Northern Star Resources Ltd (ASX: NST) shares are under pressure on Thursday morning.
At the time of writing, the ASX 200 gold stock is down 4% to $18.65.
This compares unfavourably to a 2% gain by the S&P/ASX All Ordinaries Gold index in early trade.

Why are Northern Star shares falling today?
Investors have been selling the gold miner's shares today following news of a leadership change.
According to the release, Northern Star's managing director, Stuart Tonkin, has advised the board of his intention to step down during the first quarter of FY 2027.
Tonkin will remain in the role until that time, which the company notes will see the conclusion of its current strategic plan and the commissioning of the KCGM Fimiston Mill Expansion.
Major leadership change
Tonkin has been with Northern Star for 13 years, serving as chief operating officer and chief executive officer.
The company notes that during his tenure, it grew from a small Western Australian gold miner into Australia's largest ASX-listed gold producer, with three production centres and more than 10,000 staff and contractors across Western Australia and Alaska.
It also highlighted his role in major acquisitions and integrations, including Plutonic, Kanowna Belle, Kundana, Jundee, South Kalgoorlie, Pogo in Alaska, Kalgoorlie Consolidated Gold Mines, the merger with Saracen Minerals, and the takeover of De Grey Mining.
Commenting on his decision to leave, Tonkin said:
After 13 years leading Northern Star through significant growth, I'm proud to leave the Company in an exceptional position. The team, the assets and the outstanding growth outlook is unique and after many years of rewarding challenges, I have decided to step down.
I am very proud of what we have achieved at Northern Star and I want to especially thank my executive team and all our staff and contractors for the role they've played in building such a great company over the years, there is an exciting future ahead.
Northern Star's chair, Michael Chaney, thanked Tonkin for his contribution, noting that he would leave a legacy of assets and growth opportunities for the company. He commented:
On behalf of the Board and our shareholders, I want to thank Stu for his phenomenal efforts over the last 13 years. He can be rightly proud of his achievements, and he will leave a legacy in the form of assets and growth opportunities that will deliver benefits for all stakeholders for decades to come. Along with my fellow Directors, I look forward to working with Stu to achieve a smooth transition to a new leader in the coming months.
Succession process underway
Northern Star said the board has started a formal process to facilitate an orderly transition to a new managing director.
A leading global search firm will be appointed shortly, with the board to consider both internal and external candidates.
2026 has been very turbulent for Northern Star shares and this latest news certainly adds to it. So much so, following today's move, the gold miner's shares are down almost 25% year to date.
