Astral Expands Theia Deeps with Broad Gold Intercepts

14 July 2026 | Western Australia - Astral Resources has reported further strong diamond drilling results from Theia Deeps, part of the company’s 100%-owned Mandilla Gold Project near Kalgoorlie in Western Australia.

The deep drilling program is testing resource growth potential beneath the cornerstone 1.4Moz Theia Deposit.

Significant results from AMRCD260 include:

• 52.60m at 1.48 g/t gold from 389.4m
• 7.0m at 5.22 g/t gold from 583.0m
• 43.86m at 0.87 g/t gold from 605.0m
• 16.52m at 1.54 g/t gold from 272.48m

Results from AMRCD261 included:

• 54.0m at 2.38 g/t gold from 316.0m
• 5.0m at 2.72 g/t gold from 582.0m
• 14.77m at 0.78 g/t gold from 601.13m

Astral said AMRCD261 ended in mineralisation, with visible gold observed on the non-sample side of the core at 603.33m down-hole.

Why it matters: Theia is already a major gold deposit, and these deeper results point to further resource growth potential below and around the current April 2026 Mineral Resource shell.

Managing Director Marc Ducler said the Theia Deeps program continues to show significant growth potential beyond the current resource, while also confirming mineralisation inside the current pit shell.

Astral has now completed nine holes in the expanded deep diamond drilling program, which has grown from an original six-hole, 3,000m program to 12 holes for 7,500m.

For Western Australia’s gold sector, Mandilla remains one of the more important open-pit development stories near Kalgoorlie, with deep drilling continuing to test whether Theia can grow into a larger and longer-life gold system.
