Full Summary

Astral Resources NL (ASX: AAR) has released assay results from the next 56 holes (4,970m) of its ongoing in-fill reverse circulation (RC) drill program at the Theia deposit, part of the Mandilla Gold Project in Western Australia. The results continue to validate the geological model and Mineral Resource estimates for Theia, with best results including 31m at 3.03g/t Au and 19m at 2.70g/t Au. These results support the conversion of the Stage 1 open pit inventory to the higher-confidence-level Measured Mineral Resource category, de-risking the early years of mine development. The in-fill program, designed to reduce the average drill spacing to 12.5m by 12.5m, is ongoing with 151 holes for 15,131 metres completed to date. Astral Resources aims to complete the entire Stage 1 inventory as Measured Mineral Resources by the end of 2026.

Guidance

Theia deposit hosts a Mineral Resource Estimate (MRE) of 41.0Mt at 1.1g/t Au for 1.4Moz of contained gold.

Outlook

The in-fill program is expected to continue throughout the remainder of 2026, supporting the Mandilla Gold Project Definitive Feasibility Study and project financing.
