Resolute Mining Ltd. said Dec. 10 that it completed the repairs to the sulfide roaster within the allotted time and budget at the Syama gold mine in Mali and has started reheating the roaster ahead of resuming normal operations.
The Australia-listed miner temporarily suspended the roaster in early October due to a crack in its main external shell. The roaster is a key component in the company's sulfide processing circuit at the Syama mine. The repair program also fixed a crack in the primary cyclone and two minor cracks on the main roaster body.
The repairs included extensive refurbishment to the roaster and new installations. The refurbishments could allow Resolute to defer a scheduled May 2020 shutdown up to January 2021, depending on the roaster's operational performance after reheating.
In June, Resolute achieved commercial production at Syama. Despite the roaster shutdown, the miner maintained its full-year 2019 gold production guidance for Syama at 400,000 ounces in October.
