Attached please find a press release on: The Xstrata plc Board has approved an investment of US$1.47 billion to develop the Antapaccay copper project as a major long-life, low cost brownfield expansion to the Tintaya copper mine in southern Peru. The Peruvian authorities have recently approved the project's Environmental and Social Impact Study.
