidelines (2019). A technical report supporting the MRE will be filed within 45 days in accordance with NI 43-101. The results are presented undiluted and are considered to have reasonable prospects for eventual economic extraction ("RPEEE").
2. The independent and qualified persons ("QPs") for the mineral resource estimate, as defined in NI 43-101, are Jean-Michel Dubé, P.Geo. from IOS Geosciences and Alexandre Burelle, P.Eng., from Evomine Consulting. The effective date is April 30th, 2026.
3. The estimate includes four (5) variably mineralized domains and one (1) dilution envelope modeled using LeapFrog Geo and interpolated using LeapFrog Edge.
4. 2.0 m composites were calculated within the mineralized zones using the grade of the adjacent material when assayed or a value of zero when...
