Barkly Rare Earths has added 13 significant rare earth intercepts from 16 holes at its Northern Territory project, extending confirmed mineralisation across 23km. The results strengthen the case for a larger resource, although the next test is whether pending assays translate that continuity into a materially bigger estimate.
- 13 of 16 new holes returned significant rare earth intercepts
- 56 of 60 reported holes now contain mineralisation across 23km
- Best new interval included 0.5m at 4,550 ppm TREO
- Northwest hits sit 6-8km from earlier results and outside the Exploration Target
- Resource update remains targeted for Q4 2026, subject to assays and drilling progress
Northwest drilling extends Barkly’s rare earth footprint
Barkly Rare Earths Limited (ASX:BAK) has pushed its Barkly rare earths story into new ground, with five of the first eight northwest holes returning significant intercepts 6-8km from earlier results. Four of those holes sit outside the company’s Exploration Target, although that target remains conceptual and is not a Mineral Resource.
The latest batch adds 13 significant intercepts from 16 holes, taking the total to 56 of 60 reported holes. Mineralisation has now been identified across as much as 23km, with high-grade intervals, defined by single 0.5-metre assays of at least 2,500 ppm TREO, present in 36 holes. That compares with the 43 of 44 mineralised holes reported in the previous results batch, which also covered the same 23km trend.
Best new grades came from southern resource drilling
The strongest new result came from southern hole BAK0032: 1.5 metres at 2,171 ppm total rare earth oxide, including 0.5 metres at 4,550 ppm TREO. BAK0034 returned 1.5 metres at 1,997 ppm TREO, including 0.5 metres at 4,529 ppm, while BAK0021 delivered a 0.5-metre high-grade interval at 4,355 ppm TREO.
All eight southern holes produced significant intercepts, including holes within and around the southwestern portion of the existing Inferred Mineral Resource. In the northwest, the standout was BAK0284, which returned the widest Phase 1 intercept reported so far: 5.5 metres at 1,035 ppm TREO from 22 metres.
Magnet rare earth ratio remains consistent
The new intercepts also preserved the composition Barkly is seeking. Magnet rare earth oxides represented 29% to 38% of TREO across all 13 new intercepts, broadly consistent with the 34% MREO ratio in the existing 40 million tonne Inferred Mineral Resource, which grades 2,100 ppm TREO.
Uranium and thorium remained low in the new intervals at 1-3 ppm and 5-11 ppm respectively. Barkly says those elements can be important cost drivers in processing flowsheets, but the announcement reports exploration results rather than an economic study or production outcome. Four intercepts across the programme also contain elevated yttrium, with the company continuing to investigate the potential for additional heavy rare earths.
Pending assays will determine the scale of the resource case
Barkly has drilled 89 holes for 2,168 metres, including six redrills, with assays from 26 holes at or being prepared for the laboratory. Drilling resumed on 5 October after downtime awaiting replacement parts, and 18 further holes had been completed by 15 October. The company is tendering for a second rig, which Managing Director Craig Wright said could help build out the resource faster.
The company is targeting an updated Mineral Resource estimate in the fourth quarter of 2026, subject to drilling and laboratory progress. That estimate will have to convert a strong exploration hit rate into a defensible assessment of tonnes, grade continuity and metallurgy. Until then, the 200-1,000Mt Exploration Target remains an indication of geological potential, not a quantified resource.
Bottom Line?
The drilling continues to validate a broad, shallow and compositionally consistent rare earth system; the decisive catalyst is whether the pending assays support a materially larger Mineral Resource.
Questions in the middle?
- Will the remaining assays confirm continuity outside the current Inferred Mineral Resource and conceptual Exploration Target?
- Can Barkly secure a second rig without extending the timetable for its Q4 2026 resource update?
- Will metallurgical and geometallurgical testwork support the low uranium and thorium profile as a practical processing advantage?
