• High-grade gold mineralisation intersected below Samat and Sorowar open pit sulphide Ore Reserves
• Assay results pending for 20 additional drill holes, including 10 from Samat
• Exploration and resource definition drilling ongoing across multiple targets

St Barbara Ltd announced assay results from the latest 11 drill holes of its now complete FY25 resource definition, exploration and sterilisation drill program at the Simberi Operations in Papua New Guinea. The program comprised 61 holes for 10,463.5 metres, with assay results remaining pending for a further 20 diamond drill holes. Notably, the first holes from the maiden significant diamond drilling campaign targeting the Samat sulphide resource have delineated high-grade sulphide mineralisation immediately below the current Samat sulphide open pit Ore Reserve. Significant intercepts include 17 metres at 4.2 g/t Au from 53 metres in SDH620 and 43 metres at 2.1 g/t Au from 17 metres in SDH622 at Samat, as well as 8 metres at 18.9 g/t Au from 54 metres, including 3 metres at 45.9 g/t Au, and 55 metres at 1.2 g/t Au from 121 metres in SDH600 at the Sorowar - Pigiput Trend. The company is awaiting assay results for the remaining 10 holes from the 12-hole Samat resource definition drill program, as well as results from other target areas including Pigibo North, Pigicow-Botlu, Pigiput Northeast Trend and Pigibo-Botlu.

The company anticipates the return of assay results for most of the remaining 20 resource definition, exploration and sterilisation holes drilled to date during the September quarter.
