Krakatoa (ASX:KTA) shows critical promise at King Tamba

Krakatoa Resources has confirmed an intersection containing high-grade rubidium 0.23% RbO2 from 82m downhole as part of RC drilling across multiple broad zones of rubidium mineralisation at its 100% owned King Tamba critical metals near Mt Magnet in Western Australia.

With Rubidium Carbonate (99% grade) commanding US$1,091.58 kg, the 70-metre thick pegmatite 800m south of known pegmatite complex revealed peak assays of 0.7% RbO2, O.47% Li2O and 0.16% Cs2O (DAL029.

Maximum Results reported for induvial assays are 0.70% RbO2, 0.42% Ta2O5 , 0.85% Li2O, 0.16% Cs2O and 0.08% Nb2O5.

Maiden JORC Mineral Resource Estimation work has now commenced using the characterisation of the mineralised rocks, with metallurgical test work starting soon.

The Company’s ASX-listed shares are 6.4c at Market Open.

Next Steps

Moving forward, the company intends to complete structural geology modelling and mineral deportment work at King Tamba before finalising a maiden mineral resource estimate (MRE) later this quarter. The potential to discover further mineralised pegmatites here is clear, including zones enriched in tantalum, lithium, and caesium. An aggressive geochemical sampling and drilling program is now being prepared for 2023 following the release of the MRE.

Exploration Target

In late 2021 the company defined an Exploration Target based on historical drill holes of between 1,470,000 to 3,185,000 tonnes with estimated grades of rubidium (500-2000ppm), Lithium and Niobium, Tantalum, Tin and Tungsten as reported in ASX Announcement November 8 2021. The potential quantity and quality of the Exploration Target are conceptual and, therefore, an approximation. There is insufficient exploration to estimate a Mineral Resource, and it is uncertain if the current drilling results will result in the estimation of a Mineral Resource. However, this is the objective of this drilling program.

The modelled pegmatite, which constituted the Exploration target, has 156 historical holes (5,071m) and 11 holes (1,066m) drilled by Krakatoa in 2017. Only four elements were assayed within the historical holes. The company expanded the analysis with a focus on rubidium, lithium, niobium, tantalum, tin and tungsten across the modelled target area.
