Thanks guys, missed the other listings.

They say that, the mine will be left open, after extracting the 'slate' so that the bats will have a home!
It would not be the first time that these little critters have helped to prevent a mine's closure, so guys if you find any sleeping, just leave them alone, and also remember they feed prolifically on midges!
