Trek Metals Extends Kuro Prospect to 750m with 60.1% Manganese Assays
Trek Metals reports exceptional high-grade manganese rock chip assays up to 60.1% Mn at its Kuro Prospect, extending mineralisation over 750 metres and aligning with strong gravity anomalies. Drill preparations and heritage assessments are underway to unlock the discovery’s full potential.
- Rock chip assays up to 60.1% manganese at Kuro Prospect
- High-grade mineralisation extends over 750 metres strike
- Strong gravity anomalies suggest larger hydrothermal system at depth
- Heritage impact assessment submitted with Traditional Owners
- Drill planning advancing to test priority targets
Exceptional Surface Grades Confirmed
Trek Metals Limited (ASX, TKM) has announced outstanding new assay results from its Kuro Prospect within the Christmas Creek Project in Western Australia's Kimberley region. Recent rock chip sampling has returned manganese grades as high as 60.1%, approaching the theoretical maximum purity of manganese oxide. These results not only confirm the discovery’s high-grade nature but also extend the known mineralised strike from approximately 320 metres to 750 metres.
Geophysical Evidence Points to Larger System
The high-grade surface mineralisation coincides with significant gravity anomalies detected in recent surveys, suggesting the presence of a much larger hydrothermal manganese system concealed beneath shallow cover. The mineralised corridor spans roughly 400 metres in width, with multiple untested gravity highs along strike and down dip. This geophysical signature bolsters confidence that the surface rock chips are the tip of a substantial mineralised body.
Advancing Towards Drill Testing
With heritage impact assessments submitted in collaboration with the Yi-Martuwarra Ngurrara and Jaru Traditional Owners, Trek is progressing drill planning to test these priority targets. The company emphasises that the mineralisation remains open along strike and at depth, making Kuro a compelling walk-up drill target with district-scale potential. CEO Derek Marshall highlighted the rarity of such high-grade manganese mineralisation and its alignment with Australia's Critical Minerals Strategy, positioning Trek to benefit from growing demand in steelmaking and energy technologies.
Strategic Importance and Next Steps
Manganese is a critical mineral essential for decarbonisation and infrastructure development, and the Kuro discovery aligns well with national priorities. Trek plans to integrate further geophysical datasets, including helicopter electromagnetic surveys and petrophysical testing, to refine drill targets. Ongoing exploration across the broader Christmas Creek Project will continue alongside heritage surveys and eventual drilling, aiming to unlock the full scale and commercial viability of this high-grade manganese system.
Bottom Line?
As drill rigs prepare to move in, Kuro’s exceptional grades and geophysical footprint could redefine Trek Metals’ role in Australia’s critical minerals landscape.
Questions in the middle?
- What will drilling reveal about the true depth and continuity of the manganese mineralisation?
- How quickly can heritage approvals and environmental clearances be secured to commence drilling?
- What are the potential metallurgical characteristics and processing pathways for this high-grade manganese?
