NorthWest Reports Results From Three Holes at Its Kwanika Property Highlighted by Near Surface Intercept of 58 Metres of 0.96% Copper and 1.04 G/T Gold (1.92% CuEq) From 94 Metres

On December 10, 2025, NorthWest Copper reported additional positive drill results from three holes of its 2025 program at the Kwanika copper-gold project in British Columbia. The results continue to define and expand near-surface, higher-grade zones within the project's Pit Zone.

The highlight was from hole K-25-275, which intersected 58 metres of 0.96% copper and 1.04 g/t gold (1.92% CuEq) starting from a depth of 94 metres. Other significant intercepts included 50.5 metres of 0.92 g/t gold from 29.5 metres in the same hole, and 70 metres of 0.95 g/t gold from 52 metres in hole K-25-284.

Management stated that these results validate the 2025 drill program's objective of improving the understanding of higher-grade mineralization. This work, combined with upcoming metallurgical results, is expected to support a higher-quality mineral resource estimate and a more capital-efficient development plan in an updated Preliminary Economic Assessment (PEA).

The news is materially positive as it successfully continues to execute on the company's stated strategy and de-risks the Kwanika project.

• Strategic Execution: In early 2025, the company shifted its strategy to focus on defining higher-grade zones at Kwanika to improve the economics of the 2023 PEA. After raising approximately $4.6 million in mid-2025, the company commenced a drill program in September. The results since October 6 have been consistently strong, and this latest release is a continuation of that success. It demonstrates management's ability to execute its plan.

• Confirms Geological Model: The results validate the "Higher-Grade Target Model" announced on April 10, 2025. Consistently hitting significant mineralization where predicted increases confidence in the geological interpretation and reduces exploration risk. The definition of multiple, discrete higher-grade zones at shallow depths (Pit Zone 5, Pit Zone 10) is a key step toward delineating a potential starter pit.

• Supports PEA Update: Each successful drill result provides a crucial data point for the planned updated Mineral Resource Estimate (MRE) and subsequent PEA, which are the primary catalysts for the company. The goal is to demonstrate a more robust, lower-capex, staged development plan than the one outlined in the 2023 PEA. These near-surface, high-grade results directly support that objective.

• Market Context: The stock price rallied significantly from September to early October (from ~$0.22 to a high of $0.58) on the back of the initial drill results. The price has since pulled back to the $0.37 level. This news should provide strong support for the share price and reinforces the positive exploration narrative, justifying the market's earlier re-rating. While not a singular game-changing hole, it is part of a series of materially positive results that are fundamentally improving the project's potential.

NorthWest Copper Corp. is a Canadian mineral exploration company focused on advancing its portfolio of copper-gold projects in British Columbia. Its flagship asset is the Kwanika project, a large-scale porphyry copper-gold deposit. The company's current strategy, initiated in early 2025, is to de-risk Kwanika and improve on its 2023 Preliminary Economic Assessment (PEA) by defining higher-grade, near-surface zones that could support a more capital-efficient, staged development plan.
