KEY POINTS

 Second round of solid results from infill holes drilled by Northern Star at the Central Tanami Project in the Northern Territory

 Latest results continue to support Northern Star's strategy to enhance its confidence in the key Groundrush deposit at Central Tanami ahead of developing a +125,000ozpa operation

 The 20,000m Diamond drill program is aimed at improving the confidence level of the existing 1Moz Resource by infill drilling down to a vertical depth of 300m below the surface

 Northern Star is sole-funding this drilling program, in addition to refurbishing the processing plant, to earn 60% of the Project

 As at end of December, 16,000m (80%) of the drilling program had been completed with results to date in line with Tanami Gold's previous drilling

• 0.3m @ 359gpt gold

Northern Star Resources Limited (ASX: NST) is pleased to advise that its infill drilling program at the Central Tanami Project in the Northern Territory has returned a second batch of solid results.

The assays for the latest 23 infill Diamond holes at the Project's key Groundrush deposit are in line with those from the first 22 holes (see ASX release dated 10 December 2015) and those recorded by Tanami Gold previously (refer to Figure 1).

The drilling is aimed at establishing Northern Star's confidence in the Central Tanami Project in the lead-up to a decision to commence refurbishing the Project's processing plant and start production in the 2018 financial year.

The 20,000m drilling program and proposed plant refurbishment is being sole-funded by Northern Star as part of its agreement with Tanami Gold NL (ASX: TAM) to earn 60% of the Project.

Northern Star has earmarked Central Tanami as one of the sources of organic growth which will lift the Company's production to 700,000ozpa by FY18.

The current infill drilling program, now 80% completed, is focusing on establishing the continuity of mineralisation to a vertical depth of 300m below the surface providing Northern Star with the knowledge and confidence needed to design an underground mining operation via declines from the existing Groundrush open pit.

From these preliminary mine designs, Northern Star will then determine the capacity for the processing plant refurbishment to earn its 60% interest in the Central Tanami Project.

The remaining drilling program is expected to be completed in late January this year with final assays in by the end of the March Quarter.
