No I am not exaggerating. If you recall Alan said the Brack Bird chromite is currently only worth mining because the Eagle's Nest infrastructure can be used which will be paid for by Eagle's nest and the rest of the chromite is not at current prices. The value of Eagle's Nest changes daily with the metal prices but it is a small fraction of 60 billion. In fact Noront says Eagle's nest has an after-tax net present value (at an 8% =discount rate) of $543 million.
The point I am trying to make is that if you are going to be making an economic evaluation you need to be using net value numbers somewhere in your model. I am not saying that Noront is not a good investment.
