- Further upside is evident for exploration of Manganese feeder zones within the orebody which outcrop at surface and have had little or no prior exploration
- The location of the Los Pumas Manganese Project is highly advantageous from a carbon footprint perspective, close to the Chapiquina Hydroelectric Power Plant and the port city of Arica in Northern Chile
- This JORC Resource advances the studies towards production of High Purity Manganese Sulphate Monohydrate (“HPMSM”) at site to supply the North American, European Union and global EV markets
Southern Hemisphere Mining Limited (“Southern Hemisphere” or “the Company”) (ASX: SUH, FWB: NK4) reports a substantial JORC mineral resource upgrade for its wholly owned Los Pumas Manganese Project in Chile to 30.26 million tonnes of ore, including 23.3 million tonnes in the indicated category. This now concludes the exploration stage of this long-life battery metal manganese project and moves it to the scoping and metallurgical study phase.
This advance marks a major milestone in our plans to provide high-quality resources for the production of High-Purity Manganese at site in Northern Chile to supply the North American and European Union Electric Vehicle (“EV”) markets.

Los Pumas Battery Metal Manganese Project – 100%
Figure 1. The location of the Los Pumas Manganese Project consisting of 7 granted exploitation concessions covering an area of 1,209ha
The Los Pumas Battery Metal Manganese Project is located in Northern Chile, approximately 175km or 3 hours drive NE of Arica, the major port city in the region XV of Chile. Access from Arica to the Los Pumas Project is via the International Highway from Arica to La Paz to the regional administrative centre of Putre, then via the A23, and then a well-maintained gravel road into the project area.
Overview
The following subsections are provided consistent with ASX Listing Rule 5.8.1, with further information provided in the JORC Code (2012) – Table 1, which is attached to this announcement.
The Mineral Resource Estimate (“MRE”) was completed by Mr Kerry Griffin of Global Commodity Solutions (“GCS”) utilising the current status of drilling. The scope of work included:
- the importation and validation of all drill hole data including collar, survey, geological, structural mineralisation, oxidation and assay information, including any processing of new assay data.
- The interpretation and solid modelling of main structural features and the interpretation and surface and/or solid modelling of main mineralisation units.
- Statistical analysis – composite length, grade distributions, top-cuts and continuity analysis – variography (if applicable) for all mineralisation domains.
- Block model creation, estimation parameter optimisation (KNA), coding and attribute assignment, grade estimation and block model depletion, validation and classification.
- A memo outlining methods and results are included in the JORC Table 1 attached to this announcement.
The Company supplied GCS with validated drill hole data, topographic surface, density data, geological mapping data and all previous reports.
