Southern Hemisphere Mining (ASX: SUH) has contracted R Munoz Drilling from La Serena, Chile to complete up to a 5,000m RC and Diamond drilling programme at its Llahuin Copper-Gold-Moly Project in Chile.
The programme aims to add to the endowment of Llahuin from the current 680kt CuEq resource ahead of a JORC resource update in H2 2025.
The drilling programme is designed to delineate the deeper core of the large Cerro-Ferro porphyry deposits (+2km strike) to increase tonnes at higher grades to add to the copper endowment towards establishing economic parameters for mining studies.
One key target hole is an extension of DDLLA004 which was drilled in 2013 to 644m, and lines up to the target zone north of Cerro for a lower cost extension to ~1,200m depth.
The RC drilling programme will initially focus on the near surface Cu-Au mineralisation intersected in 23LHRC042 (48m at 0.48% CuEq from surface) drilled last year. This is a new zone south of Ferro which was part of the southern soil anomaly and had not been previously drilled. It is a good opportunity to add near surface higher grade tonnes to the current resource.
Curiosity Copper-Gold Target - Southern Porphyry
The large Curiosity Copper-Gold Porphyry target will also be advanced with a possible deep diamond hole (RC pre-collar) once target depth refinement studies are completed.
A comprehensive 409 rock chip and pulp sampling program on a nominal 200m spaced grid has been completed with all samples assayed using four acid digestion and ICPMS, over the majority of the concession area to vector depth targets at Cerro-Ferro and Curiosity.
A number of these tested epithermal vein outcrops at Curiosity with highlight grades of up to 0.69% Cu, 7.38g/t Au, 8.3g/t Ag and 459ppm Mo adding support to the large-scale potential copper target at Curiosity.
Regular updates will be provided during the drilling and as assay results are received from the ALS laboratory in Santiago with first results expected mid-November.
