Antamina

Client: Compañía Minera Antamina S.A.

Áncash, Peru

The Antamina mining unit is located in the ravine of the same name, in the district of San Marcos, Ancash region, Peru. This operation has an estimated mine life through 2029, with total reserves amounting to 745 million metric tons. The deposit is a copper-zinc skarn type, with the presence of silver, molybdenum, and bismuth, and is currently recognized as the largest deposit of its kind in the world.

In this context, a series of specialized services and studies were developed, aimed at ensuring the safety, efficiency, and sustainability of the operation, as detailed below:

  • Execution of geotechnical investigations through test pits, geological-geotechnical mapping, and laboratory testing to characterize foundation soils, platforms, and waste dumps.
  • Development of geotechnical studies for mining infrastructure such as fuel stations, plants, leach pads, access roads, and camps, including stability and bearing capacity analyses.
  • Assessment of stability and deformation in slurry pipelines and associated structures, ensuring their operational integrity.
  • Analysis and optimization of waste dumps through deformation, infiltration, and water management studies to improve performance and safety.
  • Application of geophysical studies (seismic refraction, MASW, and electrical resistivity tomography) for subsurface characterization in linear projects and operational areas.
  • Design and evaluation of critical infrastructure such as tailings dams and platforms, including liquefaction analysis and pre-feasibility studies.
  • Soil evaluation for roads, access routes, and weighing systems, ensuring suitable conditions for operation and transportation.
  • Consulting services in geotechnical and hydrogeological drilling, integrating field and laboratory data for decision-making.
