All I know is in 2014/5 MCO had about 6 or 7 MINs and decided to only maintain MStar, RoD and Wallaby and that of the various snr management team (mine managers and geologists not the Garlings) each liked a different prospect for different reasons and that Wallaby was a favourite.
I think in our earlier releases we put in some pictures and historic production numbers for Wallaby and that it was an open cut target.
