VAL D'OR, QUEBEC-- 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 (16 km west of Val-d'Or, Quebec), drilling was carried out from surface on the Briar zones, and from underground in the Chabela West Zone.

Highlights include 8.25 grams per tonne gold over 7.91 meters in the Briar Zone and 10.52 grams per tonne gold over 18.2 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:

                                              Core
                    From              To    length      Grade       Rock

Including          86.09           89.84      3.75      17.15     Gabbro

185                112.0           116.0       4.0      12.36     Gabbro

UNDERGROUND CHABELA WEST

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

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

MU 005       Drift Floor    -13.3 meters     -13.3       5.31     Gabbro
            (-138 meters)

MU 033A      Drift Floor     -18.2 meter     -18.2      10.52     Gabbro
            (-138 meters)

DECLINE

The Decline continues to advance, now reaching over 2 km. Preparations for bulk sampling (mining) in the Chabela West zone at the 138 meters level are being finalized, while the bulk sampling (mining) in the Briar Zone at the 200 meter level is under preparation. The decline has now reached the 180 meter level.

"We continue to receive very significant results from our surface and underground drill programs. The confirmation of these results combined with the construction and advancement of our underground access and development program bodes well for the future of our Company," according to Michel David, CEO.

Further results are expected shortly.

MCKENZIE BREAK

Following the option agreement with Britannica Resources (see press release February 23, 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 new drill holes. Results include:

                                                Core

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.
