Krakatoa Resources Ltd (ASX:KTA) has resumed its 6,000-metre Phase 2 pegmatite exploration drilling program at the King Tamba ex-tantalum mine in the Murchison Province of Western Australia.
The company’s exploration team and drilling contractors returned to the site today to complete the remaining 22 reverse circulation (RC) drill holes on the three southernmost drill lines.
This team completed 27 holes for just under 4,000 metres in December, which returned significant pegmatite intersections from multiple drill holes.

The mineralogy of the pegmatites drilled so far has shown variable proportions of quartz, feldspar and mica, along with traces of accessory minerals such as fluorite and tourmaline in some places.
Multiple highly micaceous zones, sharing visual similarities with the surface samples taken from the Wilsons prospect, were intersected.
Last year, KTA identified 250 metres of continuous outcrop with results of up to 4.3% Li2O, 1.7% rubidium and 0.5% caesium at Wilsons.

Additionally, drilling has uncovered large pegmatites of more than 10 metres downhole width across sections, although the company warned that the presence of pegmatites did not necessarily confirm the presence of lithium mineralisation.
The presence can only be confirmed with assaying.
