Number     17/11                                                                
WORSLEY EFFICIENCY AND GROWTH PROJECT                                           
BHP Billiton announced today the completion of the budget and schedule review   
for the Worsley Efficiency and Growth (E&G) project.  The capital cost estimate 
for the project, encompassing the development of the Marradong mine, refinery   
expansion and connection to a multi-fuel cogeneration unit, has increased to    
US$2,995 million (BHP Billiton share).  First production is now scheduled for   
the first quarter of calendar year 2012.                                        
(1) Worsley Alumina is a joint venture between BHP Billiton (86 per cent), Japan
Alumina Associates (Australia) Pty Ltd (10 per cent) and Sojitz Alumina Pty Ltd 
(four per cent).                                                                
BHP Billiton Chief Executive Non-Ferrous, Andrew Mackenzie, said "The US$2,860  
million (100% basis), 1.1 million tonne per annum (mtpa) refinery expansion is  
being executed within the existing footprint of the facility, making it one of  
the most complex brownfield projects undertaken.  Such complexity has resulted  
in significantly lower levels of construction progress than previously          
anticipated, while broader inflationary pressures and the strengthening of the  
Australian dollar have also contributed to the cost increase.                   
"Upon completion of the Worsley E&G project, the refinery will have the capacity
to produce 4.6 mtpa of smelter grade alumina, confirming Worsley as one of the  
world`s leading alumina refineries.  We remain confident that the project will  
add value to the business over the medium to long term as it delivers low cost  
production into a fundamentally strong market."
