A large fluorite-quartz vein (250 m in long, 4 m in width) hosted by a migmatitic granite. This deposit was mined for fluorite from 1906 until 1977 by shafts and galleries. At the year of closure, it had been dug up to 244 m depth and 386 000 tons of ore had been produced. This mine has become very famous for its beautiful "electric-blue" fluorite crystals that developed in quartz vugs.
