Our Mining Expertise

Collect with conscience

Terresis is a precious resource of which we are the guardians. Every extraction of this exceptional mineral is the result of a commitment to our planet and its people: we act responsibly to ensure the balance necessary for a sustainable future.

From our integrated mines...

We don’t just extract magnesia: we reinvent its place in the modern world, turning every challenge into an opportunity for innovation. With responsibility, our teams collect magnesium carbonate from our three strategic sites: Eugui (two mines) and Borobia in Spain, Jucás in Brazil .

... At our processing plants

The ore is then transported to our mills located a few kilometres from the deposits. From Zubiri in Spain to Jucás in Brazil, magnesium carbonate is washed, sieved, sorted and then calcined. Our mission: to offer the industries of tomorrow solutions that are both efficient and sustainable.

A future that is written together

We contribute to industrial development and quality of life in the valleys where our mines and factories are located. Every day, we seek to reduce our environmental impact through innovative technical processes and best practices. Once mining is complete, we are committed to full site restoration and reintegration into their natural environment. Our goal: to pass on the best legacy to future generations.
