About Mkango Resources Ltd.

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 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 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 route.

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

Mkango currently owns 100% of the advanced stage Songwe Hill rare earths project in Malawi and the proposed Puławy rare earths separation plant in Poland. Both the Songwe and Puławy projects have been selected as Strategic Projects under the European Union Critical Raw Materials Act.
