The zone known as “Pajonales” within the Río Rayo estate has been mined by several generations of miners. Today the remaining deposits are restricted. An area was made available for the “La Obsesion” project upon the harvest of a small Acacia plantation.
In this project other aspects of modern mining were demonstrated. These included:
- Use of NZ Mobile Screen in a static position
- Deeper mining methods – 25 metres
- Protection of water courses
- Design and management of large scale sedimentation circuits
