ADELAYDE EXPLORATION COMMENCES WORK PROGRAM ON THE SISSON NORTH TUNGSTEN PROJECT DIRECTLY BORDERING NORTHCLIFF RESOURCES LTD.

A work program encompassing a helicopter aeromagnetic/radiometric/VLF (very-low-frequency) survey on Adelayde Exploration Inc.'s Sisson North tungsten project in New Brunswick is now under way.

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.

James Nelson, president of Adelayde, stated: "We are pleased to now be under way with the work program on our Sisson North tungsten project. Fundamentals for tungsten are strong right now and this is an important step in unlocking the potential of this asset. Critical minerals -- particularly tungsten -- have garnered increasing attention in recent years as governments and industry work to strengthen domestic supply chains and reduce dependence on foreign sources. With supply chains remaining highly concentrated and demand rising across defence, energy and advanced technology sectors, the importance of these materials continues to grow. This backdrop, combined with strengthening tungsten prices, is driving renewed focus on domestic exploration and development. We are well financed for this work program, which will allow us to be very active across multiple projects for the remainder of the year."

Adelayde recently announced (Jan. 28, 2026) it entered into a joint venture agreement (JV) to explore the deep basin lithium brine potential in Clayton Valley, Nevada. The 115 mineral claims comprising the 2,300-acre JV land package are all located within and completely surrounded by SLB (formerly Schlumberger) and Pure Energy Minerals' lithium deposit. Clayton Valley, Nevada, is the only long-established producing lithium brine basin in the United States, home to Albemarle's Silver Peak lithium brine mine, which extracts lithium from subsurface brines. It has been the sole U.S. producing lithium brine operation since the 1960s.

About Adelayde Exploration Inc.

Adelayde's projects include three lithium projects in Clayton Valley, Nevada: the 1,136-acre McGee lithium clay deposit, which has a mineral resource estimate of 320 million tonnes at 803 parts per million lithium for 1,369,000 indicated tonnes of lithium carbonate equivalent (LCE) and 157 million tonnes at 865 per million lithium for 723,000 inferred tonnes of LCE, directly bordering SLB (formerly Schlumberger) and Century Lithium Corp.; the 280-acre Elon lithium brine project, which has access to some of the deepest parts of the only lithium brine basin in production in North America; and the 124-acre Green Clay lithium project. The company also holds the 248-acre Clayton Ridge gold project in Esmeralda county, Nevada; the 4,722-acre George Lake South antimony project; and the 9,780-acre Sisson North tungsten project, both located in New Brunswick.
