The mine is located in the Antamina Creek, in the district of San Marcos, Ancash and has an estimated useful life until 2029. Total reserves amount to 745 million metric tons. The mineral deposit is of type skarn of copper-zinc, silver, molybdenum and bismuth and, at present, it is considered the largest in the world.

Anddes contributes to the success of the Antamina project, through:

• Limestone monitoring and geological-geotechnical mapping.
• Analysis of deformations of the pipeline and the water pipe.
• Study and geotechnical analysis of the new line of the pipeline. Analysis of deformations of the pipeline was carried out.
• Analysis of deformations of the pipeline and water pipe for protection in the area of the East Dump.
• Geotechnical study for the Production Optimization Project. Includes field research and geotechnical analysis in PPL, Yanacancha and mine.
• Pre-feasibility design of the access road to the tailings dam.
• Geotechnical study for the foundation of the point E platform.
• Study of soil mechanics for the foundation of concentrate storage tanks.
• Detailed engineering for the construction of the Punto E platform, to be built with clearing and over-sized material from the crushing process.
• Geophysical prospecting using 13 120 m seismic refraction lines and 6 MASW test points of Project 16062 polishing pond dam bypass tunnel. Development of seismic geophysical tests (refraction, MASW and MAM) and electrical (electrical tomography) for three areas of the Yanacancha – Conococha – Chaquitambo road located at km 106 of route 16 and at km 28 and km 65 of route 111.
