Newcrest’s Gosowong Mine and PT Nusa Halmahera Minerals’ Gosowong Mine Supply Chain Recertified Under International Cyanide Management Code

The International Cyanide Management Institute (ICMI) announced today that Newcrest Mining Ltd.’s Gosowong Mine in Indonesia and the PT Nusa Halmahera Minerals (PT NHM) Supply Chain that transports cyanide to the Gosowong Mine have been certified in substantial compliance with the International Cyanide Management Code (Cyanide Code).

The Gosowong Mine and the PT NHM Gosowong Mine Supply Chain were initially certified in full compliance with the Cyanide Code in September 2011 and recertified in full compliance in 2016.  As required under the Cyanide Code, Newcrest’s Gosowong Mine and PT NHM’s Gosowong Supply Chain were again audited against ICMI’s Mine Verification Protocol and Transportation Verification Protocol within three-years of their previous certifications by independent professional third-party auditors. ICMI has received and accepted the auditors’ Detailed Audit Findings Reports which found the Gosowong Mine and the Gosowong Supply Chain in substantial compliance with the Cyanide Code’s Principles, Mining Practices, and Transport Practices. The operations can be fully certified once they have implemented their Corrective Action Plans and achieved full compliance with the Cyanide Code. The Summary Audit Report, Auditor Credentials Form, and Corrective Action Plan for the operations are available on Newcrest’s Signatory Page on the Cyanide Code web site:, and on PT NHM’s Signatory Page on the Cyanide Code web site: The operation must be re-audited three years after this date 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 this 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
