Site visited on 9th may 2000. Shaft 260 metres east-north-east of Eylesbarrow, forming part of Eylesbarrow Tin Mine. Two shafts side by side. The southern one is largest and measures up to about 5 metres deep. Grass and heather. A 2 metre wide and up to 1.2 metre wide channel leads downslope adjacent to the southern edge of the dump. This probably carried water from the shaft. Although not named this shaft may be one mentioned in 1851 and represent the final phase of activity at the mine.

Over thirty shaftheads are still visible at the 19th century Eylesbarrow Tin Mine . They consist of conical pits surrounded on the downslope side by a crescentric ring of spoil or linear spoil dumps.
Shaft 25 is in an area of earlier activity where deposits were initially exploited by either streamwork or openwork methods. This shaft is at the far north-east of the sett near the Whiteworks track. It is associated with a flaotrod system powered by Engine Wheel 1 which was not operating until 1848. It may have been the shaft recorded as being sunk in 1851.

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 have evidence of balance bob pits built into the upper rim of the shafthead. Six of the shafts were used for winding.
