Hydrogeological and geochemical evaluation associated with the Phase III expansion

Hydrogeological and geochemical studies to support the EIA for the expansion of Collahuasi Phase III. The following activities were carried out:

  • Establish the hydrogeochemical baseline of the sites for the new dumps.
  • Evaluate environmental impacts in terms of potential DAR generation of dumps.
  • Define a plan for monitoring and controlling the potential impacts of dumps.
  • Refining program for geochemical and hydrogeological characterization of dumps and cracks.
  • Numerical models to determine flow rates and drainage qualities of dumps and pits and their impact on the environment.
