The Project is fully funded, construction is underway and we have a clear pathway to first concentrate production targeted for June 2027. Since completion of FEED, we have continued to strengthen the Project through mine plan optimisation, improved metallurgical recoveries, infrastructure optimisation and the acquisition of the DeGrussa Process Plant, extending mine life from 8.5 years to 10.5 years while reducing capital, schedule and execution risk. The results demonstrate the value of this work, with the forward-curve pricing case delivering a pre-tax NPV₈ of approximately A$1.06 billion, a 97% IRR and approximately A$1.7 billion in life-of- mine free cash flow, with A$205 million of capital remaining to complete the Project. Importantly, these economics are supported with executed contracts and by tangible progress on the ground, with early works complete, the accommodation village operational, bulk earthworks underway, and relocation and reconstruction of the process plant commenced. Our focus is now firmly on safely delivering construction, maintaining discipline around cost and schedule, and preparing for commissioning and operations. With construction advancing and funding secured, Sorby Hills is well positioned to become a long-life Australian silver-lead operation, with further value potential through resource and reserve growth, continued optimisation and significant exposure to silver.” 1 Spot prices as at 10 September 2026 2 Forward curve Silver Price and exchange rate at 10 September 2026 and CRU lead prices at 30 June 2026 (as required by the Syndicated Facility Agreement) 3 Measured at 1 September 2026 4 Measured at 1 September 2026 Highlights • Fully funded through construction and commissioning. Over A$350 million in debt and equity funding has been secured to deliver Sorby Hills through to commercial production, providing a strong financial foundation for Project execution. • Life-of-mine Production Target extended by two years. The expanded Sorby Hills Mineral Resource Estimate supports an increased life-of-mine Production Target of 22Mt, containing 690kt of lead and 26Moz of silver, with clear opportunities for further growth through extensions to existing deposits and exploration of greenfield prospects. • Sorby Hills Ore Reserve upgraded. The updated Ore Reserve of 18.3Mt at 37.3g/t silver and 3.2% lead represents a 15% increase in contained silver and a 10% increase in contained lead, providing a stronger foundation for the expanded life-of-mine Production Target. • DeGrussa Processing Plant acquisition delivering substantial benefits. Repurposing an existing, proven processing facility has mitigated exposure to capital cost escalation and procurement bottlenecks, providing greater cost and schedule certainty. • Construction advancing on schedule. Early Works are complete, Site Accommodation Facility is operational, Bulk Earthworks are well underway, dismantling of the DeGrussa Processing Plant forecast to complete by 30 September 2026, and foundations for its reconstruction at Sorby Hills are being poured. Key infrastructure packages, including power, water reticulation and concentrate containers, are progressing in line with the development schedule. • Construction progressing on budget. Approximately A$56 million (21%) of total capital expenditure has been incurred, with the majority of the remaining A$205 million, including A$17 million in contingency, covered by fixed-price EPC contracts (e.g. Process Plant, Bulk Earthworks). This provides a high degree of cost certainty and supports delivery within the Project's capital budget. • First concentrate production scheduled for Q3 2027. • Operating cost estimates refreshed. More than 80% of budgeted operating costs have been updated using current market pricing and contractor quotations. These include mining costs based on preferred contractor rates, power costs based on the latest Horizon Power quotations, salaries benchmarked against the Hays FY26/27 Salary Guide, process reagents based on supplier quotations, and FIFO and messing costs based on contracted rates and current airfares. This provides greater confidence in forecast Project operating costs and cash flows. • Enhanced metallurgical recoveries at high-grade Norton Deposit. Additional metallurgical testwork has identified a pathway to improved recoveries from the high- grade Norton deposit, with the potential to increase lead and silver production and strengthen cash generation during the initial years of operation. • Optimised mine schedule delivering stronger early cash flows. Mine schedule optimisation brings forward higher-value production, accelerating cash generation during the early years of operation, reducing ramp-up risk, strengthening debt-servicing capacity and enhancing shareholder value. • Cost structure delivering substantial leverage to silver prices. Sorby Hills is positioned to benefit from its underlying lead production, which is expected to cover the Project's operating cost base, effectively delivering "free silver". This cost structure provides substantial exposure to silver prices, with higher silver prices translating into additional operating margins and free cash flow. • Robust Project economics. The Sorby Hills Project Delivery Plan delivers compelling Base Case economics, including a pre-tax NPV₈ of A$1.06 billion, an IRR of 97%, C1 cash costs of US$2.80/oz of payable silver and average annual EBITDA of A$184 million. 3 Cautionary Statements The Project Delivery Plan has been undertaken to assess the technical and economic feasibility of developing an open pit mine and processing facility at the Sorby Hills Lead-Silver-Zinc Project in the Kimberley Region of Western Australia. Boab holds a 100% interest in the Project through its wholly owned subsidiary, Sorby Hills Pty Ltd. The Production Target underpinning the financial forecasts comprises 53% Measured Resources, 31% Indicated Resources and 16% Inferred Resources. The Ore Reserves and Mineral Resources underpinning the Base Case Production Target have been prepared by a Competent Person in accordance with the JORC Code. There is a low level of geological confidence associated with Inferred Resources and no certainty that further exploration will result in their conversion to Indicated Resources or return the same grade and tonnage distribution. Further evaluation and appropriate studies are required to establish sufficient confidence that the Production Target will be met. The economic outcomes of the Project Delivery Plan are based on assumptions regarding commodity prices, concentrate treatment and recovery charges, exchange rates and other economic variables outside the Company’s control and subject to change, which may materially impact economic outcomes.

Location of the Sorby Hills Project within the East Kimberley Region of Western Australia Project Location and Tenure The Sorby Hills Lead-Silver-Zinc Project (“Sorby Hills”, the “Project”) is the largest undeveloped, near-surface Lead-Silver-Zinc deposit in Australia. The Project comprises granted mining leases covering six known Lead-Silver-Zinc deposits in the Kimberley Region of Western Australia, 50km northeast of Kununurra and 159km by sealed road from Wyndham Port (Figure 1). The Project comprises five granted Mining Leases: M80/285, M80/196, M80/197, M80/286 and M80/287. Boab Metals Ltd (“Boab”, the “Company”) holds a 100% interest in the Project via it’s wholly owned subsidiary Sorby Hills Pty Ltd. The Project is located within the Native Title Claim area WAD124/04 as determined on the 24/11/2006 Miriuwung Gajerrong #4 (WC04/04). As the mining tenements pre-date the Native Title Act, SMPL does not have a mandatory requirement to negotiate a formal Indigenous Land Use Agreement / Co-existence Agreement with Traditional Owners. However, consistent with Company’s social and community commitments and in the interests of developing positive working relationships with Traditional Owners, SMPL has sought to negotiate an agreement with the MG Corporation which outlines employment and contracting opportunities and other benefits that can be enabled through the Sorby Hills project to Miriuwung and Gajerrong peoples Permitting & Approvals The Project has received all primary approvals to commence construction and mining at the Project including the approval under the federal EPBC Act, and based approvals including those required under the WA EP Act Part IV and Part V and those required under the WA Mining Act including the Mining Proposal and Closure Plan. 5 Construction Progress Since completion of the FEED Study, the Sorby Hills Project has transitioned from a development- stage opportunity to an active construction project with significant progress made since a Final Investment Decision was made by the Company in December 2025..

ERM Ore Reserve Report is attached as an addendum to this announcement. Compared with the previous Ore Reserve of 15.2Mt at 3.5% Pb and 39.0g/t Ag, the 2026 Ore Reserve (Table 3) has increased to 18.3Mt at 3.2% Pb and 37.3g/t Ag, representing an increase of approximately 3.1Mt, or 20%. The Ore Reserve has been evaluated on the basis that Inferred Resources are deemed to be waste. The Ore Reserve forms a subset of the Sorby Hills Production Target.

This change was enabled through the improved water management strategies, incorporating an evaporation basin coupled with evaporators, de-risking the project. The revised schedule accelerates the production of both lead and, in particular, silver, bringing forward revenue and improving cash generation during the critical early years of operation. As a result, Project cash flows over the first five years of production have improved materially compared with the FEED Study. The first 7.5 years of the Project Delivery Plan Production Schedule is supported by 97% Measured and Indicated Resources (Figure 4). Figure 3: Sorby Hills Mining Schedule by Pit 12 Processing The core design basis and process fundamentals of the Sorby Hills Process Plant remain substantially unchanged from those presented in the Definitive Feasibility Study (DFS) and subsequent Front-End Engineering Design (FEED) study. Details relating to the repurposed DeGrussa Process Plant are provided in the documents listed in Section 10 and Appendix 11.1 - Process Plant Operations Guide (Consulting Metallurgist, Kevin Reynolds). The mine production schedule has been revised from the DFS case, replacing the initial high- grade, lower-tonnage production profile with a smoother ramp-up schedule. Plant throughput increases progressively to the full design capacity of 2.25 Mtpa by Month 6 (Figure 4), while concentrate production reaches the long-term average production range of 8,000-10,000 tonnes per month from Month 5. The Sorby Hills process flowsheet remains consistent with that established in the DFS. Following completion of the DFS, GRES completed the FEED study, advancing engineering design to approximately 25-30% completion. The FEED program included updates to the Process Flow Diagram (PFD), Process Design Criteria (PDC), Piping and Instrumentation Diagrams (P&IDs), and overall flow diagrams. The balance of detailed engineering design is being completed following the Final Investment Decision (FID), with detailed design for the repurposed DeGrussa Process Plant now nearing completion. The process plant is designed to treat 2.25 Mtpa of ore. During the first year of operations, when feed grades are forecast to be highest, throughput is intentionally moderated to a nominal 1.5 Mtpa. This strategy maintains concentrate production at approximately 110 ktpa while optimising metallurgical performance and revenue generation during the high-grade mining phase. The comminution and flotation circuits have been sized to provide sufficient operational flexibility and turndown capability to operate efficiently at these lower throughput rates before transitioning to full production capacity. Figure 4: Sorby Hills Processing Schedule by Resource Category DeGrussa Plant Acquisition and Repurposing The acquisition of the DeGrussa Process Plant from Sandfire Resources in April 2025 provides a significant development advantage for Sorby Hills. The use of an existing, proven processing facility reduces capital requirements, long-lead procurement and construction risk, while supporting a shorter pathway to commissioning and production. GRES completed a detailed technical assessment of the plant, confirming its suitability for refurbishment, relocation and integration at Sorby Hills. The repurposed plant will retain its proven crushing, grinding, flotation and concentrate handling circuits, with modifications incorporated to accommodate Sorby Hills ore characteristics, site infrastructure and operating 13 requirements. The overall process design, metallurgical basis and operating philosophy remain substantially consistent with the DFS and FEED studies. The plant is designed for a nameplate throughput of 2.25 Mtpa, with the revised production schedule providing a controlled commissioning and ramp-up profile. Throughput is forecast to reach nameplate capacity by Month 6, with concentrate production reaching approximately 8,000 to 10,000 tonnes per month from Month 5. This approach supports operational stability during start-up while providing confidence in achieving forecast production and metallurgical performance. Detailed Flow Diagrams, Process Design Criteria (PDC), Process Flow Diagrams (PFDs) and Piping and Instrumentation Diagrams (P&IDs) are provided in Appendix 10.1, with a high-level process flowsheet presented in Figure 5. A high-level process diagram is presented in Figure 5. Figure 5: Schematic flowsheet for the Sorby Hills Project Improved Norton Metallurgical Recoveries Metallurgical performance estimates for the Norton Deposit fresh ore domain have been updated based on the results of the Phase 2 Norton Flotation Optimisation Test work Program completed in August 2026. The Phase 2 program was focused exclusively on ore types previously classified as Poor Performing during the Phase 1 metallurgical test work program. Accordingly, the metallurgical recovery assumptions for Norton poor-performing material have been updated based on the Phase 2 optimisation results. No changes have been made to recovery estimates for material classified as Good or Medium performing in the Phase 1 program, nor to metallurgical assumptions for any other Sorby Hills deposits. • Phase 2 optimisation test work was undertaken on two composite samples derived from the Phase 1 poor-performing material: 14 • PPC (Poor Performing Composite), representing the overall poor-performing ore population; and • CC (Cerussite Composite), comprising a subset of the most challenging partially oxidised galena mineralisation. Test work on the CC composite remains ongoing and no CC results have been incorporated into the current estimate. This is not considered material to the metallurgical assessment, as the PPC composite was designed to be representative of the full range of Phase 1 poor-performing material. The composition of the Phase 2 composite samples is presented in Table 5: Phase 2 Composite Make-up. Table 5: Phase 2 Composite Make-up. The program demonstrated improved metallurgical recoveries for previously classified Poor Performing ore from the Norton Deposit using an optimised flotation flowsheet. Revised recovery estimates are based on locked-cycle flotation testing and have been incorporated into the overall Norton recovery estimate using a lead-metal weighted average methodology, consistent with previous DFS and FEED assessments. Recovery assumptions for other Norton ore types and all other Sorby Hills deposits remain unchanged, retaining a degree of conservatism pending further test work and improved ore-type classification (Table 6 & 7). The optimised flowsheet incorporates an additional pyrite rougher flotation stage and a concentrate regrind circuit, with opportunities to repurpose existing DeGrussa processing equipment. Implementation of these improvements will require approximately A$5 Million in additional capital expenditure (±30%), deferred until 2029 ahead of Norton ore treatment. .Table 6: Improvement in overall Norton recoveries relative to the FEED Study.

Of the total program, 1,433 m across 13 holes were drilled for metallurgical purposes, with another 1,200m across 9 holes drilled for resource/reserve expansion and exploratory objectives (Table 8). The metallurgical portion of the program was underpinned by the prospect of spatially restricting or revising upwards the recovery factors of ore from Norton and to provide additional core upon which further test work can be undertaken.
