The rubbish dump like slope is still accessable, there are ropes lower down inside the mine. Ore hoppers are collapsing in places but like JB says if you don't really touch anything you'll be ok.
Will be doing a trip next saturday the 21st with a view to reaching the far end, now i have a full plan of the place, there are things I want to try and find. I still think there is plenty to see, but it's knowing where to look!
The management thanks you for your co operation.
