Marigold Mining Company’s Marigold Mine Achieves Sixth Certification Under the International Cyanide Management Code

The International Cyanide Management Institute (ICMI) announced today that the Marigold Mining Company’s Marigold Mine, located in the United States, has been recertified in full compliance with the International Cyanide Management Code (Cyanide Code). This is the Marigold Mine’s sixth certification in full compliance under 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 Marigold Mine was initially certified in full compliance with the Cyanide code in January 2007 and was the first operating mine to be certified under the Cyanide Code. The Marigold Mine was recertified in January 2010, March 2013, February 2016, and November 2018. As required under the Cyanide Code, the mine was again audited against the ICMI’s Mining Verification Protocol by an independent professional third-party auditor within three years of its previous certification. ICMI has received and accepted the auditor’s Detailed Audit Findings Report, which found that the Marigold Mine had maintained full compliance with the Cyanide Code’s Principles and Standards of Practices since its previous certification. The Summary Audit Report and Auditor Credentials Form are available on Marigold Mining Company’s 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 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 We invite you to read our 2020 Annual Report, which can be viewed here.
