Kairos Minerals Ltd (ASX: KAI) has identified a number of new targets with 572 results of a 6,000 sample deep soil sampling at its 100%-owned Roe Hills Project.
Roe Hills is 100km east of Kalgoorlie, Western Australia and is nestled within a new spodumene-bearing pegmatite province hosting the Manna Li-Ta project.
The programme has already uncovered two 400m long lithium anomalies which collectively have been labelled the Crystal Palace Prospect. This prospect sits in the northeast corner of the Roe Hills tenements five km along-strike to the SW of Global Lithium’s 32.7 Mt @ 1.0% Li2O Manna lithium-tantalum deposit.
The Crystal Palace prospect is coincident with mapped, multiple pegmatites that strike northeast or northwest. The mapped pegmatites are two m to 10m+ wide, are extremely coarse-grained and contain green feldspars (amazonite-microcline), quartz, white mica, biotite and white feldspars.
At this stage it is unknown if lithium minerals occur within these pegmatites but rock samples have been submitted for chemical analysis. Further exploration, especially drilling, will determine the source of the surface lithium.
Deep soil samples are collected using a Kanga post-hole configuration with samples collected from a nominal one m depth. The sampling procedure is very low-impact and ensures no contamination from surface effects and increases the possibility of collecting a quality geochemical sample that is more likely to avoid highly-transported surface alluvium. Samples are sieved to -80 mesh and sent to Intertek for four-acid digest and low-level multi-element and gold analysis by ICP-MS (4A-MS48).
Previous surface soil sample results over parts of the northern Roe Hills tenement package could have potentially included highly transported alluvium. These anomalies that will be followed-up by current deeper soil sampling that will determine whether the anomalies reflected buried in-situ mineralisation or highly transported anomalies.
There are now multiple discoveries of spodumene-bearing pegmatites around the Cardunia Syenogranite,” Managing Director, Dr Peter Turner, said.
“Kairos can confirm a new lithium soil anomaly with coincident pegmatites at ‘Crystal Palace’ along strike from the Manna Li-Ta deposit in an area that has never been explored for lithium.
“We know that this area is fertile for spodumene-pegmatites in the shadow of the Manna Lithium deposit, and our 2.6 km-long Black Cat soil anomaly, which comprises coincident lithium, caesium, beryllium and tin, shows huge promise to be a Manna- lookalike to add to the target at Crystal Palace.
“Around 6,000 deep soils are being collected as part of this programme in the Roe Hills North area. This is the first step in generating a significant and reliable foundation dataset in the hunt for new lithium, gold, nickel-cobalt deposits over an area which has yet to be thoroughly sampled.
“We are reviewing a draft heritage protection agreement from the Native Title claimant which will provide an operating framework to pursue drilling activities over all lithium, gold and base metal anomalies we discover”.
