Southern Hemisphere Mining Limited reports the Quarterly Activity Report for the period ended 30 June 2023.



  • Llahuin Copper-Gold-Moly Porphyry Project 100%

During the quarter under review, the Company continued its soil, rock chip sampling, mapping programs and its extensive relogging of historical drill holes to understand newly-discovered veins hosting high-grade mineralisation occurring in swarms within the porphyry breccia.

The team on site also completed over 4,000 pulp composites which have been multi-element analysed by in-house Pxrf to assist with understanding the multi-element signature of the deposit.

The relogging and Pxrf work will assist with the new geological interpretation later this year. This understanding is a vital part of refining the highly anticipated drill program scheduled for the 4th quarter this year.

On 19 April 2023, the Company reported that the geological mapping of areas previously unexplored within the project area continued and identified additional mineralised veins in areas outside known resources in the project area.

The Company also panned gold in five samples taken from a 500m stretch north of the resource zone at the 1.9km-long Cerro Ferro porphyry-hosted geochemistry target. From the newly-discovered outcropping quartz veins a best result of 18.65g/t gold, with another sample just 4m away returned 7.56g/t gold.

Several high-grade copper veins were also found west of Ferrocarril porphyry deposit returning results of up to 7.28% copper.

  • Los Pumas Battery Metals Manganese Project 100%

On 3 May 2023, the Company reported a substantial JORC mineral resource upgrade for its wholly owned Los Pumas Battery Metals Manganese Project in northern Chile to 30.26 million tonnes of ore, including 23.3 million tonnes in the indicated category.

The resource upgrade now concludes the exploration stage of this long-life battery metals manganese project and moves it to the scoping and metallurgical study phase.

The advance also marks a milestone in the Company’s plans to provide high-quality resources for the production of High-Purity Manganese at site.
