Quote on previous announcement : "Highlights  High grade Vanadium Pentoxide produced assaying 99.47% V2O5 by the AMV process route. King River Copper Limited (ASX: KRC) is pleased to provide this update on hydrometallurgical testwork completed by TSW Analytical Pty Ltd (“TSW Analytical”). This work is part of a Vanadium Concept Study into the production of high purity Vanadium Pentoxide (99.5-99.9% V2O5), Titanium Dioxide (>99% TiO2), iron oxide and Vanadium Electrolyte products (used in vanadium flow batteries) for input into a Scoping Study".

By inference, the bet is that KRC has achieved more than 99.5% purity. This will be a significant news for the company, its shareholders and the industry.
