Approves major capacity expansion at Western Australian Iron Ore                
BHP Billiton today announced approval for the Rapid Growth Project 4 (RGP4)     
which will increase system capacity across its Western Australian iron ore      
operations to 155 million tonnes per annum (Mtpa). Initial production is        
expected to commence in the first half of CY2010.                               
BHP Billiton has approved capital expenditure of US$1.85 billion for its share  
of the project, which includes development of a new crushing and screening      
plant, as well as additional stockyards, car dumping and train loading          
facilities at Mt Whaleback. Infrastructure upgrades will also be implemented at 
satellite orebodies and the rail and port operations.                           
President BHP Billiton Iron Ore Ian Ashby said RGP4 would deliver large-scale   
benefits to the Company, its customers, employees and local communities.        
"Our high quality asset base in the Pilbara and series of staged growth projects
have helped ensure the continued delivery of outstanding returns to BHP Billiton
shareholders," he said.                                                         
"The RGP4 project will further increase the efficiency of our integrated mine,  
port and rail operations and represents a key investment in our ongoing strategy
to be more responsive to customer needs.                                        
"The project will also have substantial flow-on benefits to Pilbara communities 
through the creation of employment and business opportunities, improved         
management of valuable water resources and significantly reduced dust           
emissions."                                                                     
Mr Ashby said that a range of options to expand capacity beyond RGP4 are also   
being evaluated, subject to customer demand.                                    
"We are committed to creating further value-adding options for the business and 
providing the next phase of growth opportunities beyond our recent expansion    
projects," he said.                                                             
By the end of CY2007 BHP Billiton will have increased the capacity of its       
Western Australian iron ore operations by 60Mtpa over the past four years. This 
growth will have been achieved through a series of sequential projects,         
delivered on time and within budget.                                            
BHP Billiton`s partners in the Pilbara iron ore operations are: Itochu Minerals 
& Energy of Australia, Mitsui-Itochu Iron and Mitsui Iron Ore Corporation.
