Northisle Announces Near Surface Intercepts and Higher-Grade Intercepts at Depth at West Goodspeed on its North Island Project

Vancouver, B.C. – Northisle Copper and Gold Inc. (TSX-V: NCX, OTCQX: NTCPF) (“Northisle” or the “Company”) is pleased to announce initial results from its 2025 exploration campaign, with four drill holes at the West Goodspeed target and the successful mobilization of a Scan by Veracio mobile XRF scanning system to the North Island Project. The results, and the addition of the scanning system, represent key steps in Northisle’s 2025 exploration strategy, focused on increasing higher-margin resources in the Northwest Corridor and accelerating target generation across the 35-kilometre North Island Project porphyry belt. Sam Lee, President and CEO stated “Drilling at West Goodspeed continues to reinforce the potential for near-surface deposits in the Northwest Corridor. We are encouraged by the continuity of mineralization, including in the higher-grade zones at depth. The intercepts observed in multiple holes underscore the strength of the system outlined at West Goodspeed during the 2023 and 2024 campaigns and the growing understanding of the mineralized system in this area.”
