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

Apex Critical Metals Corp. is a Canadian exploration company focused on advancing rare earth element (REE) and niobium projects that support the growing demand for critical and strategic metals across the United States and Canada. The Company's flagship Rift Project, located within the highly prospective Elk Creek Carbonatite Complex in Nebraska, U.S.A., hosts extensive rare earth rights surrounding one of North America's most advanced niobium-REE deposits. Historical drilling across the complex has reported broad intervals of high-grade REE mineralization, including intercepts such as 155.5 m of 2.70% REO and 68.2 m of 3.32% REO.

In Canada, Apex continues to advance its 100%-owned Cap Project, located 85 kilometres northeast of Prince George, British Columbia. The 2025 drill program confirmed a significant niobium discovery with 0.59% Nb?O? over 36 metres, including 1.08% Nb?O? over 10 metres, within a 1.8-kilometre-long niobium trend. The Cap Project continues to demonstrate strong potential for niobium mineralization within a large and previously unrecognized carbonatite system.

With a growing portfolio of critical mineral projects in both Canada and the United States, Apex Critical Metals is strategically positioned to help strengthen domestic supply chains for the minerals essential to advanced technologies, clean energy, and national security. 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.

Forward-looking statements in this news release include (without limitation) statements regarding the Company's US-based prospective assets (more particularly described above), including the potential for additional acquisitions and the potential for exploration, statements regarding the potential for future exploration and drilling to confirm the source of magnetic anomalies, and statements regarding potential opportunities for the Company to engage with prospective strategic and institutional partners and any anticipated benefits thereof. Forward-looking statements are subject to various known and unknown risks and uncertainties that may cause actual results, performance or developments to differ materially from those contained in the statements. Risks that could change or prevent these events, activities or developments from coming to fruition include: the Company's properties are at an early stage of development and no current mineral resources or reserves have been identified by the Company thereof, that we may not be able to fully finance any additional exploration on the Company's properties; that even if we are able to raise capital, costs for exploration activities may increase such that we may not have sufficient funds to pay for such exploration or processing activities; the timing and content of any future work programs; geological interpretations based on drilling that may change with more detailed information; potential process methods and mineral recoveries assumptions based on limited test work and by comparison to what are considered analogous deposits that, with further test work, may not be comparable; testing of our process may not prove successful or samples derived from our properties may not yield positive results, and even if such tests are successful or initial sample results are positive, the economic and other outcomes may not be as expected; the anticipated market demand for REE and other minerals may not be as expected; the availability of labour and equipment to undertake future exploration work and testing activities; geopolitical risks which may result in market and economic instability. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements.
