Southern Hemisphere Mining Limited reports high-grade rock chips up to 7.28% Cu, 18.65g/t Au and 55g/t Ag as the Company continues to expand the mineralised footprint of the Llahuin Copper/Gold/Moly Project in Chile.


  • A rock chip sampling and mapping program started in 2022 and continuing in 2023 has identified further high-grade veins in the Llahuin Project area 500m North of the CerroFerro 1.9km Geochem target
  • Gold panned in samples
  • Vein swarms host the higher-grade mineralisation within the porphyry breccia, so understanding the vein systems is important in refining drill hole locations
  • Several high-grade veins west of Ferrocarril were sampled up to 7.28% Cu
  • An outcropping vein 500m north of Cerro de Oro 18.65g/t Au, 0.1% Cu and 1g/t Ag and 4m along strike with 7.56g/t Au, 0.09% Cu and 2g/t Ag

German Version of the ASX Announcement

Figure 1. Location Map of Llahuin Project – Chile

Southern Hemisphere Mining Limited reports that the geological mapping of areas previously unexplored within the project area continues and has identified additional mineralised veins in areas outside known resources in the project area.

All rock chip assays are presented in Table 1 below with better grades highlighted in red.

Figure 3. Location of high-grade gold samples north of Cerro De Oro resource

The high-grade gold rock chips are from a vein 500m north of Cerro de Oro which was revisited and 5 samples were collected and crushed and panned for gold at site with all five showing visible gold tails in the pan.

One sample about half a fist size produced a 2.5cm long gold tail (Figure 5) with further methodical sampling planned to test the vein in the historical adit.

Several north trending and east dipping veins were sampled west of Ferrocarril with high grade copper with the location shown in Figure 4 below.

The Company regularly submits standards and blanks with each laboratory submission as part of the on-going QAQC program. No issues with the ALS laboratory data have been observed for the rock chip sampling program.

The mapping and sampling program is continuing in 2023 to add to the understanding of the veins and vein swarms to assist in refining drill locations . Further exploration work continues to expand the target opportunities for copper/gold/moly/silver resource expansion within the concessions.
