Several parallel lodes to the valley slope gashed by ancient workings, with scree like spoil extending almost down to the river. Shallow, Intermediate and Deep Adits.
Length of Deep Adit, excluding drivages on the lode was 380 fm (700m) 4 lodes: 1, 2, 3 and 4, the later two on the plateau, the former on the valley slope, the adits intersected each. They were also intersected by three shafts: Old, New and Eastern.
The shafts were pumped via long (1/2 mile) runs of flatrods driven by a wheel below Deep Adit.
