Australian Vanadium adds another battery metal to the mix at Gabanintha Vanadium Project

Cobalt, nickel and copper have been recovered at saleable levels in tests on a sulphide concentrate.

Australian Vanadium Ltd (ASX:AVL) has added another saleable battery metal opportunity to its flagship Gabanintha Vanadium Project with cobalt, nickel and copper recovered in a sulphide concentrate.

Bench-scale tests on Gabanintha fresh high-grade massive magnetite have resulted in the recoveries from non-magnetic stream.

Sulphide concentrates produced from flotation contain 3.8 to 6.3% base metals, including 1.54 to 2.02% cobalt, 1.36 to 2.58% nickel and 0.82 to 1.70% copper.

A sulphide recovery circuit will now be evaluated as part of the pre-feasibility study (PFS) processing flowsheet for the project in Western Australia.

Shares are up almost 10% to 4.5 cents.

Managing director Vincent Algar said: “Since we initially identified this opportunity, we have been interested in its implications for the project.

“Adding a high-value battery focused metal to the product suite at Gabanintha could potentially prove an important revenue stream.

“This would further enable AVL’s Gabanintha project to be on the lowest end of the vanadium cost curve.”

The company previously reported significant cobalt assays from drilling in fresh rock containing vanadium in magnetite.

Cobalt pricing is at all-time highs due to its position as a strategic battery metal.

Cobalt demand is increasing

Increasing demand for cobalt, as well as demand from consumers for ethically sourced cobalt, has contributed to a price rise to over US$90,500 per tonne.

AVL is preparing a mineral resource update at Gabanintha, which will include sulphur and base metals.

This will allow these components to be included in the pit-optimisation and PFS studies, which are underway.

Further optimisation tests

Further flotation optimisation tests will be undertaken on the bulk composite reserve and future drilling is being designed to target sufficient sample mass.

This work will allow the company to optimise a sulphide recovery flowsheet, improve concentrate quality and determine an overall base metal recovery.

The company plans to engage with potential Australian and offshore buyers to discuss indicative terms for the sale of a sulphide concentrate.

All-time high cobalt prices and recovery parameters indicated by the work, add support for additional drilling to expand the vanadium resource and better define the sulphide by-product potential.

Potential to increase revenue

Sale of a by-product cobalt, nickel and copper sulphide concentrate has potential to increase revenue at Gabanintha.

Bryah Resources Ltd (ASX:BYH) holds the rights to nickel, copper and gold recovered from any Gabanintha production, however, AVL will benefit from this due to its 14% holding in Bryah.
