APEX CRITICAL METALS CONFIRMS SIGNIFICANT MAGNETIC ANOMALY AT CAP PROJECT, BRITISH COLUMBIA

Apex Critical Metals Corp. has completed and released results from a high-resolution airborne geophysical survey completed at the company's 100-per-cent-owned Cap critical minerals project in central British Columbia.

Highlights:

• Strong magnetic high measuring approximately 2.2 kilometres by 1.8 kilometres with northwest offshoot;
• Magnetic anomaly roughly correlates with the 1.8-kilometre niobium-in-soil trend identified in 2024 and confirmed in 2025 drilling;
• Helicopter-borne magnetic and radiometric survey completed by Precision GeoSurveys Inc.;
• 781 line kilometres flown at 40-metre spacing;
• Assays remain pending for 2,251 metres of core, with results expected shortly.

Sean Charland, chief executive officer of Apex Critical Metals, commented: "The new airborne survey has provided valuable insight into the scale and geometry of the magnetic anomaly, giving us a stronger foundation to evaluate future drill targets and plan the next phase of exploration in 2026. We anticipate receiving assays from the remaining drill holes shortly, which will further guide our understanding of the mineralized system."

The helicopter-borne survey was completed by Precision GeoSurveys of Langley, B.C., on Sept. 15 and 16, 2025, and covered a total of 781 line kilometres at 40-metre line spacing. The program was designed to provide detailed magnetic and radiometric data to assist in mapping the extent and geometry of carbonatite-hosted mineralization at the Cap project.

The airborne magnetic survey delineates a large, well-defined magnetic high measuring approximately 2.2 kilometres by 1.8 kilometres, with a smaller magnetic offshoot extending northwest. The offshoot roughly correlates with the 1.8-kilometre niobium-in-soil trend identified during the 2024 exploration program, which was subsequently confirmed in the subsurface during 2025 drilling. All drill holes completed in 2025 intersected carbonatite and/or associated alteration, with drill hole CAP25-006 returning 0.59 per cent Nb2O5 (niobium pentoxide) over 36.0 metres, demonstrating a spatial correlation between magnetic intensity and niobium mineralization.

Historical drilling completed by the previous operator in 2017 tested the magnetic feature but is interpreted to have not drilled deep enough to intersect the primary source of the anomaly. The offshoot is interpreted to connect to the main magnetic body, suggesting a more extensive carbonatite system than previously recognized.

Magnetic anomalies in carbonatite systems are commonly caused by high magnetite content and associated iron-rich minerals such as pyrrhotite, which can act as geophysical markers for niobium- and rare-earth-element-bearing carbonatites. The strong, coherent magnetic feature at Cap supports and enhances the current geological interpretation developed from Apex's drilling and surface mapping programs.

The interpretation of geophysical data is preliminary in nature. While the magnetic anomaly described is spatially associated with previously intersected carbonatite and niobium mineralization, there is no certainty that the anomaly itself is directly related to mineralization or that it represents the full extent of the carbonatite system. Additional drilling will be required to confirm the source of the magnetic feature.

About Apex Critical Metals Corp.

Apex Critical Metals 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, United States, 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 metres of 2.70 per cent REO (rare earth oxide) and 68.2 metres of 3.32 per cent REO.

In Canada, Apex continues to advance its 100-per-cent-owned Cap project, located 85 kilometres northeast of Prince George, B.C. The 2025 drill program confirmed a significant niobium discovery with 0.59 per cent Nb2O5 over 36 metres, including 1.08 per cent Nb2O5 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 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.
