No - 20t of 0.4% ore turned into a 2% con is approximately 25% recoveries and 5% mass yield.

I don't know what the process for that was, I was just working off the figures in the announcement.

Conversely AVL have something like 60-70% recoveries and 70% mass yield or something like that (can't remember off top of my head). They are basically taking just under 100t of 1% ore per tonne of 98% flake.

PUR in comparison assuming 90% recoveries from a 2% con in stage 2 would take 20 x 98%/(2% x 80%) = 1,088 tonnes. It's hugely different.

I have no quals in any of this though and could be missing something but my numbers seem to align to figures in the announcement where they say 80Mt of ore boils down to 80,000t of contained V2O5
