I will read that link when I have time. Thanks for providing it.
The thing about supply is its pretty much a single source, all of the others are trying to expand their production while CBMM already has.
Niobium use is small but growing. If CBMM has enough for 100 years and can get it out and process it fast enough if growth double and they need to double production you are down to 50 years double again 25 years etc. As that mine life shortens would you as an owner and end user try and keep supply for ones future or would you limit the supply to insider end users?
With the potential growth in steel use as well as the ever growing electronic uses demand is growing and will continue it seems.
