NorthWest Copper hits high-grade intercepts at Kwanika

NorthWest Copper (TSX-V: NWST) reported drill results from hole K-25-287, which they completed as part of its 2025 program at the company’s wholly-owned Kwanika project in British Columbia. The hole returned higher-grade results in both the Pit and Central zones. This included a significant near-surface intercept of 25.9 metres grading 0.91% copper and 1.29g/t gold (2.09% copper equivalent, “CuEq”).

“This drill hole is the 15th reported from our 2025 exploration program at Kwanika, a program which we believe has been highly successful in achieving its goals and will be value accretive," Paul Olmsted, CEO of NorthWest, stated.

He added: "The program exceeded expectations by demonstrating the continuity of higher-grade zones over significant widths in both the Central zone and the Pit zone, materially improving our understanding of the mineralization. Results from the Pit zone, in particular, are expected to support higher-grade open pit mineral resources. When combined with increased confidence in the higher-grade Central zone to support alternative underground mining methods, and targeted recovery improvements from ongoing metallurgical test work, we expect to deliver an exciting mineral resource update in the first quarter of the year.

"Together, these developments are expected to support the potential for a more capital-efficient and economically compelling combined open pit and underground development plan, to be reflected in an updated preliminary economic assessment (PEA) delivered in mid 2026 that will aim to improve upon the 2023 PEA.”

“With the final drill hole reported in the Kwanika Central deposit, we have confirmed that potassic alteration crosscut by mineralized quartz stockwork, later deformed by faults and fractures and overprinted by silica, sericite and pyrite, forms discrete continuous zones of higher-grade mineralization," Geoff Chinn, VP of business development and exploration, added.

The 2025 exploration program aimed to confirm, define, and expand the company’s understanding of higher-grade copper-gold mineralization within the near-surface and underground portions of the current mineral resources. Results from the 15 holes drilled at Kwanika, including holes K-25-287, demonstrate the program's merits and indicate meaningful progress toward these objectives.

NorthWest announced a refined model for its flagship Kwanika project on April 10, 2025, highlighting three key higher-grade zones: the Pit, Central, and Western zones. These zones target grades of 1.5% to 2.5% CuEq over combined true thicknesses of 30 to 45 metres, to be assessed against a more selective top-down bulk underground mining method.
