Great Southern Copper, a London-listed exploration company, has confirmed a substantial extension of the Viuda Negra mineralised zone at its project in Chile. The updated geological model indicates the zone now extends over a significantly larger area than previously defined, with drilling results showing consistent copper mineralisation at depth and along strike.
The company stated that the expanded zone could host additional copper resources, though further drilling and feasibility studies are required to quantify the scale. The news comes as copper prices remain elevated on global markets, with the metal trading near $9,800 per tonne on the London Metal Exchange, supported by supply constraints and robust demand from the energy transition sector.
For UK investors, the development highlights the ongoing interest in copper-focused mining equities. Great Southern Copper's shares have seen increased trading volumes following the announcement, though the stock remains small-cap and carries higher risk. Analysts note that while early-stage exploration results are promising, investors should be mindful of the long lead times and capital requirements before production can begin.
The broader mining sector on the FTSE 100 and FTSE 250 has been mixed today, with the FTSE 100 down 0.3% to 8,215 points, while the FTSE 250 edged 0.1% higher to 20,542. Among mining stocks, Rio Tinto and Glencore were flat, while Antofagasta rose 0.8% on copper price optimism. The expansion at Viuda Negra adds to the pipeline of potential supply sources as the UK and other economies push for greater electrification.
Industry experts caution that exploration-stage companies like Great Southern Copper face significant hurdles, including permitting, financing, and infrastructure development. However, the discovery underscores the strategic importance of copper in achieving net-zero targets, which could support long-term demand for the metal and related equities.
