Antapaccay

Antapaccay is located in southern Peru, in the Cusco region, Espinar province, at an approximate altitude of 4,100 meters above sea level. It is an open-pit copper mining operation with a modern sulfide concentrator plant, dedicated to the production of copper concentrates with gold and silver as by-products. Operations began in November 2012, and it is considered one of the main mining units in the region. It is currently operated by Glencore through Compañía Minera Antapaccay.

In this context, a range 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 operations: development and updating of geotechnical studies, including field support, stability analysis, and evaluation of foundation conditions.
• Tailings dam engineering: development and updating of engineering at conceptual, basic, and detailed stages, including aspects such as impermeabilization, dam raising, and tailings disposal.
• Seismic hazard assessment: seismic hazard analysis and dynamic evaluations for critical infrastructure, considering current regulations and site conditions.
• Geotechnical engineering for mining infrastructure: studies for thickeners, conveyor belts, crushers, and platforms, ensuring their stability and performance.
• Geophysical characterization and seismic response: studies for subsurface characterization and seismic response analysis of key components.
• Geotechnical monitoring and instrumentation: implementation and monitoring of instrumentation systems, evaluation of deformations, and operational behavior.
• Material evaluation and waste dump stability: waste rock characterization, geomechanical analysis, and stability assessment of dumps and open pits.
• Comprehensive technical consulting: drilling supervision campaigns, engineering updates, RFI responses, technical guidelines, and support during construction stages.
