New Mining Order Right                                                          
Central Rand Gold remains firmly on track to be awarded its New Order Mining    
Right by the South African Department of Minerals and Energy (DME). The approval
process is well advanced and the Company looks forward to concluding the process
in the short term.                                                              
The Mining Right application was accepted by the DME on August 8 2007 and has   
been supplemented by the implementation and submission of all other necessary   
processes and documentation.                                                    
Exploration Update                                                              
Considerable exploration activity has taken place resulting in ongoing drilling,
assaying and bulk sampling initiatives across the Company`s prospecting areas.  
Bulk Sampling                                                                   
Underground bulk sampling has confirmed mineralisation outside of reefs and     
substantial thicknesses of mineralised grits have been identified.              
Significantly, mineralised halos have also been identified in the hanging wall  
and foot wall of conglomerate bands.  Underground bulk sampling is currently    
investigating these mineralised zones.                                          
As part of CRG`s exploration programme (surface mapping, diamond drilling, shaft
re-access and resource conversion investigations), zones of mineralisation (in  
the form of pervasive disseminated pyrite and grit bands) have been identified  
in the hanging wall of the Main Reef Leader and the South Reef on CMR.          
CRG has undertaken an extensive bulk sampling exercise to quantify these        
mineralised zones. These zones of mineralisation have the potential to add to   
the mineable tonnage and resource estimates. This also suggests that mass mining
in larger stopes will be viable.                                                
The Company embarked on its underground sampling process in June 2008. The first
samples were obtained through access via East Shaft (Consolidated Main Reef) on 
5 level (60 metres below surface).                                              
Approximately 100 metres of strike was sampled from the hanging wall of the     
South Reef utilising a method referred to as "slyping".  This involves drilling 
holes of approximately 200 to 500mm (spaced about 1m apart) into the hanging    
wall and utilising expanding gas cartridges to "pop" off the sample. The        
sampling is geologically controlled and a single bulk sample can be made up of  
10 to 15 separate entities, depending on the geological feature being analysed. 
A bulk sample can weigh up to 0.5 ton.                                          
The initial results have become available and are proving to be encouraging     
(Table 1). This represents a range of 0.5 g/t to 1731 g/t from each 0.5 tons of 
homogenised sample.

The implications of these results are significant. They show that the source of 
gold is not only confined to the conglomerate bands, but are also present in    
grit bands, zones of disseminated pyrite and in inter-conglomerate quartzites.  
This finding would add significantly to the amount of tonnage and resources     
available for mining.                                                           
Bulk sampling is continuing and is currently focusing on a cross-cut from the   
Main Reef to the South Reef (on 5 level, East Shaft) and on 9 level (+/-190m    
below surface, East Shaft) and will commence in the near future on 5 level, New 
Unified Shaft (CMR, approximately 3500m to the west of East Shaft).

Additional Resources                                                            
Regional mapping first indicated the presence of mineralisation outside the     
conglomerate bands or `reefs`. Drilling these occurrences has confirmed zones of
mineralisation in disseminated pyrite and grit bands outside the known reefs.   
Following on from this discovery, underground exploration has confirmed its     
presence. It became apparent that quantifying these additional sources of gold  
would have to be through bulk sampling. Channel sampling produces a 1 in 12000  
representation whereas bulk sampling produces a 1 in 200 representation making  
the data more reliable.                                                         
The results from the underground bulk sampling are significant as they confirm  
the presence of mineralised material outside the conglomerate bands in zones of 
disseminated pyrite, grit bands and inter-conglomerate quartzites. This finding 
would also add significantly to the amount of mineable tonnage.

Gold production ramp-up                                                         
The Company is on schedule to meet its initial target of producing gold at an   
annualised rate of 100,000 ounces by the end of 2009 with trial mining to begin 
in October 2008.                                                                
Trial Mining                                                                    
The Company has purchased a plant with the capacity to process ore at a rate of 
20 tons an hour from trial mining. The plant, acquired from Gekko Systems in    
Australia at a cost of US$5.74 million, comprises a communication circuit, a    
gravity circuit and a flotation circuit.                                        
It is expected that the plant will be shipped from Melbourne in August 2008 and 
is scheduled to arrive in Johannesburg mid September. It will be erected and be 
suitable for commissioning shortly after its arrival.                           
The trial mining plant, which will be situated on the surface, is expected to be
fully commissioned in October and is expected to ramp up in the following months
to a target rate of around 12,000 tons of ore per month.                        
Trial mining will confirm the Company`s mining and metallurgical concepts and   
determine the final configuration of mining/processing requirements, leading to 
the commencement of full scale mining from surface deposits by the end of the   
first quarter of 2009.                                                          
Full scale mining                                                               
Full scale mining of already targeted surface deposits (down to 10m below       
surface) and shallow underground mining (between depths of 10m to 70m) will     
begin by the end of Q1 2009. The first three mining slots will be accessed for  
surface mining as well as providing access for the company`s ongoing drilling   
and underground bulk sampling programmes.
