The group were given a very comprehensive visit including presentations, pit visit and core inspection of representative drill holes. They then returned to Iquique in the evening to spend the night.
The following day was more relaxing, beginning with a late start and a drive to Calama of around 5 hours to arrive in the mid-afternoon.
On Thursday 27 April, the group was given an overview of the Chuquicamata open pit, which is ~10 km north of Calama, and an opportunity to study the geology, alteration and mineralisation of the Codelco Chuquicamata mine in drill core.
