Resolute Mining Limted (ASX:RSG) (LON:RSG) has successfully recommissioned the sulphide circuit following successful repairs at its Syama Gold Mine in Mali.
The roaster and all aspects of the Syama sulphide circuit are performing as expected and Resolute’s fully autonomous haulage fleet is now commissioned and operational.
More than 400,000 tonnes of high-grade underground ore is now available on the run-of-mine pad.
The available stockpile of underground ore ensures that sulphide processing operations will be unconstrained by ore availability during 2020 and provides greater confidence in achieving targeted throughput.
Completed efficiently and safely
Resolute’s managing director John Welborn said: “The roaster repairs and associated unscheduled sulphide circuit maintenance has been a complex project which has been successfully completed efficiently and safely.
“I congratulate our project, technical and operating teams at Syama for their success in this herculean task and for the exceptional response in delivering a solution to our requirements.
“The Syama sulphide circuit is now fully operational and ready to demonstrate our ambitions at Syama by delivering strong stable recoveries from consistent ore feed from the Syama Underground Mine.
“The significant ore stockpiles we now have available will allow us to focus on cost efficiencies with our autonomous underground mine systems rather than requiring a focus on maximising mined and hauled tonnages.
Focused on expanding the mine in 2020
“During 2020, we intend to investigate opportunities to expand both the underground mine production capacity, and the processing capacity of the sulphide circuit, beyond the current nameplate of 2.4 million tonnes per annum.
“The crack to the roaster, and the required unscheduled sulphide circuit downtime, has resulted in a material loss in production from the Syama sulphide circuit in the December 2019 quarter.
“However, we have worked hard to offset this lost production from other production sources and complete the repairs as quickly as possible.
Production guidance remains 400,000 ounces
As a result, the material loss in sulphide production is likely to have only a minor impact on overall Group production and targeted FY19 production guidance at 400,000 ounces of gold.
“The lost production in 2019 is more than offset by the additional production we now expect to gain in 2020 by the deferral of the next major roaster shutdown to early 2021.”
