NorthWest Copper Corp. reports positive assay results from second hole of 2025 drilling program at Kwanika, with 16.9 meters grading 1.37% copper equivalent. Results confirm higher-grade mineralization down dip by 50 meters, validating Target Model for selective underground mining approach. Additional holes show potential for low-cost open pit mining and expansion at depth. CEO and VP express confidence in project’s value and potential for economic improvement.

The Kwanika diamond drilling program aims to support an updated mineral resource estimate and guide a revised mine design, focusing on higher-grade copper-gold zones aligned with the Target Model. Three interconnected zones – Pit Zone, Central Zone, and Western Zone – host mineralized intervals, with drilling designed to validate and expand understanding of higher-grade mineralization. Collar locations and intercepts detailed in recent news release.

Hole K-25-272 drilled towards southwest to validate Target Model in less explored area, intersecting lower grade zones near surface suitable for open pit mining. At greater depth, hole intersected convergence of Central and Western Zones, with multiple mineralized intervals confirming Target Model expectations. Results show potential for further expansion at depth, reinforcing confidence in geological model and future resource updates. In drilling at Kwanika in 2025, Hole K-25-272 partially intersected a parallel mineralized structure, demonstrating attractive near-surface copper-gold mineralization suitable for open pit mining. The hole confirms the Target Model and extends higher-grade mineralization in the Central and Western Zones, remaining open for further expansion. Drill results are detailed in Table 1. Quality assurance and control were carefully managed throughout the drilling process.
