I have a mate who is well positioned within Rio. Big plans underway to start closing some mines and making staff redundant. It won't be formal for a few months yet. They have already announced that Blair Athol is to close by years end. Perhaps JetGo won't need a second aircraft?
With China officially slowing down the inevitable writing is on the wall for some parts of the mining industry.
Not only Rio, i know that Xstrata, Anglo American and Peabody have been pre-warning contractors that there is a high possibility they will not be renewing contracts because they are downsizing their mine sites.
