ON MEXICO ISSUES

  • Fitch Ratings stressed that the new mining law is to have far-reach implications in the Mexican mining industry, as it is to slow the pace of exploration, shorten the concessions term and generate worries on the operational continuity, and also to revitalize community negotiations. Even as the details are still to be defined, exploration is the activity that will be hit the hardest, with exploration activities now to be conducted by the Servicio Geológico Mexicano (SGM) and later expanded by special collaboration agreements.

ON EXPLORATION
