概述：力拓向西澳大利亚Pilbara铁矿石项目追加8.65亿美元的投资，总投资额达到10亿
Rio's billion-dollar expansion plans
Rio Tinto is set to invest a further $865 million to expand its Pilbara iron ore operations in Western Australia, bringing total investment for the expansion to more than $1 billion.
The company is aiming to boost capacity at its Pilbara operations to 330 million tonnes a year.
Rio announced last month that it planned to spend more than $200 million in dredging works at the Cape Lambert port to more than double its iron ore capacity by 2016.
The latest funding announcement is for the construction of a new wharf and the procurement of items such as pile and marine structures, on-shore earthworks and machines.
Construction is dependent on several government and other approvals.
