• Auger drilling campaign commenced with ~600 of the planned 1,338 holes completed to date
  • Two additional licenses have been applied for
  • Bulga sits on the Ida Fault, a hotbed of activity for critical minerals exploration
  • RC drilling planned after high-priority targets identified


Special Report: Phase 3 auger drilling has commenced at Western Yilgarn’s Bulga project in WA, where neighbouring projects are proving the potential of the Ida Fault.

The region is a hotbed of activity. Most recently,  Western Yilgarn’s (ASX:WYX) recently arrived neighbour TechGen Metals (ASX:TG1) caught an absolute rocket after identifying high levels of lithium and other pathfinder elements, such as caesium tantalum and rubidium, in historical data.

This greenstone belt also contains Delta Lithium’s (ASX:DLI) advanced 12.7Mt @ 1.2% Li2O Mt Ida deposit, 50km to the south, while another recently arrived neighbour in Rio Tinto (ASX:RIO) also has tenure adjoining WYX.

Drilling continues

WYX’ Bulga project is comprised of four contiguous exploration licences and two applications which cover a combined area of ~477km2.

Geologists are currently undertaking mapping and ground truthing of Ni-Cu-PGE and lithium pegmatite targets with an intensive auger drilling campaign.

WYX says drilling is advancing, with ~600 of a total 1,338 planned holes in this round completed to date.

Once completed, the total number of holes drilled on the E36/1010, E36/1011, E36/1025 and E36/1028 licenses rises to a whopping ~3,684.

The infill program will provide an auger grid of 200m x 100m spacing across identified targets, with additional infill to 100m x 50m planned before an RC drilling campaign kicks off.


Additional leases

WYX says it expects to apply the same auger geochemistry exploration to two additional Bulga leases, which currently remain under application.

E36/1065 is a ~136km2 lease contiguous to existing leases and sharing northern, eastern, and western boundaries of the current tenements, while E36/1066 covers 138km2 lease and shares southern, eastern, and western boundaries.

The selection of the additional licenses is “predicated on prospectivity arising from first-pass exploration activities”.

WYX chair Peter Lewis says Bulga continues to grow and develop as a strategic asset.

“We are encouraged by our exploration results to date which we believe have contributed to the heightened exploration activity in the Yilgarn region of Western Australia,” he says.

“The 100%-owned Bulga exploration licences are a strategic asset which together with the Company’s Julimar West, Boodanoo and Sylvania projects position the company as a fast growing exploration company in one of Australia’s most prospective exploration regions.”
