Barkly Rare Earths Expands Mineralisation Footprint in Northern Territory
Exploration success extends mineralisation eight kilometres further, boosting potential for large-scale rare earth resource development.
1Exploration Success at Barkly
Barkly Rare Earths has achieved significant mineralisation in 13 of 16 additional holes at its Northern Territory project. This phase-one campaign, spanning 10,000 metres, has successfully extended known mineralisation boundaries by eight kilometres. Currently, 56 of 60 assayed holes have returned positive results, demonstrating a strike rate exceeding 93 per cent across 23km.
2Resource Expansion Targets
The project currently holds an inferred resource of 40 million tonnes at 2100 ppm TREO. Management aims for a massive expansion, targeting between 200 million and one billion tonnes. With 15km of untested ground between northern and southern deposits, the company is actively deploying resources to bridge these gaps and confirm total scale.
3High-Grade Intercept Details
Recent assays reveal high-grade TREO concentrations, particularly in the southern reaches. One standout hole returned 1.5 metres at 2171 ppm TREO from a shallow 10.5 metres depth. This included a 0.5-metre section grading 4550 ppm TREO and 1678 ppm MREO, highlighting the project's potential for delivering high-value magnet rare earth oxides.
4Northwest Drilling Breakthrough
Drilling eight kilometres northwest of previous intercepts confirmed significant mineralisation in five of eight holes. The widest intercept to date reached 5.5 metres at 1035 ppm TREO and 343 ppm MREO from 22 metres downhole. Managing director Craig Wright noted these results provide strong confidence in the project's overall scale and lateral extent.
5Deposit Characteristics and Quality
The deposit remains shallow and flat-lying, with mineralisation found between the surface and 38 metres depth. Magnet rare earth oxides comprise 29 to 38 per cent of the total rare earth oxides, consistent with previous findings. Crucially, radioactive elements like uranium and thorium remain at very low levels, potentially simplifying future processing requirements.
6Strategic Geopolitical Context
These findings arrive as Australia and its allies intensify efforts to secure critical mineral supply chains outside of China. The Federal Government is already supporting projects like Arafura’s Nolans site with A$1.2 billion in backing. Barkly’s progress aligns with broader national strategies to build alternative, reliable sources for essential high-strength magnet materials.
7Operational Scaling Plans
Barkly has drilled 89 holes totaling 2168 metres, with 26 additional samples currently undergoing laboratory analysis. The company is now tendering for a second drill rig to accelerate exploration efforts. Furthermore, concentration and extraction testwork is underway, with a formal mineral resource update scheduled for release in the fourth quarter of this year.
8Project Scale and Outlook
With a mineralised footprint stretching over 23 kilometres, Barkly is systematically building a case for a project of significant scale. The combination of high strike rates and favorable metallurgical characteristics positions the company well within the global market. Investors are now awaiting further data to determine the ultimate size of this deposit.
