NORTH SHORE URANIUM LTD. ANNOUNCES EXTENSION TO FALCON PROPERTY OPTION AGREEMENT AND PROVIDES FALCON EXPLORATION UPDATE

The term of North Shore Uranium Ltd.'s South Falcon option agreement with Skyharbour Resources Ltd. has been extended from three to four years. The agreement governs exploration activities on 11 of the 15 mineral claims that constitute the company's Falcon property located in the Athabasca basin region of Saskatchewan. North Shore is currently preparing for future exploration programs at Falcon.

South Falcon option agreement amendment

On May 26, 2023, North Shore Energy Metals Ltd., a wholly owned subsidiary of the company, entered into the agreement with Skyharbour. Under the terms of the agreement, the company has the right to earn an up-to-100-per-cent interest in 11 Falcon claims totalling 42,512 hectares by completing certain cash payments, share issuances and exploration expenditure commitments over a three-year period commencing on Oct. 31, 2023. The agreement has been amended, with the term being extended from three to four years. Commitments formerly required on or before Oct. 31, 2025, are due on or before Oct. 31, 2026, and commitments required by Oct. 31, 2026, are due on or before Oct. 31, 2027. In consideration for the term extension, North Shore has agreed to issue Skyharbour 500,000 common shares of the company at a deemed price of 3.5 cents per consideration share. Issuance of the consideration shares is subject to the approval of the TSX Venture Exchange. The consideration shares are subject to a four-month-plus-one-day hold period upon issuance.

Brooke Clements, president and chief executive officer of North Shore, stated: "We are pleased with the extension on the term of the agreement with Skyharbour from three to four years. The extra time will allow us to optimize our systematic and efficient exploration programs at Falcon. Our team believes that Saskatchewan's Athabasca basin is the best jurisdiction in the world for uranium exploration and development and that our work has shown that Falcon offers great potential for a new signficant uranium discovery."

Falcon exploration update

In its Sept. 17, 2024, Oct. 10, 2024, Nov. 13, 2024, Feb. 27, 2025, and May 6, 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 zones 1, 2 and 3, and 36 uranium targets within the three zones have been selected to date 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 within the south priority area in an underexplored area that had never seen drilling. The company's top priority at Falcon is to investigate uranium targets along an electromagnetic conductor trend that includes these two new uranium occurrences. At FA003, the electromagnetic conductor system and an associated magnetic low are disrupted, and the interpreted structural system splits, with one arm going to the northeast and the other to the north-northeast. In addition, there is an associated gravity low anomaly identified from the 2022 airborne survey data. The combination of the disruptions and change in orientation of the electromagnetic trend, as well as the magnetic and gravity lows, can be indicative of the alteration footprint associated with a uranium mineralizing system.

The company will continue planning for future prospecting and drill programs focused on targets like FA003. Research on existing targets and structural corridors will continue and updates will be provided on a continuing basis.

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 the agreement with Skyharbour described above. 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.

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.
