Hi Erik. There are a good number of metal mines in Scotland but many have been filled in by land owners with only surface remains. One mine open to the public is in the village of Wanlockhead in Dumfries and Galloway. There is a list on this site of some of the mines, Use 'Information And Resources', click on 'General Interest', then scroll down a some way to 'A Gazetteer to the Metal Mines of Scotland' it is dated 2/9/14. Hope this helps and you have a great trip. JL
