Thanks for the link.

From the article:
"Reopening old mines because of high prices, in a market that’s small and typically volatile, is a trickier decision. “One day people will pay you any price for your vanadium, the next day you can’t give it away,” Mr. Moore said."

The vanadium price is very volatile right now. It's fallen from above $30 to under $20 this week. If reopening an old mine is a tricky decision, then opening a greenfield project is even harder.
