Gabanintha Vanadium Project

Gabanintha Vanadium Project – Western Australia

The Gabanintha Vanadium Project consists of the Gabanintha high-grade V-Ti-Fe deposit located in the Murchison Province approximately 43kms south of the mining town of Meekatharra in Western Australia. The project consists of eight granted exploration licenses and one exploration license application in the Gabanintha Formation in the north of the Murchison granite-greenstone terrane of the Archaean Yilgarn Craton. The project has a mining licence application pending.

The Regional Location Map of the Gabanintha Vanadium Deposit in Mid West Western Australia is shown below:

  • High grade resource in favourable mining jurisdiction – Murchison, Western Australia. One of the highest-grade vanadium deposits being advanced globally
  • The Mineral Resource includes a distinct massive magnetite high-grade zone of 93.6 Mt at 1.00% V2O5 consisting of:
  • Measured Mineral Resource of 10.1Mt at 1.11% V2O5,
  • Indicated Mineral Resource of 4.9Mt at 1.09% V2O5, and
  • Inferred Mineral Resource of 78.6Mt at 0.98% V2O5.
  • Deposit is at surface suitable for open pit operation and open at depth
  • Total Mineral Resource 175.5Mt at 0.77% vanadium pentoxide (V2O5) consisting of:
  • Measured Mineral Resource of 10.1Mt at 1.11% V2O5,
  • Indicated Mineral Resource of 24.0Mt at 0.63% V2O5, and
  • Inferred Mineral Resource of 141.4Mt at 0.77% V2O5.

 

Deposit identified over 11km drilled strike length

Metallurgical Test Work

  • Metallurgy and economics focused on opportunities presented by exceptional high grade ore horizon (92Mt at 0.96% V2O5, 15Mt at 1.05% V2O5 Measured and Indicated Ore)
  • Fresh ore high mass recovery (73%), extracting 92.3% of vanadium in a low silica (0.55%) magnetic concentrate grading 1.42% V2O5
  • Transition ore high mass recovery (67%), extracting 87% of vanadium in a good silica (1.68%) magnetic concentrate grading 1.45% V2O5
  • Concentrate grades up to 1.72% and 1.66 % achieved, indicating significant upside available from the ongoing test work optimization
  • Strong recoveries achieved from coarse grind sizes of P80 106 µm, scope to maintain low operating costs
  • Low silica in concentrate offers significant downstream operating cost benefits
  • Focus on conventional vanadium roast-leach technology for processing as used in all world operating Fe-V-Ti projects (Rhovan, Vametco, Largo)

      

Metallurgical Test Work – Sulphide

  • Cobalt, Nickel and Copper in a sulphide concentrate recovered from non-magnetic stream in bench-scale tests on fresh high-grade massive magnetite at Gabanintha.
  • Sulphide concentrates produced from flotation containing 3.8 to 6.3% of base metals including 1.54 to 2.02% Cobalt, 1.36 to 2.58% Nickel and 0.82 to 1.70% Copper.
  • Sulphide recovery circuit to be evaluated as part of the PFS processing flowsheet.
  • Sale of a by-product Cobalt, Nickel and Copper sulphide concentrate has potential to increase revenue at Gabanintha.
  • Resource estimate on base metals currently being conducted.
