  BHP BILLITON QUARTERLY REPORT ON EXPLORATION AND DEVELOPMENT ACTIVITIES         
  January 2004 - March 2004                                                       
  This report covers exploration and development activities for the quarter ended 
  31 March 2004.  Unless otherwise stated, BHP Billiton"s interest in the projects
  referred to in this report is 100 per cent, and references to quarters are based
  on calendar years.                                                              
  Of the 12 projects that were under construction during the quarter, 10 are      
  within Board approved expenditure limits and are tracking on or ahead of        
  schedule.  (Refer to comments on Dendrobium Coal Project on page 4.)  The       
  exceptions are Minerva and the ROD Integrated development.  The Products and    
  Capacity Expansion Project (PACE) was commissioned during the quarter, under    
  budget and ahead of original schedule.  The Ravensthorpe Yabulu Integrated      
  Nickel project and the Escondida Sulphide Leach project have recently been      
  approved by the Board of Directors.                                             
  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.  The  
  sanctioned facility is designed to produce at a daily rate of up to 150,000     
  barrels of oil and 180 million cubic feet of natural gas.  Fabrication of the   
  hull began with the cutting of first steel at the shipyard in South Korea.      
  Fabrication of the topsides and hull facilities continued during the quarter.   
  The project remains on budget and on schedule for first production in the third 
  quarter of 2006.                                                                
  Mad Dog Development, Gulf of Mexico, USA  (BHP Billiton 23.9%, non-operated)    
  BHP Billiton announced its sanction of the Mad Dog field in February 2002,      
  approving up to US$335 million for development of the Gulf of Mexico oil and gas
  field. During the quarter the hull arrived from Finland, was towed to its       
  location and successfully upended on 22 February 2004.  Mooring installation is 
  complete.  Work on the living quarters was completed in Sweden and the module   
  arrived in the USA.  Topsides fabrication is continuing in the USA. At the end  
  of March 2004, the overall facility was approximately 85 per cent complete.     
  First production remains on schedule for the end of 2004.                       
  Greater Angostura Development, Trinidad (BHP Billiton 45%, operated)            
  In March 2003, BHP Billiton approved US$327 million for the first development   
  phase of the Greater Angostura oil and gas field off the northeast coast of     
  Trinidad.  During the quarter fabrication continued on onshore facilities,      
  including oil storage tanks, pipelines and associated infrastructure.           
  Construction is complete on all four wellhead protector platforms, with one     
  already positioned offshore, and the remaining offshore facilities are being    
  prepared for installation and commissioning.  The project remains on budget and 
  first oil production is on schedule for the end of 2004.                        
  North West Shelf expansion, Australia (BHP Billiton 16.67%, non operated)       
  Overall progress on the fourth liquefaction processing train is 89 per cent     
  complete and remains on schedule to start up in mid 2004.  Construction is 82   
  per cent complete and pre-commissioning of some packages has commenced.  The    
  second trunkline was commissioned in mid February.  BHP Billiton"s share of     
  capital expenditure is US$247 million.                                          
  ROD Integrated Development, Algeria (BHP Billiton 36.04%, joint operating entity
  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. At the end of March 2004, the development drilling programme of  
  24 new development wells and one workover had been concluded and the rig was    
  being de-mobilised.  34 development wells are currently available for production
  operations, 11 of which are completions of exploration and appraisal phase      
  wells.  Procurement of major equipment and bulk materials is complete.  Process 
  pipework spool prefabrication has been completed and delivered to the site.     
  Over 5 million workhours have been completed at the construction site without a 
  Lost Time Incident.  Overall project progress is 87 per cent complete.  First   
  production is scheduled for the middle of calendar year 2004, one quarter behind
  the original schedule.  BHP Billiton"s share of capital expenditure is US$192   
  million.                                                                        
  Minerva (BHP Billiton 90%, operated)                                            
  In September 2003, BHP Billiton changed the contractual arrangements relating to
  the design and construction of the Minerva development.  A new managing         
  contractor was appointed in October 2003 to complete the gas plant, and         
  engineering has progressed to an advanced stage.  Procurement activities are    
  well underway and most long lead time items have been ordered.  Construction    
  activities are increasing as concrete foundations are poured and delivery of    
  equipment commences.  All other parts of the Minerva Development are now ready  
  to produce, with the Minerva 3 and 4 wells completed, onshore and offshore      
  flowlines installed, and all tie-ins made from wellhead through to gas plant.   
  Following a review of the project"s targets, initial production is now expected 
  in the fourth quarter of calendar year 2004, and BHP Billiton"s share of capital
  expenditure is expected to be US$150 million.                                   
  Caesar/Cleopatra Transportation Systems, Gulf of Mexico, USA (BHP Billiton      
  interest in Caesar pipeline, 25%; interest in Cleopatra pipeline, 22%. Non-     
  operated)                                                                       
  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.  Installation
  of the Cleopatra and Caesar portions has been completed to a third party        
  facility and to Mad Dog.  Expenditure of up to US$132 million has been approved 
  by the Board for this project.  The project is on budget and on schedule to     
  commence operation coinciding with first production at third party facilities,  
  in advance of first hydrocarbon production from Mad Dog and Atlantis.

  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.   
  The initial stripping shovel and associated haul trucks were moved into the     
  Escondida Norte site in early December 2003.  The second fleet commenced during 
  February 2004.  Pre-mine waste stripping continued during the quarter, using    
  both contractor and Escondida equipment. Total material movement in the pre-mine
  to the end of March 2004 was 20.9 million tonnes.  Construction activities      
  continued on the initial infrastructure requirements including maintenance      
  facilities, mine fuel station, electrical substations, service roads and        
  offices.  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).                                                                
  Escondida Sulphide Leach, Chile (BHP Billiton 57.5%)                            
  The Escondida Sulphide Leach project was approved in April 2004.  The project   
  will produce 180,000 tonnes (103,500 tonnes BHP Billiton share) of copper       
  cathode per annum, utilising a bacterially assisted leaching process on low-    
  grade run-of-mine ore from both the Escondida and Escondida Norte pits.  The    
  resulting solutions will then be treated in conventional solvent extraction and 
  electrowinning plants.  Development costs are estimated at US$870 million       
  (US$500 million BHP Billiton share) and production is scheduled to begin during 
  the second half of 2006.

  Products & Capacity Expansion Project, Australia (BHP Billiton 85%)             
  The project provides for the upgrade of the BHP Billiton rail and port          
  facilities in a staged process to meet forecast increases in sales of iron ore. 
  Construction work was completed, and commissioning and performance testing      
  activities continued during the quarter.  The first shipment of iron ore was    
  loaded from the new facilities at the end of January 2004, ahead of the original
  schedule.  The project was completed at a cost of US$315 million (BHP Billiton  
  share US$268 million) compared with the budget of US$351 million (BHP Billiton  
  share US$299 million).  This project will no longer be included in this report. 
  Dendrobium Coal Project, Australia                                              
  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).  The main customer for 
  the coking coal is BlueScope Steel, located seven kilometres from the mine site.
  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.  Difficulties have been experienced with underground   
  mining conditions during the quarter, slowing development rates.  One mining    
  unit has passed through this zone and is again producing at above expected      
  rates.  It is anticipated that the other two units will have passed through this
  zone before the end of May 2004 at which time the project costs will be         
  reviewed.  We continue to expect longwall commencement in the middle of calendar
  year 2005.

  Ravensthorpe Yabulu Integrated Nickel Project, Australia                        
  The Ravensthorpe Yabulu integrated nickel project was approved in March 2003.   
  The project includes the development of a mine, treatment plant and associated  
  infrastructure near Ravensthorpe in Western Australia, and the expansion of the 
  QNI Yabulu refinery near Townsville in Queensland.  The Ravensthorpe processing 
  plant will produce a mixed nickel cobalt hydroxide intermediate product, which  
  will be packaged and shipped to Yabulu for final refining.  The capital cost for
  the combined project is expected to be US$1.4 billion.  Construction is expected
  to commence in late 2004, with first nickel metal production from the expanded  
  Yabulu refinery expected in late 2007.
