RE:RE:RE:Message from CEO of Arianne PhosphateAccordin to the feasability study the magic number is $79. That said the actual price today is hard to pinpoint. The price for 30% is about $90 and Arianne's purity of 39% gets a much higher price.
The feasability study was done before all the impovements so it is safe to say the $79 level is much lower.
Basically the mine would be profitable even in today's price range at historic lows.
