dundas - $1million expenditure by end of sep12

Hi All,
Just looking on the THR website and it says they needed to spend A$1 million on Dundas by end of September 12. At 31 Dec 11 they had already spent A$0.55 million.
Just wondering if anyone knows if this is still the case, and how this is progressing.
I can't seem to find anything in their announcements.
Thanks.
