NORTHERN STAR RESOURCES LTD — AGM Information 2021

ASX Announcement 18 November 2021

CHAIRMAN’S AGM ADDRESS & MANAGING DIRECTOR’S PRESENTATION

Ladies and Gentlemen, I welcome you to our Annual General Meeting of Shareholders of Northern Star Resources Limited.

My name is Michael Chaney and I am the Chairman of your Company.

Can I say how pleased I was to have been invited to join the Northern Star Board as Chairman. I had watched the development and progress of Northern Star and Saracen over the years and was impressed by the way the “merger of equals” had been executed.

In my initial discussions with the senior management team and directors I liked what I saw in terms of corporate culture. It’s fair to say that the Northern Star and Saracen cultures were closely aligned, with a lot in common: a strong shareholder-return focus, a conviction that they could be the best in the world at operating mines, a care for all stakeholders, a strong set of ethical values, a can-do attitude and a really entrepreneurial spirit.

The Board and Management are determined that notwithstanding the fact that Northern Star is now a much bigger company, that spirit of entrepreneurship is not lost.

The Company itself has many attractive features: high quality assets which generate strong cash flows and, importantly, have realistic expansion opportunities and long mine lives; a strong balance sheet; skilled operational management and a highly skilled workforce.

The plan which Stuart Tonkin has outlined to the market, to increase production to two million ounces per annum over the next five years, while reducing our cost per ounce, is eminently realisable.

Understandably, the merger was followed by a number of changes at the Board and senior management level. As I did in this year’s Annual Report, I acknowledge the great contribution to the two companies’ success by the outgoing directors: nonexecutives Shirley In’t Veld and Peter O’Connor and executive directors Bill Beament and Raleigh Finlayson – the latter two having developed Northern Star and Saracen from gold mining juniors to the significant companies they were at the time of the merger. We’re looking forward to Raleigh rejoining the Board in a non-executive capacity next April.

We were very pleased to welcome Sharon Warburton to the Board in September this year and will benefit from her board experience across a range of industries, resources in particular.

At the close of this meeting Tony Kiernan retires as a non-executive and Lead Independent Director. Tony’s extensive experience over 35 years in the management, operation and direction of public-listed companies has been of great benefit to the Board and we shall miss his wisdom around the board table.

I’m confident that we are now positioned with the right mix of skills to take the Company forward successfully and to achieve healthy growth. From the Board’s perspective, one assurance I can give you with regard to growth is that our future decisions will be based on creating shareholder value rather than building a larger empire.

Northern Star is an exciting place to be involved with and I look forward to helping the Company fulfil its ambitions.

I now hand over to Stu Tonkin to report on current activities and the Company’s prospects going forward.

Authorised for release to the ASX by Michael Chaney, Chairman.
