Confirmation Of Higher-Grade Zones At Kwanika Property

TORONTO – NorthWest Copper Corp. reported positive drill results from two holes from its 2025 program at the Kwanika project in British Columbia. Drill hole K-25-281 delivered an excellent result highlighted by an intercept of 26 metres grading 0.72% Cu, 1.30 g/t Au (1.91% copper equivalent, “CuEq”) confirming the Company’s understanding and expectations of higher-grade zones within the Kwanika Central Zone. Both drill holes also delivered broad intervals of near-surface copper-gold mineralization, strengthening the Company’s confidence in the initial phase of the project’s open pit potential.
The two drill holes achieved several key objectives including: 1) K-25-281 extended the upper Central Zone by 30 metres to the northeast, in an area that is significantly wider than expected, with the Central Zone remaining open to the northeast. 2) K-25-281 confirmed the presence of higher-grade mineralization in the lower Central Zone over substantial thicknesses.
Increased understanding of a potential link between the Central Zone and Pit Zone, and improved confidence in the continuity of near-surface mineralization over significant widths.
By successfully achieving these objectives, the results underscore the potential to define and expand on the size of higher-grade mineralization within the Central Zone. This supports the Company’s strategy of focusing on high-grade domains within the existing mineral resource to enhance the economics of a future Preliminary Economic Assessment (PEA). In parallel, the consistent near-surface mineralization encountered in the Pit Zone reinforces the opportunity for a high-grade starter pit, which could provide a strong foundation for further improvements in the economics of a future PEA.
