APEX CRITICAL METALS ADVANCES EXPLORATION PROGRAMS FOR NEW PROJECTS IN EASTERN CANADA

The 2025 field exploration programs at Apex Critical Metals Corp.'s newly acquired Bianco and Lac Le Moyne projects will commence in June. Apex has engaged Dahrouge Geological Consulting Ltd. to undertake the fieldwork for the two projects planned for this summer.

Dahrouge is recognized worldwide for its expertise in the exploration and discovery of critical elements. Both projects are proximal to known carbonatite complexes that show rare earth element (REE) and niobium-tantalum (Nb-Ta) mineralization. Carbonatites are extremely rare rock types, with just over 600 showings known worldwide. They are host to REE minerals, niobium, tantalum, phosphate, fluorite and iron, as well as copper and gold. Carbonatites are host to the world's largest and most productive niobium and REE deposits.

Sean Charland, chief executive officer of Apex Critical Metals, comments: "The company is laser focused on commencing this inaugural exploration program on our newly acquired properties, which are considered to have excellent potential for niobium, rare earth and phosphate mineralization. Critical minerals are at the forefront of clean technology and advanced manufacturing, and by expanding our portfolio into eastern Canada, we are positioning the company in the midst of the evolving critical minerals markets."

Bianco project

The Bianco carbonatite project is located in Northwestern Ontario approximately 12.5 kilometres (km) southwest of the Kingfisher Lake First Nation and 156 km north of the town of Pickle Lake. Consisting of 85 single-cell mining claims totalling approximately 3,735 hectares (ha), the property is characterized by a geophysical magnetic anomaly, which is situated approximately midway between the Schryburt Lake and Big Beaver House carbonatite projects, both with known Nb and REE mineralization.

A 10-day surface geological mapping and sampling program is planned for mid-June and will be based out of Pickle Lake, Ont. Field personnel will traverse the property while focusing exploration efforts on targets, such as the magnetic anomaly and potential outcrop observed through satellite imagery. Additional targets will be refined based on preliminary field observations to ensure full property coverage. Soil sampling grids are planned to cover areas with little to no outcrop exposure in order to develop a comprehensive geochemical data set across the project.

No prior exploration activities have been conducted at Bianco, highlighting its potential as a promising target for future mineral discovery.

Lac Le Moyne project

The Lac Le Moyne carbonatite project is located in northeastern Quebec, near the community of Kuujjuaq, consisting of 86 map-staked claims totalling approximately 4,025 ha and situated several kilometres to the northwest of Commerce Resources Corp.'s Eldor carbonatite complex.

A two-week surface geological mapping and sampling program is planned to start during the first week of July and will be based out of Kuujjuaq. Field personnel will traverse the property while focusing on the multiple carbonatite outcrops identified and mapped by government geologists in the 1970s. Additional targets are based on follow-up of historical rock and sediment samples. Outcrop mapping and sampling will be supported by soil sampling to cover areas with little to no outcrop exposure to develop a comprehensive geochemical data set across the project. Additional targets will be refined based on preliminary field observations to ensure full property coverage.

The company cautions that past results or discoveries on adjacent properties ( Eldor, Schryburt Lake, Big Beaver House) may not necessarily be indicative to the presence of mineralization on the company's properties (Lac Le Moyne, Bianco).

Marketing agreement

Apex Critical Metals is also pleased to announce it has signed an agreement with Zimtu Capital Corp., whereby Zimtu will provide marketing services under its Zimtu Advantage program, effective June 1, 2025, for an initial term of 12 months at a cost of $12,500 per month. The program is designed to provide strategic marketing support, investor engagement and public awareness initiatives. Services include investor presentations, e-mail marketing, lead generation campaigns, blog posts, digital campaigns, social media management, Rockstone Research reports and distribution, video news releases, and related marketing and awareness activities. Zimtu is based in Vancouver, at Suite 1450, 789 West Pender St., Vancouver, B.C., V6C 1H2. Zimtu's compensation does not include securities of the company. Zimtu currently owns 4,951,226 shares and 5,303,336 common share purchase warrants of the company and is a non-arm's-length party to the company (as that term is defined in the policies of the TSX Venture Exchange) by virtue of the two companies sharing common directors (Mr. Charland is a director and officer of Zimtu, and a director and officer of the company) and officers (Jody Bellefleur is chief financial officer of Zimtu, and CFO and a director of the company). The company's entry into the Zimtu agreement was approved by the company's board of directors absent Mr. Charland and Ms. Bellefleur, who disclosed their relationship with Zimtu and recused themselves.

About Apex Critical Metals Corp.

Apex Critical Metals 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 (REEs), 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 hectares and is situated several kilometres to the northwest of Commerce Resources's Eldor carbonatite complex in Quebec, Canada.

Carbonatites are extremely rare rock types, with fewer than 600 known worldwide. They are host to 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 Catalao 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 in 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 under the symbol APXC, in the United States on the OTCQB market under the symbol APXCF, and in Germany on the Borse Frankfurt under the symbol KL9 and/or WKN: A40CCQ.
