FY26 was not the year any of us wanted. On 1 June 2026, a wall failure at our Pearse South open pit, caused by a soft graphitic shale exacerbated by rainfall, brought open pit mining to an immediate end. The loss of an estimated $39 million in forecast revenue, which we had planned to fund the ramp-up of underground mining, forced a hard reset: 111 employees made redundant, 18 contractor positions terminated, and the processing plant placed into care and maintenance. I want to be clear. Results like these are ultimately the Board's responsibility, and mine as Chair. We responded decisively rather than compounding the setback, raising approximately $12.9 million through a placement and entitlement offer, paying every employee entitlement and creditor in full, and redirecting the Company toward an intensive drilling program to build a larger underground inventory ahead of a future production decision. It would be wrong to let a difficult year obscure real point of strength. Our Mineral Resource base grew 22% in the June quarter alone, to 12Mt, and net revenue from metal sales totalled approximately $69.7 million for the year. At year end we were debt-free, and subsequent to year end — with the $10 million deferred Misima payment and the completed entitlement offer — our unrestricted cash grew to approximately $22.7 million. The processing plant, though on care and maintenance, remains fully permitted and one of only two polymetallic plants in the Cobar region. These are the foundations we are building from. After eight years on Kingston Board, including six as the Chair, I have decided this is the right time to step down. In the current circumstances facing the Company, I believe the Board needs a fresh perspective to carry the turnaround forward, and I do not want my own tenure to be a reason that change is slower than it needs to be. The Board, supported by an external consultant, has commenced a process to identify and appoint a new Chair and Directors. I will remain in the role until a successor is appointed, to ensure a smooth transition. To my fellow non-executive directors, thank you for your candor and commitment through a demanding year. To Andrew and the executive team, thank you for your resilience. To our employees, particularly those affected by this year's difficult decisions, thank you for your professionalism. And to you, our shareholders, thank you for your patience and continued support. It has been a privilege to serve as the Chair of Kingston Resources. I am confident in the underlying asset value we have built, and I will be watching the Company's next chapter with great interest, and as a continuing shareholder myself. Yours sincerely Mick Wilkes Non-Executive Chair 11 September 2026 - 4 - Directors’ Report The Directors present their report together with the financial statements of the Consolidated Entity (or ‘Group’), being Kingston Resources Limited (‘Kingston” or the “Company’) and its subsidiaries, for the financial year ended 30 June 2026 and the independent auditor’s report thereon. PRINCIPAL ACTIVITIES The Company is an Australian-based company listed on the ASX. The principal activity of the Group during the period was mineral production and exploration. 1. OPERATING RESULTS AND REVIEW OF OPERATIONS FOR THE YEAR Operating Results Review of Operations The trajectory of mining operations changed materially in the final quarter. On 1 June 2026, a pit wall failure in the Pearse South open pit caused the immediate suspension of open pit mining. The risks and costs of regaining access to the pit outweighed the benefits of mining the remaining ore. The Company assessed a range of remediation options to continue recovering the remaining ore, but all options were unfeasible. The revenue from this ore was planned to fund the ramp up of underground mining. The Company considered accelerating the transition to underground mining, however this risked insolvency. In response, the Company made 111 personnel redundant, terminated 18 contractor positions, placed the processing plant into care and maintenance, and redirected its strategy toward an intensive underground and regional drilling program to expand the resource base ahead of a future decision to recommence underground production. All employee entitlements and creditors were paid in full. Kingston initiated a placement and entitlement offer to raise approximately $12.9 million in new equity to fund drilling, resource and reserve estimates, and plant expansion studies. While the pit wall failure is a significant setback, it does not diminish the underlying asset value: the Mineral Resource base has grown consistently and remains the foundation for Kingston's next phase of growth. The processing plant also remains a major strategic asset despite moving to care and maintenance — fully permitted and maintained in operating order, it is one of only two polymetallic processing plants in the Cobar region, positioning Kingston to benefit from future underground ore feed as well as numerous third-party ore, tolling and regional consolidation opportunities. At 30 June 2026, Kingston held $11.74 million in unrestricted cash (plus $7.47 million in restricted cash held for its Rehabilitation Security Bond), was debt-free, and had a growing Mineral Resource base. Subsequent to year end, the Company received a $10 million deferred payment from Ok Tedi Mining Limited relating to the sale of the Misima Gold Project and completed its $8.47 million Entitlement Offer, bringing unrestricted cash to approximately $22.7 million as at 31 July 2026. 2. MINERAL HILL MINE 2.1 Pearse South Pit Wall Failure On 1 June 2026, following the mining of 33kt of ore at 2.6g/t gold and 40g/t silver from Pearse South during April and May, site personnel identified tension cracks in the pit's access ramp and a wall failure in the open pit. Open pit mining was immediately suspended and all personnel and equipment were safely removed, with no injuries reported. External geotechnical experts engaged by Kingston attributed the instability to a soft graphitic shale at the base of the pit that had interacted with existing structures and been exacerbated by rainfall. The Company assessed remediation options, including a ramp redesign, but determined that the time required and the resulting sterilisation of a material amount of remaining ore made re-entry unfeasible; Kingston subsequently decided not to resume mining at Pearse South. The underground orebodies at Mineral Hill are accessed via separate portals and were not physically affected by the failure. However, Kingston had planned to fund the ramp-up of underground mining from Pearse South operating cash - 5 - flow, and the loss of this revenue — estimated at $39 million of gross revenue forecast between the June and September 2026 quarters — required a broader change in strategy. Reflecting the pit's closure, the Ore Reserve reported at 30 June 2026 no longer includes any Pearse South material (see section 3). In response, Kingston delayed the previously targeted September 2026 start of underground production in favour of an intensive drilling program — 25,000m budgeted for FY2026–27, covering resource expansion, infill drilling and near- mine exploration — together with engineering studies to determine the optimum size of the processing plant, aimed at building a larger underground mining inventory ahead of a future decision to recommence production at scale. The Pearse South ROM stockpile was fully processed by the end of June 2026, after which the plant was placed into care and maintenance to conserve capital for drilling and resource and reserve studies. To fund the transition, Kingston raised approximately $12.9 million (before costs) via a $4.4 million Placement (completed 25 June 2026) and an $8.47 million fully underwritten Entitlement Offer (completed 23 July 2026), both priced at $0.035 per share. Kingston’s largest shareholder Farjoy Pty Limited subscribed for $1.6 million under the Placement and, including its entitlement and sub-underwriting commitments, increased its shareholding to 25.09% on completion of the Offer. 2.2 Open Pit Mining and Processing Open pit mining and processing continued at Mineral Hill's Pearse North and Pearse South pits for most of the year. Commissioning and ramp-up of the processing plant's flotation circuit in the first half lifted average monthly throughput, driving a 7.5% fall in gold sales and an 11.72% increase in silver sales between the September and December 2025 quarters. Mining at Pearse North was substantially completed during the December 2025 quarter. Pearse South was affected by two geotechnical events during the year. A wall hazard identified in the December 2025 quarter required a pit redesign and haul ramp relocation, delaying access to higher-grade ore and deferring an estimated 1,000–1,200oz of gold production into the second half. Feed grades subsequently improved materially through the March 2026 quarter, reaching an average of 2.35g/t gold and 87.6g/t silver, though ore mined reduced quarter-on-quarter as the Company applied additional wall-monitoring and risk-reduction measures. Separately, carbonaceous material in Pearse South ore reduced gold recovery in the CIL, leading to overall recovery falling to 46% in the March 2026 quarter; the Company responded by redirecting all ore feed to the flotation circuit and installing additional flotation and filtration capacity to lift throughput and recovery. On 1 June 2026, a wall failure in the Pearse South open pit brought open pit mining to an end. Across the year, the Company mined 233,636t and processed 250,003t of ore from its open pits, for total gold sales of 8,504oz and silver sales of 161,278oz.

Silver grade was not separately reported for Q1 FY26. Net revenue from metal sales totaled approximately $69.7 million for the year, comprising approximately $15.8 million, $18.1 million, $24.8 million and $11.0 million in the September, December, March and June 2026 quarters respectively. All-in-sustaining costs, where disclosed, were $3,906/oz, $5,771/oz and $3,128/oz for the September, December and March quarters respectively. 2.3 Underground Mining Development Kingston made significant advances during the year in developing the Southern Ore Zone (SOZ) underground mine toward production. Key work included the implementation of an owner-operator mining strategy, building out underground workforce and fleet — including development jumbos, loaders, trucks and a production long-hole rig— and completing key infrastructure, notably a surface return air rise finalised in the March 2026 quarter. Underground development advanced steadily across the year, including a March 2026 quarter trial in which the Company trucked and batch-processed its first copper-gold ore, producing an initial copper concentrate that de-risked the eventual transition to underground and base metal production. Following the Pearse South pit wall failure in June 2026, the Company decided to delay the start of underground production — discussed further in section 2.4. An underground crew was retained at year end to continue development rehabilitation and support the ongoing drilling program. 2.4 Mineral Resource Growth and Exploration Kingston's Mineral Resource base at Mineral Hill grew substantially during the year, driven by drilling. At the start of the year, Mineral Hill's Total Mineral Resource stood at 7.8Mt @ 1.42g/t gold, 26g/t silver, 1.0% copper, 1.4% lead and 0.9% zinc. Following underground drilling at the Southern Ore Zone and Parker's Hill, Kingston released an updated Mineral Resource estimate in November 2025 that increased the Company's Total Mineral Resource by 29%, to 10Mt, with Measured and Indicated Resources comprising 60% of the total. Included in this update was the declaration of a maiden Mineral Resource at Red Terror (214kt at 1.5% copper and 1.07g/t gold). A further major upgrade to the SOZ Mineral Resource estimate was released in June 2026, incorporating an additional 26 underground drill holes for 3,413m. This increased the SOZ Mineral Resource by 50%, from 4.36Mt to 6.54Mt, with Measured and Indicated tonnage increasing 38% to 3.05Mt and Inferred tonnage increasing 62% to 3.49Mt. Across all Mineral Hill deposits, the Total Mineral Resource increased 22% during the June 2026 quarter, from 10Mt to 12Mt, containing an estimated 332koz of gold and 107kt of copper. (Figure 2) - 7 - Figure 2: Mineral Hill Resource growth since acquisition in 2022. Regional and underground exploration during the year targeted extensions and new discoveries at the Southern Ore Zone, Red Terror, Bogong and Long Panel. Surface RC drilling at Bogong (15 holes for 3,867m) and Long Panel (6 holes for 1,629m) was completed in the December 2025 quarter. Underground diamond drilling at SOZ and Red Terror intensified through the second half of the year, with 4,384m drilled between SOZ, Red Terror and Jack's Hut in the June 2026 quarter alone. Notable results included: ● Red Terror (KSNDDH080): ○ 19m @ 10.75g/t Au, 0.63% Cu, 8g/t Ag from 41.0m, including: 8.55m @ 23.80g/t Au, 0.91% Cu, 16g/t Ag from 42.5m ● Red Terror (KSNDDH081): ○ 17m @ 5.09g/t Au, 0.93% Cu from 40.0m, including 4.00m @ 8.83g/t Au and 1.40% Cu ● Southern Ore Zone (KSNDDH085): ○ 31.10m @ 2.68% Pb, 2.62% Zn, 24g/t Ag (1.96% CuEq) from 165.9m (~12m Estimated True Width, ETW). ○ 22.10m @ 1.62g/t Au, 1.47% Cu, 8.98% Pb, 3.13% Zn, 132g/t Ag (7.61% CuEq) from 209.0m (~9m ETW). Mineralisation at both Red Terror and the Southern Ore Zone remain open. Kingston has planned a further 25,000m of drilling for FY2026–27, prioritising extension opportunities at the Southern Ore Zone, Jack's Hut, Red Terror and Parker's Hill East. - 8 - Figure 3: Oblique cross-section of KSNDDH085 and KSNDDH086 at the Southern Ore Zone, illustrating the high-grade intercepts Figure 4: Red Terror drilling results, indicating potential extension of high-grade gold and copper to the south - 9 - Figure 5: KSNDDH085 drill core, 215.90m–228.75m (Trays 53–55), Southern Ore Zone, corresponding to the high-grade intercept from 209.0m. Source: ASX announcement, 7 July 2026. - 10 - 2.5 Mineral Hill Strategic Pivot Mineral Hill's long-term value has always been centred on realisation of the high-grade polymetallic underground deposits via the fully approved processing plant located in the highly prospective Cobar Basin. The Company's immediate work plan comprises: ● 25,000m of infill and extensional drilling – utilising a full-time underground diamond rig with surface diamond and RC rigs for step-out drilling focused on: ○ Southern Ore Zone (SOZ) – extensions in the G/H Lode and Upper A Lode areas. ○ SOZ Footwall - further depth and along-strike extensions. ○ Jack's Hut – down-dip and along-strike extensions. ○ Jack's Hut–Iodide Zone – southern continuation of Jack's Hut. ○ Red Terror – extensions of the high-grade gold-copper mineralisation to the north. ○ Parker's Hill East – testing a potential new target. ○ Bogong - targeting potential elevated gold and copper mineralisation in the deeper parts of the system. ● Mineral Resource updates for the Southern Ore Zone (SOZ) and Jack's Hut, to grow the underground Measured and Indicated Resources. ● Plant expansion studies to evaluate and support an expanded operation targeting 700ktpa. ● Delivery of a larger Ore Reserve to support the underground mining and processing plant restart, and to underpin the future expansion potential of Mineral Hill. The work plan is designed to grow the underground Mineral Resource and Ore Reserve base to support a larger operation with an extended mine life, and a clear pathway to increase the production rate.

BUSINESS RISKS As part of the Operating and Financial Review, the Group has identified material business risks that could impact its financial performance, position, and future prospects. These risks are actively monitored by management and the Board, with mitigation strategies in place where possible. The key business risks are outlined below: Risk Overview Mitigation Strategies Mineral Resources and Ore Reserves Risk of a material variation to Mineral Resource and Ore Reserve estimates due to technical or financial changes. Ongoing resource development and grade control drilling, Scheduling higher confidence material in the near term mine plan. Exploration risk Exploration activities may fail to identify new mineralisation or convert exploration targets into Mineral Resources, limiting future mine life extension and growth opportunities. Maintain a systematic and disciplined exploration program focused on priority targets, utilise experienced geological personnel and external consultants, apply rigorous geological modelling and data validation processes and continually review exploration outcomes to optimise capital allocation. Production and Cost Estimates Unforeseen production cost increases resulting in Kingston not realising its operational or development plans or in such plans costing more than expected or taking longer to realise than expected. Operating the business as an owner-operator, thereby having more direct control on adherence to forecasts and managing capital and operating costs. Geological and Geotechnical Unforeseen geological and geotechnical difficulties may be encountered that require additional operating or capital costs to remediate. Engage a geotechnical engineer to complete analysis and advise on all engineering designs, ground support and mine scheduling work. Permits and Approvals Risks Scheduling delays resulting from the requirement to comply with regulatory approvals. Manage regulatory risk with ongoing long-term planning and project management to ensure adequate time allowances are made. Occupational Health and Safety Adverse impact from potential workplace safety incidents Comprehensive safety management system, regular hazard/incident reporting and the employment of full-time safety officers. Land Access (Including Native Title) Delays related to land access issues arising from native title or landholder disputes. Ongoing open dialogue with all native title claimants and landholders, negotiating mutually beneficial arrangements. Cash-Flow risk The Group's cash flows may be adversely affected by fluctuations in, operational performance, capital expenditure requirements, funding availability and broader economic conditions. Insufficient cash flow may impact the Group's ability to fund operations, growth initiatives and ongoing development activities. Maintain prudent liquidity management and regular cash flow forecasting, monitor expenditure against approved budgets, preserve financial flexibility through access to capital markets, and optimise operating performance and working capital management. - 13 - 4.

SUSTAINABILITY REPORT 6.1 Governance During FY26, Kingston continued to strengthen the way sustainability matters are considered in day-to-day decision- making. The focus was on making sure environmental, social, safety and governance risks are visible, regularly discussed and understood by the people responsible for managing them. The Board and its committees continued to receive regular updates on material business risks, including matters relating to safety, environmental performance, community engagement, regulatory compliance and climate-related risk. This helped ensure that sustainability risks were considered alongside operational, financial and strategic matters. A key focus during the year was improving the practical use of Kingston’s risk management processes. This included updating the Mineral Hill broad brush risk assessment, reviewing risk registers, clarifying ownership of key controls and encouraging more regular conversations about risk at site and management level. The aim was to make risk management more useful to the business and more connected to how work is planned and carried out. Board and management site visits also provided an opportunity to test how risks and controls are working in practice. These visits supported open d
