Resolute Mining has taken the roaster offline at its Syama gold mine in Mali, due to a crack being detected in the main external shell.
The company believes the repair to the crack may have an impact on Syama’s sulphide circuit production during the December 2019 quarter.
The roaster, which is a key component of the sulphide processing circuit, is currently being cooled down, so Resolute can assess the full extent of the damage and identify what repair work is needed.
During September, roaster refractory lining and sulphide crusher apron feeder underwent repair work.
After the repairs, Resolute successfully brought the roaster back into service and it was expected to operate normally.
However, upon reheating and under operation loads, a crack unrelated to the September maintenance and repair work was discovered.
Resolute will investigate the full impact the roaster shutdown will have for the remainder of the quarter once they have put a repair plan in place.
The company produced 103,201 ounces of gold across its operations during the September quarter, with the Syama site contributing 45,804 ounces to this total.
