Since October 2009, Xstrata Copper has approved the development of five brownfield projects (Lomas Bayas II, Ernest Henry underground, Antamina expansion, Collahuasi expansion and Tintaya-Antapaccay) and one greenfield project (Las Bambas). Here we publish photographs of the construction progress at Tintaya-Antapaccay and Las Bambas in southern Peru, Lomas Bayas II, in northern Chile, and the Underground mine and Magnetite Plant project at Ernest Henry mine in North Queensland, Australia. Photo libraries for other Xstrata Copper's development projects are under construction.
