Some smarty would be able work out a rough MRE with a decent cut off grade giving a conservitave reserve. Then the trouble is to work out what process would be used, the cost to build and the running costs per kg. Also possible offtake agreements.

once we figure that out we can start to get a true MC.

ive seen numbers around the internet about $10-20 cost price to produce 1kg, but they have low grades compared to us.

Theres a Niobium PFS done for company in Africa which worked out the Plant would cost around 200mil. Again i am not well educated, but different metalurgical make up could throw some of these numbers off.

Information on Niobium is scarce compared to other resources.

this is my shot in the dark without any information to back it up. All in $ USD
Cut off grade 2%: cost per kg $7
Plant construction: 250mil for a 150tph hour plant (which equates to produces 3 tph Niobium 72 tonnes per day)
Sale price of niobium (being conservative and undercutting the market) $37 per kg.
72 tonnes at (minus operating costs $30000 per ton) equates to 2.16mil USD per day, 788mil per annum)

Again this is only my thoughts. It could be 100s of mils off.
It would be enough to crash the niobium market but we would have the lowest operating cost and with a lower niobium price it might open doors for new applications.

id like to hear from anyone that has their own opinions
on cost price
plant construction price
MRE,
