West Arunta Portfolio
The West Arunta Region has emerged as one of Australia’s most exciting new critical mineral exploration frontiers, brought to global attention in 2022 with the discovery of world-class niobium deposits. Located in the Northern Territory, about 400 km north west of Alice Springs near the WA border, this vast and underexplored terrain is geologically comparable to some of the world’s leading mineral provinces in Canada and Africa.
URO holds four granted titles and one application across more than 2,300 km², covering both pastoral and Aboriginal freehold land. Our 100%-owned tenure sits on Mount Doreen cattle station and is highly prospective for a diverse suite of commodities including beryllium, tin, antimony, bismuth, copper, tungsten, fluorine, gold, lithium, molybdenum, rare earth elements, rubidium, silver, uranium, and zinc.
For investors, West Arunta offers a rare combination: the stability of Australia’s mining-friendly Northern Territory, the scale of an underexplored Proterozoic province, and the potential for transformative discoveries. With advanced tools such as hyperspectral imaging, deep geochemistry, and cutting-edge geophysics, explorers are now seeing beneath the cover for the first time, unlocking opportunities across the energy transition, defence, and technology supply chains.
As global demand for critical minerals accelerates, URO’s West Arunta portfolio stands as one of the most compelling growth opportunities in Australian exploration today.
BERYLLIA
Location: West Arunta, Northern Territory, Australia
The Beryllia Project is URO Corporation’s flagship critical minerals exploration initiative, located in the Northern Territory on the vast Mt Doreen cattle station. Situated in the favourable geodynamic setting of the West Arunta Province, the Beryllia project is positioned in a stable jurisdiction with exceptional geology and infrastructure access — just hours from Alice Springs and the port of Darwin.
The project targets high-value beryllium and tin, with associated critical minerals within the Southwark Granite Suite, known for hosting rare earths, lithium, rubidium and fluorine-rich systems. The beryllia project has the potential to address a single supply chain risk and offer a crucial alternate source of high-grade beryllium, vital for defence, aerospace and advanced electronics industries.
The Right Geology. The Right Chemistry. The Right Time.
Project Highlights
-
World-class Beryllium prospect in bertrandite minerals – up to 1.22% BeO

Tin-rich greisen – up to 2.4% Sn in cassiterite
-
Surface lithium of up to 2,081 ppm
-
Fluorite-rich granites – up to 19% fluorine
-
High-grade copper, zinc, bismuth, antimony, rubidium & rare earth elements
-

Hyperspectral Survey Insights
A 40,000-acre hyperspectral geophysical survey, utilising both VNIR (Visible and Near Infrared) and SWIR (Shortwave Infrared) imaging revealed spectral variation and mineralogical signatures across the project area.
Key survey outputs include:
-
Mineral abundance and alteration maps
-
Bertrandite and muscovite halo indexing
-
Fluorspar identification
-
Geological structure interpretation to guide future exploration
The hyperspectral results are being used to prioritise drill targets, refine lab assay calibration, and enhance the geological understanding of the Beryllia mineral system.
WILSON'S FIND
Location: West Arunta, Northern Territory, Australia
The Wilson’s Find Copper-Tungsten Project is a promising critical minerals discovery located 380 km northwest of Alice Springs in the West Arunta Province, Northern Territory. Hosted within the Wabudali Granite, the project has returned high-grade copper, tungsten, and silver, along with zinc, molybdenum, beryllium, and other critical minerals. URO’s exploration to date includes surface sampling, a gradient IP survey, an 8-hole RC drilling program and laboratory assay results, all confirming a structurally controlled, multi-zone polymetallic system.
Geophysical and drilling results have outlined significant mineralisation at depth, with intercepts such as 4,445 ppm copper and 5,694 ppm tungsten. With a well-defined geological setting and strong exploration upside, URO Corporation is now advancing Wilson’s Find through further geophysics, resource modelling, and follow-up drilling. The project offers substantial potential as a new critical minerals source in a stable, underexplored region of Australia.
Project Highlights
-
High-grade surface samples
-
Copper up to 15.9%, tungsten up to 2,038 ppm (with specimen-grade wolframite >27%), and silver up to 120 ppm.
-
-
Polymetallic anomolies
-
Presence of zinc, lead, uranium, beryllium, and molybdenum confirmed in surface assays.
-

-
-
RC drilling (October 2024)
-
All 8 holes intersected multiple mineralised zones, confirming a structurally controlled polymetallic system.
-
Drill intercepts include:
-
4,445 ppm copper, 5,694 ppm tungsten, and 290 ppm beryllium
-
1.05% copper in 4m zone
-
Up to 3,046 ppm tungsten, 2,000 ppm zinc, 503 ppm molybdenum, and 15 g/t silver

SOUTHWARK SHEAR ZONE
Location: West Arunta, Northern Territory, Australia
The Southwark Shear Zone (SSZ) Project is highly prospective for rare earth elements (REE) and kaolin clay located in the underexplored West Arunta Region.
The SSZ lies within the Aileron Province, on the southern margin of the North Australia Craton in a proven mineralised belt hosting critical minerals such as niobium, uranium, gold, copper, lead, zinc, and tungsten.
The SSZ is underlain by Southwark Granite Suite rocks, highly enriched in REEs, and partially covered by Quaternary regolith and palaeovalley sediments. These have been heavily weathered, producing thick kaolin-rich clay profiles with ionic adsorption REE mineralisation, similar to South China’s world-leading regolith-hosted REE deposits.
Project Highlights
-
21-hole aircore drilling program (Aug 2023) confirmed high-grade rare earth element (REE) mineralisation and thick kaolin zones
-
Best intersection: 6 m @ 5,229 ppm TREO (20% NdPr)
-
Peak grade: 2 m @ 12,631 ppm TREO (1.26%)
-
Over 50% of holes returned >1,000 ppm TREO
-
Up to 20 m of bright white kaolin clay with coinciding REE enrichment
With proven high-grade results and a favourable geological setting, the project offers both near-term exploration upside and long-term development potential.
