Great Southern Copper, a company focused on copper-gold exploration in Chile, has announced results from its mapping and sampling activity at the Victoria prospect, one of several prospects currently under evaluation at the Especularita Project.
Highlights:
- Assay grades in rock chips up to 6.9% Cu and 1.85g/t Au from outcropping vein-breccias.
- 25% of outcrop samples assay over 1% Cu and 50% of samples assay over 0.3% Cu.
- Multiple outcropping vein breccias have been mapped over a 1000 x 600 m area.
- Potential for additional vein-breccia structures under shallow cover.
- No previous drilling in the target area.
- Exploration to define drill targets underway.
Victoria is one of several prospects currently under investigation within GSC’s Especularita Project. The prospect comprises a field dominated by copper-mineralised float (surface boulders) located adjacent to the southern margin of the Colorada advanced argillic lithocap. The mineralised float is characteristic of high-grade, structurally-controlled vein breccias.
A trial programme of float sampling indicates that the vein-breccia material is highly anomalous in copper and gold with assays grading up to 2.1% Cu and 4.29g/t Au (as reported in the Company’s release on 27 March, 2023). Subsequent mapping to locate the potential source of the high-grade copper mineralisation has identified outcrops of structurally-controlled vein-breccia in multiple locations over an area of approximately 1000 x 600 m. In several locations the mineralized structures are identified by the presence of artisanal mine workings.
Sam Garrett, Chief Executive Officer of Great Southern Copper, said: “The company is very pleased to report these results from our follow-up mapping and sampling work at Victoria. The high-grade copper identified in outcrops and artisanal mine dumps strongly validates these mineralised structures as an exciting exploration target for GSC. Follow-up exploration efforts will now be designed with the aim of defining exploration drill targets for Victoria. We now have exploration teams working on three prospects within our Especularita Project area - Victoria, Teresita and Aurelia – as well as a reconnaissance team collecting stream sediment samples across the entire project footprint. Our 100% Chilean crews are working very hard and delivering exciting results and I thank them for their efforts. Their results continue to support our understanding that Especularita is part of a district-scale mineralised system demonstrating potential for the full spectrum of both porphyry and intrusive-related copper-gold type deposits.”
