A large stratiform deposit of baryte hosted in Bajocian limestones mined for lead (20,000 tons) and zinc (45,000 tons) until 1963. The ore is found between layers of limestone or in cracks. It was the main mine in the department during the 20th century. Today, large dumps are still visible but adits are closed.
