Northwest Copper starts drilling at Kwanika project

Executive Summary

• Northwest Copper Corp. has mobilized two drill rigs to commence a 5,135‑metre drilling program at its wholly‑owned Kwanika project for the 2025 season.
• The program targets the existing Kwanika Central deposit and two new exploration targets (Transfer and Andesite Breccia) to expand higher‑grade zones, support an updated mineral resource estimate, and inform a revised mine design.
• Drilling is scheduled through the end of October, with 4,285 m allocated to Kwanika Central (14 holes) and 850 m to the Transfer and Andesite Breccia targets (3 holes).

Key Details

• Financing Enablement: Flow‑through financing completed earlier in the year provided capital to mobilize two drill rigs.
• Kwanika Central Deposit: Aim to confirm and expand a higher‑grade target model announced on April 10, 2025; depth goal ≈ 350 m to support updated resource estimate and revised pit/underground bulk mining design.
• Transfer Target: Located ~300 m south of Kwanika Central; near‑surface IP chargeability with favorable alteration and anomalous gold values; drilling will assess alteration orientation, vein intensity, and potential parallel zones to the central deposit.
• Andesite Breccia Target: Situated ~600 m north of Kwanika Central; historic intercept of 87.0 m @ 0.38 % Cu and 0.06 g/t Au from 102.4 m depth in an andesite‑hosted breccia; 350 m planned in one hole to evaluate extension and structural context.
• Drill Program Allocation: Total 5,135 m – 4,285 m (14 holes) at Kwanika Central; 850 m (3 holes) split between Transfer and Andesite Breccia targets.
• Schedule: Drilling to continue through the end of October 2025, with interim updates as results become available.
• Technical Review: Release reviewed and approved by Geoff Chinn, P.Geo., VP Business Development & Exploration, qualified under NI 43‑101.

Notable Quotes

“We are thrilled to launch the next drill program at Kwanika guided by our higher‑grade target model informed by all historical drilling… The 2025 program, together with the 2022 drilling will be used to inform an updated mineral resource including enhanced higher‑grade estimation domains that will be used to support an updated PEA in the first half of 2026.” – Geoff Chinn, Vice‑President Business Development & Exploration.
