Northern Star Announces That It Plans to Begin Diamond Drilling on the Callahan Project in February 2008

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 19, 2007) - Northern Star Mining Corp. ("Northern Star" or the "Company") (TSX VENTURE:NSM): is pleased to announce that it plans to begin diamond drilling on the Callahan project in February of 2008.

Further to the Company's press release of October 31, 2007, Northern Star Mining has completed its due diligence review and has vested into the option agreement.

To date on the project, 13 gold bearing targets have been identified. These targets were explored in the early part of the 1980's, and no recent exploration has taken place on this significant claim group, contiguous to the west with the former Kiena Gold Mine, presently in production and operated by Wesdome. To the west of the property lies the former producers Kierans-Norlartic (production 1,750,000 tons @ 4.5 g/t Au) and Marban (production 2,000,000 tons @ 5.3 g/t Au).

Recently, Niogold completed surface diamond drilling at the site of these former producers, and was successful at extending these structures laterally and at depth. All the gold bearing structures known on the adjacent properties to the east (Wesdome), and to the west (Niogold), have been projected onto the Callahan project.

The North-North zone of Niogold is projected to enter the Callahan property at depth and laterally to the east. Furthermore, the lateral eastern extension of the Norlartic structure has already been identified on the Callahan claims and is referred to as zone 13, where drilling in the 1980's intersected moderate gold values requiring follow up drilling. Mainly on these two structures, Niogold published a 43-101 compliant resources estimate (indicated + inferred) of 4,937,000 tonnes grading 2.70 g/t Au. The recent drilling further east on Marban by Niogold intersected significant gold intersections in structures representing the lateral and depth extensions of the former mine. These structures were also projected onto Callahan.

Zone #4 on the Callahan project was the site of an underground exploration program in the early 1980's. A 230 meter exploration shaft was sunk by Falconbridge Ltd, and a 1.5km drift extended at a depth of 200 meter to the northeast.

Zone #4 is the better known. Falconbridge Ltd calculated an historical drill-indicated total resource of 2.25 million tons at an uncut grade of 1.70 g/t Au within two adjacent blocks. The above resources are historical in nature having been estimated prior to May 30th 2003 (CIMM current and adopted guidelines). The Company is not treating these historical estimates as current mineral resources as defined under 43-101. The Company's geologists did not conduct any detailed work including QA (Quality Assurance) and QC (Quality Control) to tentatively upgrade these resources as a current 43-101 compliant resource. Falconbridge described the gold mineralization of zone # 4 as: "Gold mineralization in quartz veinlets occurs in intense zones of alteration hosted by a structurally complex, east-west trending shear zone where it crosscuts a northeast trending monzonite intrusion. The zone occurs approximately 160 meters beneath Lac de Montigny and is interpreted to plunge to the northeast onto the Wesdome property at 300 meters below surface."

Preliminary compilation by the Company also identified gold bearing structures close to and south west of the Callahan shaft. Zone #2 returned gold values of up to 8.71 g/t Au over 5.2 m. The Company can access this structure from surface and underground, and presently owns another headframe (in addition to its headframe at Shaft #1 at its Malartic-Midway project) at its Beacon gold mill that can be recycled to the Callahan site.

Initially diamond drilling will target known gold zones and will consist of approximately 30 drill holes. Following the preliminary results, the Company intends to carry out an aggressive detailed drill program on this project.

The Callahan project consists of 79 claims comprising 2,181 hectares (5,387 acres) and is located less than 2km to the northeast of the Company's Malartic-Midway project (116 claims for 3,142 hectares), where exploration and development work at Shaft #1 and the Decline is presently underway (see press release December 12, 2007).

Claude P. Larouche, Geol. Ing. (OIQ) acts as the qualified person of the Company and has reviewed the contents of the news release.

The Company looks forward to 2008 with continued surface and underground drilling and bulk sampling at its Malartic-Midway project, and its new exploration program beginning on its Callahan project.

Northern Star Mining is also receiving additional results from the definition drilling completed in 2007 on the Malartic-Midway project. After verification and compilation these results will be published as soon as available.
