Key Highlights

• Indicated Mineral Resource: 1,640,000 tonnes at 7.00% graphitic carbon, containing 115,000 tonnes of Cg
• Inferred Mineral Resource: 1,580,000 tonnes at 7.00% Cg, containing 111,000 tonnes of Cg
• High-Grade at Surface: Mineralization near surface with minimal overburden provides immediate access and selective mining potential.
• Strategic Location: Mineral Resources located near major transportation routes with claims adjacent to the Lac-des-Iles processing facility.
• Significant Infill Potential: Mineral Resource Estimate demonstrates potential for expansion between and within existing pit shells across all zones.
• Expansion Opportunities: The Lac-Aux-Bouleaux property contains six additional mineralization zones identified from geophysics work for future exploration and potential Mineral Resource expansion.
• Next Phase Development: Bulk sampling program to advance metallurgical testing, surface extraction cost analysis, and permitting studies

Graphano Energy Ltd. (TSX-V: GEL) (FSE: 97G0)  is pleased to announce an initial Mineral Resource estimate for its 100%-owned graphite properties located in the Lac Saguay region in Québec, Canada. The Mineral Resource is reported at 3.00% Cg cut-off within an optimized pit shell and highlights the project’s tonnage and grade across multiple zones.

The Lac Saguay Graphite Project Mineral Resource incorporates the LAB property, including the Pit Zone, Zone 1, and Zone 3, as well as the Standard property, which has been a primary focus of recent exploration efforts.

Luisa Moreno, CEO of Graphano, stated: “These results underscore the potential of both LAB and Standard to become a significant source of high-grade graphite in North America. The project’s resource profile and grade are compelling and support our strategy to advance toward development.”

Next Steps

Graphano plans to execute a comprehensive development program focused on:

• Infill drilling campaign to upgrade Inferred resources to Indicated and Measured categories
• Bulk sampling program to support expanded metallurgical testing
• Economic evaluation of near-surface material extraction costs
• Environmental baseline studies to support permitting processes to fast-track development

Lac Saguay Graphite Project Mineral Resource Estimate — Effective Date: July 15, 2025

Mineral Resource Notes:

1) Mineral Resources were prepared in accordance with the CIM Definition Standards for Mineral Resources and Mineral Reserves (MRMR) (2014) and CIM MRMR Best Practice Guidelines (2019).
2) Graphitic carbon (Cg %) grade was estimated from 1.5m downhole assay composites using Inverse Distance Squared interpolation. No grade capping was applied.
3) LAB model block size is 5 m (x) by 5 m (y) by 6 m (z) with 4 units of sub-blocking and Standard model block size is 4 m (x) by 4 m (y) by 4 m (z) with 4 units of sub-blocking.
4) Bulk density of 2.80 g/cm³ was applied to all mineralized domains.
5) Mineral Resources are defined within an optimized pit shell with an average slope angle of 45⁰ and an overall strip ratio of 4.73:1 (waste: mineralized material)
6) Parameters used in pit optimization include a long-term average graphite flake concentrate market price of $0.99/lb ($USD1,500/t), an overall metallurgical recovery of 90%, and costs at $4.50/t mining, $30/t processing, $12/t G&A, and $22/t transportation. All prices are CDN unless otherwise specified using an exchange rate of 1.35 CDN:USD.
7) Mineral Resources are reported at a cut-off grade of 3.0% Cg with the optimized pit shell and define reasonable prospects for eventual economic extraction by open pit mining methods.
8) Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.
9) Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
10) Mineral Resource tonnages are rounded to the nearest 10,000. Contained Cg is rounded to the nearest 1,000.

Sample Data

The LAB Mineral Resource is based on 49 drill holes for 3,963m completed by Graphano and 86 drill holes for 6,199m completed by previous operators . The Standard Mineral Resource is based on 35 drill holes for 3,164m completed by Graphano. All drill core samples completed by Graphano were sampled, stored, and shipped using industry best practices and were delivered to Activation Laboratories (“Actlabs“) in Ancaster, Ontario for sample preparation and analyses using Actlabs’ Code 4F-C Graphitic, analyzing C-Graphite (infrared) where the sample is subjected to a multistage furnace treatment to remove all forms of carbon except for graphitic carbon; and C-Total (infrared). Actlabs is an independent commercial and ISO Certified Laboratory. The core sample program also included field duplicates, blanks, and a graphite standard sample for quality control and quality assurance purposes.
