Cyanide Management

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.

As a signatory to the ICMC, Öksüt successfully completed stage 1 and stage 2 of its environmental and safety management systems (ISO 14001 & ISO 45001) audit in 2021. After receiving the related certificates and flags, Öksüt is working towards ICMC certification by the end of 2023.

Air Quality

Our teams continuously monitor for the potential impacts of our operations and activities on air quality. We understand the detrimental impacts that air pollution can have on human health and ecosystems, and work to actively mitigate these risks.

Fugitive dust control and mitigation measures may include road and stockpile watering; ambient air monitoring such as meteorological monitoring, dust fall monitoring and fine particulate monitoring; use of dust control agents; and revegetation of disturbed or exposed areas.

Dust suppression watering is the primary control and mitigation of fugitive dust for on-site roadways. In 2022, water at Mount Milligan Mine was regularly drawn from the tailing storage facility (TSF) and applied to haul roads within the TSF footprint on an as needed basis. At our Öksüt Mine, we have implemented appropriate control measures wherever the potential for fugitive dust generation is significant, including soil stockpiles and highly trafficked roads, and especially for activities near sensitive receptors.
