The day had begun with a drive across Belo Horizonte to the Morro Velho operation Cuiaba Mine office, where the group was given a comprehensive overview of the deposits of the operation, before going underground to traverse the deposit and enclosing country rocks. This was followed by lunch at the mine canteen and then a visit to the Santa Cruz open-pit at Mina Raposas to see the oxide ore, and a brief tour of the Quieroz beneficiation plant.
