In reply to Lankyman:
> There are tin mines but I suspect they would be one way to a quick death for the unwary and un-knowing, rather like the copper mines found above Coniston.
Mines are wonderfully interesting to explore but also INCREDIBLY dangerous.
eg: 100yr old (rotten) roof supports and apparently solid floors which are basically just a pile of consolidated rubble.
> Caving equipment and climbing equipment are not the same thing ........... and the gear needed for this is not what climbers would normally have to hand (a dedicated SRT rig).
Just getting interested in caving and would agree that almost none of my climbing kit is suitable for caving use.
