A  court in Marathon has fined a mining company $130,000 for two separate incidents that resulted in injuries to workers.

In one case, the Ministry of Labour had charged Wesdome Gold Mines after a March, 2012 accident at the mill operation for the Eagle River mine, 35 kilometers south of White River. The accident resulted in an employee suffering cyanide poisoning and chemical burns on his leg.

The ministry said the worker inadvertently stepped into a hole that wasn't visible because it was covered with dirty water. The hole also contained sodium cyanide.

Wesdome was fined $70,000 for failing to have an alarm to warn workers about the presence of cyanide gas during overflows or spills.

As well, the company received a $60,000 fine for a June, 2011 incident in the mill in which a worker suffered broken bones when he slipped on a plastic screen covered in a chemical.

Wesdome pleaded guilty to failing to ensure a safe means of access was provided where workers are required to work, operate, maintain or service equipment.

In addition to both fines, the court imposed a 25 per cent victim surcharge. The surcharge is credited to a special provincial government fund that assists victims of crime.
