ASX-listed vanadium developer Venus Metals has delivered a 22% increase in tonnage for its flagship Youanmi vanadium oxide project near Sandstone in WA, after a very successful resource definition drilling program over the deposit last year.
Importantly, 64% of the mineral resources now sit in the high-confidence measured and indicated categories of classification, with the new global JORC-compliant estimate ringing the till at 134.7 million tonnes grading 0.34% vanadium pentoxide.
The company can now confidently move ahead with scoping studies and hydro-metallurgical test work programs, with expectations of defining a maiden ore reserve for Youanmi down the track, based on more targeted drilling and technical studies.
Venus Managing Director Matthew Hogan said: “As the world transitions into a low-carbon future it will require significantly more power storage capacity.”
“Vanadium is a sustainable metal allowing unlimited storage life and capacity for clean energy as well as stronger, lighter and more resilient steels and alloys for infrastructure and transport.”
“Vanadium is currently at the forefront of technology innovation yet it is in short supply. With our now proven world-scale resource base at Youanmi, we believe we have the potential to unlock the project with new processing technology advancements in vanadium extraction from oxide ore”.
For reference, the current price for high-grade vanadium flake in China is trading just under AUD$53,000 a tonne, nearly six times the price of copper and three times the price of nickel.
And Venus’ Youanmi vanadium oxide project is better than most, with positive metallurgical leach extraction test work announced in January, showing very encouraging recoveries and upgrades
According to the company, the preliminary test work showed that the oxidised vanadium ores were amenable to beneficiation, with extractions up to 80% producing an impressive assay grade of 0.6% vanadium pentoxide.
Venus’ metallurgical contractor METS is completing further studies to optimise the appropriate processing flowsheet to underpin the scoping study for its Youanmi project.
This work will involve linking the geological and metallurgical characteristics of the oxidised ores to further tweak the ongoing test work.
The metallurgical work concentrated on the top 30 metre, higher-grade section of the Youanmi deposit and the new mineral resource largely defines the top 50-metre section of the ore body, hosted within the soft oxidised ores, which set Venus’ project apart.
As a result, the vanadium-rich oxide mineralisation at the project looks perfect for a low strip ratio, cheap, bulk open pit mining operation.
But this is just to start for the company, with drill targets defined over an additional 25km of strike at the Youanmi project, which is 90% owned by the company and located favourably near excellent regional infrastructure, including a gas pipeline and only 460km east of Geraldton Port.
So, its onwards and upwards for Venus, who has a serious shot with the Youanmi vanadium oxide project and will now accelerate its technical, environmental and engineering studies to more quickly capture the latent economic value of the venture.
