⚒️ Southern Hemisphere Mining Limited reports encouraging Molybdenum results from re-assaying pulp composites for Moly at its Llahuin Copper-Gold-Moly Project in central Chile.
The Company’s recent pulp compositing campaign utilising pXRF assays to highlight significant zones of Molybdenum (Mo or Moly) in historic drilling where Moly was not previously assayed (by previous management), and pulps then sent to ALS for assay.
- Better intercepts include:
- 150m at 375ppm Mo from 20m in drillhole RDLLA014 including 20m at 2,080ppm Mo from 80m
- 20m at 756ppm Mo from 110m in drillhole DDLLA018
- 70m at 256ppm Mo from 80m in drillhole RCLLA117
- The data shows the Moly is located in a ring around the edge of the core of the Central Porphyry deposit and a positive upside for the upgrade to the JORC resource in progress for H1 2025

A recent pulp compositing campaign highlighted significant zones of Moly in historic drilling that were not previously assayed. Only copper and gold were assayed at the time under prior company management.
The Moly price is currently ~$21/lb vs Copper at ~$4.20/lb so Moly is significant in context of Copper equivalent grade, and these results and others in progress will be included in the upgraded JORC resource for H1 2025.
A total of 450 ten metre pulp composites covering 4,500m drilling were sent for multi-element assay.
All results have been received and demonstrate a significant zone of Molybdenum at the Central Porphyry in a ring like zone around the edge of the main porphyry.
The ALS laboratory in Santiago completed the four-acid digest, ICPMS multi-element assays. These new assays will be incorporated into the new resource model.
Significant results are:
- 150m at 375ppm Mo from 20m in historic drillhole RDLLA014 including 20m at 2,080ppm Mo from 80m.
- 20m at 756ppm Mo from 110m in drillhole DDLLA018.
- 70m at 256ppm Mo from 80m in drillhole RCLLA117.
- 40m at 155ppm Mo from 90m in drillhole RCLLA134.
(All Copper and Gold results and other details for these holes and in the map below were previously reported to ASX 18 August 2013- 43-101 resource).

This has also highlighted areas where the Central Porphyry deposit is potentially open to the east/south-east and locations for new drillholes targeting an increase in tonnes and grade.
Background Work and Ongoing Programs.
The rockchip sampling program to refine the Cerro-Ferro and Southern Porphyry deposit footprint model has been completed and final assay results are due next week.
This program aims to define the nature and extent of the mineralising systems at the Cerro-Ferro and at the Southern Porphyry, which is a very large greenfield opportunity at the Llahuin Project.
Fathom geophysics will complete the modelling once the laboratory results have been received which will vector drilling plans for the upcoming drill program later this quarter.

Further modelling, drilling and other results will be reported in due course.
