Ausmon’s Jabuk Results Signal Potential Challenges Ahead for Land Access
Ausmon Resources reports promising rare earth element assay results from its Jabuk Prospect in South Australia, revealing concentrations up to 1,452 ppm TREO. The company plans an extensive grid drilling program to further define this emerging mineralisation.
- Significant TREO assays up to 1,452.73 ppm from September 2025 aircore drilling
- Planned 10 km grid drilling over Jabuk Prospect to refine mineralisation footprint
- Limestone Coast Project spans 2,523.7 km² with three key prospects – Jabuk, Geranium, Beelitz
- Results support further exploration and community engagement for land access
- Nearby Australian Rare Earths’ Koppamurra project highlights regional potential
Encouraging Assay Results from Jabuk
Ausmon Resources Limited has released laboratory assay results from its September 2025 aircore drilling campaign at the Jabuk Prospect, part of its Limestone Coast Project in South Australia. The assays reveal total rare earth element (TREO) concentrations reaching as high as 1,452.73 parts per million (ppm), a notable figure for early-stage exploration in this region.
The drilling program comprised 23 vertical aircore holes totaling 418 meters, with 24 samples exhibiting elevated rare earth element levels between 130 ppm and 1,452 ppm. These results were confirmed through comprehensive laboratory analysis at ALS Adelaide, moving beyond initial handheld XRF readings to provide a more complete geochemical profile.
Strategic Expansion Plans
Buoyed by these promising results, Ausmon plans to undertake a grid-based aircore drilling program across a 10-kilometer area within the Jabuk Prospect. The proposed grid will cover 250 by 400 meters with drill holes extending to a maximum depth of 20 meters. This systematic approach aims to delineate the extent and continuity of the rare earth mineralisation, providing critical data for future resource estimation.
Importantly, the company is preparing to engage with local landholders and communities to secure access agreements, a necessary step given that upcoming drilling will extend onto freehold land. These consultations, scheduled for late 2025 and early 2026, underscore Ausmon’s commitment to responsible exploration practices.
Regional Context and Prospects
The Limestone Coast Project encompasses three main prospects, Jabuk, Geranium, and Beelitz, spanning a combined area of 122 square kilometers within a broader 2,523.7 square kilometer tenement package. The project targets the Loxton-Parilla sands of the Murray Basin, known for their rare earth element potential.
Ausmon’s exploration efforts align with broader regional activity, notably Australian Rare Earths’ nearby Koppamurra project, which boasts a JORC-compliant resource of 236 million tonnes at 748 ppm TREO. This proximity highlights the Limestone Coast as a burgeoning rare earths province with significant upside potential.
Looking Ahead
The company’s Chief Technical Officer has expressed optimism about the initial drilling outcomes and the planned grid drilling’s ability to enhance understanding of mineralisation patterns. Combined with previous drilling campaigns in 2024 and earlier in 2025, these results build a compelling case for continued investment in exploration activities across the tenements.
As Ausmon advances its exploration strategy, the coming months will be critical in translating these early assay successes into a defined resource, while navigating community engagement and operational logistics.
Bottom Line?
Ausmon’s next drilling phase and community outreach will be pivotal in unlocking the Limestone Coast’s rare earth potential.
Questions in the middle?
- How will community consultations impact the timeline for expanded drilling on freehold land?
- What are the implications of these assay results for potential resource estimation and project economics?
- How does Ausmon plan to differentiate its Limestone Coast Project amid increasing regional rare earth activity?
