have you really looked at the quarterly financial report, it takes 170 per ton at the current level of production be get into the green, they are losing money at $150 per ton, I did an analysis on this earlier and showed you how to figure this, you have to put in all costs not just those of mining as the company spouts. You will see shortly that they lost money at $150 as this quarter is nearing an end, for that matter they averaged 150 per ton last quarter and lost 570M not including the write down. You really need to do more DD before you make such statements so you can look a little more intelligently about this.
you are wrong. Their Max cost per tonne is $75 . if it was $170 they would never had made ton of money in 2011 and early 2012. Go listen to their conference call on 2/12 and it says all about their cost at different mines.
