A year after a miner was killed by cyanide poisoning at Detour Gold’s Cochrane mine, the company has been charged.
The investigation is in its final stages and the company has received more charges as a result.
In total, the company is facing 14 violations of the Occupational Health and Safety Act.
Three supervisors were also charged by the Ministry of Labour.
A valve containing sodium cyanide broke and the solution was inhaled by 52-year-old Denis Millette, killing him.
The reason mining companies use cyanide in such a way is to separate gold particles from ore.
