All-In Sustaining and All-In Costs are based on copper produced. 6 Refer to ASX announcement “Major increase in Tritton Mineral Resources & Ore Reserves” dated 21 July 2026. 4 Operations Ore mined for the quarter increased by a further 57% building on strong ore delivery in prior quarter with increased tonnes delivered from Murrawombie Pit. Underground mining continued at the Budgerygar and Avoca Tank mines, with mined tonnes outperforming plan by ~10%, offsetting some of the shortfall of planned open pit tonnes. High mining rates enabled the mill to run at full capacity (1.8Mtpa rate) for the quarter, with the quarter’s throughput of 451.1kt being one of the highest quarterly mill throughputs achieved in recent years. A stockpile of 232kt of run of mine ore remained at quarter end for processing in FY27. Unscheduled downtime at the mill and crusher along with slightly lower grade and recovery from open pit ore resulted in copper production below plan for the quarter. Total copper production for the year was 23.0kt a 19% year on year improvement, however, delays in accessing Murrawombie pit ore caused by geotechnical issues near the crest of the pit in Q2 resulted in lower production. All-in sustaining costs were lower quarter on quarter due to increased copper production and inventory movements, which reflect the build-up of stockpiles at the ROM. Operating costs at Tritton were within guidance for the year. Sustaining capital was higher than guidance due to additional development at Avoca Tank required to access new reserves defined by the successful exploration program and to provide drill platforms to continue drilling at depth. Growth capital during the quarter reflected accelerated early works at the Constellation Project and increased capitalisation of Murrawombie Pit waste stripping activities following an updated accounting assessment. 5 Figure 2: Murrawombie Pit operation Constellation Project Early works commenced in May on the haul road and services corridor to the project site. Field work included:  Crushing and stockpiling of road base materials  Trenching and installation of water lines and fibre optic cable in the 29km services corridor  Road preparation and earthworks  Site office and laydown pad construction  Raw water dam construction. 6 Figure 3: Constellation haul road construction Subsequent to quarter end, the Mining Lease (ML1897) for Constellation was granted7, enabling mining activities to commence on the project site. Waste stripping in the Constellation open pit will commence in Q1 FY27. Exploration Underground exploration and resource definition drilling continued at the Avoca Tank and Budgerygar deposits during the quarter8. At Avoca Tank, drilling defined a new mineralised trend that connects with the central mineralised corridor, significantly extending the interpreted strike length of high-grade copper mineralisation while confirming continuity below the current mining levels (Figure 4). At Budgerygar, resource definition drilling continued to demonstrate thicker copper sulphide intersections than previously modelled, providing increased confidence in the geometry and continuity of the mineralised lenses. The results from both drilling programs were incorporated into updated Mineral Resource estimates completed during the quarter. Aeris subsequently released an updated Mineral Resource and Ore Reserve Estimate for the Tritton Operations9. Total Mineral Resources increased by 70% to 33Mt containing approximately 540kt of copper, while Ore Reserves increased fourfold to 10Mt containing approximately 180kt of copper. The increase reflects both the integration of the Mallee Bull and Wirlong deposits following the Peel Mining acquisition and continued organic Mineral Resource growth at Avoca Tank and Budgerygar through successful underground exploration and resource definition drilling. The expanded Mineral Resource and Ore Reserve inventory underpins the Company's strategy of developing a long-life, multi-mine copper operation centred on the Tritton processing infrastructure. 7 Refer to ASX announcement “Constellation Mining Lease Granted”, 22 July 2026 8 Refer to ASX announcement “Excellent results returned from Tritton drilling” dated 11 May 2026. 9 Refer to ASX announcement “Major increase in Tritton Mineral Resources & Ore Reserves” dated 21 July 2026. 7 Figure 4: Avoca Tank Mineral Resource comparison (Dec 2024 and June 2026) showing Mineral Resource growth from the FY26 exploration drill program. 8 Cracow Operations (QLD) Key points for quarter:  Consistent gold production 10.5koz in line with plan at AISC of A$3,812/oz  FY26 guidance met on production and costs  Exploration continued at Golden Plateau with high grade intersections reported Production Summary Unit Sep 25 Qtr Dec 25 Qtr Mar 26 Qtr Jun 26 Qtr FY26 FY26 Guidance Ore Mined kt 142.3 150.9 137.1 150.3 580.6 Mined Grade g/t 2.16 2.49 2.40 2.33 2.35 Ore Milled kt 154.3 157.3 155.3 167.1 634.0 Milled Grade g/t 1.98 2.43 2.23 2.20 2.21 Recovery % Au 90.4 90.5 90.6 88.9 90.1 Gold Produced koz 8.9 11.1 10.1 10.5 40.6 36 – 46 Gold Sold koz 8.8 11.0 10.1 10.8 40.7 Cost Summary Mining A$M 19.6 16.2 17.6 18.0 71.4 Processing A$M 7.2 7.1 7.7 7.8 29.7 Site G&A A$M 2.8 2.9 3.5 2.9 12.1 Total mine operations A$M 29.6 26.3 28.8 28.6 113.2 95 – 116 By-Product Credit A$M (0.5) (0.5) (0.7) (0.7) (2.4) Royalties A$M 2.6 3.7 3.6 3.8 13.7 Corporate G&A A$M 0.4 0.4 0.4 0.4 1.7 Inventory Movements A$M (1.9) 0.9 (1.8) 4.2 1.4 Sustaining Capital1 A$M 2.3 5.4 4.4 4.9 17.0 18 – 22 All-In Sustaining Costs2 A$M 32.5 36.1 34.7 41.2 144.5 A$/oz 3,692 3,278 3,442 3,812 3,549 Growth Capital A$M 5.5 2.1 0.6 0.1 8.3 6 – 8 Exploration A$M 1.0 0.7 3.4 2.6 7.8 5 – 7 All-In Costs2 A$M 39.0 38.9 38.8 43.9 160.6 A$/oz 4,437 3,528 3,841 4,064 3,944 1. Includes sustaining capital, capitalised mine development, rehabilitation and financing payments (principal and interest) on leased assets 2. All-In Sustaining and All-In Costs are based on gold sold Operations Cracow continued to perform well with 10.5koz gold produced on strong ore mined and milled tonnes for the quarter. Gold production for FY26 was 40.6koz, within annual guidance. All-in sustaining costs are up quarter-on-quarter on higher inventory movements related to changes in gold in circuit. Costs for FY26 were largely within guidance. Exploration costs were slightly higher than guidance as the drill program at Golden Plateau was extended on successful results. 9 Exploration Exploration drilling continued at the Golden Plateau deposit during the quarter (Figure 5), with drilling validating the updated geological model across the Main, North, East and Ferneyside lodes10. Mineralisation was consistently intersected at predicted positions, confirming the continuity of the interpreted lode system and increasing confidence in the geological interpretation. Higher-grade intersections were predominantly associated with remnant mineralisation adjacent to historical underground stoping (Figure 6), while the broader drilling program continued to define the surrounding lower-grade mineralised stockwork. Significant results reported during the quarter included:  GPS160 14.2m11 @ 9.1g/t Au (Main lode)  GPS148 2.5m2 @ 8.9g/t Au (Main lode)  GPS168 6.7m2 @ 5.2g/t Au (Main lode)  GPS171 32.2m2 @ 1.4g/t Au (Main lode)  GPS171 2.1m2 @ 4.4g/t Au (North lode)  GPS169A 18.5m2 @ 2.4g/t Au (East lode) The Golden Plateau drill program has been extended for a further 12 months. Drilling during FY27 will focus on infill drilling to increase geological confidence, in conjunction with testing strike extensions of known mineralised structures to support further Mineral Resource growth. Results from the FY26 drilling program will be incorporated into an updated Golden Plateau Mineral Resource estimate, which will support ongoing technical and economic evaluation of the deposit as a potential major ore source for the Cracow Operation. 10 Refer to ASX announcement “Significant gold intersections continue at Golden Plateau” dated 9 June 2026. 11 Estimated true thickness (m) 10 Figure 5: Plan view of modelled mineralised lodes and current drill program at Golden Plateau Figure 6: Long section view looking northeast at the Main lode, showing recent drill intersections in relation to historical stoping areas, historical drill holes and planned drill intersections. Note drill intersections are displayed as gram metre intercepts (gold grade (g/t) x estimated true width). 11 Jaguar (WA) Key points for quarter:  Operation at a low cost, essential care and maintenance  Base metals exploration program undertaken, awaiting assays Exploration Exploration at the Jaguar Project progressed during the quarter with completion of the first-pass diamond drilling program targeting base metal prospects identified along the reinterpreted volcanic corridor east of the known base metal mineralised trend (Figure 7). The eight-hole program tested each of the priority greenfield targets, comprising seven geology and gravity anomalies within underexplored prospective stratigraphy and one geology and electromagnetic target located along strike from the Jaguar deposit. Downhole electromagnetic (DHEM) surveys were completed on all drill holes following drilling. Assay results and DHEM survey data are expected during the current quarter and will be integrated into revised geological interpretations and exploration models. A comprehensive update on the drilling program will be provided once all datasets have been received and interpreted, with the results used to guide future base metal exploration activities across the Jaguar Project. Stockman Project (VIC) Key points for quarter:  Feasibility study update underway. Targeting release in H1 FY27  Project holding costs remain minimal 12 Figure 7: Jaguar base metal targets 13 Corporate Cash and Receivables At the end of the quarter, Aeris had increased useable cash and receivables of $202.3 million12 (up $52.5 million from the previous quarter) with a closing unrestricted cash balance of $164.9 million. Total restricted cash held against mine closure bonds totalled $17.7 million. An EBITDA of $285 million12 is expected for FY26, up 78% from FY25 supported by strong production, cost control and higher commodity prices.
