• Sustained exploration investment across assets supports long-term value and near-mine growth
• Key highlights include new underground areas at KCGM, new prospects at Kalgoorlie and Yandal, and extensional drilling at Pogo
• Exploration spend of A$225 million in FY26 focused on near-mine opportunities and largest asset KCGM

Northern Star Resources Ltd (ASX: NST) is pleased to announce an update on its FY26 exploration program. The company's exploration efforts continue to deliver value-creating organic growth opportunities, strengthening its track record of exploration success. The FY26 exploration spend of A$225 million is heavily focused on near-mine opportunities, with 73% allocated to in-mine growth and the remaining 27% to regional exploration. Key highlights across the company's production centres and development project include: At KCGM, new underground areas continue to facilitate increased drilling activity aimed at providing near-term optionality and long-term visibility, with the Fimiston South mineralisation footprint extending up to 800 metres below the existing Mineral Resource. At Kalgoorlie Operations, a new opportunity has been identified at the Ballarat-Last Chance Project, immediately west of the Red Hill Mineral Resource, while drilling at the recent Hercules discovery builds confidence. In the Yandal region, mine life extension opportunities have been identified proximal to current mining infrastructure. At Pogo, extensional drilling has highlighted several high priority targets, reflecting the scale of this world-class system. At the Hemi Development Project, future potential growth opportunities have been identified adjacent to the existing Resource, while early regional success has been achieved at Mt Berghaus. Northern Star's exploration success has added immediate life to existing operations from near-mine extension, as well as yielding significant new discoveries. The company's geology team remains focused on high-quality brownfield projects within the existing footprint of its mines and surrounding districts.

Northern Star's FY26 exploration program is focused on growing Mineral Resources at current operating mines, ongoing investment in underground drill locations to enable future exploration activities, advancing regional high priority projects and developing new targets, and ongoing infill drilling to advance recent discoveries and acquisitions. The company's exploration efforts continue to offer exceptional upside potential across its portfolio.
