One thing I remember in the information sent out on underground mining on Cockatoo, in reference to the extraction of the underground ore. There was an issue stated regarding the width margin on the underground mining. I think I recall that 15mts is the minimum, and 10mts was the estimate for Cockatoo. Are there other alternatives? Don't quote me on the mts.

I know we are concentrating on developing stage 4, but I am sure there is forward thinking in relation to the underground reserves
