Some interesting history about the treatment of Wiluna refractory ores (just copy-n-paste the below link into your web browser if you're interested in some Wiluna refractory ore history)....
I don't think there's anything wrong with Wiluna, just the gold trapped in the arsenic mineralisation seems to be a stubborn commodity....or perhaps the Wiluna Sleepy Giant is just a grumpy dude who doesn't like sharing too much gold with WMC at this stage of the game.
