Mongolia's Mega Mine

Available for over a year

The gigantic Oyu Tolgoi copper mine will certainly make some people rich, but how many of them will be Mongolian? Ed Butler speaks to the BBC's Roger Hearing, who is at the mine, fresh from taking a taxi ride hundreds of metres below ground. He has been delving into who will profit more from this vast project in the middle of the Gobi Desert - the Mongolian state or mine operator Rio Tinto. Meanwhile, above ground, the BBC's Joshua Thorpe speaks to some disgruntled herdsmen. (Picture: Mongolian herdsman; Credit: BBC)
