Case Study: The First Mine Certified Under Cyanide Code

In January of 2007, Marigold became the first gold mine in the world to be certified under the International Cyanide Management Code—and continues to maintain its certification. The “Cyanide Code” is a voluntary initiative that focuses on the safe management of cyanide in gold and silver mining, and the production, transportation and use in the recovery of gold and silver). Originally developed under the guidance of the United Nations Environmental Program (UNEP) and the then-International Council on Metals and the Environment (ICME), its comprehensive requirements include financial assurance, accident prevention, emergency response, training, public reporting, stakeholder involvement and verification procedures. 46 mining companies (some representing a portfolio of compliant mines) are now signatories.
