Sign 25-Year Dudnance Mineral Lease

On June 25, 2026, Cornish Metals announced the signing and completion of a new "Dudnance Lease" mineral lease in the South Crofty tin mine project area in Cornwall, UK. The lease has a term of 25 years and was agreed with the Preston family, who hold 50% of the mineral rights in the area; the company previously held the remaining 50%. This signing further consolidates the company's position within the South Crofty mining license area, reduces ownership-related risks, and enhances certainty for long-term project development and operations.

Integrated Rights Support Long-Term Project Development

Located within the historical mining footprint, this right represents another key step in the company's strategy to integrate mining rights following the Pendarves and Vyvyan estates. The move aims to support the advancement of the South Crofty project toward construction and production phases, utilizing existing underground infrastructure and high-grade tin resource potential. Given this is a legal procedure regarding ownership rights, it involves no specific changes to production or capital expenditure, having limited impact on short-term supply, primarily benefiting long-term project compliance and financing stability.
