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.
