ADELAYDE EXPLORATION ENGAGES GEOLOGIC FIRM FOR WORK PROGRAM ON THE SISSON NORTH TUNGSTEN PROJECT DIRECTLY BORDERING NORTHCLIFF RESOURCES LTD.

Adelayde Exploration Inc. has engaged New-Sense Geophysics Ltd. (NSG) of Markham, Ont., for a work program encompassing a helicopter aeromagnetic/radiometric/VLF (very-low-frequency) survey on the company's Sisson North tungsten project in New Brunswick.

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: "The company is well financed and excited to be hiring a geological team with experience in New Brunswick as we begin working on the Sisson North tungsten project. Critical minerals, and tungsten in particular, have received increased attention in recent years as governments and industry seek to strengthen domestic supply chains and reduce reliance on foreign sources. Critical minerals are increasingly important as supply chains remain highly concentrated and demand continues to grow across defence, energy and advanced technology sectors. This environment, as well as the rising price of tungsten, is driving renewed focus on domestic exploration and development." Mr. Nelson went on to say: "In addition, according to [the Trading Economics website], lithium prices have nearly tripled since June, 2025, and the company recently entered into a joint venture agreement to explore the deepest sections of the only lithium brine basin with production in North America, located in Clayton Valley, Nevada, directly bordering and completely surrounded by energy giant SLB (formerly Schlumberger). We look forward to a very active start to 2026 as the company is well financed to execute multiple planned exploration and work programs, with multiple chances for exploration success."

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.

Adelayde recently announced (Jan. 22, 2026) that it has joined the National Defense Industrial Association (NDIA) in support of the advancement of its critical and strategic mineral portfolio. The NDIA is a U.S.-based organization promoting national security by connecting industry and government.
