Half-year Results

Critical Mineral Resources plc (LON:CMRS), the Morocco-focused mining exploration and development company, is pleased to announce its unaudited interim results for the six months ended 30 June 2026 ('H1 2026' or the 'Period').

Key Investment highlights in H1 2026

• Drilling programme that started in September 2025 performed well throughout H1 2026.
• Drilling rates ramped up in 2026, with some Zone 1 intercepts averaging >5m true width - more than double the Company's 2m average-width assumption - supporting an open-pit development scenario, with less than 5% of the project area drill-tested to date.
• Excellent near surface drill results include 5.0m at 1.20% copper, 0.77g/t Au and 1.4g/t silver from 24m, 3.7m at 1.76% copper and 8.6g/t silver from 6.3m, 4.0m at 1.20% Cu and 0.9g/t Ag from 18m, and 3.6m at 0.98% Cu and 6.22g/t Ag from 29.3m.
• Appointment of Géraud Moussarie as Chairman of the Board in February 2026 brought significant additional leadership experience in the management of natural resources and infrastructure projects across North and West Africa. Géraud chaired a board meeting in Casablanca in June 2026 following a site visit, and met JV partners and key local stakeholders, further strengthening our strategy.
• The Company raised total gross funds of approximately £3.1m through equity placings and warrant exercises. This enabled the acceleration of our drilling and exploration work on site as well as further contiguous bolt-on acquistions to expand beyond the 65km2 landpackage.
• As a result CMR's balance sheet evolved positively from net liabilities of £1.02m at 31 December 2025, to net assets of £3.35m at 30 June 2026, with cash of £1.20m (31 December 2025: £0.09m), following the equity raise and the conversion of convertible loan notes by strategic investors, which reduced total liabilities by £2.3m to £0.88m.
• The business is well positioned to deliver on our H2 milestones, including a maiden Mineral Resource Estimate in Q4 2026.

Post period

• Step-out drilling at Zone 1 North made a new high grade silver discovery associated with a NNW trending fault.
• Hole 174 returned 1.6 m at 1.67% Cu, 695 g/t Ag and 0.40 g/t Au, including an exceptionally high-grade 0.2m interval 10.24% Cu, 5,390 g/t Ag and 2.80 g/t Au.
• Hole 175, 50m east of 174 returned 1.0m at 0.72% Cu, 402 g/t Ag and 0.36 g/t Au.
• The Company appointed Brett Capper (ex-GM of Project Development of Asia Pacific & Global Project Shaping at Rio Tinto) as the Chair of the Company's Technical Committee.

Charles Long, Chief Executive Officer of CMR PLC, commented:

"The first half of 2026 saw excellent progress on the ground as we prioritised the development of Agadir Melloul, our new copper silver discovery in the Western Anti Atlas. Significant value was added through the ongoing diamond drilling programme and further key development milestones. Notably in Q1, both a mining license and environmental permit for extraction were awarded, and in June we began the processing plant development work. This includes a second phase of metallurgical testwork, building on a successful first phase, a pilot plant metallurgical programme, and a survey to determine the optimal plant and tailings dam locations, all being led by the Marrakech based laboratory and metallurgical consultants Afrilab Group.

In terms of personnel, our team is in a great place. Géraud Moussarie joined as Chairman in February and just recently Brett Capper joined as Chair of our Technical Committee. Both are already making a meaningful contribution to CMR and its projects, adding value and reducing risks across the Company and its projects. Géraud's experience at larger companies and specifically in the north African resources industry has given CMR a welcome boost on a number of fronts, not least leveraging his long-term relationships with certain institutional investors and development banks, strong in-country government relations and a step-up in our governance. Brett will be leading the feasibility study, ensuring that the planning and engineering work for Agadir Melloul, and other future projects, continue to meet the standards expected by our partners and current and future stakeholders.

On the drilling front, during H1 we received some of the best assays results since drilling started in September 2025, and we now have sufficient data to publish our maiden mineral resource estimate this year, as planned. Once this is in place, we intend to accelerate the Agadir Melloul feasibility study and advance to a construction decision as soon as possible.

Approximately 25% of holes drilled to date have intersected good widths and copper grades and critically these are within large continuous zones, which is characteristic of the nature of this deposit. Our drill hole locations are selected by extending known areas of mineralisation identified by previous holes, channel samples, trenching and mapping, what our resource consultants call 'walk-up targets'. Some of the mineralised areas extend for hundreds of metres, whilst some are smaller.

In practice this means the maiden resource is expected to be more than sufficient to support an initial mine development, and more importantly, provide a strong foundation for growing Agadir Melloul into a strategically important asset over the medium to longer term. We have a pipeline of walk-up targets that we expect to sustain our drilling programme for at least two to three years, potentially longer. As we gather more data, our understanding of the mineral systems will improve, enabling us to target hidden areas of mineralisation. I use the term mineral systems, because alongside the Zone 1 sedimentary copper, we have also found an igneous copper-silver mineralisation in Zone 2 north, and most recently what appears to be a silver structure with our first intercept of massive sulphides.

Whilst it is still early days, this is a highly encouraging development. The massive sulphide intercept in hole 174 assayed grades of 5.4kg/t silver, 10.24% copper and 2.80g/t gold. This is extremely valuable rock, on a gross metal value basis, the silver content alone is worth US$10,000/t. This has the potential to add a separate high-grade deposit at Agadir Melloul."

Chairman's Statement

I joined the CMR Board in February 2026 with real excitement. Agadir Melloul has the hallmarks of a project that can define a company: shallow, laterally extensive copper-silver mineralisation in a mining-friendly jurisdiction. CMR is led by a management team that works hard and with deep passion, with the support of its long-term investors and partners. Much of the hard initial work of securing the ground and preparing to explore has been accomplished, and a maiden JORC Mineral Resource Estimate is expected in Q4 2026. Eight months on, it is worth pausing to look back at how far CMR has come in a remarkably short period.

From explorer to developer

In 2023 the Company became Critical Mineral Resources and committed itself to Morocco, acquiring an 80% stake in Atlantic Research Minerals, providing an experienced in-country technical team from the outset. With the backing of its historical and new investors from early 2025, the Team moved forward decisively.

In May 2025 a joint venture agreement was signed with Coppernicus Mining Company, and the CMR team swiftly secured further permits and exclusivity over additional ground, consolidating a district-scale land package of c.65km² ahead of competition. Drilling began in September 2025, a second rig followed in December, with results beating expectations, including gold discoveries in certain areas and a new igneous-hosted copper-silver mineralisation in the rhyolite.

In the first quarter of 2026, a mining licence and an environmental permit for extraction were awarded - a milestone that exploration companies sometimes take years to reach. By April, drilling was running at approximately 1,200m per month and returning intercepts of c.5m true width in places, more than double the base-case assumption. In June, the planning of the initial processing plant work began. Since the end of the Period, Addison Mining Services has been appointed to deliver our maiden JORC Mineral Resource Estimate, and step-out drilling has identified what may be a separate high-grade silver structure, a reminder that Agadir Melloul is still revealing its potential.

Stronger foundations

Operational progress has been supported by a stronger financial position. The Company raised approximately £3.1m during the Period and, together with the conversion of loan notes by our strategic investors, this has improved the balance sheet from net liabilities of £1.0m at the year end to net assets of £3.3m at 30 June 2026. In 2026, the Team has strengthened its governance processes and technical oversight. I was thrilled to recently welcome Brett Capper as Chair of the Technical Committee, with a mission to lead our efforts with the feasibility study.

Looking ahead

The coming months are among the most important in the Company's history. The maiden Mineral Resource Estimate, expected in Q4 2026, will provide the first independent measure of what we have explored to date, covering only around 5-6% of our permit area. Metallurgical, engineering and environmental workstreams are advancing in parallel towards a feasibility study and, in turn, a construction decision. Alongside this, the Board will remain disciplined in evaluating further opportunities, pursuing them only where they are material and value-accretive for shareholders.

On behalf of the Board, I would like to thank our shareholders for their continued support, our joint venture partner Coppernicus, the Moroccan authorities, and Charlie and the team, whose persistence has taken Agadir Melloul from an opportunity to a project with a clear path to development.

Notes to the condensed interim financial statements

General information

The principal activity of the Company and its subsidiaries (the Group) is in mineral exploration and the development of appropriate exploration projects. The Company's registered office is at Eccleston Yards, 25 Eccleston Place, London, SW1W 9NF. Its shares are listed on the Main Market of the London Stock Exchange under the ticker "LON:CMRS", in the "Equity Shares - Transition" category. On 17 August 2023 the Company changed its name from Caerus Mineral Resources PLC to Critical Mineral Resources PLC.

BASIS of PREPARATION

These condensed interim financial statements for the six months ended 30 June 2026 have been prepared in accordance with UK-adopted IAS 34 'Interim Financial Reporting' and the Disclosure Guidance and Transparency Rules of the Financial Conduct Authority, using the accounting policies adopted in the Group's annual financial statements for the year ended 31 December 2025. They do not include all the information required for full annual financial statements and should be read in conjunction with those financial statements and any public announcements made by the Company during the period.

These condensed interim financial statements, and the comparatives for the six months ended 30 June 2025, are unaudited and have not been reviewed by the auditor. They do not constitute statutory accounts as defined in section 434 of the Companies Act 2006. The comparatives for the year ended 31 December 2025 are extracted from the Group's statutory financial statements for that year, which have been delivered to the Registrar of Companies. The auditor's report on those financial statements was unqualified, included a material uncertainty related to going concern without modifying its opinion, and did not contain a statement under section 498(2) or (3) of the Companies Act 2006.

The business is not considered to be seasonal in nature.

The condensed interim financial statements have been approved for issue by the Board of Directors

on 28 September 2026.

New standards, amendments and interpretations adopted by the Group.

During the current period the Group adopted all the new and revised standards, amendments and interpretations that are relevant to its operations and are effective for accounting periods beginning on 1 January 2026. This adoption did not have a material effect on the accounting policies of the Group.

New standards, amendments and interpretations not yet adopted by the Group.

The standards and interpretations that are relevant to the Group, issued, but not yet effective, up to the date of these interim Financial Statements have been evaluated by the Directors and they do not consider that there will be a material impact of transition on the financial statements.

Going concern

The condensed interim financial statements have been prepared on the going concern basis. Under this basis, an entity is ordinarily viewed as continuing in business for at least 12 months from the date of Board approval of the financial statements, with neither the intention nor the necessity of liquidation, ceasing trading or seeking protection from creditors pursuant to laws or regulations. The Group is not currently generating revenues and therefore an operating loss has been reported and is expected in the 12 months following the date of these condensed interim financial statements.

During the period the Company received substantial funds through the issue of equity. The Group is reliant on the continuation of such funding and will need to secure further financing within the 12 months following the approval of these condensed interim financial statements in order to fund working capital requirements and project investment. These conditions indicate that a material uncertainty exists that may cast significant doubt on the Group's and the Company's ability to continue as a going concern.

The Directors have prepared cash flow projections for the 12 months from the date of approval of these condensed interim financial statements, which include the expected further financing. Based on these projections, and after considering reasonably possible downside sensitivities, the Board, whilst acknowledging this material uncertainty, remains confident that the required financing will be secured. The Directors have therefore concluded that there is a reasonable expectation that the Group has adequate resources to continue in operational existence for the foreseeable future, and have adopted the going concern basis in preparing these condensed interim financial statements.

Risks and uncertainties

The Directors continuously assess and monitor the key risks of the business. The key risks that could affect the Group's medium-term performance and the factors that mitigate those risks have not substantially changed from those set out in the Group's most recent annual financial statements for the year ended 31 December 2025.

Critical accounting estimates

The preparation of condensed interim financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the end of the reporting period. Significant items subject to such estimates are set out in Group's most recent annual financial statements for the year ended 31 December 2025. The nature and amounts of such estimates have not changed during the interim period.

SEGMENTAL REPORTING

For the purpose of IFRS 8, the Chief Operating Decision Maker "CODM" takes the form of the board of directors. The Directors are of the opinion that the business of the Group focused on two reportable segments as follows:

• Head office, corporate and administrative, including parent company activities of raising finance and seeking new investment opportunities, all based in the UK and
• Mineral exploration, all based in Morocco

The geographical information is the same as the operational segmental information shown below.

EARNINGS PER SHARE

The calculation for earnings per Ordinary Share (basic and diluted) is based on the consolidated profit/(loss) attributable to the equity shareholders of the Company is as follows:

Earnings per Ordinary share are calculated using the weighted average number of Ordinary shares in issue during the period. Diluted earnings per share have not been calculated as the difference in value would be negligible and the shares to be issued are not included in the above calculation.

EQUITY ACCOUNTED INVESTEES

Agamel Minerals SARL is a Moroccan SPV established to hold the permits and manage the Agadir Melloul Project. The Group has joint control over the relevant activities of Agamel Minerals SARL because key decisions are subject to unanimous shareholder approval. Accordingly, the arrangement is classified as a joint venture and is accounted for using the equity method. The Group currently holds a 20% economic interest in the SPV.

The Group's carrying amount of the investment includes shareholder advances provided to fund project activities, including exploration expenditure and permit acquisition costs, which form part of the Group's net investment in the joint venture.

Summarised financial information

Summarised financial information of the joint venture (100%) and the Group's share are presented below using the most recent financial statements of Agamel Minerals SARL available at the reporting date.

On the 28th April 2026, the Company converted two CLNs of £425,000 and £462,474 respectively and interest was paid in ordinary shares.

The following table sets out the remaining CLNs as at 30 June 2026:

At 30 June 2026, 43,872,531 Ordinary shares remained to be issued following the conversion of the £425,000 CLN on 28 April 2026.

WARRANTS

The following table sets out the movement of warrants during the period:

RELATED PARTIES

Other than Directors' remuneration in the normal course of business, the related party transactions during the period were the advances to the joint venture, Agamel Minerals SARL (note 7), and the share issues to Gilini Holdings Limited, of which Russell Tucker, a Director, is an employee (notes 9 and 10). Balances and transactions between the Company and its subsidiaries have been eliminated on consolidation.

SUBSEQUENT EVENTS

The Directors confirm that there have been no events subsequent to the interim period end of 30 June 2026 which would have a material impact on these financial statements.
