Peñasquito

Peñasquito is one of the largest open-pit mines in Latin America, located in the state of Zacatecas, Mexico, within the Mazapil mining district, an area recognized for its high concentration of metallic resources. The operation produces gold, silver, lead, and zinc, and represents a key pillar of modern Mexican mining. The site features state-of-the-art mining and processing infrastructure, large-capacity tailings storage facilities, and advanced water management systems, designed under sustainability and environmental compliance criteria.

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:

• Engineering of monitoring and seepage collection systems: Conceptual and detailed engineering was developed for underground flow monitoring and seepage collection systems in contingency ponds, including solutions for tailings dams through collection trenches, perforated pipelines, and conveyance systems.
• Pipeline and hydraulic systems engineering: Detailed engineering was developed for the replacement, relocation, and optimization of reclaimed and fresh water pipelines, ensuring operational efficiency, reliability, and system continuity.
• Contingency pond engineering and operational optimization: Conceptual design of contingency ponds in hydrocyclone towers, aligned with international standards, optimizing storage capacity, operation, maintenance, and efficient water use.
• Cost estimation and closure planning: Validation of demolition cost studies and technical support for closure plans, ensuring technical consistency and compliance with project guidelines.
