RC Drilling Begins at Great Southern Copper’s Victoria Prospect

Why It Matters

Successful drilling could substantially enlarge Great Southern Copper’s resource base, strengthening its position in a copper‑focused market and improving access to capital. It also validates the broader La Colorada lithocap as a fertile porphyry corridor, attracting further exploration investment.

Key Takeaways

• RC drilling targets high‑grade copper, gold, silver mineralisation.
• Surface samples returned up to 6.9% copper.
• Victoria lies 2.5 km from Artemisa North, another porphyry target.
• Program includes four holes and subsequent Artemis South testing.
• Geophysical surveys aim to map La Colorada lithocap.

Pulse Analysis

Great Southern Copper’s decision to commence reverse‑circulation drilling at the Victoria prospect underscores the growing strategic importance of Chile’s coastal metallogenic belt. The Especularita Project, positioned at low elevation with ready access to infrastructure, sits on the southern margin of the La Colorada lithocap—a geological feature increasingly recognized for hosting high‑grade porphyry systems. By targeting both breccia‑vein and disseminated mineralisation, the company aims to delineate a resource that could complement its nearby Artemisa North discovery, which already exhibits classic biotite‑chlorite‑magnetite alteration and sulphide mineralisation.

The initial surface chip assays from Victoria are striking, revealing copper grades of up to 6.9% alongside notable gold (1.85 g/t) and silver (84.8 g/t) concentrations. Such figures are competitive with some of the world’s premier copper projects and suggest the potential for a high‑value, multi‑metal deposit. The planned four‑hole RC program will probe beneath shallow gravel cover, a zone previously untested, and aims to confirm whether the high‑grade signatures extend at depth. If successful, the data could justify a transition from scout drilling to more intensive infill programs, accelerating the path toward a Preliminary Economic Assessment.

Looking ahead, Great Southern Copper’s roadmap includes shifting the drilling rig to the Artemisa South target and expanding geophysical efforts, such as an audio‑frequency magneto‑telluric survey and an induced polarisation campaign slated for mid‑2026. These initiatives will refine the structural model of the La Colorada lithocap, helping to pinpoint additional porphyry hotspots. For investors and industry observers, the Victoria drill results serve as a bellwether for the company’s ability to unlock new copper resources in a market where supply constraints are tightening and demand from renewable‑energy technologies is surging. The outcome will likely influence financing prospects and could position Great Southern Copper as a notable player in the next wave of Chilean copper development.
