Ann: Annual Report to shareholders, page-42

All that sounds great until you dig deeper and find that IOR uses rubbish 30% grade iron ore to produce 58% grade which is still garbage. IOR (exNSL) has only ever lost money and has been diluted into oblivion and then consolidated a couple of times so that they can raise more capital from suckers ( Existing shareholders).
I doubt whether IOR even gets paid the full amount owed, the company never produces Qtrly production figures, accurate sales, it never discloses costs to produce one tonne or the sales price per tonne.
All hidden from shareholders, why anybody holds is beyond me.
The share price tells it all, thankfully its your money and not mine. The roulette wheel is a better option to waste money.
There have been a lot of clowns working as management for RIO over the years, so don't think that is an endorsement.
