The Harmony Gold Mining Company Limited today announced that their SAMREC compliant consolidated ore reserves statement shows an increase of 3.4% from 54.1 million ounces to 56.0 million ounces for the year ending 30 June 2006.

Ore reserve reconciliation: FY2005 to FY2006

	Gold (tonnes)	Gold (million ounces)
Balance at June 2005	1,684	54.1
Mined during FY2005	­76	(2.4)
Added equity ounces from Western Areas	131	4.2
Other adjustments	3	0.1
Balance at June 2006	1,742	56.0
% Difference from June 2005 to June 2006	3.44%

As reflected in the table above, Harmony’s Ore Reserves show an overall depletion of approximately 2.4 million ounces for the financial year. The 29.2% equity ounces from

Western Areas added 4.2 million ounces to the ore reserves, resulting in most of the positive increase as indicated.

The mineral resources have increased from 528,6 million ounces to 537,6 million ounces mainly as a result of an additional 9,8 million ounces, which came from Harmony’s 29,2% stake in Western Areas.

A gold price of US$500/oz was used for the conversion of Mineral Resources to Ore Reserves at our South African and Australian operations. An exchange rate of USD/ZAR6.53 for South Africa and AUD/USD 0.74 for Australia has been used, resulting in a gold price of R105 000/kg or A$680/oz respectively. These gold prices were also used in the calculations of mine planning.

The Hidden Valley feasibility study at Papua New Guinea was completed using a gold price of US$445/oz and a silver price of US$6.50/oz. These prices were also used in the declaration of Ore Reserves.

Independent consultant SRK has audited the Harmony South African and Australia June 2006 Mineral Resources and Ore Reserves. The Papua New Guinea Mineral Resources and Ore Reserves were independently audited by RSG Global. The 29,2% Western Areas equity ounces were extracted from their audited reserve statement in their Annual Report of December 2005 and adjusted for depletion for the period from January 2006 to June 2006.
