Northern Star Mining Corporation: Northern Star Announces Further Drill Results From Malartic-Midway Project

VAL D'OR, QUEBEC--(Marketwire - Sept. 30, 2009) - Northern Star Mining Corp. (TSX VENTURE:NSM) (Northern Star Mining or the "Company") is pleased to announce further drill results from its surface and underground exploration programs.

On its wholly owned Malartic-Midway gold project (16km west of Val-d'Or, (Quebec), drilling was carried out from surface on the Midway area and from underground in the Chabela, and Decline area.

Highlights include 8.9 grams per tonne gold over 7.5 meters from surface in the Midway area and 9.0 grams per tonne gold over 12.0 meters from underground. In addition, lower grade surface porphyry mineralization of the Osisko-Goldex type returned 1.17 grams per tonne gold over 12.0 meters at a depth of approximately 30 meters.

Results include:

DECLINE

To date, the Company has completed over 2.1km of decline construction and has now reached the North Briar Zone area.

The decline has reached and is presently within the North Briar porphyry, where mineralization has been encountered. Visible gold within quartz veins in the porphyry have been intersected in the decline advancement face.

Development to the Briar gold mineralized zone is ongoing.

Michel David, president reports "that these results are very significant in showing the continuity and persistence of the gold mineralization at the Malartic-Midway project, both from surface and underground".

MCKENZIE BREAK

At the McKenzie Break project, construction of a decline for underground bulk sampling is presently in its start up stages. Initial site clearing and installation has begun with actual decline portal construction planned for November of this year.

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.
