Eylesbarrow Stamping Mill Number 2. Extensive dressing floor. Stamps on one side of wheel only. Before reaching the wheel, the water was carried for some distance on an artificial embankment to ensure a sufficient fall onto the wheel. The embankment terminates several feet short of the wheelpit, space between presumably occupied by a wooden launder. A wall divides the wheel pit from the stamping area; this seems to have screened the stamping machinery and mill operators from water cascading beside the wheel. Four large settling pits in the lower part of the floor are roughly rectangular.

Site visited on 9th May 2002. Stamping mill 930 metres south west of Eylesbarrow, forming part of Eylesbarrow Tin Mine. The wheelpit wall on the eastern side is 2.3 metres high and appears mortared, although this may be the result of later consolidation. The 1.2 metre wide wheelpit is filled with rubble. The opening through the wall to carry the axle is 0.7 metres high, originally 0.6 metres wide and 0.55 metres deep. Evidence of recent consolidation. Covered with grass and nettles.

When work commenced at 'Ailsboro Mines in 1814 a programme of refurbishment was undertaken and three stamping mills were referred to as 'New Mill'. These included Stamping Mill Number 2 which was thatched and a new leat was under construction. All the stamping mills at Eylesbarrow Tin Mine consist of a level stance cut into the slope with a revetted retaining wall on the upslope side and return wall on one or both ends. The rectangular open ended wheelpits are sited at right angles to the revetment. Upslope of the wheelpits are raised leat embankment which would have supported wooden launders. A stamping area can be identified at each mill immediately adjacent to the wheel which consists of a stone revetted level platform raised above the dressing floor onto which the Cornish Type stamps would fall onto the ore contained within a timber coffer. The upper surfaces have robust granite kerbs. The mills would have used the wet stamping process washing the crushed particles through a perforated grate into a stone-lined settling pit sited on the dressing floor. Below the main dressing floors are a range of secondary 'buddles' and tailings pits which would have further refined the tin concentrate. The water-borne concentrate and waste would be transported between processes via a system of wooden launders, channels and underground conduits.

A waterpowered stamping mill with attached dressing floor at Eylesbarrow Tin Mine. The stamping mill was built in 1814 and is one of six aligned along the Drizzlecombe Valley and was included in an English Heritage archaeological field survey of the tin mine in 1999. The mill consists of a level stance of ground with a revetted retaining wall on the upslope, eastern side with a return wall on the south end. The rectangular, stone wheelpit is sited at right angles to the revetment , measures 8.2 metre by 0.9 metres. Upslope of the wheelpit was a wooden launder channel which took water at correct height to overshot wheel. A deep open tail race channel diverted water away from the wheelpit. A stamping area situated to the south of the wheel comprises a 2.6 metres by 2.2 metres stone revetted platform, raised above the dressing floor onto which the Cornish set of stamps operated. The mill used the wet stamping process; a flow of water was passed over the base of the stamps, washing the crushed particles through a perforated grate, into a stone lined settling pit sited on the dressing floor. The settling pit measures 2.8 metres by 0.9 metres long and has a lining of flat granite slabs. Three secondary buddles and tailing pits are situated below the main dressing floor. These measure approximately 8 metres by 3 metres and survive a depth of 0.5 metres. A possible 'reck house' has been built into the south wall of the dressing floor.
