• Underground mapping confirms a broader mineralised system supporting future larger-scale open pit resources
• New mineralised corridor defines near-term open-pit targets with potential to deliver supplementary feed
• High-grade sulphide system remains open at depth providing transformational upside

Cobre Limited (ASX: CBE) has announced significant resource growth potential at its Sierra Atacama copper operations in Chile. The company's ongoing work programmes are focused on converting the existing NI 43-101 resource into a JORC-compliant Mineral Resource Estimate (MRE), while simultaneously evaluating near-mine opportunities for resource growth and future operational expansion. Key highlights include the confirmation of a broader mineralised system through underground mapping, the identification of a new mineralised corridor that defines near-term open-pit targets, and the potential for a large underlying sulphide system. These findings support the company's strategy to build a larger, longer-life copper operation in Chile.

Cobre Ltd anticipates continued exploration and resource development at Sierra Atacama, with a focus on converting the existing resource into a JORC-compliant MRE and evaluating near-mine expansion opportunities.
