First worked in the early 19th century for lead by the Beaumont Company, Blackdene Mine near Ireshopeburn is now mostly collapsed and inaccessible.  Here we have an adit, collapsed only a few yards in leading to a line of stopes, the depressions of which can be seen on the hill above.  However there is an open stope which may be worth an extra look but a rope and access gear will be required.
