Gold Fields Limited’s Gruyere Gold Mine Fully Certified Under International Cyanide Management Code

The International Cyanide Management Institute (ICMI) announced today that Gold Fields Limited’s Gruyere Gold Mine in Australia has been certified in full compliance with the International Cyanide Management Code (Cyanide Code).

The Gruyere Gold Mine was audited using ICMI’s Pre-operational Verification Protocol prior to the start of gold production and was conditionally certified in April 2019. As required under the Cyanide Code, the mine was audited against ICMI's operational Verification Protocol by independent professional third-party auditors within one year of its first use of cyanide. ICMI has received and accepted the auditors’ Detailed Audit Findings Report, which found the Gruyere Gold Mine in full compliance with the Cyanide Code's Principles and Standards of Practices. The Summary Audit Report and Auditor Credentials Form are available on Gold Fields’ Signatory Page on the Cyanide Code website: The operation must be re-audited every three years to evaluate continuing compliance with the Cyanide Code.

The Cyanide Code is amongst the most established certification programs in the mining sector.  This voluntary industry program is focused on the safe management of cyanide by companies producing gold and/or silver and by companies producing and transporting cyanide. It was developed under the aegis of the United Nations Environment Programme by a multi-stakeholder Steering Committee. The Cyanide Code is intended to promote and help ensure the safe and environmentally responsible management of cyanide used within the gold and silver mining industries. Operations are assessed for compliance triennially by qualified, independent auditors. 

ICMI has been established to administer the Cyanide Code, promote its adoption, evaluate its implementation, and manage the certification process for operations using, producing and transporting cyanide. A detailed list of the operations covered by signatory companies' applications, along with the full text of the Cyanide Code and its implementing and administrative documents, are available at We invite you to read our 2019 Annual Report, which can be viewed here.
