Goldman Broad zones of mineralisation align closely with Theia MRE model
Astral Resources Limited (ASX:AAR) has reported further high-grade results from the ongoing in-fill reverse circulation (RC) drilling program at the Theia Deposit, part of its 100%-owned Mandilla Gold Project near Kalgoorlie in Western Australia.
Assays from 29 new drill holes (totalling 3,233 metres) continue to demonstrate strong alignment with the existing Mineral Resource Estimate (MRE), reinforcing the consistency and continuity of gold mineralisation across the deposit.
Among the standout results were:
- 14 metres at 6.89g/t Au from 57m, including 2 metres at 36.4g/t Au from 63m (hole AMRC052)
- 14 metres at 4.10g/t Au from 44m, including 1 metre at 28.0g/t Au from 55m (hole AMRC040)
- 1 metre at 53.0g/t Au from 38m (hole AMRC049)
- 21 metres at 2.26g/t Au from 104m, including 1 metre at 34.3g/t Au from 104m (hole AMRC045)
- 14 metres at 2.47g/t Au from 105m, including 1 metre at 17.1g/t Au from 113m (hole AMRC059)
The Theia RC in-fill program now includes results from 46 holes (5,263 metres), which continue to correlate well with the current Theia MRE of 33.3Mt at 1.1g/t Au for 1.15Moz of contained gold (announced on 3 April 2025).
So far, approximately 50% of the 10,000-metre RC program has been completed, with 75 holes drilled for 8,433 metres and assays pending for 29 holes totalling 3,285 metres.
In addition to the RC program, a 3,000-metre diamond drilling campaign is underway at Mandilla. This phase targets high-grade structures within the Theia Deposit and deeper extensional zones on the eastern flank.
Astral Resources’ Managing Director Marc Ducler said:
As the results for the Theia in-fill program are received, our confidence in the robustness of the Mineral Resource Estimate continues to increase.
Whilst not to oversimplify this process, this latest batch of results consists of 29 holes, 18 of which returned a reported interval in excess of 10-gram x metres! Of the four holes that did not intersect significant mineralisation, three were drill tests beyond the known extents of the deposit.
Broad zones of high-grade gold mineralisation have been a stunning feature of this in-fill program so far and, with these results to hand, we are getting more confident and more excited about progressing the Theia deposit into production as soon as possible. We have an ideal starter pit location with high-grade mineralisation being defined to an almost grade control standard already.
With our next round of diamond drilling now underway, three rigs are currently operating at Mandilla.
Once the Theia in-fill RC program is completed, the rig will be relocated to Feysville to commence a 7,000m program, designed to extend the Kamperman deposit and follow up areas of gold anomalism identified by historical air-core and RC drilling within the broader tenement package.
