Greenstone mine highlights and expansion potential

• Greenstone is positioned as one of Canada’s largest and highest-grade open-pit gold mines, with a 15+ year initial mine life and average grade of 1.23 g/t.

• Expected to produce ~390,000 oz/year for the first five years, with significant underground and open-pit expansion potential.

• Consolidation of 100% ownership adds 2.3 Moz reserves and increases annual production by 160,000 oz for the first five years.

• Ramp-up progress shows >60% throughput achieved in August, with mining fleet operating to plan.

• Near-mine and belt-scale exploration targets offer further resource upside.
