Statement of Ore Reserves                                                       
Johannesburg, Wednesday, 25 July 2007. Harmony Gold Mining Company              
Limited (Harmony) is pleased to publish its Statement of Ore                    
Reserves which has been produced in accordance with the South                   
African Code for the Reporting of Mineral Resources and Mineral                 
Reserves (The SAMREC Code) and the Australian Code (The JORC Code)              
as at 30 June 2007.                                                             
Harmony announces gold Ore Reserves of 53.6 million ounces as at                
30 June 2007. Despite the disposal of assets, successful pre-                   
feasibility studies have added additional ounces to our reserves.

As indicated in the table above, Harmony`s Ore Reserves as at 30                
June 2007 reflects a year-on-year depletion of 2.4 million ounces               
when compared with the combined ore reserves for 30 June 2006.                  
Disposals of assets, shaft closures, and the loss of the Western                
Areas equity ounces accounts for a further decrease of 5.3 million              
ounces of reserves.                                                             
The successful pre-feasibility studies at Harmony`s Evander South               
Project as well as Golpu in Papua New Guinea (PNG) added 3.5                    
million ounces to the reserves. A further increase of 1.8 million               
ounces is attributable to growth in the reserves from the South                 
African operations.                                                             
A gold price of US$520/oz was used for the conversion of Mineral                
Resources to Ore Reserves at our South African and Australasian                 
operations. An exchange rate of USD/ZAR6.88 for South Africa and                
AUD/USD 0.73 for Australia has been used, resulting in a gold                   
price of R115 000/kg or A$712/oz respectively.

Harmony also announces the completion of pre-feasibility studies                
for the Golpu copper/gold deposit, located at the Wafi/Golpu site               
in the Morobe province of PNG. The Wafi pre-feasibility currently               
underway is due for completion in October 2007.                                 
The highlight of the pre-feasibility study is the definition of a               
probable ore reserve of 70.8 million tonnes grading 1.13% copper,               
0.61g/t gold, and 121ppm molybdenum. Importantly, the mining plan               
has restricted the overall average arsenic grade to 136ppm, with                
the highest grade in any single year restricted below 300ppm, to                
ensure that a saleable concentrate is maintained throughout the                 
project life.                                                                   
Further analysis undertaken during the pre-feasibility study                    
indicates that inclusion of inferred material in the mining plan                
may see the mining inventory increase to 100.7 million tonnes                   
grading 0.95% copper, 0.54g/t gold, and 129g/t Molybdenum. Based                
on this mining inventory and metal prices of $2.30/lb copper and                
$520/oz gold, the mine will have a production life of                           
approximately 13 years, recovering 64 000 tonnes of copper, and 73              
000 ounces of gold to concentrate per year.

This Statement forms part of the company`s Mineral Reserves and                 
Mineral Resources declaration which will be published in our FY                 
2007 annual report towards the end of September 2007.                           
In addition our annual report will contain full details of our                  
uranium resources. In the meantime, we are pleased to declare the               
following uranium mineral resources within the measured resource                
category, as a result of an extensive drilling exploration                      
programme:                                                                      
 -    5 tailings dams in Randfontein; 360 million tonnes                        
 containing 79 million pounds of U3O8                                           
-    6 tailings dams in the Free State; 190 million tonnes                     
 containing 30 million pounds of U3O8                                           
The resources quoted above represent total contained dump                       
resources and no economic cut-offs have been applied. Economics of              
dual pay limits have also not been applied.                                     
Chief Executive Bernard Swanepoel says, "The FY 2007 annual report              
will be the first report in our 57 year history in which we will                
declare copper, molybdenum And uranium reserves and resources.                  
Despite the fact that we have always owned uranium, it was always               
treated as a mere by-product and off-set against cost. The results              
of our uranium deposits prove to be worthwhile to proceed to                    
feasibility study stage".
