PT Indotan Halmahera Bangkit Cyanide Code Participation Ends

The International Cyanide Management Institute (ICMI) announced today that PT Indotan Halmahera Bangkit’s participation as a signatory to the International Cyanide Management Code (Cyanide Code) has ended. PT Indotan Halmahera Bangkit became a mining signatory to the Cyanide Code in May 2021; its subsidiary PT Nusa Halmahera Minerals operates the Gosowong Mine in Indonesia. The mine had been certified, but the certification expired which has resulted in the company’s termination from the Cyanide Code program.

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. It 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.

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
