Astral Resources reports strong assay results from infill drilling at Theia, underpinning resource upgrades and de-risking early Mandilla mine development near Kalgoorlie.

• High-grade gold assays reinforce Theia Stage 1 resource model

• Ongoing infill drilling aims to upgrade resources to Measured category

• Mandilla hosts 2.07Moz gold resource with 1.08Moz Ore Reserves

• Program expected to continue through 2026 supporting feasibility

• Metallurgical tests confirm excellent gold recoveries and processing

Robust Gold Grades Support Stage 1 Resource Upgrade

Astral Resources (ASX:AAR) has delivered assay results from the first 47 holes of its ongoing infill reverse circulation drilling program at the Theia deposit, part of the Mandilla Gold Project near Kalgoorlie. The standout intercepts include multiple high-grade intervals such as 4 metres at 16.4 g/t gold from 58 metres, including a blistering 1 metre at 61.3 g/t, and several other shoots exceeding 20 g/t over short widths. These results validate the geological model underpinning the Stage 1 open pit resource and provide confidence to upgrade this inventory to the Measured Resources category.

Theia is the cornerstone deposit at Mandilla, contributing approximately 75% of the 1.48 million ounces targeted in the project's Pre-Feasibility Study (PFS). The current infill program aims to tighten drill spacing to 12.5 by 12.5 metres, a density sufficient for Measured Resource declaration, which is critical for de-risking the early mine stages.
