Thought this may be of ineterest.
"The rock of Clee Hill consists of up to 45m of massive and oolitic grey limestone. A number of swallets in the area have been described by Price (1971), including a cave system with a sink to resurgence distance of around 1.6 km and a fall of 45m. The main sink for the system is at FOXHOLES (SO 641803) where a stream disappears under a low cliff. Unfortunately the passage is blocked by a boulder choke and flood debris after a few yards. A shaft sunk near the entrance choke has now collapsed. The resurgence at SO 657803 is totally unenterable - the water issues from fissures in steeply dipping limestone. The stream passage was entered by an incline at SD 656804, driven by the late Duncan Glasfurd, from which it could be explored for about 45m upstream to a sump pool. The Birmingham Enterprise Club attempted to blast a way round the sump, but without success. The entrance now appears to be blocked. "

Do you mean:
TRUCK HILL CAVE, Cleobury Mortimer, Salop SO657804
The entrance leads to an easy passage 45 m in length which reaches the sump. However, at 3.6 m depth there are large boulder obstructions at a distance of 5 m from base, with a possible route around to the left. There is an associated resurgence 61 m away with a short 1.2 m length of passage. This also ends at a solid boulder choke.

I dived the sump on 11/7/1993 helped by Peter Cousins and John Stevens, here's the text of my report to the CDG NL 109:14
"Thanks to Dennis and Brenda Warburton for arranging access and for their hospitality. The entrance is an improbable hole beneath the roots of a tree in the middle of a field. This leads to a streamway ending upstream at a pool. This was dived using a single set and base fed line for 5m in a roomy passage to a large boulder. Looking over the top it was possible to see into ongoing passage and, on the second attempt, the diver was able to squeeze around the lefthand side of the block into a apparent enlargement. In the by now zero vis, the way ahead appeared to be choked. The diver's exhaust bubbles were not seen at base suggesting that they filter up through the choke. On the surface this appears to be beneath a water-logged depression."
Sounds like the same place though the NGR's are different.
