The website when I was reading made much of the tailing dam exceeding original design specifications but according to Wikipedia the original design specifications grossly underestimated the rainfall in the region. Nice to exceed original specs but not actually nice enoug. The original authorization of the mine required water to be contained at all times.
The Mirrarr people and the Gundjeihmi Aboriginal corporation are opposing expansion of the mine, asking how a mine that can't meet current standards can be allowed to expand. The Greens are asking the same question.
The mining companies sort a foot in the door so they could shove it wide open.
So is ERA practicing green wash of the darkest hue?
