LT, I do not understand why:

" Consider, Noront’s “Eagle Nest” with In-Situ Value of Metals nearing us$10B at present day metal prices. Did you know, that in 1996 the In-Situ Value of Voisey’s Bay was also us$10B and that Inco paid $4.3B or 43% of the Metals In-Situ Value at that time.'

Using same anology, with Eagle's Nest being in-situ 10 billion $s, why you would use a billion instead of 4B$ as a Lets See just for the Nest.
