Kali Metals has reported high-grade gold assay results up to 19.2 g/t from its Marble Bar Project in Western Australia, revealing a 1.4km gold-bearing outcrop. The company is gearing up for an expanded exploration campaign including drone surveys and a maiden drill program.
- Rock-chip samples up to 19.2 g/t gold at Marble Bar
- 1.4km gold-bearing quartz-rich potassic-altered granite zone identified
- Tiger and Sherman prospects extended with promising assay averages
- Upcoming drone magnetic surveys and mineralogical studies planned
- First-pass drilling program to target newly identified mineralised trends
High-Grade Gold Discovery at Marble Bar
Kali Metals Limited (ASX: KM1) has unveiled compelling exploration results from its Marble Bar Gold Project in the Pilbara region of Western Australia. Recent rock-chip sampling has returned standout assay grades, with the highest hitting 19.2 grams per tonne (g/t) gold. This discovery highlights a significant gold-bearing zone stretching approximately 1.4 kilometres along outcrop.
The gold mineralisation is hosted within a quartz-rich, potassic-altered granite zone, up to 30 metres wide at surface and interpreted to be around 10 metres thick. These geological characteristics suggest a robust hydrothermal system, potentially analogous to known deposits in the region.
Expanding Prospects and Exploration Scope
The company’s detailed sampling at the Tiger Gold Prospect has mapped a strike length of about 1.1 kilometres, with 37 rock-chip samples averaging 2.3 g/t gold after applying a top-cut of 10 g/t. Nearby, the Sherman Gold Prospect has been extended to roughly 300 metres, with samples averaging 2.4 g/t gold. These results build on earlier soil sampling campaigns that delineated a gold-in-soil anomaly now extending over 9 kilometres.
Managing Director Paul Adams expressed optimism about the potential for discovering a previously unknown gold system, especially given the lack of prior drilling along this mineralised trend. The company recently acquired additional tenements, including E45/6389, which may extend the mineralised zone further northwest.
Next Steps: Drone Surveys and Drilling
Kali Metals is advancing a comprehensive exploration program over the coming months. This includes high-resolution drone magnetic surveys across the Tiger and Sherman prospects, detailed mineralogical studies in collaboration with Microanalysis Australia, and further rock-chip sampling to refine the geological model. Heritage surveys are also underway to facilitate access for future work.
Crucially, these activities will inform the design of a first-pass drilling program aimed at testing the depth and continuity of the gold mineralisation. The company’s methodical approach, combining geophysical, geochemical, and mineralogical data, positions it well to unlock the full potential of the Marble Bar Project.
Strategic Significance in a Proven Gold Province
Located just 10 kilometres east of the town of Marble Bar, the project sits within a geological setting known for gold mineralisation, including the nearby Klondyke deposit. Kali Metals’ tenure covers 96 square kilometres, encompassing both granitic complexes and greenstone belts, which are classic hosts for gold deposits in Western Australia.
While the rock-chip samples represent point data and are not directly indicative of bulk grades, the consistent presence of gold associated with specific alteration zones is a strong exploration vector. The company’s ongoing work aims to translate these surface indications into a defined resource.
Bottom Line?
Kali Metals’ promising surface gold results set the stage for drilling that could redefine the Marble Bar gold potential.
Questions in the middle?
- Will the upcoming drill program confirm continuity and economic grades of the gold mineralisation?
- How will the mineralogical studies refine the understanding of the alteration and gold deposition processes?
- What impact will the expanded tenement holdings have on the scale and scope of the project?
