Notes

1. Intervals are down-hole lengths. Estimated true widths range from 60% to 100% of reported intervals. Grades are uncut.

2. Included intervals fall within the preceding overall interval and do not necessarily represent its entire length.

3. **AuEq (g/t) = [(Au × 0.95) + (Ag × 0.020 × 0.92) + (Cu × 1.20 × 0.85)] ÷ 0.95, where Au and Ag are expressed in g/t, and Cu in percent.

4. The calculation uses metal prices of US$3,000/oz gold, US$60/oz silver and US$5.25/lb copper with assumed recoveries of 95%, 92%, and 85% respectively. Copper is included in AuEq where the intercept's copper grade is 0.04% or higher. A hyphen (-) in the copper column indicates a grade below 0.04%.

5. Recovery assumptions are based on metallurgical results announced on August 25, 2026, and used in the maiden Mineral Resource announced on September 8, 2026.
