comprising BHP Billiton/SONATRACH)                                              
The ROD Integrated Development consists of the development of six satellite     
oilfields in the Berkine Basin in eastern Algeria. The project will produce     
80,000 barrels of Sahara Blend crude oil per day, with associated gas being     
reinjected into the reservoir together with water to provide pressure support to
the reservoir.  The development drilling has been concluded and a total of 34   
development wells are currently available for production operations.  As at the 
end of June over 6.75 million workhours have been completed at the construction 
site without a Lost Time Incident. Overall project progress is 93 per cent      
complete. Lower than planned productivity at the construction site has impacted 
progress and first oil is now scheduled for fourth quarter 2004.  The project is
expected to be delivered within the original budget.  BHP Billiton`s share is   
US$192 million.

The development of the Escondida Norte pit, located approximately 5 kilometres  
north of the existing Escondida mining operations, was approved in June 2003.   
Pre-mine waste stripping continued during the quarter, using both contractor and
Escondida equipment, with a third truck-shovel fleet commencing during June     
2004. Total material movement in the pre-mine to the end of June 2004 was 47.9  
million tonnes.  Construction development during the period involved the partial
erection of the mine fleet maintenance work shop, commencement of the crusher   
foundation area and its associated retaining wall, partial construction of the  
overland conveyor alignment and near completion of the light vehicle access     
road.  Pre-mine development, design and construction activities are currently on
track to meet first ore delivery to the crusher in the fourth quarter of 2005.  
Development costs are estimated at US$400 million (BHP Billiton share US$230    
million).

The Dendrobium Mine will be a low cost underground longwall operation capable of
producing 5.2 Mtpa of raw coal (3.6 Mtpa of clean coal).  Board approved capital
expenditure is US$170 million.  Construction activities associated with the mine
surface facilities, ventilation shaft, washery upgrade and Kemira Valley Rail   
Coal Loading facilities have been completed and successfully commissioned.      
Construction activities associated with the thermal drier are well underway.    
The majority of the project`s remaining work is related to the underground      
drivage required to install and commission the longwall.  All mining units have 
passed through the zone where difficult mining conditions had been experienced  
during the last quarter and are producing at expected rates.  A review of       
project costs is currently underway.  We continue to expect longwall            
commencement in the middle of 2005.

MINERALS EXPLORATION                                                            
The minerals exploration group of BHP Billiton continued to pursue global       
exploration opportunities for key commodities of interest to the group utilising
both the Junior Alliance Program and in-house capabilities.                     
The bulk sampling programme on the BHP Billiton Qilalugaq property near Repulse 
Bay, Nunavut, Canada (BHP Billiton 100%), has been completed. Processing of the 
sample is underway. Diamond drill testing of previously defined targets         
commenced on time and is on-going. Till sampling, Falcon and Dighem airborne    
surveys are underway on the remainder of the property to define additional      
targets.                                                                        
EXPLORATION EXPENDITURE
