Because much of the ore that Kinross mines contains highly disseminated, low concentrations of gold, the use of aqueous chemical extraction processes is the only economically viable method for extracting the gold from the ore. The most efficient and environmentally safe reagent available for the dissolution and extraction of gold is cyanide. However, because of its hazardous characteristics, the use and management of cyanide requires stringent control at all times, from transportation to disposal.
Recognizing the importance of maintaining the highest standards of cyanide management, Kinross was one of 14 initial signatory companies to the International Cyanide Management Code (ICMC) in 2005. The Cyanide Code requires on-site verification by an independent third-party auditor for initial certification and recertification every three years thereafter, as well as ongoing monitoring and annual reporting. Compliance with the Cyanide Code is a key part of Kinross’ commitment to protect our workers, communities, and the environment in which we operate.
In 2013, we received certification at Chirano. Recertification has also been achieved at Paracatu and Maricunga in 2012, and Kupol and Kettle River-Buckhorn in 2013. All new facilities are being built to meet the requirements of the Cyanide Code. Tasiast is Kinross’ only remaining site to be certified, and it is advancing toward audit, which is expected in 2015.
