“It’s definitely the very best consequence by way of the area the place it was discovered. There’s been a lot dialogue working by means of the doable consequence that we wouldn’t discover it and given the truth that it may’ve been wherever from the mine to the metro web site, this might presumably be the most effective space. And to do it in such a brief time frame is just superb.
“There was all the time a way that we have been going to search out it it was simply precisely how lengthy and the worst doable consequence was that we’d nonetheless be right here in 12 months’ time.”
What has Rio Tinto stated?
