ADELAYDE EXPLORATION JOINS THE CANADIAN ASSOCIATION OF DEFENCE AND SECURITY INDUSTRIES (CADSI)

Adelayde Exploration Inc. has joined the Canadian Association of Defence and Security Industries (CADSI) in support of the continuing advancement of the company's critical and strategic mineral portfolio. The CADSI is the national voice of Canada's defence, security and cyber sectors and a key organization supporting collaboration between industry, government and military stakeholders.

James Nelson, president of Adelayde, stated: "As critical minerals are becoming paramount to domestic security, we felt that this is a crucial time to join the CADSI, demonstrating our commitment to supporting secure, responsible and strategically aligned development of critical minerals within Canada. We are excited to begin work shortly on the Sission North tungsten project in New Brunswick, a jurisdiction that is very supportive of mining. We are also currently formulation work plans for the George Lake South antimony project in New Brunswick. The company is well funded and will be very active for the remainder of 2026."

Membership in CADSI provides the company with access to defence industry forums, policy roundtables, technical workshops and networking opportunities that support collaboration across Canada's defence and security community. Participation in CADSI will help the company remain informed on emerging capability needs, procurement trends, regulatory considerations and partnership opportunities relevant to critical minerals and advanced materials vital to national and allied security.

The company has now joined defence associations both in Canada and in the United States under the National Defence Industrial Association (NDIA) in support of the advancement of its critical and strategic mineral portfolio.

Adelayde management is optimistic to be able to leverage relationships established through membership in the CADSI and the NDIA to help advance the company's critical minerals projects. These projects include the 9,780-contagious-acre Sisson North tungsten project in New Brunswick directly bordering Northcliff Resources Ltd.'s Sisson tungsten mine, the 4,722-acre George Lake South antimony project in New Brunswick, Canada, and 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 parts per million lithium for 723,000 inferred tonnes of LCE, directly bordering SLB (formerly Schlumberger) and Century Lithium Corp.
