Johannesburg. Friday, 22 October 2010. Harmony Gold Mining Company Limited
(Harmony) is pleased to announce further significant exploration drill hole intercepts
at the Golpu porphyry copper-gold deposit at the Wafi-Golpu Project in Papua New
Guinea (PNG), which is part of the company’s joint venture with Newcrest Mining
Limited (Newcrest).

During the past quarter Harmony released an updated Statement of Reserves and
Resources which included an appreciable increase in the Wafi-Golpu Resource to
16Moz of gold and 4.8Mt of copper.Additional exploration drilling at Golpuundertaken
during the quarter has further extended the deposit with significant intercepts as
follows:

•

WR347 799m@1.43g/t Au, 1.90% Cu from 883m including 616m @
1.79g/t Au, 2.34% Cu from 910m

•

•

WR347 was drilled as a 100 metres step-out hole on the northern margin of the
existing resource. The intercept correlates with a zone of bornite mineralisation and
represents the highest grade results ever returned from drilling at the project. This
intersection significantly extends the higher grade core of the Golpuresource to the
north with the orebody remaining open in this direction and at depth.

WR349 indicates that the high grade porphyry mineralisation extends to the north and
closer to the surface than previously modelled.

As a result of this drilling, the Wafi-Golpuexploration target 1 has been upgraded to
30Moz of gold and 8Mt of copper based on a tonnage range between 900 and 1,400
million tonnes. This targets growth of epithermal deposits to between 100 and 200
million tonnes at a grade range between 1.5g/t and 2.0g/t plus porphyry deposits to a
range of 800 and 1,200 million tonnes at grades between 0.7 and 1.1% copper and
0.5g/t to 0.9g/t gold.

Furthermore Harmony is pleased to announce that the Wafi-Golpu concept study was completed during August 2010.
The concept study was building on previous studies and was updated with new information and enhanced
development approaches during the study. The concept study demonstrates that a very robust business case exists
for the projectand therefore both Harmony and Newcrest have approved that the project progresses to the rre-
feasibility study phase.

The main value drivers, for which several options will be considered during the pre-feasibility study, are:

•    Further increasing the tonnage and grade of the resource;
•    Optimise the production rates from the panel caves to suit the footprint and draw heights;
•    Optimise the gold recovery of the refractory Wafi ore bodies; and
•    Positioning of infrastructure, waste dumps and tailings storage facilities in such areas to minimize the impact
     on the environment and to optimise the costs

The joint venture study team is targeting completion of the pre-feasibility study towards the end of 2011 or early 2012.
The Pre-Feasibility Study costs, which includes the construction of a new road, the establishment of a camp and
associated infrastructure and the commencement of underground exploration access (decline shaft) is estimated to be
US$150 million 2. Approval for the construction of the access road and establishment of a camp and associated
infrastructure has been obtained from the local landowners and construction of the new road will commence early
during 2011.

Harmony CEO Graham Briggs says, “We can hardly contain our excitement each time new drilling results are
received. The latest intercepts, together with the very positive outcome of the concept study emphasisethe potential
for the joint venture to establish another high quality, world-class operation in Papua New Guinea.”

Ends.
