Ausmon Resources has released amended drilling results from its Beelitz Prospect in South Australia, highlighting encouraging preliminary rare earth element concentrations and outlining plans for further exploration.
- 20 vertical aircore holes drilled at Beelitz Prospect totaling 364 meters
- Preliminary pXRF results show significant concentrations of key rare earth elements
- 42 samples submitted for comprehensive laboratory assays to confirm grades
- Previous drilling in 2024 and 2025 yielded notable Total Rare Earth Oxide (TREO) results
- Next steps include land access negotiations and grid-based infill drilling
Exploration Update at Beelitz Prospect
Ausmon Resources Limited has provided an amended update on its rare earth elements (REEs) exploration at the Beelitz Prospect, located within the Limestone Coast region of South Australia. The company completed a road verge aircore drilling program in February 2026, comprising 20 vertical holes averaging 18 meters in depth, totaling approximately 364 meters of drilling. This program aimed to refine target areas for future, more detailed grid-based drilling to support resource estimation efforts.
The announcement replaces an earlier release from February 24, 2026, adding revised JORC tables, cross-section diagrams, and location maps for drill holes, but contains no new material information beyond these technical enhancements.
Preliminary pXRF Results Show Encouraging REE Concentrations
Partial results from portable X-ray fluorescence (pXRF) analysis reveal promising concentrations of five key rare earth elements, cerium, praseodymium, lanthanum, neodymium, and yttrium, with selected intervals showing up to 495 ppm TREE (Total Rare Earth Elements). Notably, hole 26BZAC014 returned 2 meters at 332 ppm TREE, including 1 meter at 495 ppm. These pXRF results serve as a preliminary indication and are not a substitute for full laboratory assays, which are pending.
In total, 46 samples, including quality control specimens, have been dispatched to ALS Laboratories in Adelaide for comprehensive geochemical analysis covering the full suite of 14 REEs. The forthcoming assay results will be converted to oxide values to calculate Total Rare Earth Oxide (TREO) concentrations, a critical metric for assessing the economic potential of the deposit.
Context of Prior Drilling and Regional Potential
This latest drilling complements previous programs conducted in 2024 and 2025 across the Limestone Coast tenements, including Parrakie, Wilkawatt, and Peake. Earlier aircore drilling yielded significant TREO intercepts, with some assays exceeding 1,200 ppm TREO over one-meter intervals. These results underscore the potential of the Loxton-Parilla Sands formation as a host for REE mineralisation.
Australian Rare Earths, operating nearby, has reported a JORC-compliant resource of 236 million tonnes at 748 ppm TREO, highlighting the broader regional prospectivity and strategic importance of the area for rare earth exploration.
Next Steps and Strategic Outlook
Ausmon’s Chief Geologist expressed optimism about the recent results and indicated ongoing discussions to undertake grid-based shallow aircore drilling at Beelitz and/or the Jabuck Prospect. These efforts will focus on delineating resource potential with greater precision.
Future work will involve negotiating land access agreements with local landholders, conducting community engagement to secure support, and planning infill drilling within accessible freehold land parcels. The company’s methodical approach, combining pXRF screening with laboratory assays and detailed geological logging, aims to build a robust foundation for resource estimation and potential development.
While the pXRF results are encouraging, the company cautions that these preliminary readings require confirmation through laboratory assays before any definitive conclusions about mineralisation grades and widths can be drawn.
Bottom Line?
Ausmon’s Beelitz drilling sets the stage for critical assay results that will shape the next phase of rare earth exploration in South Australia.
Questions in the middle?
- How will the upcoming ALS laboratory assay results compare with the preliminary pXRF data?
- What are the timelines and funding plans for the proposed grid-based infill drilling?
- How might community and landholder negotiations impact the pace of exploration activities?
