Charles Manners, Executive Chair, commented:

“In H1 2026 Strategic Minerals moved the Redmoor project decisively into its next phase. An updated Inferred Mineral Resource Estimate 49% larger than before, materially improved metallurgy and a base case NPV of US$1.54 billion have now put Redmoor firmly on the map as Europe’s highest-grade undeveloped tungsten project. With £8.7m of cash raised in the first quarter, the Company is now fully funded to deliver the largest drilling programme in Cornwall this century and substantially funded to take Redmoor through pre-feasibility, backed by the cash flow from Cobre and the sale of Leigh Creek. Against a backdrop of record tungsten prices and with growing emphasis on security of supply, our strategy is focused on delivering Redmoor into production as quickly as possible.”

CHAIRMAN’S STATEMENT

Introduction

In H1 2026 Strategic Minerals moved the Redmoor Tungsten-Copper-Tin Project in Cornwall (“Redmoor”) from a successful first drilling campaign into the pre-feasibility phase. The results of the drilling programme, which completed in March 2026, produced an updated Inferred Mineral Resource Estimate 49% larger than its predecessor and an Economic Sensitivity Analysis with a Base Case after-tax NPV(8%) of US$1.54 billion. Strong investor demand, including a subscription led by a prominent international investor, enabled the Company to raise £8.7m in the first quarter, funding a 22,500m infill and upgrade drilling programme that is now the largest of its kind in Cornwall this century. The Cobre magnetite operation in New Mexico continues to provide a very valuable and reliable cash-generating base for the Group.

Financial Results

The Cobre magnetite operation in New Mexico is the current revenue generator in the Group. Revenues in the Period were US$1,594,000 (H1 2025: US$2,001,000), a decrease of 20%, The revenue decline was driven by a temporary fall in purchase volumes from the largest buyer in January and February, which have subsequently reverted to long-term average levels.

Gross margin was maintained at 86% and Cobre contributed a segment profit before tax of US$701,000.

The Group moved into a substantially larger operating phase at Redmoor, with an expanded technical team and site facilities, and Group overhead expenses increased to US$1,189,000 (H1 2025: US$949,000). In addition, a non-cash share-based payment charge of US$812,000 was recognised in respect of the 88,675,000 options granted in February 2026 to Cornwall Resources employees, Directors and advisers, which vest over two years.

As a result, the Group recorded a loss before tax of US$712,000 (H1 2025: profit of US$568,000) and a loss after tax of US$995,000 (H1 2025: profit of US$151,000). Excluding the non-cash share-based payment charge, the Group would have reported a profit before tax of US$100,000. We remain committed to keeping Board costs lean while deploying capital into Redmoor, evidenced by an 18% reduction in head office overhead versus H1 2025.

Bolstered by two equity fundraisings – £4.0m raised at 1.3 pence per share in January and £4.7m raised at 3.5 pence per share in March – the Company ended the Period with US$10,026,000 of cash (31 December 2025: US$777,000) and net assets of US$17,549,000 (31 December 2025: US$7,104,000). During the Period US$1,119,000 was invested in exploration and evaluation at Redmoor (H1 2025: US$378,000).

The Directors consider the Group to be fully funded for all planned activities for more than 12 months from the date of this report, including the Redmoor infill drilling programme and substantially through the Prefeasibility Study.

Cornwall Resources Limited (“CRL”)

Redmoor Tungsten-Copper-Tin Project, Cornwall, UK (“Redmoor”)

Results from the 2025 drilling programme - The 5,048.7m drilled at Redmoor between June and December 2025 continued to deliver in the Period. Assay results from Pads 2 and 3 confirmed Sheeted Vein System (“SVS”) mineralisation within the previously untested Exploration Target. In March, hole CRD039 returned 0.60m @ 18.96% WO₃, 2.76% Sn and 3.19% Cu (22.09% WO₃Eq), the highest tungsten-equivalent sample interval ever drilled at Redmoor, together with 1.52m @ 7.45% Sn, the highest-grade tin intersection at the project. In February, the Company confirmed the discovery of a new, laterally continuous tin-dominant structure north of the SVS, the North Tin Zone. Re-analysis of 428 historical pulp samples using a more appropriate method for tin in cassiterite showed higher tin grades in 78% of samples, and further analysis of CRD041 core in June identified additional tin-rich structures outside the modelled resource, including 1.00m @ 0.67% Sn.

Metallurgy - In March, a metallurgical study increased overall tungsten recovery from 72.0% to 85.8%, a 19.2% relative improvement, and demonstrated for the first time that silver is recoverable to the copper concentrate (58.7% recovery at 270g/t). Tin and copper recoveries were broadly unchanged at 67.2% and 82.4% respectively, with further improvements identified for the Pre-Feasibility Study.

Mineral Resource Estimate and economics - On 26 March 2026 the Company published an updated JORC (2012) Inferred Mineral Resource Estimate of 17.4Mt @ 0.65% WO₃Eq (0.49% WO₃, 0.17% Sn, 0.44% Cu, 5.8g/t Ag), representing a 49% increase in tonnage compared with the 2019 estimate. Contained metal increased by 31% for tungsten, 55% for tin and 30% for copper, and the potential mine life at the 2020 Scoping Study production rate increased from 12 to 29 years. An Exploration Target of 1.8–3.4Mt has also been identified outside the current resource. At 0.49% WO₃, Redmoor is Europe’s highest-grade undeveloped tungsten project compared with other CRIRSCO-compliant projects.

The accompanying Economic Sensitivity Analysis, prepared by Snowden Optiro, updates the 2020 Scoping Study for the new resource, metallurgy, cost inflation and metal prices. Indicative pre-production capital cost is US$109.7m. After-tax results by scenario were:

• Base Case (US$1,200/mtu APT): NPV(8%) of US$1.54 billion, IRR 40%
• Upside Case (US$1,800/mtu APT): NPV(8%) of US$2.71 billion, IRR 55%

Southern Minerals Group LLC (“SMG”)

Cobre magnetite stockpile, New Mexico, USA

Cobre continued to generate positive cash flow, with revenues of US$1,594,000 in H1 2026 (H1 2025: US$2,001,000). The revenue decline was driven by a temporary fall in purchase volumes from the single largest buyer in January and February, which have subsequently reverted to long-term average levels.

In June, the Company announced a substantial investment in new equipment, including a Caterpillar D6 bulldozer, reinforcing its long-term commitment to the site while improving year-round capability and reducing reliance on rented equipment. Post-Period end, SMG agreed a further two-year extension of its access to the Cobre stockpile, from 31 March 2029 to 31 March 2031, providing greater certainty over an important source of internal cash flow.

Leigh Creek Copper Mine Pty Ltd (“LCCM”)

Leigh Creek Copper Project

In December 2025, Cuprum Metals (“Cuprum”) exercised its call option to acquire 100% of LCCM, and A$250,000 had been received by the Company in respect of the option and first instalment. The transaction timetable was extended by three months in June while Cuprum progressed funding. On 3 September 2026, following the Period end, the parties signed a Definitive Agreement, with completion subject to conditions including Australian Foreign Investment Review Board approval. With copper prices at all-time highs and forecast project economics improving, the Company agreed a lower upfront cash payment in return for a Net Smelter Royalty, giving continued exposure to future cash flows. Final consideration comprises A$750,000 in cash (A$500,000 of which is held in escrow pending FIRB approval); shares equivalent to up to 19.9% of a new entity intended to be listed, targeting a value of A$3.0m (any shortfall to be added to the earn-out); a 2% Net Smelter Royalty on the first 24,900 tonnes of copper production, with a 1% buy-out option for Cuprum on payment of A$1.5m; and an earn-out equal to 20% of half-yearly Operating Cash Flows, up to A$4.0m, from commencement of commercial production. All proceeds will be used to support Redmoor. The result of LCCM continues to be presented as a discontinued operation, with a loss of US$53,000 in the Period (H1 2025: US$38,000).

Board Changes and Share Options

In June 2026, Luke Rogers was appointed as an independent Non-Executive Director. Luke has over 15 years’ experience as a mining executive and engineer focused on critical and strategic minerals, is Technical Director at Balta SA, has held senior positions at Aterian PLC and TechMet Ltd, and is an elected Cornwall Councillor. The Board believes his combination of technical experience and local knowledge is well suited to the next phase at Redmoor, and appropriate arrangements are in place to manage any potential conflicts arising from his Council role. All resolutions were passed at the Annual General Meeting on 24 June 2026.

In February 2026 the Company granted 88,675,000 options at an exercise price of 3.5 pence, and post-Period end, in August 2026, granted a further 13,150,000 options at 4 pence, in each case to key CRL employees, Directors and (in February) advisers, vesting over two years, in recognition of progress and to support retention of key personnel as Redmoor advances towards development.

Safety

The Company maintains a strong safety culture across all operations. I am pleased to report that no significant safety incidents were recorded during the reporting period.

Outlook

Our overarching strategy is to grow the Company’s value by unlocking the significant potential of the Redmoor Project, using sustainable cash flows from Cobre and non-dilutive proceeds from the sale of Leigh Creek. With Redmoor now funded through the Pre-Feasibility Study, the priorities for the remainder of 2026 and into 2027 are the delivery of the 22,500m drilling programme, the associated metallurgical, geotechnical and hydrogeological testwork, and the completion of a further Mineral Resource Estimate update, aimed at Indicated classification. The market backdrop supports this focus: in its update of 17 September the Company noted that the six- and twelve-month average APT prices of US$2,960/mtu and US$1,930/mtu respectively were both above the US$1,800/mtu Upside Case in our Economic Sensitivity Analysis. With continued supply constraints, Chinese export restrictions and a growing emphasis on security of supply for defence and high-technology applications, the strategic value of a high-grade tungsten source in the UK is reinforced. Redmoor has the potential to become a leading source of critical and strategic minerals for western world supply chains, and we remain very focused on accelerating its development to unlock its true value.

CONSOLIDATED STATEMENT OF COMPREHENSIVE INCOME

Profit/ (loss) per share attributable to the ordinary equity holders of the parent:

All comprehensive income is attributable to the owners of the parent Company.

NOTES FORMING PART OF THE CONSOLIDATED INTERIM FINANCIAL STATEMENTS

General Information

Strategic Minerals Plc (“the Company”) is a public company incorporated in England and Wales. The consolidated interim financial statements of the Company for the six months ended 30 June 2026 comprise the Company and its subsidiaries (together referred to as the “Group”).

Significant accounting policies

Basis of preparation

In preparing these financial statements the presentational currency is US dollars. As the entire group’s revenues and majority of its costs, assets and liabilities are denominated in US dollars it is considered appropriate to report in this currency.

These financial statements have been prepared in accordance with International Financial Standards and UK adopted international accounting standards in conformity with the requirements of the Companies Act 2006.

The preparation of financial statements in compliance with adopted IFRS requires the use of certain critical accounting estimates. It also requires Group management to exercise judgment in applying the Group's accounting policies. The areas where significant judgments and estimates have been made in preparing the financial statements and their effect are disclosed in note 2.

The financial statements have been prepared on a historical cost basis, except for the acquisition of LCCM and the valuation of certain investments which have been measured at fair value, not historical cost.

Going concern basis

The Directors have considered the Company’s and Group’s ability to continue as a going concern through review of cash flow forecasts prepared by management for a period of 12 months from the date of signing this report and a review of the key assumptions on which these are based and sensitivity analysis.

In January and March 2026, the Company raised gross proceeds of approximately £8.7m (approx. $12.0m) principally to advance the Redmoor Project through a Pre-Feasibility Study. As a result, the Group is fully funded for all planned activities for a period in excess of 12 months from the date of signing this report, and therefore the Directors do not consider there to be any going concern issues. Consequently, the financial statements have been prepared on a going concern basis.

New standards, interpretations, and amendments effective 1 July 2026:

Critical accounting estimates and judgements

Estimates

Carrying value of intangible assets

Management assesses the carrying value of the exploration and evaluation assets for indicators of impairment based on the requirements of IFRS 6 which are inherently judgemental. This includes ensuring the Group maintains legal title, assessment regarding the commerciality of reserves and the clear intention and financial ability to move the asset forward to development.

• The Redmoor Project is an early-stage exploration projects and therefore management have applied judgement in the period as to whether the results from exploration activity provide sufficient evidence to continue to move the asset forward to development. There are no indicators of impairment for the Redmoor Project in the period to 30 June 2026.
• The intangible asset associated with the offtake agreement for the LCCM project was impaired to nil at 31 December 2023. There has been no change to this assessment in the period to 30 June 2026.

Share based payments

The fair value of share-based payments recognised in the statement of comprehensive income is measured by use of the Black Scholes model after taking into account market-based vesting conditions and conditions attached to the vesting and exercise of the equity instruments. The expected life used in the model is adjusted based on management’s best estimate, for the effects of non-transferability, exercise restrictions and behavioural considerations. The share price volatility percentage factor used in the calculation is based on management’s best estimate of future share price behaviour based on past experience.

Carrying value of amounts owed by subsidiary undertakings.

IFRS9 requires the parent company to make certain assumptions when implementing the forward- looking expected credit loss model. This model is required to be used to assess the intercompany loan receivables from its subsidiaries for impairment. Arriving at an expected credit loss allowance involved considering different scenarios for the recovery of the intercompany loan receivables, the possible credit losses that could arise and probabilities for these scenarios.

The following were considered: the exploration project risk, the future sales potential of product, value of potential reserves and the resulting expected economic outcomes of the project.

Carrying Value of Development Assets

Management assesses the carrying value of development assets for indicators of impairment based on the requirements of IAS36 which are inherently judgemental.

The following are the key assumptions used in this assessment of Carrying value.

Mineable reserves over life of project

Forecasted Copper pricing

Capital and operating cost assumptions to deliver the mining schedule

Foreign exchange rates

Discount rate

Estimated project commencement date.

If the carrying amount of the Development asset exceeds the recoverable amount, the asset is impaired. The Group will reduce the carrying amount of the asset to its recoverable amount and recognise an impairment loss. The assessment is carried out twice per year – end of half year reporting period and end of annual reporting period.

Determination of incremental borrowing rate for leases

Under IFRS 16, where the interest rate implicit in the lease cannot be readily determined the incremental borrowing rate is used. The incremental borrowing rate is defined as the rate of interest that a lessee would have to pay to borrow, over a similar term and with a similar security, the funds necessary to obtain an asset of a similar value to the cost of the right-of-use asset in a similar economic environment.

Judgements

Investments in subsidiaries

Investment in subsidiaries comprises of the cost of acquiring the shares in subsidiaries.

If an impairment trigger is identified and investments in subsidiaries are tested for impairment, estimates are used to determine the expected net return on investment. The estimated return on investment takes into account the underlying economic factors in the business of the Company’s subsidiaries including estimated recoverable reserves, resources prices, capital investment requirements, and discount rates among other things.

Contingent consideration as part of Asset acquisition

Judgement was required in determining the accounting for the contingent consideration payable as per of the CRL acquisition. The group has an obligation to pay A$1m on net smelter sales arising from CRL production reaching A$50m and a further A$1m on net smelter sales arising from CRL production reaching A$100m.

Whilst a possible obligation exists in relation to the consideration payable, given the early stage of the project it was concluded that at reporting date it is not probable that an outflow of resources embodying economic benefits will be required to settle the obligation

Segment information

The Group has four main segments during the period:

 Southern Minerals Group LLC (SMG) - This segment is involved in the sale of magnetite to both the US domestic market and historically transported magnetite to port for onward export sale.

 Head Office - This segment incurs all the administrative costs of central operations and finances the Group’s operations. A management fee is charged for completing this service and other certain services and expenses.

 Development Asset – This segment holds the Leigh Creek Copper Mine Development Asset in Australia and incurs all related operating costs.

 United Kingdom - The investment in the Redmoor project in Cornwall, United Kingdom is held by this segment.

Factors that management used to identify the Group's reportable segments.

The Group's reportable segments are strategic business units that carry out different functions and operations and operate in different jurisdictions.

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision maker has been identified as the board and management team which includes the Board and the Chief Financial Officer.

Measurement of operating segment profit or loss, assets, and liabilities

The Group evaluates segmental performance on the basis of profit or loss from operations calculated in accordance with International Accounting Standards.

Segment assets exclude tax assets and assets used primarily for corporate purposes. Segment liabilities exclude tax liabilities. Loans and borrowings are allocated to the segments in which the borrowings are held. Details are provided in the reconciliation from segment assets and liabilities to the Group’s statement of financial position.

Revenues by key customers

Operating Loss

Leases

The Group has leases for an office, plant and machinery and a vehicle. Each lease is reflected on the balance sheet as a right-of-use asset and a lease liability. The Group classifies its right-of-use assets in a consistent manner to its property, plant and equipment.

Dividends

No dividend is proposed for the period.

Earnings per share

Earnings per ordinary share have been calculated using the weighted average number of shares in issue during the relevant financial year as provided below.

In January 2026 the Company issued 307,692,308 Ordinary shares of 0.1pence each at a price of 1.3 pence per share to raise gross proceeds of approximately £4,000,000.

In March 2026 the Company issued 134,285,712 Ordinary shares of 0.1pence each at a price of 3.5 pence per share to raise gross proceeds of approximately £4,700,000.

Share options and warrants

The following Options were in issue during the period:

These options vested in two tranches, 50% vesting 12 months after the date of issue and 50% vesting 24 months after the date of issue. The company recognises an expense in relation to the issue of these options over the vesting period, with $812,000 being recognised during the period from issue date to 30 June 2026.

Post balance date events

On 3 September 2026 the Group entered into a Definitive Agreement relating to the sale of LCCM, with completion subject to certain conditions. At the date of this report the proposed transaction has yet to be completed. The Directors consider that the entering into of the Definitive Agreement does not constitute an adjusting event for the purposes of IAS 10 and as such no adjustments have been made in these interim financial statements in relation to the carrying value of the Groups investment in LCCM which remain classified as assets and liabilities held for sale, with the development asset in LCCM remaining fully impaired.

Copies of this interim report will be made available on the Company’s website, www.strategicminerals.net.
