SUSTAINED FOCUS ON ORGANIC GROWTH DELIVERS SUBSTANTIAL RISE IN RESERVES
AND RESOURCES

London, 31 March 2010 - Randgold Resources today reported a 69%
increase in its total mineral resources and a 75% rise in its
attributable mineral reserves for the year to December 2009.

Chief executive Mark Bristow said this significant escalation again
underlined the effectiveness of the company's key strategy of achieving
organic growth through exploration success, and of creating value
through the development of profitable mining projects. He cited the
recent discoveries of Gounkoto and Massawa, and the rapid expansion of
Kibali's resources and reserves since its acquisition late last year,
as major contributors to the increased size and enhanced quality of the
Randgold asset base.

Randgold's annual resource and reserve declaration published as part of
its 2009 annual report today, shows that at the attributable level,
measured, indicated and inferred resources rose from 16.13 million
ounces to 27.33 million ounces over the year. This is mainly
attributable to the delineation of new resources at Gounkoto and the
acquisition of a 45% stake in Kibali. Attributable proved and probable
reserves grew from 8.87 million ounces to 15.56 million ounces, largely
due to the conversion of resources to reserves at Gounkoto and Massawa,
an increase in ownership from 84% to 89% of the Tongon project, and the
sharp rise in Kibali's reserves."When we acquired Kibali in October, its
probable reserves stood at 5.5 million ounces. By the year end, our team
had grown this to 9.3 million ounces, demonstrating our ability to add
value through continued exploration," Bristow said."Excluding Morila, which
is no longer an operating mine, the average grade of our reserves is now
above 4 g/t, and Gounkoto, Massawa and Kibali are all high-grade projects.
We are not only increasing the size but improving the quality of our
assets. It's also worth noting that we haven't used the higher gold price
to boost our reserves - they've been calculated at a conservative US$700
per ounce gold price and a higher cost profile, while the resources have
been estimated at US$1 000 per ounce. This is real growth, framed within
realistic parameters and a viable business plan."

ABOUT RANDGOLD:

Randgold Resources is an African focused gold mining and exploration
company with primary listings on the London Stock Exchange and Nasdaq.
Major discoveries to date include the Morila deposit in southern Mali,
the Yalea deposit and the Gounkoto deposit, both in western Mali, the
Tongon deposit in the Cote d'Ivoire and the Massawa deposit in eastern
Senegal.

Randgold Resources financed and built the Morila mine which since
October 2000 has produced more than 5.5 million ounces of gold and
distributed more than US$1.5 billion to stakeholders. It also financed
and built the Loulo operation which started as two open pit mines in
November 2005. Since then, an underground mine has been developed at
the Yalea deposit and construction of a second underground operation is
underway at the Gara deposit. First gold production from the company's
new mine being developed at Tongon is scheduled for the fourth quarter
of 2010.

Randgold's current major projects are Gounkoto on the Loulo permit in
Mali, Massawa in Senegal and Kibali in the Democratic Republic of the
Congo. In 2009 the company acquired a 45% interest in the Kibali
project, which now stands at 9.2 million ounces of reserves and is one
of the largest undeveloped gold deposits in Africa. Randgold also has
an extensive portfolio of organic growth prospects, which is constantly
replenished by intensive exploration programmes in Burkina Faso, Cote
d'Ivoire, DRC, Mali and Senegal.

factors and events that are not within the control of Randgold and
there is no assurance they will prove to be correct. Forward-looking
statements are subject to known and unknown risks, uncertainties and
other factors that may cause the actual results, level of activity,
performance or achievements of Randgold (including Kibali) to be
materially different from those expressed or implied by such

acquisition of 10 per cent of the issued capital of Kibali Goldmines
SPRL. Although Randgold has attempted to identify important factors
that could cause actual results to differ materially from those

accurate, as actual results and future events could differ materially
from those anticipated in such statements. Accordingly, readers should
not place undue reliance on forward-looking statements. Randgold does
not undertake to update any forward-looking statements herein, except
in accordance with applicable securities laws. CAUTIONARY NOTE TO US
INVESTORS: the SEC permits companies, in their filings with the SEC, to
disclose only proven and probable ore reserves. We use certain terms
in this release, such as 'resources', that the SEC does not recognise
and strictly prohibits us from including in our filings with the SEC.
Investors are cautioned not to assume that all or any parts of our
resources will ever be converted into reserves which qualify as 'proven
and probable reserves' for the purposes of the SEC's Industry Guide
number 7.
