Cartier Resources begins met testwork at Cadillac

Executive Summary

• Cartier Resources Inc. has initiated a metallurgical testwork program on samples from the Main sector of its Cadillac project in Quebec, supervised by Soutex.
• The company announced a comprehensive 2025-2027 exploration roadmap, including a 100,000-metre drilling program and environmental baseline studies for the Chimo mine tailings.
• Metallurgical results are expected in the first quarter of 2026, aiming to define gold recovery rates and support future project development.

Key Details

• Metallurgical Testwork Program:

  • Supervisor: Soutex (Quebec City).
  • Sample Source: 388.7 kilograms of representative NZ-size half-drill core samples from the Main sector (Chimo, East Chimo, and West Nordeau deposits).
  • Sample Composition:
    • Chimo deposit: 126.1 kg (composites 1 and 2).
    • East Chimo deposit: 132.6 kg (composites 3 and 4).
    • West Nordeau deposit: 130.0 kg (composites 5 and 6).
  • Sample Origin: 92% of samples are from holes drilled by Cartier between 2017 and 2023.
  • Processing Method: Samples shipped to ALS Canada Ltd. (Kamloops, B.C.) for cyanidation tests at three different grind sizes, followed by gravimetric concentration separation and cyanide destruction tests of gravity tails.
  • Additional Testing: Comminution tests, chemical characterization, and mineralogical characterization to define grindability and predict process behavior.
  • Key Objectives:
    • Define expected gold recovery rates and improve upon historical results from the Chimo deposit.
    • Establish first-time metallurgical recovery data for East Chimo and West Nordeau satellite deposits.
    • Support the development of an integrated process flow sheet.
    • Provide critical data for future trade-off studies.
  • Timeline: Results expected in the first quarter of 2026.

• 2025-2027 Exploration Program Milestones:

  • Drilling Program:
    • Scope: 100,000-metre drilling program comprising 600 holes.
    • Timeline: Third quarter 2025 to second quarter 2027.
    • Objective: Expand known gold zones and test new shallow-surface high-potential targets along the 15-kilometre Cadillac fault zone.
    • Context: Recent consolidation of landholding allows for unrestricted exploration for the first time in over 90 years.
  • Environmental and Economic Studies:
    • Timeline: Third quarter 2025 to third quarter 2026.
    • Components:
      1. Environmental baseline desktop study.
      2. Preliminary environmental geochemical characterization.
    • Tailings Assessment: Initial assessment of the economic potential of past-producing Chimo mine tailings to determine if gold can be extracted economically.

• Project Background & Resources (Cadillac Project):

  • Location: Val d'Or mining camp, Quebec.
  • Land Package: 14,000 hectares along a 15-kilometre stretch of the Cadillac fault.
  • Preliminary Economic Assessment (PEA) Highlights:
    • Based on a gold price of $1,750 USD/oz.
    • Demonstrated economic viability for a two-kilometre segment.
    • Projected average annual production: 116,900 oz.
    • Mine life: 9.7 years.
  • Resource Estimates (NI 43-101 Technical Report, effective May 29, 2023):
    • Indicated Resources: 720,000 ounces (7.1 million tonnes at 3.1 g/t Au).
    • Inferred Resources: 1,633,000 ounces (18.5 million tonnes at 2.8 g/t Au).
