NORTH SHORE URANIUM LTD. APPOINTS ANDREW STEWART AS DIRECTOR AND PROVIDES EXPLORATION UPDATE

North Shore Uranium Ltd. has appointed Andrew Stewart to the company's board of directors, effective May 6, 2025, and has provided an update on activities at its Falcon property in the Athabasca basin region of Saskatchewan.

Mr. Stewart's appointment as director

Mr. Stewart is a corporate finance and securities lawyer and a partner in the capital market and securities group at Cozen O'Connor, an AmLaw 100 international law firm. He has over 25 years of capital market experience that includes mergers and acquisitions, public and private equity and debt financings, regulatory compliance, cross-border transactions, and public offerings in Canada and the United States. Mr. Stewart also has served as Securities and Exchange Commission counsel to several U.S. investment banks. He has been a co-founder and counsel for several private and public companies, and is one of the founders of North Shore.

Falcon exploration update

In its Sept. 17, 2024, Oct. 10, 2024, Nov. 13, 2024, and Feb. 27, 2025, news releases, the company summarized work being done at the West Bear and Falcon properties with emphasis on Falcon. Three priority areas have been established at Falcon and zones 1, 2 and 3.

To date, North Shore has identified 36 uranium targets at Falcon. The targets are associated with electromagnetic conductor anomalies, and have been selected based on the analysis and interpretation of multiple geophysical and geologic data sets by North Shore and its consultants. As reported on May 16, 2024, the company discovered near-surface uranium mineralization at drill sites P03 and P08 in an area that had never seen drilling. These new uranium occurrences could be part of a new trend of uranium mineralization in an area that is underexplored. North Shore's near-term focus is to assess the potential for an economic uranium deposit within this trend by evaluating priority EM targets in the south priority area at the eastern end of Zone 1 and the South Walker area at the southern end of Zone 2. The company will continue prioritizing and analyzing targets in preparation for future prospecting and drill programs. Updates on target prioritization and exploration efforts will be provided on a continuing basis.

Brooke Clements, president and chief executive officer of North Shore, stated: "The North Shore team is happy to welcome Andrew Stewart to its board of directors. His expertise and enthusiasm will be a great benefit to the company. New uranium deposits will be required to fuel the reactors that will be needed for the growing nuclear power industry. We believe that Saskatchewan's Athabasca basin is the best jurisdiction in the world for uranium exploration and development and that there is good potential to discover a new, high-grade uranium deposit. North Shore's pipeline of uranium targets at Falcon and West Bear give it exposure to making a significant new discovery."

Falcon background information

Falcon consists of 15 mineral claims totalling 55,503 hectares. Four of the claims comprising 12,791 hectares are 100 per cent owned by the company, and the remaining 11 claims are subject to an option agreement with Skyharbour Resources Ltd. Under the terms of the option agreement, North Shore has the option to earn an 80-per-cent interest in the 11 claims by completing certain payments, exploration work and other commitments by October, 2026. Falcon is located 30 kilometres east of the active Key Lake uranium mill and former mine. Between 1983 and 2002, the mine produced a total of 209.9 million pounds of triuranium octoxide at an average grade of over 2.0 per cent.

About North Shore Uranium Ltd.

The nuclear power industry is in growth mode as more nuclear power will be required to meet the world's ambitious carbon dioxide emission reduction goals and the needs of new power-intensive technologies like artificial intelligence. In this environment, new discoveries of economic uranium deposits will be very valuable, especially in established uranium-producing areas like Saskatchewan. North Shore is working to become a major force in exploration for economic uranium deposits. The company is working to achieve this goal by exploring its Falcon and West Bear properties at the eastern margin of the Athabasca basin and by evaluating opportunities to complement its portfolio of uranium properties.
