Northern Star Resources Limited (ASX: NST) is pleased to advise that its heavy emphasis on financial and Shareholder returns is continuing to produce results, with the Company generating record free cashflow of A$183 million in the year to 30 June 2015.

The strong cashflow resulted in Northern Star ending the financial year with A$178 million in cash, bullion and investments, up from A$96 million a year earlier.

This came despite the Company spending A$82.5 million to acquire the Jundee Gold Mine and A$50 million on exploration during the year.

The outstanding cash generation enabled Northern Star to pay A$26.5 million in fully-franked dividends during the year (a total of 4.5c a share).

Northern Star’s financial performance was underpinned by record gold sales of 152,447oz in the June Quarter. This took the year’s sales to 580,784oz, comfortably within its guidance range.

ASX ANNOUNCEMENT – 9 JULY 2015

All-in sustaining costs for both the June Quarter and the full year are expected to come in at the lower end of the Company’s guidance range of A$1,050-$1,100/oz.

The price received in the June Quarter averaged A$1,498/oz compared with the current spot price of ~A$1,550/oz.

Northern Star spent A$15.9 million on its extensive drilling and exploration program in the June Quarter, taking this total to A$50 million for the financial year.

Northern Star Managing Director Bill Beament said the excellent performance reflected the priority the Company placed on financial and Shareholder returns, not just tonnes and ounces.

“We say we are a business first and a mining company second and these results demonstrate that emphasis,” Mr Beament said.

“Our production performance, throughout the year was outstanding and our costs were tightly controlled. In these areas, we have met our market guidance comfortably.

“But the real test of any mining company’s performance is what happens to its bank account and that of its Shareholders.

“We have excelled in those areas, as shown by the significant increase in our cash position, the elimination of our bank debt and the payment of A$26.5m in fully-franked dividends.

“It is also very pleasing to note that we have achieved this performance while investing A$50 million in exploration during the year. This program is generating strong results which I have no doubt will lead to further increases in our gold inventory and mine lives.”

Northern Star plans to release its full June quarterly report in the week commencing 20 July 2015.
