Kibali…history

1903… First gold discovery in the territory of a local chief named Kilo

by Australian prospectors Hannan and O’Brien, working under direction of

the Government of the Independent State of Congo

1904… Beginning of gold production in north eastern DRC

1905 – 1906… Gold discovery to the northwest in the gravel beds of Moto River

1926… Organisation created by Belgian Government to operate these deposits

became la Société des Mines d’Or de Kilo-Moto

1950’s… Annual production culminates to about 9 tons of fine gold

After 1960: Gold production plummeted

1966… The name of the Société was changed to Office des Mines d’Or de Kilo-

Moto or OKIMO

Since 1990… Annual production less than 100 kg of gold. Total recorded historic output

of the region comes to 350 tons

1998… Barrick and AngloGold in JV over project area, discovery of Kibali deposit

2002… New attractive Mining Code in place, with the baking of the World Bank

2004… Moto Goldmines acquires the Kibali Project and discover main KCD

deposit and define ~20Moz

2009… Randgold Resources and Anglogold Ashanti acquire Moto Goldmines

and the Kibali Project

2012… Development of Kibali starts

2013… First gold poured on 24th September and commercial production commenced in

October

Hydrothermal alteration consists of: ankerite + later siderite + quartz + sericite

Sulphide assemblages include: (1) early pyrrhotite + arsenopyrite; (2) pyrite +/- Cu phases and gold; (3) later second generation pyrrhotiteand skeletal pyrite

Kibali…building value through Integrated Geology and MRM

Acquired total mineral resource inventory of 22.0Moz from Moto (2009), 5.5Moz reserves

Completed mapping, re-logging of core, drilling of key oriented holes, developed geologic models, updated resource models and applied economic criteria

Inventory reduced to 18.9Moz but increased reserves to 10.9Moz (2012)

Inventory increased by 2.5Moz to 21.5Moz (Q2 /’13)

Excluding 1.1Moz low grade Kibali South (to Sokimo)

New geologic model being used to prepare new mining model and update reserves

with respect to the future price of gold, the estimation of mineral reserves and resources, the realisation of mineral reserve estimates, the timing and

amount of estimated future production, costs of production, reserve determination and reserve conversion rates. Generally, these forward-looking

statements can be identified by the use 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 of such words and phrases or state that

certain actions, events or results ‘may’, ‘could’, ‘would’, ‘might’ or ‘will be taken’, ‘occur’ or ‘be achieved’. Assumptions upon which such forward-looking

forward-looking statements, including but not limited to: risks related to mining operations, including political risks and instability and risks related to

international operations, actual results of current exploration activities, conclusions of economic evaluations, changes in project parameters as plans

continue to be refined, as well as those factors discussed in Randgold’s filings with the US Securities and Exchange Commission (the ‘SEC’). Although

Randgold has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking
