Mkango Subsidiary, Maginito, and CoTec Form US Joint Venture

LONDON, UK and VANCOUVER, BC / ACCESSWIRE / September 14, 2023 / CoTec Holdings Corp. (TSXV:CTH)(OTCQB:CTHCF) ("CoTec") and Mkango Resources Ltd. (AIM/TSX-V: MKA) ("Mkango") are pleased to announce that CoTec and Maginito Limited ("Maginito") have entered into a binding letter agreement pursuant to which they have agreed a 50:50 joint venture (the "Joint Venture") in relation to the United States roll-out of HyProMag's rare earth magnet recycling technology. HyProMag's technology will be sublicenced to the new Joint Venture company, HyProMag US, on formation.

HyProMag is 100 per cent owned by Maginito Limited ("Maginito"), which is owned on a 90:10 basis by Mkango and CoTec. HyProMag is commercialising rare earth magnet recycling using Hydrogen Processing of Magnet Scrap (HPMS) technology in the UK, Germany and United States, with first production expected in the UK in 2023 and in Germany in 2024. Revenue from the US Joint Venture is targeted for 2025/2026.

The Joint Venture will initially be focused on completing a scoping study and a bankable feasibility study ("Feasibility Study") for the deployment of three HPMS vessels utilizing the HyProMag technology and one magnet manufacturing facility in the US (combined the "US Project"). The Feasibility Study is expected to be completed in 2024. Following completion of the Feasibility Study, CoTec and Mkango would make a joint decision on whether the Joint Venture will proceed with the construction of the US Project.

CoTec will fund the initial operations of the Joint Venture, including the costs of the Feasibility Study. If the Joint Venture proceeds with the construction of the US Project, CoTec will also be responsible for funding all the development costs of the US Project, with a total expected funding of £30 million to £50 million during the first three years post completion of the Feasibility Study, subject to results of the Feasibility Study. All funding provided by CoTec would be in the form of shareholder loans. CoTec and Mkango also expect that the Joint Venture will seek US government funding for the US Project.

The parties have agreed that certain long lead items could be pre-ordered to expedite, subject to approval, the development of the US Project. A comprehensive joint venture agreement dealing with all other commercial aspects of the US Project, consistent with the terms of the existing cooperation agreement between CoTec and Mkango, will be agreed by the parties in parallel with the completion of the Feasibility Study.

Julian Treger, CoTec CEO commented; "This is a major step forward for CoTec and Mkango/Maginito and we are looking forward to working with the Mkango and HyProMag teams on this very exciting, proven and much needed technology in the US targeting the long-term supply of low cost, sustainable recycled rare earth magnets.

"The US presents a significant opportunity for the HyProMag technology and the technical skills of Mkango and HyProMag combined with CoTec's commercial strength could potentially provide shareholders with a unique and robust value proposition in the rare earth industry in the right jurisdiction at the right time."

"We look forward to working and collaborating with local, state and federal stakeholders targeting the completion of the feasibility study".

Will Dawes, Mkango CEO commented; "We see a very significant opportunity in the US market and look forward to working with CoTec and HyProMag as we move into the next phase of growth."

"Less than 5 per cent of rare earth magnets are currently recycled from end-of-life products. Increasing recycling rates via HyProMag's HPMS technology solution to unlock this new potential source of rare earths, thereby avoiding waste to landfill and significantly reducing the carbon footprint, can make a major contribution to creating more sustainable and robust rare earth supply chains across multiple jurisdications."

HPMS technology was developed at the University of Birmingham, underpinned by approximately US$100 million of research and development funding, and has major competitive advantages versus other rare magnet recycling technologies, which are largely focused on chemical processes but do not solve the challenges of liberating magnets from end-of-life scrap streams - HPMS provides the solution.
