VAL D'OR, QUEBEC -- (Marketwire) -- 10/27/09 -- Northern Star Mining Corp. (TSX VENTURE: NSM)(OTCQX: NSMSF) (Northern Star Mining or the "Company") is pleased to announce further drill results from its surface and underground exploration and development programs.



Malartic-Midway Project


Underground drilling on the Malartic-Midway gold project (16km west of Val-d'Or - Quebec, immediately adjacent to the Osisko gold project) resulted in the following results:

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

44             Drift wall
                        0          8          8       6.92       Gabbro

69            Drift floor
                     30.7       32.9        2.2       8.35       Gabbro

Underground development of the Briar bulk sampling program is continuing while blasting (mining) of the Chabela bulk sample is underway.



Gold mineralization has been encountered in the main Briar haulage decline, following which the Company decided to drift into the porphyry for exploration and if warranted bulk sampling purposes.



During advancement of this exploration drift, a previously unknown gold mineralized gabbro was discovered.



Grab and muck samples along the face and from the muck haulage trucks returned an average cut grade of 14.8g/t over a true horizontal width of 4.5 meters. The Company has now advanced this drift over 40 meters in mineralized porphyry and gabbro.



A blast test hole (3.7 meters in length) in the gabbro ahead of drifting returned an average cut grade of 9.68g/t.



Drifting into the underground discoveries at the L and K zones (previously announced) is underway and the Company has contracted an immediate 4,000 meter underground drill program for these and other underground drill sites.



Beacon Mill


The Company is now set to begin milling operations at its wholly owned Beacon mill for the processing of its Malartic-Midway bulk samples in mid November.



McKenzie Break


At the McKenzie Break gold project (60-40 joint venture with Britannica Resources Corp.) the Authorization permits have been received from the Quebec government allowing underground work to proceed.



Site installation and capital equipment purchases are well underway, and the initial blasting and excavation work for the decline Portal (entrance) has begun.



Callahan Project


Surface diamond drilling on the Callahan gold project, located north of the Malartic-Midway project has also begun.



Michel David, president, states, "The Company has now entered into an acceleration exploration development phase. Underground bulk sampling at the Chabela, Briar and the newly discovered gabbro zone at Malartic-Midway is underway along with exploration diamond drilling and drifting. Underground exploration and development has begun at the McKenzie Break project, and finally surface diamond drilling has begun at the Callahan project. This increase in activity portends well for the Company's future."
