TSXVenture Exchange Symbol:NCX

VANCOUVER,British Columbia,Oct. 5,2020 -- Northisle Copper and Gold Inc. (TSXV: NCX) ("Northisle" or the "Company") is pleased to announce that the Board of Directors has appointed Sam Lee as President and Chief Executive Officer of Northisle,effective October 5,2020. John McClintock has resigned as President and CEO and will continue with the Company as Vice President,Exploration.

Over the past 20 years Mr. Lee has advised on some of the most prominent M&A,equity,and debt transactions in the international and Canadian global mining industry totalling over $100 billion in value. During this period,he has worked in major resource markets including Toronto,Sydney,and Vancouver where he led various strategic initiatives for CIBC World Markets. Most recently he was Managing Director and head of CIBC's Vancouver Mining Group. Mr. Lee holds a Bachelor of Applied Science,Faculty of Engineering,from the University of Toronto,was a graduate of the Lassonde Mineral Engineering program,and is a CFA charter holder. He also serves on the board of directors of the Vancouver Symphony Orchestra and the Vancouver Symphony School of Music.

Dale Corman,Chairman of Northisle comments: "I am delighted to welcome Sam to Northisle at this pivotal juncture in the Company's strategic plan. Sam's proven success and extensive experience in the global resource industry and capital markets makes him exceptionally qualified to lead us through the next phase of our growth. He is recognized as being highly principled,tenacious,and a thought leader. I look forward to working with Sam in building the leading,globally sustainable mineral resource company.

I would also like to sincerely thank Jack McClintock for his leadership and exceptional work on modeling and demonstrating the enormous exploration potential of the North Island Project over the past nine years. With a positive preliminary metallurgical test result on Red Dog released last Friday (see press release dated October 2,2020) we have completed our technical work and are now in a position to update the Preliminary Economic Assessment ("PEA") to reflect the upside potential related to the expected higher gold and copper recovery rates,inclusion of silver and rhenium metal recovery at Red Dog and Hushamu deposits as well as the higher metal prices."

Sam Lee comments: "I am pleased to have this opportunity to help grow Northisle into a leading mineral resource company whose aim is to benefit all stakeholders and to work closely with its community partners in achieving common goals. When looking at sustainable development opportunities globally,one rarely comes across the trifecta of asset characteristics that are present at Northisle. Specifically,the project has a large defined resource base,an attractive PEA with tangible upside potential,and is located near a historical mining community with exceptional access to clean power,skilled labour,and existing infrastructure. I feel privileged to be working with Dale who successfully developed and then sold Penasquito to Glamis (now Newmont) for $1.2 billion,and Jack who received recognition as PDAC Prospector of the Year for the discovery of the Spence Deposit now owned by BHP. I look forward to working with both in realizing our collective vision."

Jack McClintock comments: "I welcome Sam to the team and look forward to accelerating our exploration program on our highly prospective land package. I am proud of what we have accomplished successfully progressing the project through to PEA optimization and identifying significant upside potential. In addition to the two known deposits there are numerous additional porphyry copper – gold targets on the property including the North Red Dog Extension,the NW Expo 1.5 km long induced polarization anomaly and the 3.5km by 1.5km high-level lithocap currently under option to Freeport – McMoRan."

The Company has approved the granting of stock options to Mr. Lee for the purchase of 4,000,000 common shares of the Company. The options will vest immediately. These options have a five-year term and allow the holder to purchase one common share of the company for $0.12 a share until October 5,2025.

Mineral Resource estimates follow the Canadian Institute of Mining,Metallurgy and Petroleum ("CIM") definitions standards for Mineral Resources and Reserves and have been completed in accordance with the Standards of Disclosure for Mineral Projects as defined by National Instrument 43-101. The NI 43-101 reports co-authored by P Burt PGeo and B Game PGeo documenting the resource estimate available on the company's website and filed on SEDAR. Reported tonnage and grade figures have been rounded from raw estimates to reflect the relative accuracy of the estimate. Minor variations may occur during the addition of rounded numbers. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Copper and gold equivalent calculated using US$3.10/lb Cu,US$1300/oz Au and US$9.00/lb Mo and is not adjusted for mining and metallurgical recoveries as these remain uncertain. The formula used is as follows: CuEQ = (Cu% x 22.0462 x 3.10) + (Au g/t x 1300.00/ 31.1035) + (Mo% x 22.0462 x 9.00)/22.046x3.1. AuEQ =(Cu% x 22.0462 x 3.10) + (Au g/t x 1300.00/ 31.1035) + (Mo% x 22.0462 x 9.00)/(1300/31.1035). Rhenium values have not been used in the cut-off grade or Cu or gold Equivalent calculations.

In September 2017,Northisle published the results of a PEA which demonstrated the potential technical and economic viability of the project constructed as an open-pit mine,with a concentrator processing nominally 75,000 tonnes/day (27Mtpa) with the results summarized in the below table. This PEA is expected to be updated to reflect the results from the metallurgical tests described in the sections above.
