Charley Creek Portfolio

URO’s Charley Creek Portfolio spans nearly 1,400 km² of highly prospective ground in the Northern Territory, strategically positioned across four project areas – Glen Helen, Hann Range, MacDonnell Range, and Tanami. Together, these projects offer exposure to a diversified suite of commodities including rare earths, uranium, gold, base metals, and critical minerals.

Set within proven mineral provinces that already host major discoveries like Nolan’s Bore (REEs), Napperby (uranium), and Charley Creek (ionic clay REEs), URO’s projects remain largely underexplored yet demonstrate outstanding early results. From high-grade rare earth samples in the MacDonnell Range, to untested skarn systems at Glen Helen, gold-bearing structures in the Hann Range, and shallow uranium potential at Tanami, the portfolio provides multiple discovery pathways across some of Australia’s most mineral-rich terrains.

With modern exploration underway and several compelling targets already identified, URO’s Charley Creek Portfolio offers investors a rare multi-commodity exploration opportunity in a stable jurisdiction, positioning the company to make the next major mineral discovery in Central Australia.

Hann Range

HANN RANGE

Location: Aileron, Northern Territory, Australia

URO’s Hann Range Project is located 125 km north of Alice Springs, just west of the Stuart Highway and 23 km south of Arafura Rare Earths’ Nolans Bore deposit. The licence covers the Hann Range, a prominent quartzite ridge overlying high-grade metamorphic basement, and lies within a structurally complex, highly prospective region of the Arunta Block.

The project offers a multi-commodity opportunity, with potential for gold, rare earth elements (REEs), uranium, nickel, chromium, base metals, iron, and niobium. Nearby historic Aileron Gold Reef demonstrates the area’s gold potential, while the Native Gap ultramafic intrusion confirms the prospectivity for nickel and chromium.

Recent URO field work has identified a prominent ridge south of the Hann Range, previously mapped as cover, now recognised as quartz-hematite-epidote altered rocks with cross-cutting quartz veins. The alteration style and geochemical signatures show strong parallels to Nolans Bore, suggesting both REE and critical mineral potential. Surface sampling has highlighted anomalous niobium, REEs, and base metals, confirming the ridge as a priority target for follow-up exploration.

EL33000 is largely underexplored, offering a high-impact greenfield opportunity with multiple mineralisation styles and strong regional analogues, positioning it as a key asset in URO’s Northern Territory exploration portfolio.

Project Highlights

Rock chip assays up to 38.8 g/t Au
pXRF anomalies: Nb 816 ppm, Ce 124 ppm, Nd 203 ppm, La 74 ppm
Iron up to 65%, nickel 1,559 ppm, barium 3,600 ppm
Uranium up to 216 ppm, silver 3.2 ppm, mercury 40 ppm
Strong Ba–Sr–P–REE signature paralleling Nolans Bore

Mountain REE

MOUNTAIN RARE EARTHS

Location: Eastern MacDonnell Ranges, Northern Territory, Australia

The MacDonnell Range Project is a high-potential rare earth element (REE) and critical minerals target, located in the MacDonnell Ranges, close to Alice Springs. Early work by URO has uncovered exceptional grades of rare earths and promising critical mineral signatures in this underexplored mountainous area.

Geologically, the project sits within lithologies known to host xenotime – a key source of heavy rare earths, particularly dysprosium – and intrusive dike swarms, which are interpreted as possible mineralisation hosts.

Project Highlights

Strong thorium radiometric anomalies identified.
Rock chip assays include:
0.1% Rb with elevated Zn & Co.
Nearby sample with 0.1% Co.
URO Mountain REE samples:
20.74% TREO (3.3% Nd, 0.98% Pr)
16.36% TREO (2.65% Nd, 0.78% Pr)
10.77% TREO (1.67% Nd, 0.46% Pr)
Presence of xenotime – a heavy REE mineral rich in dysprosium.
Anomalous Zn, Ag, Mo, Cr, and P in assays.

Glen Helen

GLEN HELEN

Location: Western MacDonnell Range, Northern Territory, Australia

The Glen Helen Project lies in the spectacular Western MacDonnell Ranges, a geologically rich terrain shaped by ancient mountain-building events and granitic intrusions. This project includes the Glen Helen and Stokes Yard prospects, both considered highly prospective for critical minerals.

Historic exploration has already revealed standout results zinc, lead, copper and silver. Mineralisation occurs in brecciated calc-silicate and marble units, pointing to a classic skarn or carbonate-replacement system linked to nearby Warumpi granitoids. These systems are known worldwide for hosting high-grade polymetallic deposits.

Despite these exceptional grades, Glen Helen remains underexplored. Past programs confirm widespread anomalous mineralisation but left key magnetic and structural targets untested. With modern exploration methods, URO has the opportunity to unlock the scale and continuity of this mineral system for the first time.

Set within a proven mineral province that also hosts the Nolan’s Bore rare earth deposit, the Glen Helen Project offers investors exposure to a high potential, underexplored polymetallic asset in one of Australia’s most stable jurisdictions.

Project Highlights

Prospective for Zn–Pb–Cu–Ag skarn and carbonate-replacement systems, linked to Warumpi granitoid intrusions.
Historical assays include standout results of:
- 35.8% Pb, 18.5% Zn, 3.5% Cu, 280 g/t Ag
- 12.2% Pb, 8.8% Zn in carbonate-replacement/skarn settings
- Rock chips up to 27.5% Zn
- Elevated bismuth and cadmium values associated with base metal mineralization
- Mineralisation hosted in calc-silicate, amphibolite and marble within a south-plunging synform; gossanous breccias extend over 60 m x 10 m.
Modern exploration URO confirmed widespread Pb–Zn–Cu anomalism and identified untested magnetic and structural targets.

TANAMI

Tanami

Location: Tanami, Northern Territory, Australia

URO’s Tanami Project sits in one of the Northern Territory’s most prospective mineral corridors, strategically located between world-class discoveries including Core Lithium’s Napperby uranium deposit, Arafura’s Nolan’s Bore REE-uranium project, and Enova’s Charley Creek ionic clay REE resource. This ground offers exceptional potential across multiple commodities yet remains significantly underexplored.

The project spans fertile basement rocks of the Aileron Province and their weathered cover sequences, creating opportunities for both basement-hosted systems and near-surface palaeochannel mineralisation. In the north, clear palaeochannel geometries mapped by airborne EM extend into URO’s ground from Napperby, providing a compelling analogue for shallow uranium and vanadium mineralisation. To the south, at Patty Well, regional-scale breccia dykes mark major fluid pathways along the Ngalia Basin margin, where historic reports of gold and sulphides are now supported by URO’s own drill results confirming base metal fertility.

Together, these elements position the Tanami Project as a standout multi-commodity exploration play—prospective for uranium, vanadium, REEs, gold, and base metals—all within a proven yet underexplored geological province.

Project Highlights

Uranium-Vanadium: Core Lithium’s Napperby deposit, immediately north of URO, hosts a JORC Inferred Resource of 9.54 Mt @ 382 ppm U₃O₈ for 8.03 Mlb U₃O₈, with a vanadium credit of 236 ppm V₂O₅. Untested palaeochannels mapped into URO’s ground offer direct extensions of this model.
Base Metals: URO’s 2023 aircore drilling intersected 1,116 ppm Zn at 21 m depth at Patty Well, confirming a fertile Zn-Pb-Cu-Ag system.
Gold Potential: Historic reports of gold near Patty Well and Mt Hammond highlight orogenic gold prospectivity in hematite-rich breccia zones.
Rare Earths: Nearby Nolan’s Bore and Charley Creek deposits demonstrate strong regional fertility for REE systems, both in hard rock and weathered profiles.
Geological Advantage: Rich, radiogenic Reynolds Range granites and regional structures provide multiple mineralisation styles within a single tenement package.
