I have it on the grapevine a new discovery in the limestone open cast mine, in the face a large opening with a big pitch to a massive chamber  i don't  if you can get permission  but it could be big ,a work mate as seen it but the manager will not let anyone go down on safety regulations  its an opening in the face a rock roles down about 10 meters and a 4 second drop and a big splash ,just a heads up for you guys ,and no this is not an April fools day wind up, good hunting .   

Then perhaps you should wait and let some one with decent understandable info post a decent report

Or see if it's still there on April the second.  :

Bit of a coincidence that April 1st and a feature in Descent coincide at Cannington!

Yea. Yea Yea. I remember the first Cannington Cavern . There wont be another one. In any case I have a friend who works there.
