Northern Star Resources Limited (ASX: NST; OTC: NSTYY) is an Australian gold producer engaged in the exploration, development, mining, processing and sale of gold deposits from high-quality underground and open pit operations. The company operates three world-class production centres: Kalgoorlie (including KCGM Operations with the Fimiston open pit or Super Pit, Mt Charlotte underground and Fimiston Underground; Kalgoorlie Operations encompassing Kanowna Belle, South Kalgoorlie and Jubilee mines), Yandal (including Jundee, Carosue Dam with underground mines such as Karari, Whirling Dervish and Porphyry, and Thunderbox with Thunderground underground and open pit mines), and Pogo in Alaska; it also pursues targeted near-mine and in-mine exploration programs to extend asset lives beyond 10 years and maintains low-cost operations through efficiency initiatives. Northern Star sells refined gold and focuses on sustaining critical mass production, diversified assets and strong financial discipline, including consistent dividend payments to shareholders.
Founded in 2003 and headquartered in Subiaco, Western Australia, the company conducts its activities primarily in low sovereign risk Tier-1 jurisdictions of Western Australia and Alaska, serving global gold markets with a strategy targeting approximately 2 million ounces per annum by FY26 through organic growth and expansions such as the KCGM Mill expansion to 27Mtpa by FY29.
In recent developments, Northern Star completed its A$5 billion all-share acquisition of De Grey Mining Limited in May 2025 via a scheme of arrangement, adding the Tier-1 Hemi gold development project in Western Australia's Pilbara region with 11.2 million ounces of Mineral Resources and 6.0 million ounces of Ore Reserves, forecast to deliver 530kozpa over the first 10 years and supporting group production growth to ~2.5Mozpa by FY29; the company intends to optimize Hemi's development using expertise from the KCGM expansion while retaining most of De Grey's team. Earlier in July 2025, Northern Star divested its 50% interest in the Central Tanami Project Joint Venture and adjacent exploration landholding to Mount Gibson Iron Limited for A$50 million in cash, streamlining its portfolio focus. These transactions enhance Northern Star's position as a low-cost global gold leader with pro forma Mineral Resources of 74.9Moz and Ore Reserves of 26.9Moz as of late 2024.
