Eminence Minerals Limited (ASX:EMA) advises that it has expanded its rare earth exploration portfolio in Brazil through the lodgement of three exploration licence applications covering approximately 3,697 hectares in the Itarantim-Maiquinique district of southern Bahia.

Highlights:

- Eminence Minerals Limited has lodged three exploration licence applications covering approximately 3,697 hectares, consolidating the applications into a single project to be known as the Tayra Rare EarthProject in southern Bahia, Brazil.

- The application areas are dominated by the low-relief terrain under which deeply weathered regolith, the host of ionic adsorption clay (IAC) rare earth deposits, is preserved elsewhere in the district. Reconnaissance desktop measurement indicates that approximately 84% of the corridor (3,120 ha) lies at an interpreted gradient of 15% or less, rising to 96% within some areas. The classification addresses preservation potential only and is not a measurement of rare earth content.

- Public-domain airborne radiometric data displays elevated thorium dominance over potassium above district background across areas of the Tayra project, approaching the ratio measured over the adjoining IMC project ground. These are relative measurements on a rendered image and are not radioelement concentrations.

- The project is located in an established exploration district with access via sealed roads and grid power, together with access to a skilled regional workforce and established mining and exploration services.

- The Tayra area sits within a broader alkaline and metasomatic geological province, with mapped alkaline granitoid bodies approximately 0.8 km from the Poligono Principal and mapped fenite approximately 5 km southeast of Tayra.

- Tayra is strategically located within the Itarantim-Maiquinique rare earths district, with portions of the Tayra application areas directly adjacent to exploration tenure held by NYSE American-listedIMC Rare Earths Ltd (NYSE: IMC ~US $840M market cap) and its Itarantim Rare Earths Project.

- Protolith fertility is the principal technical risk. The ground applied for is mapped on orthogneiss, and the presence beneath it of a weatherable rareearth-bearing source rock has not been demonstrated. A structured and cost-effective work plan will be developed for the Project to address technical risks.

Cautionary Statement: The Tayra Project application areas adjoin tenure held by IMC RareEarths Ltd (NYSE:IMC). Eminence has not verified, and does not report in this announcement, any exploration information of that company. Proximity to that tenure provides a favourable regional geological framework; it is not evidence of mineralisation within the application areas and does not guarantee the discovery of mineralisation or of comparable grades. Mineralisation on adjacent or nearby properties is not necessarily indicative of mineralisation within the Tayra Project.

The three applications will be advanced collectively as the Tayra Rare Earth Project ("Tayra" or the "Project"). The applications were lodged with the ANM in the name of EQN Brazil Ltda, a wholly owned subsidiary of Eminence Minerals Limited, under process numbers 871.180/2026, 871.181/2026 and 871.183/2026. The areas were identified through a desktop review of publicly available geological, topographic and airborne geophysical datasets, and represent open ground within a district that is otherwise closelyheld. Grant of the exploration licences remains subject to the applicable regulatory processes administered by Brazil's Agencia Nacional de Mineracao (ANM).

Eminence Minerals Chief Executive Officer, Anthony Hills, commented:

"I am excited toexpand our exploration footprint further into the emerging rare earth districts of the state of Bahia, Brazil. Securing the Tayra REE Project gives Eminence a highly capital-efficient, high upside foothold in an emerging ionic clay rare earth district. Tayra places Eminence directly within the emerging Itarantim-Maiquinique rare earths district, with portions of our applications immediately adjacent to the tenure of IMC Rare Earths and its Itarantim Project. Importantly, we are entering the district at very low cost and will now apply a disciplined exploration strategy to test the geological model. Our immediate focus will be on field reconnaissance, geological mapping and targeted geochemical sampling to determine whether the favourable desktop indicators translate into prospective rare earth mineralisation. Tayra provides Eminence with a strategically located exploration platform in one of Brazil's increasingly recognised rare earth districts, while maintaining a disciplined approach to capital allocation and exploration risk."

Regional geological setting

The Tayra Project application areas lie on the southeastern margin of the Sao Francisco Craton, within the South Bahia Alkaline Province (PASEBA); a northeast-trendingbelt of Neoproterozoic anorogenic alkaline intrusions emplaced into Archaean to Palaeoproterozoic granulitic orthogneiss. The Itarantim nepheline-syenite massif anchors the southern end of the belt, and PASEBA syenites are documented as carrying a rare earth and thorium-bearing accessory assemblage including monazite, bastnasite, allanite and thorite.

Regional 1:100,000 mapping (Figure 2*) resolves the corridor into three lithostructural domains. The full extent of all three application areas is mapped as the Itapetinga Complex (A4PP2t), a Neoarchaean-Palaeoproterozoic assemblage of mylonitic garnet-bearing orthogneiss of syenogranitic to tonalitic composition. The nearest mapped alkaline-suite body, a foliated monzogranite and syenogranite stock of approximately 360 ha lies some 0.8 km southeast of the Poligono Principal, and fenite of the Itabuna Intrusive Suite is mapped approximately 5 km southeast of Tayra. Faults and fractures trend dominantly northeast-southwest, and one through-going lineament crosses the corridor.

Terrain slope across the corridor was classified from contour density on the 1:100,000 topographic compilation (Figure 4*). Approximately 3,120 ha, or 84% of the corridor, falls at an interpreted gradient of 15% or less: 1,925 ha (96%) of Gleba 1, of which 1,732 ha lies below 5%; 878 ha (82%) of Gleba 2; and 317 ha (51%) of the Poligono Principal, the last carrying 176 ha above 25% over the ridge that occupies its centre. Gleba 1 accordingly presents the closest local analogue to the plateau remnant settings beneath which regolith thickens elsewhere in the district. The classification measures preservation potential only and says nothing of tenor.

Airborne radiometrics

All three application areas return responses above district background in the equivalent thorium and equivalent uranium channels of the public-domain ternary composite (Figure 5*). Gleba 2 returns a thorium-to-potassium ratio of 1.05 against a district background of0.73, the closest of the three to the 1.15 measured over the adjoining project centre, and the third highest absolute thorium response of the domains examined.

The readings are not uniformly favourable, and the Company reports them in full. ThePoligono Principal returns the brightest total response of the corridor but is dominated by potassium, at a thorium-to-potassium ratio of 0.78 that sits at district background. A potassium-dominant response is more readily explained by felsic rock atsurface or subcrop than by mature regolith from which potassium has been leached, and it is not the signature that the district targeting sequence seeks. Gleba 1 returns the weakest absolute response of the three, so that its case rests on geomorphology rather than on radiometry.

Basis and limitations of the desktop measurements

The slope classification in Figure 4* is a contour-density proxy computed by the Competent Person on the 1:100,000 topographic compilation with a 300 m analysisradius. It is a planning proxy and not a measured slope model. The radiometric ratios quoted above are relative comparisons of rendered colour within a single stretched image; they are not concentrations of eTh, K or eU in ppm or per cent and must not be read or reproduced as such. The airborne survey was flown at 500 m line spacing, which does not resolve features at the scale of an individual application area. No field work, sampling, drilling or analysis has been undertaken on the application areas.

Magnetics. On the equivalent magnetometric compilation, a composite magnetic high of district scale occupies the ground to the south and southeast of the application areas, toward the mapped alkaline bodies and the adjoining project ground, with the mapped fenite on its northwestern shoulder. The eastern areas straddle a discrete north-northeast-trending magnetic low. No depth or susceptibility modelling has been performed, no magnetic target is reported, and the pattern is treatedas a framework observation pending located data.

Protolith fertility - the principal technical risk

The three application areas are mapped in their entirety on orthogneiss of the Itapetinga Complex. The ionic adsorption clay model requires aprotolith carrying weatherable rare earth-bearing accessory minerals; that condition has not been demonstrated beneath the application areas and cannot be demonstrated from desktop data. Protolith fertility is therefore the principal technical risk to the Project and is the first question the planned field program is designed to answer.

Established Infrastructure and Exploration Access

Tayra is located within an established exploration district with close proximity to sealed roads, gridpower and established regional services. The broader Itarantim area has supported sustained mineral exploration activity, providing access to local technical personnel, contractors and exploration services. The Project's proximity to existing infrastructure is expected to support a staged and capital efficient exploration strategy, with initial work focused on low-cost geological and geochemical programs before any consideration of more intensive exploration.

Exploration Strategy and Next steps

Following the grant of the exploration licences and completion of the necessary permitting and access arrangements, Eminence intends to undertake a staged exploration program across the Tayra Rare Earth Project. Initial activities are expected to include verification and refinement of available geological, topographic, structural and airborne geophysical datasets, followed by field reconnaissance and geological mapping across priority low-relief areas. The Company also intends to assessregolith and weathering profiles to identify areas where deep weathering may be preserved, together with targeted soil, regolith and rock-chip sampling and appropriate geochemical analysis where warranted. Results from the initial field programs willbe integrated with the regional geological and geophysical datasets to refine and prioritise exploration targets, with follow-up programs, including auger or other drilling, to be considered where supported by the results. The Company will provide further updates as exploration progresses and meaningful results become available.

Concession Application and Status

Eminence has applied for these three concessions. Under the Brazilian mineral rights system administered by the ANM, applications are ranked on a first-come, first-served (priority) basis. There is no guarantee that all three applications will be granted to Eminence. The Company advises investors that the tenure status of the Tayra Project is subject to final confirmation by the ANM.

Eminence will update the market in due course once claims grants have been officially registered.
