Cuajone

Cuajone is an open-pit copper mine located in southern Peru, 30 kilometers from the city of Moquegua and 840 kilometers from Lima. This operation represents one of the country’s main sources of copper production, with mining and processing infrastructure that requires specialized technical solutions to ensure its continuous development.

In this context, a series of specialized services and studies were carried out to ensure the safety, efficiency, and sustainability of the operation, as detailed below:

• Geotechnical studies for mining infrastructure: Development of geotechnical studies for haul roads, leach pads, and operational areas, with a focus on stability and settlement analysis.
• Leach pad stability assessment: Evaluation of the physical stability of leach pads at different stages, considering operating conditions, expansions, and closure scenarios.
• Seismic analysis and slope stability: Update of seismic hazard analyses and evaluation of slope stability under both static and dynamic conditions.
• Geotechnical and geomechanical investigations: Investigations through field and laboratory testing, including CPTu, piezometers, and specialized tests.
• Waste dump evaluation: Stability assessment of waste rock dumps under both operational and projected conditions, ensuring safe performance.
• Comprehensive hydrogeological studies: Development of hydrogeological studies, including rock mass characterization, conceptual and numerical modeling, and water balance analysis.
• Optimization of geotechnical designs: Update and optimization of geotechnical designs for leach pads and associated components, maximizing capacity and operational efficiency.
• Detailed engineering for leach pads: Preparation of detailed engineering for the construction of leach pads and associated works, integrating technical and operational criteria.
