Northisle Copper and Gold Inc. announced the first batch of drill results from its 2023 Phase 3 program at Northwest Expo which demonstrate continuity of the gold rich Zone 1 in Northwest Expo. The Company has a number of important catalysts over the next several months which it believes will continue to establish the North Island Project as one of the best new mining camps in the world. Phase 3 of the 2023 Northwest Expo drilling program is comprised of eight drill holes.

Technical Report on the Island Copper Property Logging, Sampling and Assaying Procedures and QA/QC The diamond drill core logging and sampling program was carried out under a rigorous quality assurance /quality control program using industry best practices.

Drill intersections in this release are typically HQ to 100 m and NQ thereafter to the end of holes. Half-core was sent for assays reported in this news release. Prior to cutting core for assay bulk density was also determined on site by taking 15 to 20 cm lengths of whole core of each lithology at 10 m intervals.

Standards and blanks in 2023 drill results to date have been approved as acceptable. Duplicate data add to the long-term estimates of precision for assay data on the project and precision for drill results reported is deemed to be within acceptable levels.
