Great Southern Copper Extends High-Grade Mostaza Discovery in Chilean Drilling

An announcement from Great Southern Copper PLC ( (GB:GSCU) ) is now available.

Great Southern Copper reported strong partial assay results from step-out diamond hole CNG25-DD042 at the Cerro Negro prospect, confirming an extension of the Mostaza copper-silver system some 300 to 400 metres south of the historic mine. The hole intersected multiple mineralised zones, including 21.8 metres at 1.04% copper and 52.26 g/t silver with a 1.6-metre interval grading 6.55% copper and 319.75 g/t silver, alongside lead-zinc-silver rich breccias that support a complex, stacked deposit model.

The new intercepts suggest mineralisation is coalescing and thickening to the south, extend the defined Cu-Ag trend to more than 400 metres along strike and remain open at depth and under shallow cover. These results are shaping a fully funded Phase IV drilling campaign focused on in-fill drilling to potentially link Lens 2 mineralisation between the Mostaza mine and recent holes, as well as further step-out drilling to test the broader two-kilometre Mostaza Fault Zone, underlining the project’s growth potential for investors and other stakeholders.

The most recent analyst rating on (GB:GSCU) stock is a Sell with a £2.00 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 primarily driven by weak financial performance (pre-revenue, widening losses, and sustained negative free cash flow), partially offset by the absence of reported debt. Technical signals are mixed-to-weak, with price below the 20-day average and low momentum indicators, while valuation impact is limited due to missing P/E and dividend yield.
