Active magnesite quarry located near the Spain - France border. The dolomite specimens found (up to 10 cm) are between the best in the world. In the quarry appear also black shales with uncommon phosphates.

Asturreta quarry is the first quarry worked in Eugui. Most of the finest dolomite specimens, and all the older specimens, are actually from Asturreta. It is located just at North of Azcárate quarry.
