Great Southern Copper CEO on high-grade copper at Mostaza discovery

Great Southern Copper PLC (LSE:GSCU, FRA:E9E) CEO Sam Garrett talked with Proactive's Stephen Gunnion about the company’s latest drilling results at the Mostaza discovery within its Cerro Negro project in Chile. Garrett discussed a new drill hole intersecting copper grades of up to 6.55%, alongside strong silver values, highlighting the continued success of the company’s exploration program. Garrett said the result confirms a significant step-out from earlier drilling and supports the company’s geological model along the Mostaza fault trend. The hole was drilled roughly 400 metres south of previous drilling, demonstrating that the same style of mineralisation continues beyond the historic Mostaza pit. The drilling also indicates that mineralisation extends over a growing strike length. Garrett explained that the results show consistent geological architecture between new drill holes and earlier intersections beneath the Mostaza pit, strengthening the company’s confidence that multiple zones could ultimately be linked. “We’re seeing the same architecture in the new holes for 300 metres to the south of the Mostaza pit, but now mineralisation has extended over 400 metres in strike length,” Garrett said. The latest drilling has also revealed stacked zones containing copper, silver, lead and zinc mineralisation. According to Garrett, this confirms earlier geological interpretations and suggests a consistent mineralised system, although the structure has been affected by faulting and diking. Looking ahead, the company plans to continue drilling through its fully funded Phase 4 program, targeting extensions of mineralisation further south under shallow cover while also completing infill drilling between existing holes and the Mostaza pit.
