Basin Energy Confirms Thick High-Grade Rare Earths at Newmans Prospect

Maiden Drilling Uncovers Significant Rare Earth Mineralisation

Basin Energy Limited (ASX:BSN) has delivered a promising start to its maiden reverse circulation drilling program at the Newmans Prospect in northwest Queensland, confirming thick, shallow, and high-grade rare earth mineralisation. Drillhole SBRC26003 stood out, returning 18 metres at 401 ppm combined neodymium and praseodymium (NdPr) oxide and 49 ppm dysprosium and terbium (DyTb) oxide from surface within 2,160 ppm total rare earth oxide (TREO). Notably, within this interval, a 3-metre section from 12 metres depth graded 603 ppm NdPr oxide and 109 ppm DyTb oxide within 3,613 ppm TREO, highlighting the potential for valuable heavy rare earth elements near surface.

Preserved Weathering Zones Drive New Geological Model

These results support Basin’s evolving interpretation that the preservation of weathering profiles above fertile rare earth-bearing granites is critical for enhanced near-surface REE enrichment at Newmans. The first two holes, SBRC26001 and SBRC26002, intersected fertile granites but lacked significant preserved weathering and returned limited mineralisation. In contrast, SBRC26003 retained a broader, strongly weathered profile correlating with its superior assay results. Drillhole SBRC26006, pending assays, intersected the most extensive preserved weathering profile, considered a pivotal test of this emerging geological model. This shift from targeting fresh granite to preserved weathering zones marks a strategic refinement in Basin’s exploration approach.

Strategic Location within Emerging Critical Minerals Hub

Newmans lies within the Sybella Batholith, a major granite system also hosting Red Metal Limited’s (ASX:RDM) Sybella rare earth discovery 20 kilometres north. The prospect is situated just 40 kilometres from Mount Isa, which is rapidly gaining recognition as a critical minerals district. Basin holds a substantial 5,805 square kilometres of tenure in this region, with additional REE anomalies identified at Eight Mile and Three Ways, presenting multiple drill-ready targets. The company’s Managing Director, Pete Moorhouse, emphasised the broader implications of the preserved weathering model for exploration across the Sybella Batholith, which could unlock further discoveries in this strategic corridor.

Funding Secured for Accelerated Exploration

Basin is well positioned to advance its Newmans program following a recent A$1.1 million strategic placement, led by uranium-focused investors, which supports follow-up drilling and geophysical work. This funding milestone ensures the company can integrate the remaining assay results, expected by mid-June, with geological data, satellite imagery, and mapping to refine its preserved weathering model. Planned next steps include mineralogical and metallurgical assessments leveraging archived samples, ranking preserved weathering targets, and evaluating additional prospects within the Sybella-Barkly Project. This financial backing follows Basin’s earlier capital raising efforts and asset rationalisation moves to streamline its portfolio and focus on high-potential critical minerals assets A$1.1M strategic placement district-scale rare earth potential.

Awaiting Full Assay Suite to Confirm Extent

While the initial results from three drillholes are encouraging, assays from the remaining five holes are pending and will be critical to validating the scale and continuity of mineralisation at Newmans. True widths of mineralisation remain unconfirmed due to the early stage of exploration, and ongoing work will be needed to understand the geometry and economic potential of the preserved weathering zones. Basin’s Exploration Manager, Odile Maufrais, highlighted that the program’s evolution from testing granite fertility to focusing on weathered granite systems underscores the dynamic nature of exploration at this stage. The company’s ability to integrate multidisciplinary data sets will be key to refining targeting and advancing the project efficiently.
