Financial Performance · Raised a total of £2.1 million in equity funding for the Company's DRC operations during 2025 · Cash at bank 31 Dec 2025 £1.42 million (2024: £4.33 million Operational Highlights · Conducted extensive drilling operations at the Company's Bisie North Project · Issued an inaugural Mineral Resource Estimate for the Bisie North Project Post-reporting Period Events · Raised approximately £1.6 million in equity funding in the first half of 2026 · Executed non-binding term sheets to potentially acquire further interests in the existing Bisie North licences · Completion of a further 3,250m drilling programme at the Bisie North Project · Broader Kalayi intercepts from 2026 drilling has verified geological model · Commencement of an airborne geophysical survey to assess scale · Signed option agreement over a Canadian tin-tungsten-molybdenum-indium play · Appointed Stephane Irung and Edward Loye as Non-executive Directors Paul Barrett, Chief Executive Officer of Rome Resources, commented: "The successes of the operations in the DRC during 2025 and into 2026 were marred by the untimely passing of Mark Gasson, co-founder and COO. His guidance and enthusiasm were critical to getting the Company to where it is today, with a Maiden Mineral Resource on the Bisie North Project and the potential for further upside to this following another drilling campaign that focussed on the Kalayi tin deposit. The Maiden Mineral Resource Estimate laid down a marker for the Company - strong tin grades from surface in Kalayi and significant copper, zinc and silver alongside tin in Mont Agoma form a basis for resource growth going forward. Exploration operations have continued into 2026 with further drilling and an airborne geophysical survey, the latter designed to identify additional mineral exploration targets along the tin trend and closer to the granite contact. Work started on a small-scale mining operation at Kalayi, which will produce tin from near-surface workings that will provide information for the conversion to a full exploitation licence and valuable technical information about the deposit. The Company is pursuing a new tin play in Eastern Canada, having entered into an option arrangement over several claims in the Devonian tin-tungsten-indium play of SW New Brunswick, adjacent to the historical Mount Pleasant tungsten mine. Fieldwork is planned in summer 2026 ahead of a possible drill programme in 2027. New Brunswick is a resource-friendly jurisdiction with exceptional mineral potential, and we look forward to advancing this early-stage project (subject to exercising the option). By the end of the current reporting period, the Company should be in a strong position having added value to its projects in both the DRC and Canada and we look forward to keeping shareholders appraised of our progress." Posting of Annual Report and Accounts The Group also announces that it will today be posting to its shareholders the annual report and accounts. A copy of this announcement and the Company's report & accounts will shortly be available on the Company's website.

Chairman's Statement For the Period Ended 31st December 2025 ("FY2025") Highlights for FY2025 • Conducted extensive drilling operations at the Company's Bisie North Project • Issued an inaugural Mineral Resource Estimate for the Bisie North Project • Raised a total of £2.1 million in equity funding for the Company's DRC operations during 2025 • Cash at bank 31 Dec 2025 £1.418 million (2024: £4.485 million) Post-Balance Sheet Events • Raised approximately £1.6 million in equity funding in the first half of 2026 • Executed non-binding term sheets to potentially acquire further interests in the existing Bisie North licences • Completion of a further 3,250m drilling programme at the Bisie North Project • Broader Kalayi intercepts from 2026 drilling has verified geological model • Commencement of an airborne geophysical survey to assess scale • Signed option agreement over a Canadian tin-tungsten-molybdenum-indium play • Appointed Stephane Irung and Edward Loye as Non-executive Directors Chairman's Statement I am delighted to present Rome's 2025 report, completing almost a year of intense exploration activity and culminating in the publication of a maiden Mineral Resource Estimate ('MRE') for the Company's flagship project, Bisie North, situated in a remote part of the Democratic Republic of Congo (the "DRC"). Bisie North lies in the world's highest grade tin producing fairways and is only 8km along strike from a mine producing approximately 7% of the world's tin which is reported to currently generates monthly revenues of around $80 million. Replication of this success is the Board's key objective. The last 12 months have therefore been focussed on the execution of a tin exploration drilling programme on Rome's existing licences. 2025 saw the tragic death of Mark Gasson, co-founder and COO of Rome, following a short illness. His guidance and knowledge was pivotal to the project and his experience of the regional tin play was critical in identifying the Bisie North project as having great potential, subsequently borne out in the drilling results. His enthusiasm for the exploration game is sorely missed. FY2025 saw the continuation of the drilling activity initiated in 2024 on the Kalayi and Mont Agoma deposits in the Bisie North Project, situated in the DRC, that culminated in the publication of a maiden Mineral Resource Estimate in October 2025. Almost 10,000m of core drilling had taken place following on from Rome's successful admission to trading on AIM in July 2024 and subsequent secondary fundraises. This drilling has now matured the previously identified Kalayi and Mont Agoma tin and polymetallic discoveries with an initial MRE confirming 11kt contained tin in the shallow drilled portion of the deposits, along with 45kt of contained copper, 86kt of zinc and 1.5Moz silver. Current focus is to quantify the undrilled potential in Kalayi which, because of its simple tin-based mineralogy, potentially presents a faster monetisation route for Rome shareholders. Additionally, however, metallurgical studies on the Mont Agoma polymetallic system have shown highly encouraging results in terms of recoverability to support taking this project forward. It has been another pivotal year for the Company, building out the resources at Bisie North and creating a platform for value growth in an exciting commodity space. Tin and copper are both on track for strong long-term price growth and in parallel the DRC is becoming a mainstream destination for resource investment, as discussed below. In addition to the DRC, Rome has entered into an option agreement to acquire working interests in early-stage exploration licences in the Canadian province of New Brunswick (the "Option Agreement"), in an extremely promising tin-tungsten- indium play, centred around a Devonian age tin and tungsten endowed granite system containing the historical Mount Pleasant tungsten mine. This is an early-stage project which will concentrate on field-based sampling during 2026 to develop a focussed exploration model for the area. Board Changes During the reporting period, there were several changes at Board level: Marc Mathenz and Edouard Etienvre stepped down in late 2025 whilst Stephane Irung, a DRC-based entrepreneur, was appointed as a non-executive director in April 2026. Ed Loye, an experienced resource geologist, was announced as a proposed non-executive director of Rome, in April 2026. As of the date of this report, the Board is as follows: Klaus Eckhof (Non-Executive Chairman) Paul Barrett (Chief Executive Officer) Stephane Irung (Non-Executive Director) - appointed 17 April 2026 Edward Loye (Non-Executive Director) - appointed 10 June 2026 Philip Knowles' Chief Financial Officer role is a non-board position. Outlook The Board anticipates that the updated Mineral Resource Estimate will be completed mid-2026, following receipt of the assays from the 2025/2026 drill campaign that completed in April 2026. It is expected that this update, which will focus on Kalayi, will provide confirmation of the wider intercepts that have been encountered in this programme and quantify their effect on the resource numbers. In addition, the Company is participating in an airborne geophysical survey around the northern margin of the Bisie tin granite, including the whole of the Company's licence area. It is anticipated this survey will identify drilling extensions and further exploration targets in and around Kalayi and Mont Agoma for future campaigns. The Board is very appreciative of the continued support of existing shareholders, as demonstrated in their support in funding the Company's drilling campaigns. It is the Board's intention to maximise the value of Kalayi and Mont Agoma with the drill bit and create an opportunity to generate significant returns for shareholders. Klaus Eckhof Chairman 24 June 2026 CEO's Report For the Period Ended 31st December 2025 During the year ended 31 December 2025, some 3,170m of drilling took place at the Company's flagship Bisie North project. A maiden Mineral Resource Estimate was prepared for the company by The MSA Group (Pty) Ltd ("MSA") , detailed below. Subsequent to the reporting period, between January 2026 to April 2026, further drilling of 3,250m was achieved. Rome has completed a total of 9,780m of core drilling since its admission to trading on AIM in July 2024. Project Background The Bisie North Project is situated in eastern DRC, some 250km southwest of the city of Kisangani. The Bisie North Project is contained across two licences - PR15130 and PEPM13274 with a total area of 35 km2. The world-class Alphamin tin mine at Bisie North, the highest tin grade mine in the world, is situated 8km to the southeast of Rome's field camp, which services exploration activities at the Mont Agoma and Kalayi drillsites as well as wider exploration activities. Whilst the area is heavily forested and the bedrocks poorly exposed, a large tin-bearing granite has clearly been emplaced to the south of the licence area, responsible for releasing mineral-rich fluids into the surrounding host rock, the emplacement of these minerals being controlled further by NW-SE trending shear zones within the host rock metasediments. Tin, copper, zinc and other mineral phases are associated with these near-granite shear zones and are well-documented in the Bisie Mine. Mineralisation appears to increase towards the granite, but in both the Bisie Mine and Rome's acreage it is not exposed. It is likely the contact between the granite and the host rocks in Rome's licences runs along the course of the Oso River in the south of the licences. The 2026 airborne geophysical survey is anticipated, among other things, to better define this key geological contact. Mineralisation has been encountered to date in two areas in the Rome licence areas - Kalayi and Mont Agoma. Kalayi is a pure tin play with cassiterite (tin oxide ore) found associated with quartz veins in sheared metamorphic zones. Several steeply dipping high grade tin ore shoots are seen in Kalayi, striking northwest-southeast and dipping to the northeast. Mont Agoma, en echelon with Kalayi, is similarly hosted in steeply dipping metamorphics though contains significant sulphide deposits in terms of copper and zinc, with tin and silver. The sulphide mineralisation, which is pervasive and high grade, is about 200m wide and with significant volume potential for copper and zinc, with additional silver and tin credits. Operations The Company continued its campaign of core drilling on the Mont Agoma and Kalayi deposits through 2025. The majority of 2025 concentrated on Mont Agoma, whilst the subsequent early 2026 campaign focused on Kalayi. The drilling performance has been greatly improved following the addition of an external drilling supervisor and alternative drilling crews. Drilling operations in remote areas requiring helicopter support are prone to lengthy delays if spare parts are required at short notice. Consequently, planning ahead of potential downtime events has improved the overall drilling rates and as a consequence the per metre cost of drilling activity. During May 2025 the advance of the M23 forces out of the Goma area towards the local hub of Walikale prompted a short shutdown and evacuation of both Rome and Alphamin personnel. This was out of an abundance of caution and the M23 forces did not get closer than Walikale (70 km from site) before retreating back to the east. The shutdown lasted 40 days and subsequent to this there have been no issues and no trigger points have been crossed to warrant further action. It is our understanding that exports from the nearby Alphamin mine have continued uninterrupted since the restart of operations. 2025 Mineral Resources Estimate Following the completion of the Company's 2024/2025 drilling programme at Rome's Kalayi and Mont Agoma prospects, the Company engaged MSA to prepare a maiden Mineral Resource Estimate (MRE) in respect of its Bisie North project, key findings are summarised below. The maiden MRE assesses the volumes associated with the tin intercepts previously reported at Kalayi and Mont Agoma along with the copper, zinc and silver encountered in Mont Agoma. The Eastern Tin Zone, seen in the shallow weathered zone of a single drillhole at Mont Agoma, was not included in the maiden MRE, as it awaits confirmation from further drilling. The Bisie North maiden MRE is based on diamond drillholes that were drilled from 2023 to 2025 by Rome. The Mont Agoma maiden MRE is based on the results of 33 diamond drillholes and there were eighteen diamond drillholes completed at Kalayi. The maiden MRE was prepared in accordance with the CIM Best Practice Guidelines and was reported in accordance with the 2014 CIM Definition Standards for Mineral Resources & Mineral Reserves. Mont Agoma Mont Agoma is a 200m wide polymetallic zone hosted in steeply dipping sheared metavolcanics and metasediments. It is believed the metavolcanics are the source for the sulphide phases of copper and zinc, whereas the tin granite to the south is responsible for the delivery of tin oxide bearing fluids in a separate mineralisation event associated with chloritisation. The Mont Agoma MRE is reported using a net smelter return cut-off of 90 USD/tonne. A summary of the Mont Agoma MRE is presented in Table 1 (as announced by the Company on 30 October 2025). Table 1 Mineral Resource Estimate for Mont Agoma as at 29 October, 2025 at a 90 USD/tonne NSR cut- off Category Tonnes (Mt) NSR (USD/t) Cu (%) Sn (%) Zn (%) Ag (g/t) Cu (kt) Sn (kt) Zn (kt) Ag (Moz) Inferred 3.16 166 1.45 0.19 2.72 14.3 45.9 6.1 86.2 1.46 Total 3.16 166 1.45 0.19 2.72 14.3 45.9 6.1 86.2 1.46 Mont Agoma mineralisation starts at surface, as evidenced by strong copper and tin soil anomalies. As is common in a large number of global copper-tin deposits, the copper dominates the shallow part of the zone, with tin strengthening at depth, Mont Agoma's shallow drilling to date has encountered significant high grade copper, with thinner, lower grade tin intercepts. As in the Bisie Mpama mines to the southeast, it is anticipated these tin grades and intercepts will increase at depth, as is also seen in Kalayi. Kalayi Kalayi is a simple tin-only mineralised system present in multiple steeply dipping shoots of quartz veins hosted in a NW-SE striking chloritised metasediment zone. The Kalayi MRE is reported at a cut-off grade of 0.85% tin (Sn). A summary of the Kalayi MRE is presented in Table 2 (as announced by the Company on 30 October 2025).. Table 2 Mineral Resource Estimate for Kalayi as at 29 October, 2025 at a 0.85% Sn cut-off Category Tonnes (Mt) Sn Grade (%) Sn Content (kt) Inferred 0.33 1.36 4.47 Total 0.33 1.36 4.47 Earlier drilling of the Kalayi tin deposit, which is present from surface, has proven narrow, yet high grade shallow intercepts which have given way to wider high-grade intercepts at depth with subsequent early-2026 drilling. Further drilling following the end of the reporting period drilled significantly wider high grade tin intercepts in Kalayi than previously encountered. These intercepts are now in the process of being assayed and will feed into a revised mineral resource estimate in due course. Metallurgical Studies Whilst the Kalayi tin ore exhibits a simple single-commodity chemistry, the Mont Agoma ore has significant copper and zinc which it is necessary to assess for recovery in the processing design. Samples of copper and zinc ore were delivered from the Mont Agoma deposit to the SGS laboratory in Lakefield, Canada. These samples were subjected to mineralogical and exploratory metallurgical testing to determine the amenability to commercial extraction. The results of these tests were highly encouraging. Copper The main copper mineral in the copper ore sample is chalcopyrite (8.2%) with minor chalcocite (0.1%) and the sample assayed 2.92% copper and 0.78% zinc. The sample responded well to flotation processes and there is scope to pre-concentrate the flotation feed with gravity and magnetic separation due to the quartz and iron oxides content reported in the mineralogy. Rougher flotation delivered a concentrate of 8.9% Cu with a copper recovery of 97%. The first timed rougher concentrate graded 18% Cu indicating that cleaner flotation would deliver a concentrate suitable for smelting. Zinc The main zinc mineral in the zinc ore sample is sphalerite (27.1%), which assayed at 13.5% zinc. The ore responded well to flotation with recoveries over 99% to concentrate. Rougher flotation delivered a concentrate grading 37.1% Zn with a zinc recovery of 99.1%. The first timed rougher concentrate assayed 52.1% Zn with a zinc recovery of 89.6%, indicating that cleaner flotation should deliver a concentrate suitable for smelting. Canadian Critical Minerals Project Post year end, on 10 March 2026, it was announced that Rome entered into the Option Agreement, covering a number of mineral claims that were posted in the region of the Mount Douglas Granite, a Devonian-age tin-tungsten enriched granite system associated with the Mount Pleasant deposit. Under the Option Agreement and as operator of the licence associated with the Option Agreement, Rome will fund an exploration programme to evaluate the previously identified mineral showings, primarily of tin and tungsten. This programme, to be conducted through the summer season of 2026, will be a combination of soil sampling and trenching. On Schoular Mountain, 3km east of the undeveloped Mount Pleasant Fire Tower tin zone, surface sampling will take place along historical IP profiles which showed encouraging resistivity response. In the Square Lake area, surface sampling around historical workings will be taken and assessed for molybdenum and tin potential. Finally, the Victoria Lake cluster of tin-bearing greisen occurrences will be sampled by trenching in order to assess their extent and suitability for drilling in 2027. The Directors believe that this initial entry into the Maritimes critical mineral play, at a time when the Province of New Brunswick is operating an active strategy of mineral resource development against the global supply constraint outlook, is extremely timely. Local Communities, Health, Safety and Environment The Company maintains a strong commitment to the local community in the Bisie region. Demonstrating this commitment, over 40 local personnel are employed to manage both the day-to-day aspects and the security of the operation during the drilling phase along with Congolese national technical staff. The Company maintains a good relationship with the small artisanal operators in the stream section at Kalayi. There have been no lost-time incidents or environmental incidents reported during the reporting period. The environmental footprint of the operation is minor. The Board note the recent Ebola outbreak in the DRCX. Whilst the outbreak is currently not affecting the region in which the Group operates, nor in any of the transit routes used by Rome's staff, the Board continue to monitor the situation closely. Mozambique Legacy Claim There has been limited progress with the settlement of the claim, which came about as a result of the expropriation of a historical ilmenite sand licence in Mozambique. As announced by the Company on 20 March 2025, while it was agreed that 5 replacement licences would be allocated to IM Minerals, the Company has received no confirmation that this has taken place. The Directors continue to pursue a resolution but note that the Company's existing operations will not be significantly impacted by this process. Outlook After a year of intense exploration activity, the Company is poised to update the Kalayi tin mineral resource estimate and quantify the additional exploration potential from an airborne geophysical survey. Additional drilling on Mont Agoma is anticipated in order to drill the previously defined copper and tin exploration targets. The Directors are working towards a commercial solution for both the Kalayi tin and the Mont Agoma polymetallic assets as well as developing the promising early-stage critical minerals project in Canada. It is expected that this year will deliver results on all of these fronts. Paul Barrett Chief Executive Officer 24 June 2026 Directors and strategic report for the Period Ended 31 December 2025 Overview It has been an active year for the Company, pressing ahead with the drilling of both Mont Agoma and Kalayi, resulting in the publication of a maiden Mineral Resource Estimate. Drilling continued into 2026 with the aim of adding additional resource through deeper drilling. In addition, also in early 2026, the Company entered into the Option Agreement in connection with areas of an exciting tin-tungsten play in eastern Canada. The Company appreciates the continued support of its shareholders in facilitating funding of the venture through 2025 and into 2026. Cash Balance The Group's cash balance as at 31 December 2025 was £1,418,000 (2024: £4,485,000). Dividends The directors do not recommend the payment of a dividend (2024: £nil). Events since the end of the year Information relating to events since the end of the year is given in note 19 to the financial statements. Directors The directors who held office at any time during the year ended 31 December 2025 are as follows: P Barrett K Eckhof M Gasson (resigned 14 November 2025) E Etienvre (resigned 11 December 2025) M Mathenz (resigned 11 December 2025) S Tschitembu (resigned 1 September 2025) The Company has agreed to indemnify its directors against claims against them by reason of the fact that they are or were a director of the Company, and the Company has in place a directors and officers insurance policy. The Board of Directors is responsible for overseeing the long-term success and strategic direction of the Company in accordance with the schedule of matters reserved for board decision and is responsible for monitoring the activities of the executive management. Directors' interests in shares As at 31 December 2025, the interests of the directors' beneficial interests in the shares of Rome Resources Plc (including the beneficial interests of their immediate family) were as follows: No. shares held at 31 December 2025 No. shares held at 31 December 2024 Paul Barrett 13,610,108 3,610,108 Klaus Eckhof 439,624,500 475,724,500 Details of directors' remuneration is disclosed in Note 4. Details of directors' interests in share options and warrants is given in Note 16. Political donations and expenditure No charitable or political contributions were made during the current or previous year. Significant shareholders As at 22 June 2026, the registered holders of 3% or more of the Ordinary Shares were as follows: Shareholder No. of Ordinary Shares held % of issued share capital held Stanvic Mining SARL 1,200,000,000 15.63% Andreas Reitmeier 490,075,000 6.38% Klaus Eckhof 439,624,600 5.73% The Estate of Mark Gasson 401,351,600 5.23% Principal risks and uncertainties Liquidity risk The Group has no revenue at the present time and is therefore dependent upon the availability of additional equity finance, which is described in further detail in note 1 to the financial statements under the going concern section of the accounting principles. The availability of additional funding could be influenced by a wide range of factors and risks. Political Risk The company's operations are in the democratic Republic of Congo, where unrest and ethnic violence has been a factor in the east of the country for several decades. Whilst the operations continue as normal for the most part, there are occasions where, out of an abundance of caution, the Company pauses its operations. However, the emergence of commercial arrangements with the US government on minerals in the DRC, including the potential for security guarantees, has reduced the perceived risk from insurgents. This has been underscored by International Resource Holding's (owned by the Abu Dhabi Sovereign Wealth fund) C$503 million acquisition of a 56% stake in the Alphamin tin mine, close by Rome's area of operation. Dependence on key personnel The Group and Company is dependent upon its executive management team. Whilst it has entered into contractual agreements with the aim of securing the services of these personnel, the retention of their services cannot be guaranteed. The development and success of the Group depends on its ability to recruit and retain high-quality and experienced staff. The loss of the service of key personnel or the inability to attract additional qualified personnel as the Group grows could have an adverse effect on future business and financial conditions. Financing risk The Group has an ongoing requirement to fund its activities through the equity capital markets. There is no certainty such funds will be available when needed. To date the Group has managed to raise the required funds, primarily through equity placements, including placements undertaken during difficult market conditions. The Directors have prepared cash flows forecasts for at least the next 12 months from the date of this report and are confident that the Company will be able to access sufficient financial resources to fund its operations through further equity raises as required during the period. Health and safety risk The Group's primary operations are based in the DRC, a country that is currently experiencing an outbreak of Ebola. Whilst the outbreak is currently not affecting the region in which the Group operates, or which the Company's staff travel through, the Company continues to monitor the situation and continually assesses the risks associated with the virus outbreak spreading to the region and how that may impact the Group's workforce, local communities and its operations. Internal controls and risk management The directors are responsible for the Group's system of internal financial control. Although no system of internal financial control can provide absolute assurance against material misstatement or loss, the Group's system is designed to provide reasonable assurance that problems are identified promptly and dealt with appropriately. In carrying out their responsibilities, the directors have put in place a framework of controls to ensure as far as possible that ongoing financial performance is monitored in a timely manner, that corrective action is taken and that risk is identified as early as practicable. The directors keep under constant review, the effectiveness of the internal financial controls, with a strong focus on monitoring the cash position and future cash flows of the business. Disclosure in the strategic report Strategic matters relating to the Company throughout the reporting period, including the main trends and factors likely to affect the future development, performance and position of the business, are outlined in the Chairman's Statement. Section 172 Statement The Directors have a duty under Section 172 of the Companies A
