In 2022, Cerro Verde Mining Company requested BRASS to develop a feasibility engineering study with the main objective to obtain the most viable design with respect to technical, economic, maintenance, operations and permit considerations related the overall scope of management, distribution and transportation of tailings and wastewater located at the Linga DR Tailings Deposit This feasibility study considered a 57m rise in the deposit’s elevation compared to the current approved wall height. The development of the project took into account previous considerations outlined in the study “Evaluation of Future Tailings Storage Capacity Alternatives at Cerro Verde” that had previously been carried out by third parties.
