Newcrest Mining Ltd.’s Lihir Island Mine and Lihir Papua New Guinea Cyanide Supply Chain Recertified Under the International Cyanide Management Code

The International Cyanide Management Institute (ICMI) announced today that Newcrest Mining Ltd.’s Lihir Island Mine and the Lihir Papua New Guinea Supply Chain, both located in Papua New Guinea, have been recertified in full compliance under the International Cyanide Management Code (Cyanide Code). This is the second certification under the Cyanide Code for the Lihir Island Mine, and the third certification for the Lihir Papua New Guinea Supply Chain.

Newcrest is a signatory to the Cyanide Code as a gold mining company and Lihir Gold Limited is a signatory as a cyanide transporter. The Lihir Island Mine was initially certified under the Cyanide Code in November 2019. The Lihir Papua New Guinea Supply Chain was initially certified in August 2013 and was recertified in April 2017. The mine and the supply chain were again audited against ICMI’s Mining Operation Verification Protocol and ICMI’s Transportation Verification Protocol by independent professional third-party auditors, and ICMI has received and accepted the auditors’ Detailed Audit Findings Report and Summary Audit Report for the Lihir Island Mine and for the Lihir Papua New Guinea Supply Chain, which found that the operations had maintained full compliance with the Cyanide Code’s Principles and Standards of Practice since their previous certifications.

The Summary Audit Report and Auditor Credentials Form for the Lihir Island Mine are available on Newcrest’s Signatory Page on the Cyanide Code website. The Summary Audit Report and Auditor Credentials Form for the Lihir Papua New Guinea Supply Chain are available on Lihir Gold Limited’s Transport Signatory Page on the Cyanide Code website. The operations 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.
