Aggreko commissions Yanfolila diesel power plant

less delivery of power. Aggreko is offering a complete turnkey solution on a seven- year contract. Yanfolila – which has a capex of US$79,4 million – will recover 770 koz of gold from five pits over an initial eight-year mine life, with the average annual production being 107 000 oz a year. Production in year 1 will be 132 000 oz. Assuming a gold price of US$1 250/oz, all-in sustaining costs are estimated at US$695/oz. The gravity/CIL plant, which is being built by South Africa’s SENET, has a 1,24 Mt/a capacity. Pre-production mining by mining con- tractor AMS began in August this year. AMS is deploying a fleet which includes four Liebherr 9150 excavators, one Liebherr 9250 excavator and 18 Cat 777F dump trucks. 

AIM-listed Hummingbird Resources has reported that Aggreko has fully commis- sioned the 7,4 MW diesel power facility on site to provide power to the process plant at the company’s Yanfolila gold mine in Mali. “Working with Aggreko to deliver our power remains in line with our strategy of working with world class partners as we progress Yanfolila towards imminent gold production,” comments Dan Betts, CEO of Hummingbird. “Aggreko offers the best quality power solution in the market at competitive pricing with a full team on site to run and maintain its operations. “Furthermore, we continue to evalu- ate potential renewable solutions such as solar PV, as we strive to be a responsible miner operating for the benefit of all our stakeholders.

“We expect the next upcoming mile- stone to be the commissioning of the water supply and testing the now fully installed mill.” Adds James Shepherd, Managing Director, Africa of Aggreko: “Our people in Yanfolila and the wider Aggreko team are dedicated to supporting Hummingbird towards the success of this project. “Getting reliable, efficient and cost- effective power supply is critical when it comes to mining operations. Aggreko’s technologies provide a scalable and effi- cient power that can accommodate any change of needs and resources available.” The installed power at Yanfolila is pro- vided through a series of 1 MW units.
