MMG Case study - MMG production was highly impacted by unreliable power from grid - In end 2012 Aggreko and MMG entered in formal agreement for a 12MW/33KV power plant in continuous and 4MW/33 KV in standby, all diesel powered - End of 2013 this agreement has been extended to a further 8 MW/33 KV diesel to reach a total of 24 MW capacity. The entire power is planned to run at least up to end 2015. - This capacity can be ramp up of down depending of quality of power from grid MMG Kinsevere DRC production Report Energy delivery August 2014 PLANT NUMBER PLANT 1 PLANT 2 PLANT 3 POWER PER PLANT 0 TO 12 MWH 12 TO 16 MWH EQUIVALENT RUNNING HOURS NUMBER OF RUNNING HOURS 16 TO 24 MWH >24 MWH <14.47 PER HOUR >14.47 PER HOUR >24 MWH LUMP SUM 1858.898 1.056 EXTRA $ N/A 15 150 Total Production MWh 5059.908 Fuel Consumption August 2014 Total Fuel (Liters) Fuel rate L/MWh 1363830 269.537

MMG: testimonial MMG request that Aggreko maintain a minimum of 5 generators on line in order to keep power to the site following a trip of the utility supply. Load shedding disconnects the main productive loads at these times and retains light & power to the plant. There is a significant SAFETY benefit in keeping the lights on after these outages. This also allows a restart of the plant very quickly after an outage. Aggreko power is used initially with a swap over to utility power as soon as it becomes available. The ability of the Aggreko station to synchronise additional generators immediately following an outage certainly allows us to ramp up the power draw and get back to producing copper. The primary benefit where production is impacted is any time that Aggreko operates more than these first 5 sets. All MWh produced by these extra generators will be utilised to produce copper. A conservative estimate of copper produced would be one tonne of copper for every 3MWh. The cash flow impact for Kinsevere would be approximately 50% of the LME price for this extra copper produced Donald Stevens Senior Electrical engineer MMG Kinsevere

Sum up, Q&A - Reliable power generation is critical for mining companies - Uncertainty on power quality and availability from grid and import - Issues of grid are temporary - You are expert in mining, not power producers - Aggreko is the world and DRC leader for this type of services Q&A
