Great Southern Copper (GSCU ) booked a loss of £2.5 million in the year to March 2026.
The company closed out the period with just under £1.2 million in the bank, following a £2.5 million fundraising in November 2025.
Much was achieved at the Especularita copper project during the period, including drilling, sampling, mapping, and modelling.
"This has been a transformational year for Great Southern Copper, in which we have advanced our two-pronged exploration strategy across the Especularita project with real momentum,” said Sam Garrett, chief executive of Great Southern Copper.
"At Mostaza, three successive drilling campaigns have confirmed a high-grade copper-silver discovery of exceptional quality, and our Phase III programme, the largest and most advanced we have undertaken, extended the high-grade Lens 2 mineralisation both along strike and to depth while revealing a series of stacked lenses within a broader system that we believe points to a genuinely scalable deposit. Alongside this, we have opened up the district-scale porphyry potential of the wider project. We confirmed the discovery of a near-surface porphyry gold system at Viuda, the first of its kind recognised in Chile's coastal belt, expanded our ground over the La Colorada lithocap, and completed our first scout drilling programme across four porphyry copper targets at Piedras Blancas, Artemisa North, Victoria and Artemisa South."

Very good progress from Great Southern over the past year, with plenty more to come. The plan now is to advance Mostaza towards resource definition through Phase IV drilling, while continuing to test the district-scale opportunity across Especularita. The copper price has been strong too in recent months, providing a significant tailwind. Watch this space for further news.
