UPDATE ON ELECTRICITY SUPPLY                                                    
Johannesburg, Wednesday 30 January 2008. In keeping our stakeholders updated,   
Harmony Gold Mining Company Limited (Harmony) advises that following yesterday`s
meetings with Eskom and government officials, the company was allocated another 
5% electricity supply, bringing our supply to 80%.                              
Consequently the majority of our mines are working based on the strategy plan   
devised for this eventually. We have a varying staff complement on our mines    
with no production workers on some mimes, 60% or only care and maintenance      
workers on other mines, and the rest at full complement.                        
The higher grade mines with 100% complement include Elandsrand, Randfontein,    
Tshepong, Evander and the some of the Virginia operations, those at 60%         
complement are Target, Masimong, and Phakisa; the rest of the mines are focusing
on project work or care and maintenance.                                        
We have stopped most of the support infrastructure and some of the metallurgical
mills from operating during the country`s peak consumption periods. In some     
cases hoisting of ore is done between midnight and five in the morning when the 
country`s consumption is at a low peak.                                         
Yesterday our consumption levels were around 300MW and peaked at 400MW (at 3:00 
am) which is our 80% allocation. This morning we are back to 75% taking into    
account the country`s day-time needs.                                           
At present there exists excellent communication between Eskom and Harmony and   
regular updates are being received on the power supply situation. Eskom will be 
phasing in the mining industry`s power requirements and we expect to be         
operating at the allocated 90% requirement on 31 January 2008.                  
ends.
