HYPROMAG USA COMMENCES STOCKPILING OF FEEDSTOCK

London / Vancouver: August 26, 2025 - CoTec Holdings Corp. (TSXV: CTH; OTCQB: CTHCF) ("CoTec")  and Mkango Resources Ltd. (AIM/TSX-V: MKA) ("Mkango") are pleased to announce that Intelligent Lifecycle Solutions LLC ("ILS") has formally commenced its stockpiling of feedstock initiative pursuant to the recently announced feedstock supply and pre-processing site share agreement between HyProMag USA LLC ("HyProMag USA" or the "Project") and ILS. Pre-processing of the feedstock is expected to commence prior to December 31, 2025.

The stockpiling and pre-processing will take place at both the ILS sites in Williston, South Carolina and Reno, Nevada (the "ILS sites"). ILS is a global electronics recycling company processing electronic waste. It is a full-service IT asset disposition, electronics recycling and scrap purchasing company and is fully compliant in ISO 14001:2015, ISO 45001:2018 and "Responsible Recycling R2v3 Recycler" at its USA locations. Through ILS, HyProMag USA will provide full traceability on its products to support the "closed loop" circular economy and critical mineral supply chains within the United States.

Julian Treger, CoTec CEO commented: "This is another major milestone in the execution of the HyProMag USA project. Securing feedstock is key to the success of any recycling business and we are pleased to work with credible companies such as ILS. HyProMag USA's target is to secure between 6 months and 12 months of feedstock prior to commissioning of HyProMag USA's advanced stage rare earth magnet recycling and manufacturing plant to be located in Dallas-Fort Worth, Texas. HyProMag USA aims to become a major contributor to the USA supply chain of rare earth magnets, a critical input for accelerating the reshoring of the U.S industrial base."

Will Dawes, Mkango CEO commented: "The agreement with ILS and commencement of stockpiling of NdFeB feedstock underpins the rapid deployment of Hydrogen Processing of Magnet Scrap (HPMS) and associated magnet manufacturing into the United States by HyProMag USA, with detailed engineering well underway following the positive feasibility study last year. These developments will catalyse development of a more robust rare earth supply chain, whilst unlocking new NdFeB scrap sources in the United States and generating significant value for HyProMag USA and its stakeholders."
