RareX drilling confirms copper-nickel system at Western Australia project
RareX confirmed a copper-nickel sulphide system through its first drilling at the Niobe prospect, part of its Khaleesi project in Western Australia.
One hole found 40 metres averaging 0.13% copper and 374 parts per million nickel, including a higher-grade section.
The sulphides occur in a layered gabbro, a type of rock that can host magmatic mineral deposits.
Drilling also found gallium-rich soil above the Niobe granite, including intervals with up to 75 grams per tonne of gallium oxide.
The project covers a large area, but drilling tested only two lines, and much of the intrusion remains unexplored.
An induced polarisation survey is due in November to help identify stronger sulphide concentrations and guide further drilling.
RareX says first-pass drilling at its Khaleesi project in Western Australia confirmed a copper-nickel sulphide system at the Niobe prospect.
Hole KRC012 returned 40 metres at 0.13% copper and 374 parts per million nickel from 110 metres.
The company also reported gallium-rich regolith over the Niobe granite.
The Niobe intrusion remains largely untested, and RareX said the system is open.
An induced polarisation survey was due to start in November to help target follow-up drilling.
- Who
- RareX, an Australian-listed exploration company.
- What
- First-pass drilling confirmed a copper-nickel sulphide system and gallium-rich regolith at its Khaleesi project.
- When
- The results were reported on November 3, 2026; the drilling campaign took place in 2026.
- Where
- The Khaleesi project in Western Australia’s East Yilgarn, including the Niobe prospect.
- Why
- The drilling tested mineralisation targets; an induced polarisation survey is planned to help locate stronger sulphide concentrations.
This story does not have two clearly opposing sides.
RareX identified a copper zone in the field using pXRF, according to the company.
RareX carried out its maiden drilling campaign at Khaleesi.
Stockhead reported that laboratory assays confirmed copper-nickel sulphides and gallium-rich regolith at Niobe.
An induced polarisation survey was due to start at Niobe to help target follow-up drilling.

What people are saying
At Niobe we have confirmed a copper–nickel sulphide system within a layered mafic intrusion that sits beneath a large gravity anomaly, and the laboratory assays have confirmed the broad zone of copper we identified in the field.
Several holes stopped at, or just into, the top of the intrusion, so the system remains open and largely untested.
