MEXICO CITY (Reuters) — Mexican President Andres Manuel Lopez Obrador's proposal to ban open-pit mining will generate uncertainty and curtail investment for the key sector, mining industry representatives said this week.
Lopez Obrador announced the proposal to prohibit new concessions for open-pit projects last week amid a slew of initiatives as he looks to shape political debate ahead of a June presidential election that his protégé is expected to win.
