en.Wedoany.com Reported - Great Southern Copper has initiated reverse circulation (RC) drilling at the Victoria porphyry copper target within the Especularita project in Chile, aiming to evaluate high-grade breccia veins and disseminated copper mineralization. The company plans to drill four holes to test vein and disseminated mineralization identified in outcrops, as well as areas beneath artisanal and small-scale mining operations. Previous surface rock chip samples collected from the Victoria prospect show copper grades of up to 6.9%, gold grades of up to 1.85 g/t, and silver grades of up to 84.8 g/t.

The Victoria prospect is located approximately 2.5 km southeast of the Artemisa North target, along the southern margin of the La Colorada sill. The company stated that the target remains largely unexplored beneath shallow gravel and scree cover, with mineralization believed to be open along a significant footprint. In related developments, drilling at the nearby Artemisa North prospect has been completed, with a total of five holes drilled for 796 meters. Each hole encountered biotite-chlorite-magnetite alteration accompanied by varying degrees of sulfide mineralization, with the alteration type and intensity confirming the presence of a porphyry copper system in the area. All samples from four holes have been sent to ALS Laboratories in Santiago for analysis. Great Southern Copper holds 100% ownership of both the Victoria and Artemisa North targets. The company's CEO, Sam Garrett, stated that Victoria is the third of four targets to be tested through reconnaissance RC drilling in the current porphyry exploration program, which focuses on targets along the western and southern margins of the La Colorada sill that exhibit typical geological, geochemical, and spectral characteristics of porphyry copper systems. The Especularita project is located in a low-altitude area of the Cretaceous Coastal Metallogenic Belt, facilitating access to infrastructure and mining services. Following the completion of reconnaissance RC drilling at Victoria, the company plans to move the rig to the Artemisa South area for similar testing. Additionally, an audio-magnetotelluric geophysical survey is underway at the La Colorada sill, with plans to expand the Cerro Negro induced polarization survey, with related work scheduled to commence in June 2026.
