Yellowknifer note that in my post I only considered the vanadium but there is iron and titanium.
They both add to the totality and therefore it may be economical even today. Iron I think needs to be only double in concentration to stand on it's own. The titanium dioxide usually used in paints also should contribute a few dollars per ton.
I am not a miner, no knowledge of how the efficiencies of operating this type of multi metal mine would pan out.
I am basicly a gold bug so I reference my comments from that environment.
All I can say with certainty is that this resource will be mined some day if enough of it can be defined.
But I am still neutral about this one for now.
Just as the company side-lined the gold so I side-line this one.
Nickel is where it's at. Cheers.
