NORTHISLE ANNOUNCES UPDATE ON THE NORTH ISLAND PROJECT AND EARLY OPTION EXERCISE BY CEO

NorthIsle Copper and Gold Inc. has provided an update on the company's continuing technical, exploration and corporate activities.

The company has recently completed the previously announced preliminary project trade-off work and has retained Ausenco Engineering Canada ULC to prepare a new Preliminary Economic Assessment on the North Island Project (the "2024 PEA"). The 2024 PEA is anticipated to evaluate an integrated project incorporating the Hushamu, Red Dog and Northwest Expo deposits, with the staged development of a processing facility located near the Hushamu deposit.

In support of the 2024 PEA, NorthIsle has initiated an integrated updated resource estimate for the North Island Project which includes the Hushamu, Red Dog and Northwest Expo deposits, which will incorporate all drilling completed through the end of 2023. The completion of this integrated estimate is targeted for early Q3 2024, with a Technical Report targeted for completion by mid-Q3 2024. Following completion of the updated integrated mineral resource estimate, the Company is targeting completion of the 2024 PEA by Q4 2024.

Drilling at West Goodspeed has progressed rapidly with good drilling conditions supporting the completion of 5 drill holes totalling more than 2,120m to date. Assays remain pending on these drill holes. Drilling at West Goodspeed is targeted to step out from the December 2023 discovery drill holes described in the Company's press release titled "NorthIsle Makes New Discovery of Near Surface Copper-Gold Porphyry with multiple intercepts at West Goodspeed" dated December 6, 2023 (https://bit.ly/westgoodspeeddiscovery) which included an intercept of 125m starting near surface and grading 0.49% Cu Eq. NorthIsle's 2024 exploration program is described further in its May 23, 2024 press release titled "NorthIsle Commences 2024 Phase I Exploration Program" (https://bit.ly/2024exploration).

Drilling continues at West Goodspeed and is anticipated to move to Northwest Expo in the coming weeks where NorthIsle has planned in-fill and step out drilling with a goal of vectoring towards the anticipated porphyry source of the lithocap-hosted mineralization at Northwest Expo.

Mr. Lee stated "The progress we have made at NorthIsle since reactivating the Company in 2020 has been outstanding. We have progressed the North Island Project considerably, strengthened our partnerships with First Nations, Provincial and Federal Governments, and have built an exceptional team. My conviction in NorthIsle is strong and I am therefore very pleased to be exercising my options early."

Sam Lee, President & CEO of NorthIsle has elected to early exercise 4,000,000 share options having an expiry date of October 5, 2025. The option exercise proceeds of $480,000 will be used to advance the 2024 PEA. Post exercise, Mr. Lee will own 7,318,616 shares, 740,201 restricted share units, and 2,317,500 options.
