NorthIsle Copper and Gold

August was another busy month of site visits at our North Island Project.

Investor interest in Northisle continues to build, especially since publishing our updated Mineral Resource Estimate a few weeks ago. The updated resource now includes 1.2 billion tonnes of Indicated Resources containing 10.1 billion lbs of copper equivalent or 16.2 million oz of gold equivalent, providing a strong foundation as we advance toward a PFS in Q1 2027.

With a favourable commodity price environment for both copper and gold, it is an exciting time to be advancing one of Canada’s most significant copper-gold development projects. Site visits provide an opportunity to see what differentiates the North Island Project first hand: existing infrastructure, a district-scale land package, exploration upside, and the ongoing work to systematically de-risk project development. We appreciate the continued interest and look forward to welcoming more visitors to northern Vancouver Island.

Northisle President & CEO, Sam Lee, recently updated investors on the company's latest achievements. With Indicated Resources containing over 10 billion pounds of copper equivalent, a healthy treasury to advance permitting and development work, more exploration drilling underway, and a PFS expected in Q1 2027, the second half of 2026 will be catalyst rich.

What stands out most is the combination of development visibility and district-scale exploration upside. Northisle controls roughly 40 km of a 50 km porphyry district on northern Vancouver Island, supported by established infrastructure and four known deposits. With a multi-phased exploration program ongoing alongside consistent activity on its PFS, Northisle is positioned to continue driving value through project development and growth through exploration.

Northisle CEO, Sam Lee, recently joined Michael McCrae of Mining Stock Daily to discuss the North Island Project’s updated Mineral Resource Estimate, which increased indicated resources by 36% to approximately 1.2 billion tonnes. Within that mineral inventory are 405 million tonnes of higher-grade indicated resources grading ~0.5% copper equivalent, an important consideration as Northisle evaluates mine sequencing, capital intensity, and the potential for stronger margins in the earlier years of its operation.

With a PFS targeted for Q1 2027, Northisle continues to advance project optimization and de-risking while simultaneously highlighting future growth potential across its 100% owned, 40km copper-gold district. Northisle's ability to drive value and growth in unison is a true differentiator at an increasingly important time for the mining sector.

Northisle was pleased to attend Agentis Capital’s exclusive BC & Yukon Mining Summit this week. The summit connected mining executives, institutional investors, financiers, and analysts for meaningful discussions on investment and development opportunities throughout Western Canada. We were also happy to see BC’s Minister of Mining and Critical Minerals, the Honourable Jagrup Brar, in attendance – a testament to the critical need for open dialogue between government, industry, and capital markets to drive responsible resource development.

These discussions come at an important time when copper, gold, and critical minerals are increasingly recognized as strategically important to Canada and the larger global economy. Events like these allow us to highlight the quality of the North Island Project as well as the investment, policy leadership, and long-term thinking necessary to execute on development.

Vancouver, B.C. – Northisle Copper and Gold Inc. (TSX-V: NCX, OTCQX: NTCPF) (“Northisle” or the “Company”) is pleased to announce the release of an integrated mineral resource estimate for its 100% owned North Island Project (the “2026 Resource Estimate”), which integrates the Northwest Expo, Red Dog, West Goodspeed, and Hushamu deposits. The 2026 Resource Estimate will be used for the development of a pre-feasibility study (“PFS”) on the North Island Project, which remains on target for completion in Q1 2027.

Alex Davidson, Chairman, noted “This integrated resource update represents another important milestone for Northisle and is a critical step towards the completion of the North Island Project PFS. With 10.1 billion pounds of copper equivalent or 16.2 million ounces of gold equivalent contained in Indicated Resources, the 2026 Resource Estimate is finally beginning to tell the story of the district-scale potential of the North Island Project.”

Sam Lee, President & CEO, stated “Over the past 18 months, we have either achieved or exceeded each of the goals we set in respect to resource growth and conversion. At West Goodspeed, we added over 113 million tonnes of Indicated Resources with 873 million lbs Cu Eq., or 1.2 million oz Au Eq. in contained metal. At Northwest Expo, we successfully converted Inferred material, increasing Indicated tonnage by 133%, and expanded the resource along strike. Significantly, at Red Dog, we increased contained copper equivalent metal in Indicated Resources by 30% and plan to investigate the connection between Red Dog and West Goodspeed with additional drilling in 2026. We additionally increased our exposure to critical
minerals beyond copper, adding 68 million lbs Mo and 362,000 lbs Re in Indicated Resources. These results, in addition to improved commodity prices, have driven meaningful resource growth and provide a solid foundation for the North Island Project PFS, which remains on target for completion in Q1 2027.”

It is always rewarding whenever analysts and investors take the time to visit our North Island Project and see first-hand the progress we are making on the ground. We have been busy hosting tours this summer and look forward to several more this year!

As we continue to work towards an updated Mineral Resource Estimate and Pre-Feasibility Study, visits like these help illustrate how we are advancing multiple value drivers simultaneously – delivering value alongside growth. Some recurring themes from the visits so far include the value of existing infrastructure and a strategic location, as well as the impact of implementing new tools like Veracio's Scan technology to improve exploration efficiency and targeting.

We are grateful to everyone who took the time to learn about our project, and look forward to continuing to highlight the potential of the North Island Project as one of the world's most developable copper-gold opportunities.

Northisle Copper & Gold was recently featured in Mining Journal, which highlighted the potential of the North Island Project as one of Canada’s top copper-gold development opportunities. The article notes the district-scale potential of the North Island Project, the staged development approach of the 2025 PEA, the infrastructure available in British Columbia and copper’s increasing allure with long-term demand tied to global electrification.

The key takeaway is that Northisle is progressing multiple fronts at the same time: advancing project development and permitting, expanding the resource base through exploration, and demonstrating robust project economics. As Northisle continues to advance its strategy to deliver both value and growth, ex*****on on these milestones will present important catalysts.

What an amazing weekend for Filomi Days 2026! We at Northisle were proud to once again sponsor this much loved Port Hardy tradition. It was a joy to celebrate with our neighbours, local businesses, and community partners. Whether it was the parade, live entertainment, family activities, or fireworks we loved seeing so many come together to celebrate everything that makes the North Island so unique; our industries, history and sense of community.

Thanks to the organizers, volunteers, performers and everyone who came out to enjoy the weekend. We’re proud to be a part of such an amazing community and can’t wait for Filomi Days 2027! 💙🎉
