Ore Resources Extends Lithium Mineralisation at Kangaroo Hills with Strong Drilling Results

Drilling Confirms Substantial Extensions at Big Red and Potoroo

Ore Resources Ltd (ASX:OR3) has delivered a solid boost to its Kangaroo Hills Lithium Project in Western Australia with assay results from a 3,300-metre Reverse Circulation (RC) drilling campaign. The programme, completed across April and May 2026, successfully extended lithium mineralisation at both the Big Red and Potoroo pegmatite systems, two key targets within the broader Coolgardie Lithium Projects.

Highlight intercepts from the Big Red system include 34 metres at 1.11% lithium oxide (Li2O) starting from 77 metres, featuring a higher-grade 14-metre section at 1.63% Li2O. Other notable results include 18 metres at 1.03% Li2O and 28 metres at 0.89% Li2O, confirming consistent grades and widths over a 500-metre northeast-southwest strike. Meanwhile, Potoroo drilling extended mineralisation by 50 metres northwards, with intercepts such as 8 metres at 1.08% Li2O, maintaining an open-ended north-south strike.

Big Red Pegmatite Shows Continuity and Open Extensions

Big Red remains the focus of the drilling efforts, characterised by thick, laterally continuous pegmatite mineralisation with strong lithium grades. The recent step-out drilling north of previous 2024 lines confirmed a 60-metre extension, with intercepts like 12 metres at 1.05% Li2O and 10 metres at 1.02% Li2O encountered at depths exceeding 140 metres. A further drill hole 150 metres north intersected spodumene-bearing pegmatites, albeit at lower grades, suggesting the higher-grade zone is likely shifting northeast and remains open for follow-up.

These results bolster confidence in the continuity of Big Red’s mineralisation across central and southern zones, underpinning its potential as a substantial lithium resource. The company notes that further work is needed to delineate higher-grade zones and thickening mineralisation to the north.

Potoroo Pegmatite’s Growth Potential Reinforced

At Potoroo, drilling extended the pegmatite strike by 50 metres north and 90 metres west, with intercepts including 8 metres at 1.08% Li2O and 4 metres at 1.01% Li2O respectively. This system remains underexplored but exhibits a clear north-south orientation that highlights its potential for further growth within the Kangaroo Hills tenure.

Ore Resources’ technical director Robin Cox emphasised the significance of these extensions, noting the complementary relationship between Potoroo and Big Red within the lithium-caesium-tantalum (LCT) pegmatite system that defines Kangaroo Hills.

Advancing Commercialisation Amid Improving Market Conditions

With lithium market conditions showing signs of improvement and regional activity intensifying, Ore Resources is actively assessing near-term development and commercialisation pathways for Kangaroo Hills. Options under consideration include export direct shipped ore (DSO) and domestic ore sales, positioning Kangaroo Hills as one of the few lithium projects in Australia without existing development, production, or binding offtake agreements.

The company is well funded with A$9.6 million cash and zero debt as of 31 March 2026, providing a strong financial platform to progress exploration and evaluation work across its Coolgardie and Kal East Lithium and Gold Projects.

Planned Exploration and Metallurgical Work for H2 2026

Looking ahead, Ore Resources plans to ramp up lithium-focused activities in the second half of 2026. This includes additional drilling at Big Red and Potoroo to further define mineralisation, first-pass drill testing of regional targets within Kangaroo Hills, follow-up metallurgical test work to support project advancement, and initial drilling at the Miriam Lithium Project.

Managing Director Nick Rathjen highlighted the drilling programme’s success in expanding the mineralised footprint and improving geological confidence, setting the stage for unlocking value in the near term. Updates on exploration progress and development options are expected in the coming weeks.
