Aruma Resources Limited (ASX: AAJ) ( Aruma or the Company ) is pleased to announce plans for

the next phase of field work to follow-up and extend the recent high-grade gallium assay results at the Saltwater Project in the Pilbara region Westen Australia.

Aruma recently reported multiple very-high grade gallium results from its most recent phase of sampling at the Saltwater Project, from the Talmine Prospect (ASX announcement 17 February 2025). A total of 16 samples graded higher than 24g/t Ga2O3 and highlight results included;

Aruma Resources managing director Grant Ferguson said:

“Aruma’s soil sampling programs at the Saltwater Project are designed to identify gold and base metals mineralisation and critical minerals across multiple structural and geophysical targets which have been identified in preparation for potential future drilling campaigns.

We are delighted with the progress achieved to date. The identification of high-grade gallium, a high valuehigh demand critical mineral, at the Talmine Prospect is highly encouraging, and our upcoming next phase of field work will seek to expand the understanding of the geological structure, lithologies and indicators of mineralisation at the Saltwater Project to vector in on targets for planned first-pass drilling, subject to results.”

The Company plans to prioritise a further infill and extension soil sampling program at the Talmine Prospect to refine the known gallium anomaly and assess the potential for additional strike extensions of the recently delineated zone of high-grade gallium mineralisation. This program, scheduled to commence in the next quarter, will involve the collection of approximately 200 soil samples over an area of approximately 1km² at the Talmine Prospect (Figure 1).

The next phase of sampling is designed to further enhance Aruma’s geological model at the Talmine Prospect and define and refine priority targets for a first-phase drilling program (subject to results). Aruma will also undertake an analysis of available high-resolution satellite and hyperspectral data and further analysis of gold and base metals pathfinder elements and bedrock geology, along with reprocessing available previous geophysical data at the Saltwater Project.

Talmine Gallium Prospect Background

The Talmine Prospect was identified from a prominent magnetic and electromagnetic anomaly extending approximately 1.2km in length.

A total of 40 soil samples were collected at the Prospect at a spacing of 50m x 400m in Aruma’s most recent sampling program. The program returned multiple anomalous very high-grade gallium assay results, and the identified zone of mineralisation which remains open to the south and northeast (ASX announcement 17 February 2025).

These results enhanced the potential of the Talmine Prospect, and a consolidation of rock chip assays from Aruma’s field work in 2023 further supports the developing geological model.

The presence of highly anomalous gallium mineralisation is known to be associated with aluminium in lateritic and bauxite deposits and sphalerite in multiple styles of base metals mineralisation,

==> picture [45 x 32] intentionally omitted <==

==> picture [156 x 53] intentionally omitted <==

associated with Aruma’s targeted base metal geological and mineralisation models at the Saltwater Project.

The Saltwater Project is situated in the Ashburton Basin, which hosts Kalamazoo Resources’ (ASX: KZR) Ashburton Gold Project (1.44Moz @ 2.8g/t Au)[1] , approximately 55km north-west from the Talmine Prospect.

Global Gallium Market

The global gallium market is dominated by China, which controls the large majority of gallium production. China recently imposed a ban on the export of gallium (as well as germanium and antimony) to the United States. This, coupled with the growing use of gallium in military applications, semi-conductors, electronics, green technologies and solar panels among other emerging technologies, has seen the demand outlook for gallium strengthen significantly – and the gallium price rise to long-term highs.

Terceira Prospect

Aruma’s latest sampling program also returned anomalous gold-arsenic results at the Terceira Prospect and delivered a first drill-ready target at this priority target area. An initial aircore drilling campaign is currently being designed, with drilling planned to commence on receipt on requisite approvals.

A gold geochemical anomaly of approximately 300m in strike length, associated with a distinct parallel magnetic anomaly has been defined at Terceira. The gold anomaly is overlain by arsenic and gallium anomalies over approximately 800m x 120m, which provides further support of the drill target.

See Figures 1 and 2 for Saltwater Project location map, showing Talmine and Terceira Prospects.
