Krakatoa Resources Limited (ASX: KTA) has received promising assay results from the reverse circulation (RC) drilling undertaken under the substantial 500m x 1.3Km lithium rich soil anomaly at the ex-tantalum mine, King Tamba in Western Australia.
All multi-element assay results for the RC drilling have now been received. Several discrete zones of LCT mineralisation have been identified showing enrichment in lithium, caesium, tantalum with minor rubidium.
One discrete zone encountered in drill hole DAL086 located near the Wilsons high-grade rock area showed similar enrichment in lithium as previously reported by the initial drilling in hole DAL042.
A significant zone of high tantalum, niobium and rubidium was intersected in DAL096 which remains open to the west.
The company is encouraged by this intersection and further investigation may be warranted.
The drilling programme was designed to cover the footprint of the lithium soil anomaly using a 200m drill line spacing and 50m hole spacing. Drill holes were angled at 60 degrees towards to southeast and drilled to test the vertical depth of at least 100m below surface in most cases. One line at the southern extent was drilled shallower. The programme consisted of 45 RC drill holes for 5966m of drilling. Samples were transported to Perth in two batches and selected to undergo multi-element analysis.
The King Tamba project has an existing JORC 2012 inferred mineral resource estimate of 5Mt @ 0.14% Rb2O with 0.05% Li2O credits.
The company may seek to update and expand the resource model using the new data from the 2023/24 drilling.
Drilling was undertaken by Topdrill who provided $600,000 in drilling equity as part of a placement announced on the 29 November 2023.
