The high-grade mineralisation occurs predominantly within an argillaceous metasediment which lies<br />
immediately below the Mesoproterozoic Gardiner Sandstone unit and directly above the unconformable<br />
contact with the older Archean Browns Range Metamorphics. The resource estimate includes three separate<br />
zones including the Iceman prospect, which are southeast of the main zone at Dazzler. Mineralisation also<br />
occurs within the Browns Range Metamorphics but this tends to be lower grade and has not been included<br />
in the resource estimate. Further drilling was completed in the second half of <strong>2020</strong> with infill drilling and step<br />
out drilling to the northwest.<br />
