Northgate Minerals Announces Diamond Drill Results Adjacent to Established
Reserves on the Young-Davidson Property

    
    Hole YD09-120 Intersects Mafic Volcanic Mineralization Grading 7.6 g/t
    Over 13.5m
    

VANCOUVER , Oct. 13 /CNW/ - Northgate Minerals Corporation (TSX: NGX, NYSE Amex: NXG) is pleased to report drill results for 29 shallow diamond drill holes totalling 2,424 metres (m) at its 100%-owned Young-Davidson project near the town of Matachewan in northern Ontario. Drilling took place on Northgate's Young-Davidson property immediately east of the current ore reserve in and around historic mine workings, which was operated by Matachewan Consolidated during the mid 1900s (1934-1954).

    
                               Drill Highlights

    -   Hole YD09-120, beyond the eastern limit of historic mining,
        intersected 7.6 grams per tonne (g/t) gold over 13.5m

    -   Hole YD09-114, south of historic mining, intersected 13.8 g/t gold
        over 2.0m and 7.1 g/t gold over 3.8m

    -   Holes YD09-132, within historic near surface workings, intersected
        1.9 g/t gold over 36.1m including 7.0 g/t over 5.0m
    

Ken Stowe , President and Chief Executive Officer, remarked, "This is our first exploration program targeting the higher grade mafic volcanic hosted gold mineralization east of the currently known syenite hosted gold reserves on the Young-Davidson property. While the open pit potential tonnage is modest, holes such as YD09-120 and YD09-114 indicate that there is still higher grade mafic volcanic gold mineralization to be discovered on the property."

    Diamond Drill Program
    

The purpose of the 2009 exploration diamond drill program to the east of the Young-Davidson deposit was to assess the potential for high grade mafic volcanic hosted gold mineralization within 50m of surface, which would have the potential to add open pit reserves in and around existing mine workings.

Select surface holes are listed in Table 1 below and the complete list of holes are listed in Table 2. All surface holes are plotted on Figure 1, a geology map of a portion of the Young-Davidson property.

Overview of Young-Davidson Exploration Area

Gold mineralization on the Young-Davidson property is present primarily in an intrusive syenite host rock dipping at approximately 70 degrees to the south. Figure 1, shown below, presents a portion of the property geology and the location of the holes reported herein to the east of the currently known reserves between 22,700E and 23,800E.
