Great Southern Copper Extends High-Grade Copper-Silver System at Cerro Negro and Ramps Up 2026 Drilling Plans

Great Southern Copper PLC ( (GB:GSCU) ) has shared an update.

Great Southern Copper has completed its largest and most advanced drilling campaign to date at the Cerro Negro prospect within its Especularita project in Chile, with Phase III diamond and reverse circulation drilling extending the high-grade copper-silver system at the Mostaza area and identifying potential stacked high-grade Cu-Ag lenses as well as a new silver-lead-zinc lens. While assays for a number of holes are still pending, early Phase III results show notable copper and silver grades and have confirmed mineralisation along the broader Mostaza Fault Zone, underpinning the company’s plans for further drilling at Cerro Negro and additional exploration at the Viuda and Colorada targets, where GSC is pursuing what it describes as district-scale porphyry copper-gold opportunities. The company is now advancing drill planning for 2026, including follow-up programmes at Cerro Negro and Viuda and first-pass drilling at Colorada, as it seeks to capitalise on strong copper, gold and silver prices and realise what management and an independent research note both characterise as substantial upside potential across its Chilean exploration portfolio.

The most recent analyst rating on (GB:GSCU) stock is a Hold with a £3.50 price target. To see the full list of analyst forecasts on Great Southern Copper PLC stock, see the GB:GSCU Stock Forecast page.

Spark’s Take on GB:GSCU Stock

According to Spark, TipRanks’ AI Analyst, GB:GSCU is a Neutral.

The score is held down primarily by weak financial performance (pre-revenue, widening losses, and ongoing cash burn). Technicals are supportive with price above key moving averages and a positive MACD, but overbought RSI/Stoch temper the outlook. Corporate events are a modest positive due to active exploration progress and fresh funding, while valuation cannot be assessed from the provided P/E and dividend data.
