Comil Cotaxé Mineração


Heleno Losumar Ferreira de Castro was born in 1934 in Aimorés/MG, a city located on the banks of the Doce River, the son of the city's traditional family. From a very early age, he had to leave the city and his parents to study at a boarding school in Rio de Janeiro, where he spent much of his childhood.

Among his greatest passions were aviation and the mangalarga marchador, both still worshiped by their relatives.

In the late 1950s, he went to work and study in the United States, more precisely in New Orleans, where he stayed for approximately five years and had the opportunity to study at one of the major American universities at the time, Tulane University. Even so, he never abandoned his roots and was always present in the life of Aimorés.

One of the main characteristics of his personality was education and elegance, without ever losing simplicity, humility, unconditional loyalty to friends and above all seriousness in dealing with people and in conducting business. He was a man who liked people and good conversation and often went to some of his employees' house where he tried to help them with good advice and always with a friendly word.

He has always honored the local community since he acquired the properties in Cotaxé, long before he founded Comil Cotaxé® in 1993.

Mr. Losumar passed away in March 2007 and is still present in how the company relates to its employees, partners, suppliers, customers and the community.
