Ausmon Resources has reported encouraging partial pXRF results from its recent drilling program at the Beelitz Prospect in South Australia, highlighting potential for rare earth elements. Full laboratory assays are underway to refine resource estimates and guide future exploration.
- 20 vertical aircore holes drilled at Beelitz Prospect, Limestone Coast
- Partial pXRF results show significant concentrations of key rare earth elements
- 46 samples sent for comprehensive laboratory analysis at ALS Adelaide
- Results follow positive drilling outcomes at nearby Jabuck Prospect
- Plans for further grid-based drilling pending assay results and land access
Ausmon Advances Rare Earths Exploration in Limestone Coast
Ausmon Resources Limited has released partial results from a recent drilling campaign targeting rare earth elements (REEs) at its Beelitz Prospect, located within the Wilkawatt and Peake tenements in South Australia's Limestone Coast. The program comprised 20 vertical aircore holes averaging 18 metres depth each, drilled along road verges to refine the understanding of REE mineralisation in the region.
The initial pXRF (portable X-ray fluorescence) readings focused on five critical REEs; cerium, praseodymium, lanthanum, neodymium, and yttrium; revealing encouraging concentrations, with some intervals reaching up to 400 ppm TREE (total rare earth elements). These preliminary findings build on Ausmon's prior positive results at the Jabuck Prospect, signalling a consistent mineralisation trend within the company's tenements.
Comprehensive Laboratory Analysis Underway
To validate and expand upon the pXRF data, Ausmon has dispatched 46 samples, including quality control duplicates, to the ALS laboratory in Adelaide for detailed geochemical analysis using the ME-MS81 method. This technique will provide a full suite assay of all 14 rare earth elements, converting elemental concentrations into oxide equivalents to calculate Total Rare Earth Oxide (TREO) values; an industry standard metric crucial for resource assessment.
These forthcoming results will be instrumental in delineating high-priority zones within Beelitz for more intensive grid-based drilling, a step that could significantly advance the project's resource definition and economic potential.
Strategic Context and Next Steps
Ausmon's exploration efforts occur amid a broader regional surge in rare earths interest, with neighbouring Australian Rare Earths reporting a substantial JORC-compliant resource of 236 million tonnes at 748 ppm TREO nearby. This regional momentum underscores the strategic importance of the Limestone Coast as a prospective rare earth province.
Looking ahead, Ausmon plans to engage with landholders and local communities to secure access for expanded drilling programs. The company is also evaluating whether to focus grid drilling on Beelitz, Jabuck, or both prospects, depending on the upcoming assay results and logistical considerations.
Chief Geologist Mark Derriman emphasised the encouraging nature of the current results and the methodical approach Ausmon is taking to advance its exploration pipeline responsibly and efficiently.
Bottom Line?
Ausmon’s next assay results will be pivotal in shaping the future of rare earth exploration in South Australia’s Limestone Coast.
Questions in the middle?
- Will the full ALS assay results confirm and exceed the encouraging pXRF findings?
- How will Ausmon prioritise drilling between Beelitz and Jabuck prospects based on upcoming data?
- What timelines and funding strategies will Ausmon adopt for the next phase of exploration?
