Cygnus Metals (CY5) BMO Global Metals Conference and PDAC Corporate Presentation summary

Project overview and resource highlights

• Chibougamau Copper-Gold Project in Quebec features high-grade resources and near-term development potential in a top-tier mining jurisdiction.

• Measured & Indicated resources total 6.4Mt at 3.0% CuEq, with Inferred resources of 8.5Mt at 3.5% CuEq, among the highest grades on the ASX.

• Resource growth of 29% in contained metal and 98% increase in gold resource over nine months.

• Five deposits operate under a hub-and-spoke model, supported by a 900ktpa processing facility and established infrastructure.

• Project benefits from government support, fast-tracked studies, and a mining-friendly community.

Exploration, drilling, and growth opportunities

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

• Significant high-grade intersections reported, including 5.9m @ 34.1g/t AuEq and 47.4m @ 7.2% CuEq.

• Golden Eye deposit initial resource: Indicated 91koz @ 5.6g/t AuEq, Inferred 182koz @ 4.6g/t AuEq, with mineralization open and at shallow depth.

• Corner Bay is the flagship, now a +10Mt standalone deposit, making up 69% of the resource.

• Cedar Bay drilling continues to expand resources, with intersections outside current resource boundaries.

Infrastructure, processing, and community engagement

• 900ktpa processing facility and tailings storage facility in place, with a replacement value over C$150M.

• Excellent copper recoveries (up to 98.2%) and concentrate grades (up to 29.6%) achieved.

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

• Strong community relationships, especially with Ouje-Bougoumou First Nation, and ongoing environmental baseline studies.

• Only base metals processing infrastructure within 250km, providing regional consolidation opportunities.
