INCREASING RESERVES AND UPPING GRADE, RANDGOLD BUCKS INDUSTRY TREND AGAIN

London, 28 March 2013 - Randgold Resources increased its attributable reserves in 2012, despite their depletion from mining in a year that delivered record production. At the same time, the company continued to improve its overall reserve grade.

Randgold's annual mineral resource and reserve declaration, published today as part of its annual report for 2012, shows total attributable mineral reserve ounces up by 803000 to 16.36 million. In line with the company's focus on quality over quantity, the group reserve grade was increased from 3.84 to 3.87g/t, while total attributable resources were down from 28.25 to 27.21 million ounces.

Randgold's general manager evaluation Rod Quick noted that the grade improvement had been driven principally by the group's flagship Loulo, Gounkoto and Kibali deposits."This ability to add quality ounces from extensions to our known orebodies and to continue converting ounces from the inferred to the indicated category shows the value of our strategy of focusing on world class deposits," he said."It's also worth noting that we haven't used the higher gold price to boost our ounces. For the second year running, we have calculated our reserves at a relatively conservative US$1000/oz of gold while our resources have been estimated at US$1500/oz."

At Kibali, the giant gold mine Randgold is developing in the Democratic Republic of Congo, total reserves now stand at 10.92 million ounces at 4.10g/t, up from 10.21 million ounces at 4.04g/t, as a result of grade control drilling in the KCD pit and extension drilling of the 5000 Underground Lode. At Loulo in Mali underground reserves have increased by 90000 ounces despite mining depletion, principally as a result of grade increases around the Yalea 'purple patch' as well as at Gara. The neighbouring Gounkoto open pit mine reported lower reserves, due to mining depletion, but with a significant grade improvement. The incorporation of the low grade Faraba pit into the total Gounkoto reserves caused a lowering of the overall Gounkoto reserve grade from 5.06g/t to 4.73g/t. However the quality of the Gounkoto underground mineral resource improved significantly with grade increasing from 4.66g/t to 6.43g/t and bodes well for the generation of further high grade reserves post the completion of the underground feasibility study. In Cote d'Ivoire, Tongon's resources and reserves as well as the grade were impacted negatively by the mine's underperformance in 2012. With last year's operational problems now under control, however, the mine should be able to drive recoveries up and costs down, which should result in an increase in reserves.

Chief executive Mark Bristow said while the gold mining industry in general was decreasing the grade at which it mined in order to maintain production profiles, and thus intensifying cost pressures, Randgold was able to replace its depleted ounces at a higher grade. "The measure of a gold mining company's value is not only its resource and reserve base, but also the way in which it invests in the future. Randgold is strategically well positioned, with a substantial portfolio of quality greenfields prospects. We continue to explore aggressively across West and Central Africa's most prospective gold belts. We're also looking to expand our footprint there through joint ventures with junior exploration companies, some of whom hold good assets but are unable to develop them in a stressed market," Bristow said.

Randgold reports its mineral resources and mineral reserves in accordance with the JORC code and are equivalent to National Instrument 43-101. The reporting of ore reserves is also in accordance with SEC Industry Guide 7. Open pit mineral resources consist of insitu mineral resources at a 0.5g/t cut-off falling within a US$1 500/oz optimised pit shell. Underground mineral resources are those mineral resources falling below the open pit resources reported at cut-off grades of between 1.5g/t to 2.0g/t. Open pit and underground mineral reserves are economic at a gold price of US$1 000/oz, except for the Morila pit which is calculated at a gold price of US$1 300/oz. Open pit reserves are calculated at a weighted average cut-off grade of 1.08g/t. Our underground reserves are calculated at a weighted average cut-off grade of 2.34g/t. Our stockpile reserves at Morila are calculated at a cut-off grade of 0.68g/t. Dilution and ore loss are incorporated into the calculation of reserves. Addition of individual line items may not sum to sub totals because of the rounding off to two decimal places. Mineral resources are inclusive of mineral reserves.

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.
