PHAKISA MINE: EXPLOSION UPDATE                                                  
Fourth rescue team member dies                                                  
Harmony Gold Mining Company Limited (Harmony) regrets to announce that Mr Josie 
Randall, a member of the Mines Rescue Services team (proto team) injured in an  
underground explosion on Thursday, 24 June 2010 at Harmony`s Phakisa Mine near  
Welkom in the Free State, has died.                                             
This brings to four the number of specialised  proto team members who died as a 
result of the explosion, which occurred while the team were attending to a fire 
on 66 Level, some 2 013 metres below surface late on Thursday night. A fifth    
team member is in a serious but stable condition in hospital.                   
Harmony`s CEO Graham Briggs said today that, while the cause of the explosion   
was not yet known, he was extremely concerned to have been informed that, while 
work was being done to restore ventilation to 66 Level, `booby trap` explosive  
devices (similar to those made by criminal miners) had been discovered some 900 
metres from the accident scene.                                                 
Briggs said the company was doing everything in its power to rid its mines of   
criminal miners, with the full knowledge and assistance of the DMR and the SAPS.
"Measures include the installation of additional security fencing and biometric 
and security card readers at all shafts, the banning of food being taken        
underground, and implementation of an amnesty, of which 102 criminal miners took
advantage and returned to surface."                                             
Briggs expressed his personal condolences and those of the company, to the      
families and colleagues of the proto team members who have died.                
"These men were volunteer members of a highly trained, experienced corps of mine
rescue workers, extremely knowledgeable about mine safety standards, who risk   
their lives to save those of others in danger. It is tragic and extraordinary   
that they have died in these circumstances, and we will spare no efforts to     
determine the cause."                                                           
Briggs said that: "At this stage of the investigation we simply do not know what
happened."                                                                      
The full investigation to establish the causes of the accident will continue    
during the week.                                                                
Ends.
