The latest update is out from Great Southern Copper PLC ( (GB:GSCU) ).
Great Southern Copper has reported strong partial assay results from step-out diamond drill hole DD042 at the Cerro Negro prospect in Chile, confirming a southern extension of the Mostaza copper-silver system. The hole, drilled about 300m south of historic workings, intersected multiple mineralised zones including 21.8m at 1.04% copper and 52.26g/t silver, with a high-grade interval of 1.6m at 6.55% copper and 319.75g/t silver.
The new intercepts extend the Mostaza mineralised trend to more than 400m of strike, with mineralisation remaining open to the south and at depth and showing a complex, multiphase stacked geometry with additional lead-zinc-silver zones. These results, received amid longer assay turnaround times in Chile, are driving the design of a fully funded Phase IV drilling campaign focused on in-fill and step-out drilling to potentially link and expand the Lens 2 mineralisation and further test the broader Cerro Negro system.
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.
