Northisle Copper and Gold Inc. announced that the Company has commenced a Phase 3 drill program at Northwest Expo, focused on the Zone 1 gold-enriched target. The Company has completed a total of 19 drill holes totaling 8,491 metres across the Northwest Expo, Goodspeed and Pemberton Hills targets prior to the addition of the Phase 3 program. Of these holes, 5 assays have now been released, with a further 14 holes pending.

The additional drilling at Northwest Expo is targeted at in-filling the area around the higher-grade breccia identified by NW23-13 and further scout drilling to the southeast of Zone 1 intended to vector towards a potential porphyry source identified by alteration mapping, soil/silt geochemistry and geophysics. The first drill hole in Phase 3 at Northwest Expo has already been completed and is now being logged on a priority basis. In addition to the above drill program, a ground magnetic survey will be carried out over the area southeast of Zone 1 described above.

The goal of this survey is to further aid vectoring towards a potential porphyry sources of the lithocap hosted mineralization at Northwest Expo Zone 1. A second magnetic survey will be carried out at Goodspeed south of the 2022 induced polarization /magnetic survey area which showed a large magnetic anomaly which was open to the south. This anomaly was targeted with two drill holes during 2023. Assays for these holes are pending.

Both magnetic surveys are scheduled to be completed during October 2023.
