 Theia In-fill - Multiple High-Grade Zones of Gold
Key Points
  • High-grade assay results received for 20 holes (2,080m) of in-fill drilling at the Theia Deposit
  • Assay results for 82 holes (9,108m) now received, with results for final 17 holes pending
  • Drilling confirms consistent broad zones of high-grade gold mineralisation
Full Summary

Astral Resources NL (ASX: AAR) has received assay results for a further 20 holes (2,080m) of the recently completed 99-hole (11,121m) in-fill reverse circulation (RC) drill program at the Theia Deposit, part of the 100%-owned Mandilla Gold Project near Kalgoorlie, Western Australia. The in-fill drilling program was undertaken on a 12-metre by 12-metre drill density and aimed to increase the drill density over a panel of the Stage 1 Theia Pit, encompassing an area of 80 metres by 120 metres and to a depth of 150 metres. The latest assay results continue to confirm consistent broad zones of high-grade gold mineralisation, with intercepts including 22m at 1.65g/t Au, 19m at 3.53g/t Au, 18m at 6.67g/t Au, 39m at 2.98g/t Au, 25m at 3.20g/t Au, 27m at 3.23g/t Au, and 33m at 2.29g/t Au. With these latest results, assay results have now been received for 82 holes (9,108m) or approximately 82% of the program, with results from the final 17 holes (2,013m) pending. The Company has also reported assay results from six RC holes (1,332m) drilled to test a potential controlling structure sub-parallel to and immediately west of the Theia Deposit, with high-grade intersections including 1m at 24.8g/t Au and 8m at 1.06g/t Au. Astral's Managing Director said the in-fill drilling has reinforced the robust, high-grade nature of the Theia Stage 1 open pit, and the early drill results from Theia West are very encouraging, intersecting high-grade mineralisation in an undrilled area.

Guidance

The Theia Deposit is crucial to the overall success of the Mandilla Gold Project, contributing 1.1Moz or 75% of the 1.48Moz total in the production case outlined in the Mandilla Pre-Feasibility Study.

Outlook

Astral continues to advance the Mandilla Definitive Feasibility Study, which is due for completion in the June Quarter of 2026. The Company also has two ongoing drill programs, with a diamond program at Theia and an extensional RC program at the Kamperman Deposit within the Feysville Gold Project, with the RC rig to be relocated to Mandilla to further test the new Theia West target once the Kamperman program is completed.
