Mkango Magnetic Materials Limited Announces Filing of Amended Form F-4 by Mkango Rare Earths Limited

London / Vancouver: 30 September 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 an 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 September 29, 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 comprises a preliminary proxy statement of CPTK and a preliminary prospectus of MKAR in respect of the common shares and warrants to be issued in the Proposed Business Combination. A copy of the Amended Form F-4 is available on EDGAR at the following hyperlink: https://www.sec.gov/ix?doc=/Archives/edgar/data/2052373/000121390026104835/ea0271516-14.htm, and will be filed under Mkango’s profile on SEDAR+ at www.sedarplus.ca. The Amended Form F-4 has not yet been declared effective by the SEC and the information it contains is subject to completion or amendment. Subject to completion of the SEC review process and satisfaction of customary closing conditions, including approval by CPTK’s shareholders, MKAR’s common shares and warrants are expected to list on Nasdaq under the symbols “MKAR” and “MKARW” on closing.

The Amended Form F-4 has not been reviewed or approved by any Canadian or United Kingdom regulatory authority, does not constitute a prospectus under Canadian or United Kingdom securities laws, and does not constitute an offer of securities in those jurisdictions. The content of the Amended Form F-4 has not been approved by an authorised person within the meaning of the United Kingdom Financial Services and Markets Act 2000.

About Mkango Magnetic Materials Limited

Mkango is listed on the AIM and the TSX-V Stock Exchanges. Mkango’s corporate strategy is to become a market leader in the production of recycled rare earth magnets, alloys and oxides, through its interest in Maginito Limited (“Maginito”), which is owned 79.4 per cent by Mkango and 20.6 per cent by CoTec Holdings Ltd (“CoTec”), and the Remloy business acquired by its wholly owned German subsidiary, to develop new sustainable sources of neodymium, praseodymium, dysprosium and terbium to supply accelerating demand from electric vehicles, wind turbines and other clean energy technologies.

Maginito holds a 100 per cent interest in HyProMag Limited and a 90 per cent direct and indirect interest (assuming conversion of Maginito’s convertible loan) in HyProMag GmbH, focused on short loop rare earth magnet recycling and manufacturing in the UK and Germany, respectively, and a 100 per cent interest in Mkango Rare Earths UK Ltd (“Mkango UK”), focused on long loop rare earth magnet recycling in the UK via a chemical processing route.

Maginito and CoTec are also expanding HPMS recycling technology into the United States via the 50/50 owned HyProMag USA joint venture company.

Remloy has developed a plant in Bitterfeld, Germany, which recycles end-of-life rare earth magnets via a melting process (medium loop rare earth magnet recycling) to produce neodymium-iron-boron (“NdFeB”) alloy powders for the bonded and hot deformed magnet markets, complementary to HyProMag’s short loop recycling process, to produce sintered magnets, and to Mkango UK’s long loop recycling process, to produce mixed rare earth carbonates and oxides.

Mkango currently owns 100% of the advanced stage Songwe Hill rare earths project in Malawi and the proposed Pulawy rare earths separation plant in Poland. On grant of the large-scale mining licence the Government of Malawi may elect to take a free 10% interest in the entity holding that licence. Both the Songwe and Pulawy projects have been selected as Strategic Projects under the European Union Critical Raw Materials Act. Songwe has also received Development Funding from the U.S. International Development Finance Corporation (DFC), the U.S. Government’s development finance institution, securing US$4.6 million in reimbursable funding for Front End Engineering and Design. MKAR has signed a Business Combination Agreement with CPTK to list the Songwe Hill and Pulawy rare earths projects on NASDAQ via a SPAC merger under the name Mkango Rare Earths Limited.
