thermal coal price

I'm assuming that the drop in stock price yesterday was due to the recent spot price of thermal coal and the fact that xtrata just did a deal with Japan for $70 tonne.

Not sure why we got the late bounce in the last minutes of trade.

Does anyone have any idea what the CEY shareprice was last time coal was at 70 - 72 per tonne?
I know at that time cey also didn't have the capacity that they do now also no focus on international business.
