This was found as small draughting hole which was opened up to reveal a possible shaft with a "bulge" preventing entry. This was bypassed by breaking through the far wall into a small, sloping chamber with a hole at the bottom apparently leading into a shaft. The hole proved awful for capping but eventually was made large enough for ladder access onto a shaft. Some possibilities closed down but a rift with the draught was accessed with a hammer. This was pushed to a small chamber with the draught coming upwards through a narrow rift which requires caps.
While the hole was being surveyed, another shaft was opened up.

The area was investigated in October 2017. "Alf's" shaft was a free climb into a reasonable passage which ran under "Phil's" shaft, giving maybe a further 30m length, in total. The passage got to a split with the left hand branch effectively ending at an outward draughting small downward tube. The right hand branch dropped steeply to a large calcited ?plug? in the floor with a draught forcing its way up between wall and calcite. This probably deserves a visit with the usual digging paraphernalia.
