Krakatoa Resources Ltd (ASX:KTA) reports multiple lithium-cesium-tantalum (LCT) pegmatites have been confirmed under the soil anomaly at the King Tamba specialty metals project in Western Australia.
The assay results received today are from reverse circulation (RC) drilling undertaken beneath the substantial lithium rich soil anomaly — spanning 500 metres by 1.3-kilometres — completed in January 2024 at the ex-tantalum mine, King Tamba.
The drilling program involved 45 RC drill holes for 5,966 metres of drilling and was designed to cover the footprint of the lithium soil anomaly using a 200 metre drill line spacing and 50 metre hole spacing.
The multi-element assay results revealed several discrete zones of LCT mineralisation, showing enrichment in lithium, caesium, tantalum with minor rubidium.
Significant intersections include:
- 17 metres at 0.24% lithium oxide from 90 metres (DAL061)
- 6 metres at 0.25% lithium oxide from 4-metres (DAL086)
- 9 metres at 605ppm tantalum and 5 metres at 305ppm niobium from 17 metres (DAL096)
Krakatoa highlights the significant zone of high tantalum, niobium and rubidium intersected in DAL096, which remains open to the west. The company says it is “encouraged” by this intersection and that further investigation may be warranted.
The King Tamba project has an existing JORC 2012 inferred mineral resource estimate of 5-million tonnes at 0.14% rubidium oxide with 0.05% lithium oxide credits. The company says that it may seek to update and expand the resource model using the new data from the 2023/24 drilling.
