First worked in the late 17th century for silver ore, then during the 18th century for copper. In the 19th century it produced lead, zinc and cadmium, until it was closed in 1979. Reworked on a small scale in the 1980s for its banded rhodochrosite as lapidary material.
Famous for its beautiful banded mammillary rhodochrosite specimens.
(Buserite found at lower 7 level of the mine).
