Underground Development

Drifting and development of the North Briar zone prior to bulk sampling (mining) is continuing.

Exploration drifting into the Briar porphyry and into a newly discovered gold zone is ongoing. Following the discovery of visible gold in the porphyry, exploration drifting continued and encountered a previously unknown gabbro zone. Samples returned values of up to 14.8g/t over 4.5 meters (previously reported, see press release October 27, 2009)

Further to the above, the drift has now advanced a further 10 meters and has encountered quartz veins in porphyry with sections of significant free visible gold. Exploration work continues. Preparation for the installation of the second escape manway and ventilation raise is underway.

The first long hole blast in the Chabela zone has been completed and mucking of the initial 4,000 tonnes is underway.

Beacon Mill

The Beacon Mill start up is scheduled for November 23, with an initial 5-7 day run of waste rock for bedding of the mill. Presently the rod and ball mills have been loaded and prepared for operations.

The CSST (Quebec government worker safety board) has carried out the final inspection of the mill and approved it for operations.

McKenzie Break

At the McKenzie Break project, blasting and excavation of the decline portal entrance will be complete by November 20. Bolting and screening of the portal walls will begin by the week of November 23.

Surface building, compressor and genset installation is also underway.

Callahan Project

Surface drilling on the Callahan gold project, located north of the Malartic-Midway project is also ongoing.

Michel David, president states "the Company continues its growth with two underground exploration and development programs underway. The start up of our Beacon Mill for processing of the material sampled from the Chabela and porphyry zone and later for the Briar is an exciting time for all involved. The underground bulk sampling from the McKenzie Break project (February 2010) is greatly anticipated. The fact that we have been accident and injury free, demonstrates the professionalism of all those employees and contractors at Northern Star's".

Eugene Gauthier, Ing (OIQ), acts as the qualified person of the Company and has reviewed the contents of the news release. 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.
