Centerra is a signatory of the International Cyanide Management Code (the Cyanide Code or ICMI). The Cyanide Code focuses exclusively on the safe management of cyanide that is produced, transported and used for the recovery of gold and silver. Certification under the Cyanide Code includes requirements related to financial assurance, accident prevention, emergency response, training, public reporting, stakeholder involvement and verification procedures.
Kumtor has been independently certified and audited for its transportation practices under the Cyanide Code. Kumtor’s most recent certification was in December 2018 and is valid for a three-year period.
In June 2020, Öksüt became a signatory of the Cyanide Code. As prescribed within the Cyanide Code, Öksüt will complete the verification and audit process within three years of the certification date.
In 2020, Öksüt completed a Cyanide Code gap analysis and, in 2021, will begin working toward ICMI certification.
Effluents and Wastewater
We design our sites to manage and minimize the impact of effluents on the environment.
At Kumtor, we recognize that the main wastewater concerns of our communities are related to cyanide. Industrial wastewater, containing residual cyanide, is a component of tailings slurry. The suspended sediment is left in the TSF, and the resulting water is treated at the effluent treatment plant (ETP) prior to release into the environment.
