Centerra halts gold bullion production in Öksüt after mercury detected at recovery plant


The Canada-based gold miner said it was also evaluating several potential technical solutions to remove mercury from the gold recovery process, including a retort and wash system in the ADR plant, ahead of the restart of production.

The Öksüt mine became Centerra’s third operating mine in January 2020 when it dumped its gold. Approximately 28.2 million tonnes of ore grading 1.3 g/t gold, containing a total of 1.2 million ounces, are expected to be mined and stockpiled over an eight-year mine life.

Despite the temporary suspension, the Öksüt mine continues to extract ore, stockpile the ore on the leaching platform and process the ore in the ADR plant in the form of gold in the form of carbon.

The carbon gold will be stored until the electrowinning process is restarted, where recovery of the gold from concentrated solution occurs, the company said.

Centerra will also assess the impact of this suspension on its guidance for 2022, which was raised to 400,000-450,000 ounces earlier in the year.

He notes that until March 17, the Öksüt mine produced and sold more than 54,000 ounces of gold. The mine is expected to contribute between 210,000 and 240,000 ounces in 2022.

Centerra Gold shares fell 3.9% at 12:10 a.m. ET Friday. The company has a market cap of C$3.6 billion.
