Deep Drilling Extends Theia Gold Mineralisation Beyond Resource Shell

Astral Resources (ASX:AAR) has pushed the boundaries of its flagship Theia Deposit at the Mandilla Gold Project in Western Australia, revealing significant gold mineralisation at depths far below the current resource pit shell. The latest assays from deep diamond drilling holes AMRCD259 and AMRCD264 confirm broad zones of gold over hundreds of metres, including a standout 22 metres at 0.63g/t Au from 714 metres in AMRCD259. This intercept lies nearly 400 metres beneath the $4,500/oz resource shell, underscoring the potential scale of the mineral system.

Adding further intrigue, visible gold was logged at 767 metres down-hole in AMRCD259, highlighting high-grade pockets within the broader mineralised envelope. AMRCD259 also returned a remarkable 45.53 metres at 2.15g/t Au starting from 357 metres, peppered with narrow but intense assay spikes up to 170.8g/t Au over 0.3 metres.
