⚒️ Southern Hemisphere Mining Limited reports diamond drilling has commenced to test the newly discovered Ferro South zone and deeper copper targets at the Company’s Llahuin Copper-Gold-Moly Project in Chile.
Southern Hemisphere Mining Chairman Mark Stowell commented:
“Southern Hemisphere Mining is working in Chile to discover a serious copper-gold-moly mine at Llahuin to supply copper metal into predicted future supply shortages. Our drilling is getting closer to the game changing drill hole or two as we vector towards the anticipated copper-gold feeder zone(s).”
- Diamond drilling is underway at Ferro South following the Company’s recently reported copper discovery
- The initial program is planned for approximately 2,000 metres over ten weeks, with scope to extend drilling in response to geological observations and results
- Initial holes are designed to test the extent and continuity of mineralisation and further investigate potential feeder zones within the broader Llahuin system
- Copper isotope studies have identified an additional isotopic vector that may assist in targeting deeper copper mineralisation within the broader Cerro-Ferro system
- Initial assay results are expected towards the end of November 2026, subject to laboratory turnaround times

The commencement of drilling follows Southern Hemisphere’s announcement on 10 September 2026 outlining a follow-up drilling program at Ferro South.
The Company plans to drill initial holes to approximately 300 metres downhole, with selected holes potentially extended to approximately 500 metres where geological observations in the drill core warrant further testing.
A copper isotope study undertaken by VectOres has identified isotopic vectors interpreted to indicate the potential for a deeper mineralised source within the broader Cerro-Ferro system.
The current diamond drilling program will test these targets and provide further information on the geometry, continuity and potential depth extent of the mineralised system.
Copper isotope analysis is an emerging exploration technique that examines variations in naturally occurring copper isotopes, including δCu-65 and δCu-63. These variations may provide exploration vectors toward the source of copper-bearing hydrothermal fluids and assist geologists in refining targets within porphyry copper systems.

Drill core will be geologically logged, sampled and submitted for laboratory analysis. The Company expects initial assays results towards the end of November 2026, subject to laboratory turnaround times, and will report material results as they become available.
