Alexandre Sion is a professional I have had the pleasure and privilege of working with. First, together at Vale and then as a direct report at MMX and Anglo American. Leadership and the ability to manage people and strategic projects are natural abilities. He is an excellent professional and a person of integrity in his values and convictions, with intense experience in the law.

Alexandre is an outstanding student. During the time we studied together in Davis, California, I could realize that he is very disciplined, organized and is always looking for opportunities to learn and share knowledged with his colleagues. I should also mention his extra class behavior – he was perceived as a leader, organizing activities and always being available to help and cooperate with his classmates.

Alexandre is a first-rate professional. I had the great opportunity to work with him at Vale, me in the maintenance department and him in the legal department. Whenever I turned to him, he was always able to give me answers in a short space of time, with a great deal of background information, so that we were always on the right side of the situation. He is ethical, proactive and keeps up to date.
