London, U.K. and Vancouver, CANADA - 16 March, 2023 - Mkango Resources Ltd. (AIM/TSX-V: MKA) (the "Company" or "Mkango") and CoTec Holdings Corp (TSX-V: CTH) ("CoTec") are pleased to announce that they have closed the previously announced £1.5 million investment (the "Investment") by CoTec into Mkango's subsidiary, Maginito Limited ("Maginito"). In connection therewith, Maginito and CoTec have agreed to collaborate on the commercialisation of downstream rare earth technologies in the United States and Mkango Rare Earths UK Ltd ("Mkango UK") has been transferred to become a subsidiary of Maginito.

Maginito now holds a 42% interest in HyProMag Limited ("HyProMag") focused on short loop rare earth magnet recycling in the UK, a 66.8% direct and indirect interest (assuming conversion of Maginito's recently announced convertible loan) in HyProMag GmbH, a company focused on short loop rare earth magnet recycling in Germany, and a 100% interest in Mkango UK, a company focused on long loop rare earth magnet recycling in the UK via a chemical route. A new US subsidiary, to be jointly owned by Maginito and CoTec, is expected to be formed to develop rare earth technology opportunities in the United States.

William Dawes, Chief Executive of Mkango stated: "This is an exciting milestone for Mkango and we look forward to working closely with CoTec through a shared vision for Maginito to create a large-scale, international business focused on downstream rare earth technologies and recycling. Maginito will also benefit from potential synergies with Mkango's development of primary rare earths production in Malawi and Poland. The restructuring of Maginito facilitates future access to capital and creates a strong platform for its scale-up, international roll-out and further partnership opportunities."

Julian Treger, Chief Executive of CoTec stated: "We are glad to have closed this Investment and are now keen to work swiftly with Mkango to roll-out production into North America. Underpinned by unique green processing technologies, our development strategy will be very helpful to establish US independence in the rare earth realm and we hope to make further announcements in the coming months to update the market on this process. These plants are also expected to start generating revenues for CoTec in relatively short order, demonstrating how our growth strategy of applying scalable revolutionary technologies to create profitable green commodity extraction assets works in practice."

About Maginito

Maginito is focused on developing green technology opportunities in the rare earths supply chain, encompassing neodymium (NdFeB) magnet recycling as well as innovative rare earth alloy, magnet, and separation technologies.

Maginito holds a 42% interest in UK rare earth (NdFeB) magnet recycler, HyProMag (www.hypromag.com) with an option to increase its interest to 49%. Hypromag has licensed the patented technology called HPMS (Hydrogen Processing of Magnet Scrap) developed in the Magnetic Materials Group (MMG) at the University of Birmingham.

HyProMag's strategy is to establish short loop recycling facilities for NdFeB magnets at Tyseley Energy Park in Birmingham, U.K. (the "Tyseley Recycling Facilities") and other locations to provide a sustainable solution for the supply of NdFeB magnets and alloys for a wide range of markets including, for example, automotive and electronics. The plant at Tyseley Energy Park is being developed together with the University of Birmingham, with a minimum capacity of 100tpa NdFeB (neodymium, iron, boron) and first production is targeted for 2023. This £4.3 million project is being funded by Driving the Electric Revolution, an Industrial Strategy Challenge Fund challenge delivered by UK Research and Innovation ("UKRI").

In November 2021, HyProMag established an 80%-owned subsidiary in Germany, HyProMag GmbH, to rollout commercialisation of HPMS technology into Germany and Europe. HyProMag GmbH is developing a similar sized plant to that at Tyseley Energy Park (the "HyProMag GmbH Recycling Facility"). Initial capacity is expected to be a minimum of 100tpa NdFeB, comprising recycled rare earth sintered magnets and alloys and will be the first in Germany using the patented HPMS process, with first production targeted for 2024. Maginito has entered into a convertible loan agreement (the "HyProMag GmbH Convertible Loan") with HyProMag GmbH, to acquire up to a 50% interest. Under the terms of the HyProMag GmbH Convertible Loan, Maginito has granted HyProMag GmbH a loan facility for €2.5 million (approximately C$3.6 million) available to be drawn down in accordance with an agreed investment plan and convertible into a 50% interest in HyProMag GmbH.

This investment by Maginito (which will be funded in part by proceeds from Mkango's recently completed £3.5 million placing) will contribute to the matched funding requirements to unlock the €3.7 million (approximately C$5.3 million) grants announced by Mkango on November 23, 2022, for development of the production facility in Baden-Württemberg State.

Mkango UK is establishing a pilot plant at Tyseley Energy Park (the "Mkango UK Pilot Plant") to chemically process recycled HPMS NdFeB powder and magnet swarf (i.e. the powder produced from grinding and finishing magnets) from a range of scrap sources including electronic waste, electric motors and wind turbines, complementing the short loop magnet recycling routes being developed in parallel by HyProMag. The £1.1 million pilot plant programme is being developed as part of the SCREAM Project (https://scream-uk.com/). 70% of the costs are being funded by UK Research and Innovation (UKRI) as part of the Driving the Electric Revolution challenge.
