CoTec Completes Infill and Expansion Resource Drilling Programme at the Lac Jeannine Project, Engages Corem for Metallurgical Testing and Commences a Process To Appoint an EPCM Provider for the Feasibility Study

VANCOUVER, BC / ACCESS Newswire / August 28, 2025 / CoTec Holdings Corp. (TSXV:CTH)(OTCQB:CTHCF) (“CoTec” or the “Company”) is pleased to announce the completion of its 2025 sonic drilling and bulk sampling testing programme at the Lac Jeannine Iron Tailings Project, Québec, Canada (“Lac Jeannine”, or the “Project”). The Company has engaged Corem to complete the metallurgical testing and has commenced a process to appoint a EPCM provider for the Feasibility Study. The Feasibility Study is expected to commence in Q3, 2025.

Julian Treger, CoTec CEO commented; “CoTec has progressed its discussions with strategic partners to move rapidly onto preparation of a Feasibility Study with the support of all stakeholders, including the Government of Québec, First Nations and other interested parties. The results from this next phase of drilling and bulk sample collection will allow CoTec to increase its current resource estimate for Lac Jeannine and potentially unlock additional material outside of the tailings dam to reprocess.

The Company is very excited to commence a Feasibility Study regarding the recovery and production of critical mineral iron ore concentrate at competitive cost structures which can deliver high purity iron concentrates for the green steel industry. The Lac Jeannine Project offers great potential for the resource industry to recover the economic benefit of large Fe tailing sites.”

In June 2024 CoTec announced the completion of an initial Mineral Resource Estimate (the “MRE”) and positive Preliminary Economic Assessment (“PEA”) for the Project^[i]. Based on open-pit extraction methods and the production of a gravity concentrate via conventional processing techniques and at a discount rate of 7.0% (and based solely on the MRE), the pre-tax NPV is US$93.6M, and its IRR is 38%, and the after tax NPV is US$59.5M, and its IRR is 30%. As part of the Feasibility Study, the Company is including the application of the Salter Cyclone Multi-Gravity Separators (“MGS”) technology for the recovery of additional iron ore from the Project.

The completed drilling targeted upgrading the existing Inferred Mineral Resource of 73 million tonnes (Mt) at 6.7% total Fe for 4.9 Mt of contained total Fe to Indicated and to extend the Project to a larger portion of the Adjacent Tailings. The inclusion of the Adjacent Tailings has the potential to almost double the life of mine with no additional capex unlocking substantial upside potential.

Drilling Highlights

• An infill and expansion programme totalling 572 meters of sonic drilling for 12 holes, drilled up to 58 meters, was completed on the historical tailings of the previous Lac Jeannine iron ore mine operated by the Québec Cartier Mining Company between 1959 and 1985.

• Additional bulk sampling has also been concluded, a total of 7 tonnes of tailings and waste rock dumps were recovered to assess their iron content and has been shipped to Corem’s testing facility in Québec.

• Bulk sampling and assay results are expected in Q4 2025.
