"Who cops the risk if a tailings dam fails and mercury or other heavy metals spew into the tributaries of the Nymboida River?"

North Coast Voices post on 5 July 2011:

…………wealth is about more than money.
Quality of life and the environment feature pretty high on my agenda. And we need to be mindful of what happens after we sell off the farm. In the case of the proposed antimony and gold mines in the Wild Cattle Creek and Tyringham areas - the mining company would be Chinese, the approving authority the Bellingen Shire Council and most of the workers (and there is unlikely to be too many of them) would probably be based in Coffs.
But who cops the risk if a tailings dam fails and mercury or other heavy metals spew into the tributaries of the Nymboida River?
The Clarence Valley, of course.
And it appears unlikely to receive any of the benefits.
Mining has helped Australia ride out an international financial storm, but we need to be careful that we look at more than dollar signs when considering projects. There's more to lose than a few dollars.
