Share code: HAR     ISIN: ZAE000015228                                          
("Harmony")                                                                     
10 March 2005                                                                   
Further extension of the closing date of the subsequent offer                   
Harmony hereby announces that the expected closing date of the subsequent offer 
is hereby extended to 12.00 p.m. (South African time) on Friday, 20 May 2005.   
Harmony will notify shareholders by means of a public announcement of any       
amendment to the expected closing date of the subsequent offer set out above.   
Harmony announces that as at 5.00 p.m. (South African time) on 9 March 2005,    
valid acceptances of the subsequent offer had been received in respect of a     
total of 128 910 Gold Fields shares.  As previously announced, Harmony considers
this level of acceptances to be entirely consistent with customary market       
practice where an offer is still awaiting approval from the competition         
authorities.                                                                    
In addition, as previously announced, Harmony has received an irrevocable       
undertaking from Norilsk to accept the subsequent offer in respect of 98,467,758
Gold Fields shares, representing approximately 20.03% of the entire issued share
capital of Gold Fields.                                                         
Accordingly, Harmony now either owns, has received valid acceptances of the     
subsequent offer or has an irrevocable undertaking to accept the subsequent     
offer in respect of a total of 155 326 496 Gold Fields shares representing      
approximately 31.6% of the entire issued share capital of Gold Fields.
