To get some idea of the Canegrass value it's worth having a look at the Australian Vanadium (AVL) Gabanintha Project which is a couple of hundred Km's north of Canegrass and put out a recent presentation.

Gabanintha has a resource of 175Mt at 0.77% V₂O₅ and contained V₂O₅ of 1346Kt

Canegrass  has a  resource of 216Mt at 0.52% V₂O₅  and contained V₂O₅ 1115Kt

The Gabanintha Project has a Capex US$360m, Opex US$4.28/LB, Feed 900,000p/ producing 10,100 tonnes p/a and a Mine life of 17 years.

The project has an NPV of US$2.37 Billion based on a vanadium price of US$20/LB, the current vanadium price is around US$35/lb.
