Highlights

• ActivEX has completed an initial phase of grid-based soil sampling at the Aramac Project in Central Queensland, comprising 99 soil samples and seven rock samples across an 8km exploration trend.

• Laboratory results identified significant soil geochemistry levels for manganese, barium, cobalt, zinc, and iron, with several elevated readings concentrated around the Dunns Road Prospect.

• Mineralogical analysis of a Goethitic Gossan rock sample identified rare earth element-bearing crandallite group phosphates, representing an early indication of REE mineralisation potential at the project.

• The initial program covered only 8km of a broader 55km geological trend, with further geochemical sampling, geological mapping, geophysical surveys, and potential drilling now in the planning phase.

ActivEX Limited (ASX:AIV), an ASX-listed gold and critical minerals explorer, has reported encouraging laboratory assay results from its latest exploration program at the Aramac Project in Central Queensland. The program, focused on grid-based soil sampling across an 8km trend adjacent to the Dunns Road Prospect, has returned geochemical results supporting the project's critical and base metal prospectivity, while separate mineralogical analysis has provided early indications of rare earth element mineralisation potential.

Soil and Rock Geochemistry Results

A total of 99 soil samples and seven rock samples were collected along the base of a North-South scarp within Exploration Permit for Minerals 28644 (the Fortuna Tenement) and submitted for multi-element geochemical analysis. The sampling was designed on a 250 metre North-South and 200 metre East-West grid, targeting the area around the Dunns Road Prospect where earlier portable X-ray fluorescence analysis had identified elevated geochemistry associated with a Goethitic Gossan.

Laboratory results returned significant soil geochemical readings, including manganese levels of 800-1,500 parts per million across portions of the grid, barium of 400-1,930 parts per million, cobalt of 25-48 parts per million, zinc of 150-313 parts per million, and iron content of 7-9%. Rock sample results also showed comparable ranges for these elements, with the highest readings concentrated near the Dunns Road Prospect. Additional Goethitic Gossan outcrops were identified along the 8km trend during fieldwork, extending the known extent of this geological feature.

Rare Earth Element Indicators — TIMA Analysis

Complementing the geochemical results, ActivEX commissioned mineralogical analysis of a Goethitic Gossan rock sample from the Dunns Road Prospect using a TESCAN Integrated Mineral Analyser (TIMA). This scanning electron microscopy-based system enables automated analysis of mineral composition and texture. The analysis identified rare earth element-bearing crandallite group phosphates, comprising approximately 0.015 weight percent of the analysed sample with 835 grains identified across fine and very fine grain sizes.

Additional REE-bearing phases identified included monazite/rhabdophane and xenotime in trace quantities. The company noted that these phases are very fine-grained and that ultrafine grains below the TIMA resolution may be underestimated, suggesting that the actual concentration of REE-bearing minerals could be somewhat higher than measured. The REE phosphates were found to be predominantly hosted by goethite. While the company describes these findings as an early indication of REE mineralisation potential, the results provide an additional avenue for further investigation as exploration continues.

Exploration Potential and Planned Next Steps

A key observation from the initial program is that it has covered only approximately 8km of a broader 55km geological trend within ActivEX's exploration permits at Aramac. The company considers the substantial remaining coverage a meaningful opportunity to further assess both the critical metal and rare earth potential of the project. The results to date have been sufficient to support planning for the next phase of work, which will include further surficial geochemical exploration along the base of the 55km scarp, targeted geological and regolith mapping and rock sampling, a drone magnetic survey along the scarp targeting the Goethitic Gossan trend, and aircore drilling of the critical metal geochemical soil trend.

Managing Director Mark Derriman noted that the correlation between elevated geochemistry and the Goethitic Gossan geological feature along the surveyed trend provides valuable information on the distribution of critical and base metals, and that the identification of rare earth-bearing minerals through mineralogical analysis adds a further dimension to the project's prospectivity assessment.

Key Insights

ActivEX's Aramac Project has moved from an early-stage discovery to a multi-commodity exploration target with documented geochemical anomalism across critical metals and early-stage rare earth indicators. The combination of soil geochemistry, rock sampling, and TIMA mineralogical analysis provides a multi-technique evidence base for ongoing exploration Investment in the project.

The scale of the unexplored geological trend — approximately 47km of the 55km total remains to be tested at the resolution of the initial survey — represents a significant opportunity for further discovery. The planned progression from surface sampling and mapping toward geophysical surveying and eventually drilling reflects a methodical approach to target refinement that is appropriate for the project's current stage.
