Atlantic Gold’s manager of environment and permitting, James Millard, calls it a “spill” or a “loss of control” caused by a “gasket failure.”

By whatever name, the event happened on the night of January 3, 2019, at the company’s open pit gold mine at Moose River. It involved 380,000 litres of contaminant-laced slurry, which flowed from the processing plant where ore is crushed and gold extracted, and down a trench underneath the double-lined 500-metre pipe that should have been carrying the effluent to the tailings pond.
