UPGRADE OF WAFI/GOLPU RESOURCE                                                  
JOHANNESBURG, Tuesday 6 February 2007. Harmony Gold is pleased to announce an   
increase in its mineral resource at its Golpu copper gold project in the Morobe 
Province of Papua New Guinea.                                                   
The resource now stands at:                                                     
163Mt @ 1.1% Cu, 0.6g/t Au and 132ppm Mo containing                             
3.9 billion pounds of copper                                                    
2.96 million ounces of gold                                                     
47 million pounds of molybdenum.                                                
This represents an increase of 10% copper metal, 11% gold and 17% molybdenum.   
This increase in metal is primarily due to definition of a consistent halo of   
mineralised metasediment around the porphyry. The metasediment resource is a    
lower grade than the porphyry (see detailed table below) and thus has the effect
of lowering the overall grade of the resource, but importantly, the porphyry    
core has been confirmed with a slight increase in both volume and metal content.
The resource can be broken down as follows:                                     
Porphyry        92Mt @ 1.4% Cu, 0.7 g/t Au, and 108 ppm Mo                      
Metasediment    71Mt @ 0.7% Cu, 0.5g/t Au and 162 ppm Mo                        
The updated resource follows on from completion of a diamond drill hole program 
designed to further test the mineralisation and gain metallurgical and hydro-   
geological data for the Pre-feasibility study. The program consisted of 10      
PQ/HQ/NQ diamond drill holes completed for a total of 6,947m of drilling, of    
these 3,359m intersected the Golpu porphyry and 1,313m intersected              
mineralisation in the surrounding metasediment.                                 
Geological highlights of the drilling included:                                 
-    WR220 intersected high grade gold mineralisation in the potassic domain    
    with 210m @ 1.85g/t Au using a 1g/t Au cutoff.                              
-    WR224 - Metallurgical hole to test supergene and advanced argillic         
    alteration domains intersected 182m @ 2.89%Cu, 0.72 Au ppm and 1239 As ppm  
from 148m to 330m, including 70m @ 5.04% Cu 0.77 Au and 2255 As ppm from    
    148m to 218m.                                                               
-    Improved understanding of alteration patterns, and the alteration/arsenic  
    relationships which appear to be present. This understanding is key to      
successfully mining the deposit.                                            
LINK ZONE DRILLING                                                              
Continuing Pre-feasibility work includes confirmatory drilling on the Link Zone.
This program commenced in December 2006. Results from the first drill hole,     
WR231, designed to intersect the central portion of the lode returned a result  
of 49m @ 10.2 g/t Au, which confirms the broad and high grade nature of this    
deposit. Drilling is expected to be completed by May 2007 with a new resource   
model completed soon after.                                                     
The total resource of Wafi, as previously reported, amounts to 6.52Moz. This    
excludes the resources of Golpu.                                                
PRE FEASIBILITY STUDY                                                           
The Pre-feasibility study for Golpu is due for completion in July 2007. The     
integrated report which includes Golpu, NRG1 and Link Zone deposits is due later
in the year.                                                                    
As the majority of project development capital will be required for mining of   
the porphyry stock, it is hoped that the lower grade mineralised metasediment   
will be economic as only incremental mine development capital will be required  
for exploitation of the expanded resource.
