According to GBG:
Finance - July 2008
EPA approval for Mungada and Karara - Mid 2008
Mungada production - end of Q1 2009
Karara production - end of Q1 2010
Lodestone production is said to be at an initial rate of 10mtpa i think in 2012 or 2013.
I think 40 to 50mtpa by middle of next decade - so 2015.
Its all on the GBG website, check out their presentations.
But remember this is a blue sky estimation by them.
