Metals Australia has established a maiden 45.7Mt Inferred VTM resource at Manindi West, alongside test work producing titanium oxide above 99% purity. The opportunity is sizeable, but remains an early-stage resource supported by conceptual expansion targets and screening-level economics.
- 45.7Mt Inferred resource at 9.4% TiO₂, 0.25% V₂O₅ and 21% Fe
- Conceptual Exploration Target of 67Mt to 89Mt
- Hydrometallurgical test work produced >99.05% TiO₂ and >97.98% Fe₂O₃
- Manindi VTM resource sits 1km from the existing Zn-Cu-Ag resource
- Further drilling and integrated bench-scale processing tests planned
Maiden resource establishes Manindi West as a VTM project
Metals Australia Limited (ASX:MLS) has put a number on the Manindi West vanadium-titanium-magnetite opportunity, reporting a maiden Inferred Mineral Resource of 45.7 million tonnes grading 9.4% titanium oxide, 0.25% vanadium oxide and 21% iron. At the company’s stated 4% TiO₂ cut-off, that equates to about 4.3Mt of contained TiO₂, 0.1Mt of V₂O₅ and 9.6Mt of iron.
The deposit extends for approximately 1,250 metres along strike and has been modelled from surface to 260 metres below surface. The 2025 reverse-circulation programme intersected thick VTM mineralisation in 13 of 14 holes, with the company describing the mineralisation as open along strike and at depth.
Exploration target adds scale but not resource certainty
The reported resource sits inside a conceptual Exploration Target of 67Mt to 89Mt grading between 8.2% and 11.9% TiO₂, 0.20% and 0.29% V₂O₅, and 19.5% and 23.5% iron. That target is based on magnetic data, mapping and limited drilling rather than a resource estimate, and the announcement explicitly cautions that further work may not result in any of it being converted to a Mineral Resource.
Four additional magnetic “look-alike” targets extend across roughly another four kilometres of strike. Only one of those areas has been drilled: hole MWRC014 at Target 2 intersected similar magnetite-ilmenite mineralisation, but the company has not estimated an Exploration Target or Mineral Resource for the broader targets. Further RC and diamond drilling is subject to funding, approvals, land access and rig availability.
Processing tests point to a higher-value titanium route
The more distinctive part of the announcement is the processing work. Stage 1 leaching of an ilmenite-rich sample extracted 91.5% of contained TiO₂ and 82.5% of contained iron within six hours. Stage 2 work then produced iron oxide containing more than 97.98% Fe₂O₃ and titanium oxide containing more than 99.05% TiO₂ through solvent extraction and hydrolysis.
Those results came from a 117-kilogram composite sample rather than representative bulk-scale material, so they demonstrate process response rather than commercial production. Earlier magnetic-separation work produced a 66% iron concentrate carrying 1.19% V₂O₅ and a separate concentrate grading 43.8% TiO₂, with combined recoveries of 87.8% iron, 84.0% TiO₂ and 91.9% V₂O₅.
Adjacent zinc resource broadens the development question
Manindi West sits about one kilometre from Metals Australia’s existing Zn-Cu-Ag resource, which the company says contains 1.08Mt at 6.52% zinc, 0.26% copper and 3.19 grams per tonne silver. The zinc resource includes Measured, Indicated and Inferred material, unlike the new VTM estimate, which is entirely Inferred.
Metals Australia is assessing standalone and integrated development options for the two deposits, as well as potential ore sales, strategic partnerships, joint ventures and partial or full divestment of the zinc asset. The company says it is also reviewing historical drilling and submitting representative material for ore-sorting assessment, but no development decision is disclosed.
Inferred classification leaves technical work ahead
The economic case remains deliberately preliminary. A screening-level RPEEE assessment used assumptions including a 2.25 million tonne per year plant, about 1.1 million tonnes per year of concentrate, average operating costs of US$103 per tonne of concentrate and a weighted product price of US$175 per tonne. Metals Australia says these inputs are not production forecasts, guidance or the results of a formal scoping, pre-feasibility or feasibility study.
The next tests are therefore practical rather than rhetorical: infill drilling to improve the resource classification, re-assaying to address identified limitations in four-acid digestion, and integrated bench-scale metallurgical work using representative MRE material. Until those steps are complete, the headline scale and purity results offer a promising development direction, but not yet a mine plan.
Bottom Line?
Manindi now has a meaningful resource and an intriguing downstream processing result; the investment case turns on whether both survive representative testing, tighter drilling and formal economic studies.
Questions in the middle?
- Can the high-purity TiO₂ and Fe₂O₃ results be reproduced from representative resource-scale material?
- How much of the 67Mt to 89Mt Exploration Target can be converted into higher-confidence resources?
- Will Metals Australia pursue a standalone VTM project, an integrated Manindi development or a strategic transaction?
