Rio Tinto would never consider buying Niocorp. They like high grade. Last year they bought Platina’s high grade at surface scandium deposit that is scalable and has a long mine life for $14mm. They are also current producers of scandium and aluminium/scandium alloys. I don’t think they would take it if it was given to them. The is just a machine to extract high salaries for the ex Molycorp gang for as long as they can. Utter scam.
