Resolute Mining has completed an equipment repair job at the Syama gold mine in Mali, West Africa that involved 200 personnel from 22 countries at peak.
The repair concerned Resolute’s sulphide roaster, which is a key component of the sulphide processing circuit at Syama.
Resolute took the roaster offline in early October after detecting a crack in the main external shell.
The company expects to commence concentrate feed in about five days’ time.
Resolute managing director and chief executive John Welborn was pleased the roaster repair was completed safely, on time and within budget.
“I am delighted and proud that we have successfully executed the repairs to the Syama sulphide roaster,” Welborn said.
“We are now reheating the roaster and expect to shortly return the sulphide circuit to full operational capacity.”
The repair program consumed a total of 127,344 man-hours and required five cranes, 21 welding machines, seven items of heavy mobile plant, 64 procurement packages and 19 construction packages.
These go on top of 12 services packages, 25 tonnes of boiler plate, 45 tonnes of scaffold, 60 tonnes of refractory, 27 air cargo packages and two dedicated cargo aircraft.
During the repair, Resolute refurbished the roaster extensively with a new secondary cone crusher installed, along with chute improvements, relining of sulphide primary mill and refurbishment of the sulphide grinding circuit.
Resolute hopes that the comprehensive refurbishments will defer the scheduled roaster shutdown from May 2020 to January 2021.
“We remain committed to delivering on our ambitions at Syama by delivering stable long-life, low-cost production from the Syama underground mine,” Welborn said.
“With significant ore stockpiles now available we are preparing for a highly productive period at Syama during 2020.”
