Naica Mine, Mexico The Naica Mine of the Mexican state of Chihuahua, is a lead, zinc and silver mine that also contains extremely large gypsum crystals. Located in Naica in the municipality of Saucillo, the Naica Mine is owned by Industrias Peñoles, the world's largest silver producer. Caverns discovered during mining operations contain gigantic crystals of CaSO 4 · 2 H 2O (calcium sulfate dihydrate, gypsum, also sometimes called selenite when well crystallized) as large as 1.2 m (4 ft) in diameter and 15 m (50 ft) long. Peñoles announced in October 2015 that it was indefinitely suspending operations due to uncontrollable flooding at the Naica Mine... #info #EverythingsInfo
