Asahi Kasei Corporation’s Cyanide Production Facility Certified Under International Cyanide Management Code

The International Cyanide Management Institute (ICMI) announced today that Asahi Kasei Corporation’s Mizushima Works sodium cyanide production facility in Okayama Prefecture, Japan has been certified in full compliance with the International Cyanide Management Code (Cyanide Code).

ICMI has received and accepted a Detailed Audit Findings Report prepared by an independent professional third-party auditor who evaluated Asahi Kasei’s Mizushima Works sodium cyanide production facility against ICMI’s Cyanide Production Verification Protocol and found it in full compliance with the Cyanide Code’s Principles and Production Practices. The Summary Audit Report and Auditor Credentials Form are available on the Cyanide Code web site on Asahi Kasei Corporation’s Signatory Companies Page: 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 for companies involved in the production of gold and/or silver using cyanide and companies producing and transporting that 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 complement an operation’s existing obligation to comply with the applicable laws and regulations of the political jurisdictions 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. 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
