Kinross Gold Corporation’s Round Mountain Mine Achieves Seventh Certification Under the International Cyanide Management Code

The International Cyanide Management Institute (ICMI) announced today that Kinross Gold Corporation’s Round Mountain Mine, located in the United States, has been certified in substantial compliance under the International Cyanide Management Code (Cyanide Code). This is the Round Mountain Mine’s seventh certification under the Cyanide Code, representing 19 years of continuous certification.

The Round Mountain Mine was initially certified in full compliance under the Cyanide Code in May 2007, and was recertified in September 2010, in January 2014, in March 2017, in March 2020, and in May 2023. As required under the Cyanide Code, the mine was again audited against ICMI’s Mining Operations Verification Protocol by independent professional third-party auditors within three years of its previous certification. ICMI has received and accepted the auditors’ Detailed Audit Findings Report and Summary Audit Report, which found Round Mountain in substantial compliance with the Cyanide Code’s Principles and Standards of Practice. The Summary Audit Report, Corrective Action Plan, and Auditor Credentials Form are available on Kinross Gold Corporation’s Signatory Page on the Cyanide Code website. The operation can be fully certified once it has implemented its Corrective Action Plan and achieved full compliance with the Cyanide Code. The operation must be re-audited every three years to evaluate continuing compliance with the Cyanide Code.

The Cyanide Code is a voluntary industry program focused on the safe and environmentally responsible management of cyanide by companies producing gold and/or silver and by companies manufacturing, warehousing, and transporting cyanide. The Cyanide Code was developed under the aegis of the United Nations Environment Programme by a multi-stakeholder Steering Committee and is amongst the most established certification programs in the mining sector. The Cyanide Code is intended to complement an operation’s existing obligation to comply with the applicable laws and regulations of the political jurisdiction in which the operation is located.

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 www.cyanidecode.org.
