Southern Hemisphere Mining Limited reports that a second infill program has confirmed and added gold to the new Southern Porphyry target in the South of the Llahuin Copper-Gold-Moly Project area (Figure 3) as an oblong copper/gold in soil anomaly with a footprint similar to the Central Porphyry and shows a robust +500ppm copper in soil contour with a peak value of 0.22% (2,232ppm) copper in soil.

The core 1,000ppm copper contour extends for approximately 200m in a NNW direction.

  • The 100% owned Llahuin Copper-Gold-Moly deposits host over 680kt CuEq in Central Chile.
  • Infill soil sampling has confirmed the Southern Porphyry Copper in soil anomaly in the Southern part of the Llahuin Project, previously reported, with a new peak value of 0.22% Copper and 0.24g/t Gold, so now the Southern Porphyry is a Copper/Gold anomaly.
  • The Southern Porphyry anomaly sits within a large circular magnetic feature – a classic porphyry style magnetic target.

The Southern Porphyry gold assays show a robust, coincident +40ppb gold in soil anomaly associated with the copper in soil anomaly with a peak value of 240ppb gold.

As previously reported the anomaly is spatially associated with a large circular magnetic high which is interpreted to be a porphyry signature.

Details of the work are as follows:

  • Infill soil 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 demonstrate the instrument is reading within acceptable tolerances.
  • The Company geologists are currently completing geological/structural mapping in the area of the Copper in soil anomaly to better understand the area.
  • Further exploration work continues to target new opportunities for copper/gold resource expansion.
