Higher gold price more than doubles cash operating profit

August 07, 2006

---

Harmony Gold Mining Company Limited (NASDAQ/NYSE: HMY JSE: HAR) today announced its results for the June 2006 quarter. Cash operating profit increased from R305.6 million in the March 2006 quarter to R645.2 million (111.1%) in the June 2006 quarter. The main reason for this improvement was as a result of the revenue received, which went up by 19% and tighter cost control that did not go up commensurately with the increased volumes that were mined. Cash earnings showed a 109% improvement, from 78 cents to 163 cents per share for the June quarter.

On the revenue side the gold price received for the June quarter improved from R110 399/kg to R131 358/kg. This resulted in the cash operating margin improving from 15,9% to 28,5%. Gold production decreased with 1.3% to 17 243kg quarter on quarter. “Harmony once again demonstrated that we offer to our shareholders significant upside potential when the gold price rises. We have stepped up our development rates to give us more mining flexibility, which in turn will allow us to take advantage of the higher gold price. This is a process that will continue for the next 18 months, but we expect to start reaping the benefits by the end of the fiscal year.” Commented Bernard Swanepoel, Chief Executive.

The performance of the company is best highlighted in the following table:
