Great Southern Copper Reports High-Grade Copper Results from Cerro Negro Project in Chile
STRATEGIC MINERALS
Great Southern Copper PLC announced further high-grade copper results from the Mostaza discovery in its Cerro Negro project, Chile. The latest drill hole returned grades of up to 6.55% copper and strong silver values, confirming mineralization extends 400 meters south from earlier drilling.
This reinforces the geological interpretation that the same style of mineralization continues along the Mostaza fault trend. The Phase 4 drilling program aims to explore further south and conduct infill drilling to potentially connect mineralized zones over a 400 to 600 meter trend. Overall, the exploration program indicates positive progress.
