Resolute Mining expects the damaged sulphide roaster at the Syama gold mine in Mali to be fully operational by early to mid-December after it was taken offline during October.
The company is collaborating with the designer of the original roaster (Outotec) to repair a crack in the main external shell of the processing circuit’s key component.
Repairs are on schedule and within budget, with the company completing the installation of a secondary steel shell to the defective area where the roaster cracked.
Despite the roaster being out of operation for most of the month, Resolute poured 42,365 ounces of gold in October.
This, along with strong contributions from its Tabakoroni open pit mine, Mako and Ravenswood gold mines, has enabled Resolute to maintain its company-wide 2019 guidance of 400,000 ounces.
The Syama operating team was able to offset lost production from the cracked roaster by processing stockpiled transitional oxide material through the sulphide circuit carbon in leach infrastructure.
With the roaster offline, the Mali mine has been focussing on drill stocks, draw point development and automation optimisation, while still continuing to accelerate production.
Resolute believes the roaster downtime is providing the opportunity to accumulate more than 300,000 tonnes of available underground ore on the run-of-mine pad.
“The roaster downtime is affecting what would otherwise be a highly productive period for Resolute as we ramp-up the Syama underground mine,” managing director and chief executive officer John Welborn said.
“We are working hard to repair the Syama roaster and are committed to delivering on our ambitions at Syama by delivering stable, long-life, low-cost production form the mine.”
