Just a little confused on your posts so if you wouldn't mind clarifying for me since you are highly experienced in this field.
You say from the pics you don't see any obvious signs of niobium but see several minerals found in the same environments.
My questions is isn't the historical gulf studies which I think you state were done exceedingly well give you enough data to say there IS a huge niobium deposit there?
I am just a bit confused on your point of view of what we have here.
