New Sulfide Discovery at Dante Raises Questions on Resource Scale and Depth Potential
Terra Metals has announced a significant new discovery of platinum group metal, copper, and nickel sulfide mineralisation at the SW6 target within its Dante Project, signalling a promising expansion of its mineral resource base.
- New PGM-Cu-Ni sulfide discovery confirmed at SW6 target
- Multiple thick mineralised zones with grades up to 1.57 g/t PGE3
- Downhole EM survey identifies strong off-hole conductor indicating deeper mineralisation
- Discovery suggests a fertile magmatic feeder conduit system analogous to world-class deposits
- Pending assays from diamond drilling expected to clarify extent and grade
Discovery at SW6 – A New Chapter for Dante
Terra Metals Limited (ASX – TM1) has revealed a significant breakthrough at its Dante Project in Western Australia's West Musgrave region, confirming a new zone of platinum group metal (PGM), copper, and nickel sulfide mineralisation at the SW6 target within the Southwest Prospect. The initial assays from reconnaissance drilling have intercepted multiple thick mineralised intervals, with grades reaching up to 1.57 grams per tonne of combined platinum, palladium, and gold (PGE3), alongside elevated nickel and copper concentrations.
Drilling Results and Geological Significance
The first two drillholes, SWRC030 and SWRC031, returned broad zones of mineralisation, including 47 metres at 1.01 g/t PGE3 and 26 metres at 1.16 g/t PGE3 respectively, both ending in mineralised ultramafic rocks. A diamond tail extension on SWRC031 (SWDD006) visually intercepted multiple zones of net-textured to semi-massive sulfides, a hallmark of potentially high-grade mineralisation. These findings are supported by downhole electromagnetic (DHEM) surveys that identified a robust off-hole conductor approximately 60 metres from the drillhole, suggesting the mineralised system may thicken or upgrade at depth.
Implications for the Dante Project
Managing Director and CEO Thomas Line described the discovery as a "very important step forward," highlighting that the grades, thicknesses, and continuity observed align with expectations for a fertile feeder conduit system. This system is geologically analogous to renowned global deposits such as the Sudbury Offset Dykes and the Platreef in South Africa, both known for hosting world-class PGM-Ni-Cu sulfide mineralisation.
The SW6 discovery adds a new dimension to the Dante Project, which already boasts a substantial 148 million tonne mineral resource dominated by titanomagnetite reefs. The presence of this distinct sulfide mineralisation style within the Southwest corridor underscores the complexity and potential scale of the magmatic system at Dante.
Next Steps and Market Outlook
While assay results from the diamond tail extension are still pending, the integration of geochemical data, geophysical modelling, and ongoing drilling will be critical in refining the geometry of the mineralised conduit and prioritising future drill targets. Terra Metals plans to continue its aggressive exploration program through 2026, aiming to delineate the extent of this new sulfide system and assess its economic potential.
Investors and analysts will be watching closely as further assay results emerge, which could materially impact the valuation and strategic outlook for Terra Metals and its flagship Dante Project.
Bottom Line?
Terra Metals’ SW6 discovery at Dante hints at a deeper, richer sulfide system that could redefine the project’s potential.
Questions in the middle?
- What will the pending assays from the diamond tail reveal about grade and continuity?
- How extensive is the off-hole conductor and what size mineralised body does it represent?
- Could this new sulfide system materially increase the Dante Project’s overall resource and economic value?
