PETROLEUM DEVELOPMENT                                                           
Atlantis Development, Gulf of Mexico, USA (BHP Billiton 44%, non-operated)      
BHP Billiton completed full capital allocation for the Atlantis project in      
February 2003.  Our share of total project expenditure is US$1.1 billion.       
During the quarter, fabrication of the facilities topsides started at           
McDermott"s shipyard in Louisiana.  The project remains on budget and on        
schedule for first production in the third quarter of 2006.                     
OHANET Development, Algeria (BHP Billiton 45%, joint operating organisation     
comprising BHP Billiton/SONATRACH)                                              
The OHANET Development consists of the development of four gas-condensate       
reservoirs in the Illizi Basin in southern Algeria. The project will provide a  
gas treatment facility with a capacity of 20 million standard cubic metres per  
day fed by 47 production wells, of which 32 will be new and 15 will be re-      
completions of existing oil producers.  3D seismic data across all reservoirs   
has been processed and incorporated into the reservoir models.  By the end of   
June 2003 a total of 28 new wells had been drilled and completed and 15 existing
wells had been re-completed.  The last four wells have been deferred to allow   
three to four years of production history to be gathered.  Construction is      
essentially complete and the plant is undergoing commissioning and testing      
before being brought into production.  First production is scheduled for the    
third quarter of 2003, and BHP Billiton"s share of capital expenditure is US$464
million.                                                                        
Mad Dog Development, Gulf of Mexico, USA  (BHP Billiton 23.9%, non-operated)    
BHP Billiton announced its sanction of the Mad Dog field, approving up to US$335
million for development of the Gulf of Mexico oil and gas field. Construction is
progressing on the hull (in Finland) and topsides (in the USA), with an         
estimated 50 per cent of the work complete at the end of June 2003.  Drilling   
was completed on the four pre-drill development wells during the quarter.  The  
project is on budget, and first production remains on schedule for the end of   
calendar year 2004.

In March 2003, BHP Billiton announced sanction of the first development phase of
the Greater Angostura oil and gas field off the northeast coast of Trinidad.    
Phase one of the development involves engineering, construction and installation
of production and transportation facilities required to recover the oil reserves
of the field.  The partners have also approved the project.  During the quarter,
site work began on the onshore oil storage terminal.  Evaluation, negotiation   
and award of contracts for fabrication and construction work continues, as well 
as planning and other preparations for the facilities, subsea, transportation   
and other aspects of this project.   BHP Billiton"s share of capital expenditure
for the first phase is expected to be around US$327 million.  First oil is      
scheduled for the end of calendar year 2004.

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. 36 development wells will be required, 10 of which will be       
recompletions of already drilled wells. At the end of June 2003, 17 new         
development wells had been completed and the 18th was nearing completion.       
Procurement of all major equipment is complete.  Erection of the piperack       
steelwork is well advanced and tank farm construction is underway.  Overall     
project progress is 61 per cent complete.  First production is scheduled for the
end of first quarter 2004 and BHP Billiton"s share of capital expenditure is    
US$192 million.                                                                 
Minerva (BHP Billiton 90%, operated)                                            
Work is progressing under a Lump Sum Turn Key contract awarded to a joint       
venture comprising McConnell Dowell Constructors (Australia) and Saipem         
(Portugal) for engineering and construction of the pipeline and gas plant       
facilities.  The offshore drilling and completion of the two new subsea wells   
has been successfully completed and civil engineering works are progressing on  
the gas plant site near Port Campbell.  Work is continuing on the horizontally  
directionally drilled pipeline shore crossing, and the onshore pipeline is now  
largely complete.  The installation of the offshore pipeline is scheduled for   
the fourth quarter of 2003.  The project remains on budget (BHP Billiton"s share
of capital expenditure is US$123 million).  Some delays have been experienced   
against the project"s original schedule, where first gas production was expected
in the first quarter of 2004.

BHP Billiton acquired a 25 per cent interest in the Caesar oil pipeline and a 22
per cent interest in the Cleopatra gas pipeline which will transport product    
from the Mad Dog and Atlantis fields to pipelines closer to shore.  The         
shallower portions of the deepwater pipe lay have been completed, with the pipe 
to a third party facility and the spur to Mad Dog set during the quarter.       
Installation of the deeper water section of the pipe is in progress.  The       
project is on budget (BHP Billiton"s share of the capital cost is estimated at  
US$100 million) and on schedule to commence operation coinciding with first     
production from the third party facilities in advance of first hydrocarbon      
production from Mad Dog and Atlantis.                                           
Zamzama Field Development, Pakistan (BHP Billiton 38.5%, operated)              
Phase 1 of the development of the Zamzama Gas Field is complete.  The new plant 
has been commissioned approximately four months ahead of schedule.  The gas     
plant is operating to specification and gas is being delivered to customers as  
per the contractual arrangements.  Three new wells, Zamzama-3, Zamzama-4 and    
Zamzama-5 were drilled during this phase and these are tied into two new 140    
MMcf/d processing trains.  A fourth well, Zamzama North, designed to further    
appraise the field is nearing completion.  BHP Billiton"s share of total project
capital expenditure is US$40 million, and final costs are expected to be under  
budget.

expected towards the end of the first quarter 2004.  Expenditure to date remains
in line with the budgeted US$449 million.                                       
Base Metals                                                                     
Escondida Norte, Chile (BHP Billiton 57.5%)                                     
The development of the Escondida Norte pit, located approximately 5 kilometres  
north of the existing Escondida mining operations, was approved in June 2003 as 
part of Escondida"s operating strategy to maintain copper production capacity in
future years.  The development will include pre-stripping of overburden, and the
construction of infrastructure to support mining and crushing/conveying of the  
ore to the existing Escondida processing plants, which will also continue to    
receive ore from the existing mine.   Combined proved and probable reserves of  
sulphide ore are estimated at 502 million tonnes of sulphide ore at an average  
copper grade of 1.44%, and a cut off grade of 0.7%, giving an ore reserve life  
of approximately 17 years.  Ore reserves have been revised since last published 
in our news release of 16 June 2003, where proved and probable reserves were    
estimated at 526 million tonnes of sulphide ore at an average copper grade of   
1.42% and a cut off grade of 0.7%.  This revision has no material impact on     
estimated project life or investment returns.                                   
Development costs are estimated at US$400 million (BHP Billiton share US$230    
million).  The first copper production from the Norte open pit is scheduled for 
the fourth quarter of 2005.

MINERALS EXPLORATION                                                            
The exploration group of BHP Billiton Minerals continued to pursue global       
exploration opportunities for key commodities of interest to the group utilising
both the Junior Alliance Program and in house generative capabilities.  In line 
with this strategy, BHP Billiton purchased Hunter Exploration Group"s minority  
20% and 14% participating interests in the Aviat and Churchill Diamond Joint    
Ventures in Canada.                                                             
At the end of June 2003, BHP Billiton entered into an agreement with Diamond    
Mines Australia, a subsidiary of Gravity Capital, to explore for diamondiferous 
Kimberlite pipes in Australia using the FALCON(TM) airborne gravity technology. 
BHP Billiton has a 6.1% interest in Diamond Mines Australia and has back-in     
rights to a majority interest position in significant discoveries made as a     
result of this initiative.                                                      
Pursuit of global exploration opportunites and use of FALCON(TM) technology by  
the exploration group has led to continued growth and diversification in the    
exploration portfolio and increased the quality of exploration opportunities.   
The three BHP Billiton FALCON(TM)airborne gravity platforms were active in      
flying projects for both BHP Billiton and its partner companies in Australia,   
South America and Africa.                                                       
EXPLORATION EXPENDITURE                                                         
Information related to exploration expenditure will be included in the BHP      
Billiton full year results, to be released on 28 August 2003.   It is expected  
that gross exploration expenditure will be in line with previous forecast.
