Through SMS & kfw, TNG have majorly de-risked :
• The EPCM component - Detailed design through to commissioning of both the mine & refinery. This includes sourcing & delivery of long lead items as SMS manufacture much of the equipment.
SMS have done this before. They know how to deliver. They are guaranteeing the new process flow sheet will deliver so the production numbers are a known quantity.

• The Finance component kfw - finance will happen - the announcement released will have been thoroughly vetted. This is what kfw were happy for TNG to put out to the market.

Will they fast track this project?

I'd suggest they all recognize that the extremely high Vanadium prices - 10 times what they were when the DFS was released, will not be a long term thing. If they can get this plant underway by mid 2019, commissioned by 2020, the V2O5 bull market will likely still be running as Bushveld, Largo & Atlantic will be about the same time frame.
If it's mid to late 2020, I wouldn't be as confident as there are lots of Vanadium players vying to build capacity.
That one year at these high prices will pay for their plant.
