ADELAYDE EXPLORATION COMPLETES WORK PROGRAMS ON THE SISSON NORTH TUNGSTEN PROJECT AND THE GEORGE LAKE SOUTH TUNGSTEN ANTIMONY PROJECT IN NEW BRUNSWICK

Adelayde Exploration Inc. has completed two work programs encompassing a helicopter aeromagnetic/radiometric/VLF (very-low-frequency) survey on the company's Sisson North tungsten project and the George Lake South antimony-tungsten project, both located in New Brunswick.

James Nelson, president of Adelayde, stated: "We are pleased to be actively advancing work programs across both our Sisson North tungsten project and our George Lake South tungsten-antimony project as we continue to strengthen our exposure to strategically important critical minerals. Evidenced by strengthening tungsten prices, antimony and tungsten have become increasingly important as governments and industries focus on securing reliable domestic supply chains and reducing dependence on foreign sources. With global supply remaining highly concentrated and demand continuing to expand across defence, energy and advanced technology sectors, we believe these critical materials are positioned to play an increasingly important role in economic and national security. Our geological team is currently under way with reviewing and interpreting the data provided by these two exploration programs. Additionally, we look forward to commencing a gold drill program shortly. Supported by a strong treasury, we remain well financed to aggressively advance our portfolio and generate multiple catalysts across several projects in the months ahead."

The Sisson North tungsten project directly borders the Sisson tungsten mine in New Brunswick. On Nov. 13, the Sisson tungsten mine was selected by the Prime Minister of Canada, Mark Carney, as one of the first nation-building projects. Additionally, on Aug. 7, 2025, Northcliff Resources Ltd. announced it secured approximately $29-million in combined funding from the U.S. Department of Defense and the Canadian government to advance its project. Management cautions that past results or discoveries on properties in proximity to Adelayde may not necessarily be indicative of the presence of mineralization on the company's properties.

Antimony is an essential component in semiconductors and battery storage technology and has several military applications. As trade tensions escalate between China and the United States, where access to raw material units is already tight, restrictions on critical mineral exports from China clearly emphasize the urgent need for Western nations to secure reliable long-term sources of these critical minerals, which are now at the forefront of the global supply chain crisis.
