Northisle Announces Continued Growth of West Goodspeed Target to over 1.2km Strike with Additional High-Grade Intervals

Northisle Copper and Gold Inc. has announced significant progress in its 2025 exploration campaign at the North Island Project in British Columbia, with ten additional drill holes successfully expanding the West Goodspeed target to over 1.2 kilometers of strike length. The drilling program has not only increased the footprint of mineralization but has also strengthened the geological interpretation of the mineralized systems in the area, while identifying additional opportunities for future expansion.

The company's strategic approach focuses on systematically building its mineral inventory to support an upcoming pre-feasibility study, with West Goodspeed now being incorporated into this assessment. This represents a significant milestone in advancing the project toward development as the expanded target provides greater confidence in the resource potential and demonstrates the continuity of mineralization across a substantial strike length.

Concurrent with the West Goodspeed expansion, Northisle continues its comprehensive drilling program at the established Northwest Expo and Red Dog deposits, focusing on infill drilling and geotechnical assessment. This dual approach of expanding known targets while advancing existing deposits toward feasibility demonstrates the company's methodical strategy for maximizing the project's potential.

The results highlight the robust exploration potential of the North Island Project and position Northisle well for advancing toward development decisions. The expanded West Goodspeed target, combined with the ongoing work at Northwest Expo and Red Dog, strengthens the overall project profile and supports the company's broader development timeline. As the mining sector continues to seek quality copper-gold projects in stable jurisdictions, Northisle's systematic expansion of its British Columbia asset represents a compelling advancement in Canada's critical minerals development landscape.
