LONDON / VANCOUVER: 27 October 2026 – Mkango Magnetic Materials Limited (formerly Mkango Resources Ltd.) (AIM:MKA)(TSXV:MKA) (“Mkango”) announces that its wholly-owned subsidiary, Mkango Rare Earths Limited (f/k/a Lancaster Exploration Limited) (“MKAR”), filed a further amendment to its registration statement on Form F-4 (the “Amended Form F-4”) with the United States Securities and Exchange Commission (the “SEC”) on October 26, 2026, in connection with the proposed business combination between MKAR and Crown PropTech Acquisitions (OTC: CPTKW) (“CPTK”) (the “Proposed Business Combination”), initially announced on July 3, 2025. The Amended Form F-4 includes as an exhibit a revised technical report summary on the Songwe Hill Rare Earth Element Project in Malawi prepared in accordance with subpart 1300 of Regulation S-K (the “TRS”).

Additionally, on October 26, 2026, Mkango filed on SEDAR+ a revised technical report on Songwe Hill prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”), entitled “NI 43-101 Updated Technical Report on the Songwe Hill Rare Earth Element Project in Malawi”, with an effective date of June 30, 2025 (the “Revised Technical Report”). The Revised Technical Report was prepared by Phil Bundo of SENET, a DRA Global Group Company, Jeremy Charles Witley of The MSA Group (Pty) Ltd, Scott Swinden of Swinden Geoscience Consultants Ltd, Graham Errol Trusler of Digby Wells Environmental, Clive Wyndham Brown of Bara Consulting (Pty) Ltd and George Papageorgiou of Epoch Resources (Pty) Ltd. Darren L. Smith of Dahrouge Geological Consulting Ltd. acted as a “qualified person” on behalf of Adamas Intelligence Inc. in respect of their sections of the Revised Technical Report. Each of Mr Bundo, Witley, Swinden, Wyndham Brown, Papageorgiou and Smith is a “qualified person” as defined in NI 43-101 and independent of Mkango. The Revised Technical Report supersedes the technical report filed on SEDAR+ on April 30, 2026, but the mineral resource and mineral reserve estimates and the reported economic results remain unchanged. Revisions have been made to the wording in Sections 19 (Market Studies and Contracts) and 22 (Economic Analysis) of the Revised Technical Report.
