Tando Resources has reported high vanadium pentoxide (V2O5) concentrate grades above 2 per cent “over thick zones, with high mass recovery” from its SPD project in South Africa.

The results were achieved via Davis Tube testing, which separates magnetic material from non-magnetic material.

Mass recovery, meanwhile, refers to the weight of recovered magnetic material as a percentage of the total sample.

The higher the mass recovery, the better — it means less material processed to achieve a production target (which saves on production costs), and less waste for disposal or storage.

When it comes to battery metals like vanadium it is not just as simple as looking at the grade of the ore.

The keys to determining a good vanadium deposit come down to the overall magnetite recovery and the grade of the vanadium you get from that magnetic concentrate.

Tando’s (ASX:TNO) share price was up almost 14 per cent to 10c on the news.

The latest assays returned results including 24 metres at 2.16 per cent V2O5 from surface — including two metres at 2.20 per cent V2O5 (with a mass recovery 74 per cent).

Tando managing director Bill Oliver said the Davis Tube results confirmed SPD’s potential to generate a high-grade vanadium via simple magnetic separation.

“Work is already underway on the various studies which will feed into the company’s scoping study, including metallurgical test work and pit optimisation studies,” he said.

The company says it is fully funded for the forthcoming resource, metallurgical and mining studies.
