VANCOUVER, BC / ACCESS Newswire / June 16, 2026 / Apex Critical Metals Corp. (CSE:APXC)(OTCQX:APXCF)(FWB:KL9) ("Apex" or the "Company"), a mineral exploration company focused on advancing its strategic 100%-controlled Rift Rare Earth Project (the "Rift Project") within the Elk Creek Carbonatite Complex in southeastern Nebraska, U.S.A., is pleased to announce that the Company filed a technical report for the Rift Project entitled " NI 43-101 Technical Report on the Rift Project, Johnson and Pawnee Counties, Nebraska, USA " with an effective date of May 15, 2026, prepared for Apex by Robin J. Wilson, B.Sc. (Hons) Geology, MAusIMM, MAIG (the "Technical Report"). The Technical Report was prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") and is available under the Company's issuer profile on SEDAR+ (available at www.sedarplus.ca ). 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 deposits. Two historical drillholes located within the 700 m corridor of interest returned broad intervals of >2.00% REO, with higher grade (>3.00% REO) intervals within. The Company's 2026 drilling has continued to demonstrate this grade profile and have expanded the footprint of the high-grade mineralization ("Trinity Zone) over approximately 380 m from the historical drillholes to-date.

Additionally, drilling has delineated a new deeper horizon ("Neo Zone") of strongly elevated NdPr beneath the high-grade material with NdPr distributions between 30-50%. For more information, please see the Company's news releases dated April 7, 2026, April 28, 2026, May 6, 2026 and May 15, 2026, which are available under the Company's issuer profile on SEDAR+ (available at www.sedarplus.ca ). 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 an emerging niobium discovery with 0.59% Nb₂O₅ over 36 metres, including 1.08% 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.
