GSC identifies new high-grade exploration target at Chile prospect

Great Southern Copper plc, the company focused on copper-gold-lithium exploration in Chile, has announced that results from exploration mapping and sampling at its Viuda prospect confirm the potential for a new untested porphyry Cu-Au system.
Highlights
- High-grade copper-gold-silver mineralisation associated with stockwork and vein breccia.
- Rock chip samples from artisanal workings range up to 3.5% Cu, 13.85 g/t Au and 56.6 g/t Ag.
- 10 samples (18%) return assay grades >1.0% Cu.
- Mapping demonstrates typical large-scale porphyry copper-type geology and alteration.
- Scale of system similar to known porphyry Cu-Au deposits, such as Bajo de Alumbrera.
- No evidence of historical exploration drilling.
- Excellent prospect access with potential to fast-track drill testing.
- Coastal metallogenic belt location with excellent access to infrastructure.
The Viuda prospect was acquired by the company earlier this year as part of the Artemisa Option Agreement which now forms the broader Especularita Project located in the coastal metallogenic belt of Chile.
The prospect comprises 16 km2 of concessions centred upon a prominent hill of resistive siliceous rock surrounded by a large bowl-shaped depression, or ‘bajo’, of clay-altered granodiorite – a geological setting typical of many porphyry copper and copper-gold systems. Recent exploration work by GSC includes prospect-scale mapping and sampling with 55 rock chip grab samples collected and assayed.
Sam Garrett, Chief Executive Officer of Great Southern Copper, said: “The discovery of additional porphyry style Cu-Au-Ag alteration and mineralisation at Viuda is very exciting and further emphasises the potential of the Especularita Project to host multiple porphyry copper centres.
“While we prepare for drilling at Mostaza, it is encouraging to know that our targeted exploration programme is resulting in more grass-roots prospects being elevated to drill-ready status, thus providing the Company with an enviable pipeline of drill-target opportunities.”

Decarbonising mining is challenging. While electric and hydrogen solutions show promise, they are still in development and not yet reliable for heavy equipment in demanding environments due to tough conditions and varying infrastructure across regions.
