Remains of nineteenth century mine shafts and adits at Eylesbarrow Tin Mine, which was mined from 1814 until 1856. An English Heritage archaeological field survey identified 25 shaftheads of which 16 have names recorded in documentary sources.
Most of the shaftheads comprise conical pits between 9 metres and 16 metres in diameter, surrounded on the downslope side by either a crescentic or linear spoil dump up to 3 metres high. Some also have remains of masonry collars. It is likely that the majority of the shafts would originally have had collars, particularly those associated with winding or pumping equipment but they were destroyed or obscured when the shafts were capped after abandonment. At least five of the shafts were associated with pumping equipment, powered by the two waterwheels located on the lower flanks of the hill. Three shafts Pryce Deacon's Shaft, Henry's Engine and New Engine all have evidence of balance bob pits built into the upper rim of the shafthead. Six of the shafts were used for winding.
