ADELAYDE EXPLORATION COMMENCES WORK PROGRAM ON THE GEORGE LAKE SOUTH ANTIMONY TUNGSTEN PROJECT IN NEW BRUNSWICK

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

The George Lake South antimony-tungsten project is located in the direct vicinity of the Lake George antimony mine in New Brunswick, which was operated intermittently from 1876 to 1996. The Lake George antimony mine was once North America's largest primary antimony mine and contains an estimated 800,000 tonnes of antimony-bearing ore, based on a historical technical report. At current prices of $22 per pound, this represents an estimated value between $933-million and $1.05-billion. 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 George Lake South antimony-tungsten project. Critical minerals such as antimony and tungsten have become increasingly important as nations and industries focus on securing reliable domestic supply and reducing reliance on overseas producers. As global supply remains concentrated in only a few regions and demand expands across defence, clean energy and high-tech manufacturing, these critical materials are playing an evermore essential role in economic and national security." Mr. Nelson went on to say: "We're currently under way with two work programs and we expect to also commence a gold drill program shortly. We are well financed for all of our planned work programs and we will have several catalysts ahead of us across multiple projects.

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.

In recent news announced on April 27, 2026, Adelayde commenced work on the Sisson North tungsten project, which 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 (Canadian) 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.

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.
