In this exclusive interview, StockBox speaks with Sam Garrett, CEO of Great Southern Copper (LSE: GSCU), about the final results from the Phase 2 drilling program at the Cerro Negro project in Chile.
The focus is on the Mostaza copper-silver deposit, where all holes have intersected mineralisation — confirming continuity and high-grade potential at Lens 2.
- High-grade copper-silver mineralisation confirmed at Lens 2, with all holes intersecting mineralisation.
- Phase 3 drilling to target deeper zones in Lenses 3–5, chasing a potentially 400m+ deposit.
- Strong economic potential with surface access, high grades, and proximity to infrastructure.
Sam Garrett, Chief Executive Officer of Great Southern Copper, said: “These high-grade copper-silver results continue to build our understanding of the geometry and continuity of the mineralisation at Mostaza. Although holes DD021 to DD023 did not encounter high-grade mineralisation, they provide valuable geological information, helping to refine our model.
“We are also excited to report the first mineralised intercept from Lens 1 in DD025 – our first ever drill intersection into Lens 1, which provides encouragement for follow-up drilling. These results represent an important step in our broader campaign to define a potentially significant cluster of mineralised lenses at Cerro Negro.
“Drill planning is well advanced for our Phase III programme, which we hope to commence in late August, subject to drill rig availability. This is an exciting time for GSC as we begin the next step to attempt to explore the growth potential of this high-grade asset.”
