CyPlus Idesa Cyanide Production Plant Recertified Under the International Cyanide Management Code

The International Cyanide Management Institute (ICMI) announced today that CyPlus Idesa’s cyanide production plant in Mexico has been recertified in full compliance under the International Cyanide Management Code (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.

CyPlus Idesa’s production plant was pre-operationally certified under the Cyanide Code in March 2016 and was operationally certified in full compliance in May 2017 and again in July 2020. The operation was again audited against ICMI’s Production Verification Protocol within three years of its certification by an independent professional third-party auditor. ICMI has received and accepted a Detailed Audit Findings Report and a Summary Audit Report which found that the CyPlus Idesa cyanide production plant had maintained full compliance with the Cyanide Code’s Production Principles and Standards of Practice since its previous certification audit. The Summary Audit Report and Auditor Credentials Form are available on CyPlus Idesa’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 2022 Annual Report, which can be viewed here.
