Astral reports record gold assay at Theia deposit near Kalgoorlie
Astral Resources found a record gold grade in drilling at its Theia deposit near Kalgoorlie, Western Australia.
The standout result was a narrow 0.34-metre section grading 1,146.3 grams of gold per tonne, within a wider 31-metre interval.
Theia is part of Astral’s Mandilla project, and the deposit already holds about 1.4 million ounces of the project’s 1.74 million-ounce resource.
Drilling also found gold below the current open-pit resource shell, suggesting there may be more mineralisation at depth.
Astral has expanded its deep drilling to 25 holes and is aiming for spacing that could support a future estimate of inferred resources.
The company is also drilling to refine plans for the early open pit, ahead of a definitive feasibility study for Mandilla.
Assays from two more deep holes are pending, and the deep drilling program is expected to resume in January.
Astral Resources reported a record gold assay of 1,146.3 grams per tonne from drilling at its Theia deposit near Kalgoorlie.
The assay came from a 0.34-metre interval within a broader intersection of 31 metres at 13.5 grams per tonne.
Other drilling results included a 111-metre interval below the current resource pit shell.
Astral expanded its deep diamond drilling program to 25 holes for 13,400 metres to test the deposit and support potential resource estimates at depth.
- Who
- Astral Resources, an Australian mining company.
- What
- It reported a record gold assay from drilling at the Theia deposit.
- When
- Stockhead published the report on 10 November 2026.
- Where
- Theia deposit, part of the Mandilla project near Kalgoorlie.
- Why
- The drilling is testing for gold below the current resource shell and could support potential inferred resource estimates at depth.
This story does not have two clearly opposing sides.
Assays from three Theia Deeps holes revealed the record-grade interval and other gold intersections.
Astral enlarged the deep diamond drilling program to 25 holes for 13,400 metres.
The deep drilling program is expected to resume.

What people are saying
The Theia Deeps drill program has delivered some exceptionally high-grade individual assays along with broad zones of gold mineralisation, reinforcing the significant endowment of the Theia mineral system and the potential to grow the current Resource
The focus of the Theia Deeps program has switched to in-fill within the main gold mineralisation ore shoot
