VANCOUVER, BRITISH COLUMBIA / ACCESS Newswire / November 26, 2025 / CoTec Holdings Corp. (TSXV:CTH)(OTCQB:CTHCF) ("CoTec" or the "Company") is pleased to note that its ~16.5% investment, MagIron LLC ("MagIron"), today announced the successful completion of its comprehensive independent pilot plant test work program conducted in partnership with the University of Minnesota, Natural Resources Research Institute ("NRRI") at Coleraine, Minnesota. The test work forms a key component of MagIron's ongoing feasibility study for the restart of Plant 4 in Grand Rapids, Minnesota.

The independent pilot-scale program has confirmed the technical viability of MagIron's new and innovative process flowsheet and demonstrates exceptional iron recovery rates and concentrate quality, consistent with previous bench-scale results conducted since 2022. The flotation pilot plant, while making direct reduction ("DR") grade concentrate of 68.3% total Fe (post-LOI), achieved an 83.5% iron recovery. Meanwhile, the flotation pilot plant, while making blast furnace ("BF") grade concentrate of 66.4% total Fe (post-LOI), achieved an iron recovery of 85.9%. The original Plant 4 previously produced BF grade concentrate at an iron recovery of 40.0%. On a comparable basis, the new Plant 4 flow sheet iron recovery is slightly more than double that of the prior facility. These results validate MagIron's ability to produce DR-grade iron oxide concentrate, supporting the Company's strategy to supply high-grade feedstock for the growing Electric Arc Furnace ("EAF") steel sector.

Data from the pilot plant and bench testing campaign forms the foundation of the forthcoming National Instrument 43-101 ("NI 43-101") compliant Mineral Resource and Reserve estimate and will be incorporated into the independent feasibility study being completed by Behre Dolbear, which is expected to be finalised shortly.

Julian Treger, CEO of CoTec commented: "The completion of the pilot plant study and its exciting results are a major step forward for MagIron towards the execution of its strategy to re-start these assets. We remain very bullish on MagIron and are confident that they could become a major player in the US steel industry. As a large shareholder, MagIron's success will further improve the substantial value proposition of CoTec."

Larry Lehtinen, CEO of MagIron, commented: "The successful completion of our bench testing and pilot plant programs marks another major milestone in the restart of Plant 4. The results confirm that MagIron's new process, has the potential to deliver outstanding recovery and product quality metrics. These findings reinforce the robustness of our flowsheet and provide critical validation as we advance our feasibility study and prepare to publish our NI 43-101 compliant resource and reserve statement in the coming weeks."
