· In January the Company announced the appointment of Mr Philip Haydn-Slater as an independent Non-Executive Director.

Sales update: Cobre magnetite tailings operations

The Company posted sales volumes of 17,162 tonnes in the March quarter 2025, a 38% increase on the March quarter 2024 results, equating to US$1.18m of sales revenues, itself a 41% increase on the March 2024 quarter.

The Company continues to benefit from the return of Cobre's major client in the 2024 operational year and the in-country team have consistently delivered when scaling operations to meet demand.

Sales comparisons for quarterly and annual periods to 31 March 2025, along with associated volume details, are shown in the table below:

Cash Balances

As at 31 March 2025, the Company's cash balance was US$0.53m. This was due to another strong quarter of sales volumes at Cobre as the Company continues to rationalise the internal cost profile ready to focus on CRL and critical minerals exploration and development.

Cornwall Resources Limited

In February, the Company's 100% subsidiary CRL, announced initial success at Redmoor through a process of relogging and sampling of its existing diamond drill core.

Results identify new tungsten, copper and tin mineralisation within and external to the Sheeted-Vein-System (SVS), included:

· Tungsten trioxide grades of 0.33% WO3 over 1m from 393.5m and 0.30% WO3 over 1m from 440.95m, both in CRD025;

· Copper grades of 0.34% Cu over 4m from 384m in CRD022 and 0.42% over 1.25m from 326.9m in CRD024;

· Elevated tin concentrations up to 0.36% Sn over 1.3m from 270.7m in CRD027.

The results further validated the potential upside to the existing JORC (2012) compliant Redmoor Mineral Resource Estimate ("MRE") published on 14 February 2019.

Relogging continues and CRL has started to recruit more in-house geological specialists in order to accelerate the planned exploration work programme.

Commenting, Mark Burnett, Executive Director of Strategic Minerals, said:

"The Company continued to post strong operational and financial results in the first quarter of 2025 which will support the renewed focus on critical minerals exploration and development at the Redmoor Tungsten-Tin-Copper Project in Cornwall, UK. I would like to thank the whole team for their dedication throughout this transition period and look forward to delivering value for shareholders in 2025."

1 Equivalent metal calculation notes; Sn(Eq)% = Sn% x 1 + WO3% x 1.43 + Cu% x 0.40. WO3(EQ)% = Sn% x 0.7 + WO3 + Cu% x 0.28. Commodity price assumptions: WO3 US$ 33,000/t, Sn US$ 22,000/t, Cu US$ 7,000/t. Recovery assumptions: total WO3 recovery 72%, total Sn recovery 68% & total Cu recovery 85% and payability assumptions of 81%, 90% and 90% respectively
