Lac Jeannine Mine produces 67% FeT iron concentrate

VANCOUVER, BC / ACCESS Newswire / July 29, 2026 / CoTec Holdings Corp. (TSXV:CTH)(OTCQX:CTHCF) ("CoTec" or the "Company") is pleased to announce that recent metallurgical test work for the Lac Jeannine Mine Tailings Reclamation and Restoration Project (the "Project") has proven the ability of the Project to produce a high-purity iron concentrate grading in excess of 67% FeT and low in impurities. The 67% FeT concentrate represents an important technical milestone that supports the Project's positioning as a high-purity iron project aligned with Québec's critical and strategic minerals framework and Canada's Critical Minerals List, subject to completion of the ongoing Feasibility Study for the Project.

To be considered in the list of Québec's critical and strategic minerals as high-purity iron, iron concentrate must contain at least 67% iron and be low in impurities. i Similarly, Canada's Critical Minerals List was updated in 2024 to include high-purity iron in its list of critical minerals. ii

Julian Treger, CEO of CoTec, commented : " The 67% FeT concientrate is another major milestone for the Project. It validates the quality of the resource, the effectiveness of our processing strategy and our vision of transforming a historic environmental liability into a strategic asset capable of supporting the global transition to lower-carbon steel production."

The 2026 Mineral Resource Estimate and Preliminary Economic Assessment (the "Project PEA") iii demonstrated the project's economic potential and confirmed its ability to produce a high-purity iron concentrate grading approximately 66.8% Fe iv . Subsequent engineering and metallurgical optimisation programs through BBA have now validated pathways to producing a 67% FeT concentrate, low in silica and alumina and other deleterious elements.

Recent metallurgical test work conducted at Corem using bulk sample material (collected in 2023 v ) confirmed the production of high purity iron concentrate, in excess of 67% FeT. This test work is part of the ongoing Feasibility Study which remains subject to completion and disclosure in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"). Achieving this grade of concentrate is a critical milestone that significantly enhances the project's strategic importance. As global steel producers continue to seek higher-grade feedstocks capable of reducing carbon emissions and improving blast furnace and DRI efficiencies, the confirmed concentrate quality supports the Project's potential to align with the technical requirements supporting the industry's transition to lower-carbon steel production methods.

With feasibility work continuing, environmental baseline studies underway and engagement progressing with Indigenous communities and government stakeholders, the Project is steadily advancing toward its next development phase. The Project PEA indicates an after-tax net present value of US$91.9 million and an internal rate of return of 29.6% over a projected 15-year mine life, with additional upside from further resource expansion and process optimisation.

The Lac Jeannine Mine Tailings Reclamation and Restoration Project

The Lac Jeannine property comprises a contiguous block of thirty-one (31) mineral claims covering an aggregate of 1,649.34 hectares (ha) in the Caniapiscau regional county municipality (RCM) of the Côte-Nord Region of eastern Québec, approximately eight kilometres (km) southeast of the abandoned town-site of Gagnon and 290 km north of the City of Baie-Comeau. The property is located on the traditional territory of the Innu of Pessamit.

The Project encompasses the former Lac Jeannine open pit mine, from which approximately 260 million long tons of ore at 33% iron, in mainly specular hematite form, was extracted between 1961 to 1976. The Property also covers the "Tailings Storage Facility" (TSF), the area where the tailings from the on-site ore concentrator were deposited but not reclaimed. In 1984, the Lac Jeannine mining and processing facilities were shut down.

The Lac Jeannine mine site is identified by Québec's Ministry of Natural Resources and Forests (MRNF) as the largest abandoned mining site under government responsibility. CoTec's focus is on the tailing's material, planned to be re-processed for residual iron, and rehabilitate the TSF to as close to its natural state as possible.

This press release is based on metallurgical investigations and project review activities conducted by BBA Inc. in support of the Project as disclosed by CoTec and should be read in conjunction with the Project PEA.
