Estrella Resources Limited ( ASX Release: 29 October 2026 Estrella Resources Limited ABN 39 151 155 207 ASX Code: ESR Board and Management Managing Director Robert Mencel Non-Executive Directors Chris Daws Les Pereira John Kingswood Company Secretary Stephen Brockhurst Benjamin Smith Address Level 8, London House 216 St Georges Terrace Perth WA 6000 PO Box 2517 Perth WA 6831 Telephone: +61 8 9481 0389 Facsimile: +61 8 9463 6103 info@estrellaresources.com.au www.estrellaresources.com.au Estrella Resources Limited (ASX: ESR) (Estrella or the Company) is pleased to provide its quarterly activities report for the period ending 30th September 2026. The quarter coincided with a substantial escalation in the Company’s Timor-Leste exploration strategy, driven primarily by the identification of potential porphyry copper-gold mineralisation at the large-scale Laleno Dome. Commenting on activities completed during the quarter, Managing Director Robert Mencel said: “It has been a very exciting period for Estrella with the identification of high-grade copper mineralisation at the completely untested Laleno Dome in Timor-Leste. Once you see the Laleno Dome it’s hard to un-see it. It represents a large mountainous structure that is roughly 10km in diameter that is so big you can actually see it on Google Earth. You can even see some of the unique features like the rivers bending around the structure, unlike the other mountains. This gives us clues to age and formation which have helped us interpret some of our prospective exploration results. The prospective results I’m alluding to are a combination of advanced geophysics and boots-on-the- ground sampling. On the geophysics front, Estrella has been leveraging Mobile MTd which is a passive electromagnetic geophysical survey to identify sub-surface conductive anomalies. While our campaign was primarily targeted towards Ira Miri, some of the survey clipped the Laleno Dome structure which identified compelling anomalies. Whatever is present at Laleno Dome is certainly large and is definitely conductive. While we can’t know what has caused this anomaly until we drill it, one of our theories is that Laleno Dome reflects a porphyry formation. This is backed up by the sampling campaign where we’ve encountered high-grade copper and gold mineralisation at surface, with subsequent petrographic analysis determining the mineralised samples is porphyry in nature. We’re now gearing up to test this big structure with a maiden drilling campaign, reflecting the deepest hard-rock minerals exploration drilling in Timor-Leste history. This copper-gold porphyry exploration strategy at Laleno is still in its nascent stages, having been devised and executed in this quarter only. There are of course other exciting developments at the Ira Miri manganese project where a high-grade trial parcel of mineralisation is approaching a commercial sale and our understanding of the high-purity, high-grade limestone at Werumata continues to grow. Estrella has some exceptional exploration opportunities with some immediate milestones which have the potential to generate significant value for shareholders. I look forward providing further exciting updates.” Figure 1: Location of Estrella Resources’ Timor-Leste concessions TIMOR-LESTE Estrella continues to explore the virtually untested region of Timor-Leste and during the quarter, the Company announced it had been awarded two new Exploration and Evaluation licenses increasing the scope of its gold and copper prospectivity tenure1. The Autoridade Nacional dos Minerais Timor-Leste I.P. (ANM) awarded Estrella-RP the MEL2025-CA-ZE002 concession (Exploration and Evaluation Licence) which consists of 50km2 located in the south-west region of Timor-Leste. The main geological unit of economic importance within the concession is the Lolotoi Complex, which has potential to contain Orogenic Gold Deposit-style, located in the veined shear zones. The Lolotoi Complex is also known to contain igneous rocks, which may have mineralisation potential in their own right. Copper mineralisation is known to be present in rocks of the Lolotoi Complex in the Covalima Municipality. Estrella-RP has also been awarded the 50km2 MEL2025-CA-ZG001 concession (Exploration and Evaluation Licence) which is located in the Oecusse special administrative region of Timor-Leste and is prospective for gold-copper. The dominant geological unit within the concession, and the unit of economic importance is the Manamas Volcanics, young dominantly basaltic rocks that are part of the Banda Terrane and formed because of subduction. LALENO DOME COPPER-GOLD PORPHYRY PROJECT In July, Estrella announced high-grade copper, nickel, silver and manganese rock-chip assay results, reflecting the Company’s first encounter with copper-bearing mineralisation in Timor-Leste2. The discoveries at the Sica and Daudere areas were identified as part of a mapping and sampling program of the large-scale Laleno Dome. Sample locations at Sica are provided in Figure 2 and highlights included: • ESR006093 - 50.8% Cu • ESR006094 - 26.02ppm Ag • ESR006095 - 60.34% Cu and 182ppm Ag Figure 2: Location of samples ESR006093, ESR006094 and ESR006095, Sica prospect 1 See ASX Announcement dated: 16 September 2026 2 See ASX Announcement dated: 13 July 2026 Figure 3: Specimen of oxidised copper-bearing massive sulphide, sampled as ESR006095, which assayed 60.34% Cu Figure 4: The specimen displayed in Figure 3, broken in half At Daudere, Bulk samples were collected and reduced through sieving and panning, with two samples yielding anomalous results: • ESR006075: 213ppm W, and • ESR006079: 3.3ppm Ag. Although sulphides are readily visible, the assay results suggest they are entirely, or almost entirely, pyrite. Cautionary note: this anomalism is exaggerated by the pre-concentration inherent in sieving and panning. Estrella also encountered copper mineralisation outcropping approximately 300m west of the black phyllite/schist. • ESR006286: 12.4% Cu and 77ppm Ag. Quantitative X-ray Diffraction (Q-XRD) analysis was completed on the copper discoveries at Sica to understand their exact mineral composition. The Q-XRD results for ESR006095 reveal the presence of numerous arsenide minerals, including enargite and lautite, corresponding to the sample’s high arsenic content (10.7% As). These minerals are typically found in high-sulphidation epithermal deposits and porphyry copper deposits, not in Volcanogenic Massive Sulphide (VMS) copper deposits. In August, the Company announced the completion of the Mobile Magneto-Telluric drone survey (Mobile MTd)3. The survey covered the existing Ira Miri pit area within a broader 3.5km x 4.2km corridor, which also covered a small portion of the eastern part of the Laleno Dome (Figure 5) Figure 5: Location of the MTd survey, shown by an example of the resulting conductivity anomaly images The MTd survey recorded data that was processed to define anomalous areas of high conductivity. The size and intensity of the high-conductivity anomalies vary, and each anomaly also varies at depth. Also, some anomalies are only apparent at specific frequencies, while others are consistently defined at all frequencies. The best anomalies are those that are the most consistent across all data sets and these anomalies warrant investigation through drilling. Some anomalies present as zones of high conductivity that extend up to the surface from great depth, appearing like a “plume,” while others dip at low to moderate angles. The “plumes” may represent sulphide- bearing hydrothermal mineralisation, while the dipping anomalies may represent manganese-bearing beds of the Noni Formation. Drill-holes have been planned to investigate priority targets, including high-conductivity “plumes” rising from depth. Following the completion of the MTd campaign, multiple copper occurrences were observed over a 12 km section of the Laleno Dome margin, consistent with the Company's working hypothesis of a district-scale porphyry mineralising event4. 3 See ASX Announcement dated: 12 August 2026 4 See ASX Announcement dated: 26 August 2026 The five new observation sites, located on the flanks of the Laleno Dome add to the Company’s four existing locations where copper samples have already been identified. While the location of the copper samples is notable, the most significant observation is the presence of copper mineralisation within an intermediate to felsic igneous intrusive rock having porphyritic texture. This rock is hydrothermally altered, contains quartz veinlet stockworks and traces of pyrite, along with traces of malachite. Samples ESR006494, ESR006495 and ESR006498 (Figure 6) were collected from the porphyritic rock. 4 Figure 6: Example of copper mineralisation* within hydrothermally altered porphyritic rock, sampled as ESR006498. The copper mineralisation consists of malachite films on fracture surfaces and occurs as a trace through to 1-2% of the rock mass. Approximately 85m and 150m south-southeast of the porphyritic rock, copper mineralisation is present associated with the Noni Formation (ESR006494, ESR006495, ESR006496, ESR006497 and ESR006498). The proximity of this Noni Formation-hosted copper mineralisation to the porphyritic rock supports the hypothesis that the copper mineralisation in the Noni Formation may be caused by hydrothermal fluids that originated from the porphyritic rock. Figure 7: Sample ESR006497; left image shows exterior appearance, dominated by pale blue chrysocolla*, while the right image shows the chrysocolla is surface skin overlying an interior of bright green malachite, brown goethite, along with an unknown yellow-green mineral and grey silica.4 *Cautionary Statement of Visual Estimates This announcement contains references to visual results and visual estimates of mineralisation. The Company draws attention to uncertainty in reporting visual results. Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations. Note: visual samples presented in this quarterly were first reported to ASX on 26 August 2026, with assays reported on 29 September 2026 and displayed in Table 1 below. Further evidence supporting a hydrothermal origin for the copper mineralisation was observed in an area approximately 3km south of the outcropping porphyritic rock. This area was inspected as part of preparation to enable drilling to test a shallow-dipping high-conductivity anomaly that may represent a manganese-bearing bed of the Noni Formation. Approaching the interpreted location of the surface expression of the conductivity anomaly, some copper mineralisation was found in a weathered ultramafic rock, and fragments downslope from it. Samples ESR006488 – ESR006491 were collected from the ultramafic rock and material eroded from it, with samples ESR006492 and ESR006493 collected from exposed Noni Formation. Figure 8: Weathered altered ultramafic rock showing quartz stockwork and malachite* (location of sample ESR006491) NOTE: overall quantity of malachite, for the entire rock, is <1%.4 Additional support for the hypothesis of a hydrothermal origin comes from sample ESR006489, which contains a significant amount of magnetite, which is common in veins derived from magmatic hydrothermal fluids, such as the fluids emanating from “porphyry” deposits. Figure 9: Portion of sample ESR006489, comprised of malachite * (~ 5%) as films on a matrix of magnetite (10-15%), goethite (60-70%) and quartz (20-30%).4 Further north, in the area where the shallow-dipping conductivity anomaly to be tested is interpreted to reach the surface, the Noni Formation is exposed and both manganese and copper is present. Copper mineralisation occurs as small malachite nodules and as chrysocolla-rimmed concretions within the weathered bedding. Sample ESR006492 comprised of malachite nodules and chrysocolla-malachite nodules was collected from this site. Figure 10: Exposure of chrysocolla-rimmed malachite-manganese oxide* concretion aligned within bedding of highly weathered Noni Formation. Note composition of the nodule shown is ~ 5% chrysocolla, 20% malachite 50% manganese oxides and 25% clay.4 In September, Estrella received assay results for its rock chip samples which revealed exciting copper, silver and gold results in addition to petrographic analysis which identified mineralised, hydrothermally altered porphyritic diorite/microdiorite5. 5 See ASX Announcement dated: 29 September 2026 Samples collected from the northeast part of the Laleno Dome confirmed the presence of copper mineralisation within a porphyritic intermediate to felsic igneous intrusive rock (samples ESR006494, ESR006495 and ESR006498), as well as within the Noni Formation (ESR006496 and ESR006497).4 Six samples of the porphyritic rock were collected. These samples were then prepared as polished thin- sections and subjected to petrographic analysis (Figure 11). Figure 11: 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.5 Analysis of polished thin-sections 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. Approximately 1.2km north northwest of the sampled outcrop the Company found a much larger exposure of intrusive igneous rock. To enable comparison of this rock type with the mineralised porphyritic outcrop, four samples were collected to create polished thin-sections; photomicrographs display a dioritic composition and variable texture (Figures 12 and 13), ranging from fine to medium grained and variably porphyritic. The large body of rock is of similar plagioclase-rich intermediate composition to the mineralised outcrop and both contain pyrite. It is possible that both areas of outcrop are connected, representing separate surface expressions of a single intrusion. Figure 12: Photomicrograph of polished thin-section prepared from a sample collected from 267494mE/9070624mN of porphyritic diorite. 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).5 Figure 13: Photomicrograph of a polished thin-section prepared from a sample of variably porphyritic diorite collected from 267485mE/9070652mN. The image on the left is through plain transmitted light, with the image on the right transmitted light viewed through crossed polars. Most of the material is plagioclase, but biotite (Bt) is also present, along with some pyrite (Py).5 Further evidence supporting a hydrothermal origin for the copper mineralisation was observed in the area ~3km south of the outcropping dioritic rock, where samples ESR006488 – ESR006493 were collected. The weathered, hydrothermally altered ultramafic rock is fractured and contains a quartz-vein stockwork with copper mineralisation clearly associated with the quartz veinlets. 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. There is clear evidence of copper in an intrusive rock and copper-bearing veinlets in country rock peripheral to intrusive rocks, 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. 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. 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. Table 1: Cu and other elements in some samples from the Laleno Dome5 Based on the petrographic and assay results, “Porphyry style” intrusion-hosted copper mineralisation, along with hydrothermal mineralisation of rocks peripheral to the intrusive source is present at the Laleno Dome. 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. IRA MIRI MANGANESE PROJECT6 To-date, Estrella has discovered manganese mineralisation at several sites, with the Ira Miri deposit having been excavated to extract a 27,000t bulk sample proposed for sale as a market appraisal exercise. Approvals have been received to export a small manganese trial parcel overland to West Timor, Indonesia. The customer is responsible for arranging haulage7. Separately, approvals have been received to prepare the barge landing site and transport approximately 27,000-tonne Ira Miri market appraisal stockpile to the landing site. Export approval for the approximately 27,000-tonne parcel was granted on the 28th of October 2026. The execution of the sales agreement was conditional on receipt of export approval, which has now been received. The Company will update the market once binding sales terms are executed. The Ira Miri Open Pit remains open at depth and along strike. However, it is the Company’s intention to discover and develop additional manganese prospects that can produce similar, high quality manganese ore. During the period, Estrella discovered a manganiferous bed of the Noni Formation at the Leuro prospect within an eroded bank of a stream at several locations, suggesting a laterally continuous orientation8. Given the high grades (up to 57.8% Mn and an average of 34.6% Mn) and potential strike length of the mineralisation, Leuro is a significant target for further investigation by ground geophysics. At Sica, completion of traverses across the area led to recognition of a highly eroded primary source, sampled as ESR006086, which assayed 55.6% Mn. Away from this point manganese occurs at several locations, potentially derived from one or two laterally extensive manganiferous beds. 6 See ASX Announcement dated: 11 May 2026 7 See ASX Announcement dated: 13 October 2026 8 See ASX Announcement dated: 2 July 2026 B.No SampleID Easting Northing Sampledescription Auppm Agppm Asppm(%) Bappm Bippm Cdppm Coppm Cuppm(%) Hgppb Moppm Nippm Pbppm Sbppm Seppm Teppm Znppm Fe% Mnppm (%) TL-23 ESR006093 265725 9069502 malnodules(NoniFm) 0.03 3.3 3.97 7005 5.1 2 309 50.85 635 <5 3681 108 16 <5 48 40 0.21 1168 TL-29 ESR006492 269479 9067202 malnodules(NoniFm) 1.3 22.6 3955 217 33 23.9 <1 45.61 4915 <2 7 12 <5 <5 22 35 0.17 861 TL-29 ESR006496 268179 9069657 malnodules(NoniFm) NA 29.1 3.46 211 38 198 9 59.94 2887 <2 13 11 <5 <5 17 10 0.13 297 TL-29 ESR006497 268134 9069602 ccl-mal-gtnodules(NoniFm) 0.08 78 6.99 108 24 355 4 58.49 348 <2 307 <5 15 <5 13 <5 0.03 18 TL-26 ESR006286 260723 9065539 mal &azfilms/nodules(NoniFm) <0.05 77 11 12 6 <0.5 3 12.4 NA 7 7 1331 <5 5 <5 8 0.91 154 TL-23 ESR006094 265730 9069497 Mnoxgossan(NoniFm) <0.01 26.2 65 3487 3.6 1.2 113 159 17 8 50 76 4 119 <5 68 3.13 44.63 TL-29 ESR006493 269485 9067205 Mnoxgossan(NoniFm) <0.05 19.2 11 103 13 1.3 36 201 13 <2 14 32 5 109 10 63 7.87 41.68 TL-23 ESR006095 265684 9069398 oxdmassivesulph(source???) <0.01 182 10.73 4811 3.2 <0.5 6.6 60.34 2653 <5 7530 6 7 5 <5 <10 0.18 2043 TL-29 ESR006488 269324 9066896 mal nodules(UMsource?) 0.5 66 16 28 <2 <0.5 50 30.55 76 25 18 38 <5 228 30 194 25.02 466 TL-29 ESR006489 269333 9066876 mal-magrock(UMsource?) <0.05 37.9 2 <10 5 <0.5 219 23.44 37 153 9 16 <5 120 40 117 38.09 437 TL-29 ESR006490 269330 9066891 ox.Fe-cht/UM;filmsmal 1.09 70 46 22 6 0.5 137 5.4 342 28 70 81 <5 163 13 259 11.34 407 TL-29 ESR006491 269320 9066913 mal veinlets(weath'dUM?) 0.08 3.6 10 10 27 <0.5 19 33.22 22 3 25 21 <5 8 15 181 8.25 722 TL-29 ESR006494 268209 9069732 w'edalt.sulph.Porph.Withmal 0.07 1.8 <2 30 <2 <0.5 12 6561 <5 3 38 <5 <5 <5 5 34 2.26 868 TL-29 ESR006495 268210 9069733 w'edalt.sulph.Porph.Withmal <0.05 <0.5 <2 24 <2 <0.5 13 490 <5 4 40 <5 <5 <5 6 61 3.72 945 TL-29 ESR006498 268206 9069736 w'edalt.sulph.Porph.Withmal 0.17 1.4 47 15 <2 0.6 14 5334 5 <2 23 8 <5 <5 7 169 3.48 988 Following these discoveries, an initial inspection of the Daudere area, approximately 5km south-west of Sica, the Company traversed a slope strewn with numerous boulders of manganese oxides.
