Opencast mining…

Multiple pits to be mined over 10 years

KCD pit mining started in July 2012

Production achieved with trained local operators

3 x Liebher 9350 diggers , 1 x Liebher 984 digger and 19 x 777G dedicated to production and auxiliary equipment as support

The mine plan, including ore production and plant feed, was achieved for the year

Overview

Underground Mine Complex…Shaft

A 760m shaft, 8m diameter concrete lined

Shaft capacity Wet tonnes(includes 5% moisture) = 3.6Mt/yr.

Shaft capacity Dry tonnes = 3.43Mt/yr.

Average tonnage hoisted from the shaft on current schedule = 3Mt/yr.

Dedicated hoisting shaft but it will be equipped with a service cage for maintenance purposes

Material Handling and Orepass

Nine orepasses feeding onto a haulage drive

Automated loader feeding from orepasses to crusher

2 sets of crushers underground with 1000 t capacity for coarse and fine bin each.

Paste Plant

Paste plant with 192 m3/hr capacity

Full flexibility in throughput and binder content

Construction started and planned for commissioning in April 2015

Underground mining…vertical shaft

Shaft current depth 720m

83 days ahead of schedule

Development ongoing on last level close to main infrastructure

Target to finish sinking in Q3 2015 and equip in Q1 2016

Decline Development

Decline development started in Dec 2012 with Byrnecut as contractor

Byrnecut consistently achieving the development targets

Rate of advance has been materially better than planned in the feasibility

An average of 300m/month/jumbo was reached in development, with the decline contractor has now ramped up to 900m/month

A total of 12.1km was developed project to date of which 10km in the capital side and 2 km in opex

For 2014 a total of 8km was developed of which 6km in capital and 2 km in opex

Production started from the first stope in Dec 14

Target from stoping is 30Kt/month from Q1 to Q3

Stoping tonnes ramp up to 70Ktonnes/month in Q4

Hydropower

Our power strategy…

Supply concept is a hybrid arrangement

Peak power Deliver peak power on the available river schemes average flows

Dry season low flow powerMaximize the number of stations supplying to maximize the power available in the low flow periods.

Diesel back-up generationFor power load fluctuations of shaft winder and Met PlantInitially provide dry season make-up power from high speed diesel unitsSubstitute (diesel generation) with more hydro stations as overall power demand grows

Project Update

Investment phases…

Phase 2 capital programme is estimated at US$700m before escalation provisions and contingencies which will run concurrently with Phase 1 but will extend over a longer period, is focused primarily on the underground development and includes a twin decline and vertical shaft system as well as three hydropower stations. This is expected to bring the underground into first production by the end of 2014, with vertical shaft handover scheduled in 2017.

Phase 1 capital programme is estimated at US$1130m and will cover the metallurgical facility, one hydropower station and back-up thermal power facility, construction of the tailings storage facility, relocation of villages, open pit mining and all shared infrastructure. This is expected to be completed by December 2014.

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 noteto US investors: The United States Securities and Exchange Commission (the SEC) permits mining companies, intheir filings with the SEC, to disclose only proven and probable ore reserves. Randgold uses certain terms in thisannual report such as ‘resources’, that the SEC does not recognise and strictly prohibits the company fromincluding in its filings with the SEC.
