Southern Hemisphere Mining Limited reports excellent results from its 100% owned Llahuin Copper-Gold-Moly Project in Central Chile.
Llahuin’s current endowment is 680,000t CuEq and expanding. A soil sampling program has been successful in identifying a large copper and gold target. A substantial 1.9km long copper in soil anomaly (+800ppm Cu) has been identified along the Cerro-Ferro trend interpreted as one large system, with an indicated width of 200m to 300m with a peak value of 1.4% Cu. Rockchip sampling of some of the numerous old workings in the target area so far has produced a best result of 9.13g/t gold.

- The 100% owned Llahuin Copper/Gold/Moly deposits host over 680kt CuEq in Central Chile.
- A substantial 1.9km long copper in soil anomaly (+800ppm Cu) has been identified along the CerroFerro trend, interpreted as one large system, with indicated width of 200m to 300m with a peak value of 1.4% Cu.
- Rockchip sampling of some of the numerous old workings in the target area so far has produced a best result of 9.13g/t Gold.

These highly prospective results demonstrate potential for a massive increase in open pit tonnage and grade in these under-explored areas of Llahuin.
The work we are doing at Llahuin is setting Southern Hemisphere, and this project, up as one of the emerging solutions for the looming global demand/supply gap for copper in the battery minerals sector. Llahuin is well advanced with over 60km of drilling to date, and the new exploration team is showing considerable success with new conceptual ideas backed up by on ground results.
‘Facing the looming supply gap, copper prices will inevitably rise, experts told S&P Global Commodity Insights. In turn, higher copper prices will play a central role in spurring new mine supply, though it remains to be seen if that can happen quickly enough or to the extent demand will require.’
The soil sampling data clearly shows that the Cerro and Ferro deposits are potentially linked with a robust 800ppm Cu in soil anomaly connecting them and extending further south of the Ferro deposit, with a peak value of 1.4% copper in soil.
The soil program targeted areas that were not previously drilled so approximately 850m of the 1.9km strike has not been drill tested at the Cerro-Ferro zone. (Figure 2). The 1.9km long NS orientated advanced argillic alteration zone is coincident with the positive soil sampling results (Figure 3). Soils were completed in areas of drilling to demonstrate continuity and show scope for significant open pit type expansion of both deposits which have only been lightly drilled to date.

Details of the work are as follows:
Soils were collected on a 200m line spacing with 50m spacing between samples. Infill sampling is typically 100m spaced sample lines and 25m sample spacing.
The soils are analysed by an Olympus Vanta “M-series” Pxrf. A comparison with 210 Laboratory Copper analyses showed excellent agreement with an R2 value of 0.99. An appropriate standard and blank are analysed for each batch of approximately 20 samples and demonstrates the instrument is reading within acceptable tolerances.
Anomalous soil sample results are field checked that residual material was sampled by the Exploration Manager or the Senior Geologist on site.
NEXT PROGRAMS AT LLAHUIN
Exploration work continues to scope out the scale potential and new copper/gold targets at Llahuin. Further results will be reported in due course.
Chairman Mark Stowell commented:
“We have grown in confidence that the extensive relogging and reinterpretation of previously unidentified breccia mineralisation in the system, combined with this recent work, is indicating large upgrade potential for near-surface open pit mineralisation at Cerro-Ferro, positioning the Company well for further success”.
