Tierra Group completed a collection of geomechanical field data (Inspections, mappings, sampling, testing, among others) for the tunnels, plant-mine road, areas at the base of the dump, access to tailings dam, truck shop slopes, bypass, and non-permanent accesses. The works also included data processing, engineering analyses, such as slope stability analysis and kinematic analysis, and geotechnical monitoring of areas of interest.

In addition to this, geotechnical support was provided for the construction of the tunnels, supervision of the different mine structures in Area 2000, supervision of main access road, and general administration of the project.
