Sulfide System Expanded at Southwest
- The Southwest magmatic PGM-Cu-Ni sulfide discovery footprint continues to grow
- Shallow first-pass drilling at SW5 & SW1 defines thick PGM-Cu-Ni sulfide, indicating continuity of at least 650m width, 850m in length and 348m depth (open)
- PGE71 re-assays confirm the presence of high-value rhodium (Rh), iridium (Ir), osmium (Os) and ruthenium (Ru), reinforcing the primary magmatic sulfide model
Recent drilling at the Southwest Prospect continues to demonstrate the scale and coherence of the PGM-Cu-Ni sulfide system developed along the SW5-SW6 trend. Mineralisation has now been intersected across an 850-metre strike corridor and a lateral width of approximately 650 metres, with multiple holes finishing in sulfide mineralisation and the basal contact yet to be identified. The thickness and consistency of these sulfide-bearing sequences indicate emplacement adjacent to a major magmatic feeder zone within the Dante intrusion. Importantly, new PGE7 re-assays from the Southwest discovery holes confirm the presence of high-value iridium-group PGEs (Rh-Ir-Ru-Os), a geochemical signature characteristic of sulfide accumulation in conduit-proximal positions where repeated magma recharge promotes metal enrichment and upgrading. These results further strengthen the geological model for Southwest and support the potential for a high-tenor PGE system capable of generating both broad mineralised packages and discrete high-grade intervals. Drilling at SW2 has identified a large sulfide-rich Iron Oxide Apatite ('IOA') intrusive complex carrying Fe-Ti-P-Sc-V-Zr and rare earth elements. Although distinct in style from the PGE-Cu-Ni sulfide system, the SW2 intrusive confirms the presence of a multi-pulse, long-lived magmatic centre at Southwest, consistent with a fertile and chemically diverse intrusive environment. Together, these results highlight the substantial mineralising potential of the Southwest sector of the Dante Project.
The next phase of drilling will aim to refine the geometry of the sulfide body, test down-dip continuity of high-tenor zones, and clarify the spatial and magmatic relationship between SW5, SW6 and SW2.
