Fair point on the geology vs mining geology.

Ok if you can't wrap your head around ranges, inferences and estimations here is a simpler breakdown.
The absolute value of mining was $5.19/t. The absolute value of processing was $19.3/t. The absolute cost to break even on mining and processing the tailings combined is $15.82 at a recovery of 75%. As you so kindly pointed out its actually 50% recovery which would be about $10.54.
