The adit north of Welsh shaft under the village of Agneash was lost since the closure of the mines but in 1989 the mines group finally cleared 125 tons of rock to gain access.
The passage was found very much as it would have been in the mining years with many artifacts still lying around.
The fine stull's overhead carry the weight of tons of waste rock that the 'old man' didn't always take out. Their prime function in most cases is to give support to the hanging wall on the left.
The rail in the center was an unusual 19 inch gauge for the two steam trains, the 'Bee' and the 'Ant'.
The open adit now serves as ventilation from Dumbell's shaft.
