LONDON - Great Southern Copper (NYSE:SCCO) plc (LSE: GSCU) has commenced its Phase I diamond drilling program at the Cerro Negro prospect in Chile, targeting high-grade copper (Cu), silver (Ag), and gold (Au) mineralization at the Mostaza mine. The company aims to confirm and extend the known mineralized zone both to depth and along-strike.
The initial drilling plan at Mostaza includes up to 5 to 10 diamond drill holes, covering a total of 500 to 1,000 meters. This follows historical non-JORC estimates from 1981, which reported significant sulfide resources with notable grades of Cu, Ag, and Au.
The drilling at Mostaza is designed to verify historical drill results and explore the potential for expanding the mineralization. The first hole, CNG25-DD001, is underway and is expected to test both the historical grades and the extent of the mineralization.
Sam Garrett, CEO of Great Southern Copper, expressed optimism about the drilling program, stating that historical drilling had not fully tested the mineralization, which appears open in all directions. The company also completed a scout RC drilling program at the Viuda prospect before Christmas, identifying porphyry-style alteration in all holes. Assay results from this program are pending.
Cerro Negro is located within the Especularita project, strategically situated near national infrastructure and within a metallogenic belt known for significant copper and gold deposits. The Mostaza mine is part of this project, which has shown potential for an extensive mineralized system.
The company cautions that historical resource estimates are non-JORC compliant and should only be considered for historical context. Great Southern Copper has not independently verified the historical drilling results but plans to use the current drilling program to establish a more definitive understanding of the mineralization at Cerro Negro.
This exploration activity is based on a press release statement from Great Southern Copper plc.
