Hidden Valley Gold Mine Fully Certified Under International Cyanide Management Code

The International Cyanide Management Institute (ICMI) announced today that the Hidden Valley Gold Mine, a joint venture of Newcrest Mining Ltd. and Harmony Gold Mining Company located in Papua New Guinea, has been certified in full compliance with the International Cyanide Management Code (Cyanide Code).

The Hidden Valley Gold Mine was found in substantial compliance with the Cyanide Code during its initial audit. The mine was conditionally certified in April 2014, and its Corrective Action Plan was posted on the Cyanide Code web site. ICMI has received and accepted a report from an independent professional third-party auditor verifying that the Corrective Action Plan has been fully implemented and that the Hidden Valley Gold Mine is in full compliance with the Cyanide Code. The auditor’s Corrective Action Plan Completion Report is available on the Newcrest and Harmony Signatory Companies Pages of the ICMI web site: http://www.cyanidecode.org/signatory-company/newcrest-mining and http://www.cyanidecode.org/signatory-company/harmony-gold-mining-company, and the Corrective Action Plan has been removed.

The Cyanide Code is a voluntary industry program for companies involved in the production of gold 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 www.cyanidecode.org.
