Ausmon Resources Unveils Strong Rare Earths and Base Metals Assays in SA and NSW
Ausmon Resources reports promising assay results from recent drilling programs targeting rare earth elements in South Australia and base metals near Broken Hill, NSW, setting the stage for expanded exploration.
- Completed 57 aircore drill holes in South Australia's Limestone Coast with significant TREO grades
- Encouraging zinc, manganese, and gallium assays from RC drilling at Enmore near Broken Hill
- Exploration programs impacted by equipment issues and heavy rains but progressing with community engagement plans
- Quarterly exploration expenditure of $134,000 with $1.6 million loan facility in place
- Future drilling planned to test identified anomalies and expand resource definition
Exploration Advances in South Australia
Ausmon Resources Limited has recently completed a significant phase of aircore drilling across its four tenements in the Limestone Coast region of South Australia, targeting rare earth elements (REEs) within the Loxton/Parilla Sands. The 57 holes drilled in May 2025, averaging 18 meters depth, yielded notable assay results with total rare earth oxides (TREO) reaching up to 2,192 ppm in some intervals. These results build on previous drilling campaigns and reinforce the prospectivity of the Murray Basin area, where Australian Rare Earths has already established a substantial resource.
Despite a software malfunction affecting pXRF data collection on site, Ausmon successfully reprocessed samples in the lab, confirming elevated TREO values across multiple drill holes. The company has delineated three target areas for more focused drilling, signaling a transition from broad reconnaissance to detailed resource definition. Future programs will involve community consultations and access agreements to expand drilling beyond road verges onto freehold land.
Base Metals Potential Near Broken Hill
In New South Wales, Ausmon’s exploration near Broken Hill has delivered encouraging results from reverse circulation drilling at the Enmore tenement. Elevated zinc concentrations averaging 538 ppm and peaking at 1,168 ppm were intersected, alongside significant manganese and lead values. Of particular interest is the detection of gallium, a critical metal for advanced technologies, averaging 26 ppm in the upper 68 meters of the hole. This aligns with the region’s known mineralization styles and suggests potential for a polymetallic deposit.
Following these findings, Ausmon plans to resume drilling with a combination of RC pre-collars and diamond tails to better test geophysical anomalies identified in prior surveys. Additional soil sampling and exploration work are also slated to refine targets within the broader Broken Hill licence portfolio.
Queensland and Other Projects
Exploration at the Turkey Hill project in Queensland faced challenges due to heavy rains limiting access and affecting data quality. Initial sampling was conducted, but further work will require improved conditions and additional field programs. Meanwhile, gold exploration tenements near Tumut, NSW, remain on hold as the company prioritizes its REE and base metals efforts.
Financial and Operational Outlook
During the June quarter, Ausmon expended approximately $134,000 on exploration activities, focusing on drilling, geology, and project management. The company maintains a $1.6 million unsecured loan facility from Fort Capital Pty Ltd, with $660,000 currently unused, providing a runway of just over two quarters at current spending levels. No production or development activities were reported, consistent with the company’s exploration stage status.
Payments to related parties, including directors’ fees and management charges, totaled $110,000 for the quarter. Ausmon’s management emphasizes ongoing community engagement and environmental compliance as it advances its drilling programs.
Overall, Ausmon Resources is steadily advancing its portfolio of critical mineral projects with promising assay results that warrant further investment and exploration. The company’s focus on rare earths and base metals aligns well with global demand trends for technology metals, positioning it as a junior explorer to watch.
Bottom Line?
Ausmon’s latest assays underscore growing potential in critical minerals, but upcoming drilling and funding will be key to unlocking value.
Questions in the middle?
- Will Ausmon secure land access agreements to expand drilling beyond road verges in South Australia?
- How will the company address the technical challenges encountered with pXRF data collection?
- What are the timelines and funding plans for the next phase of drilling at Broken Hill and Turkey Hill?
