Ann: Half Yearly Report and Accounts , page-3

I'm no mining expert but we look pretty resilient if I am interpreting the figures correctly.

Our average realised price was 118.50 per tonne and there were 385,213 tonnes shipped and a maiden profit of 32.63 mill. Drop 20/t off the IO price, drop 7.7 mill off our profit and it would have been 24.9 million maiden profit.

Get extreme and drop IO price another $20 to $78.50/tonne and we'd have had 17.2 million profit. Not as pretty, but we still look pretty damn resilient if you ask me.
