Australia's top gold miner Northern Star names Glencore executive Suresh Vadnagra as CEO

Australia's largest gold producer, Northern Star Resources, has appointed senior Glencore executive Suresh Vadnagra as its next chief executive officer, betting on an experienced mining operator to steer the company through operational challenges and growing pressure from activist investor Elliott Investment Management.

Vadnagra, currently head of Glencore's nickel and zinc industrial assets, will take over as managing director and CEO on October 5, succeeding Stuart Tonkin, who announced in May that he would step down after leading the company for a decade. Until then, Northern Star chief financial officer Ryan Gurner will serve as interim CEO.

The appointment comes less than a month after Elliott disclosed it had built a stake worth about A$1 billion (around $716 million) in the Perth-based miner, urging the company to overhaul its leadership, strengthen board oversight and conduct a comprehensive strategic review to improve shareholder returns.

In a statement on Thursday, Northern Star said Vadnagra's appointment followed an extensive global search involving both internal and external candidates from the gold, diversified mining and broader resources sectors.

"Suresh is an accomplished mining executive with the experience and capabilities to unlock the full potential of our assets and our people," outgoing chairman Michael Chaney said.

Activist pressure mounts

The leadership change comes at a pivotal moment for Northern Star, whose shares have significantly underperformed despite gold prices touching record highs earlier this year.

Elliott has argued that the company has failed to capitalise on favourable market conditions because of operational setbacks, project delays and repeated downgrades to production guidance. The hedge fund has also criticised Northern Star's disclosure standards, saying they lag those of global mining peers.

When announcing its investment in June, Elliott called for the appointment of "a world-class external CEO with deep operational and turnaround experience" to restore operational discipline and rebuild investor confidence.

Following Thursday's announcement, Elliott said it looked forward to engaging with the company's new leadership but maintained that broader governance reforms remained necessary.

"The need for substantial board enhancement and a comprehensive strategic review has not diminished," the activist investor said.

Vadnagra brings more than two decades of international mining experience across more than 25 operations spanning open-pit and underground mines, smelters and refineries.

Before joining Glencore, he held senior leadership roles at former Australian gold producer Newcrest Mining, where he oversaw major projects, technical services and technology teams. His experience in both precious and base metals is expected to help Northern Star improve operational performance across its expanding portfolio.

As part of his remuneration package, Vadnagra will receive an annual base salary of A$2.2 million, a A$1.6 million sign-on payment and A$4 million in sign-on share rights, which will vest in stages through October 2028, subject to shareholder approval.

Board transition under way

Northern Star also announced a separate leadership transition at board level, confirming that chairman Michael Chaney will retire after the company's annual general meeting in November.

Deputy chairman Michael Ashforth will succeed him, completing a broader governance reshuffle that comes amid increasing investor scrutiny.

The company said Ashforth's experience in governance, capital allocation and corporate transactions would support Northern Star's next phase of growth.
