You'd better spend some time looking at the history of iron ore and IO pellets before making such foolish statements. Grange was the only iron ore producer that NEVER received US$50 /tonne when the iron ore crashed in Sept 2018. At the time when FMG and BHP were receiving US$50/tonne and less in 2018 , Grange was the ONLY iron ore miner getting a pellet premium of US$73/tonne. Also you need to remember that Grange gets the 65% price above other miners so when the iron ore price was US$47/tonne, Grange was actually getting paid US$170/tonne.
I suggest you need to study a bit of history of iron ore if you plan to be a smart investor, otherwise you'd better sell next week and buy Telstra or Westpac bank shares.
