The definitive feasibility study is on track for delivery in the June quarter of 2019.
The met work results are an improvement on the previous high-purity results
Technology Metals Australia Ltd (ASX:TMT) has received results from more metallurgical test work on samples from the Gabanintha Vanadium Project in Western Australia.
Refinement work on a sub-sample delivered a vanadium pentoxide (V2O5) product with a purity in excess of 99.7%.
The V2O5 product came from an ammonium metavanadate precipitate that recovered over 98% of vanadium from a leach solution.
This high purity further confirms the suitability of Gabanintha vanadium product for the speciality chemical, battery and aeronautical industries.

Preliminary base metal recovery test work delivered highly encouraging flotation concentrates with a combined base metal content of 10% to 15%, containing up to 2.31% cobalt, 4.47% nickel and 9.50% copper.
This test work focused on the non-magnetic (tailings) fraction from the magnetic separation process.
Notably, significant scope exists to optimise the base metal recovery into a concentrate product.
TMT’s managing director Ian Prentice said: “Improvement on the already high purity V2O5 product following a simple refinement step underscores the very high quality of the World class Gabanintha deposit; whilst the ability to produce a high grade base metal concentrate from a the non-magnetic tailings stream has potential to be a significant bonus for the project.”
