Situated in the midst of one of Europe's best examples of limestone karst scenery, this tiny, Victorian lead mine hosts the most remarkable deposit of smithsonite in the British Isles. The sphalerite vein has been completely altered to green, yellow, grey and white botryoidal smithsonite!
This is an extremely large example of yellow and green coloured botryoidal smithsonite lining cavities cavities associated with small pockets of deep purple fluorite.
The colour of the smithsonite is caused by the presence of cadmium sulphide. Sadly the mine dumps at the site were bulldozed back down the shaft several years ago meaning no new specimens will be coming from the locality.
