HAR - Harmony Gold Mining Company Ltd - Press Release Harmony Gold Mining Company Ltd Incorporated in the Republic of South Africa Registration number: 1950/038232/06 JSE Share code: HAR NYSE Share code: HMY NASDAQ Share code: HMY ISIN: ZAE000015228 PRESS RELEASE PROMISING FUTURE FOR WAFI-GOLPU AS HARMONY REPORTS FURTHER SIGNIFICANT INCREASE IN THE MINERAL RESOURCE Johannesburg. Thursday, 29 July 2010. Harmony Gold Mining Company Limited (Harmony) is pleased to announce a significant increase in the Mineral Resource at the Wafi-Golpu porphyry copper-gold project in Papua New Guinea (PNG), which is part of the company`s 50/50 joint venture with Newcrest Mining Limited. The mineral resource for Wafi-Golpu now contains 16 million ounces (Moz) of gold and 4.8 million tones (Mt) of copper. Expressed as gold equivalents, this resource amounts to 38.5 Moz of gold, which spells an exciting and promising future for this project and also provides great opportunities for investors. The increase in the Mineral Resource is due to the discovery of a new zone of mineralization directly adjacent to the previously defined Golpu resource. The mineralization has been extended by the drilling along strike to the northeast and at depth. The estimate is based on an additional 19 179 m of drilling in 22 PQ/HQ/NQ diamond drill holes. Contained metal at Golpu only, has increased from the 2007 mineral resource (163Mt at 0.57 g/t Au, 1.08% Cu, 132 ppm Mo) as follows: - gold increased from 3.0 to 8.8 Moz of gold; - copper increased from 1.8 to 4.8 Mt of copper; - molybdenum increased from 22 to 55 kt of molybdenum; and - on a gold equivalent basis the deposit increased to 30.9 Moz Au equivalent. Harmony CEO Graham Briggs says, "These results have a profoundly positive impact on our future resource base and drilling results continue to prove that investing in exploration was a very good long term decision." The drill programme at Golpu is testing an exploration target in the range of 500 to 800 Mt at high grades of between 0.7% and 1.1% copper (Cu) and 0.5 to 0.7g/t gold (Au) for 8 to 18 Moz of gold and 3.5 to 8.8 Mt of copper. This target includes the current resource(2). Briggs adds, "We have now added significant size to what is one of the highest grade copper gold porphyries in South East Asia and potential for further growth in this Mineral Resource remains highly promising." Over the broader project area including the Wafi gold deposit, a number of targets have been earmarked for follow-up testing, with several that already contain significant gold intercepts. At Golpu, the mineralized footprint of the deposit now extends over 700m of strike and remains open to the north and at depth. The ongoing drilling programme, involving five drill rigs continues to expand high-grade zones of mineralized porphyry.
