basssque, IAMGOLD's (Niobec Niobium Mine) in Quebec was realizing profits of aprox. 50% on their annual production of aprox. 5,000 tonnes, around $100million per year.
NioCorp should realize at a minimum the same or more 50%+ on 7,500 tonnes projected production per annum, aprox. $160,000,000.
You will need to do your DD to get yourself properly informed. A very good start is go to NioCorp Developments Ltd.-Home, and read the last thirty news releases, that will definately get you up to speed.
GL Cheers.
