Northisle Provides Update on Largest Ever Field Program at North Island

Northisle Copper and Gold Inc. has announced a significantly expanded field program for its North Island Project in British Columbia, representing the largest exploration effort in the company's history. The program has been increased by more than 20,000 metres compared to initial plans, bringing the total 2025 drilling target to 27,000 metres. The comprehensive initiative encompasses drilling, field exploration, environmental data collection, and geotechnical site investigation activities.

The expanded program is strategically designed to support completion of a pre-feasibility study for the North Island Project by the end of 2026, marking a critical milestone in the project's development timeline. Beyond the immediate drilling objectives, the field exploration program is intended to advance the company's property-wide exploration thesis across what management describes as a 35-kilometre porphyry district.

Following the completion of financing in August 2025, Northisle has implemented significant operational improvements including site upgrades and expanded field teams to support the ambitious exploration schedule. The company's leadership emphasizes their commitment to rapid development while maintaining collaborative relationships with First Nations, provincial, and federal stakeholders.

This substantial increase in drilling activity reflects Northisle's confidence in the North Island Project's potential and positions the company for accelerated resource definition and project advancement. The comprehensive approach combining technical work with environmental and geotechnical studies demonstrates a methodical progression toward potential development decisions, while the expanded scope suggests management sees significant value creation opportunity in the broader porphyry system.
