MKANGO AND COTEC PROVIDE UPDATE ON ROLL-OUT OF HYPROMAG'S RARE EARTH MAGNET RECYCLING TECHNOLOGY INTO THE UNITED STATES

London / Vancouver: October 10, 2023 - Mkango Resources Ltd. (AIM/TSX-V: MKA) ("Mkango") and CoTec Holdings Corp. (TSXV: CTH; OTCQB: CTHCF) ("CoTec") are pleased to provide an update on the roll-out of HyProMag's rare earth magnet recycling technology into the United States. HyProMag Ltd ("HyProMag") is a wholly owned subsidiary of Maginito Ltd ("Maginito"), which is 79.4% owned by Mkango and 20.6% owned by CoTec.

Based on positive scoping studies to date, Maginito and CoTec have commenced planning for the feasibility study for the United States operation ("Feasibility Study"), targeted for completion by mid-2024.

The proposed operating configuration for the United States operations is a modular, hub and spoke model, with the initial deployment of three Hydrogen Processing of Magnet Scrap (HPMS) recycling vessels at the spokes and a central hub comprising of rare earth (NdFeB) alloy and magnet manufacturing, subject to the outcome of the Feasibility Study.

Operating scenarios tested through the scoping studies highlighted:

· A range of production scenarios and product suites are potentially viable, including finished magnets, sintered blocks and alloy products, and incorporating up to 100% recycled NdFeB feed;

· Potential for US$50 million per year of revenue generation, based on assumed production of 500 tonnes per year of NdFeB magnets and a blended product price of US$100/kg, which is within the range of current pricing for the different products evaluated during the scoping studies;

· A target EBITDA margin of 35% to 40% would potentially be achievable under a range of scenarios, with a minimum estimated capital expenditure of US$30 million; and

· Market conditions and rare earth prices are currently subdued, indicating potential upside versus the current pricing scenario as market conditions recover, in parallel with further optimization of the development scope.

The actual results of the United States operations could vary materially depending on future pricing of rare earth elements, final product mix, agreed sales pricing for each product, capacity at which the HPMS vessels and magnet manufacturing will be operated, quality and cost of scrap feed material, primary product ratio and other material inputs. These key inputs will be further explored and optimized during the completion of the Feasibility Study.

The basis of design, product suite and operating parameters for the United States operations will be further confirmed, refined and de-risked as the recycling and magnet manufacturing facilities are commissioned and production commences at Tyseley Energy Park ("Tyseley") in the United Kingdom. First production of rare earth magnets from Tyseley is targeted for this year.

The Tyseley development is being funded by the UK Research and Innovation "Driving the Electric Revolution" challenge. HyProMag is the primary industrial user and operator of the plant, and the principal licensee for the underlying HPMS technology from the University of Birmingham.

The University of Birmingham has approved a sub-license of the HPMS technology to the HyProMag US operations, allowing Maginito and CoTec to proceed with the formation of a joint venture company. The joint venture company, HyProMag US, will be 50% held each by Maginito and CoTec, with CoTec responsible for funding all feasibility and development costs.

Julian Treger, CoTec CEO commented; "We are very pleased with the progress and the results of the scoping studies. HyProMag US continues to benefit from front-end engineering and development of the plants in the UK and Germany, which significantly de risks the US operations."

"As the planning for the Feasibility Study commences with our partner Mkango, CoTec is focused on the operational roll-out of the HyProMag technology. HyProMag's exciting recycling technology offers a long-term, sustainable and low carbon solution for the supply of domestic REE magnets. Discussions with the US Government, potential customers and recycling partners have commenced and are ongoing."

Will Dawes, Mkango CEO commented; "We are very excited about opportunities for growth in the United States and look forward to working with CoTec and HyProMag as we continue to scale-up and roll-out the HPMS rare earth magnet recycling technology. HPMS has potential to unlock the supply chain for rare earth magnet recycling and it's fantastic to see this UK developed, homegrown, innovative technology continuing to gain traction internationally."

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 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 the solution.
