The whole bit about 3 concessions max reads as if it applies to an individual and his family and not to a corporation. This would make sense as Ecuador doesnt want these individuals who are not serious and/or who have accumulated large numbers of concessions with their relatives name's on it. Does this apply to only single people?

Article 4
The extinction is declared with no economic compensation for those mining concessions that in number greater than three have been granted to a single person or their spouse, or to judicial persons and their related companies, be it via the direct participation of the judicial person, or its shareholders and their family members up to the fourth grade of blood and second of affinity.
