NORTHERN STAR ANNOUNCES CORPORATE UPDATE

 

 

Val d’Or, Quebec, September 25 2008 – Northern Star Mining Corporation (TSX:NSM) (Northern Star Mining or the “Company”) is pleased to update the following:

 

1)             Construction of the Decline is progressing on schedule and on budget.

2)             Surface and underground drilling has been underway since May 2008 in the Malartic-Midway project.

3)             Surface diamond drilling on the Callahan project (Kinross/Inmet agreement).

4)             Surface diamond drilling beginning next week on the Revillard and Malartic Break projects.

 

The decline is advancing towards the “Chabela Zone”, and will continue towards the “Briar Zone”. Any mineralized material encountered is stockpiled at this time. A re-evaluation of the geology and structure confirmed that two main gold bearing structures are present on the Midway property.  A higher grade “gabbro-type  gold mineralization (6.00 g/t Au)  and a lower grade “Porphyry type gold  mineralization (2.70 g/t Au).  Presently, mineral resources are largely located between surface to a depth of 350 meters. The recent (July 2008) 43-101 compliant mineral resources report started the resources as:

 

Indicated

Gabbro             930,107 tonnes  grading 5.83 g/t Au                    (174,293 ounces Au)

 Porphyry          1,509,732 tonnes           grading 2.40 g/t Au                    (116,492 ounces Au)

 

Inferred

Gabbro             572,412 tonnes  grading 6.56 g/t Au                    (119,884 ounces Au)

Porphyry           1,469,795 tonnes           grading 2.40 g/t Au                    (113,410 ounces Au)

 

Historical Resources not yet classified by Northern Star

Shaft # 2           788,158 tonnes  grading 6.10 g/t Au                    (156,391 ounces Au)

Callahan #4       2,480,158 tonnes           grading 1.71 g/t Au                    (124,008 ounces Au)

Amlartic            304,001 tonnes  grading 3.10 g/t Au                    (27,360 ounces Au)

 

Note: Resources are in situ, non diluted, applying a lower cut-off grade of 1.03 g/t Au for the porphyries and 1.71 g/t Au for the gabbros. The historical resources are historical in nature and were estimated prior to May 30th, 2003 (CIM) and current and adopted guidelines.  The Company is not treating these historical resources as current mineral resources under NI-43-101 and they should not be relied upon. Northern Star is planning surface exploration and compilation to upgrade these resources into a 43-101 compliant format.

 

 

Surface diamond drilling resumed on the Malartic-Midway project in May 2008.

 

Approximately 9,000 meters has been carried out on the “Chabela Zone”, with over 1,600 samples sent to lab for assay. Results will be released as available.

 

A new gold mineralized porphyry-gabbro was discovered at a depth of 200 meters, on the new SE Briar Extension. 5 holes, to date for, a total of 2,500 meters have been drilled in this new structure which includes a new porphyry, with an associated gabbro showing significant pyrite mineralization. Assay results will be released when available. This new zone is located approximately 400 meters west of the decline.

 

On the Kinross-Callahan project, surface drilling started early September and a total of 8 holes have been completed to date.  The drilling is testing a new gold mineralized structure parallel and south of the “Amlartic Zone”, and also adjacent to the west of the Callahan shaft (250 meters deep)

 

Following a compilation of last year’s drilling on the Revillard project, additional diamond drilling was recommended and will begin in early October along with drilling on the Malartic Break property (Joint Venture with Britannica Resources Corp). A minimum of 3,000 meters is planned.

 

Northern Star is also evaluating the acquisition of other significant gold projects.

 

Claude P. Larouche has accepted the position of Executive Vice-president. Mr. Larouche has a BSc geological engineering from University of Quebec (1972) and MSc geology from Carleton University (1974). Mr. Larouche has over 30 years of experience in mining and exploration projects throughout North America with emphasis on the Abitibi gold belt.

 

Mr. Michel David, president, states that “with the addition of Mr. Larouche to our management team, the Company now has the experienced personnel in place to move the Company toward its goal of becoming a producing gold Company. Underground decline construction is going very well as is our underground and surface exploration programs. The goal of the ongoing exploration program is to guide the planned bulk sampling initially at the “Chabela Zone”, plan the extension to the “Briar Zone”, and expand the resource base. The new discovery at SE Briar will also be evaluated from underground”.

Larouche, Geol, 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 Claude P. Larouche, 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 labs in Val d’Or, Quebec.
