HyProMag USA Commences Process to Appoint EPCM Provider for Rare Earth Magnet Recycling and Manufacturing Project

LONDON, December 5, 2024 - CoTec Holdings Corp. (TSXV:CTH)(OTCQB:CTHCF) ("CoTec") and Mkango Resources Ltd. (AIM/TSX-V: MKA) ("Mkango") are pleased to announce the initiation of a "Request for Proposal" process from leading Engineering, Procurement and Construction Management ("EPCM") providers to complete the detailed engineering design, procurement and construction management phase for HyProMag USA LLC. ("HyProMag USA") state-of-the-art rare earth magnet recycling and manufacturing project in the United States (the "Project").

The results of the positive feasibility study for the Project were announced on November 25, 2024, which can be accessed via the following link: https://hypromagusa.com/hypromag-usa-feasibility-study-demonstrates-robust-economics-and-the-opportunity-to-develop-a-major-new-domestic-source-of-recycled-rare-earths-magnets-for-the-united-states/

The detailed engineering design phase will include the completion of sufficient engineering design works to support development of the AACE¹ Class 1 capital cost estimate to update that of the Feasibility Study. This will also support the final site selection efforts which are to be completed in H1 2025 and allow the commencement of site permitting in line with the initial project schedule. This targets initial revenue in Q1 2027.

Following completion of the detailed engineering design phase, a decision is expected to be taken mid-2025 as to whether HyProMag USA will proceed with the final procurement and construction of the Project (the "Notice to Proceed ").

Julian Treger, CoTec CEO commented: "Following the successful completion of the independent Feasibility Study,we are looking forward to working with leading EPCM providers to build these facilities. The detailed engineering design phase is expected to deliver further cost savings and design improvements which should enhance the Project's metrics. The company is now focused on working with its stakeholders and potential partners in securing funding from the U.S. Government, financing, off-take and feed supply. The end-to-end process of recycling end-of-life NdFeB magnets into new sintered NdFeB magnets is supported by the Minerals Security Partnership² which aims to accelerate the development of secure, diverse, and sustainable supply chains for critical minerals."

Will Dawes, Mkango CEO commented:"Momentum continues on the Project following the positive results from the feasibility study announced last week, and we are very excited to be pushing forward with the EPCM selection process. This important Project will help catalyze further development of a robust domestic ecosystem for rare earth magnet recycling and manufacturing in the United States, and will be underpinned by rigorous design and engineering standards. We look forward to working with the Project team as we move to the next stage of development."

Ownership

HyProMag is 100 per cent owned by Maginito Limited ("Maginito"), which is owned on a 79.4/20.6 per cent basis by Mkango and CoTec. HyProMag USA is owned 50:50 by CoTec and Maginito.

About HyProMag

HyProMag is commercializing the patented Hydrogen Processing of Magnet Scrap ("HPMS") recycling technology in the UK, Germany and United States. HyProMag is also evaluating other jurisdictions, and in mid-2024 launched a collaboration with Envipro on rare earth magnet recycling in Japan. HPMS technology was developed at the Magnetic Materials Group (MMG) at University of Birmingham, underpinned by approximately US$100 million of research and development funding, and has major competitive advantages versus other rare earth 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.

The MMG is internationally recognized for its work on the circular economy of rare earth magnets. The group has made major contributions to research and industrial application of hydrogen for processing of magnets. Professor Emeritus Harris pioneered the initial work on hydrogen decrepitation (HD), currently used worldwide to produce magnets, and co-authored the 1986 paper on the world's first hydrogen based sintered magnet. Today, almost all NdFeB magnet production and recycling methods take advantage of the HD process.

The HPMS process recovers neodymium iron boron ("NdFeB") permanent magnets from end-of-life scrap streams in the form of a demagnetized NdFeB metallized alloy powder for remanufacture into recycled NdFeB magnets with a significantly reduced carbon footprint, and has major competitive advantages versus other magnet recycling methods using chemical processes.
