Northern Star appoints Glencore executive Suresh Vadnagra as next CEO

Northern Star Resources has appointed Glencore executive Suresh Vadnagra as its next chief executive and managing director, setting up a leadership handover at Australia’s biggest gold miner.

The move comes after months of investor pressure and follows a broader board refresh at the company. Northern Star said Vadnagra’s appointment followed a comprehensive search process.

Stuart Tonkin will step down as chief executive in October 2026. Northern Star has not publicly given a precise date for Vadnagra’s start, but the planned transition ties his arrival to Tonkin’s departure.

Leadership reset

Vadnagra is currently head of Glencore’s nickel and zinc industrial assets. He also previously worked at Newcrest Mining, giving him experience across two of the mining sector’s better-known names.

That background appears to fit Northern Star’s preference for an external operator with large-company experience. The appointment also gives the board a new executive team member as it responds to investor scrutiny over performance and strategy.

Northern Star said deputy chairman Michael Ashforth will succeed chairman Michael Chaney later in 2026, with that change framed as part of a planned succession.

Pressure from Elliott

The leadership changes have landed against the backdrop of pressure from Elliott Investment Management, which has been pushing Northern Star for strategic and board changes.

Reuters and The Wall Street Journal first reported the appointment early on July 2, 2026. The Australian later reported that Elliott remained dissatisfied with the shake-up even after the CEO and chair announcements.

That matters because the appointment does not appear to be the end of the governance debate. Elliott has been pressing for more change, and the company is still facing scrutiny over operating performance and investor expectations.

What happens next

The immediate watchpoint is October, when Tonkin is due to step down and Northern Star’s leadership transition becomes operational.

Investors will also be watching for any further board changes or strategic decisions, including whether the company outlines new capital allocation priorities or asset review work.

For now, the board appears to be betting on a high-profile external hire to steady the company and reset confidence. Whether that is enough to satisfy Elliott remains uncertain.
