(CSE:APXC)(OTCQX:APXCF)(FWB:KL9)("Apex" or the "Company"), a Canadian mineral exploration company focused on the identification and development of critical and strategic metals, is pleased to announce the establishment of its Technical Advisory Board (TAB) and welcomes the appointment of its inaugural member Alex Knox, P.Geo.

The technical advisory board will provide strategic guidance and technical expertise to support the advancement of the Company's growing portfolio of high-potential projects.

Alex Knox, P.Geo., is a Calgary, Alberta-based geologist with over five decades of experience in mineral exploration. He brings unparalleled expertise regarding rare earth elements (REE), niobium, and other critical metals. His distinguished career includes key roles at major organizations such as Unocal Canada Ltd. and Molycorp, where he contributed to significant discoveries and developments in industrial minerals, uranium, and base metals. As an independent consultant through AWK Geological Consulting Ltd., Mr. Knox has been instrumental in advancing REE projects across Canada, the United States, and South America, with a particular focus on carbonatite-hosted systems known for their potential in hosting economically viable REE and niobium deposits.

"Alex's appointment marks an important milestone for Apex as we build a world-class advisory team to drive our exploration and development efforts, "says Sean Charland, CEO of Apex.

About Apex Critical Metals Corp. (CSE: APXC) (OTCQX: APXCF) (FWB: KL9)

Apex Critical Metals Corp. is a Canadian exploration company specializing in the acquisition and development of properties prospective for carbonatites and alkaline rocks with potential to host economic concentrations of rare earth elements (REE's), niobium, gold and copper mineralization. Apex's Cap Property located 85 kilometres northeast of Prince George, B.C., spans 25 square kilometres and hosts a recently identified promising 1.8-kilometre niobium in soil trend. The Company's Bianco carbonatite Project encompasses 3,735 hectares covering a large carbonatite complex within an area known for significant niobium mineralization in northwestern Ontario. The Lac Le Moyne Project covers approximately 4,025 ha and is situated several kilometers to the northwest of Commerce Resources Corp.'s Eldor Carbonatite Complex located in Quebec, Canada.

Carbonatites are extremely rare rock types, with around 600 known worldwide. They are host to rare earth element ("REE") minerals, niobium, tantalum and phosphate, as well as copper and gold. Carbonatites are host to the world's largest and most productive niobium deposits, including Araxa and Catalão in Brazil, and Niobec in Quebec. In addition, they are the primary source of REEs, including Mountain Pass in California, Mount Weld in Australia, and Bayan Obo in China. They are also important sources of phosphate (apatite), including Cargill, Ontario, while the Palabora mine in South Africa has produced copper, nickel, gold, magnetite, and vermiculite. Other carbonatites are known to have produced gold, iron, zirconium, fluorite, and other industrial minerals.

By acquiring a multitude of carbonatite projects, Apex intends to investigate potential high-value opportunities to meet the growing global demand of specialty metals across various industries. Apex is publicly listed in Canada on the Canadian Securities Exchange (CSE) under the symbol APXC and quoted on the OTCQX market in the United States under the symbol APXCF, and in Germany on the Borse Frankfurt under the symbol KL9 and/or WKN: A40CCQ.
