We have now identified copper mineralisation in porphyritic rock at Laleno Dome, which supports further testing of our geological model for a potential porphyry copper system along the Dome margin. Just as significantly, the rock-chip gold assay results are highly encouraging. Porphyry copper-gold systems are among the most sought-after targets in global exploration, and seeing both metals emerge together at Laleno Dome is exactly what we hoped the program would deliver. We look forward to advancing this work and keeping shareholders updated as further results come to hand” Laleno Dome – a growing copper-gold exploration system Estrella Resources Limited (ASX: ESR) is pleased to advise that site inspections of areas selected for drilling to test some of the high-conductivity anomalies detected by the Mobile Magneto-Telluric drone survey (Mobile MTd) resulted in copper (Cu) mineralisation being observed at five sites located on the flanks of the Laleno Dome, adding to the four sites known previously. In addition to the assays confirming copper mineralisation, gold (Au) up to 1.3ppm Au has been detected in some samples. The absence of Au in previously assayed batches of samples may reflect mineralisation zonation, and if this is true, continued sampling across the Laleno Dome may identify additional occurrences of Au, in association with silver (Ag) and Cu. A total of 11 samples were collected from the five new sites, with sample locations and details provided as Appendix 1. The nine currently known occurrences of copper mineralisation at the Laleno Dome are located around the northern part of the dome (Figures 1 and 2) and further work may identify additional sites around other parts of the dome.

Refer to Appendix 2 for results, which include trace elements to enable potential characterisation of mineralisation types. Figure 3: Cluster of 3 sample locations at the porphyritic rock, and 2 separate occurrences of mineralisation in the Noni Formation The occurrence of copper mineralisation within the hydrothermally altered porphyritic igneous intrusive rock is suggestive of “porphyry copper” mineralisation, so, to confirm the mineralogical and textural nature of the rock and thus confirm the classification and identification of the rock, 6 samples of the Office Address London House, Level 8, 216 St Georges Terrace, PERTH WA 6000 Postal Address GPO Box 2517, PERTH WA 6831 Phone +61 8 9481 0389 Fax +61 8 9463 6103 Email info@estrellaresources.com.au porphyritic rock were collected. These samples were then prepared as polished thin-sections and subjected to petrographic analysis, e.g., Figure 4. Figure 4: On the left, sample ESR006498, assaying 5334ppm (0.53%) Cu and 1.4ppm Ag, confirming copper-silver mineralisation in hydrothermally altered porphyritic microdiorite. The central image is a photomicrograph of a petrology sample of the hydrothermally altered porphyritic rock, displaying the porphyritic texture (Hb = hornblende, SPg = sericitized plagioclase, Py = pyrite) defined by plagioclase phenocrysts. The image on the right of another petrology sample shows a quartz (Qtz) veinlet, with adjacent pale alteration selvage, in an altered fine- grained matrix that contains pyrite (Py) and an unidentified carbonate mineral (Car), with prominent silica flooding emanating from the quartz veinlet present in the right side of the image. The petrology samples were not assayed. Analysis of polished thin-sections (e.g., as shown above in Figure 4) prepared from 6 samples collected from the mineralised porphyritic rock has confirmed: • the texture of the rock is consistent with a sub-volcanic intrusive rock • the rock has an intermediate composition, containing abundant plagioclase feldspar, along with small amounts of hornblende and traces of biotite and quartz. • the rock is hydrothermally altered with chlorite-sericite replacement of plagioclase and amphiboles (hornblende), along with silica flooding, carbonate replacement and presence of pyrite. In summary, the mineralised rock is a sub-volcanic variably porphyritic diorite to microdiorite, affected by chlorite-sericite hydrothermal alteration including quartz-carbonate veinlets and localised silica flooding, with patchy disseminated pyrite. This supports Estrella’s interpretation that intrusion-related “porphyry copper” mineralisation may be present in the Laleno Dome area. Additional intrusive outcrops The discovery of the outcrop of altered porphyritic microdiorite that yielded the 3 assayed samples (i.e., ESR006494, ESR006495 and ESR006498) occurred through investigation of a high-conductivity anomaly defined by the MTd survey, with a ground Res/IP (Resistivity/Induced Polarisation) survey line passing next to the outcrop. Although the outcrop of the mineralised porphyritic microdiorite is small, with the intrusive body mostly obscured by weathered Noni Formation and vegetation, the extent of the high-conductivity anomaly may indicate that the intrusion extends beneath cover.

To enable comparison of this rock type with the mineralised porphyritic outcrop, 4 samples were collected to create polished thin-sections; photomicrographs display a dioritic composition and variable texture (Figures 5 and 6), ranging from fine to medium grained and variably porphyritic.

The image on the left is plain transmitted light, with the image on the right transmitted light viewed through crossed polars. Most of the material is plagioclase, including the large trapezoidal body. The plain brown material is biotite with the other brown material mostly amphibole (hornblende).

It is possible that both areas of outcrop are connected, representing separate surface expressions of a single intrusion. The imminent regional airborne combined Magneto Telluric and Magnetic survey will pass over the ground containing this outcrop and the results are anticipated to assist determination of the sub-surface extent of the intrusion. Answering the question “have the copper occurrences all formed from the common source?” a) Evidence for an intrusion-related interpretation One interpretation is that the copper mineralisation within the Noni Formation, and in other rocks, is caused by hydrothermal fluids that originated from the porphyritic dioritic rock, with hydrothermal fluids emanating from the source intrusion infiltrating surrounding rocks, i.e., Noni Formation or other rock units. The proximity of samples ESR006496 and ESR006497 (Cu in Noni Formation) to the porphyritic rock supports this hypothesis. Further evidence supporting a hydrothermal origin for the copper mineralisation was observed in an area approximately 3km south of the outcropping dioritic rock, where 6 samples (ESR006488 – ESR006493) were collected (Figure 7).

These veinlets in some cases contain traces of magnetite and can be classified as “G-veins”, consistent with a hydrothermal origin for the copper mineralisation and typical of hydrothermal mineralisation emanating from a “porphyry copper” intrusion.

The right image shows a portion of sample ESR006491, which assayed 33.22% Cu. This selected rock-chip specimen is not representative of the grade of the broader outcrop. Note: the assay result is higher than the photo of the sample suggests; although malachite is evident as the selvage of a quartz veinlet, some of the “goethite” comprising the bulk of the sample is either enriched in Cu (Fe oxide scavenging of Cu in the regolith) or contains Cu oxides. There is clear evidence of copper in an intrusive rock and copper-bearing veinlets in country rock peripheral to intrusive rocks, as shown above in Figure 8, but the mineralisation in the Noni Formation is not associated with obvious veining. However, hydrothermal impregnation of favourable beds of the Noni Formation, or along bedding planes, is a realistic potential explanation for the presence of copper mineralisation within the Noni Formation but further work is required to test this interpretation. b) Evidence of differing styles and origins of Cu mineralisation A hydrothermal impregnation of favourable beds or bedding planes of the Noni Formation is a reasonable explanation for the presence of copper mineralisation within the Noni Formation, however, an alternative explanation is that the mineralisation is an example of a variety of “sedimentary copper” type of mineralisation, quite distinct from the intrusion-related “porphyry” copper identified in the porphyritic dioritic rocks. To attempt to identify similarities or differences between mineralisation sites, perhaps indicative of different mineralisation styles, sampling and assay-suite selection have been designed to reveal compositional differences. Selection of mineralisation specimens was intended to enable detection of a broad range of “indicator” elements, potentially allowing characterisation of mineralisation and identification of separate types of mineralisation. Estrella has previously announced results of copper mineralisation from samples despatched as batches TL-23* and TL-26* and the results from those samples have been combined with the results of the 11 samples of batch TL-29 that are the subject of this announcement, presented in Table 1. * Results announced in “High-Grade Copper, Manganese, Nickel and Silver Discoveries” (13/07/2026) Within Table 1, samples have been grouped according to the host-rock association of the sample so that patterns of elemental enrichment that may be present can be recognised and some compositional differences are recognisable.

Note that the original host-rock of sample ESR006095 is unknown (highlighted pale blue) but the pattern of anomalous elements is like samples collected from the Noni Formation, suggesting it probably was originally a component of copper mineralisation from within the Noni Formation. Secondly, the samples associated with weathered altered ultramafic rock, e.g., Figure 8, and highlighted pale purple in Table 1, all contain highly elevated selenium (Se), along with elevated cobalt (Co), molybdenum (Mo), tellurium (Te) and zinc (Zn). It is apparent that neither of these groups match closely with the assay results from the porphyritic diorite (pale grey in Table 1), which may reflect different mineralisation styles, zonation or weathering. c) Are the compositional differences a reliable guide? In fact, it is possible there is both “sedimentary copper” and “porphyry copper” (and associated epithermal vein-style mineralisation) types of copper mineralisation present in the region and Timor- Leste in general but the compositional differences supporting this are based upon assay results of only 15 samples. The interpretation of the significance of compositional anomaly patterns requires 2 important factors to be considered: Firstly, the samples (batches TL-23, TL-26 and TL-29) are from separate localities and differences in composition may reflect mineralisation zonation, present in all base-metal (including copper) deposits, rather than different mineralising causes or events. Secondly, all the samples are derived from weathered material and the type of intense chemical weathering evident in the region is well-known to result in redistribution of elements, evident as zones of leaching and zones of enrichment. The solubility, stability in solution and optimum setting for deposition and consequent enrichment of elements differ considerably. In addition, it must be considered that the differences possibly reflect initial differences in zonation of metals, overprinted by differential re-distribution of elements through weathering processes.

The origin of the copper mineralisation in the Noni Formation is debatable, and potential explanations include a “sedimentary copper” genesis however, the evident widespread hydrothermal activity adds support for a hydrothermal origin. Estrella’s current exploration concept of the copper mineralisation is that in the late Miocene Epoch, in the waning stages of the main “collisional” event that shaped Timor Leste, there was a period of magmatic activity coinciding with deformation and regional metamorphism and this resulted in intrusion of diorite which led to magmatic-hydrothermal processes. These magmatic-hydrothermal processes created “porphyry” mineralisation in the intrusions themselves (e.g., samples ESR006494, ESR006495 and ESR006498; Figure 4), along with the mineralisation presenting as “G-veins” in ultramafic rock, evident in sample ESR006491(Figure 8). The copper mineralisation present in the Noni Formation may have formed from these hydrothermal fluids also but there is some possibility that it is an example of “sedimentary copper” mineralisation. Next Steps Fieldwork, including Ground geophysics surveys (Resistivity/Induced Polarisation [“Res/IP” or “IP”]) have generated additional drilling targets and consequently additional access and site preparation tasks, some of which required additional community consultation. The company is currently awaiting Timorese Government approval to commence drilling. Commencement of the regional helicopter magneto telluric (MT) survey, extending over Estrella’s entire tenure, has been delayed by logistical factors and is now scheduled to commence in October, yielding results before the end of the year and anticipated to identify further substantial drill-targets. Equipment mobilisation is underway. In addition, planning for drilling of the high-grade limestone in the Sagadate region is advancing and, after approvals have been attained, a 4,000m combined RC and diamond (core) drilling programme is planned, subject to operational progress. This potential high-grade limestone is intended to supplement the established Mineral Resource defined for the Werumata Limestone Deposit, increasing the quantity and range of limestone products able to be produced. Ira Miri Manganese Bulk Sample Estrella continues to advance shipment preparation and export approval processes for the Category B market appraisal stockpile. The Company has completed the customer selection process for its maiden manganese trial parcel and has identified preferred customers. Export approval documentation has been lodged with the Government of Timor-Leste. Execution of the sales agreement is conditional on receipt of that approval. The Company will update the market once approval is granted and binding terms are executed. This announcement has been approved by The Board for release to the ASX.
