          The International Mining Convention is the largest mining event in our country, and one of the largest worldwide, since its first edition in 1955; it has been characterized as a forum for innovation and linkage for all members of the Mexican Mining Sector.

          Mining Companies, Service Providers, Government Authorities, as well as the Academy meet every two years at the International Mining Convention, with the firm intention of exhibiting the advances that our sector has had, as well as establishing commercial relations and agreements aimed to the growth of the Mining Industry in Mexico.
