We have a background in simple process (gravity and CIL) operations
We’ve developed processing using flotation and ultra-fine grind for more complex materials
We’re “owner builders”
We’ve built 5 mines with +$5bn capital investment.
We staff up with specific skills (as needed) and shrink with project completion

Randgold reports its mineral resources and mineral reserves in accordance with the JORC 2012 code. As suchnumbers are reported to the second significant digit. They are equivalent to National Instrument 43-101. Mineralresources are reported at a cut-off grade based on a gold price of US$1 500/oz.The reporting of mineral reserves is also in accordance with Industry Guide 7. Pit optimisations are carried out at agold price of US$1 000/oz, except for Morila which is reported at US$1 300/oz. Mineral reserves are reported at acut-off grade based on US$1 000/oz gold price within the pit designs. Underground reserves are also based on agold price of US$1 000/oz. Dilution and ore loss are incorporated into the calculation of reserves.
Cautionary note to US investors: The United States Securities and Exchange Commission (the SEC) permitsmining companies, in their filings with the SEC, to disclose only proven and probable ore reserves. Randgold usescertain terms in this annual report such as ‘resources’, that the SEC does not recognise and strictly prohibits thecompany from including in its filings with the SEC. Investors are cautioned not to assume that all or any parts ofthe company’s resources will ever be converted into reserves which qualify as ‘proven and probable reserves’ forthe purposes of the SEC’s Industry Guide number 7.

Forward-looking statements include, but are not limited to, statementswith respect to the future price of gold, the estimation of mineral reserves and resources, the realisation of mineralreserve estimates, the timing and amount of estimated future production, costs of production, reservedetermination and reserve conversion rates. Generally, these forward-looking statements can be identified by theuse of forward-looking terminology such as ‘will’, ‘plans’, ‘expects’ or ‘does not expect’, ‘is expected’, ‘budget’,‘scheduled’, ‘estimates’, ‘forecasts’, ‘intends’, ‘anticipates’ or ‘does not anticipate’, or ‘believes’, or variations ofsuch words and phrases or state that certain actions, events or results ‘may’, ‘could’, ‘would’, ‘might’ or ‘will betaken’, ‘occur’ or ‘be achieved’. Assumptions upon which such forward-looking statements are based are in turnbased on factors and events that are not within the control of Randgold Resources Limited (‘Randgold’) and thereis no assurance they will prove to be correct. Forward-looking statements are subject to known and unknownrisks, uncertainties and other factors that may cause the actual results, level of activity, performance orachievements of Randgold to be materially different from those expressed or implied by such forward-lookingstatements, including but not limited to: risks related to mining operations, including political risks and instabilityand risks related to international operations, actual results of current exploration activities, conclusions ofeconomic evaluations, changes in project parameters as plans continue to be refined, as well as those factorsdiscussed in Randgold’s filings with the US Securities and Exchange Commission (the ‘SEC’). Although Randgoldhas attempted to identify important factors that could cause actual results to differ materially from those containedin forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated orintended.
