Mark Burnett, Executive Director of Strategic Minerals, commented:

“2025 was a transformational year for Strategic Minerals. We successfully restructured and reorganised the Company, positioning it to deliver increased near-term revenue from Cobre and long-term value creation from the Redmoor Tungsten-Tin-Copper Project. We are utilising sustainable cash flows from Cobre to unlock the full potential of Redmoor with a clear opportunity to develop it and the surrounding area into a world leading source of tungsten, tin and copper to provide resilience to western world supply chains. The Redmoor drill programme has gone exceptionally well so far, and we anticipate further resource growth and additional efficiencies for future infill drilling as part of a pre-feasibility programme.”
