Not sure about the grades in %
NIP 851MT @ 0.32% = 2.72MT
AXO 502 MT @ 0.65% = 3.26MT
IRC 4.9BT @0.37% = 18.13MT
Niplats' resource is near or on the surface which may be an advantage, not sure about the logistics of AXO. IRC has moly with the vanadium which may present a challenge for extraction.
Looking forward to the PGE's
