Ausmon Plans 21-Hole Drilling Program to Probe Limestone Coast REE Deposits

Ausmon Advances Rare Earth Exploration

Ausmon Resources Limited has announced the commencement of a new drilling program targeting rare earth elements (REE) in the Limestone Coast region of South Australia. The campaign, scheduled to start imminently, will deploy 21 vertical aircore holes each drilled to a depth of 18 metres within the Parrakie EL 6795 tenement, focusing on the area designated LC003.

This initiative builds on Ausmon’s prior exploration efforts in 2024 and 2025, which involved broadly spaced road verge drilling across three key areas, LC001, LC002, and LC003. Those earlier programs successfully delineated a significant mineralisation trend spanning approximately 122 square kilometres, highlighting elevated concentrations of total rare earth oxides (TREO) and zirconium.

Strategic Focus and Methodology

The upcoming drilling will adopt a tighter grid spacing of 200 to 400 metres, a refinement from the previous 500 to 1000 metre intervals, enabling a more detailed assessment of mineralisation continuity and grade. The program’s initial phase targets road verges for logistical ease, with plans to extend drilling onto freehold land pending successful land access negotiations and community engagement.

Ausmon’s approach reflects a methodical progression from broad reconnaissance to focused resource definition, consistent with industry best practices. The company has engaged Speccy Science, a Perth-based consultancy, to oversee geological logging and ensure data quality aligns with JORC reporting standards.

Regional Context and Industry Comparisons

The Limestone Coast’s REE potential is underscored by nearby exploration success. Australian Rare Earths (ASX – AR3), operating just south of Ausmon’s tenements, recently reported a substantial JORC-compliant resource estimate of 236 million tonnes at 748 ppm TREO. This regional benchmark provides a promising backdrop for Ausmon’s exploration ambitions.

While Ausmon’s drilling results are pending, previous assays from the area have shown encouraging TREO grades, with some intervals exceeding 2,000 ppm. The presence of zirconium alongside REE adds further interest, potentially enhancing the economic viability of any future development.

Next Steps and Market Implications

Ausmon’s immediate priorities include securing land access agreements with freehold landholders and fostering community support, essential steps before expanding the drilling footprint. The company also plans to finalize financing arrangements for the broader program, signaling a commitment to advancing the project through systematic exploration phases.

Investors and industry watchers will be keenly awaiting assay results from this drilling campaign, which will provide critical insights into the grade, extent, and economic potential of the REE mineralisation. Given the strategic importance of rare earths in global technology and clean energy sectors, Ausmon’s progress in South Australia could attract heightened market attention.
