And lastly...... The “Antonina” mine, located near Toral de los Vados (León), exploited lead, zinc, COPPER and mercury mineralization since 1935, reaching tasks of some importance until its closure in 1983. Traditionally known for its Blue aragonite, the activity of collectors' teams reveals in 2001 the existence of extraordinary alteration minerals, particularly blue hemimorphite, auricalcite and rosesite, probably the most notable known in Spain.
