Lima, Peru – May 24, 2024 – Southern Peru Copper Corporation (SPCC), a cornerstone of Peru’s vital mining sector, has submitted a comprehensive proposal to the National Environmental Certification Service (Senace) outlining a series of critical upgrades and expansions for its Toquepala mining unit in Tacna. The ambitious plan, detailed in the Fifth Technical Sustaining Report (ITS), encompasses eight distinct modifications to operational processes and infrastructure, collectively representing a substantial investment of approximately US$471.09 million. This strategic initiative aims to bolster efficiency, extend operational life, and ensure the continued robust production of copper, a metal essential for global energy transition and technological advancement.
The Toquepala mine, a significant contributor to Peru’s economy, has demonstrated consistent performance, producing an estimated 113,700 tons of copper in the first half of 2026, with 58,400 tons in the first quarter and 55,300 tons in the second. The proposed enhancements are designed to sustain and potentially increase these output levels in the coming years, solidifying SPCC’s position as a leading copper producer.
Strategic Investments for Enhanced Capacity and Efficiency
The lion’s share of the proposed investment, a staggering US$396.5 million (84.2% of the total), is earmarked for the crucial expansion of the Quebrada Honda tailings storage facility. This significant allocation will facilitate the raising of the dam’s crest from its current elevation of 1,246.5 meters to 1,256.5 meters above sea level. This ten-meter increase is vital for expanding the facility’s storage capacity for mine tailings – the residual waste material generated during the copper extraction process. Such an expansion is paramount for ensuring the long-term viability of the Toquepala operation, providing the necessary buffer to accommodate processed material and maintain current processing rates for years to come.
Beyond the structural expansion of the tailings facility, SPCC is also dedicating approximately US$4.56 million to implement operational improvements within the Quebrada Honda site itself. These enhancements include the deployment of a dredging system in Poza 3 to effectively remove accumulated solids, thereby optimizing the facility’s operational footprint. Furthermore, the company plans to enhance the efficiency of recovered water pumping in Area 2101A and introduce a thickener system for slurries in Sector 2800. These measures are strategically designed to maximize water recovery and significantly reduce the mine’s reliance on fresh water, a critical consideration in water-scarce regions and a testament to SPCC’s commitment to sustainable water management practices.
The second largest component of the proposed investment, amounting to US$52.49 million, will be directed towards the expansion of the East waste dump. This project involves increasing the dump’s area from 484.8 hectares to 500.9 hectares, an addition of 16.1 hectares. This expansion is crucial for accommodating the growing volume of sterile material – rock and earth that does not contain economically viable quantities of copper – generated during mining operations. By increasing storage capacity, SPCC aims to optimize material handling logistics, reduce haulage distances for overburden removal, and ensure a continuous flow of ore to the processing plant.
Addressing Operational Bottlenecks and Improving Worker Conditions
The remaining proposed interventions, while individually smaller in financial scope, are equally vital in addressing operational bottlenecks and enhancing the overall efficiency and safety of the Toquepala operation. A total of US$5.61 million will be invested in constructing a covered storage area for spare components, ensuring their protection from environmental degradation and facilitating easier access.
