VANCOUVER, BC / ACCESS Newswire / June 30, 2026 / CoTec Holdings Corp. (TSXV:CTH)(OTCQB:CTHCF) ("CoTec" or the "Company") is pleased to announce that it has filed an independent National Instrument 43-101 technical report entitled "Mineral Resource Estimate, Preliminary Economic Assessment and NI 43-101 technical report for CoTec's Lac Jeannine Mine Tailings Reclamation and Restoration Project, Canada" dated June 24, 2026 and having an effective date of March 23, 2026 prepared by., JPL GeoServices Inc., Soutex Inc., Amerston Consulting Ltd. and Axe Valley Mining Consultants Ltd (the "PEA"). The results of the PEA were previously announced by the Company in a news release dated May 20, 2026 (the "PEA Results Release"). The Company is not aware of any new information or data that materially affects the information included in the PEA Results Release and confirms that there are no material differences in the results of the preliminary economic assessment between the PEA and the PEA Results Release.

A copy of the PEA is available under the Company's profile on SEDAR+ ( www.sedarplus.com ) and the Company's website ( www.cotec.ca ). 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 Lake 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. About CoTec CoTec is redefining the future of resource extraction and recycling.

Focused on rare earth magnets and strategic materials, CoTec integrates breakthrough technologies with strategic assets to unlock secure, sustainable, and low-cost supply chains.
