Ann: Alliance South Mine Update, page-58

Sure, will do
From my interpretation on the ann the external analysis seemed to only cover the reconcilliation. I couldn't see explicitly where any analysis was done around the sampling from the channel faces themselves
Basically it seems they used a 3kg sample to extrapolate out to around 37,000kg of reef material (for a 1.7M wide reef channel face) and some 87,000kg of drive material (4x3M)
I might drop management and email to confirm if my assumptions are correct or not.
