DEEP DRILLING AT LOULO BOOSTS RESOURCE BASE

Zurich, Thursday 21 April 2005 - London and Nasdaq listed gold miner Randgold Resources said today its attributable resource base had grown by more than 20% from less than 8 million ounces at the end of 2003 to 10.02 million ounces a year later.

Addressing the European Gold Forum in Zurich, Randgold Resources CEO Dr Mark Bristow said the main contributor to the increase at the company's Loulo project in Mali had been deep drilling of the Yalea orebody where total measured, indicated and inferred resources now stood at 5.2 million ounces for that ore body alone. Total resources for the project, when Loulo 0 is included, are now a robust 8 million ounces. The ongoing drilling forms part of a study, currently being completed by SRK Consulting, on the development of underground operations on both orebodies to boost the Loulo open-cast mine which was scheduled to start producing gold in July this year, he said.

At the company's Morila joint venture, also in Mali, drilling of the MSZ extension to the main orebody has resulted in the partial replacement of the resources depleted by the mining operation during the year. More drilling is planned to convert the additional resources to the reserve category.

Overall, the company's attributable reserves increased slightly to 2.51 million ounces, mainly on the back of an increase in the Loulo reserve from 1.42 million ounces to 1.85 million ounces. Significantly, the higher-confidence proved-reserve category makes up 66% of attributable proved and probable reserves.

"The substantial resource growth at Yalea has vindicated the company's high expectations of the Loulo project and we are still bullish on the prospects of finding more in this region," said Bristow.

"The orebody has passed the 5 million ounce mark and is still growing, construction of the open-cast mine is on schedule and the latest drilling results confirm the potential for the development of long-life underground mines to exploit the extensions of the Yalea and Loulo 0 pits. Meanwhile, we are also expanding our footprint in other prospective areas to further increase our resource base through organic growth," he said.
