3. Case Study – Copper/ Gold Mine, Horn of Africa
 TSX listed junior miner with its’ main
project in the Horn of Africa
 The executive board were looking for a
way of providing 20MW uninterruptable
power for the mine on OpEx not CAPEx.
 An Evaluation was made between diesel
and HFO which resulted in a decision to
rent a diesel plant for an initial period of
2 years.
 The contract was extended to 10 years once the rental model had been
proven.
 MCD assisted in the evaluation and decision making process with the
clients’ EPCM contractor
 The decision to rent a mobile plant has saved the client in excess of $100m
over the life of the mine.

4.  MCD lead the mine tendered for
a new power plant, a fuel
storage facility and fuel supply
contract.
 EPCM of 5MW HFO power
plant and 460,00L fuel storage
facility

~$2.5m.
Case Study –Tanzania
 London listed emerging gold producer in Tanzania.
 Their flagship project, has been producing gold since 2012.
 The back of mine cost , mainly from fuel cost for the diesel fired power
plant was creating barriers to development of the mine.
 MCD carried out a high level economic and technical study of the current
power plant and to recommend a new solution that would save around 30%
of the fuel cost.

5. Case Study – Tanzania
 In addition a Solar PV test farm has been added to the mini grid operating at
the mine.
 The initial cost of power was $0.43/ kWh
 With the change to heavy fuel oil this drops to $0.33 cents
 By further introducing the Solar PV farm the cost during daylight hours drops
by an additional $0.03-0.04 per KWh.
