Cerro Verde

Client: Sociedad Minera Cerro Verde SAA

Arequipa, Peru

1. Project Overview

The project was developed at the Cerro Verde mining complex, a large-scale open-pit operation dedicated to the extraction of copper and molybdenum.

The mine is located approximately 30 km from the city of Arequipa, Peru, at an elevation of 2,700 meters above sea level (m.a.s.l.).

Anddes has participated in multiple development and expansion phases of critical infrastructure, with particular emphasis on heap leach pads, process solution ponds, and surplus material deposits.

2. Project Challenges

The development and continued expansion of the Cerro Verde operation involved complex technical and operational challenges:

Construction and expansion of mining infrastructure under high-altitude conditions (2,700 m.a.s.l.).
Engineering design and implementation of heightening works for existing heap leach pads.
Ensuring physical and seismic stability of containment structures.
Optimization of site layout for new expansion phases.
Efficient hydraulic management of process solutions in leaching operations.
Upgrading and rehabilitation of aging infrastructure.
Preservation of structural integrity for critical operational facilities.
