Marquee Resources has successfully intersected antimony mineralisation in every hole of its initial drilling campaign at the Mt Clement Project, setting the stage for a maiden resource estimate and expanded drilling.
- Seven RC holes drilled, 100% intersecting antimony mineralisation
- Significant antimony and lead grades confirmed, including high-grade intervals
- New mineralised structures discovered, extending known mineralisation
- Maiden Mineral Resource Estimate due by end of August 2025
- Phase 2 drilling planned to target strike and depth extensions
Strong Start at Mt Clement
Marquee Resources Limited (ASX, MQR) has reported a highly encouraging outcome from its inaugural reverse circulation drilling program at the Mt Clement (Eastern Hills) Antimony Project in Western Australia. The company drilled seven holes totaling 1,346 metres, surpassing its initial plan of six holes, and impressively intersected antimony mineralisation in every hole. This 100% success rate underscores the robustness of Marquee's geological model and the potential scale of the deposit.
Significant Grades and New Discoveries
The drilling revealed multiple zones of antimony mineralisation, with notable intervals such as 8 metres at 1.05% antimony and 2.85% lead, and a standout 9 metres at 0.88% antimony including higher-grade sections. Lead mineralisation was also significant, with one interval showing 3 metres at 5.33% lead. These results not only confirm extensions to previously known mineralisation but also highlight newly discovered mineralised structures that could substantially increase the project's footprint.
Strategic Positioning and Market Context
Mt Clement lies adjacent to Black Cat Syndicate's Eastern Hills Antimony Mineral Resource, Australia's largest undeveloped antimony deposit. With global demand for antimony rising, driven by its critical role in flame retardants, batteries, and strategic alloys, Marquee is well positioned to leverage this trend. The consistency of mineralisation across all holes provides a solid foundation for the company's growth ambitions in this critical commodity sector.
Next Steps, Resource Estimate and Phase 2 Drilling
Marquee plans to release its maiden JORC-compliant Mineral Resource Estimate for Mt Clement by the end of August 2025. Meanwhile, the company is preparing for an extensive Phase 2 drilling campaign later this quarter, aimed at further delineating strike and depth extensions, particularly targeting the Taipan Zone at depth where mineralisation remains open. Pending multi-element assay results, including gold and silver, will further refine exploration targets and potentially enhance the project's value.
Technical Rigor and Transparency
The drilling program adhered to rigorous industry standards, with detailed geological logging, quality control protocols, and independent verification by competent personnel. Despite some drill hole deviations and complex geology, the data collected is considered robust for advancing resource estimation and planning further exploration.
Bottom Line?
Marquee’s consistent antimony hits and new structural insights at Mt Clement set the stage for a pivotal resource update and expanded drilling that could reshape its project potential.
Questions in the middle?
- How will the pending multi-element assays, including gold and silver, impact the overall resource and project economics?
- What is the expected timeline and scale for the Phase 2 drilling program, and how might it alter the resource footprint?
- How will Marquee position itself competitively alongside Black Cat Syndicate’s adjacent large antimony deposit?
