The code has been around for a while and was recently updated in 2012 as you mention. All ASX-listed mining companies must adhere to this code when releasing information via the ASX.

The code just ensures a high level of transparency and professional conduct in the way the resource/reserve is calculated. Companies use a vast array of information to calculate the numbers and update them when they have new information that justifies a change (drilling results, metallurgy testing, changing POG, mine planning, etc). so a bit confused by the "...all update resources and reserves at the same time" comment?

AQQ has such new information after the latest drilling and test work for the PFS AQQ hasn't updated its estimates since the last unfinished PFS in 2013.
