Great Southern Copper publish results from Scout Drilling Programme

Highlights:

• Mineralisation hosted in monzonite intrusives with grades up to 1.65% Cu and 3.62 g/t Au.
• Elevated Cu grades (> 300-500ppm Cu) within drill-tested monzonitic intrusions indicate they are an important control to the intrusive-related type Cu-Au mineralisation.
• Numerous unidirectional solidification textures (“UST’s”) occurrences are a positive indicator of the presence of mineralised intrusions within the San Lorenzo district
• Broad zones (>30-100m) of anomalous Cu-Au-Mo hosted in sheeted fracture systems within granodiorite confirm the potential of these systems to host large scale intrusive-related style Cu-Au mineralisation.
• Mineralised sheeted fracture-veins overprinting the monzonite intrusives and UST occurrences provide evidence for a further causative mineralising intrusive at depth.

The results confirm that the monzonite intrusives are an important control on Cu-Au mineralisation at Cerro Chinchillon and they provide a significant vector for the next phase of the Company’s exploration. The Company will exhaustively review and evaluate the scout drilling data over the coming months with the aim of designing the next phase of exploration programmes focussing on an economic Cu-Au deposit.

Sam Garrett, Chief Executive Officer of Great Southern Copper, said: “The assay results from the scout drilling programme at the Cerro Chinchillon prospect area are highly encouraging and demonstrate that GSC has discovered a large intrusive-related Cu-Au mineralised system. Intrusive-related gold-copper deposits have the potential to be very large and we have only scratched the surface in terms of the volume of monzonite bodies to test at San Lorenzo, most of which exhibit evidence of mineralisation to some degree. A significant volume of copper has been introduced to the system at San Lorenzo and so the task ahead of us now is to focus toward where the source and economic traps are. The Chinchillon-Central-Cerro Blanco prospects targeted by the scout drilling programme cover a broad area of some 16-20 km², however, this only comprises a small portion of the total San Lorenzo project. Our ongoing regional exploration efforts are identifying new targets which will require further prospect-scale exploration.”
