Astral finds high-grade gold beneath Theia and extends mineralisation south
Astral Resources has found more gold at Theia, part of its Mandilla project about 70 kilometres south of Kalgoorlie in Western Australia.
One drill hole found 33 metres of gold averaging 5.02 grams per tonne below the deposit’s current resource pit shell.
Other drilling found gold deeper underground and about 150 metres south of the current resource boundary.
Theia already contains about 1.4 million ounces of gold, and the new results may point to more that can be added.
The deep results could help show whether enough gold is present to support mining underground after the open pit reaches its economic limit.
Astral has completed 18 of 21 planned deep diamond drill holes, while its infill drilling at Theia is continuing.
The company plans to move its drill rigs to other project areas during the December quarter and is targeting a definitive feasibility study in the March quarter of 2027, subject to heritage approvals.
Astral Resources reported high-grade gold beneath the Theia deposit at its Mandilla project in Western Australia.
A diamond drill hole intersected 33 metres grading 5.02 grams of gold per tonne, below the current resource pit shell.
Two holes south of Theia’s resource boundary also intersected gold, indicating possible extensions of mineralisation.
The results add to Astral’s assessment of Theia’s potential for underground mining and further resource growth.
The company said its deep-drilling program was nearing completion, with 18 of 21 planned holes completed.
- Who
- Astral Resources, an Australian gold exploration and development company.
- What
- Drilling found high-grade gold beneath Theia and further gold south of its resource boundary.
- When
- The results were reported on 13 October 2026.
- Where
- Theia, part of the Mandilla gold project, 70 kilometres south of Kalgoorlie, Western Australia.
- Why
- The drilling is assessing the scale and continuity of gold at depth and potential southern extensions, including prospects for underground mining and resource growth.
This story does not have two clearly opposing sides.
A previous drill hole intersected 52.75 metres grading 4.67 grams of gold per tonne from 445.25 metres.
Astral reported new deep-drilling results, including a 33-metre interval grading 5.02 grams of gold per tonne.
Astral had completed 18 of 21 planned diamond holes in the Theia Deeps program.
Astral planned to prepare drill pads at Spargoville and Kamperman and move its rigs to those programs.
Astral was targeting completion of its definitive feasibility study, subject to timing of heritage surveys and approval submissions.

What people are saying
These are important results as we work to establish the scale and continuity of higher-grade mineralisation at depth that could potentially support future underground extraction once we reach the economic base of the Theia Open Pit.
Equally encouraging are the results from drill-holes AMRCD466 and AMRCD467, drilled approximately 150 metres south of the current mineral resource, where we have intersected further significant zones of open pit gold mineralisation, highlighting further opportunities for resource growth at Theia.
