Cygnus Metals (CY5) Chibougamau Resource Update presentation summary

Project highlights and resource update

• Chibougamau Copper-Gold Project in Quebec features a hub-and-spoke model with five deposits and a 900ktpa processing facility in place.

• Measured & Indicated resources total 6.4Mt at 3.0% CuEq (193kt CuEq), and Inferred resources are 8.5Mt at 3.5% CuEq (295kt CuEq).

• Resource update shows a 29% increase in contained metal and a 98% increase in gold resource since the previous estimate.

• New Golden Eye deposit adds 274koz AuEq, with high-grade intersections and 29% of its resource in the Indicated category.

• Total contained metals: 331kt copper, 621koz gold, and 3.7Moz silver.

Growth strategy and exploration

• Two drill rigs are active, targeting further resource extensions and brownfield exploration.

• AI-driven data compilation and modern geophysics are being used to identify new targets.

• Landholding expanded by 50% to 282km², with systematic drilling and resource conversion underway.

• Historic production in the district totals 945kt copper and 3.5Moz gold, with significant underexplored areas.

• Multiple high-grade intersections and open targets highlight ongoing growth potential.

Infrastructure and development

• Project benefits from established infrastructure: processing plant, tailings facility, roads, rail, hydropower, and local workforce.

• High copper recoveries (up to 98.2%) and concentrate grades (up to 29.6%) achieved in metallurgical tests.

• C$1.3M funding secured from Canada’s Critical Minerals Infrastructure Fund for pre-construction milestones.

• Environmental baseline studies and feasibility led by Ausenco are in progress.

• Strong community relations, especially with Ouje-Bougoumou First Nation.
