Kodiak Completes Shallow Infill Drilling at West and South Zones, Initial Resource Estimate Underway

Executive Summary

• Kodiak Copper reports additional drill results from its 2025 summer program at the MPD copper‑gold porphyry project, confirming shallow, higher‑grade mineralization in the West Zone and near‑surface mineralization over ~350 m in the South Zone.
• Intersections include notable grades such as 2.11 g/t Au, 0.21 % Cu over 7 m (AXE‑25‑009) and 0.41 % Cu, 0.15 g/t Au over 21 m (AXE‑25‑006).
• The data will be used to prepare an Initial Mineral Resource Estimate for the West, South and Adit Zones, targeted for Q4 2025; resource work remains on budget and schedule.

Key Details

• Drill Program Scope: 10 holes (1,173 m) at West Zone; 3 holes (232 m) at South Zone.
• West Zone Highlights:
• AXE‑25‑009 – 2.11 g/t Au, 0.21 % Cu, 1.20 g/t Ag over 7 m (84–91 m); broader interval 0.28 g/t Au, 0.14 % Cu, 0.54 g/t Ag over 103 m.
• AXE‑25‑006 – 0.41 % Cu, 0.15 g/t Au, 0.90 g/t Ag over 21 m (81–102 m); larger interval 0.22 % Cu, 0.11 g/t Au, 0.74 g/t Ag over 138 m.
• Additional holes show consistent mineralization; West Zone remains open south, west and at depth, covering ~650 m × 300 m to 960 m depth.
• South Zone Highlights:
• Three new holes in the northeastern extension (formerly Mid Zone) confirm near‑surface mineralization over ~350 m width.
• Potential for eastward expansion of the South Zone indicated.
• Assay Summary Table (selected intervals):
• West Zone overall weighted averages range from 0.08–0.31 % Cu and 0.08–0.29 g/t Au across holes AXE‑25‑001 to AXE‑25‑010.
• South Zone weighted averages include 0.07 % Cu, 0.02 g/t Au (AXE‑25‑011) and 0.34 % Cu, 0.03 g/t Au (AXE‑25‑012).
• Resource Estimate Timeline: All 2025 summer drill results now reported; to be incorporated into an Initial Mineral Resource Estimate expected Q4 2025.
• Budget & Schedule: Resource estimation work remains on budget and on schedule.
• Qualified Person: Dave Skelton, P.Geo., VP Exploration, has approved the technical information per NI 43‑101.

Notable Quotes

“The West Zone keeps delivering attractive drill results… This bodes well for future economics and underscores the West Zone's important role for the full MPD mineral resource estimate expected in the fourth quarter.” – Claudia Tornquist, President & CEO
