Mina Ampliación a Victoria, Navajún, La Rioja, España
This mine-quarry is exploited to obtain pyrite only for collection and decoration. It is located 2.4 km to the NNW of Navajún, and you can access it via a track that begins in Navajún (near Cervera del Río Alhama).
From this mine the best cubic crystals of pyrite of the world are extracted. The biggest crystal so far had a size of 19 cm and weighed 9.5 kg.
