This pit attempted to work the difficult geology near the southern outcrop. Closed in 1904, the colliery is remembered for a Mining accident tragedy that occurred on 26 August 1892 as 146 men and boys were working within the mine.
At 8.20 am an explosion occurred apparently due to a hole in one of the workers' Davy lamps. Rescue attempts were hampered by roof falls, but by 4pm 42 miners had been brought out alive, some of who however died later of their injuries. The final death toll was 110 men and boys.
