I was just reading the following article, which I dare say may be of interest to people...

"Part of a disused mine gave way at Glebe Mine on Friday morning, causing water to burst from a lagoon into nearby shafts and streams" - I'm guessing with the site being in operation that there is nothing accessible to the caver?

It would sound like there is still the potential of future damage to caves in Stoney.
