International cyanide management Code
Pre-certification, Certification,
and Support Services
Johnejack CN Code Services guides clients in the gold and silver mining industry through the requirements of the International Cyanide Management Code and the certification process.
After a long career as a engineer to the international mining industry with a major consulting company, I decided to establish my own firm in 2022 to focus on offering Cyanide Code services. I began Cyanide Code auditing in 2009 for mining operations and expanded to transportation and production operations in 2017. Unlike many of the competitors in the field, I have chosen to specialize on Cyanide Code services rather than offer an overly broad range of services.
I am one of about 10 auditors in the world pre-certified by the International Cyanide Management Institute (ICMI) in all categories: lead, mining, transportation, and production. Of those, only several are bilingual (English-Spanish).
