Kali Metals (ASX:KM1) launched its highly anticipated Phase 2 reverse circulation drilling programme at the Marble Bar Lithium Project in the Pilbara region of Western Australia.
The follow-up campaign follows a maiden drilling round that identified spodumene-bearing pegmatites, signalling the potential for a substantial lithium discovery.
The current phase is designed to test the strike extent and depth continuity of these mineralised zones, specifically focusing on high-priority targets within the Archer deposit and surrounding prospects.
The mobilisation of a specialised RC rig to the site underscores the company’s commitment to accelerating exploration amidst growing global demand for battery-grade lithium.
Geologists at Marble Bar are targeting several prominent outcropping pegmatites that returned high-grade rock chip samples during earlier reconnaissance.
By utilising advanced geochemical mapping and geophysical data, the technical team aims to refine the geological model and define a maiden JORC-compliant mineral resource estimate in the near future.
Marble Bar's location—adjacent to established Tier 1 lithium operations—provides Kalamazoo with infrastructure advantages and a proven geological pedigree.
As the energy transition continues to fuel the appetite for critical minerals, this drilling campaign represents a pivotal milestone for shareholders.
Results from the initial batches of assay samples are expected within the coming weeks, which will provide further clarity on the scale and grade of the lithium mineralisation at depth.
At the time of reporting, Kali Metals’ share price was $0.16.
