PRESS RELEASE
More significant exploration drill hole intercepts at Golpu - a world-class
copper-gold porphyry
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 Golpu
undertaken 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
WR348 561m@0.51g/t Au, 0.99% Cu from 179m including 209m@0.89g/t Au, 1.88% Cu from 359m
WR349 327m@0.39g/t Au, 1.23% Cu from 194m including 117m @0.63g/t Au,2.09% Cu from 262m
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 Golpu resource to the north with the ore body 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-Golpu exploration target1 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 project and 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 million2. 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 emphasise the potential for the
joint venture to establish another high quality, world-class operation in Papua
New Guinea."
