Northern Star Resources Limited (ASX: NST) is pleased to report on what has been a defining six months for the Company, marked by outstanding growth in production, profits, free cashflow, dividends and return on equity.

The results, for the six months to 31 December 2014, incorporate for the first time all of Northern Star's recent acquisitions. The Jundee gold mine was transferred to Northern Star on 1 July last year while the Plutonic mine became part of Northern Star in February, and Kundana and Kanowna Belle in March.

These acquisitions underpinned gold sold of 292,840oz in the six months, up from 50,927oz in the previous corresponding period. The Company received an average price of A$1,407/oz and AISC were A$1,057 an ounce, inclusive of a A$49/oz non-cash rehabilitation expense.

ASX ANNOUNCEMENT - 17 FEBRUARY 2015

Revenue was 471 per cent higher at A$412.1 million and net profit after tax rose 573 per cent to A$51.1 million. This was despite incurring acquisition and restructuring costs of A$11.3 million in the period.

The strong result enabled Northern Star to double its fully-franked interim dividend to 2¢ a share (to be paid

Friday, 3 April 2015 with a record date of Tuesday, 31 March 2015 - shares will go ex-dividend on Friday,

27 March 2015). Northern Star paid a fully-franked final dividend of 2.5¢ for the full year in recent years. The

Board of Northern Star is intending to announce a formal dividend policy with its FY2015 full-year accounts.

The doubling of the dividend reflects Northern Star's surging cashflow and robust balance sheet.

During the period, the Company reduced its bank debt from A$70 million to just A$35 million. Subsequent to the half year end, the facility has been further reduced to A$20m. It expects to retire this facility early in the June Quarter.

Northern Star Managing Director Bill Beament said the growth in production and free cashflow was extremely satisfying because it showed the Company had achieved a key goal of becoming a major Australian gold miner with scale and asset diversity.

"The increased dividend and rise in the Company's return on equity from 7 per cent to 17.6 per cent half-on- half are the most important measures of Northern Star's achievements," Mr Beament said.

"Free cash flow, dividends and return on equity are the ultimate gauges of any Company's performance. By contrast, growing production and revenue are of limited value if they don't generate increased returns for Shareholders.

"The sharp increase in return on equity, along with the rise in earnings per share from 1.8¢ to 8.7¢ and the 100 per cent increase in the interim dividend demonstrates that we haven't generated growth for the sake of it.

"Instead, we have pursued growth purely as a means of delivering increased returns for Shareholders. Our

Company and its people can derive much satisfaction in what we have delivered to Shareholders."

Northern Star aimed to maintain production at an annual rate of 550,000-600,000ozpa at an AISC of

~A$1,050/oz to A$1,100/oz.

This financial performance underpins the Company's aggressive exploration budget to maximise resources

growth and mine lives across its portfolio.

The results came after spending A$14 million on exploration in the past six months. Northern Star has budgeted a total of A$50 million for this calendar year.

This exploration campaign is already generating outstanding results, as shown by yesterday's ASX announcements on the increased resource estimate of 1.1moz at the Pegasus deposit within the Kundana project and the revised resource estimate for the Jundee project.

"We aim to maximise Shareholder returns by generating strong cashflow from our operations and growth from exploration," Mr Beament said.

"Today's announcement demonstrates that we are achieving these objectives."

Yours faithfully

BILL BEAMENT Managing Director
