Summary
Diatreme Resources Limited has reported positive results from its aircore drilling program at the Si2 and Casuarina deposits, part of the Northern Silica Project in Far North Queensland. The drilling has confirmed the extension of the geological model for Si2, supporting dune thickness and mineralisation continuity, while Casuarina's initial drilling has improved geological understanding, highlighting its strategic importance for future development. These findings will contribute to updating the Mineral Resource Estimate for Si2 and potentially initiating a maiden estimate at Casuarina, fortifying Diatreme's silica sand resource base critical for the solar PV and glass sectors. The project, which has received Major Project Status, is advancing through environmental approvals, reflecting its alignment with critical minerals strategies.
