Great Southern Copper plc, a company focused on copper-gold exploration in Chile, has commenced reconnaissance diamond drilling at its San Lorenzo project in Chile.
The proposed programme will target four individual prospect zones across the project with a total of 2000 – 2500 m of diamond drilling (10 – 15 holes each at 100 – 300 m depth). The drilling will test multiple styles of copper-gold (Cu-Au) mineralisation and will enhance the geological understanding of the mineralised system at San Lorenzo and provide vectors for further exploration including follow-up drilling programmes.
Anomalous copper-gold hosted in sheeted vein swarms cutting granodiorite will be tested at both the Central and Chinchillon prospect zones. The sheeted vein mineralisation shows similarities to alkalic-style porphyry Cu-Au mineralisation.
Outcropping copper and gold mineralisation hosted within the upper cuppola zone of monzonite intrusives (exhibiting unidirectional solidification textures or UST) will be tested with shallow drilling (100 – 200 m) at both the Las Hermanas prospect zone as well as the Cerro Blanco prospect zone.
Sam Garrett, CEO of Great Southern Copper, said: “We are excited to be starting the company’s first drilling campaign at San Lorenzo. The shallow drilling programme targeting surface geology and geochemical anomalies at multiple prospects will significantly enhance our understanding of the broader mineralised system at San Lorenzo. The alteration and mineralised system at San Lorenzo is very large and this programme will be critical to further refine our targets for on-going exploration.”
Especularita Project
As announced in April 2022, systematic geological mapping and rock chip sampling commenced at GSC’s Especularita project in Chile. The extensive concession area at Especularita encompasses numerous styles of mineralisation related to Cretaceous intrusives and the overlying volcanics, ranging from gold-rich vein swarms and copper-bearing breccia pipes in the intrusives, to advanced argillic lithocap in the volcanics. This phase of work will identify targets for detailed follow-up exploration such as trenching, geophysics and reconnaissance drilling.
