Ann: Change of Director's Interest Notice, page-124

I was reading that couple of weeks ago and the way I understand is they will need to change the design on some of the walls. My thought was AISC may go up due to that but still be profitable mine with healthy margin.
But I could not workout exact numbers.

This is why I asked Nic to confirm there are no issues with the expansion. If the AISC changes by decent % then this is price sensitive and if ALK is not disclosing it then ASIC will have a case and shareholders can for class action. Especially when the Chairman has been selling during the same period.
