NorthWest Experiences Outcomes from Two Holes at Its Kwanika Property Highlighted by 26 Metres of 0.72% Copper and 1.30 g/t Gold from 268 Metres

Northwest Copper Corp. (“NorthWest” or the “Firm”) (TSX-V: NWST) is happy to announce further optimistic drill outcomes from two holes from its 2025 program on the Firm’s 100% owned Kwanika venture in British Columbia. Drill gap Okay-25-281 delivered a superb outcome highlighted by an intercept of 26 metres grading 0.72% Cu, 1.30 gt Au (1.91% copper equal 1 “CuEq”) confirming the Firm’s understanding and expectations of higher-grade zones inside the Kwanika Central Zone. Each drill holes additionally delivered broad intervals of near-surface copper-gold mineralization, strengthening the Firm’s confidence within the preliminary part of the venture’s open pit potential.

The 2 drill holes achieved a number of key aims together with:

• Okay-25-281 prolonged the higher Central Zone by 30 metres to the northeast, in an space that’s considerably wider than anticipated, with the Central Zone remaining open to the northeast,
• Okay-25-281 confirmed the presence of higher-grade mineralization within the decrease Central Zone over substantial thicknesses,
• Elevated understanding of a possible hyperlink between the Central Zone and Pit Zone, and
• Improved confidence within the continuity of near-surface mineralization over vital widths.

By efficiently attaining these aims, the outcomes underscore the potential to outline and develop on the dimensions of higher-grade mineralization inside the Central Zone. This helps the Firm’s technique of specializing in high-grade domains inside the present mineral useful resource to reinforce the economics of a future Preliminary Financial Evaluation (“PEA”). In parallel, the constant near-surface mineralization encountered within the Pit Zone reinforces the chance for a high-grade starter pit, which may present a powerful basis for additional enhancements within the economics of a future PEA.

Paul Olmsted, CEO of NorthWest said: “In 2025, the Firm modified its technique to prioritize higher-grade zones inside the present mineralization at Kwanika. Outcomes from the primary seven holes of the 2025 exploration program have largely met or exceeded expectations, reinforcing the potential for significant grade enhancements by specializing in higher-grade domains. This system to outline these higher-grade zones is progressing exceptionally effectively, metallurgical take a look at work is advancing quickly, and we anticipate saying preliminary outcomes earlier than the tip of the 12 months. This data can be used to assist an up to date mineral useful resource estimate, which can kind the idea for evaluating various top-down underground mining strategies. Our goal is evident: to ship a extra capital-efficient and economically sturdy open pit and underground growth plan in an up to date PEA in comparison with the 2023 PEA ² .”

Geoff Chinn, VP Enterprise Growth and Exploration of NorthWest added: “It’s encouraging to see each holes intersect higher-grade, near-surface mineralization over vital widths, effectively suited to assist a possible starter pit. As well as, a beforehand unmodelled higher-grade copper zone is rising instantly south of Pit Zone 5, probably bettering on our understanding of mineralization inside the broader Pit Zone. Gap Okay-25-281 helps our interpretation of two vast, steady higher-grade mineralized intervals within the Central Zone grading between 1.5% and a pair of.5% CuEq over mixed true thicknesses between 30 and 45 metres separated by late dykes. This gap additionally intersected a large higher Central Zone interval that extends the zone by no less than 30 meters in the direction of the northeast. We additionally observe a transparent development of accelerating gold-to-copper ratios from east to west within the Central Zone, with the Pit Zone exhibiting the same sample, though rotated from south to north. This development suggests a possible hyperlink between the 2 zones, and we anticipate that further drill leads to the approaching weeks ought to assist make clear this relationship.”

Kwanika Exploration Program

On April 10, 2025, NorthWest introduced a refined mannequin for its flagship Kwanika venture (“Goal Mannequin”), highlighting three key higher-grade zones: the Pit, Central and Western Zones. These zones goal grades of 1.5% to 2.5% CuEq over mixed true thicknesses of 30 to 45 metres, to be assessed towards a extra selective top-down bulk underground mining methodology.

The 2025 exploration program is designed to substantiate, outline and develop on the Firm’s understanding of higher-grade copper-gold mineralization inside the present mineral useful resource, with the goal of supporting various bulk mining strategies. Early outcomes from the primary seven holes, together with gap Okay-25-281 and Okay-25-282, verify vital progress towards these aims.

Gap areas for this system are introduced in Determine 1 beneath. Determine 2 illustrates a cross part of the place of holes Okay-25-281 and Okay-25-281 relative to the Goal Mannequin Central and Pit Zones. Steady mineralized intercepts and collar areas are summarized in Desk 1 and Desk 2.

A abstract of the geological elements of the opening is introduced beneath.

Gap Okay-25-281: The opening was drilled with HQ core measurement and sampled on roughly 2-metre intervals from sawn half core materials. The opening was drilled on 265° azimuth with a -70° dip to a depth of 354 metres. The first goal of the opening was to check northeast extensions of the Central Zone in an space poorly outlined by historic low-angle holes.

Earlier than getting into the Central Zone, the opening intersected two near-surface zones inside the Pit Zone. The primary interval was a 38 metre (24 metre true width) consisting of finely disseminated sulphides in potassic-altered (“monzonite”), correlating with Pit Zone 8 starting at 44 metres. The second interval, beginning at 150 metres, returned 26 metres (true width unknown) of upper grades with an growing gold-to copper ratio. This interval consisted of magnetite-hematite alteration inside fine-grained porphyritic diorite with disseminated pyrite. The interval additionally correlates with Pit Zone 8.

At 254 metres, the opening intersected a broad higher Central Zone (Zone 4) interval over 40 metres (33 metre true width) of monzonite reduce by dismembered quartz stockwork. This interval was considerably wider than anticipated and extends the higher Central Zone roughly 30 meters to the northeast, the place it stays open.

Additional down the opening mineralization is terminated by late dykes, then resumes on the alternative aspect in extremely tectonized potassic alteration crosscut by dismembered quartz stockwork over 24 metres (20 metre true width). This interval correlates with the decrease Central Zone (Zone 6) and equally extends the zone 30 metres towards the northeast, the place it additionally stays open.

In abstract, gap Okay-25-281 was profitable in extending the Central Zone by roughly 30 metres towards the northeast.

Gap Okay-25-282: The opening was drilled utilizing HQ core measurement sampled on roughly 2-metre intervals from sawn half core. The opening was drilled on 140° azimuth with a -75° dip to a depth of 401 metres. The first goal of the opening was to check the closure (intersection) of Central Zone (Zone 4) and the Western Zone (Zone 2).

At 22 metres, the opening intersected a broad interval of high-grade, copper-dominant mineralization over 76 metres (54 metre true width) hosted in monzonite crosscut by quartz stockwork. This intersection helps to outline the grade, geometry and orientation of a definite high-grade copper zone instantly south of Pit Zone 5. Steel zonation on this space additionally exhibits a rotation, with excessive copper-to-gold ratios transitioning to excessive gold-to-copper ratios in the direction of the north. This shift in steel zonation from east-west within the Central Zone to south-north within the Pit Zone offers further assist that these zones are associated.

In abstract, gap Okay-25-282 efficiently confirmed the presence of a separate, copper-dominant high-grade mineralized zone inside the Pit Zone which will prolong towards the Central Zone. This potential connection can be examined with outcomes from holes Okay-25-273 and Okay-25-287. In any other case, the opening was drilled too far to the east to have examined the intersection between the Central and the Western Zones.
