(Reuters) – An environmental group said on Tuesday it filed a lawsuit against De Beers Canada, accusing the diamond producer of failing to report toxic levels of mercury and methylmercury at its Victor diamond mine in northern Ontario.
The Wildlands League alleged that De Beers Canada failed to report mercury levels from five of nine surface water monitoring stations for the creeks next to its open pit mine between 2009 and 2016.
This was an offense under the Ontario Water Resources Act, the group said in a statement. It said it had alerted the province of Ontario and De Beers Canada to the failures more than 18 months ago.
