VAL D'OR, QUEBEC --(June 9, 2009) - Northern Star Mining Corporation (TSX VENTURE:NSM) (Northern Star Mining or the "Company") is pleased to announce further drill results from its surface and underground drill programs.

On its wholly owned Malartic-Midway gold project (16km west of Val-d'Or, Quebec), drilling was carried out from surface on the Briar zones, on the L-Zone exploration extension, and from underground in the Chabela West Zone.

Highlights include 16.78 grams per tonne gold over 12.6 meters in the Briar Zone and 7.36 grams per tonne gold over 21 meters from underground in the Chabela West Zone.

BRIAR

Drilling from surface in the Briar Zone, prior to the planned 2009 bulk sampling (mining) from underground in this zone returned:

                  
HOLE #      From (m)    To (m)  Core length (m)  Grade (g/t Au)   Rock Type

                  
181            78.4      91.0             12.6            16.8    Gabbro

                  
182            83.4      86.7              3.3            8.24    Gabbro

                  
177            87.0      89.8             2.85            14.6    Quartz

                  

The true width of the Briar Zone is approximately 70% of core length.

L-ZONE

The newly discovered L-Zone continues to demonstrate significant gold values following the release of the original discovery holes (see press release June 4, 2009).

The fourth hole drilled on the L-Zone exploration extension returned:

                  
HOLE #      From (m)    To (m)  Core length (m)  Grade (g/t Au)   Rock Type

                  
172           202.5     204.8              2.3           16.03    Quartz

                  

True width of the L-Zone is approximately 75% of core length.

CHABELA WEST UNDERGROUND

Drilling from the Chabela West drift (138 meter level underground) downwards returned the following:

                  
HOLE #      From (m)    To (m)  Core length (m)  Grade (g/t Au)   Rock Type

                  
MU 026        Drift     -21.0
           floor (0)   meters             21.0            7.35    Gabbro
       (-138 meters)

                  

The true width of the zone is approximately 50% of the core length.

Following the above result, Northern Star is now planning to drive a drift below the 138 meter level at Chabela West to access, explore and sample this zone below the present Chabela West workings.

"The above results continue to expand the potential of the Malartic-Midway gold project. The Briar Zones continues to return significant gold values over impressive widths, while the L-Zone result continues to confirm its potential. Finally, underground drilling at the Chabela West drift (138 meter level) has discovered the downward extension of the Chabela West Zone", according to Michel David C.E.O.

DECLINE

Following the discovery in the Decline (see press release, June 4, 2009) of the possible extension of the K-Zone at the 173 meter level underground, the Company has begun drifting in this zone for future exploration and drilling.

Exploration continues in all these zones and further results are expected shortly.

MCKENZIE BREAK

Following the option agreement with Britannica Resources (see press release April 28, 2009), Northern Star has been studying the construction of a decline on one of the known gold mineralized structure on this project.

Britannica Resources has released a series of previously unannounced drill holes. Results include:

                  
HOLE #      From (m)    To (m)  Core length (m)  Grade (g/t Au)

                  
125           101.0     102.0              1.0            2.67
              216.0     228.8             12.8           1.807
Including     217.6     222.0              4.4           3.679

                  
128           152.3     154.4              2.1          10.867

                  
130            67.0      68.0              1.0            15.0

                  
131           305.7     315.0              9.3           1.877
Including     307.1     309.1              2.0           4.286

                  
132           354.0     355.5              1.5            18.1

                  

These results are principally centered on zone #4, which is dipping 15 degrees to the northeast. The drilling was conducted to intersect the gold mineralized structure at 90 degrees, therefore the core lengths are fairly close to true width.

The diamond drilling and exploration programs are being carried out under the direct supervision of Eugene Gauthier, Ing (OIQ). The Company is maintaining strict standards for QA (quality assurance) and QC (quality control); by keeping under lock all drill cores, rejects and pulps for further testing. Samples were sent to ALS Chemex and Techni-Lab labs in Val d'Or, Quebec. High grade assays intersections were subject to total gold metallic sieve method in addition to the standard fire assay and AA finish.
