Northern Star Resources (ASX:NST) has revised its annual production guidance to 1.6 to 1.7 million ounces from 1.7 to 1.85 million ounces, following a softer operational performance during the December quarter of 2025.
Gold sales during Q4 2025 were impacted by numerous isolated negative events coinciding at the company’s operations. The total sales were 348,000 ounces, resulting in the first half of FY2026 gold sales of 729,000 ounces.
For the Kalgoorlie production centre in Western Australia, gold sales totalled 203,000 ounces. At KCGM, gold sales were 110,000 ounces and the Yandal production centre sales totalled 91,000 ounces.
The quarterly operations were also affected by several unplanned maintenance and operational challenges. As a result of lower gold sales across the company’s three production centres, cost performance was impacted.
The company notes the processing plant at the Kalgoorlie operations is expected to return to normal operations early this month, with throughput expected to remain variable during H2 FY2026 as Northern Star transitions from the existing plant to a new expanded mill. The mill is on track for commissioning in early FY2027.
Northern Star Resources is a gold producer focused on its three production centres in Western Australia and Alaska.
