CARTIER ANNOUNCES FILING OF UPDATED MINERAL RESOURCE ESTIMATE TECHNICAL REPORT FOR THE CADILLAC PROJECT

Cartier Resources Inc. has filed the National Instrument 43-101-compliant updated mineral resource estimate (MRE) technical report on its 100-per-cent-owned flagship Cadillac project, located in Val d’Or (Abitibi), Que. Report results were previously announced in Cartier’s news release dated Dec. 18, 2025. The updated estimate includes approximately 110,000 metres of drilling completed by Cartier from 2016 to 2024, as well as 420,000 metres drilling completed by previous mining companies.

The MRE was independently prepared by PLR Resources Inc. and Evomine, specialists in mineral resource estimates and project evaluations, in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects, with an effective date of Nov. 11, 2025.

The full report, entitled “NI 43-101 Technical Report and Mineral Resource Estimate on the Cadillac Project, Val-d’Or, Abitibi, Quebec, Canada,” can be found on the company’s website and on SEDAR+.

Strategic and investment significance highlights of the updated mineral resource estimate:

Growing gold resource: Compared with the 2023 preliminary economic assessment (PEA), total gold resources now contain 9,953,000 tonnes at a grade of 2.40 grams per tonne (g/t) gold (Au) for 767,800 ounces measured and indicated (M&I) (a 7-per-cent increase) and 35,185,000 tonnes at a grade of 2.14 g/t Au for 2,416,900 ounces inferred (a 48-per-cent increase), following the first-ever consolidation (2022) of all gold sectors across the entire Cadillac project.
Increasing confidence and derisking: M&I resources represent 25 per cent of total resources, including 5,988,000 tonnes at a grade of 2.61 g/t au for 502,600 ounces measured, strengthening the project’s development profile.
Flexible development pathways: Twelve per cent of total gold resources are pit-constrained, offering near-term optionality with 3.5 million tonnes at a grade of 1.84 g/t Au for 207,800 ounces M&I and 4.74 million tonnes at a grade of 1.13 g/t Au for 172,600 ounces inferred.
Large underground resource and existing infrastructure advantages: Over 88 per cent of total gold resources are underground — constrained with 6.45 million tonnes at a grade of 2.70 g/t Au for 559,900 ounces M&I and 30.45 million tonnes at a grade of 2.29 g/t Au for 2,244,200 ounces inferred. This large resource is supported by valuable historical infrastructure, including a 920-metre shaft, 500-metre ramp and seven kilometres of drifts; these could significantly reduce future capital requirements and allow management to adapt development strategies.
Camp-scale upside potential: Gold sectors extend over nine kilometres along the Cadillac and Heva fault zones, covering 66 per cent of a 15-kilometre highly prospective gold corridor, leaving six kilometres of strike with strong upside potential to be fully explored for resource expansion.
High-quality core sector: The main sector (Chimo, East Chimo and West Nordeau deposits) hosts 87 per cent of total resources within a three-kilometre mineralized trend and remains open at depth and along strike, providing strong leverage to further drilling success.
Significant exploration target: A conceptual exploration target of eight million to 12 million tonnes of mineralization grading between 2.2 and 2.8 g/t Au, representing 600,000 to 1.1 million ounces of gold, highlights the project’s potential to materially grow beyond the current resource base.
