The Australian Financial Review reported on Monday that Elliott Investment Management built a stake in Northern Star Resources (ASX: NST) that is significant enough to place it amongst the gold miner’s largest shareholders.

The publication, citing sources, said the Florida-based fund now owns roughly A$1 billion ($713.90 million) in Northern Star’s equity, representing 4% of the company. This, AFR added, would place Elliot amongst the top 5 shareholders, joining the likes of Van Eck Associates and BlackRock.

This stake was later confirmed by Elliot. In a presentation published on Monday, the activist shareholder outlined its vision for value creation from the Northern Star investment, highlighting the company’s “world-class gold mining portfolio”.

The Subiaco-based miner is currently one of the world’s largest gold producers, with three production centres across Western Australia and Alaska. Its biggest asset is the KCGM, host to one of Australia’s largest open pit gold mines.

The disclosure comes amid investor concerns over the company’s operations. This year, Northern has cut its production forecast twice, once in January due to “unplanned maintenance and operational hurdles” and then in March for weak performance and supply issues at KCGM.

Recently, its managing director Stuart Tonkin said he will be stepping down after a decade at the helm. The MD was seen as integral to the company’s growth through multi-billion-dollar acquisitions of Saracen Mineral Holdings and De Grey Mining.

Even with improved profits after last year’s gold price surge, Northern Star’s stock has slumped this year, falling as much as 30% despite reaching an all-time high in early February. In 2025, the company’s share price soared by three-quarters, benefiting from one of gold’s best-performing years.

In April, the company announced it would buy back about 1.6% of its shares. “We believe current share prices do not fully reflect the quality and future potential of our assets,” Tonkin said at the time.
