The International Cyanide Management Institute (ICMI) announced today that Harmony Gold Mining Company’s Target Plant, located in South Africa, has been certified in full compliance with the International Cyanide Management Code (Cyanide Code).

The Target Plant was audited against ICMI’s Mining Operations Verification Protocol by independent professional third-party auditors and was found in substantial compliance in July 2024. The Summary Audit Report and an associated Corrective Action Plan were posted on the Cyanide Code website. ICMI has received and accepted a Corrective Action Plan Completion Report from an independent professional third-party auditor verifying that the Corrective Action Plan has been fully implemented and that the Harmony Plant is in full compliance with the Cyanide Code. The auditor’s Corrective Action Plan Completion Report is available on Harmony Gold Mining Company’s Signatory Page on the Cyanide Code website and the Corrective Action Plan has been removed.

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. We invite you to read our 2024 Annual Report, which can be viewed here.
