7.5 million pounds windimurra uranium, page-4

Can anyone here that knows about Uranium production please verify these figures.

The grade reported is similar to the Ranger Mine operated by ERA. Source: http://en.wikipedia.org/wiki/List_of_uranium_mines
(Windimurra is 0.17%, Ranger is 0.2%)

Production costs for Uranium are around US$20/kg, so that works out to be around US$44/pound.

Current Uranium price is US$93/pound.

Therefore profit of 7.5 million pounds of Uranium (if sold today): $367 million

Are my back-of-the-envelope figures wrong?

Cheers,
Richard.
