Adelayde Exploration Closes Acquisition of the Sisson NW Tungsten Project in New Brunswick

Vancouver, British Columbia--(Newsfile Corp. - October 23, 2025) - Adelayde Exploration Inc. (CSE: ADDY) (OTCID: SPMTF) (WKN: A41AGV) (the "Company" or "Adelayde") is pleased to announce, further to its news release on October 14, 2025, the closing of an option agreement with two arm's length vendors (the "Vendors") to acquire the Sisson NW Tungsten Project (the "Property") comprised of 89 claims consisting of approximately 4,890 contiguous acres prospective for tungsten in New Brunswick directly bordering Northcliff Resources Ltd.'s Sisson Tungsten Mine. On August 7, 2025, Northcliff Resources Ltd. announced they secured approximately $29 million CAD in combined funding from the U.S. Department of Defense and the Canadian Government to advance their project. Management cautions that past results or discoveries on properties in proximity to Adelayde may not necessarily be indicative to the presence of mineralization on the Company's properties.

James Nelson, President of Adelayde, stated, "We are excited to now have a significant footprint of 9,780 acres prospective for tungsten at a time when critical metals are receiving increased attention due to recent escalating trade tensions between the USA and China, according to a Reuters report⁽¹⁾. Tungsten and antimony both face tight global supply because China dominates their mining and refining—producing roughly 80-90% of each—while demand continues to rise for use in electronics, defense, and energy technologies. As Western nations seek to secure alternative sources, supply risks and strategic stockpiling are driving higher prices. Adelayde will begin to formulate initial work plans for the Sisson Tungsten and George Lake South Antimony projects, as well as proceeding with the maiden drill program on the Esmeralda County gold project in Nevada in 2025. The Company will be very active for the remainder of 2025 and beyond."

Pursuant to the terms of the option agreement, the Company shall have the exclusive right and option to earn a 100% interest in the Property from the Vendors in consideration for the issuance of a total of 6,000,000 common shares (subject to a four-month hold period) at a deemed price of $0.11 per share and by making cash payment in the amount of $5,000 as set out below:

(a) To pay $5,000 and issue 4,500,000 common shares in the capital of the Company to the Vendors within seven (7) business days of signing the option agreement; and

(b) To issue 1,500,000 common shares in the capital of the Company to the Vendors after the Company has incurred a minimum of $200,000 in exploration expenditures on the Property within eighteen (18) months of signing the option agreement.
