Southern Hemisphere Mining Limited reports that the geological mapping of areas previously un-explored within the project area included 254 rockchips collected during the 2022 mapping program at the Company’s Llahuin Copper Gold Project in Chile.

The rockchip sampling program at Llahuin has identified several veins in areas outside known resources in the project area.

Significant results are presented below (Table 1) and demonstrate very high-grade copper ±- gold ± silver veins occur in the project area.

  • A rock chip sampling and mapping program started in 2022 has identified high-grade veins in the Llahuin Project area.
  • The best results include 22LHR000184 with 4.12% Cu 0.36g/t Au and 1,495g/t Ag from an outcropping vein at Cerro de Oro and 22LHR000183 located 20m along strike with 2.74% Cu, 0.58g/t Au and 1,045g/t Ag.
  • Samples 22LHR000105 and 106 sampled a North-South striking vein over a 90m strike (where exposed) and returned values of 16.6% Cu, 0.94g/t Au and 1g/t Ag and 16.3% Cu, 1.13g/t Au and 4g/t Ag respectively, located 1km North of Cerro de Oro.

Three target areas have been defined, one at Cerro de Oro, a second 1km North of Cerro de Oro and a third North of the Central Porphyry insets A, B and C above.

The NE striking vein North of the Cerro de Oro deposit contains high-grade copper and silver outlined by samples 22LHR000183-184 which contain visible azurite and chalcocite. The area will require additional work to determine the strike extent of this vein system. An additional two copper-bearing veins were identified to the NE of this with sample 22LHR000214 assaying 1.66% Cu, 4.53g/t Au and 3g/t Ag.

The vein system North of the Central Porphyry contains several thin <2m wide, higher grade copper and gold veins which strike NNE to NE.

The copper values ranged from 0.1% to 17.5% copper and gold values from 0.01 to 6g/t gold in an NNE trending vein system which requires further work.

Very high-grade Cu-bearing veins were sampled to the west of the Cerro de Oro deposit with samples 22LHR000105 and 106 testing a North-South striking vein over a 90m strike (where exposed) and returned values of 16.6% Cu, 094g/t Au and 1g/t Ag and 16.3% Cu, 1.13g/t Au and 4g/t Ag respectively.

The sampling program has continued into 2023 to better define veins suitable for drill testing.

Further exploration work continues to expand the target opportunities for copper/gold/silver resource expansion.
