Visited by Morrisey, R1, Boboil, Manx, Carabeener and Detritus.
I can't give too much away about this place or it's location, I don't want these superb coal tubs getting wrecked. But I don't think it's been visited or reported before.
We've called it "Sting In The Tail" Mine because it was protected by a wasp's nest and got most of our party at least once!
The place is quite extensive, so a return visit is on the cards.
