A jury looking into the death of two miners at Lockerby Mine is in its fourth day.

The inquest into the 2014 deaths of miners Norm Bisaillon and Marc Methé began Monday with 11 witnesses expected to testify at the five-day inquest.

The two were killed May 6th, 2014, following a controlled explosion.

The official cause of death was traumatic asphyxia from a fall of material at the 6,500-level of the mine.

The mine was owned by First Nickel Incorporated while the two men were contract workers with Taurus Drilling Services.

First Nickel was found guilty on six charges under the Occupational Health and Safety Act in February 2018, and fined $1.3 million, the highest fine ever levied against a mining company in Ontario.

Taurus Drilling, which also faced charges in the incident, was found not guilty.

The jury is expected to make its recommendations this Friday.
