Theia Deeps Keeps Growing: Astral Resources Delivers More High-Grade Gold Below the Resource Shell

Astral Resources (ASX: AAR) has reported new assay results from its deep diamond drilling programme at the Theia Deposit, the cornerstone asset of the 100%-owned Mandilla Gold Project in Western Australia. The Astral Resources Theia Deeps high grade gold drilling results at Mandilla Gold Project confirm that high-grade gold mineralisation continues to extend beyond the base of the April 2026 Mineral Resource shell, prompting the company to significantly scale up the programme.

Three drill holes, AMRCD262, AMRCD376 and AMRCD378, have returned assay results covering 1,817.3 metres of core, with each hole intersecting broad zones of gold mineralisation sitting outside the current resource boundary. The standout intersection from this batch is 52.75 metres at 4.67 g/t gold from 445.25 metres in AMRCD378, an interval that includes 0.34 metres at 477 g/t gold from 487.3 metres — a visible gold result that underscores the high-grade character of this system at depth.

Reflecting the programme's results to date, Astral has expanded the Theia Deeps drilling campaign from its original scope of 6 holes (3,000 metres) to 21 holes (11,000 metres), more than a threefold increase. Thirteen holes have been completed to date.

Why This Company Warrants Continued Attention

Astral Resources is running a multi-rig exploration campaign at a project that already holds more than 2 million ounces in total Mineral Resources and a Pre-Feasibility Study indicating substantial project economics. The Astral Resources Theia Deeps high grade gold drilling results at Mandilla Gold Project continue to deliver intervals extending beyond the current resource boundary, with the programme now more than tripled in scope from its original design.

With the DFS advancing, in-fill drilling at Theia ongoing, and exploration catalysts at Feysville and Spargoville scheduled for the September quarter, the company has flagged a period of substantial activity across its project portfolio in the second half of 2026.

Key takeaway: Astral Resources has built a resource base of more than 2 million ounces across three Western Australian gold projects, supported by a PFS indicating billion-dollar-level project economics at Mandilla. The Astral Resources Theia Deeps high grade gold drilling results at Mandilla Gold Project continue to extend the deposit beyond its current boundaries. With multiple resource, study and exploration catalysts flagged for the months ahead, developments at Mandilla, Feysville and Spargoville warrant continued monitoring by investors.
