NorthWest Copper Reports High-Grade Results from Kwanika Drill

NorthWest Copper Corp. has announced promising results from its second drill hole in the 2025 diamond drilling program at the Kwanika project. The hole, designated K-25-272, intersected multiple mineralized intervals, including a significant 16.9 metres grading 1.37% copper equivalent (CuEq). This outcome marks an extension of high-grade mineralization down dip by 50 metres and reinforces the potential for further expansion at depth.

The K-25-272 hole, part of a planned 5,135 metre drilling campaign consisting of 17 holes, was drilled to a total depth of 456 metres. The results follow closely on the heels of the first drill hole, which reported 44 metres grading 3.18% CuEq on October 6, 2025. Together, these findings bolster confidence in the higher-grade target model that NorthWest announced on April 10, 2025.

Significant Drill Hole Highlights

The K-25-272 drill hole yielded several noteworthy results across different zones. In the Open Pit Zone, it returned 28.0 metres of 0.58% Cu and 0.16 g/t Au, translating to 0.73% CuEq from a depth of 50.0 metres. In the Central Zone, it reported 20.3 metres of 0.66% Cu and 0.48 g/t Au (equating to 1.12% CuEq) from 332.3 metres, alongside the previously mentioned 16.9 metres of 0.55% Cu and 0.88 g/t Au from 385.3 metres.

In the Western Zone, a separate interval revealed 22.0 metres of 0.41% Cu and 0.72 g/t Au, corresponding to 1.07% CuEq from a depth of 442.0 metres.

Paul Olmsted, CEO of NorthWest, expressed enthusiasm about the results, stating that they reinforce the company’s strategy focusing on high-grade targets. He noted, “This second hole builds on the excellent results from our first hole, which returned 44 metres grading 3.18% CuEq.” He emphasized the strong copper and gold grades, as well as the confirmation of down-dip extensions, which support the project’s economic viability as outlined in the 2023 Preliminary Economic Assessment (PEA).

Continuing Exploration Efforts at Kwanika

NorthWest’s Kwanika project is central to its exploration strategy, with the current drilling program aimed at updating the mineral resource estimate and refining mine design for both open pit and underground mining. The focus is on delineating higher-grade copper-gold zones, which could significantly improve project economics compared to previous assessments.

The Kwanika deposit is divided into three interconnected zones: the Pit Zone, Central Zone, and Western Zone. The latest drill campaign is designed to enhance the understanding of these mineralized structures and their geometry, addressing challenges from prior drilling that was often conducted at low angles.

In terms of drilling methodology, the K-25-272 hole utilized HQ (63.5 mm) core samples, which were analyzed for both copper and gold content. The assay process involved rigorous quality control measures, with samples dispatched to Activation Laboratories Ltd. in Kamloops, British Columbia. The laboratory’s protocols comply with ISO 17025 standards for quality assurance.

Geoff Chinn, NorthWest’s Vice President of Business Development and Exploration, remarked on the implications of the findings: “Our second hole continues to perform exceptionally well against our high-grade Target Model.” He noted the importance of the results in understanding the structural controls on mineralization and their implications for future resource updates.

As NorthWest Copper advances its drilling initiatives, the emphasis remains on unlocking value for shareholders by confirming and expanding the high-grade resource potential at Kwanika. The results from the ongoing program are expected to play a vital role in shaping the project’s future development.
