Harmony Gold Mining Company Limited - Gold Fields Limited in breach of

Harmony Gold Mining Company Limited                                             
(Incorporated in the Republic of South Africa)                                  
(Registration number 1950/038232/06)                                            
Share code: HAR     ISIN: ZAE000015228                                          
("Harmony")                                                                     
15 November 2004                                                                
Gold Fields Limited in breach of confidentiality agreement                      
Harmony has received several enquiries from the media regarding a document      
prepared by HSBC Bank plc ("HSBC") in August 2004.  Harmony understands that    
this and other documents were provided to the media by Edward Nathan & Friedland
(Proprietary) Limited ("ENF"), legal advisers to Gold Fields, on the evening of 
Friday, 12 November 2004.                                                       
It should be noted that the release of these documents to the media by Gold     
Fields Limited ("Gold Fields") and its advisors represents a breach of the      
confidentiality agreement under which these documents were provided to ENF and a
breach of the basis on which the documents could be used by Gold Fields: that is
to say, for the purposes of the Competition Tribunal and not for their          
distribution to the media.                                                      
The document refers to a possible transaction between Harmony, Gold Fields and  
JSC MMC Norilsk Nickel ("Norilsk") which would involve the separation of the    
companies respective South African and international assets into two separate   
entities.                                                                       
Harmony, in common with all major corporations, regularly receives unsolicited  
proposals of this kind from investment banks.  In recent months, and            
particularly after the announcement of the acquisition by Norilsk of Anglo      
American"s stake in Gold Fields, Harmony received various proposals regarding,  
inter alia, a proposed takeover of Gold Fields from a number of investment banks
including, J.P. Morgan plc ("J.P. Morgan"), Investec Bank Limited ("Investec")  
and HSBC.                                                                       
It should be noted that the JP Morgan proposal was submitted after it had been  
appointed as adviser to Gold Fields.                                            
Harmony has not implemented, and does not plan to implement, any of the ideas   
submitted by J.P. Morgan, Investec or HSBC in this period but has developed its 
own strategy which it is now pursuing.                                          
Harmony believes its own strategy is a unique opportunity for Gold Fields       
shareholders, creating the world"s largest gold mining company by reserves and  
production.                                                                     
ENDS                                                                            
In connection with the proposed acquisition of Gold Fields, Harmony has filed a 
registration statement on Form F-4, which includes a preliminary prospectus and 
related exchange offer materials, to register the Harmony ordinary shares       
(including Harmony ordinary shares represented by Harmony American Depositary

Fields shareholders wherever located, as well as a Statement on Schedule TO.
