Vanadis IPO, page-295

The Chinese managed to recover 78.4% for the Intermin Resources joint venture (which also has shale vanadium with a similar grade in Australia). 

'Initial two-stage concentration tests resulted in a 1.1% V2O5 grade in 39% of the mass at a 78.4% recovery. 

Further testwork underway to optimise the pre-concentration stages with the aim of delivering a 1.5% - 2% V2O5 feed stock at acceptable recovery for downstream processing testwork

The Lilyvale prospect has an Inferred Mineral Resource (JORC 2012) of 670Mt grading 0.35% V2O5 at a 0.29% cut-off grade

Lilyvale is the initial development focus and forms part of the greater Richmond project with a Mineral Resource of 2,579Mt grading 0.32% V2O5 at a 0.29% cut-off grade'
