Cartier Resources begins Cadillac environmental studies

Executive Summary

• Cartier Resources awarded Stantec a contract to commence the initial environmental baseline studies for the Cadillac project and an economic assessment of historic Chimo mine tailings.
• The work is split into three parts: (1) desktop environmental baseline study, (2) preliminary geochemical characterization, and (3) feasibility assessment of tailings re‑processing.
• The studies will support planning for a 100,000 m drilling campaign and inform updates to the Preliminary Economic Assessment (PEA).

Key Details

• Contract Award: Stantec, a global sustainable design and engineering firm, selected to perform baseline environmental work and tailings economic assessment.
• Part 1 – Desktop Study: Reviews atmospheric conditions, surface/groundwater, wetlands, fauna, and land use to identify constraints and guide future field work; will feed into Chapter 20 of a potential PEA update.
• Part 2 – Geochemical Characterization: Static tests on ~50 representative lithology samples to evaluate acid generation and metal leaching per GCRMM criteria and MELCCFP Directive 019.
• Part 3 – Tailings Economic Assessment: Systematic sampling of ~550 sites across the Chimo tailings facility to determine feasibility of economic recovery; all required permits will be secured before fieldwork.
• Exploration Context: Studies run concurrently with a planned 100,000‑metre drilling program targeting extensions of known gold zones and new AI‑identified high‑priority targets (collaboration with VRIFY).
• Qualified Person: Ronan Deroff, PGeo, MSc, Vice‑President of Exploration, reviewed and approved the technical content per NI 43‑101.
• Project Scale: Cadillac covers 14,000 ha along a 15‑km fault zone; indicated resources ~720,000 oz Au (7.1 Mt @ 3.1 g/t) and inferred resources ~1.63 M oz Au (18.5 Mt @ 2.8 g/t).
• Economic Context: Preliminary Economic Assessment (using $1,750/oz Au) projects average annual production of 116,900 oz over a 9.7‑year mine life for the initial 2‑km segment; full 15‑km drill program aims to expand this potential.
