Cornish Metals' Critical Minerals Focus in Cornwall Underpins Investor Interest

Cornish Metals Plc operates in Cornwall, southwest England, targeting deposits of tin and copper — minerals classified as critical to the UK's industrial and clean energy supply chains. The company's projects include the United Downs and South Crofty assets, which sit within one of Europe's historically significant hard-rock mining regions. As the UK Government has sought to reduce reliance on overseas sources of critical raw materials, domestically focused mining companies such as Cornish Metals have attracted growing attention from investors. This strategic backdrop may be a factor informing Leonidsport B.V.'s decision to build a material position in the company.

The filing provides no further detail regarding Leonidsport B.V.'s investment rationale, intentions, or any agreed relationship with the company's board or management.
