Ann: Bankable Feasibility Study Update, page-17

You can have a look at old production reports form NAV for further information. I'm looking at one from September 2012 which shows recovery of 91.7% from 1.5 g/t milled grade. 'Direct cash cost' was A$1170/oz. So probably AISC more like A$1300/oz if I had to guess.

The December 2012 production report did list a few mechanical issues with the plant. Grade then tailed off in January/February 2013 due to rain making higher grades unavailable, shortly before administrators were appointed.
