Northisle Copper and Gold Inc. announced that it has received an additional assay result from its 2023 drill program at the Northwest Expo target on the North Island Project. This result represents the grade and thickness result ever drilled on Northwest Expo. Sam Lee, President & CEO of Northisle stated "We once again have drilled one of the best ever holes drilled on the property at NW23-13.

The 2023 drill program continues to yield gold grades that are much higher than what is typically found in copper porphyries globally. The potential implications of this program are enormous for project as continue to intercept exceptionally high gold grades, near surface, within this extensive porphyry system. Continue to drill actively at Northwest Expo and eagerly await additional assays.

Details of Drilling Results: 2023 drilling has been focused on better defining the mineralized area within Zone 1 with the goal of completing a resource estimate, following relogging of historical drilling, in the context of several drill holes completed by Northisle in 2021 showing important geological features not recognized in the historical drill holes, as well as an extensive surface geophysics program completed on the property during 2022.

Phase 2 drilling commenced in early September and holes NW23-17 and NW23-18 have now been completed to test potential extensions along strike of the existing mineralized envelope at Northwest Expo.

Technical Report on the Island Copper Property - Logging, Sampling and Assaying Procedures: 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.
