CHAIRMAN'S STATEMENT

Introduction

Strategic Minerals entered a new phase in H1 2025. The turnaround of the Cobre magnetite operation in New Mexico last year, and associated 200% revenue increase, provided a springboard for the Company to accelerate development of the Redmoor Tungsten-Tin-Copper Project in Cornwall ("Redmoor"). With match grant funding and strong investor demand to support the opportunity, Strategic Minerals was able to commission a £1.5 million, 12-month exploration programme including the first borehole drilling since 2018. This programme is in full swing.  

Financial Results

The Cobre magnetite operation in New Mexico is the sole revenue generating engine of the Group. It sustains Strategic Minerals and its main operating subsidiary, Cornwall Resources. The strong recovery in magnetite sales which drove the 200% revenue increase in FY 2024 held firm in H1 2025. A 10-day shutdown due to wildfires caused a slight reduction in sales of 6% in the Period to US$2,001,000 (H1 2024: US$2,136,000) which would otherwise have been consistent with the first half of 2024. We are confident of more than offsetting that lost revenue in the second half of this year, with Q3 2025 sales already looking very healthy.

Moving into an intense operating phase at Redmoor, upscaling headcount and facilities, naturally resulted in an increase in costs which impacted profitability in the Period. Furthermore, a number of one-off costs were incurred in the Period in connection with the restructuring of the Company's Board and the settlement in full of historical taxation due to the IRS in the USA. Pre-tax profit for H1 2025 was therefore US$568,000 (H1 2024: US$950,000) and post-tax profit was US$151,000 (H1 2024: US$667,000). This is a new regime, with a transformed Cobre operation and an accelerated development programme at Redmoor in motion. While the Company is appropriately deploying more investment into Redmoor, we remain committed to keeping Board costs lean.

Bolstered by an oversubscribed placing to raise gross proceeds of  c.£1.0 million which completed in May 2025, the Company ended the Period with US$1,532,000 of cash as at 30 June 2025 (31 Dec 2024: US$621,000). The strong investor demand reflects growing recognition of Redmoor's potential.

Cornwall Resources Limited ("CRL")

Redmoor Tungsten-Tin-Copper Project, Cornwall, UK ("Redmoor")

In April 2025, the Company announced that CRL was awarded c.£764,000 in match funding from the UK Shared Prosperity Fund under the Cornwall & Isles of Scilly Good Growth Programme. Together with the Company's oversubscribed placing, this has provided the c.£1.5m budget for a 12-month exploration project titled: "Exploration Drilling and Associated Activities to Enable Accelerated Development of the Redmoor Critical Minerals Project". Within the 12-month Project timeframe which began in April 2025, the Company aims to:

·    Undertake c.5,000m of new diamond core drilling and other associated activities

·    Complete the ongoing relogging programme of historical CRL core

·    Combine the results of new drilling and relogging with the aim to produce a new, upgraded and enlarged Mineral Resource Estimate ("MRE")

·    Update the economic model, using the updated MRE and incorporating the significantly increased commodity prices since the 2020 Redmoor Scoping Study was produced

·    Formulate an investment-ready business case and delivery plan, before the end of March 2026, for moving Redmoor into prefeasibility

By May 2025, drilling pre-commencement and enabling activities were well advanced, with drilling starting just before the end of the Period in late June 2025 - the first since 2018.

Nine new boreholes were planned for a total of approximately 5,300 metres of diamond core drilling over six months. Post-Period end, in September 2025, the first three boreholes were completed at Pad 1, intersecting the full thickness of the Redmoor sheeted vein system and confirming visible wolframite and chalcopyrite consistent with historic mineralisation. A second drill rig was mobilised to site, accelerating the programme with multiple boreholes planned from Pads 2 and 3. Analytical results from these boreholes, together with ongoing relogging and sampling work, will feed into the planned MRE update expected in Q1 2026.

In parallel with the drilling, the historical core relogging and sampling programme is ongoing, with additional drillcore and soil samples being analysed to strengthen the geological dataset. Results from re-analysis of historical tungsten samples confirmed an average 9.2% increase in tungsten grades, validating upside potential within the existing 2019 MRE, reported in accordance with the JORC Code (2012 Edition). Additional re-analysis of historical drillcore identified significant silver mineralisation associated with copper within the sheeted vein system, further enhancing Redmoor's economic and strategic value.

In support of the accelerated development programme at Redmoor, Strategic Minerals is investing in upgrading CRL's facilities and expanding its technical team. Since the initiation of the match grant funded activities, the team at Redmoor has increased to nine full time, permanent staff, with seven geologists, ensuring the smooth delivery of the exploration drilling programme and other exploration activities. To further support the effective and high-quality delivery of the programme, site upgrades include a significant improvement in core logging facilities and equipment available to the geological team, as well as new long term storage facilities for the existing exploration drill core with capacity for future programmes.

Southern Minerals Group LLC ("SMG")

Cobre magnetite stockpile, New Mexico, USA

Cobre continued to deliver a strong operational performance in H1 2025 with sales volumes of 28,467 tons (H1 2024: 31,327tons). With the benefit new and returning customers last year, and an extension of access to the Cobre magnetite operation's stockpile through to 31 March 2029, this revenue-generating subsidiary of the Company is in very good health. Revenues in H1 2025 were only marginally below H1 2024 as a result of a 10-day shutdown due to wildfires and we expect SMG to make this back up in the second half of this year.

Leigh Creek Copper Mine Pty Ltd ("LCCM")

Leigh Creek Copper Project

In April 2025, Strategic Minerals signed a non-binding Heads of Agreement granting an exclusive call option for A$100,000 to Axis Mining & Minerals Pty Ltd (subsequently novated to South Pacific Mineral Investments Pty Ltd trading as Cuprum Metals ("Cuprum")) to acquire 100% of LCCM. Under the terms of the option, Cuprum may acquire LCCM for an initial cash payment of A$1.9 million and the issue of shares in Cuprum equivalent to 19.9% ownership up to a maximum value of A$3 million. Cuprum intends to list on the Australian Securities Exchange. Additionally, Cuprum will pay a cash earn-out of A$4.0 million from future production. In the event of the share issuance to Strategic Minerals being less than A$3 million as a result of the 19.9% limit, the Earn-Out Consideration shall be adjusted to a higher level to reflect the difference in value from the A$3 million maximum limit.

If the option is exercised, this deal structure will enable Strategic Minerals to divest a non-core asset, direct further non-dilutive funds toward the development of Redmoor, and retain the upside of a potential future copper development through a substantial shareholding in Cuprum.   

Board Changes

In January 2025, Philip Haydn-Slater was appointed as an independent Non-Executive Director. Philip brings over 35 years of City experience, primarily in institutional sales and corporate broking. He co-founded HD Capital Partners and previously led Corporate Broking at WH Ireland in London, managing IPOs and secondary placings for resource-focused companies. Shortly after, in March 2025, Executive Director Peter Wale retired from the Board.

Post-Period end in August 2025, I transitioned from Non-Executive Chair to Executive Chair, reflecting my ongoing contributions to rationalising the Group and refocusing its strategy.

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 potential of the Redmoor Project, utilising sustainable cash flows from the Cobre operation to advance the project. We have in Redmoor the opportunity to develop a leading source of critical and strategic minerals to provide resilience to western world supply chains. Redmoor is already the highest-grade tungsten deposit in Europe and the second highest globally, with the potential to supply approximately 30% of Europe's tungsten needs before considering future upside from a potential upgrading of the MRE. The price of tungsten is soaring, reflecting ongoing shifts in the market, such as the closure of some previously subsidised Chinese operations and a growing emphasis on supply security for defence and high-technology applications. Having got the Cobre magnetite operation into sustainably good health last year, we are focused on accelerating the development of Redmoor to unlock its true value.
