I am walking as I type so I can't give you exact numbers but if you actually work the inventory change its closer to 350k tonnes . Debt has changed by 9m
I think showing you 44 m of the 50m you claim GRR generated from operations didn't occur and I am not even including the 10m mill upgrade deferral I would call that very material,and it renders your claim that GRR made 50 m last year manifestly incorrect
As for the NTA claim , I have seen many a 200-300m mine NTA vanish into thin air . The asset is worth only what profit it can generate . For commodity companies it's the one line item I place the least value on as it can be halved or eliminated with the stroke of a pen
