COTEC AND MKANGO APPOINT LEAD ENGINEERS PEGASUSTSI AND BBA

TO PERFORM ENGINEERING, PROCUREMENT AND CONSTRUCTION MANAGEMENT (EPCM) SERVICES FOR HYPROMAG USA TO PRODUCE RARE EARTH MAGNETS IN THE U.S.

London / Vancouver: April 22, 2025 - CoTec Holdings Corp. (TSXV: CTH; OTCQB: CTHCF) ("CoTec") and Mkango Resources Ltd. (AIM/TSX-V: MKA) ("Mkango") are pleased to announce that U.S.-based PegasusTSI Inc. ("PegasusTSI") and Canada-based BBA USA Inc. ("BBA") have been engaged to complete the HyProMag USA, LLC ("HyProMag USA") engineering, procurement and construction management ("EPCM") services for HyProMag USA's advanced stage rare earth magnet recycling and manufacturing project located in Dallas-Fort Worth, Texas (the "DFW Hub"). The award of the EPCM contract follows the November 2024 completion of the base case Feasibility Study for HyProMag USA[i] ("Feasibility Study"), which indicated a NPV_7% of US$262 million based on current market prices and US$503 million based on forecast prices.

The project will be executed over a 24-month period with the work being undertaken from the PegasusTSI Tampa office, supported by an owner's team comprised of HyProMag Limited, CoTec and Mkango.

First revenue is targeted in H1 2027 following a Notice to Proceed ("NTP") expected in H2 2025 following completion of the detailed engineering design and value engineering phase. HyProMag USA is initially targeting to supply 10% of U.S. domestic demand[ii] for NdFeB magnets within five years of commissioning the first DFW Hub. 

Julian Treger, CoTec CEO commented: "The EPCM represents a significant milestone towards the construction of commercial-scale magnet recycling and production facilities, reshoring U.S. manufacturing capability and reducing dependence on foreign magnets and rare earths. Following the competitive bid process, we are looking forward to continuing to work closely with BBA and PegasusTSI to develop these facilities. As HyProMag USA progresses it will be working and collaborating with local, state and federal stakeholders. HyProMag USA is supported by the Minerals Security Partnership,[iii] which aims to accelerate the development of diverse critical minerals supply chains in cooperation with industry and other governments to support strategic projects."

Will Dawes, Mkango CEO commented: "We are very excited to see HyProMag USA's groundbreaking rare earth magnet recycling and manufacturing project proceed to the next stage of development. This project will make a major contribution to the creation of a more robust rare earth supply chain and a strong platform for further expansion in North America, complementing the ongoing HyProMag developments in the UK and Germany.  

The detailed engineering design and value engineering phase will include the completion of sufficient engineering design works to support development of the AACE Class 2 capital cost estimate to update what was outlined in 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. Environment and permitting studies will be supported by U.S.-based Weston Solutions, Inc.

During this phase and prior to the NTP, HyProMag USA will aim to secure commercial arrangements with potential feed supply and product off-takers to meet ongoing financing obligations. Discussions with federal, state and municipal governments continue to progress. HyProMag USA has the potential to supply the United States with sustainable, long term domestic supply of neodymium/iron/boron (NdFeB) permanent magnets to enable the creation of secure, low carbon and traceable rare-earth supply chains.

The Feasibility Study includes the DFW Hub, and two pre-processing facilities located in South Carolina and Nevada respectively. In March 2025, HyProMag USA announced the expansion of the detailed engineering phase to include three HPMS vessels[iv] and that it was initiating concept studies for further expansion and complementary "Long Loop" recycling[v]. The DFW Hub's annual production is expected to be 750 metric tons per annum of recycled sintered NdFeB magnets and 807 metric tons per annum of associated NdFeB co-products (total payable capacity - 1,557 metric tons NdFeB within five years of commissioning) over a 40-year operating life. It is expected the production facility will provide significant optionality to supply the U.S. market with additional NdFeB alloy powder while assisting in revitalising the U.S. magnet sector with the creation of 90-100 skilled magnet manufacturing jobs.

Also in March 2025, HyProMag USA announced the results of an independent ISO-Compliant product carbon footprint study which confirmed an exceptionally low CO₂ footprint of 2.35 kg CO₂ eq. per kg of NdFeB cut sintered block product.[vi]

Ownership

HyProMag USA is owned 50:50 by CoTec and HyProMag Limited. HyProMag Limited 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.

About HyProMag

HyProMag is commercializing Hydrogen Processing of Magnet Scrap (HPMS) recycling technology in the UK, Germany and the United States. 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 - HPMS provides this solution.
