ANGLOGOLD ANNOUNCES MINERAL RESOURCES AND ORE RESERVES
AS AT 31 DECEMBER 2003
At the time of its formation, AngloGold's reserve base was associated almost entirely with deep-level mining operations in South Africa. Although the company currently has a number of South African organic growth projects in development, these deep-level orebodies are finite assets, whose limits, up to a maximum depth within the bounds of current technology and practice, have largely been defined. There are limited prospects therefore for growing the South African reserve base. Consequently, AngloGold has, since its inception, set about seeking to expand its asset and reserve base by acquiring companies and exploring for orebodies that will host long-life, high-margin operations. The soon-to-be-completed merger with Ashanti Goldfields, which will increase AngloGold's Ore Reserves by some 30%, primarily in the form of the long-life, high-margin operations of Obuasi and Geita, is an example of the success of this strategy.
The AngloGold Ore Reserve and Mineral Resource statement as at the end of 2003 illustrates the continuation of this pattern:
Brownfields exploration generated 3.4Moz of Mineral Resource at a discovery cost of US$7.79/oz. A further 1.3Moz was added to the Mineral Resource with the inclusion of Moab Extension, situated to the south of Kopanang.
The conversion of Mineral Resources to Ore Reserves added an additional 1.8Moz of Ore Reserve at a cost of US$5.2/oz, with a further 0.8Moz added with the inclusion of Moab Extension.
The total Mineral Resource decreased by 74.9 Moz from 287.6Moz in 2002 to 212.7Moz in 2003. This was primarily due to a revision of the mining depth limit at Western Ultra Deep Levels (WUDLS) from 5km to 4.5km below datum and an increase in the Mineral Resource cut-off grade from 600cmg/t to 750cmg/t, resulting in a net loss of 64.8Moz. In addition to this change at WUDLS, depletion as a result of mining of Mineral Resources during 2003 reduced the total Mineral Resource by 6.6Moz.
The total Ore Reserve decreased by 9.2Moz from 72.3Moz in 2002 to 63.1Moz in 2003. The key features of thus reduction were:
Assumptions
In respect of AngloGold's South African assets, Ore Reserves were determined assuming
a gold price of US$350/oz and an exchange rate of ZAR7.00 = US$1. This compares with
a gold price of US$325/oz and an exchange rate of ZAR10.50 = US$1 as at 31 December
2002.
In respect of assets in East and West Africa, Ore Reserves were determined assuming a gold price of US$350/oz.
In respect of assets in South America, Ore Reserves were determined assuming a gold price of US$350/oz, with the exceptions of Cerro Vanguardia, as well as certain parts of Morro Velho, namely Engenho D'Agua and Corrego Do Sitio. The Ore Reserves for Cerro Vanguardia, Engenho D'Agua and Corrego Do Sitio were determined at US$325/oz.
Ore Reserves for Cripple Creek & Victor in North America were determined assuming a gold price of US$325/oz.
Ore Reserves at AngloGold's Australian assets were determined assuming a gold price of
US$234/oz and at an exchange rate of A$1 = US$0.55 for Boddington (based upon the
gold price and exchange rate assumed for the 2000 feasibility study) and at US$350/oz
and an exchange rate of A$1 = US$0.63 for Sunrise Dam. The Ore Reserve estimates in this document include Ore Reserves below current
infrastructure in the case of certain South African mines. However, these Ore Reserves
have been determined based upon completed feasibility studies.
Ore Reserve Statement
The Ore Reserves as at 31 December 2003, show a year-on-year decrease of some 9.2Moz from 72.3Moz as at 31 December 2002 to 63.1Moz. The reduction in Ore Reserves includes a depletion of 6.3Moz (being the ore delivered to metallurgical plants and the corresponding reduction in the applicable Ore Reserve).
The principal changes in AngloGold's Ore Reserves for 31 December 2003 relative to those as published as at 31 December 2002, for reasons other than depletion, are as follows:
In the case of surface, open-pit mines the procedure is as follows: Revenue and costs are calculated for each mining block within a three-dimensional model of the orebody using assumed values for gold price, operating costs, metallurgical recoveries and slope angles. An optimisation process is then applied to determine all the blocks combined within the model that make a positive contribution under these assumptions. Within this process a cut-off grade is applied which determines the ore blocks to be treated and included in Ore Reserve. These blocks are scheduled with consideration being given to practical mining considerations and limitations. Scheduled ore blocks that are classified as Proved or Probable constitute the Ore Reserve.
Mineral Resources and Ore Reserves are reported in accordance with the Australasian Code for Reporting of Mineral Resources and Ore Reserves (the JORC Code) and the South African Code for the Reporting of Mineral Resources and Mineral Reserves (the SAMREC Code).
